 ALX Oncology Holdings Inc., or the Company, was formed as a
 Delaware corporation on April&amp;#xA0;1, 2020, or Inception. The
 Company was formed for the purpose of completing the initial public
 offering and related transactions in order to carry on the business
 of ALX Oncology Limited. After Inception, ALX Oncology Limited
 became a wholly-owned subsidiary of the Corporation as result of
 the internal reorganization. As part of the transaction, all of the
 equity, option and warrant holders of ALX Oncology Limited became
 equity, option and warrant holders of the Company, holding the same
 number of corresponding shares, options and/or warrants in the
 Company as they did in ALX Oncology Limited immediately prior to
 the reorganization.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Net Loss Per Share Attributable to Common
 Stockholders&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Basic net loss per share is calculated by dividing the net loss
 attributable to common stockholders by the weighted-average number
 of shares of common stock outstanding during the period, without
 consideration for common stock equivalents. Diluted net loss per
 share is the same as basic net loss per share, since the effects of
 potentially dilutive securities are antidilutive given the net loss
 for each period presented.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company applies the &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method to compute basic and
 diluted net loss per share when it has issued shares that meet the
 definition of participating securities. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method determines net loss
 per share for each class of common stock and participating
 securities according to dividends declared or accumulated and
 participation rights in undistributed earnings. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method requires net loss
 available to common stockholders for the period to be allocated
 between common and participating securities based upon their
 respective rights to share in the earnings as if all net loss for
 the period had been distributed. The Company&amp;#x2019;s convertible
 preferred stock participate in any dividends declared by the
 Company and are therefore considered to be participating
 securities. The participating securities are not required to
 participate in the losses of the Company, and therefore during
 periods of loss there is no allocation required under the
 &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method.&lt;/p&gt;

 On July&amp;#xA0;21, 2020, the warrants to purchase 61,292 Series B
 convertible preferred stock issued to SVB and WestRiver with an
 exercise price of $9.4972 per share were automatically converted to
 warrants to purchase 61,292 shares of common stock at an exercise
 price of $9.4972 per share. The Company revalued the Series B
 convertible preferred stock warrants as of the completion of the
 initial public offering and reclassified the outstanding preferred
 stock warrant liability balance to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital with no further
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt; required as
 the common stock warrants are considered permanent equity.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 On August&amp;#xA0;17, 2020, SVB and WestRiver delivered the Notice of
 Exercise to net exercise 61,292 warrants at an exercise price of
 $9.4972 per share. Accordingly, the Company issued 48,932 shares of
 the Company&amp;#x2019;s common stock.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Dividends&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Cumulative dividends of 6.0% per annum of the original issue price
 for each preferred stock series are payable when and as declared by
 the Company&amp;#x2019;s Board of Directors, or Board of Directors, upon
 the occurrence of a liquidation event or upon a contingent
 mandatory conversion of the preferred stock in connection with a
 qualified initial public offering as described below. The Series A
 original issue price is $6.58, and the Series B and Series C
 original issue price is $9.4972. The original issue price is
 subject to adjustment in the event of any share dividend, share
 split, combination, consolidation or other recapitalization. The
 dividends shall accrue from day to day from the issue date of such
 preferred stock whether or not declared and shall be cumulative. In
 addition, the preferred stockholders participate on an &lt;font style="WHITE-SPACE: nowrap"&gt;as-converted&lt;/font&gt; basis in any dividends
 payable to ordinary shareholders. As of July&amp;#xA0;20, 2020, there
 were approximately $18.0&amp;#xA0;million of accrued cumulative
 dividends on the Series A, Series B and Series C convertible
 preferred stock, which became payable upon the consummation of the
 Company&amp;#x2019;s initial public offering and automatically converted
 into 2,564,759 shares of the Company&amp;#x2019;s common stock.&lt;/p&gt;

 &lt;b&gt;(8) LICENSE AGREEMENT&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;i&gt;Exclusive (Equity) Agreement with The Board of Trustees of the
 Leland Stanford Junior University&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 In March 2015, the Company entered into a license agreement, or the
 Stanford Agreement, with the Board of Trustees of the Leland
 Stanford Junior University, or Stanford, under which the Company
 obtained a worldwide, royalty-bearing, sublicensable license under
 certain patents relating to the Company&amp;#x2019;s current product
 candidates, to develop, manufacture and commercialize products for
 use in certain licensed fields, the scope of which would include
 the application of the licensed intellectual property in oncology.
 The license granted to the Company in the Stanford Agreement
 includes an exclusive grant, subject to certain &lt;font style="WHITE-SPACE: nowrap"&gt;pre-existing&lt;/font&gt; &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive&lt;/font&gt; or exclusive rights that
 Stanford retained for grant to third parties with respect to
 certain categories of the licensed patents in certain fields of use
 and retained rights by Stanford and all other nonprofit
 institutions to use and practice the licensed patents and
 technology for internal research and other nonprofit purposes. The
 license granted to the Company in the Stanford Agreement also
 includes &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive&lt;/font&gt;
 grants to certain Stanford patents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In consideration for the rights granted to the Company under the
 Stanford Agreement, the Company paid Stanford a nonrefundable
 license royalty and reimbursed Stanford for past patent expenses,
 together totaling less than $0.1&amp;#xA0;million, and granted Stanford
 a specified number of shares of common stock of the Company. In
 addition, the Company is obligated to pay Stanford ongoing patent
 expenses and an annual license maintenance fee, which are nominal
 and will be creditable against any royalties payable to Stanford in
 the applicable year. The Company is required to make milestone
 payments up to an aggregate of $5.0&amp;#xA0;million in respect of a
 specified number of licensed products that successfully satisfy
 certain clinical and regulatory milestones. No milestone payments
 have been made through September&amp;#xA0;30, 2020. The Company also
 agreed to pay Stanford tiered royalties on a specified percentage
 of net sales made by the Company, its affiliates and its
 sublicensees of licensed products at rates ranging within low
 single-digit percentages, subject to certain reductions and
 offsets. The license, on a licensed &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-licensed&lt;/font&gt;&lt;/font&gt; product and
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;country-by-country&lt;/font&gt;&lt;/font&gt; basis, shall
 become royalty-free and fully &lt;font style="WHITE-SPACE: nowrap"&gt;paid-up&lt;/font&gt; upon the later of the date on
 which the last valid claim included in the exclusively or
 &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusively&lt;/font&gt; licensed
 patents expires and ten years after the first commercial sale of
 the licensed product in such country.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company may terminate the Stanford Agreement, on a licensed
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-licensed&lt;/font&gt;&lt;/font&gt; product
 basis, at any time for any reason by providing at least 60
 days&amp;#x2019; written notice to Stanford. Stanford may terminate the
 Stanford Agreement, if the Company is in breach of any provision of
 the Stanford Agreement and fails to remedy such breach within 60
 days after written notice of such breach by Stanford. In addition,
 Stanford has the right to terminate the Stanford Agreement, on a
 licensed &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-licensed&lt;/font&gt;&lt;/font&gt; product
 basis, if the Company is not diligently developing and
 commercializing such licensed product under certain conditions or
 if the Company fails to achieve specified development milestones
 for such licensed product by certain dates, subject to the
 Company&amp;#x2019;s extension rights.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;i&gt;Commercial License Agreement with Selexis SA&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 In June 2016, the Company entered into a license agreement with
 Selexis SA, or Selexis, under which the Company obtained a
 worldwide, royalty-bearing, sublicensable license under certain
 patents, &lt;font style="WHITE-SPACE: nowrap"&gt;know-how&lt;/font&gt; and
 other intellectual property, to use Selexis generated cell lines to
 manufacture ALX148 and to make, use and sell licensed product
 containing such compound in all fields of use. The rights granted
 under this agreement include the rights to grant sublicenses to
 contractors or other collaboration partners, in each case to
 develop production processes or manufacture licensed product
 containing ALX148.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In consideration for the rights granted to the Company under the
 agreement, the Company paid Selexis a nominal &lt;font style="WHITE-SPACE: nowrap"&gt;one-time&lt;/font&gt; fee and will pay Selexis an
 annual maintenance fee. The Company also agreed to pay Selexis
 milestone payments up to an aggregate of 1.2&amp;#xA0;million Swiss
 Francs in respect of all licensed products developed and/or
 commercialized under the grant that successfully satisfies certain
 milestone events. The Company also agreed to pay Selexis a flat
 royalty of a very low single-digit percentage on net sales made by
 the Company, its affiliates and sublicensees of products. This
 royalty obligation, on a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-product&lt;/font&gt;&lt;/font&gt; and
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;country-by-country&lt;/font&gt;&lt;/font&gt; basis, shall
 terminate and become fully &lt;font style="WHITE-SPACE: nowrap"&gt;paid-up&lt;/font&gt; upon the passing of ten years
 after the first commercial sale of the product in such country, or
 the Company&amp;#x2019;s exercise of the royalty buyout option
 exercisable at any time prior to the first commercial sale of a
 licensed product.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company may terminate the license agreement at any time for any
 reason with at least 60 days&amp;#x2019; written notice to Selexis.
 Either party may terminate the license agreement if the other party
 enters into a bankruptcy event or in the event of a material breach
 of the agreement (that cannot be cured or remains uncured for 60
 days after the date that the defaulting party is provided with
 written notice of such breach). The Company&amp;#x2019;s obligations to
 pay royalties that are accrued or accruable will survive any
 termination of the agreement, and in certain circumstances the
 licenses granted under the agreement will terminate unless they
 have become fully paid up as described in the previous
 paragraph.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;i&gt;Commercial Antibody Agreement with Crystal Bioscience Inc. (Now
 a Subsidiary of Ligand Pharmaceuticals Incorporated)&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 In March 2017, the Company entered into an agreement with Crystal
 Bioscience Inc. (now a subsidiary of Ligand Pharmaceuticals
 Incorporated), or Crystal, under which the Company obtained an
 assignment of certain patents, covering certain SIRP&lt;font style="FONT-FAMILY: Times New Roman"&gt;&lt;font style="FONT-FAMILY: SYMBOL"&gt;a&lt;/font&gt;&lt;/font&gt; antibodies. Under this
 agreement, the Company also received a worldwide, royalty-bearing
 &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive&lt;/font&gt; license,
 with the right to grant sublicenses through multiple tiers of
 sublicenses, under certain of Crystal&amp;#x2019;s background patents
 and &lt;font style="WHITE-SPACE: nowrap"&gt;know-how&lt;/font&gt; necessary to
 commercialize the rights under the assigned patents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In consideration for the rights granted to the Company under the
 agreement, it agreed to pay Crystal milestone payments up to
 $11.1&amp;#xA0;million in respect of all licensed products developed
 under the assigned patents, that successfully satisfy certain
 clinical and regulatory milestones, each milestone being paid only
 once for all products. The Company also agreed to pay Crystal
 tiered royalties on net sales made by the Company, its affiliates
 and sublicensees of products at rates ranging within low
 single-digit percentages, subject to certain potential reductions.
 This royalty obligation, on a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-product&lt;/font&gt;&lt;/font&gt; and
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;country-by-country&lt;/font&gt;&lt;/font&gt; basis, shall
 terminate and become fully &lt;font style="WHITE-SPACE: nowrap"&gt;paid-up&lt;/font&gt; upon the later of the date on
 which the last valid claim included in the licensed patents expires
 and ten years after the first commercial sale of the product in
 such country.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company agreed to use commercially reasonable efforts to
 develop and commercialize licensed products, including meeting
 defined development milestones by certain specified dates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company may terminate the agreement at any time for any reason
 with at least 60 days&amp;#x2019; written notice to Crystal. Either
 party may terminate the agreement if the other party enters into a
 bankruptcy event or in the event of material breach of the
 agreement (that remains uncured for 60 days after the date that it
 is provided with written notice of such breach). The
 Company&amp;#x2019;s obligations to pay royalties and milestone payments
 which accrued &lt;font style="WHITE-SPACE: nowrap"&gt;pre-termination&lt;/font&gt; or accrue
 post-termination will survive any termination.&lt;/p&gt;

 &lt;i&gt;Guarantees and Indemnifications&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 In the normal course of business, the Company enters into contracts
 and agreements that contain a variety of representations and
 warranties and provide for general indemnifications. The
 Company&amp;#x2019;s exposure under these agreements is unknown because
 it involves claims that may be made against the Company in the
 future but have not yet been made. To date, the Company has not
 paid any claims or been required to defend any action related to
 its indemnification obligations. However, the Company may record
 charges in the future as a result of these indemnification
 obligations. The Company also has indemnification obligations to
 its officers and directors for specified events or occurrences,
 subject to some limits, while they are serving at the
 Company&amp;#x2019;s request in such capacities. There have been no
 claims to date and the Company has director and officer insurance
 that may enable the Company to recover a portion of any amounts
 paid for future potential claims. The Company believes the fair
 value of these indemnification agreements is minimal. Accordingly,
 the Company has not recorded any liabilities for these agreements
 as of September&amp;#xA0;30, 2020.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 4px"&gt;

 &lt;i&gt;Contingencies&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 From time to time, the Company may be a party to various claims in
 the normal course of business. Legal fees and other costs
 associated with such actions will be expensed as incurred. The
 Company will assess, in conjunction with its legal counsel, the
 need to record a liability for litigation and contingencies.
 Reserve estimates will be recorded when and if it is determined
 that a loss related matter is both probable and reasonably
 estimable. For the nine months ended September&amp;#xA0;30, 2020 the
 Company had no pending or threatened litigation.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company has contractual obligations from its operating lease,
 manufacturing and service contracts, Term Loan, and other research

 formulation development, process development and cGMP manufacturing
 of ALX148 for use in clinical trials on a project basis. The MSA
 had an initial term of three years with successive &lt;font style="WHITE-SPACE: nowrap"&gt;one-year&lt;/font&gt; renewal periods, is
 cancellable upon notice and is &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive.&lt;/font&gt; Statements of work
 under the MSA commit the Company to certain purchase obligations of
 approximately $7.5&amp;#xA0;million. In addition, the Company has
 commitments with a second drug product manufacturer that commits
 the Company to certain purchase obligations of approximately
 $0.1&amp;#xA0;million. These amounts are based on &lt;font style="WHITE-SPACE: nowrap"&gt;non-cancellable&lt;/font&gt; commitments and
 forecasts that include estimates of future market demand, quantity
 discounts and manufacturing efficiencies that may impact timing of
 purchases.&lt;/i&gt;&lt;/p&gt;

 The Company enters into contracts in the normal course of business
 with various third parties for clinical trials, preclinical
 research studies and testing, manufacturing and other services and
 products for operating purposes. These contracts generally provide
 for termination upon notice. Payments due upon cancellation consist
 only of payments for services provided or expenses incurred,
 including &lt;font style="WHITE-SPACE: nowrap"&gt;non-cancellable&lt;/font&gt;
 obligations of our service providers, up to the date of
 cancellation. These payments are not included in the table of
 contractual obligations above.&lt;/p&gt;

 &lt;b&gt;(5) TERM LOAN&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 The Company&amp;#x2019;s wholly-owned subsidiaries Alexo Therapeutics
 International and Sirpant Therapeutics, as borrowers, entered into
 a Loan and Security Agreement, or the Loan Agreement, dated as of
 December&amp;#xA0;20, 2019, with SVB and WestRiver, collectively as
 lenders, and SVB, as administrative agent and collateral agent.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 As a result of the internal reorganization, in May 2020 the Company
 entered into a Joinder and First Amendment to the Loan and Security
 Agreement, or the Joinder Amendment, and Amended and Restated
 Warrants to Purchase Stock, or the Amended Warrants. The purpose
 for entering into the Joinder Amendment was to add the newly
 established ALX Oncology Holdings Inc. as additional borrower to
 the Term Loan. Concurrently, the Company modified the Amended
 Warrants to change the issuer from ALX Oncology Limited to ALX
 Oncology Holdings Inc. The Company accounted for the First
 Amendment to the Loan and Security Agreement as a modification.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Loan Agreement provides for term loans in an aggregate
 principal amount of up to $10.0&amp;#xA0;million funded in two
 tranches, subject to the satisfaction of a certain milestone. The
 first tranche, in the amount of $6.0&amp;#xA0;million, was funded on
 the closing date of the Loan Agreement in December 2019. A second
 tranche of $4.0&amp;#xA0;million was available on or before
 March&amp;#xA0;31, 2020, upon the Company&amp;#x2019;s achievement of an
 equity financing resulting in net cash proceeds in an amount of at
 least $30.0&amp;#xA0;million to the Company. The Company elected not to
 draw down on the second tranche, which is no longer available.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The loans under the Loan Agreement bear interest at a floating per
 annum interest rate equal to the greater of 7.0% or 2.0% plus the
 prime rate as reported in The Wall Street Journal. The Wall Street
 Journal prime rate was 3.25% as of September&amp;#xA0;30, 2020.
 Therefore, the rate applicable to the Company as of
 September&amp;#xA0;30, 2020 was 7.0%.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company is required to make interest-only payments for the
 first 12 months after the closing of the Loan Agreement, followed
 by consecutive equal monthly payments of principal and interest
 commencing on January&amp;#xA0;1, 2021 and continuing through the
 maturity date of September&amp;#xA0;1, 2022. The Loan Agreement also
 provides for a final payment equal to 6.0% multiplied by the
 aggregate principal amount of the term loans funded, which is due
 on the maturity date, upon the acceleration of the term loans, or
 upon prepayment of the term loans. If the Company elects to prepay
 the term loans, there is also a prepayment fee of between 1.0% and
 3.0% of the principal amount being prepaid depending on the timing
 and circumstances of prepayment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In conjunction with the Loan Agreement, the Company has issued
 warrants to purchase 61,292 Series B convertible preferred stock to
 SVB and WestRiver with an exercise price of $9.4972 per share.
 Following the Company&amp;#x2019;s initial public offering, these
 warrants were automatically converted to warrants to purchase
 61,292 shares of common stock at an exercise price of $9.4972 per
 share. The estimated fair value of the warrants at the date of
 issuance was approximately $0.4&amp;#xA0;million. The Company revalued
 the Series B convertible preferred stock warrants as of the
 completion of the initial public offering and reclassified the
 outstanding preferred stock warrant liability balance of
 $1.0&amp;#xA0;million to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital with no further
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt; required as
 the common stock warrants are considered permanent equity effective
 July&amp;#xA0;16, 2020. The fair value of the common stock warrant was
 determined using a Black-Scholes option-pricing model with the
 following assumptions: an expected term of 9.8 years, a volatility
 of 84.2%, a dividend rate of zero and a risk-free rate of 0.6%. The
 changes in fair value in warrant liability was recognized as a
 component of other expense, net in the accompanying condensed
 consolidated statement of operations and comprehensive loss. On
 August&amp;#xA0;17, 2020, SVB and WestRiver delivered the Notice of
 Exercise for net exercise of 61,292 warrants at an exercise price
 of $9.4972 per share. Accordingly, the Company issued 48,932 shares
 of the Company&amp;#x2019;s common stock (Note 6).&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The loans under the Loan Agreement are secured by substantially all
 of the Company&amp;#x2019;s assets, except the Company&amp;#x2019;s
 intellectual property, which is the subject of a negative
 pledge.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company determined that certain loan features were embedded
 derivatives requiring bifurcation and separate accounting. Those
 embedded derivatives were bundled together as a single, compound
 embedded derivative and then bifurcated and accounted for
 separately from the host contract. The Company recorded a term loan
 compound derivative liability of approximately $51,000 which will
 be &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;marked-to-market&lt;/font&gt;&lt;/font&gt; in future
 periods. The Company calculated the fair value of the compound
 derivative by computing the difference between the fair value of
 the term loan with the compound derivative using the &amp;#x201C;with
 and without&amp;#x201D; method under the income approach, and the fair
 value of the term loan without the compound derivative. The Company
 calculated the fair values using a probability-weighted discounted
 cash flow analysis. The key valuation assumptions used consist of
 the discount rate and the probability of the occurrence of a change
 in control event. The term loan compound derivative liability is
 being &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; at each
 financial reporting period with any changes in fair value being
 recognized as a component of other expense, net in the condensed
 consolidated statement of operations and comprehensive loss. As of
 September&amp;#xA0;30, 2020, the fair value of the compound derivative
 liability was approximately $43,000 and was recorded in other

