Organization and description of business | 1. Organization and description of business Overview Sagimet Biosciences Inc. (the Company) was incorporated in Delaware on December 19, 2006, as 3-V Biosciences, Inc. and is headquartered in San Mateo, California. The Company changed its name from 3-V Biosciences, Inc. to Sagimet Biosciences Inc. in August 2019. The Company is a clinical-stage biopharmaceutical company developing novel therapeutics called fatty acid synthase (FASN) inhibitors that target dysfunctional metabolic pathways in diseases resulting from the overproduction of the fatty acid, palmitate. Risks, uncertainties and going concern The Company is subject to certain risks and uncertainties, including, but not limited to changes in any of the following areas that the Company believes could have a material adverse effect on future financial position or results of operations: the availability of future financing; the ability to obtain regulatory approval and market acceptance of, and reimbursement for, the Company’s drug candidates if approved; the performance of third-party clinical research organizations and manufacturers; protection of the intellectual property; litigation or claims against the Company based on intellectual property, patent, product, regulatory or other factors; and the Company’s ability to attract and retain employees necessary to support commercial success. In addition, significant changes in the biotechnology industry or the approval of competitive products or therapies could adversely affect the Company’s development and operating results. As of June 30, 2023, the Company has relied on public and private equity and debt financings to fund its operations. The Company has incurred net losses and negative cash flows from operations since inception, including net losses of $13.4 million for the six months ended June 30, 2023 and $15.8 million for the six months ended June 30, 2022. For the six months ended June 30, 2023, and 2022, the Company had negative cash flows from operations of $12.8 million and $10.8 million, respectively. As of June 30, 2023, the Company had cash and cash equivalents of $18.5 million. The Company expects to incur additional losses and negative cash flows from operations for the next twelve months. The Company will require substantial additional capital to fund its research and development and ongoing operating expenses. On July 18, 2023, the Company closed on its initial public offering (IPO), in which it issued and sold 5,312,500 shares of Series A common stock, at a price to the public of $16.00 per share. The aggregate gross proceeds of the IPO were $96.4 million, inclusive of an additional 714,272 shares of Series A common stock sold upon the partial exercise of the underwriters’ purchase option. The Company received approximately $86.2 million in net proceeds after deducting underwriting discounts, commissions, and estimated offering expenses. See Note 13. As of August 21, 2023, the issuance date of these unaudited condensed financial statements, the Company expects that its cash and cash equivalents as of June 30, 2023, and total net proceeds from the IPO of $86.2 million will be sufficient to fund its operating expenses and capital expenditure requirements through at least 12 months from the issuance of these condensed financial statements. In the future, the Company may need to raise additional funds until it is able to generate sufficient revenues to fund its development activities. The Company’s future operating activities, coupled with its plans to raise capital or issue debt financing, may provide additional liquidity in the future, however these actions are not solely within the control of the Company and the Company is unable to predict the outcome of these actions to generate the liquidity ultimately required. Reverse stock split A one-for- 79.4784 Impact of COVID-19 pandemic on financial statements The 2019 novel coronavirus disease (COVID-19) and the related responses by public health and governmental authorities to contain and combat its outbreak and spread severely impacted the U.S. and world economies during the end of the first quarter of 2020 through the end of 2022. Moving forward, economic recessions, increased inflation and/or interest rates, including those brought on by the continued effects of the COVID-19 outbreak may have a negative effect on the Company’s operating results. Any prolonged disruption to the Company’s operations or workforce availability is likely to have a significant adverse effect on the Company’s results of operations and cash flows. All of the above may be exacerbated in the future as the COVID-19 outbreak and the governmental responses thereto continue. Unaudited interim financial information The accompanying condensed balance sheet as of June 30, 2023, the condensed statements of operations and comprehensive loss for the three and six months ended June 30, 2023 and 2022, the condensed statements of redeemable convertible preferred stock and stockholders’ deficit for the three and six months ended June 30, 2023 and 2022, the condensed statements of cash flows for the six months ended June 30, 2023 and 2022, and the related disclosures are unaudited. These unaudited condensed financial statements include all adjustments necessary, consisting of only normal recurring adjustments, to fairly state the financial position and the results of the Company’s operations and cash flows for interim periods in accordance with accounting principles generally accepted in the United States of America (GAAP). Interim period results are not necessarily indicative of results of operations or cash flows for a full year or any subsequent interim period. The condensed balance sheet as of December 31, 2022 has been derived from the audited financial statements of the Company. The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements included in the final prospectus filed pursuant to Rule 424(b)(4) under the Securities Act with the Securities and Exchange Commission (SEC) on July 17, 2023. |