 The fair value of Series B convertible preferred stock warrant
 liability at issuance, fair value of embedded derivatives which
 were bifurcated and other debt issuance costs have been treated as
 debt discounts on the Company&amp;#x2019;s condensed consolidated
 balance sheet and together with the final payment are being
 amortized to interest expense throughout the life of the term loan
 using the effective interest rate method.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 As of September&amp;#xA0;30, 2020, there were unamortized issuance
 costs and debt discounts of $0.2&amp;#xA0;million, which were recorded
 as a direct deduction from the term loan on the condensed
 consolidated balance sheet. Interest expense for the term loan was
 $0.3&amp;#xA0;million and $0.7&amp;#xA0;million for the three and nine
 months ended September&amp;#xA0;30, 2020, respectively.&lt;/p&gt;

 In June 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-13,&lt;/font&gt; Financial
 Instruments-Credit Losses (Topic 326), which requires entities to
 measure all expected credit losses for financial assets held at the
 reporting date based on historical experience, current conditions,
 and reasonable and supportable forecasts. This replaces the
 existing incurred loss model and is applicable to the measurement
 of credit losses on financial assets measured at amortized cost.
 The Company early adopted this guidance on January&amp;#xA0;1, 2020.
 The adoption of this guidance did not have a material impact on the
 Company&amp;#x2019;s condensed consolidated financial statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;

 Measurement (Topic 820): Disclosure Framework&amp;#x2014;Changes to the
 Disclosure Requirements for Fair Value Measurement. The FASB issued
 final guidance that eliminates, adds and modifies certain
 disclosure requirements for fair value measurements as part of its
 disclosure framework project. Under the ASU, entities will no
 longer be required to disclose the amount of transfers between
 Level&amp;#xA0;1 and Level&amp;#xA0;2 of the fair value hierarchy. Public
 companies will be required to disclose changes in unrealized gains
 and losses for the period included in other comprehensive income
 for recurring Level&amp;#xA0;3 fair value measurements held at the end
 of the reporting period and the range and weighted average used to
 develop significant unobservable inputs for Level&amp;#xA0;3 fair value
 measurements. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2018-13&lt;/font&gt;
 is effective for public business entities for annual reporting
 periods, and interim periods within those annual periods, beginning
 after December&amp;#xA0;15, 2019, with early adoption permitted. The
 Company adopted this guidance on January&amp;#xA0;1, 2020. The adoption
 of ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2018-13&lt;/font&gt; did not
 have a material impact on its condensed consolidated financial
 statements.&lt;/p&gt;

 Property and equipment are stated at cost less accumulated
 depreciation. Depreciation of property and equipment is provided
 using the straight-line method over the estimated useful lives of
 the assets. Upon sale or retirement of assets, the cost and related
 accumulated depreciation or amortization are removed from the
 condensed consolidated balance sheet and the resulting gain or loss
 is reflected in the condensed consolidated statement of operations
 and comprehensive loss. Maintenance and repairs are charged to the
 condensed consolidated statement of operations and comprehensive
 loss as incurred.&lt;/p&gt;

 Research and development costs are expensed as incurred and consist

 Nonrefundable advance payments for goods or services to be received

 &lt;b&gt;&lt;i&gt;Revenue Recognition&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 To date, the Company has derived revenue from providing research
 and development services on a time and materials basis to a
 related-party.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company recognizes such revenues over time as services are
 delivered, and invoices the customer as the work is incurred in
 arrears.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company recognizes revenue when its customer obtains control of
 promised goods or services, in an amount that reflects the
 consideration which the Company expects to receive in exchange for
 those goods or services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 To determine revenue recognition for arrangements that the Company
 determines are within the scope of Topic 606, the Company performs
 the following five steps: (i)&amp;#xA0;identify the contract(s) with a
 customer; (ii)&amp;#xA0;identify the performance obligations in the
 contract; (iii)&amp;#xA0;determine the transaction price;
 (iv)&amp;#xA0;allocate the transaction price to the performance
 obligations in the contract; and (v)&amp;#xA0;recognize revenue when
 (or as) the Company satisfies a performance obligation.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 As part of the Company&amp;#x2019;s consideration as to whether the
 Company has entered into a contract with a customer, it considers
 whether it is probable that it will collect the consideration it is
 entitled to in exchange for the goods and services it transfers to
 the customer. At contract inception, the Company assesses the goods
 or services promised within each contract that falls under the
 scope of Topic 606, determines those that are performance
 obligations, and assesses whether each promised good or service is
 distinct. The Company then recognizes as revenue the amount of the
 transaction price that is allocated to the respective performance
 obligation when (or as) the performance obligation is
 satisfied.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Stock-based Compensation Expense&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company accounts for stock-based compensation by measuring and
 recognizing compensation expense for all stock-based payments made
 to employees, directors and &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees&lt;/font&gt; based on estimated
 grant-date fair values. The Company uses the straight-line method
 to allocate compensation expense to reporting periods over each
 optionee&amp;#x2019;s requisite service period, which is generally the
 vesting period, and estimates the fair value of stock-based awards
 to employees and directors using the Black-Scholes option-pricing
 model. The Black-Scholes model requires the input of subjective
 assumptions, including expected volatility, expected dividend
 yield, expected term, risk-free rate of return and the estimated
 fair value of the underlying common stock on the date of grant. The
 Company accounts for the effect of forfeitures as they occur.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company records convertible preferred stock net of issuance
 costs on the dates of issuance, which represents the carrying
 value. In the event of a change of control of the Company, proceeds
 will be distributed in accordance with the liquidation preferences
 set forth in its organization documents unless the holders of
 convertible preferred stock have converted their convertible
 preferred stock into common stock. Convertible preferred stock are
 classified outside of stockholders&amp;#x2019; equity (deficit) on the
 accompanying condensed consolidated balance sheets as events
 triggering the liquidation preferences are not solely within the
 Company&amp;#x2019;s control. The Company has elected not to adjust the
 carrying values of the convertible preferred stock to the
 liquidation preferences of such shares because of the uncertainty
 of whether or when such an event would occur. Upon the consummation
 of the Company&amp;#x2019;s initial public offering in July 2020, all
 shares of convertible preferred stock outstanding and accrued
 cumulative dividends automatically converted into 23,934,533 shares
 of common stock.&lt;/p&gt;

 The preparation of the condensed consolidated financial statements
 in conformity with U.S. GAAP requires management to make estimates
 and assumptions that affect the reported amounts of assets and
 liabilities and disclosure of contingent assets and liabilities at
 the date of the condensed consolidated financial statements and the
 reported amounts of revenues and expenses during the reporting
 periods. On an ongoing basis, management evaluates its estimates,
 including those related to the estimated useful lives of long-lived
 assets, clinical trial accruals, fair value of assets and
 liabilities, Series B convertible preferred stock warrant
 liability, term loan compound derivative liability, term loan,
 valuation of the Company&amp;#x2019;s common stock, income taxes and
 stock-based compensation. Management bases its estimates on
 historical experience and on various other market-specific and
 relevant assumptions that management believes to be reasonable
 under the circumstances. Actual results could differ from those
 estimates.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 0pt" align="left"&gt;&lt;i&gt;In November 2015, the Company entered into a Master
 Service Agreement, or the MSA, with KBI Biopharma, Inc. relating to
 formulation development, process development and cGMP manufacturing
 of ALX148 for use in clinical trials on a project basis. The MSA
 had an initial term of three years with successive &lt;font style="WHITE-SPACE: nowrap"&gt;one-year&lt;/font&gt; renewal periods, is
 cancellable upon notice and is &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive.&lt;/font&gt; Statements of work
 under the MSA commit the Company to certain purchase obligations of
 approximately $7.5&amp;#xA0;million. In addition, the Company has
 commitments with a second drug product manufacturer that commits
 the Company to certain purchase obligations of approximately
 $0.1&amp;#xA0;million. These amounts are based on &lt;font style="WHITE-SPACE: nowrap"&gt;non-cancellable&lt;/font&gt; commitments and
 forecasts that include estimates of future market demand, quantity
 discounts and manufacturing efficiencies that may impact timing of
 purchases.&lt;/i&gt;&lt;/p&gt;

 The functional currency of the Company&amp;#x2019;s operation and each
 of its subsidiaries is U.S. dollars. All assets and liabilities
 denominated in a foreign currency are translated into U.S. dollars
 at the exchange rate prevailing on the balance sheet date. Expenses
 are translated at the average exchange rates prevailing during the
 applicable period. Foreign currency transaction gains and losses
 are included in the consolidated statement of operations and
 comprehensive loss and recorded in other expense, net, and were

 The Company reviews property and equipment for impairment whenever
 events or changes in circumstances indicate that the carrying
 amount of an asset may not be recoverable. Recoverability is
 measured by comparison of the carrying amount to the future
 undiscounted net cash flows which the asset or asset group are
 expected to generate. If such assets are considered to be impaired,
 the impairment to be recognized is measured as the amount by which
 the carrying amount of the assets exceeds its fair value. Fair
 value is determined using various valuation techniques including
 discounted cash flow models, quoted market values and third-party
 independent appraisals, as considered necessary. There were no
 impairment charges recognized in the three and nine months ended
 September&amp;#xA0;30, 2019 and 2020.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company accounts for income taxes under the asset and liability
 method, which requires the recognition of deferred tax assets and
 liabilities for the expected future tax consequences of events that
 have been included in the condensed consolidated financial
 statements. Under this method, deferred tax assets and liabilities
 are determined on the basis of the differences between the
 condensed consolidated financial statement carrying amounts and tax
 bases of assets and liabilities using enacted tax rates in effect
 for the period in which the temporary differences are expected to
 reverse. The effect of a change in tax rates on deferred tax assets
 and liabilities is recognized in the condensed consolidated
 statements of operations and comprehensive loss in the period that
 includes the enactment date. The Company recognizes deferred tax
 assets to the extent that it believes these assets are more likely
 than not to be realized. In making such a determination, the
 Company considers all available positive and negative evidence,
 including future reversals of existing taxable temporary
 differences, projected future taxable income, &lt;font style="WHITE-SPACE: nowrap"&gt;tax-planning&lt;/font&gt; strategies and results of
 recent operations. If the Company determines that it would be able
 to realize its deferred tax assets in the future in excess of their
 net recorded amount, it would make an adjustment to the deferred
 tax asset valuation allowance, which would reduce the provision for
 income taxes. The Company recognizes benefits of uncertain tax
 positions if it is more likely than not that such positions will be
 sustained upon examination based solely on their technical merits,
 as the largest amount of benefit that is more likely than not to be
 realized upon the ultimate settlement. The Company&amp;#x2019;s policy
 is to recognize interest and penalties related to the underpayment
 of income taxes as a component of income tax expense or
 benefit.&lt;/p&gt;

 On April&amp;#xA0;1, 2020, the board of directors approved a new equity
 incentive plan, or the 2020 Equity Incentive Plan, that replaced
 the 2015 Share Award Scheme.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In July 2020, the Company adopted the Amended and Restated 2020
 Equity Incentive Plan, or the 2020 Plan. The 2020 Plan replaced the
 Company&amp;#x2019;s 2020 Equity Incentive Plan and a total of 7,874,862
 shares were reserved under the 2020 Plan.&lt;/p&gt;

 In connection with the transfer of employees to Tallac
 Therapeutics, Dr.&amp;#xA0;Hong Wan, the Company&amp;#x2019;s former Chief
 Scientific Officer, and eight of the Company&amp;#x2019;s employees, or
 Transferred Employees, terminated their employment with the Company
 effective as of June&amp;#xA0;30, 2020 and became employees of Tallac
 Therapeutics effective as of July&amp;#xA0;1, 2020. The options to
 purchase shares of the Company&amp;#x2019;s common stock that were
 previously granted to the Transferred Employees will continue to
 vest and be exercisable subject to the Transferred Employees
 remaining service providers under the original terms of the award.
 The Company evaluated the change in status from an employee to a
 consultant in accordance with ASC 718. While the Company concluded
 that the change in status did not affect the vesting condition or
 the classification of the initial awards, the significant reduction
 in the level of services that the grantees were expected to provide
 under the original awards as compared to the level of services
 expected under the Tallac Services Agreement will no longer meet
 the substantive service condition requirements and therefore the
 compensation cost for the unvested awards was recognized
 immediately with no future service requirement. The Company
 recorded $2.3&amp;#xA0;million in stock-based compensation expenses
 related to the modification for the three months ended
 June&amp;#xA0;30, 2020.&lt;/p&gt;

 In September 2020, in connection with the resignation of the
 Company&amp;#x2019;s former Chief Business Officer and the entry into a
 consulting agreement with him, the Company evaluated the change in
 status from an employee to a consultant in accordance with ASC 718.
 While the Company concluded that the change in status did not
 affect the vesting condition or the classification of the initial
 awards, the significant reduction in the level of services that the
 grantee was expected to provide under the original awards as
 compared to the level of services expected under the consulting
 agreement will no longer meet the substantive service condition
 requirements and therefore the compensation expense for the
 unvested awards expected to vest during the consultancy was
 recognized immediately with no future service requirement. The
 Company recorded $0.2&amp;#xA0;million in stock-based compensation
 expenses related to the modification for the three months ended
 September&amp;#xA0;30, 2020.&lt;/p&gt;

 These condensed consolidated financial statements have been
 prepared in accordance with accounting principles generally
 accepted in the United States of America, or U.S. GAAP, and the
 applicable rules and regulations of the U.S. Securities and
 Exchange Commission, or SEC, for interim reporting.&lt;/p&gt;

 The condensed consolidated balance sheet as of September&amp;#xA0;30,
 2020, the condensed consolidated statements of operations and
 comprehensive loss for the three and nine months ended
 September&amp;#xA0;30, 2019 and 2020, the condensed consolidated
 statements of convertible preferred stock and stockholders&amp;#x2019;
 equity (deficit) for the three and nine months ended
 September&amp;#xA0;30, 2019 and 2020, and the condensed consolidated
 statements of cash flows for the nine months ended
 September&amp;#xA0;30, 2019 and 2020, are unaudited. These unaudited
 condensed consolidated financial statements have been prepared on
 the same basis as the annual consolidated financial statements and,
 in the opinion of management, reflect all adjustments, which
 include only normal recurring adjustments, necessary to present
 fairly the Company&amp;#x2019;s financial position as of
 September&amp;#xA0;30, 2020, and its results of operations for the
 periods presented. The results of operations for the three and nine
 months ended September&amp;#xA0;30, 2020, are not necessarily
 indicative of the results to be expected for any subsequent
 periods, including the year ended December&amp;#xA0;31, 2020, and
 therefore should not be relied upon as an indicator of future
 results. The condensed consolidated balance sheet as of
 December&amp;#xA0;31, 2019 included herein was derived from the audited
 consolidated financial statements as of that date. The accompanying
 condensed consolidated financial statements and related notes
 should be read in conjunction with the audited consolidated
 financial statements for the year ended December&amp;#xA0;31, 2019 and
 the notes thereto, which are included in the Company&amp;#x2019;s final
 prospectus for the Company&amp;#x2019;s initial public offering filed
 pursuant to Rule 424(b)(4) under the Securities Act of 1933, as
 amended, with the SEC on July&amp;#xA0;17, 2020.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Reverse Stock Split&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 On July&amp;#xA0;8, 2020, the Company&amp;#x2019;s board of directors
 approved an amendment to the Company&amp;#x2019;s certificate of
 incorporation to effect a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;1-for-6.5806&lt;/font&gt;&lt;/font&gt; reverse split of
 its common stock and convertible preferred stock. The par values of
 the common and convertible preferred stock were not adjusted as a
 result of the reverse stock split. All authorized, issued and
 outstanding common stock, convertible preferred stock, stock
 options, warrants, and related per share amounts contained in the
 condensed consolidated financial statements have been retroactively
 adjusted to reflect this reverse stock split for all periods
 presented. The reverse stock split was effected on July&amp;#xA0;9,
 2020.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Use of Estimates&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The preparation of the condensed consolidated financial statements
 in conformity with U.S. GAAP requires management to make estimates
 and assumptions that affect the reported amounts of assets and
 liabilities and disclosure of contingent assets and liabilities at
 the date of the condensed consolidated financial statements and the
 reported amounts of revenues and expenses during the reporting
 periods. On an ongoing basis, management evaluates its estimates,
 including those related to the estimated useful lives of long-lived
 assets, clinical trial accruals, fair value of assets and
 liabilities, Series B convertible preferred stock warrant
 liability, term loan compound derivative liability, term loan,
 valuation of the Company&amp;#x2019;s common stock, income taxes and
 stock-based compensation. Management bases its estimates on
 historical experience and on various other market-specific and
 relevant assumptions that management believes to be reasonable
 under the circumstances. Actual results could differ from those
 estimates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Cash and Cash Equivalents&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company holds its cash and cash equivalents in checking and
 money market accounts. The Company considers all highly liquid
 investments with original maturities of three months or less from
 the date of purchase to be cash equivalents. Cash equivalents
 consist primarily of amounts invested in money market accounts and
 are stated at fair value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 4px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 0pt"&gt;
 &lt;b&gt;&lt;i&gt;Concentration of Credit Risk and Other Risks and
 Uncertainties&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Financial instruments that potentially subject the Company to a
 concentration of credit risk consist primarily of cash and cash
 equivalents. The Company maintains deposits in federally insured
 financial institutions in excess of federally insured limits, and
 invests in money market funds. The Company is exposed to credit
 risk in the event of default by the financial institutions holding
 its cash and cash equivalents. The Company has not experienced any
 losses on its deposits of cash and cash equivalents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s future results of operations involve a number
 of other risks and uncertainties. Factors that could affect the
 Company&amp;#x2019;s future operating results and cause actual results
 to vary materially from expectations include, but are not limited
 to, uncertainty of results of clinical trials and reaching
 milestones, uncertainty of regulatory approval of the
 Company&amp;#x2019;s potential product candidates, uncertainty of market
 acceptance of the Company&amp;#x2019;s product candidates, competition
 from substitute products and larger companies, securing and
 protecting proprietary technology, strategic relationships and
 dependence on key individuals or sole-source suppliers.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s product candidates require approvals from the
 U.S. Food and Drug Administration, or FDA, and comparable foreign
 regulatory agencies prior to commercial sales in their respective
 jurisdictions. There can be no assurance that any product
 candidates will receive the necessary approvals. If the Company was
 denied approval, approval was delayed or the Company was unable to
 maintain approval for any product candidate, it could have a
 materially adverse impact on the Company.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Property and Equipment&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Property and equipment are stated at cost less accumulated
 depreciation. Depreciation of property and equipment is provided
 using the straight-line method over the estimated useful lives of
 the assets. Upon sale or retirement of assets, the cost and related
 accumulated depreciation or amortization are removed from the
 condensed consolidated balance sheet and the resulting gain or loss
 is reflected in the condensed consolidated statement of operations
 and comprehensive loss. Maintenance and repairs are charged to the
 condensed consolidated statement of operations and comprehensive
 loss as incurred.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Deferred Offering Costs&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company capitalizes certain legal, professional accounting and
 other third-party fees that are directly associated with
 &lt;font style="WHITE-SPACE: nowrap"&gt;in-process&lt;/font&gt; equity
 financings as deferred offering costs until such financings are
 consummated. After consummation of the equity financing, these
 costs are recorded in stockholders&amp;#x2019; equity (deficit) as a
 reduction of additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital generated as a result
 of the equity financing.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Impairment of Long-Lived Assets&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company reviews property and equipment for impairment whenever
 events or changes in circumstances indicate that the carrying
 amount of an asset may not be recoverable. Recoverability is
 measured by comparison of the carrying amount to the future
 undiscounted net cash flows which the asset or asset group are
 expected to generate. If such assets are considered to be impaired,
 the impairment to be recognized is measured as the amount by which
 the carrying amount of the assets exceeds its fair value. Fair
 value is determined using various valuation techniques including
 discounted cash flow models, quoted market values and third-party
 independent appraisals, as considered necessary. There were no
 impairment charges recognized in the three and nine months ended
 September&amp;#xA0;30, 2019 and 2020.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Fair Value of Financial Instruments&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company applies fair value accounting for all financial assets
 and liabilities and nonfinancial assets and liabilities that are
 required to be recognized or disclosed at fair value in the
 condensed consolidated financial statements. The Company defines
 fair value as the price that would be received from selling an
 asset or paid to transfer a liability in an orderly transaction
 between market participants at the measurement date. Where
 observable prices or inputs are not available valuation models are
 applied. These valuation techniques involve some level of
 management estimation and judgment, the degree of which is
 dependent on the price transparency for the instruments or market
 and the instruments&amp;#x2019; complexity.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s financial instruments consist of cash and cash
 equivalents, receivables due from related-party, accounts payable,
 the term loan compound derivative liability and the Series B
 convertible preferred stock warrant liability. The term loan
 compound derivative liability and the Series B convertible
 preferred stock warrant liability are &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; at the end of every period
 and carried at fair value (Note 3). The recorded value of the
 Company&amp;#x2019;s receivables due from related-party and accounts
 payable approximates its current fair value due to the relatively
 short-term nature of these items.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Term Loan&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company accounts for the Loan and Security Agreement, dated as
 of December&amp;#xA0;20, 2019, as amended, with Silicon Valley Bank, or
 SVB, and WestRiver Innovation Lending Fund VIII, LP, or WestRiver,
 collectively as lenders, and SVB, as administrative agent and
 collateral agent, as a liability measured at net proceeds less debt
 discount and is accreted to the face value of the term loan over
 its expected term using the effective interest method. The Company
 considers whether there are any embedded features in its debt
 instruments that require bifurcation and separate accounting as
 derivative financial instruments pursuant to Accounting Standards
 Codification, or ASC, Topic 815, &lt;i&gt;Derivatives and
 Hedging&lt;/i&gt;.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Convertible Preferred Stock&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company records convertible preferred stock net of issuance
 costs on the dates of issuance, which represents the carrying
 value. In the event of a change of control of the Company, proceeds
 will be distributed in accordance with the liquidation preferences
 set forth in its organization documents unless the holders of
 convertible preferred stock have converted their convertible
 preferred stock into common stock. Convertible preferred stock are
 classified outside of stockholders&amp;#x2019; equity (deficit) on the
 accompanying condensed consolidated balance sheets as events
 triggering the liquidation preferences are not solely within the
 Company&amp;#x2019;s control. The Company has elected not to adjust the
 carrying values of the convertible preferred stock to the
 liquidation preferences of such shares because of the uncertainty
 of whether or when such an event would occur. Upon the consummation
 of the Company&amp;#x2019;s initial public offering in July 2020, all
 shares of convertible preferred stock outstanding and accrued

 &lt;b&gt;&lt;i&gt;Series B Convertible Preferred Stock Warrant
 Liability&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company has issued freestanding warrants to purchase its Series
 B convertible preferred stock. Freestanding warrants for the
 Company&amp;#x2019;s convertible preferred stock that are classified
 outside of permanent equity are recorded at fair value, and are
 subject to &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt;
 at the end of every period until the earlier of the exercise of the
 warrants or the completion of a liquidation event, including the
 completion of an initial public offering. Upon exercise, the Series
 B convertible preferred stock warrant liability would be
 reclassified to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital, with any change in
 fair value recognized as a component of other expense, net.
 Following the Company&amp;#x2019;s initial public offering, the warrants
 were automatically converted to warrants to purchase shares of
 common stock (Note 5). The Company revalued the Series B
 convertible preferred stock warrants as of the completion of the
 initial public offering and reclassified the outstanding preferred
 stock warrant liability balance to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital with no further
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt; required as
 common stock warrants are considered permanent equity.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Revenue Recognition&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 To date, the Company has derived revenue from providing research
 and development services on a time and materials basis to a
 related-party.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company recognizes such revenues over time as services are
 delivered, and invoices the customer as the work is incurred in
 arrears.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company recognizes revenue when its customer obtains control of
 promised goods or services, in an amount that reflects the
 consideration which the Company expects to receive in exchange for
 those goods or services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 To determine revenue recognition for arrangements that the Company
 determines are within the scope of Topic 606, the Company performs
 the following five steps: (i)&amp;#xA0;identify the contract(s) with a
 customer; (ii)&amp;#xA0;identify the performance obligations in the
 contract; (iii)&amp;#xA0;determine the transaction price;
 (iv)&amp;#xA0;allocate the transaction price to the performance
 obligations in the contract; and (v)&amp;#xA0;recognize revenue when
 (or as) the Company satisfies a performance obligation.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 As part of the Company&amp;#x2019;s consideration as to whether the
 Company has entered into a contract with a customer, it considers
 whether it is probable that it will collect the consideration it is
 entitled to in exchange for the goods and services it transfers to
 the customer. At contract inception, the Company assesses the goods
 or services promised within each contract that falls under the
 scope of Topic 606, determines those that are performance
 obligations, and assesses whether each promised good or service is
 distinct. The Company then recognizes as revenue the amount of the
 transaction price that is allocated to the respective performance
 obligation when (or as) the performance obligation is
 satisfied.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Cost of Services for Related-Party Revenue&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company incurs costs associated with related-party services
 including direct labor and associated employee benefits, laboratory
 supplies, and other expenses. These costs are recorded in cost of
 services for related-party revenue as a component of total
 operating expenses in the accompanying condensed consolidated
 statements of operations and comprehensive loss.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Research and Development Costs&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Research and development costs are expensed as incurred and consist
 primarily of salaries and benefits, stock-based compensation
 expense, lab supplies and facility costs, as well as fees paid to
 nonemployees and entities that conduct certain research and
 development activities on behalf of the Company and expenses
 incurred in connection with license agreements (Note 8).
 Nonrefundable advance payments for goods or services to be received
 in the future for use in research and development activities are
 capitalized and recorded in prepaid expenses and other current
 assets, and then expensed as the related goods are delivered or the
 services are performed.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Clinical and Manufacturing Accruals&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company records accruals for estimated costs of research,
 preclinical studies and clinical trials, and manufacturing
 development, which are a significant component of research and
 development expenses. A substantial portion of the Company&amp;#x2019;s
 ongoing research and development activities are conducted by
 third-party service providers, including contract research
 organizations, or CROs, and contract manufacturing organizations,
 or CMOs. The Company&amp;#x2019;s contracts with CROs generally include
 pass-through fees such as regulatory expenses, investigator fees,
 travel costs and other miscellaneous costs, including shipping and
 printing fees. The financial terms of these contracts are subject
 to negotiations, which vary from contract to contract and may
 result in payment flows that do not match the periods over which
 materials or services are provided to the Company under such
 contracts. The Company accrues the costs incurred under agreements
 with these third parties based on estimates of actual work
 completed in accordance with the respective agreements. The Company
 determines the estimated costs through discussions with internal
 personnel and external service providers as to the progress or
 stage of completion of the services and the agreed-upon fees to be
 paid for such services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company makes significant judgments and estimates in
 determining the accrual balance at the end of each reporting
 period. As actual costs become known, the Company adjusts its
 accruals. Although the Company does not expect its estimates to be
 materially different from amounts actually incurred, the
 Company&amp;#x2019;s understanding of the status and timing of services
 performed relative to the actual status and timing of services
 performed may vary and could result in the Company reporting
 amounts that are too high or too low in any particular period. To
 assist in its estimates the Company relies upon the receipt of
 timely and accurate reporting from its clinical and &lt;font style="WHITE-SPACE: nowrap"&gt;non-clinical&lt;/font&gt; studies and other
 third-party vendors. Through September&amp;#xA0;30, 2020, there have
 been no material differences from the Company&amp;#x2019;s accrued
 estimated expenses to the actual clinical trial expenses. However,
 variations in the assumptions used to estimate accruals, including,
 but not limited to, the number of patients enrolled, the rate of
 patient enrollment, and the actual services performed, and related
 costs may vary from the Company&amp;#x2019;s estimates, resulting in
 adjustments to clinical trial expense in future periods. Changes in
 these estimates that result in material changes to the
 Company&amp;#x2019;s accruals could materially affect its financial
 position and results of operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Stock-based Compensation Expense&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company accounts for stock-based compensation by measuring and
 recognizing compensation expense for all stock-based payments made
 to employees, directors and &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees&lt;/font&gt; based on estimated
 grant-date fair values. The Company uses the straight-line method
 to allocate compensation expense to reporting periods over each
 optionee&amp;#x2019;s requisite service period, which is generally the
 vesting period, and estimates the fair value of stock-based awards
 to employees and directors using the Black-Scholes option-pricing
 model. The Black-Scholes model requires the input of subjective
 assumptions, including expected volatility, expected dividend
 yield, expected term, risk-free rate of return and the estimated
 fair value of the underlying common stock on the date of grant. The
 Company accounts for the effect of forfeitures as they occur.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 4px"&gt;
 &amp;#xA0;&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Segment Reporting&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company manages its operations as a single operating segment
 for the purposes of assessing performance and making operating
 decisions.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Foreign Currency Transactions&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The functional currency of the Company&amp;#x2019;s operation and each
 of its subsidiaries is U.S. dollars. All assets and liabilities
 denominated in a foreign currency are translated into U.S. dollars
 at the exchange rate prevailing on the balance sheet date. Expenses
 are translated at the average exchange rates prevailing during the
 applicable period. Foreign currency transaction gains and losses
 are included in the consolidated statement of operations and
 comprehensive loss and recorded in other expense, net, and were
 immaterial for the three and nine months ended September&amp;#xA0;30,
 2019 and 2020, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Income Taxes&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company accounts for income taxes under the asset and liability
 method, which requires the recognition of deferred tax assets and
 liabilities for the expected future tax consequences of events that
 have been included in the condensed consolidated financial
 statements. Under this method, deferred tax assets and liabilities
 are determined on the basis of the differences between the
 condensed consolidated financial statement carrying amounts and tax
 bases of assets and liabilities using enacted tax rates in effect
 for the period in which the temporary differences are expected to
 reverse. The effect of a change in tax rates on deferred tax assets
 and liabilities is recognized in the condensed consolidated
 statements of operations and comprehensive loss in the period that
 includes the enactment date. The Company recognizes deferred tax
 assets to the extent that it believes these assets are more likely
 than not to be realized. In making such a determination, the
 Company considers all available positive and negative evidence,
 including future reversals of existing taxable temporary
 differences, projected future taxable income, &lt;font style="WHITE-SPACE: nowrap"&gt;tax-planning&lt;/font&gt; strategies and results of
 recent operations. If the Company determines that it would be able
 to realize its deferred tax assets in the future in excess of their
 net recorded amount, it would make an adjustment to the deferred
 tax asset valuation allowance, which would reduce the provision for
 income taxes. The Company recognizes benefits of uncertain tax
 positions if it is more likely than not that such positions will be
 sustained upon examination based solely on their technical merits,
 as the largest amount of benefit that is more likely than not to be
 realized upon the ultimate settlement. The Company&amp;#x2019;s policy
 is to recognize interest and penalties related to the underpayment
 of income taxes as a component of income tax expense or
 benefit.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Comprehensive Loss&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Comprehensive loss is equal to net loss for all periods
 presented.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 &lt;b&gt;&lt;i&gt;Net Loss Per Share Attributable to Common
 Stockholders&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Basic net loss per share is calculated by dividing the net loss
 attributable to common stockholders by the weighted-average number
 of shares of common stock outstanding during the period, without
 consideration for common stock equivalents. Diluted net loss per
 share is the same as basic net loss per share, since the effects of
 potentially dilutive securities are antidilutive given the net loss
 for each period presented.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company applies the &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method to compute basic and
 diluted net loss per share when it has issued shares that meet the
 definition of participating securities. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method determines net loss
 per share for each class of common stock and participating
 securities according to dividends declared or accumulated and
 participation rights in undistributed earnings. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method requires net loss
 available to common stockholders for the period to be allocated
 between common and participating securities based upon their
 respective rights to share in the earnings as if all net loss for
 the period had been distributed. The Company&amp;#x2019;s convertible
 preferred stock participate in any dividends declared by the
 Company and are therefore considered to be participating
 securities. The participating securities are not required to
 participate in the losses of the Company, and therefore during
 periods of loss there is no allocation required under the
 &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method.&lt;/p&gt;

 In February 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; (Topic 842),
 &lt;i&gt;Leases&lt;/i&gt; (ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02).&lt;/font&gt; ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; requires an entity to
 recognize assets and liabilities arising from a lease for both
 financing and operating leases. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; will also require new
 qualitative and quantitative disclosures to help investors and
 other financial statement users better understand the amount,
 timing, and uncertainty of cash flows arising from leases. In June
 2020, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2020-05,&lt;/font&gt; which extends the
 effective date of ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; for &lt;font style="WHITE-SPACE: nowrap"&gt;non-public&lt;/font&gt; business entities,
 including smaller reporting companies, to fiscal years beginning
 after December&amp;#xA0;15, 2021. The new standard is effective for the
 Company beginning January&amp;#xA0;1, 2022 (or earlier if the Company
 ceases to be an emerging growth company). Early adoption is
 permitted. The Company is currently evaluating the effects of the
 adoption of this guidance on its condensed consolidated financial
 statements and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In December 2019, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2019-12,&lt;/font&gt; Income Taxes (Topic
 740): Simplifying the Accounting for Income Taxes, which is
 intended to simplify various aspects related to accounting for
 income taxes. The pronouncement is effective for fiscal years, and
 for interim periods within those fiscal years, beginning after
 December&amp;#xA0;15, 2021. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2019-12&lt;/font&gt; is effective for the Company
 beginning January&amp;#xA0;1, 2022. Early adoption is permitted. The
 Company is currently in the process of evaluating the effects of
 the adoption of this guidance on the Company&amp;#x2019;s financial
 statements and does not expect it to have a material impact on its
 condensed consolidated financial statements.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;New Accounting Pronouncements Recently Adopted&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 In June 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-13,&lt;/font&gt; Financial
 Instruments-Credit Losses (Topic 326), which requires entities to
 measure all expected credit losses for financial assets held at the
 reporting date based on historical experience, current conditions,
 and reasonable and supportable forecasts. This replaces the
 existing incurred loss model and is applicable to the measurement
 of credit losses on financial assets measured at amortized cost.
 The Company early adopted this guidance on January&amp;#xA0;1, 2020.
 The adoption of this guidance did not have a material impact on the
 Company&amp;#x2019;s condensed consolidated financial statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In September 2018, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2018-13,&lt;/font&gt; Fair Value
 Measurement (Topic 820): Disclosure Framework&amp;#x2014;Changes to the
 Disclosure Requirements for Fair Value Measurement. The FASB issued
 final guidance that eliminates, adds and modifies certain
 disclosure requirements for fair value measurements as part of its
 disclosure framework project. Under the ASU, entities will no
 longer be required to disclose the amount of transfers between
 Level&amp;#xA0;1 and Level&amp;#xA0;2 of the fair value hierarchy. Public
 companies will be required to disclose changes in unrealized gains
 and losses for the period included in other comprehensive income
 for recurring Level&amp;#xA0;3 fair value measurements held at the end
 of the reporting period and the range and weighted average used to
 develop significant unobservable inputs for Level&amp;#xA0;3 fair value
 measurements. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2018-13&lt;/font&gt;
 is effective for public business entities for annual reporting
 periods, and interim periods within those annual periods, beginning
 after December&amp;#xA0;15, 2019, with early adoption permitted. The
 Company adopted this guidance on January&amp;#xA0;1, 2020. The adoption
 of ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2018-13&lt;/font&gt; did not
 have a material impact on its condensed consolidated financial
 statements.&lt;/p&gt;

 The Company holds its cash and cash equivalents in checking and
 money market accounts. The Company considers all highly liquid
 investments with original maturities of three months or less from
 the date of purchase to be cash equivalents. Cash equivalents
 consist primarily of amounts invested in money market accounts and
 are stated at fair value.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company accounts for the Loan and Security Agreement, dated as
 of December&amp;#xA0;20, 2019, as amended, with Silicon Valley Bank, or
 SVB, and WestRiver Innovation Lending Fund VIII, LP, or WestRiver,
 collectively as lenders, and SVB, as administrative agent and
 collateral agent, as a liability measured at net proceeds less debt
 discount and is accreted to the face value of the term loan over
 its expected term using the effective interest method. The Company
 considers whether there are any embedded features in its debt
 instruments that require bifurcation and separate accounting as
 derivative financial instruments pursuant to Accounting Standards
 Codification, or ASC, Topic 815, &lt;i&gt;Derivatives and
 Hedging&lt;/i&gt;.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company applies fair value accounting for all financial assets
 and liabilities and nonfinancial assets and liabilities that are
 required to be recognized or disclosed at fair value in the
 condensed consolidated financial statements. The Company defines
 fair value as the price that would be received from selling an
 asset or paid to transfer a liability in an orderly transaction
 between market participants at the measurement date. Where
 observable prices or inputs are not available valuation models are
 applied. These valuation techniques involve some level of
 management estimation and judgment, the degree of which is
 dependent on the price transparency for the instruments or market
 and the instruments&amp;#x2019; complexity.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s financial instruments consist of cash and cash
 equivalents, receivables due from related-party, accounts payable,
 the term loan compound derivative liability and the Series B
 convertible preferred stock warrant liability. The term loan
 compound derivative liability and the Series B convertible
 preferred stock warrant liability are &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; at the end of every period
 and carried at fair value (Note 3). The recorded value of the
 Company&amp;#x2019;s receivables due from related-party and accounts
 payable approximates its current fair value due to the relatively
 short-term nature of these items.&lt;/p&gt;

 basic net loss per share is the same as diluted net loss per share

 &lt;b&gt;(3) FAIR VALUE OF FINANCIAL INSTRUMENTS&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;
 The fair value of the Company&amp;#x2019;s financial assets and
 liabilities are determined in accordance with the fair value
 hierarchy established in ASC Topic 820, Fair Value Measurements and
 Disclosures. ASC Topic 820 defines fair value as the exchange price
 that would be received for an asset or paid to transfer a liability
 (an exit price) in the principal or most advantageous market for
 the asset or liability in an orderly transaction between market
 participants on the measurement date. The fair value hierarchy of
 ASC Topic 820 requires an entity to maximize the use of observable
 inputs when measuring fair value and classifies those inputs into
 three levels:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Level 1&amp;#x2014;Observable inputs, such as quoted prices in active
 markets&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Level 2&amp;#x2014;Inputs, other than the quoted prices in active
 markets, which are observable either directly or indirectly such as
 quoted prices for similar assets or liabilities; quoted prices in
 markets that are not active; or other inputs that are observable or
 can be corroborated by observable market data for substantially the
 full term of the instrument&amp;#x2019;s anticipated life&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Level 3&amp;#x2014;Unobservable inputs in which there is little or no
 market data, which require the reporting entity to develop its own
 assumptions&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s financial instruments consist of cash and cash
 equivalents, receivables due from related-party, accounts payable,
 the term loan compound derivative liability and the Series B
 convertible preferred stock warrant liability.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 9px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 0pt"&gt;
 Cash and cash equivalents are reported at their respective fair
 values on the Company&amp;#x2019;s condensed consolidated balance
 sheets. Where quoted prices are available in an active market,
 securities are classified as Level&amp;#xA0;1. The Company classifies
 money market funds as Level&amp;#xA0;1. When quoted market prices are
 not available for the specific security, then the Company estimates
 fair value by using quoted prices for identical or similar
 instruments in markets that are not active and model-based
 valuation techniques for which all significant inputs are
 observable in the market or can be corroborated by observable
 market data for substantially the full term of the assets. Where
 applicable, these models project future cash flows and discount the
 future amounts to a present value using market-based observable
 inputs obtained from various third-party data providers, including
 but not limited to benchmark yields, reported trades and
 broker/dealer quotes. Where applicable the market approach utilizes
 prices and information from market transactions for similar or
 identical assets.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company measures its Series B convertible preferred stock
 warrant liability and term loan compound derivative liability at
 fair value on a recurring basis and these are classified as
 Level&amp;#xA0;3 liabilities. The fair value of the Series B
 convertible preferred stock warrant liability was determined using
 an option-pricing model. The Company revalued the Series B
 convertible preferred stock warrants as of the completion of the
 initial public offering and reclassified the outstanding preferred
 stock warrant liability balance to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital with no further
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt; required as
 the common stock warrants are considered permanent equity effective
 with the completion of the initial public offering. The Company
 calculated the fair value of the term loan compound derivative
 liability by computing the difference between the fair value of the
 term loan with the compound derivative using the &amp;#x201C;with and
 without&amp;#x201D; method under the income approach, and the fair value
 of the term loan without the compound derivative. The valuation
 methodology and underlying assumptions are discussed further in
 Note 5.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 0pt"&gt;
 The Company did not have any outstanding financial assets or
 liabilities to be &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; on a recurring basis as of
 September&amp;#xA0;30, 2019.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 There were no transfers of assets or liabilities between the fair
 value measurement levels during the year ended December&amp;#xA0;31,
 2019 and the nine months ended September&amp;#xA0;30, 2020.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The carrying values of the Company&amp;#x2019;s financial instruments,
 such as accounts payable and accrued expenses and other current
 liabilities, approximate fair value due to the short-term nature of
 these items.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The estimated fair value of the Term Loan was $6.1&amp;#xA0;million as
 of September&amp;#xA0;30, 2020, which approximates the carrying value
 and is classified as Level&amp;#xA0;3. The Company utilized a market
 yield analysis and income approach to estimate a value for the Term
 Loan. The key valuation assumptions used consist of the discount
 rate of 12.0% and the probability of the occurrence of a change in
 control event of 20.0%.&lt;/p&gt;