Summary of significant accounting policies | 2. Summary of significant accounting policies Basis of presentation The financial statements and accompanying notes have been prepared in accordance with GAAP and the requirements of the SEC for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. These condensed financial statements have been prepared on the same basis as the annual financial statements included in the final prospectus filed pursuant to Rule 424(b)(4) under the Securities Act with the SEC on July 17, 2023. In the Company’s opinion, the information furnished in these condensed financial statements reflects all adjustments, all of which are of a normal and recurring nature necessary for a fair presentation of the financial position and results of operations for the reported interim periods. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and reported amounts of expenses during the reporting period. Such estimates include accruals of research and development expenses, accrued costs for services rendered in connection with third-party contractor clinical trial activities, preferred stock, common stock and stock option valuations and stock-based compensation. On an ongoing basis, the Company evaluates its estimates and judgments, which are based on historical and anticipated results and trends and on various other assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. Significant Accounting Policies The Company’s significant accounting policies are disclosed in the audited financial statements for the year ended December 31, 2022, and the unaudited financial statements as of March 31, 2023, filed with the SEC as part of the final prospectus filed pursuant to Rule 424(b)(4) under the Securities Act with the SEC on July 17, 2023. Since the date of those financial statements, there have been no changes to the Company’s significant accounting policies except as disclosed below in recently adopted accounting pronouncements. Marketable securities The Company classifies its marketable debt securities as available-for-sale and records such assets at estimated fair value in the balance sheets. The Company adopted Accounting Standards Update (ASU) No. 2016-13, Financial Instruments Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments The Company had no short-term investments in marketable securities as of June 30, 2023. Deferred financing costs Deferred financing costs, consisting of legal, accounting and other fees and costs relating to the Company’s IPO are capitalized and recorded on the balance sheets. The deferred financing costs will be offset against the proceeds received upon the closing of the IPO. As of June 30, 2023, there were $2.6 million of deferred financing costs capitalized. On March 21, 2022, the Company withdrew its prior Registration Statement on Form S-1 initially filed with the SEC on April 16, 2021. Concurrently, all of the deferred financing costs of $1.4 million capitalized as of December 31, 2021 were expensed within operating expenses in the unaudited condensed statement of operations and comprehensive loss for the six months ended June 30, 2022, in accordance with the Company’s policy to write off all deferred financing costs within operating expenses in the Company’s unaudited condensed statements of operations and comprehensive loss in the event that the Company’s plans for an IPO are terminated. Revenue recognition The Company enters into collaboration and licensing arrangements that generally contain multiple elements or deliverables, which may include (1) licenses to the Company’s technology, (2) research and development activities performed for the collaboration partner, (3) participation on joint steering committees (JSCs), and (4) the manufacturing of clinical or preclinical material. Payments pursuant to these arrangements include milestone payments upon achieving significant development events, research and development reimbursements, sales milestones, and royalties on future drug sales. Variable consideration is constrained until it is probable that the revenue is not at a significant risk of reversal in a future period. In determining the appropriate amount of revenue to be recognized for the components of the arrangements that are within the scope of Accounting Standards Codification, Topic 606, Revenue from Contracts with Customers At the inception of each arrangement that includes milestone payments, the Company evaluates whether the milestones are considered probable of being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each subsequent reporting period, the Company reevaluates the probability of achievement of all milestones subject to constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment. For arrangements that include sales-based royalties or milestone payments, for which the license is deemed to be the predominant item, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). In January 2022, Ascletis BioScience Co. Ltd. (Ascletis) initiated dosing of a Phase 3 trial for recurrent glioblastoma multiforme (GBM), potentially triggering a $2.0 million development milestone payment, net of applicable taxes, under the license agreement. Due to the uncertainty around the payment of the milestone and ongoing discussions with Ascletis around the form and amount of consideration related to the milestone, the Company concluded it was probable that a significant reversal of the revenue related to the milestone would occur, and therefore, no revenue was recognized. The Company and Ascletis concluded their discussions regarding the payment of the milestone in July 2023. The Company invoiced Ascletis for the milestone payment, with payment due before the end of August 2023. See Note 13.