 ALX Oncology Holdings Inc., or the Company, was formed as a
 Delaware corporation on April&amp;#xA0;1, 2020, or Inception. The
 Company was formed for the purpose of completing the
 Company&amp;#x2019;s initial public offering of its common stock and
 related transactions in order to carry on the business of ALX
 Oncology Limited. After Inception, ALX Oncology Limited became a
 wholly-owned subsidiary of the Company as a result of the internal
 reorganization. As part of the internal reorganization, all of the
 equity, option and warrant holders of ALX Oncology Limited became
 equity, option and warrant holders of the Company, holding the same
 number of corresponding shares, options and/or warrants in the
 Company as they did in ALX Oncology Limited immediately prior to
 the internal reorganization. The information included herein is
 presented as that of ALX Oncology Holdings Inc. unless such
 information refers to a date prior to April&amp;#xA0;1, 2020, in which
 case it will reflect that of ALX Oncology Limited, the predecessor
 company. The Company is a clinical-stage immuno-oncology company
 focused on helping patients fight cancer by developing therapies
 that block the CD47 checkpoint pathway and bridge the innate and
 adaptive immune system.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company owns subsidiaries, consisting of ALX Oncology Limited,
 incorporated in Ireland; ALX Oncology Inc., incorporated in the
 United States, and Alexo International Holdings Ltd, incorporated
 in Malta; Alexo Therapeutics International, incorporated in the
 Cayman Islands, which is a wholly-owned subsidiary of Alexo
 International Holdings Ltd. and Sirpant Therapeutics, incorporated
 in the Cayman Islands, which is a wholly-owned subsidiary of Alexo
 Therapeutics International, or collectively, the Subsidiaries.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 As of September&amp;#xA0;30, 2020, the Company has devoted
 substantially all of its efforts to the formation and financing of
 the Company, as well as product development, and has not realized
 product revenues from its planned principal operations. The Company
 has no manufacturing facilities and all manufacturing related
 activities are contracted out to third-party service providers.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In July 2020, the Company consummated its initial public offering
 and issued 9,775,000 shares of common stock for net proceeds of
 approximately $169.5&amp;#xA0;million, after deducting underwriting
 discounts and commissions of $13.0&amp;#xA0;million and
 offering-related expenses of $3.2&amp;#xA0;million. Upon the closing of
 the initial public offering, all shares of convertible preferred
 stock outstanding and accrued cumulative dividends were
 automatically converted into 23,934,533 shares of common stock.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 On July&amp;#xA0;21, 2020, the Company&amp;#x2019;s amended and restated
 certificate of incorporation became effective, authorizing
 1,000,000,000 shares of common stock and 100,000,000 shares of
 undesignated preferred stock.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 As of September&amp;#xA0;30, 2020, the Company had cash and cash
 equivalents of $259.5&amp;#xA0;million, which will be sufficient to
 fund its planned operations for a period of at least twelve months
 following the issuance of these condensed consolidated financial
 statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 Management expects to incur additional losses in the future to
 conduct product candidate research and development and to conduct
 &lt;font style="WHITE-SPACE: nowrap"&gt;pre-commercialization&lt;/font&gt;
 activities and recognizes the need to raise additional capital to
 fully implement its business plan. The Company intends to raise
 such capital through the sale of additional equity, debt financings
 or strategic alliances with third parties. However, there can be no
 assurance that the Company will be successful in acquiring
 additional funding at levels sufficient to fund its operations or
 on terms acceptable to the Company. If the Company is unsuccessful
 in its efforts to raise additional financing, the Company could be
 required to significantly reduce operating expenses and delay,
 reduce the scope of or eliminate some of its development programs
 or its future commercialization efforts, &lt;font style="WHITE-SPACE: nowrap"&gt;out-license&lt;/font&gt; intellectual property
 rights to its product candidates and sell unsecured assets, or a
 combination of the above, any of which may have a material adverse
 effect on the Company&amp;#x2019;s business, results of operations,
 financial condition and/or its ability to fund its scheduled
 obligations on a timely basis or at all.&lt;/p&gt;

 &lt;i&gt;Related-party revenue&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 In June 2018, the Company entered into a Research and Development
 Services Agreement, or Tollnine Agreement, with Tollnine, a
 related-party of the Company, to provide research and development
 services to Tollnine. The Company&amp;#x2019;s Chief Executive Officer
 was also the Chief Executive Officer of Tollnine until April 2020
 and two of the Company&amp;#x2019;s investors are also investors in
 Tollnine. As such, Tollnine was deemed to be a related-party. The
 Tollnine Agreement has an initial term of 3 years, to be
 automatically renewed for additional &lt;font style="WHITE-SPACE: nowrap"&gt;one-year&lt;/font&gt; terms unless terminated by
 either party. The services are to be provided at a price based on
 the costs incurred by the Company plus a &lt;font style="WHITE-SPACE: nowrap"&gt;mark-up&lt;/font&gt; equal to 10% of such costs.
 The Company recognizes revenue when Tollnine, as the
 Company&amp;#x2019;s customer, obtains control of promised goods or
 services, in an amount that reflects the consideration which the
 Company expects to receive in exchange for those goods or services.
 The Company recognized related-party revenues of $1.3&amp;#xA0;million
 and zero for the three months ended September&amp;#xA0;30, 2019 and
 2020, respectively, and $3.6&amp;#xA0;million and $1.2&amp;#xA0;million for
 the nine months ended September&amp;#xA0;30, 2019 and 2020,
 respectively, under the Tollnine Agreement. Effective as of
 July&amp;#xA0;1, 2020, the Company terminated the Tollnine Agreement
 and entered into the Tallac Services Agreement with Tallac
 Therapeutics.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 As of December&amp;#xA0;31, 2019 and September&amp;#xA0;30, 2020, the
 Company had outstanding related-party receivables from Tollnine of
 $0.5&amp;#xA0;million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 4pt"&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company entered into a research and development services
 agreement, or the Tallac Services Agreement, with Tallac
 Therapeutics effective as of July&amp;#xA0;1, 2020. The Tallac Services
 Agreement provides that Tallac Therapeutics will provide certain
 preclinical research services to the Company for a service fee
 based on the costs incurred by Tallac Therapeutics plus a
 &lt;font style="WHITE-SPACE: nowrap"&gt;mark-up&lt;/font&gt; equal to 10.0% of
 such costs. The Tallac Services Agreement has an initial term of
 four years and is renewed automatically for additional one year
 terms thereafter. The Company records the payments for the research
 and development services as research and development costs within
 the condensed consolidated statement of operations and
 comprehensive loss. The Company has recorded $0.4&amp;#xA0;million as
 research and development costs for the three months ended
 September&amp;#xA0;30, 2020.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Concentration of Credit Risk and Other Risks and

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 Financial instruments that potentially subject the Company to a
 concentration of credit risk consist primarily of cash and cash
 equivalents. The Company maintains deposits in federally insured
 financial institutions in excess of federally insured limits, and
 invests in money market funds. The Company is exposed to credit
 risk in the event of default by the financial institutions holding
 its cash and cash equivalents. The Company has not experienced any
 losses on its deposits of cash and cash equivalents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s future results of operations involve a number
 of other risks and uncertainties. Factors that could affect the
 Company&amp;#x2019;s future operating results and cause actual results
 to vary materially from expectations include, but are not limited
 to, uncertainty of results of clinical trials and reaching
 milestones, uncertainty of regulatory approval of the
 Company&amp;#x2019;s potential product candidates, uncertainty of market
 acceptance of the Company&amp;#x2019;s product candidates, competition
 from substitute products and larger companies, securing and
 protecting proprietary technology, strategic relationships and
 dependence on key individuals or sole-source suppliers.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s product candidates require approvals from the
 U.S. Food and Drug Administration, or FDA, and comparable foreign
 regulatory agencies prior to commercial sales in their respective
 jurisdictions. There can be no assurance that any product
 candidates will receive the necessary approvals. If the Company was
 denied approval, approval was delayed or the Company was unable to
 maintain approval for any product candidate, it could have a
 materially adverse impact on the Company.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company capitalizes certain legal, professional accounting and
 other third-party fees that are directly associated with
 &lt;font style="WHITE-SPACE: nowrap"&gt;in-process&lt;/font&gt; equity
 financings as deferred offering costs until such financings are
 consummated. After consummation of the equity financing, these
 costs are recorded in stockholders&amp;#x2019; equity (deficit) as a
 reduction of additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital generated as a result
 of the equity financing.&lt;/p&gt;

 On July&amp;#xA0;8, 2020, the Company&amp;#x2019;s board of directors
 approved an amendment to the Company&amp;#x2019;s certificate of
 incorporation to effect a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;1-for-6.5806&lt;/font&gt;&lt;/font&gt; reverse split of
 its common stock and convertible preferred stock. The par values of
 the common and convertible preferred stock were not adjusted as a
 result of the reverse stock split. All authorized, issued and
 outstanding common stock, convertible preferred stock, stock
 options, warrants, and related per share amounts contained in the
 condensed consolidated financial statements have been retroactively
 adjusted to reflect this reverse stock split for all periods
 presented. The reverse stock split was effected on July&amp;#xA0;9,
 2020.&lt;/p&gt;

 In February 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; (Topic 842),
 &lt;i&gt;Leases&lt;/i&gt; (ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02).&lt;/font&gt; ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; requires an entity to
 recognize assets and liabilities arising from a lease for both
 financing and operating leases. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; will also require new
 qualitative and quantitative disclosures to help investors and
 other financial statement users better understand the amount,
 timing, and uncertainty of cash flows arising from leases. In June
 2020, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2020-05,&lt;/font&gt; which extends the
 effective date of ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; for &lt;font style="WHITE-SPACE: nowrap"&gt;non-public&lt;/font&gt; business entities,
 including smaller reporting companies, to fiscal years beginning
 after December&amp;#xA0;15, 2021. The new standard is effective for the
 Company beginning January&amp;#xA0;1, 2022 (or earlier if the Company
 ceases to be an emerging growth company). Early adoption is
 permitted. The Company is currently evaluating the effects of the
 adoption of this guidance on its condensed consolidated financial
 statements and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 In December 2019, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2019-12,&lt;/font&gt; Income Taxes (Topic
 740): Simplifying the Accounting for Income Taxes, which is
 intended to simplify various aspects related to accounting for
 income taxes. The pronouncement is effective for fiscal years, and
 for interim periods within those fiscal years, beginning after
 December&amp;#xA0;15, 2021. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2019-12&lt;/font&gt; is effective for the Company
 beginning January&amp;#xA0;1, 2022. Early adoption is permitted. The
 Company is currently in the process of evaluating the effects of
 the adoption of this guidance on the Company&amp;#x2019;s financial
 statements and does not expect it to have a material impact on its
 condensed consolidated financial statements.&lt;/p&gt;

 The condensed consolidated balance sheet as of September&amp;#xA0;30,
 2020, the condensed consolidated statements of operations and
 comprehensive loss for the three and nine months ended
 September&amp;#xA0;30, 2019 and 2020, the condensed consolidated
 statements of convertible preferred stock and stockholders&amp;#x2019;
 equity (deficit) for the three and nine months ended
 September&amp;#xA0;30, 2019 and 2020, and the condensed consolidated
 statements of cash flows for the nine months ended
 September&amp;#xA0;30, 2019 and 2020, are unaudited. These unaudited
 condensed consolidated financial statements have been prepared on
 the same basis as the annual consolidated financial statements and,
 in the opinion of management, reflect all adjustments, which
 include only normal recurring adjustments, necessary to present
 fairly the Company&amp;#x2019;s financial position as of
 September&amp;#xA0;30, 2020, and its results of operations for the
 periods presented. The results of operations for the three and nine
 months ended September&amp;#xA0;30, 2020, are not necessarily
 indicative of the results to be expected for any subsequent
 periods, including the year ended December&amp;#xA0;31, 2020, and
 therefore should not be relied upon as an indicator of future
 results. The condensed consolidated balance sheet as of
 December&amp;#xA0;31, 2019 included herein was derived from the audited
 consolidated financial statements as of that date. The accompanying
 condensed consolidated financial statements and related notes
 should be read in conjunction with the audited consolidated
 financial statements for the year ended December&amp;#xA0;31, 2019 and
 the notes thereto, which are included in the Company&amp;#x2019;s final
 prospectus for the Company&amp;#x2019;s initial public offering filed
 pursuant to Rule 424(b)(4) under the Securities Act of 1933, as
 amended, with the SEC on July&amp;#xA0;17, 2020.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Clinical and Manufacturing Accruals&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company records accruals for estimated costs of research,
 preclinical studies and clinical trials, and manufacturing
 development, which are a significant component of research and
 development expenses. A substantial portion of the Company&amp;#x2019;s
 ongoing research and development activities are conducted by
 third-party service providers, including contract research
 organizations, or CROs, and contract manufacturing organizations,
 or CMOs. The Company&amp;#x2019;s contracts with CROs generally include
 pass-through fees such as regulatory expenses, investigator fees,
 travel costs and other miscellaneous costs, including shipping and
 printing fees. The financial terms of these contracts are subject
 to negotiations, which vary from contract to contract and may
 result in payment flows that do not match the periods over which
 materials or services are provided to the Company under such
 contracts. The Company accrues the costs incurred under agreements
 with these third parties based on estimates of actual work
 completed in accordance with the respective agreements. The Company
 determines the estimated costs through discussions with internal
 personnel and external service providers as to the progress or
 stage of completion of the services and the agreed-upon fees to be
 paid for such services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 9pt"&gt;
 The Company makes significant judgments and estimates in
 determining the accrual balance at the end of each reporting
 period. As actual costs become known, the Company adjusts its
 accruals. Although the Company does not expect its estimates to be
 materially different from amounts actually incurred, the
 Company&amp;#x2019;s understanding of the status and timing of services
 performed relative to the actual status and timing of services
 performed may vary and could result in the Company reporting
 amounts that are too high or too low in any particular period. To
 assist in its estimates the Company relies upon the receipt of
 timely and accurate reporting from its clinical and &lt;font style="WHITE-SPACE: nowrap"&gt;non-clinical&lt;/font&gt; studies and other
 third-party vendors. Through September&amp;#xA0;30, 2020, there have
 been no material differences from the Company&amp;#x2019;s accrued
 estimated expenses to the actual clinical trial expenses. However,
 variations in the assumptions used to estimate accruals, including,
 but not limited to, the number of patients enrolled, the rate of
 patient enrollment, and the actual services performed, and related
 costs may vary from the Company&amp;#x2019;s estimates, resulting in
 adjustments to clinical trial expense in future periods. Changes in
 these estimates that result in material changes to the
 Company&amp;#x2019;s accruals could materially affect its financial
 position and results of operations.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Series B Convertible Preferred Stock Warrant
 Liability&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-TOP: 2pt"&gt;
 The Company has issued freestanding warrants to purchase its Series
 B convertible preferred stock. Freestanding warrants for the
 Company&amp;#x2019;s convertible preferred stock that are classified
 outside of permanent equity are recorded at fair value, and are
 subject to &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt;
 at the end of every period until the earlier of the exercise of the
 warrants or the completion of a liquidation event, including the
 completion of an initial public offering. Upon exercise, the Series
 B convertible preferred stock warrant liability would be
 reclassified to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital, with any change in
 fair value recognized as a component of other expense, net.
 Following the Company&amp;#x2019;s initial public offering, the warrants
 were automatically converted to warrants to purchase shares of
 common stock (Note 5). The Company revalued the Series B
 convertible preferred stock warrants as of the completion of the
 initial public offering and reclassified the outstanding preferred
 stock warrant liability balance to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital with no further
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt; required as
 common stock warrants are considered permanent equity.&lt;/p&gt;

 The Company has issued freestanding warrants to purchase its Series
 B convertible preferred shares. Freestanding warrants for the
 Company&amp;#x2019;s convertible preferred shares that are classified

 subject to &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt;

 warrants or the completion of a liquidation event. Upon exercise,
 the Series B convertible preferred shares warrant liability would
 be reclassified to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital, with any change in
 fair value recognized as a component of other income (expense),

 &lt;b&gt;Net Loss Per Share Attributable to Ordinary Shareholders&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 Basic net loss per share is calculated by dividing the net loss
 attributable to ordinary shareholders by the weighted-average
 number of ordinary shares outstanding during the period, without
 consideration for ordinary share equivalents. Net loss attributable
 to ordinary shareholders is calculated by adjusting net loss of the
 Company for cumulative preferred share dividends. Diluted net loss
 per share is the same as basic net loss per share, since the
 effects of potentially dilutive securities are antidilutive given
 the net loss for each period presented.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company applies the &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method to compute basic and
 diluted net loss per share when it has issued shares that meet the
 definition of participating securities. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method determines net loss
 per share for each class of ordinary and participating securities
 according to dividends declared or accumulated and participation
 rights in undistributed earnings. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method requires net loss
 available to ordinary shareholders for the period to be allocated
 between ordinary and participating securities based upon their
 respective rights to share in the earnings as if all net loss for
 the period had been distributed. The Company&amp;#x2019;s convertible
 preferred shares participate in any dividends declared by the
 Company and are therefore considered to be participating
 securities. The participating securities are not required to
 participate in the losses of the Company, and therefore during
 periods of loss there is no allocation required under the
 &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method.&lt;/p&gt;

 &lt;b&gt;Unaudited Pro Forma Net Loss Per Share Attributable to Ordinary
 Shareholders&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 In contemplation of an initial public offering, or IPO, the Company
 has presented unaudited pro forma basic and diluted net loss per
 share attributable to ordinary shareholders for the year ended
 December&amp;#xA0;31, 2019. Unaudited pro forma basic net loss per
 share attributable to ordinary shareholders as of December&amp;#xA0;31,
 2019 is computed to give effect to adjustments to the denominator
 in the pro forma basic and diluted net loss per share calculation
 to reflect the conversion of all of the Company&amp;#x2019;s outstanding
 convertible preferred shares and cumulative dividends into
 11,253,839 ordinary shares, as if the conversion had occurred as of
 the beginning of the period or the original date of issuance, if
 later.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Unaudited pro forma diluted net loss attributable to ordinary
 shareholders is the same as unaudited pro forma basic net loss per
 share attributable to ordinary shareholders for the period as the
 impact of any potentially dilutive securities was anti-dilutive,
 which has been computed to give effect to the adjustment noted
 above. The pro forma net loss per share attributable to ordinary
 shareholders does not include proceeds to be received from nor does
 it include shares expected to be sold in the assumed IPO.&lt;/p&gt;

 In 2015, in conjunction with the founding of the Company, 2,127,460
 ordinary shares were issued to the founders, or Founder Stock, at a
 price of $0.033 per share. These shares are subject to repurchase
 at the option of the Company at a price that is the lower of
 (i)&amp;#xA0;the original issuance price or (ii)&amp;#xA0;the fair market
 value as of the date of repurchase, in the event that the
 founders&amp;#x2019; employment is terminated either voluntarily or
 involuntarily. Such repurchase rights generally lapse over a period
 of four years from the date the Founder Stock was issued. As of
 December&amp;#xA0;31, 2018, and December&amp;#xA0;31, 2019, there were
 113,864 and no founder shares subject to repurchase, respectively.