Fair value measurements and fair value of financial instruments | 3. Fair value measurements and fair value of financial instruments The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows: Level 1— Level 2— Level 3— As of June 30, 2023 and December 31, 2022, financial assets measured at fair value on a recurring basis consist of cash and cash equivalents. The carrying amount of cash and cash equivalents was $18.5 million and $0.2 million as of June 30, 2023 and December 31, 2022, respectively, which approximates the fair value and was determined based upon Level 1 inputs. The fair value of short-term investments is based upon market prices quoted on the last day of the fiscal period or other observable market inputs. The Company obtains pricing information from its investment manager and generally determines the fair value of investment securities using standard observable inputs, including reported trades, broker/dealer quotes, bids and/or offers. The carrying values of the Company’s accounts payable and accrued expenses and other current liabilities approximate their fair values due to the short-term nature of these liabilities. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. The Company’s Level 3 liability that is measured at fair value on a recurring basis consists of the redeemable convertible preferred stock warrant liability. Marketable securities, all of which are classified as available-for-sale securities, consisted of the following (in thousands): As of December 31, 2022 Amortized Unrealized Unrealized Estimated cost Gains Losses Fair Value Commercial paper $ 15,950 $ — $ — $ 15,950 Corporate debt securities 12,286 — (65) 12,221 U.S. Treasury securities 4,035 — (19) 4,016 Total $ 32,271 $ — $ (84) $ 32,187 There were no investments in marketable securities as of June 30, 2023.

There were no transfers within the hierarchy during the periods presented. Redeemable Convertible Preferred Stock Warrant Liability In connection with a note payable entered into on April 10, 2015, which was repaid in full in May 2019, the Company issued 79,545 Series D redeemable convertible preferred stock warrants. See Note 9. The Company estimates the fair value of the Redeemable Convertible Preferred Stock Warrant Liability using an option pricing model and assumptions that are based on the individual characteristics of the warrants on the valuation date, as well as assumptions for fair value of the underlying redeemable convertible preferred stock, expected volatility, expected life, dividends and risk-free interest rate. As of June 30, 2023, the fair value of the Redeemable Convertible Preferred Stock Warrant Liability was determined to be $5 thousand assuming a volatility rate of 93.3%, an expected term of 1.78 years, no dividends, and a risk-free interest rate of 4.57%. As of December 31, 2022, the fair value of the Redeemable Convertible Preferred Stock Warrant Liability was determined to be $4 thousand assuming a volatility rate of 97.3%, an expected term of 2.28 years, no dividends, and a risk-free interest rate of 4.36%. For the change in fair value of the Redeemable Convertible Preferred Stock Warrant Liability, the Company recorded other income of $1 thousand and other expense of $1 thousand for the three and six months ended June 30, 2023, respectively, and other income of $2 thousand for the six months ended June 30, 2022 in its unaudited condensed statement of operations and comprehensive loss. There was no change in fair value of Redeemable Convertible Preferred Stock Warrant Liability in the three months ended June 30, 2022. |

Related parties | 6. Related parties Ascletis BioScience Co. Ltd In January 2019, the Company entered into a license agreement that became effective in February 2019 with Ascletis, a subsidiary of Ascletis Pharma Inc. (Ascletis Pharma), biotechnology company incorporated in the Cayman Islands and headquartered in Hangzhou, China and a Company investor. The parties entered into this agreement with the intention to develop, manufacture, and commercialize the Company’s proprietary FASN inhibitor, denifanstat. Under the terms of the license agreement, the Company granted Ascletis and its affiliates an exclusive, royalty-bearing sublicensable right and license under the Company’s intellectual property to develop, manufacture, commercialize and otherwise exploit denifanstat and other products containing denifanstat-related compounds in Greater China, consisting of the People’s Republic of China, Hong Kong, Macau and Taiwan. The Company will bear all expenses related to development activities in Greater China as part of a global Phase 2 trial, except for clinical operations and regulatory staff provided by Ascletis. The Company conducted all