 Series A Investors. Under the terms of the Series A Agreement, the
 Company authorized the sale and issuance of up to 5,470,625 of the
 Company&amp;#x2019;s Series A convertible preferred shares. The purchase
 and sale of the Series A convertible preferred shares could be sold
 in one or more closings in accordance with the Series A Agreement.
 In March 2017, the Company entered into a convertible promissory
 note purchase agreement, or the Note Purchase Agreement, with
 certain existing investors, employees and new investors, or
 collectively, the Promissory Note Investors. Under the terms of the
 Note Purchase Agreement, the Company issued promissory notes in the
 aggregate principal amount of $25.0&amp;#xA0;million that are
 convertible into Series A convertible preferred shares to the
 Promissory Note Investors.&lt;/p&gt;

 In 2015 and 2016, the Company issued a total of 5,470,612 Series A
 convertible preferred shares to investors at $6.58 per share for
 cash proceeds of $34.8&amp;#xA0;million. In September 2017, the Company
 issued a total of 3,826,469 Series A convertible preferred shares
 for cash proceeds of $1.2&amp;#xA0;million pursuant to the conversion
 of outstanding convertible promissory notes. The gross proceeds of
 $37.2&amp;#xA0;million were reduced by total issuance costs incurred of
 $0.2&amp;#xA0;million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In May 2019, the Company entered into a Series B Preferred Share
 Purchase Agreement or the Series B Agreement, with certain existing
 investors, employees and new investors, or collectively, the Series
 B Investors. Under the terms of the Series B Agreement, the Company
 authorized the sale and issuance of up to 2,145,370 of the
 Company&amp;#x2019;s Series B convertible preferred shares at a purchase
 price of $9.4972 per share. The purchase and sale of the Series B
 convertible preferred shares could be sold in one or more closings
 in accordance with the Series B Agreement. As of December&amp;#xA0;31,
 2019, a total of 1,016,727 shares had been purchased with gross
 proceeds of $9.6&amp;#xA0;million. The gross proceeds of
 $9.6&amp;#xA0;million were reduced by total issuance costs incurred of
 $0.2&amp;#xA0;million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The rights, preferences and privileges of the Series A and Series B
 convertible preferred shares, or Preferred Shares, as of
 December&amp;#xA0;31, 2019 are as follows:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Dividend Provisions&lt;/i&gt; &amp;#x2013; Cumulative dividends of 6.0% per
 annum of the original issue price for each Preferred Shares series
 are payable when and as declared by the Company&amp;#x2019;s Board of
 Directors, or Board of Directors, upon the occurrence of a
 liquidation event or upon a contingent mandatory conversion of the
 Preferred Shares in connection with a qualified initial public
 offering as described below. The Series A original issue price is
 $6.58, and the Series B original issue price is $9.4972. The
 original issue price is subject to adjustment in the event of any
 share dividend, share split, combination, consolidation or other
 recapitalization. The dividends shall accrue from day to day from
 the issue date of such Preferred Shares whether or not declared and
 shall be cumulative. In addition, the Preferred Shares participate
 on an &lt;font style="WHITE-SPACE: nowrap"&gt;as-converted&lt;/font&gt; basis
 in any dividends payable to ordinary shareholders. Cumulative
 dividends for the years ended December&amp;#xA0;31, 2018 and
 December&amp;#xA0;31, 2019 was $8.7&amp;#xA0;million and
 $12.7&amp;#xA0;million, respectively. No dividends have been declared
 or paid since the issuance of convertible preferred shares through
 December&amp;#xA0;31, 2019.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Liquidation&lt;/i&gt; &amp;#x2013; In the event of liquidation, dissolution
 or winding up of the Company, merger or a reduction of capital
 through the sale or lease of all or substantial part of the
 business of the Company, before any distribution or payment shall
 be made to the holders of ordinary shares, the holders of Preferred
 Shares shall be entitled to be paid an amount in cash equal to the
 original issue price (subject to adjustment in the event of any
 share dividend, share split, combination, or other
 recapitalization) plus all dividends accumulated and unpaid
 thereon. First, the holders of the Preferred Shares are paid in
 full the amounts specified in the immediately preceding sentence on
 a &lt;font style="WHITE-SPACE: nowrap"&gt;pro-rata&lt;/font&gt; basis; then,
 after holders of the Preferred Shares are satisfied, any remaining
 amounts shall be distributed on a &lt;font style="WHITE-SPACE: nowrap"&gt;pro-rata&lt;/font&gt; basis to the holders of the
 Preferred Shares (calculated on an as converted basis) and the
 ordinary shares.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Voting Rights&lt;/i&gt; &amp;#x2013; On any matter presented to the
 shareholders of the Company, each holder of outstanding Preferred
 Shares shall be entitledto cast the number of votes equal to the
 number of whole ordinary shares into which the Preferred Shares
 held by such holder are convertible. The holders of Preferred
 Shares shall vote together with the holders of ordinary shares as a
 single class. Additionally, as long as at least 1,367,656 Preferred
 Shares are outstanding (subject to adjustment in the event of any
 recapitalizations), the Company must receive approval of holders of
 at least &lt;font style="WHITE-SPACE: nowrap"&gt;two-third&lt;/font&gt; of the
 voting rights then held in aggregate by the holders of the
 Preferred Shares in issue on an &lt;font style="WHITE-SPACE: nowrap"&gt;as-converted&lt;/font&gt; basis in order to effect
 certain corporate actions. Two investors have contractual rights to
 elect three out of five board members.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Optional Conversion at Holders&amp;#x2019; Option&lt;/i&gt; &amp;#x2013; Each
 share of Preferred Shares shall be convertible, at the option of
 the holder, at any time and from time to time, into such number of
 fully paid and &lt;font style="WHITE-SPACE: nowrap"&gt;non-assessable&lt;/font&gt; ordinary shares as is
 determined by dividing the original issue price by the Applicable
 Conversion Price. The Applicable Conversion Price for each series
 of Preferred Shares is currently equal to the original issue price
 for such series. Upon conversion, the holders shall also receive
 only declared but as yet unpaid dividends. Note only holders of
 Preferred Shares receive declared and unpaid dividends; preferred
 shareholders who chose to convert prior to the declaration of such
 dividends are not entitled to receive accumulated dividends.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 9px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt"&gt;
 &lt;i&gt;Contingent Mandatory Conversion&lt;/i&gt; &amp;#x2013; Upon the closing of
 the first underwritten public offering pursuant to an effective
 registration statement under the Securities Act of 1933, as
 amended, or pursuant to a corresponding securities issuance
 application process in any &lt;font style="WHITE-SPACE: nowrap"&gt;non-U.S.&lt;/font&gt; jurisdiction, covering the
 offer and sale of the Company&amp;#x2019;s ordinary shares in which
 (i)&amp;#xA0;the per share price is not less than $15.19540 (as
 adjusted for any share dividends, combinations, splits,
 recapitalizations and the like with respect to such shares after
 the filing date hereof) and (ii)&amp;#xA0;the gross cash proceeds to
 the Company (before underwriting discounts, commissions and fees)
 are at least $50.0&amp;#xA0;million then all outstanding Preferred
 Shares shall automatically be converted into a number of ordinary
 shares, at a conversion rate determined by dividing the applicable
 original price of such Preferred Shares by the applicable
 conversion price of such Preferred Shares. Upon conversion, the
 holders shall also receive any cumulative and unpaid dividends,
 whether or not declared as conversion ordinary shares at the same
 conversion rate for the applicable Preferred Shares.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Down-Round Antidilution Protection&lt;/i&gt; &amp;#x2013; In the event the
 Company issues its ordinary shares without consideration or for
 consideration pershare that is less than the conversion price in
 effect for each series of the Preferred Shares, then the conversion
 price for that series shall be reduced in order to increase the
 number of ordinary shares into which such series of Preferred
 Shares is convertible to.&lt;/p&gt;

 Alexo Therapeutics Limited, or the Company, was initially
 incorporated in Ireland on March&amp;#xA0;13, 2015 and changed its name
 to ALX Oncology Limited on October&amp;#xA0;11, 2018. The Company is a
 clinical-stage immuno-oncology company focused on helping patients
 fight cancer by developing therapies that block the CD47 checkpoint
 pathway and bridge the innate and adaptive immune system.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company owns a direct subsidiary, ALX Oncology Inc.,
 incorporated in the United States, as well as a direct subsidiary
 incorporated in Malta, Alexo International Holdings Ltd. The
 Company also has two indirect subsidiaries, Alexo Therapeutics
 International, incorporated in the Cayman Islands, which is a
 wholly-owned subsidiary of Alexo International Holdings Ltd. and
 Sirpant Therapeutics, incorporated in the Cayman Islands, which is
 a wholly-owned subsidiary of Alexo Therapeutics International,
 collectively, the Subsidiaries.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company completed an internal reorganization transaction in
 April 2020, pursuant to which ALX Oncology Limited became a
 wholly-owned subsidiary of ALX Oncology Holdings Inc., a newly
 formed Delaware corporation. As part of the transaction, all of the
 equity, option and warrant holders of ALX Oncology Limited became
 equity, option and warrant holders of ALX Oncology Holdings Inc.,
 holding the same number of corresponding shares, options and/or
 warrants in ALX Oncology Holdings Inc., as they did in the Company
 immediately prior to the reorganization (Note 13).&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 These consolidated financial statements have been prepared in
 accordance with accounting principles generally accepted in the
 United States of America, or U.S. GAAP.&lt;/p&gt;

 &lt;b&gt;Principles of Consolidation&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 All intercompany balances and transactions have been eliminated in

 Immediately prior to the completion of this offering, all
 outstanding convertible preferred shares will automatically convert
 into ordinary shares. Unaudited pro forma basic and diluted net
 loss per share has been computed to give effect to the conversion
 of all outstanding convertible preferred shares and cumulative
 dividends on the convertible preferred shares into ordinary shares.
 The unaudited pro forma net loss per share does not include the
 shares expected to be sold and related proceeds to be received from
 the initial public offering.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Need for Additional Capital&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 Since commencing operations, none of the Company&amp;#x2019;s product
 candidates have received marketing approval from the U.S. Food and
 Drug Administration, or FDA, or any other federal, state, local or
 foreign governmental or regulatory authority and therefore the
 Company has not generated any revenue from drug product sales. The
 Company had an accumulated deficit of $72.8&amp;#xA0;million as of
 December&amp;#xA0;31, 2019 and management does not expect to experience
 positive cash flows in the foreseeable future. Based on
 management&amp;#x2019;s current plans, management believes cash of
 $9.0&amp;#xA0;million as of December&amp;#xA0;31, 2019, along with the
 $105.0&amp;#xA0;million of gross proceeds from the issuance of Series C
 convertible preferred shares in February 2020 (Note 13), are
 sufficient to fund operations through at least one year from the
 date of the issuance of these consolidated financial
 statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Management expects to incur additional losses in the future to
 conduct product candidate research and development and to conduct
 &lt;font style="WHITE-SPACE: nowrap"&gt;pre-commercialization&lt;/font&gt;
 activities and recognizes the need to raise additional capital to
 fully implement its business plan. The Company intends to raise
 such capital through the sale of additional equity, debt financings
 or strategic alliances with third parties. However, there can be no
 assurance that the Company will be successful in acquiring
 additional funding at levels sufficient to fund its operations or
 on terms acceptable to the Company. If the Company is unsuccessful
 in its efforts to raise additional financing, the Company could be
 required to significantly reduce operating expenses and delay,
 reduce the scope of or eliminate some of its development programs
 or its future commercialization efforts, &lt;font style="WHITE-SPACE: nowrap"&gt;out-license&lt;/font&gt; intellectual property
 rights to its product candidates and sell unsecured assets, or a
 combination of the above, any of which may have a material adverse
 effect on the Company&amp;#x2019;s business, results of operations,
 financial condition and/or its ability to fund its scheduled
 obligations on a timely basis or at all.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Use of Estimates&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The preparation of consolidated financial statements in conformity
 with U.S. GAAP requires management to make estimates and
 assumptions that affect the reported amounts of assets and
 liabilities and disclosure of contingent assets and liabilities at
 the date of the consolidated financial statements and the reported
 amounts of revenues and expenses during the reporting periods. On
 an ongoing basis, management evaluates its estimates, including
 those related to the estimated useful lives of long-lived assets,
 clinical trial accruals, fair value of assets and liabilities,
 Series B convertible preferred shares warrant liability, term loan
 compound derivative liability, term loan, valuation of ordinary
 shares, income taxes and share-based compensation. Management bases
 its estimates on historical experience and on various other
 market-specific and relevant assumptions that management believes
 to be reasonable under the circumstances. Actual results could
 differ from those estimates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Cash&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company holds its cash in checking and interest-bearing
 accounts.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Concentration of Credit Risk and Other Risks and
 Uncertainties&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 Financial instruments that potentially subject the Company to a
 concentration of credit risk consist primarily of cash. The Company
 maintains deposits in federally insured financial institutions in
 excess of federally insured limits. The Company is exposed to
 credit risk in the event of default by the financial institutions
 holding its cash. The Company has not experienced any losses on its
 deposits of cash.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s future results of operations involve a number
 of other risks and uncertainties. Factors that could affect the
 Company&amp;#x2019;s future operating results and cause actual results
 to vary materially from expectations include, but are not limited
 to, uncertainty of results of clinical trials and reaching
 milestones, uncertainty of regulatory approval of the
 Company&amp;#x2019;s potential product candidates, uncertainty of market
 acceptance of the Company&amp;#x2019;s product candidates, competition
 from substitute products and larger companies, securing and
 protecting proprietary technology, strategic relationships and
 dependence on key individuals or sole-source suppliers.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s product candidates require approvals from the
 FDA and comparable foreign regulatory agencies prior to commercial
 sales in their respective jurisdictions. There can be no assurance
 that any product candidates will receive the necessary approvals.
 If the Company was denied approval, approval was delayed or the
 Company was unable to maintain approval for any product candidate,
 it could have a materially adverse impact on the Company.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Property and Equipment&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 Property and equipment are stated at cost less accumulated
 depreciation. Depreciation of property and equipment is provided
 using the straight-line method over the estimated useful lives of
 the assets (Note 3). Upon sale or retirement of assets, the cost
 and related accumulated depreciation or amortization are removed
 from the consolidated balance sheet and the resulting gain or loss
 is reflected in the consolidated statement of operations and
 comprehensive loss. Maintenance and repairs are charged to the
 consolidated statement of operations and comprehensive loss as
 incurred.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The useful lives of the property and equipment are as follows:&lt;/p&gt;

 &lt;b&gt;Impairment of Long-Lived Assets&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company reviews property and equipment for impairment whenever
 events or changes in circumstances indicate that the carrying
 amount of an asset may not be recoverable. Recoverability is
 measured by comparison of the carrying amount to the future
 undiscounted net cash flows which the asset or asset group are
 expected to generate. If such assets are considered to be impaired,
 the impairment to be recognized is measured as the amount by which
 the carrying amount of the assets exceeds its fair value. Fair
 value is determined using various valuation techniques including
 discounted cash flow models, quoted market values and third-party
 independent appraisals, as considered necessary. There were no
 impairment charges recognized in the years ended December&amp;#xA0;31,
 2018 and December&amp;#xA0;31, 2019.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Fair Value of Financial Instruments&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company applies fair value accounting for all financial assets
 and liabilities and nonfinancial assets and liabilities that are
 required to be recognized or disclosed at fair value in the
 consolidated financial statements. The Company defines fair value
 as the price that would be received from selling an asset or paid
 to transfer a liability in an orderly transaction between market
 participants at the measurement date. Where observable prices or
 inputs are not available valuation models are applied. These
 valuation techniques involve some level of management estimation
 and judgment, the degree of which is dependent on the price
 transparency for the instruments or market and the
 instruments&amp;#x2019; complexity.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s financial instruments consist of cash, accounts
 receivable, accounts payable, the term loan compound derivative
 liability and the Series B convertible preferred shares warrant
 liability. The term loan compound derivative liability and the
 Series B convertible preferred shares warrant liability are
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; at the end of
 every period and carried at fair value (Note 2). The recorded value
 of the Company&amp;#x2019;s accounts receivable and accounts payable
 approximates its current fair value due to the relatively
 short-term nature of these items.&lt;/p&gt;

 &lt;b&gt;Term Loan&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company accounts for the Loan and Security Agreement, dated as
 of December&amp;#xA0;20, 2019, with Silicon Valley Bank, and WestRiver
 Innovation Lending Fund VIII, LP, collectively as lenders, and
 Silicon Valley Bank, as administrative agent and collateral agent,
 as a liability measured at net proceeds less debt discount and is
 accreted to the face value of the term loan over its expected term
 using the effective interest method. The Company considers whether
 there are any embedded features in its debt instruments that
 require bifurcation and separate accounting as derivative financial
 instruments pursuant to Accounting Standards Codification, or ASC,
 Topic 815, &lt;i&gt;Derivatives and&lt;/i&gt; &lt;i&gt;Hedging&lt;/i&gt;.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Convertible Preferred Shares&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company records convertible preferred shares net of issuance
 costs on the dates of issuance, which represents the carrying
 value. In the event of a change of control of the Company, proceeds
 will be distributed in accordance with the liquidation preferences
 set forth in its Constitution unless the holders of convertible
 preferred shares have converted their convertible preferred shares
 into ordinary shares. Convertible preferred shares are classified
 outside of shareholders&amp;#x2019; deficit on the accompanying
 consolidated balance sheets as events triggering the liquidation
 preferences are not solely within the Company&amp;#x2019;s control. The
 Company has elected not to adjust the carrying values of the
 convertible preferred shares to the liquidation preferences of such
 shares because of the uncertainty of whether or when such an event
 would occur.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Series B Convertible Preferred Shares Warrant Liability&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company has issued freestanding warrants to purchase its Series
 B convertible preferred shares. Freestanding warrants for the
 Company&amp;#x2019;s convertible preferred shares that are classified
 outside of permanent equity are recorded at fair value, and are
 subject to &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt;
 at each balance sheet date until the earlier of the exercise of the
 warrants or the completion of a liquidation event. Upon exercise,
 the Series B convertible preferred shares warrant liability would
 be reclassified to additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital, with any change in
 fair value recognized as a component of other income (expense),
 net.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 9px"&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt"&gt;
 &lt;b&gt;Revenue Recognition&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 To date, the Company has derived revenue from providing research
 and development services on a time and materials basis to a
 related-party. The Company recognizes such revenues over time as
 services are delivered, and invoices the customer as the work is
 incurred in arrears.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Effective January&amp;#xA0;1, 2018, the Company adopted ASC Topic 606,
 &lt;i&gt;Revenue from Contracts with Customers&lt;/i&gt; (Topic 606) on a full
 retrospective basis. This standard applies to all contracts with
 customers, except for contracts that are within the scope of other
 standards, such as leases, insurance, collaboration arrangements
 and financial instruments. In accordance with Topic 606, the
 Company recognizes revenue when its customer obtains control of
 promised goods or services, in an amount that reflects the
 consideration which the Company expects to receive in exchange for
 those goods or services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 To determine revenue recognition for arrangements that the Company
 determines are within the scope of Topic 606, the Company performs
 the following five steps: (i)&amp;#xA0;identify the contract(s) with a
 customer; (ii)&amp;#xA0;identify the performance obligations in the
 contract; (iii)&amp;#xA0;determine the transaction price;
 (iv)&amp;#xA0;allocate the transaction price to the performance
 obligations in the contract; and (v)&amp;#xA0;recognize revenue when
 (or as) the Company satisfies a performance obligation.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 As part of the Company&amp;#x2019;s consideration as to whether the
 Company has entered into a contract with a customer, it considers
 whether it is probable that it will collect the consideration it is
 entitled to in exchange for the goods and services it transfers to
 the customer. At contract inception, the Company assesses the goods
 or services promised within each contract that falls under the
 scope of Topic 606, determines those that are performance
 obligations, and assesses whether each promised good or service is
 distinct. The Company then recognizes as revenue the amount of the
 transaction price that is allocated based on their standalone
 selling price to the respective performance obligation when (or as)
 the performance obligation is satisfied.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Cost of Services for Related-Party Revenue&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company incurs costs associated with related-party services
 including direct labor and associated employee benefits, laboratory
 supplies, and other expenses. These costs are recorded in cost of
 services for related-party revenue as a component of total
 operating expenses in the accompanying consolidated statements of
 operations and comprehensive loss.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Research and Development Costs&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 Research and development costs are expensed as incurred and consist
 primarily of salaries and benefits, share-based compensation
 expense, lab supplies and facility costs, as well as fees paid to
 nonemployees and entities that conduct certain research and
 development activities on behalf of the Company and expenses
 incurred in connection with license agreements (Note 9).
 Nonrefundable advance payments for goods or services to be received
 in the future for use in research and development activities are
 capitalized and recorded in prepaid expenses and other current
 assets, and then expensed as the related goods are delivered or the
 services are performed.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Clinical and Manufacturing Accruals&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company records accruals for estimated costs of research,
 preclinical studies and clinical trials, and manufacturing
 development, which are a significant component of research and
 development expenses. A substantial portion of the Company&amp;#x2019;s
 ongoing research and development activities are conducted by
 third-party service providers, including contract research
 organizations, or CROs, and contract manufacturing organizations,
 or CMOs. The Company&amp;#x2019;s contracts with CROs generally include
 pass-through fees such as regulatory expenses, investigator fees,
 travel costs and other miscellaneous costs, including shipping and
 printing fees. The financial terms of these contracts are subject
 to negotiations, which vary from contract to contract and may
 result in payment flows that do not match the periods over which
 materials or services are provided to the Company under such
 contracts. The Company accrues the costs incurred under agreements
 with these third parties based on estimates of actual work
 completed in accordance with the respective agreements. The Company
 determines the estimated costs through discussions with internal
 personnel and external service providers as to the progress or
 stage of completion of the services and the agreed-upon fees to be
 paid for such services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 6px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt"&gt;
 The Company makes significant judgments and estimates in
 determining the accrual balance at the end of each reporting
 period. As actual costs become known, the Company adjusts its
 accruals. Although the Company does not expect its estimates to be
 materially different from amounts actually incurred, the
 Company&amp;#x2019;s understanding of the status and timing of services
 performed relative to the actual status and timing of services
 performed may vary and could result in the Company reporting
 amounts that are too high or too low in any particular period. To
 assist in its estimates the Company relies upon the receipt of
 timely and accurate reporting from information provided as part of
 its clinical and &lt;font style="WHITE-SPACE: nowrap"&gt;non-clinical&lt;/font&gt; studies and other
 third-party vendors. Through December&amp;#xA0;31, 2019, there have
 been no material differences from the Company&amp;#x2019;s accrued
 estimated expenses to the actual clinical trial expenses. However,
 variations in the assumptions used to estimate accruals, including,
 but not limited to, the number of patients enrolled, the rate of
 patient enrollment, and the actual services performed, and related
 costs may vary from the Company&amp;#x2019;s estimates, resulting in
 adjustments to clinical trial expense in future periods. Changes in
 these estimates that result in material changes to the
 Company&amp;#x2019;s accruals could materially affect its financial
 position and results of operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Share-Based Compensation Expense&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company accounts for share-based compensation by measuring and
 recognizing compensation expense for all share-based payments made
 to employees, directors and &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees&lt;/font&gt; based on estimated
 grant-date fair values. The Company uses the straight-line method
 to allocate compensation expense to reporting periods over each
 optionee&amp;#x2019;s requisite service period, which is generally the
 vesting period, and estimates the fair value of share-based awards
 to employees and directors using the Black-Scholes option-pricing
 model. The Black-Scholes model requires the input of subjective
 assumptions, including expected volatility, expected dividend
 yield, expected term, risk-free rate of return and the estimated
 fair value of the underlying ordinary shares on the date of grant.
 The Company accounts for the effect of forfeitures as they
 occur.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Segment Reporting&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company manages its operations as a single operating segment
 for the purposes of assessing performance and making operating
 decisions. All of the Company&amp;#x2019;s assets are maintained in the
 United States and Ireland.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Foreign Currency Transactions&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The functional currency of the Company&amp;#x2019;s operation and each
 of its subsidiaries is U.S. dollars. All assets and liabilities
 denominated in a foreign currency are translated into U.S. dollars
 at the exchange rate prevailing on the balance sheet date. Expenses
 are translated at the average exchange rates prevailing during the
 applicable period. Foreign currency transaction gains and losses
 are included in the consolidated statement of operations and
 comprehensive loss and recorded in other income (expense), net, and
 was immaterial for the years ended December&amp;#xA0;31, 2018 and
 December&amp;#xA0;31, 2019, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Income Taxes&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company accounts for income taxes under the asset and liability
 method, which requires the recognition of deferred tax assets and
 liabilities for the expected future tax consequences of events that
 have been included in the consolidated financial statements. Under
 this method, deferred tax assets and liabilities are determined on
 the basis of the differences between the consolidated financial
 statement carrying amounts and tax bases of assets and liabilities
 using enacted tax rates in effect for the period in which the
 temporary differences are expected to reverse. The effect of a
 change in tax rates on deferred tax assets and liabilities is
 recognized in the consolidated statements of operations and
 comprehensive loss in the period that includes the enactment
 date.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company recognizes deferred tax assets to the extent that it
 believes these assets are more likely than not to be realized. In
 making such a determination, the Company considers all available
 positive and negative evidence, including future reversals of
 existing taxable temporary differences, projected future taxable
 income, &lt;font style="WHITE-SPACE: nowrap"&gt;tax-planning&lt;/font&gt;
 strategies and results of recent operations. If the Company
 determines that it would be able to realize its deferred tax assets
 in the future in excess of their net recorded amount, it would make
 an adjustment to the deferred tax asset valuation allowance, which
 would reduce the provision for income taxes.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company recognizes benefits of uncertain tax positions if it is
 more likely than not that such positions will be sustained upon
 examination based solely on their technical merits, as the largest
 amount of benefit that is more likely than not to be realized upon
 the ultimate settlement. The Company&amp;#x2019;s policy is to recognize
 interest and penalties related to the underpayment of income taxes
 as a component of income tax expense or benefit.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Net Loss Per Share Attributable to Ordinary Shareholders&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 Basic net loss per share is calculated by dividing the net loss
 attributable to ordinary shareholders by the weighted-average
 number of ordinary shares outstanding during the period, without
 consideration for ordinary share equivalents. Net loss attributable
 to ordinary shareholders is calculated by adjusting net loss of the
 Company for cumulative preferred share dividends. Diluted net loss
 per share is the same as basic net loss per share, since the
 effects of potentially dilutive securities are antidilutive given
 the net loss for each period presented.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company applies the &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method to compute basic and
 diluted net loss per share when it has issued shares that meet the
 definition of participating securities. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method determines net loss
 per share for each class of ordinary and participating securities
 according to dividends declared or accumulated and participation
 rights in undistributed earnings. The &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method requires net loss
 available to ordinary shareholders for the period to be allocated
 between ordinary and participating securities based upon their
 respective rights to share in the earnings as if all net loss for
 the period had been distributed. The Company&amp;#x2019;s convertible
 preferred shares participate in any dividends declared by the
 Company and are therefore considered to be participating
 securities. The participating securities are not required to
 participate in the losses of the Company, and therefore during
 periods of loss there is no allocation required under the
 &lt;font style="WHITE-SPACE: nowrap"&gt;two-class&lt;/font&gt; method.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;Unaudited Pro Forma Net Loss Per Share Attributable to Ordinary
 Shareholders&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 In contemplation of an initial public offering, or IPO, the Company
 has presented unaudited pro forma basic and diluted net loss per
 share attributable to ordinary shareholders for the year ended
 December&amp;#xA0;31, 2019. Unaudited pro forma basic net loss per
 share attributable to ordinary shareholders as of December&amp;#xA0;31,
 2019 is computed to give effect to adjustments to the denominator
 in the pro forma basic and diluted net loss per share calculation
 to reflect the conversion of all of the Company&amp;#x2019;s outstanding
 convertible preferred shares and cumulative dividends into
 11,253,839 ordinary shares, as if the conversion had occurred as of
 the beginning of the period or the original date of issuance, if
 later.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Unaudited pro forma diluted net loss attributable to ordinary
 shareholders is the same as unaudited pro forma basic net loss per
 share attributable to ordinary shareholders for the period as the
 impact of any potentially dilutive securities was anti-dilutive,
 which has been computed to give effect to the adjustment noted
 above. The pro forma net loss per share attributable to ordinary
 shareholders does not include proceeds to be received from nor does
 it include shares expected to be sold in the assumed IPO.&lt;/p&gt;

 &lt;b&gt;Recent Accounting Pronouncements&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 From time to time, new accounting pronouncements are issued by the
 Financial Accounting Standards Board, or FASB, or other standard
 setting bodies and adopted by the Company as of the specified
 effective date. Unless otherwise discussed, the impact of recently
 issued standards that are not yet effective will not have a
 material impact on the Company&amp;#x2019;s financial position or
 results of operations upon adoption.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In February 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; (Topic 842),
 &lt;i&gt;Leases&lt;/i&gt; (ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02).&lt;/font&gt; ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; requires an entity to
 recognize assets and liabilities arising from a lease for both
 financing and operating leases. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; will also require new
 qualitative and quantitative disclosures to help investors and
 other financial statement users better understand the amount,
 timing, and uncertainty of cash flows arising from leases. In
 November 2019, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2019-10,&lt;/font&gt; which extends the
 effective date of ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; for &lt;font style="WHITE-SPACE: nowrap"&gt;non-public&lt;/font&gt; business entities,
 including smaller reporting companies, to fiscal years beginning
 after December&amp;#xA0;15, 2020. The new standard is effective for the
 Company beginning January&amp;#xA0;1, 2021. Early adoption is
 permitted. The Company is currently evaluating the effects of the
 adoption of this guidance on its consolidated financial statements
 and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In June 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-13,&lt;/font&gt; &lt;i&gt;Financial
 Instruments-Credit Losses&lt;/i&gt; (Topic 326), which requires entities
 to measure all expected credit losses for financial assets held at
 the reporting date based on historical experience, current
 conditions, and reasonable and supportable forecasts. This replaces
 the existing incurred loss model and is applicable to the
 measurement of credit losses on financial assets measured at
 amortized cost. In February 2020, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2020-02&lt;/font&gt; and delayed the
 effective date of Topic 326 until fiscal year beginning after
 December&amp;#xA0;15, 2022. The new standard is effective for the
 Company beginning January&amp;#xA0;1, 2023. Early adoption is
 permitted. The Company is currently evaluating the effects of the
 adoption of this guidance on its consolidated financial statements
 and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In December 2019, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2019-12,&lt;/font&gt; &lt;i&gt;Income Taxes&lt;/i&gt;
 (Topic 740): Simplifying the Accounting for Income Taxes, which is
 intended to simplify various aspects related to accounting for
 income taxes. The pronouncement is effective for fiscal years, and
 for interim periods within those fiscal years, beginning after
 December&amp;#xA0;15, 2021. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2019-12&lt;/font&gt; is effective for the Company
 beginning January&amp;#xA0;1, 2022. Early adoption is permitted. The
 Company is currently in the process of evaluating the effects of
 the adoption of this guidance on the Company&amp;#x2019;s financial
 statements and does not expect it to have a material impact on its
 consolidated financial statements.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 In November 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-18,&lt;/font&gt; &lt;i&gt;Statement of Cash
 Flows&lt;/i&gt; (Topic 230): Restricted Cash, which requires that
 restricted cash and cash equivalents be included as components of
 total cash and cash equivalents as presented on the statement of
 cash flows. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-18&lt;/font&gt;
 was effective for fiscal years beginning after December&amp;#xA0;15,
 2018, and a retrospective transition method is required. The
 Company adopted this guidance on January&amp;#xA0;1, 2019. The adoption
 of this guidance did not have a material impact on the
 Company&amp;#x2019;s consolidated financial statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In July 2017, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2017-11,&lt;/font&gt; &lt;i&gt;Earnings Per
 Share&lt;/i&gt; (Topic 260); &lt;i&gt;Distinguishing Liabilities from
 Equity&lt;/i&gt; (Topic 480): Accounting for Certain Financial
 Instruments with Down Round Features. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2017-11&lt;/font&gt; provides guidance
 that eliminates the requirement to consider &amp;#x201C;down
 round&amp;#x201D; features when determining whether certain financial
 instruments or embedded features are indexed to an entity&amp;#x2019;s
 stock and need to be classified as liabilities. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2017-11&lt;/font&gt; provides for entities to
 recognize the effect of a down round feature only when it is
 triggered and then as a dividend and a reduction to income
 available to common stockholders in basic earnings per share. The
 Company adopted this guidance on January&amp;#xA0;1, 2019. The adoption
 of this guidance did not have a material impact on the
 Company&amp;#x2019;s consolidated financial statements.&lt;/p&gt;

 &lt;i&gt;Exclusive (Equity) Agreement with The Board of Trustees of the
 Leland Stanford Junior University&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 In March 2015, the Company entered into a license agreement, or the
 Stanford Agreement, with the Board of Trustees of the Leland
 Stanford Junior University, or Stanford, under which the Company
 obtained a worldwide, royalty-bearing, sublicensable license under
 certain patents relating to the Company&amp;#x2019;s current product
 candidates, to develop, manufacture and commercialize products for
 use in certain licensed fields, the scope of which would include
 the application of the licensed intellectual property in oncology.
 The license granted to the Company in the Stanford Agreement
 includes an exclusive grant, subject to certain &lt;font style="WHITE-SPACE: nowrap"&gt;pre-existing&lt;/font&gt; &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive&lt;/font&gt; or exclusive rights that
 Stanford retained for grant to third parties with respect to
 certain categories of the licensed patents in certain fields of use
 and retained rights by Stanford and all other nonprofit
 institutions to use and practice the licensed patents and
 technology for internal research and other nonprofit purposes. The
 license granted to the Company in the Stanford Agreement also
 includes &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive&lt;/font&gt;
 grants to certain Stanford patents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In consideration for the rights granted to the Company under the
 Stanford Agreement, the Company paid Stanford a nonrefundable
 license royalty and reimbursed Stanford for past patent expenses,
 together totaling less than $0.1&amp;#xA0;million, and granted Stanford
 a specified number of ordinary shares of the Company. In addition,
 the Company is obligated to pay Stanford ongoing patent expenses
 and an annual license maintenance fee, which are nominal and will
 be creditable against any royalties payable to Stanford in the
 applicable year. The Company is required to make milestone payments
 up to an aggregate of $5.0&amp;#xA0;million in respect of a specified
 number of licensed products that successfully satisfy certain
 clinical and regulatory milestones. No milestone payments have been
 made through December&amp;#xA0;31, 2019. The Company also agreed to pay
 Stanford tiered royalties on a specified percentage of net sales
 made by the Company, its affiliates and its sublicensees of
 licensed products at rates ranging within low single-digit
 percentages, subject to certain reductions and offsets. The
 license, on a licensed &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-licensed&lt;/font&gt;&lt;/font&gt; product and
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;country-by-country&lt;/font&gt;&lt;/font&gt; basis, shall
 become royalty-free and fully &lt;font style="WHITE-SPACE: nowrap"&gt;paid-up&lt;/font&gt; upon the later of the date on
 which the last valid claim included in the exclusively or
 &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusively&lt;/font&gt; licensed
 patents expires and ten years after the first commercial sale of
 the licensed product in such country.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company may terminate the Stanford Agreement, on a licensed
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-licensed&lt;/font&gt;&lt;/font&gt; product
 basis, at any time for any reason by providing at least 60
 days&amp;#x2019; written notice to Stanford. Stanford may terminate the
 Stanford Agreement, if the Company is in breach of any provision of
 the Stanford Agreement and fail to remedy such breach within 60
 days after written notice of such breach by Stanford. In addition,
 Stanford has the right to terminate the Stanford Agreement, on a
 licensed &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-licensed&lt;/font&gt;&lt;/font&gt; product
 basis, if the Company is not diligently developing and
 commercializing such licensed product under certain conditions or
 if the Company fails to achieve specified development milestones
 for such licensed product by certain dates, subject to the
 Company&amp;#x2019;s extension rights.&lt;/p&gt;

 &lt;i&gt;Commercial License Agreement with Selexis SA&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 In June 2016, the Company entered into a license agreement with
 Selexis SA, or Selexis, under which the Company obtained a
 worldwide, royalty-bearing, sublicensable license under certain
 patents, &lt;font style="WHITE-SPACE: nowrap"&gt;know-how&lt;/font&gt; and
 other intellectual property, to use Selexis generated cell lines to
 manufacture ALX148 and to make, use and sell licensed products
 containing such compound in all fields of use. The rights granted
 under this agreement include the rights to grant sublicenses to
 contractors or other collaboration partners, in each case to
 develop production processes or manufacture licensed products
 containing ALX148.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In consideration for the rights granted to the Company under the
 agreement, the Company paid Selexis a nominal &lt;font style="WHITE-SPACE: nowrap"&gt;one-time&lt;/font&gt; fee and will pay Selexis an
 annual maintenance fee. The Company also agreed to pay Selexis
 milestone payments up to an aggregate of 1.2&amp;#xA0;million Swiss
 Francs in respect of all licensed products developed and/or
 commercialized under the grant that successfully satisfies certain
 milestone events. The Company also agreed to pay Selexis a flat
 royalty of a very low single-digit percentage on net sales made by
 the Company, its affiliates and sublicensees of products. This
 royalty obligation, on a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-product&lt;/font&gt;&lt;/font&gt; and
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;country-by-country&lt;/font&gt;&lt;/font&gt; basis, shall
 terminate and become fully &lt;font style="WHITE-SPACE: nowrap"&gt;paid-up&lt;/font&gt; upon the passing of ten years
 after the first commercial sale of the product in such country, or
 the Company&amp;#x2019;s exercise of the royalty buyout option
 exercisable at any time prior to the first commercial sale of a
 licensed product.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company may terminate the license agreement at any time for any
 reason with at least 60 days&amp;#x2019; written notice to Selexis.
 Either party may terminate the license agreement if the other party
 enters into a bankruptcy event or in the event of a material breach
 of the agreement (that cannot be cured or remains uncured for 60
 days after the date that the defaulting party is provided with
 written notice of such breach). The Company&amp;#x2019;s obligations to
 pay royalties that are accrued or accruable will survive any
 termination of the agreement, and in certain circumstances the
 licenses granted under the agreement will terminate unless they
 have become fully paid up as described in the previous
 paragraph.&lt;/p&gt;

 &lt;i&gt;Commercial Antibody Agreement with Crystal Bioscience, Inc. (Now
 a Subsidiary of Ligand Pharmaceuticals Incorporated)&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 In March 2017, the Company entered into an agreement with Crystal
 Bioscience, Inc. (now a subsidiary of Ligand Pharmaceuticals
 Incorporated), or Crystal, under which the Company obtained an
 assignment of certain patents, covering certain SIRP&lt;font style="FONT-FAMILY: Times New Roman"&gt;&lt;font style="FONT-FAMILY: SYMBOL"&gt;a&lt;/font&gt;&lt;/font&gt; antibodies. Under this
 agreement, the Company also received a worldwide, royalty-bearing
 &lt;font style="WHITE-SPACE: nowrap"&gt;non-exclusive&lt;/font&gt; license,
 with the right to grant sublicenses through multiple tiers of
 sublicenses, under certain of Crystal&amp;#x2019;s background patents
 and &lt;font style="WHITE-SPACE: nowrap"&gt;know-how&lt;/font&gt; necessary to
 commercialize the rights under the assigned patents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In consideration for the rights granted to the Company under the
 agreement, it agreed to pay Crystal milestone payments up to
 $11.1&amp;#xA0;million in respect of all licensed products developed
 under the assigned patents, that successfully satisfy certain
 clinical and regulatory milestones, each milestone being paid only
 once for all products. The Company also agreed to pay Crystal
 tiered royalties on net sales made by the Company, its affiliates
 and sublicensees of products at rates ranging within low
 single-digit percentages, subject to certain potential reductions.
 This royalty obligation, on a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;product-by-product&lt;/font&gt;&lt;/font&gt; and
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;country-by-country&lt;/font&gt;&lt;/font&gt; basis, shall
 terminate and become fully &lt;font style="WHITE-SPACE: nowrap"&gt;paid-up&lt;/font&gt; upon the later of the date on
 which the last valid claim included in the licensed patents expires
 and ten years after the first commercial sale of the product in
 such country.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company agreed to use commercially reasonable efforts to
 develop and commercialize licensed products, including meeting
 defined development milestones by certain specified dates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company may terminate the agreement at any time for any reason
 with at least 60 days&amp;#x2019; written notice to Crystal. Either
 party may terminate the agreement if the other party enters into a
 bankruptcy event or in the event of material breach of the
 agreement (that remains uncured for 60 days after the date that it
 is provided with written notice of such breach). The
 Company&amp;#x2019;s obligations to pay royalties and milestone payments
 which accrued &lt;font style="WHITE-SPACE: nowrap"&gt;pre-termination&lt;/font&gt; or accrue
 post-termination will survive any termination.&lt;/p&gt;

 In the normal course of business, the Company enters into contracts
 and agreements that contain a variety of representations and
 warranties and provide for general indemnifications. The
 Company&amp;#x2019;s exposure under these agreements is unknown because
 it involves claims that may be made against the Company in the
 future but have not yet been made. To date, the Company has not
 paid any claims or been required to defend any action related to
 its indemnification obligations. However, the Company may record
 charges in the future as a result of these indemnification
 obligations. The Company also has indemnification obligations to
 its officers and directors for specified events or occurrences,
 subject to some limits, while they are serving at the
 Company&amp;#x2019;s request in such capacities. There have been no
 claims to date and the Company has director and officer insurance
 that may enable the Company to recover a portion of any amounts
 paid for future potential claims. The Company believes the fair
 value of these indemnification agreements is minimal. Accordingly,
 the Company has not recorded any liabilities for these agreements
 as of December&amp;#xA0;31, 2018 and December&amp;#xA0;31, 2019.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 From time to time, the Company may be a party to various claims in
 the normal course of business. Legal fees and other costs
 associated with such actions will be expensed as incurred. The
 Company will assess, in conjunction with its legal counsel, the
 need to record a liability for litigation and contingencies.
 Reserve estimates will be recorded when and if it is determined
 that a loss related matter is both probable and reasonably
 estimable. For the years ended December&amp;#xA0;31, 2018 and
 December&amp;#xA0;31, 2019, the Company had no pending or threatened
 litigation.&lt;/p&gt;

 The Company and its wholly-owned subsidiaries Alexo Therapeutics
 International and Sirpant Therapeutics, as borrowers, entered into
 a Loan and Security Agreement, or the Loan Agreement, dated as of
 December&amp;#xA0;20, 2019, with Silicon Valley Bank, or SVB, and
 WestRiver Innovation Lending Fund VIII, LP, or WestRiver,
 collectively as lenders, and SVB, as administrative agent and
 collateral agent. The Loan Agreement provides for term loans in an
 aggregate principal amount of up to $10.0&amp;#xA0;million funded in
 two tranches, subject to the satisfaction of a certain milestone.
 The first tranche, in the amount of $6.0&amp;#xA0;million, was funded
 on the closing date of the Loan Agreement in December 2019. A
 second tranche of $4.0&amp;#xA0;million was available on or before
 March&amp;#xA0;31, 2020, upon the Company&amp;#x2019;s achievement of an
 equity financing resulting in net cash proceeds in an amount of at
 least $30.0&amp;#xA0;million to the Company. The Company elected not to
 draw down on the second tranche, which is no longer available.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The loans under the Loan Agreement bear interest at a floating per
 annum interest rate equal to the greater of 7.0% or 2.0% plus the
 prime rate as reported in The Wall Street Journal. The Wall Street
 Journal prime rate was 4.75% as of December&amp;#xA0;31, 2019.
 Therefore, the rate applicable to the Company as of
 December&amp;#xA0;31, 2019 was 7.0%.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company is required to make interest-only payments for the
 first 12 months after the closing of the Loan Agreement, followed
 by consecutive equal monthly payments of principal and interest
 commencing on January&amp;#xA0;1, 2021 and continuing through the
 maturity date of September&amp;#xA0;1, 2022. The Loan Agreement also
 provides for a final payment equal to 6.0% multiplied by the
 aggregate principal amount of the term loans funded, which is due
 on the maturity date, upon the acceleration of the term loans, or
 upon prepayment of the term loans. If the Company elects to prepay
 the term loans, there is also a prepayment fee of between 1.0% and
 3.0% of the principal amount being prepaid depending on the timing
 and circumstances of prepayment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In conjunction with the Loan Agreement, the Company has issued
 warrants to purchase 61,292 Series B convertible preferred shares
 to SVB and WestRiver with an exercise price of $9.4972 per share.
 The estimated fair value of the warrants at the date of issuance
 was approximately $0.4&amp;#xA0;million. The fair value of the Series B
 convertible preferred shares warrant liability was determined using
 the Black-Scholes option-pricing model. As of December&amp;#xA0;20,
 2019, the various assumptions used in the option-pricing model were
 time to liquidity of 2.0 to 10.0 years, volatility of 85.5%,
 risk-free rate of 1.7% and equity value of $345.0&amp;#xA0;million. It
 was recorded at its fair value at inception and is being
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; at each
 financial reporting period with any changes in fair value being
 recognized as a component of other income (expense), net in the
 accompanying consolidated statement of operations and comprehensive
 loss. As of December&amp;#xA0;31, 2019, the fair value of the Series B
 convertible preferred shares warrant liability was approximately
 $0.4&amp;#xA0;million and was recorded in other long-term liabilities
 on the consolidated balance sheet.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The loans under the Loan Agreement are secured by substantially all
 of the Company&amp;#x2019;s assets, except the Company&amp;#x2019;s
 intellectual property, which is the subject of a negative
 pledge.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company determined that certain loan features were embedded
 derivatives requiring bifurcation and separate accounting. Those
 embedded derivatives were bundled together as a single, compound
 embedded derivative and then bifurcated and accounted for
 separately from the host contract. The Company recorded a term loan
 compound derivative liability of approximately $51,000 which will
 be &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;marked-to-market&lt;/font&gt;&lt;/font&gt; in future
 periods. The Company calculated the fair value of the compound
 derivative by computing the difference between the fair value of
 the term loan with the compound derivative using the &amp;#x201C;with
 and without&amp;#x201D; method under the income approach, and the fair
 value of the term loan without the compound derivative. The Company
 calculated the fair values using a probability-weighted discounted
 cash flow analysis. The key valuation assumptions used consist of
 the discount rate and the probability of the occurrence of a change
 in control event. The term loan compound derivative liability is
 being &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; at each
 financial reporting period with any changes in fair value being
 recognized as a component of other income (expense), net in the
 consolidated statement of operations and comprehensive loss. As of
 December&amp;#xA0;31, 2019, the fair value of the compound derivative
 liability was approximately $51,000 and was recorded in other
 long-term liabilities on the consolidated balance sheet.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The fair value of Series B convertible preferred shares warrant
 liability at issuance, fair value of embedded derivatives which
 were bifurcated and other debt issuance costs have been treated as
 debt discounts on the Company&amp;#x2019;s consolidated balance sheet
 and together with the final payment are being amortized to interest
 expense throughout the life of the term loan using the effective
 interest rate method.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 As of December&amp;#xA0;31, 2019, there were unamortized issuance costs
 and debt discounts of $0.6&amp;#xA0;million which were recorded as a
 direct deduction from the term loan on the consolidated balance
 sheet. Interest expense for the term loan was immaterial for the
 year ended December&amp;#xA0;31, 2019. For future payments of principal
 and interest as of December&amp;#xA0;31, 2019 is as follows.&lt;/p&gt;

 restricted cash and cash equivalents be included as components of
 total cash and cash equivalents as presented on the statement of
 cash flows. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-18&lt;/font&gt;
 was effective for fiscal years beginning after December&amp;#xA0;15,
 2018, and a retrospective transition method is required. The
 Company adopted this guidance on January&amp;#xA0;1, 2019. The adoption
 of this guidance did not have a material impact on the
 Company&amp;#x2019;s consolidated financial statements.&lt;/p&gt;

 Share&lt;/i&gt; (Topic 260); &lt;i&gt;Distinguishing Liabilities from
 Equity&lt;/i&gt; (Topic 480): Accounting for Certain Financial
 Instruments with Down Round Features. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2017-11&lt;/font&gt; provides guidance
 that eliminates the requirement to consider &amp;#x201C;down
 round&amp;#x201D; features when determining whether certain financial
 instruments or embedded features are indexed to an entity&amp;#x2019;s
 stock and need to be classified as liabilities. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2017-11&lt;/font&gt; provides for entities to
 recognize the effect of a down round feature only when it is
 triggered and then as a dividend and a reduction to income
 available to common stockholders in basic earnings per share. The
 Company adopted this guidance on January&amp;#xA0;1, 2019. The adoption
 of this guidance did not have a material impact on the
 Company&amp;#x2019;s consolidated financial statements.&lt;/p&gt;

 &lt;b&gt;Revenue Recognition&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 To date, the Company has derived revenue from providing research
 and development services on a time and materials basis to a
 related-party. The Company recognizes such revenues over time as
 services are delivered, and invoices the customer as the work is
 incurred in arrears.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Effective January&amp;#xA0;1, 2018, the Company adopted ASC Topic 606,
 &lt;i&gt;Revenue from Contracts with Customers&lt;/i&gt; (Topic 606) on a full
 retrospective basis. This standard applies to all contracts with
 customers, except for contracts that are within the scope of other
 standards, such as leases, insurance, collaboration arrangements
 and financial instruments. In accordance with Topic 606, the
 Company recognizes revenue when its customer obtains control of
 promised goods or services, in an amount that reflects the
 consideration which the Company expects to receive in exchange for
 those goods or services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 To determine revenue recognition for arrangements that the Company
 determines are within the scope of Topic 606, the Company performs
 the following five steps: (i)&amp;#xA0;identify the contract(s) with a
 customer; (ii)&amp;#xA0;identify the performance obligations in the
 contract; (iii)&amp;#xA0;determine the transaction price;
 (iv)&amp;#xA0;allocate the transaction price to the performance
 obligations in the contract; and (v)&amp;#xA0;recognize revenue when
 (or as) the Company satisfies a performance obligation.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 As part of the Company&amp;#x2019;s consideration as to whether the
 Company has entered into a contract with a customer, it considers
 whether it is probable that it will collect the consideration it is
 entitled to in exchange for the goods and services it transfers to
 the customer. At contract inception, the Company assesses the goods
 or services promised within each contract that falls under the
 scope of Topic 606, determines those that are performance
 obligations, and assesses whether each promised good or service is
 distinct. The Company then recognizes as revenue the amount of the
 transaction price that is allocated based on their standalone
 selling price to the respective performance obligation when (or as)
 the performance obligation is satisfied.&lt;/p&gt;

 The Company manages its operations as a single operating segment

 United States and Ireland.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company accounts for share-based compensation by measuring and
 recognizing compensation expense for all share-based payments made
 to employees, directors and &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees&lt;/font&gt; based on estimated
 grant-date fair values. The Company uses the straight-line method
 to allocate compensation expense to reporting periods over each
 optionee&amp;#x2019;s requisite service period, which is generally the
 vesting period, and estimates the fair value of share-based awards
 to employees and directors using the Black-Scholes option-pricing
 model. The Black-Scholes model requires the input of subjective
 assumptions, including expected volatility, expected dividend
 yield, expected term, risk-free rate of return and the estimated
 fair value of the underlying ordinary shares on the date of grant.
 The Company accounts for the effect of forfeitures as they
 occur.&lt;/p&gt;

 The Company records convertible preferred shares net of issuance
 costs on the dates of issuance, which represents the carrying
 value. In the event of a change of control of the Company, proceeds
 will be distributed in accordance with the liquidation preferences
 set forth in its Constitution unless the holders of convertible
 preferred shares have converted their convertible preferred shares
 into ordinary shares. Convertible preferred shares are classified
 outside of shareholders&amp;#x2019; deficit on the accompanying
 consolidated balance sheets as events triggering the liquidation
 preferences are not solely within the Company&amp;#x2019;s control. The
 Company has elected not to adjust the carrying values of the
 convertible preferred shares to the liquidation preferences of such
 shares because of the uncertainty of whether or when such an event
 would occur.&lt;/p&gt;

 The preparation of consolidated financial statements in conformity
 with U.S. GAAP requires management to make estimates and
 assumptions that affect the reported amounts of assets and
 liabilities and disclosure of contingent assets and liabilities at
 the date of the consolidated financial statements and the reported
 amounts of revenues and expenses during the reporting periods. On
 an ongoing basis, management evaluates its estimates, including
 those related to the estimated useful lives of long-lived assets,
 clinical trial accruals, fair value of assets and liabilities,
 Series B convertible preferred shares warrant liability, term loan
 compound derivative liability, term loan, valuation of ordinary
 shares, income taxes and share-based compensation. Management bases
 its estimates on historical experience and on various other
 market-specific and relevant assumptions that management believes
 to be reasonable under the circumstances. Actual results could
 differ from those estimates.&lt;/p&gt;

 The Company reviews property and equipment for impairment whenever
 events or changes in circumstances indicate that the carrying
 amount of an asset may not be recoverable. Recoverability is
 measured by comparison of the carrying amount to the future
 undiscounted net cash flows which the asset or asset group are
 expected to generate. If such assets are considered to be impaired,
 the impairment to be recognized is measured as the amount by which
 the carrying amount of the assets exceeds its fair value. Fair
 value is determined using various valuation techniques including
 discounted cash flow models, quoted market values and third-party
 independent appraisals, as considered necessary. There were no
 impairment charges recognized in the years ended December&amp;#xA0;31,
 2018 and December&amp;#xA0;31, 2019.&lt;/p&gt;

 The Company accounts for income taxes under the asset and liability
 method, which requires the recognition of deferred tax assets and
 liabilities for the expected future tax consequences of events that
 have been included in the consolidated financial statements. Under
 this method, deferred tax assets and liabilities are determined on
 the basis of the differences between the consolidated financial
 statement carrying amounts and tax bases of assets and liabilities
 using enacted tax rates in effect for the period in which the
 temporary differences are expected to reverse. The effect of a
 change in tax rates on deferred tax assets and liabilities is
 recognized in the consolidated statements of operations and
 comprehensive loss in the period that includes the enactment
 date.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company recognizes deferred tax assets to the extent that it
 believes these assets are more likely than not to be realized. In
 making such a determination, the Company considers all available
 positive and negative evidence, including future reversals of
 existing taxable temporary differences, projected future taxable
 income, &lt;font style="WHITE-SPACE: nowrap"&gt;tax-planning&lt;/font&gt;
 strategies and results of recent operations. If the Company
 determines that it would be able to realize its deferred tax assets
 in the future in excess of their net recorded amount, it would make
 an adjustment to the deferred tax asset valuation allowance, which
 would reduce the provision for income taxes.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company recognizes benefits of uncertain tax positions if it is
 more likely than not that such positions will be sustained upon
 examination based solely on their technical merits, as the largest
 amount of benefit that is more likely than not to be realized upon
 the ultimate settlement. The Company&amp;#x2019;s policy is to recognize
 interest and penalties related to the underpayment of income taxes
 as a component of income tax expense or benefit.&lt;/p&gt;

 &lt;/table&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 During 2015, the Company adopted an equity compensation plan, the
 2015 Share Award Scheme, or the Plan, for eligible employees,
 officers, directors, advisors, and consultants. The Plan provides
 for the grant of incentive and &lt;font style="WHITE-SPACE: nowrap"&gt;non-statutory&lt;/font&gt; share options. The Plan
 permits the Company to grant up to 2,143,117 ordinary share awards,
 including incentive share options, &lt;font style="WHITE-SPACE: nowrap"&gt;non-statutory&lt;/font&gt; share options,
 conditional share awards and restricted share awards.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The terms of the share option agreements, including vesting
 requirements, are determined by the Board of Directors, subject to
 the provisions of the Plan. The term of the options generally
 expire, upon the earliest of (i)&amp;#xA0;termination of continuous
 service for cause (ii)&amp;#xA0;three months after the termination of
 continuous service for reasons other than cause, death or
 disability (iii)&amp;#xA0;twelve months after the termination of
 continuous service due to disability (iv)&amp;#xA0;eighteen months
 after the employee&amp;#x2019;s death if the employee died during the
 period of continuous service (v)&amp;#xA0;expiration date in the grant
 notice or (vi)&amp;#xA0;the day before the tenth anniversary of the
 date of grant. The exercise price of the incentive share options
 must equal at least the fair market value of the share on the date
 of grant.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 All awards that are canceled, forfeited or expired are returned to
 the Plan and are available for grant in conjunction with the
 issuance of new awards. Share options granted are exercisable over
 a maximum term of 10 years from the date of grant and generally
 vest over an agreed service period, usually four years.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Certain share options granted under the Plan provide option holders
 the right to elect to exercise unvested options in exchange for
 ordinary shares. Such unvested ordinary shares are subject to a
 repurchase right held by the Company at the original issuance price
 in the event the optionee&amp;#x2019;s service to the Company is
 terminated either voluntarily or involuntarily. The right lapses as
 the underlying repurchase right expires. These repurchase terms are
 considered to be a forfeiture provision. The cash received from
 employees for exercise of unvested options is treated as a
 refundable deposit and is classified as a liability on the
 consolidated balance sheets. At December&amp;#xA0;31, 2018 and
 December&amp;#xA0;31, 2019, there were 116,048 and 34,024 unvested
 early exercised options and the liability related to these unvested
 options was $0.1&amp;#xA0;million and approximately $27,000,
 respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 9px"&gt;

 As of December&amp;#xA0;31, 2019, there was unrecognized share-based
 compensation expense of $0.6&amp;#xA0;million, related to unvested
 share options which the Company expects to recognize over a
 weighted-average period of 2.7 years.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The aggregate intrinsic values of options outstanding and
 exercisable were calculated as the difference between the exercise
 price of the options and the estimated fair value of the
 Company&amp;#x2019;s ordinary shares as determined by the Board of
 Directors as of December&amp;#xA0;31, 2018 and December&amp;#xA0;31, 2019.
 The total intrinsic value of options exercised during the years
 ended December&amp;#xA0;31, 2018 and 2019 were immaterial.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Compensation cost for share options granted is based on the
 grant-date fair value estimated and is recognized over the vesting
 period of the applicable option on a straight-line basis. The
 weighted-average grant-date fair value per share for share options
 granted during the years ended December&amp;#xA0;31, 2018 and
 December&amp;#xA0;31, 2019 was $1.14 and $1.27, respectively. The total
 fair value of options that vested during the years ended
 December&amp;#xA0;31, 2018 and December&amp;#xA0;31, 2019 was approximately
 $0.1&amp;#xA0;million and $0.3&amp;#xA0;million, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;

 The Company&amp;#x2019;s computation of share-based compensation expense
 for the years ended December&amp;#xA0;31, 2018 and December&amp;#xA0;31,
 2019 is based on the fair value of ordinary shares of $1.85 and
 $1.91, respectively, and is adjusted for actual forfeitures as they
 occur. The fair value of each option grant during the years ended
 December&amp;#xA0;31, 2018 and December&amp;#xA0;31, 2019 was estimated on
 the date of grant using the Black-Scholes option-pricing model with
 the following:&lt;/p&gt;

 &lt;i&gt;Expected Term.&lt;/i&gt; The expected term of the options represents
 the average period the share options are expected to remain
 outstanding. As the Company does not have sufficient historical
 information to develop reasonable expectations about future
 exercise patterns and post-vesting employment termination behavior,
 the expected term of options granted is derived from the average
 midpoint between the weighted average vesting and the contractual
 term, also known as the simplified method.&lt;/p&gt;

 &lt;i&gt;Risk-Free Interest Rate.&lt;/i&gt; The risk-free interest rate is
 based on the yield of U.S. Treasury notes as of the grant date with
 terms commensurate with the expected term of the option.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Dividend Yield.&lt;/i&gt; The expected dividends assumption is based
 on the Company&amp;#x2019;s expectation of not paying dividends in the
 foreseeablefuture.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Volatility.&lt;/i&gt; Since the Company is private and does not have
 any trading history for its ordinary shares, the expected
 volatility is based on the historical volatilities of the common
 shares of comparable publicly traded companies. The Company
 selected companies with comparable characteristics, including
 enterprise value, risk profiles, position within the industry, and
 with historical share price information sufficient to meet the
 expected life of the Company&amp;#x2019;s share-based awards.&lt;/p&gt;

 &lt;i&gt;Estimated Fair Value&lt;/i&gt;. The estimated fair value of the shares
 of common stock underlying stock options was determined by the
 Company&amp;#x2019;s board of directors. Because there was no public
 market for the Company&amp;#x2019;s common stock, the board of directors
 determined fair value of the common stock at the time of grant of
 the options by considering a number of objective and subjective
 factors including important developments in the Company&amp;#x2019;s
 operations, valuations performed by an independent third party,
 sales of convertible preferred stock, actual operating results and
 financial performance, the conditions in the biotechnology industry
 and the economy in general, the stock price performance and
 volatility of comparable public companies, and the lack of
 liquidity of the Company&amp;#x2019;s common stock, among other
 factors.&lt;/p&gt;

 On April&amp;#xA0;1, 2020, the Company completed an internal
 reorganization transaction pursuant to which ALX Oncology Limited
 became a wholly-owned subsidiary ALX Oncology Holdings Inc., a
 newly formed Delaware corporation. As part of the transaction, all
 of the equity, option and warrant holders of ALX Oncology Limited
 became equity, option and warrant holders of ALX Oncology Holdings
 Inc., holding the same number of corresponding shares, options
 and/or warrants in ALX Oncology Holdings Inc., as they did in the
 Company immediately prior to the reorganization.&lt;/p&gt;

 On July&amp;#xA0;8, 2020, the Company&amp;#x2019;s board of directors
 approved an amendment to ALX Oncology Holdings Inc.&amp;#x2019;s
 certificate of incorporation to effect a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;1-for-6.5806&lt;/font&gt;&lt;/font&gt; reverse split of
 its ordinary shares and convertible preferred shares. The par
 values of the ordinary and convertible preferred shares were not
 adjusted as a result of the reverse stock split. All authorized,
 issued and outstanding ordinary shares and convertible preferred
 shares and related per share amounts contained in the consolidated
 financial statements have been retroactively adjusted to reflect
 this reverse stock split for all periods presented. The reverse
 stock split was effected on July&amp;#xA0;9, 2020.&lt;/p&gt;

 Innovation Lending Fund VIII, LP, collectively as lenders, and

 as a liability measured at net proceeds less debt discount and is
 accreted to the face value of the term loan over its expected term
 using the effective interest method. The Company considers whether
 there are any embedded features in its debt instruments that
 require bifurcation and separate accounting as derivative financial

 The Company applies fair value accounting for all financial assets
 and liabilities and nonfinancial assets and liabilities that are
 required to be recognized or disclosed at fair value in the
 consolidated financial statements. The Company defines fair value
 as the price that would be received from selling an asset or paid
 to transfer a liability in an orderly transaction between market
 participants at the measurement date. Where observable prices or
 inputs are not available valuation models are applied. These
 valuation techniques involve some level of management estimation
 and judgment, the degree of which is dependent on the price
 transparency for the instruments or market and the
 instruments&amp;#x2019; complexity.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s financial instruments consist of cash, accounts
 receivable, accounts payable, the term loan compound derivative
 liability and the Series B convertible preferred shares warrant
 liability. The term loan compound derivative liability and the
 Series B convertible preferred shares warrant liability are
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; at the end of
 every period and carried at fair value (Note 2). The recorded value
 of the Company&amp;#x2019;s accounts receivable and accounts payable
 approximates its current fair value due to the relatively

 basic net loss per share is the same as diluted net loss per share
 for all periods as the inclusion of all potential ordinary shares

 calculations as of December&amp;#xA0;31, 2018 and December&amp;#xA0;31,
 2019 because they would be anti-dilutive were as follows:&lt;/p&gt;

 The fair value of the Company&amp;#x2019;s financial assets and
 liabilities are determined in accordance with the fair value
 hierarchy established in ASC Topic 820, &lt;i&gt;Fair Value Measurements
 and Disclosures&lt;/i&gt;. ASC Topic 820 defines fair value as the
 exchange price that would be received for an asset or paid to
 transfer a liability (an exit price) in the principal or most
 advantageous market for the asset or liability in an orderly
 transaction between market participants on the measurement date.
 The fair value hierarchy of ASC Topic 820 requires an entity to
 maximize the use of observable inputs when measuring fair value and
 classifies those inputs into three levels:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Level&lt;/i&gt;&lt;i&gt;&amp;#xA0;1&lt;/i&gt;&amp;#x2013; Observable inputs, such as quoted
 prices in active markets&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Level&lt;/i&gt;&lt;i&gt;&amp;#xA0;2&lt;/i&gt;&amp;#x2013; Inputs, other than the quoted
 prices in active markets, which are observable either directly or
 indirectly such as quoted prices for similar assets or liabilities;
 quoted prices in markets that are not active; or other inputs that
 are observable or can be corroborated by observable market data for
 substantially the full term of the instrument&amp;#x2019;s anticipated
 life&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Level&lt;/i&gt;&lt;i&gt;&amp;#xA0;3&lt;/i&gt;&amp;#x2013; Unobservable inputs in which
 there is little or no market data, which require the reporting
 entity to develop its own assumptions&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company measures its Series B convertible preferred shares
 warrant liability and term loan compound derivative liability at
 fair value on a recurring basis and these are classified as
 Level&amp;#xA0;3 liabilities. The fair value of the Series B preferred
 shares warrant liability was determined using an option-pricing
 model. The Company calculated the fair value of the term loan
 compound derivative liability by computing the difference between
 the fair value of the term loan with the compound derivative using
 the &amp;#x201C;with and without&amp;#x201D; method under the income
 approach, and the fair value of the term loan without the compound
 derivative. The valuation methodology and underlying assumptions
 are discussed further in Note 4.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The estimated fair value of the Term Loan was $5.7&amp;#xA0;million as
 of December&amp;#xA0;31, 2019 which approximates the carrying value and
 is classified as Level&amp;#xA0;3. The Company utilized a market yield
 analysis and income approach to estimate a value for the Term Loan.
 The key valuation assumptions used consist of the discount rate of
 14.5% and the probability of the occurrence of a change in control
 event of 10.0%.&lt;/p&gt;

 Realization of deferred tax assets is dependent upon the Company
 generating future taxable income, the timing and amount of which
 are uncertain. Accordingly, the deferred tax assets have been
 largely offset by a valuation allowance. The valuation allowance
 increased by approximately $0.8&amp;#xA0;million and $4.5&amp;#xA0;million
 for the years ended December&amp;#xA0;31, 2018 and December&amp;#xA0;31,
 2019, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 As of December&amp;#xA0;31, 2019, the Company had a net operating loss
 carryforwards for U.S. state income tax purposes of approximately
 $30.9&amp;#xA0;million, that expire in the year 2038, and for Ireland
 income tax purposes of approximately $4.0&amp;#xA0;million that never
 expire. As of December&amp;#xA0;31, 2019, the Company had U.S. federal
 research and development credit carryforwards of approximately
 $1.5&amp;#xA0;million, that expire in the year 2038, and U.S. state
 research and development credit carryforwards of approximately
 $2.4&amp;#xA0;million, that do not expire.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Utilization of the Company&amp;#x2019;s U.S. net operating loss and
 credit carryforwards may be subject to substantial annual
 limitation due to the ownership change limitations provided by the
 Internal Revenue Code and similar state provisions. Such annual
 limitation could result in the expiration of the U.S. net operating
 loss and credit carryforwards before utilization. To date, the
 Company has not performed an analysis to determine whether there
 would be a substantial annual limitation due to a change in
 ownership.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;b&gt;&lt;i&gt;Unrecognized Tax Benefits&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company&amp;#x2019;s policy is to include interest and penalties
 related to unrecognized tax benefits, if any, within the provision
 for taxes in the consolidated statements of operations and
 comprehensive loss. If the Company is eventually able to recognize
 its uncertain tax positions, the Company&amp;#x2019;s effective tax rate
 would be reduced. The Company currently has a full valuation
 allowance against its net deferred tax asset which would impact the
 timing of the effective tax rate benefit should any of these
 uncertain tax positions be favorably settled in the future.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company files income tax returns in Ireland, the U.S., and
 Malta. All of the Company&amp;#x2019;s tax years since 2015 remain open
 to examination.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 9px"&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt"&gt;

 Although it is reasonably possible that certain unrecognized tax
 benefits may increase or decrease within the next 12 months due to
 tax examination changes, settlement activities, expirations of
 statute of limitations or the impact on recognition and measurement
 considerations related to the results of published tax cases or
 other similar activities, the Company does not anticipate any
 significant changes to unrecognized tax benefits over the next 12
 months. During the years ended December&amp;#xA0;31, 2018 and
 December&amp;#xA0;31, 2019, no interest or penalties were required to
 be recognized relating to unrecognized tax benefits.&lt;/p&gt;

 In June 2018, the Company entered into a Research and Development
 Services Agreement, or Tollnine Agreement, with Tollnine, Inc., or
 Tollnine, a related-party of the Company, to provide research and
 development services to Tollnine. The Company&amp;#x2019;s Chief
 Executive Officer is also the Chief Executive Officer of Tollnine
 and two of the Company&amp;#x2019;s investors are also investors in
 Tollnine. As such, Tollnine was deemed to be a related-party. The
 Tollnine Agreement has an initial term of 3 years, to be
 automatically renewed for additional &lt;font style="WHITE-SPACE: nowrap"&gt;one-year&lt;/font&gt; terms unless terminated by
 either party. The services are to be provided at a price based on
 the costs incurred by the Company plus a &lt;font style="WHITE-SPACE: nowrap"&gt;mark-up&lt;/font&gt; equal to 10% of such costs.
 The Company recognizes revenue when Tollnine, as our customer,
 obtains control of promised goods or services, in an amount that
 reflects the consideration which the Company expects to receive in
 exchange for those goods or services. For the years ended
 December&amp;#xA0;31, 2018 and December&amp;#xA0;31, 2019, the Company
 recognized related-party revenues of $2.1&amp;#xA0;million and
 $4.8&amp;#xA0;million, respectively, under the Tollnine Agreement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 &lt;i&gt;Receivables due from Related-Party&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
 As of December&amp;#xA0;31, 2018, and 2019, the Company had outstanding
 related-party receivables from Tollnine of $0.9&amp;#xA0;million and
 $0.5&amp;#xA0;million, respectively.&lt;/p&gt;

 Financial instruments that potentially subject the Company to a
 concentration of credit risk consist primarily of cash. The Company
 maintains deposits in federally insured financial institutions in
 excess of federally insured limits. The Company is exposed to
 credit risk in the event of default by the financial institutions
 holding its cash. The Company has not experienced any losses on its
 deposits of cash.&lt;/p&gt;

 The Company&amp;#x2019;s future results of operations involve a number
 of other risks and uncertainties. Factors that could affect the
 Company&amp;#x2019;s future operating results and cause actual results
 to vary materially from expectations include, but are not limited
 to, uncertainty of results of clinical trials and reaching
 milestones, uncertainty of regulatory approval of the
 Company&amp;#x2019;s potential product candidates, uncertainty of market
 acceptance of the Company&amp;#x2019;s product candidates, competition
 from substitute products and larger companies, securing and
 protecting proprietary technology, strategic relationships and
 dependence on key individuals or sole-source suppliers.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 The Company&amp;#x2019;s product candidates require approvals from the
 FDA and comparable foreign regulatory agencies prior to commercial
 sales in their respective jurisdictions. There can be no assurance
 that any product candidates will receive the necessary approvals.
 If the Company was denied approval, approval was delayed or the
 Company was unable to maintain approval for any product candidate,
 it could have a materially adverse impact on the Company.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 Since commencing operations, none of the Company&amp;#x2019;s product
 candidates have received marketing approval from the U.S. Food and
 Drug Administration, or FDA, or any other federal, state, local or
 foreign governmental or regulatory authority and therefore the
 Company has not generated any revenue from drug product sales. The
 Company had an accumulated deficit of $72.8&amp;#xA0;million as of
 December&amp;#xA0;31, 2019 and management does not expect to experience
 positive cash flows in the foreseeable future. Based on
 management&amp;#x2019;s current plans, management believes cash of
 $9.0&amp;#xA0;million as of December&amp;#xA0;31, 2019, along with the
 $105.0&amp;#xA0;million of gross proceeds from the issuance of Series C
 convertible preferred shares in February 2020 (Note 13), are
 sufficient to fund operations through at least one year from the
 date of the issuance of these consolidated financial
 statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 Management expects to incur additional losses in the future to
 conduct product candidate research and development and to conduct
 &lt;font style="WHITE-SPACE: nowrap"&gt;pre-commercialization&lt;/font&gt;
 activities and recognizes the need to raise additional capital to
 fully implement its business plan. The Company intends to raise
 such capital through the sale of additional equity, debt financings
 or strategic alliances with third parties. However, there can be no
 assurance that the Company will be successful in acquiring
 additional funding at levels sufficient to fund its operations or
 on terms acceptable to the Company. If the Company is unsuccessful
 in its efforts to raise additional financing, the Company could be
 required to significantly reduce operating expenses and delay,
 reduce the scope of or eliminate some of its development programs
 or its future commercialization efforts, &lt;font style="WHITE-SPACE: nowrap"&gt;out-license&lt;/font&gt; intellectual property
 rights to its product candidates and sell unsecured assets, or a
 combination of the above, any of which may have a material adverse
 effect on the Company&amp;#x2019;s business, results of operations,
 financial condition and/or its ability to fund its scheduled
 obligations on a timely basis or at all.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 From time to time, new accounting pronouncements are issued by the
 Financial Accounting Standards Board, or FASB, or other standard
 setting bodies and adopted by the Company as of the specified
 effective date. Unless otherwise discussed, the impact of recently
 issued standards that are not yet effective will not have a
 material impact on the Company&amp;#x2019;s financial position or
 results of operations upon adoption.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In February 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; (Topic 842),
 &lt;i&gt;Leases&lt;/i&gt; (ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02).&lt;/font&gt; ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; requires an entity to
 recognize assets and liabilities arising from a lease for both
 financing and operating leases. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; will also require new
 qualitative and quantitative disclosures to help investors and
 other financial statement users better understand the amount,
 timing, and uncertainty of cash flows arising from leases. In
 November 2019, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2019-10,&lt;/font&gt; which extends the
 effective date of ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02&lt;/font&gt; for &lt;font style="WHITE-SPACE: nowrap"&gt;non-public&lt;/font&gt; business entities,
 including smaller reporting companies, to fiscal years beginning
 after December&amp;#xA0;15, 2020. The new standard is effective for the
 Company beginning January&amp;#xA0;1, 2021. Early adoption is
 permitted. The Company is currently evaluating the effects of the
 adoption of this guidance on its consolidated financial statements
 and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In June 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-13,&lt;/font&gt; &lt;i&gt;Financial
 Instruments-Credit Losses&lt;/i&gt; (Topic 326), which requires entities
 to measure all expected credit losses for financial assets held at
 the reporting date based on historical experience, current
 conditions, and reasonable and supportable forecasts. This replaces
 the existing incurred loss model and is applicable to the
 measurement of credit losses on financial assets measured at
 amortized cost. In February 2020, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2020-02&lt;/font&gt; and delayed the
 effective date of Topic 326 until fiscal year beginning after
 December&amp;#xA0;15, 2022. The new standard is effective for the
 Company beginning January&amp;#xA0;1, 2023. Early adoption is
 permitted. The Company is currently evaluating the effects of the
 adoption of this guidance on its consolidated financial statements
 and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 9pt"&gt;
 In December 2019, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2019-12,&lt;/font&gt; &lt;i&gt;Income Taxes&lt;/i&gt;
 (Topic 740): Simplifying the Accounting for Income Taxes, which is
 intended to simplify various aspects related to accounting for
 income taxes. The pronouncement is effective for fiscal years, and
 for interim periods within those fiscal years, beginning after
 December&amp;#xA0;15, 2021. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2019-12&lt;/font&gt; is effective for the Company
 beginning January&amp;#xA0;1, 2022. Early adoption is permitted. The
 Company is currently in the process of evaluating the effects of
 the adoption of this guidance on the Company&amp;#x2019;s financial
 statements and does not expect it to have a material impact on its
 consolidated financial statements.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 4pt"&gt;
 The Company records accruals for estimated costs of research,
 preclinical studies and clinical trials, and manufacturing
 development, which are a significant component of research and
 development expenses. A substantial portion of the Company&amp;#x2019;s
 ongoing research and development activities are conducted by
 third-party service providers, including contract research
 organizations, or CROs, and contract manufacturing organizations,
 or CMOs. The Company&amp;#x2019;s contracts with CROs generally include
 pass-through fees such as regulatory expenses, investigator fees,
 travel costs and other miscellaneous costs, including shipping and
 printing fees. The financial terms of these contracts are subject
 to negotiations, which vary from contract to contract and may
 result in payment flows that do not match the periods over which
 materials or services are provided to the Company under such
 contracts. The Company accrues the costs incurred under agreements
 with these third parties based on estimates of actual work
 completed in accordance with the respective agreements. The Company
 determines the estimated costs through discussions with internal
 personnel and external service providers as to the progress or
 stage of completion of the services and the agreed-upon fees to be
 paid for such services.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 6px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: ARIAL; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt"&gt;
 The Company makes significant judgments and estimates in
 determining the accrual balance at the end of each reporting
 period. As actual costs become known, the Company adjusts its
 accruals. Although the Company does not expect its estimates to be
 materially different from amounts actually incurred, the
 Company&amp;#x2019;s understanding of the status and timing of services
 performed relative to the actual status and timing of services
 performed may vary and could result in the Company reporting
 amounts that are too high or too low in any particular period. To
 assist in its estimates the Company relies upon the receipt of
 timely and accurate reporting from information provided as part of
 its clinical and &lt;font style="WHITE-SPACE: nowrap"&gt;non-clinical&lt;/font&gt; studies and other
 third-party vendors. Through December&amp;#xA0;31, 2019, there have
 been no material differences from the Company&amp;#x2019;s accrued
 estimated expenses to the actual clinical trial expenses. However,
 variations in the assumptions used to estimate accruals, including,
 but not limited to, the number of patients enrolled, the rate of
 patient enrollment, and the actual services performed, and related
 costs may vary from the Company&amp;#x2019;s estimates, resulting in
 adjustments to clinical trial expense in future periods. Changes in
 these estimates that result in material changes to the
 Company&amp;#x2019;s accruals could materially affect its financial
 position and results of operations.&lt;/p&gt;