development activities in connection with the FASCINATE-1 Phase 2 clinical trial in the United States and Greater China at its sole expense, except for certain in-kind contributions by Ascletis in Greater China. Ascletis is solely responsible for all development activities in connection with obtaining and maintaining regulatory approvals for denifanstat in Greater China. The Company received $28.1 thousand as reimbursement pursuant to the license agreement for Greater China patent prosecution costs during the six months ended June 30, 2022. The Company did not receive any reimbursements pursuant to the license agreement for Greater China patent prosecution costs during the six months ended June 30, 2023. The Company is eligible to receive development and commercial milestone payments from Ascletis in aggregate of up to $122.0 million as well as tiered royalties ranging from percentages in the high single digits to mid-teens on future net sales of denifanstat, which is referred to as ASC40 in Greater China. Ascletis Pharma, through a subsidiary, also led the Series E preferred stock financing in February 2019. There were no payments made to Ascletis during the six months ended June 30, 2023 or 2022. This license and Phase 2 research and development services components of this agreement are representative of a relationship with a customer and therefore are subject to ASC 606. In January 2022, Ascletis initiated dosing of a Phase 3 trial for recurrent GBM, potentially triggering a $2.0 million development milestone payment, net of applicable taxes, under the license agreement. Due to the uncertainty around the payment of the milestone and ongoing discussions with Ascletis around the form and amount of consideration related to the milestone, the Company concluded it was probable that a significant reversal of the revenue related to the milestone would occur, and therefore, no revenue was recognized. The Company and Ascletis concluded their discussions regarding the milestone in July 2023. The Company invoiced Ascletis for the milestone payment, with payment due before the end of August 2023.

Commitments and contingencies | 7. Commitments and contingencies Facility lease agreement On March 12, 2019, the Company executed a 38-month non-cancelable operating lease agreement for 3,030 square feet of office space for its headquarters facility which commenced April 1, 2019. The lease provides for monthly lease payments of approximately $12 thousand with annual increases. On December 20, 2021, the lease agreement was amended to extend the term of the lease through June 2024. The Company has accounted for the lease as an operating lease. Operating lease cost for the three months ended June 30, 2023 and 2022 was $37 thousand and $38 thousand, respectively, and for the six months ended June 30, 2023 and 2022 was $74 thousand and $75 thousand, respectively. The following are schedules by year of future maturities of the Company’s operating lease liabilities (in thousands): June 30, 2023 Remainder of 2023 $ 66 2024 79 Total lease payments 145 Less: interest (5) Total $ 140 December 31, 2022 2023 $ 157 2024 80 Total lease payments 237 Less: interest (26) Total $ 211 Supplemental cash flow information related to leases was as follows (in thousands): Six months ended June 30, Six months ended June 30, 2023 2022 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 78 $ 79 The weighted-average remaining lease term and discount rate related to the Company’s lease liabilities as of June 30, 2023 and December 31, 2022 were 10.3 months and 7% and 1.2 years and 7%, respectively. The Company’s lease discount rate is based on estimates of its incremental borrowing rate, as the discount rate implicit in the Company’s lease cannot be readily determined. As the Company does not have any outstanding debt, the Company estimates the incremental borrowing rate based on its estimated credit rating and available market information. Guarantees and indemnifications In the normal course of business, the Company enters into agreements that contain a variety of representations and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future. In addition, the Company has entered into indemnification agreements with members of its board of directors and its executive officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. As of June 30, 2023, the Company does not have any material indemnification claims that were probable or reasonably possible and consequently has not recorded related liabilities. Legal The Company is not party to any material legal proceedings at this time. From time to time, the Company may become involved in various legal proceedings that arise in the ordinary course of its business. |

The warrants have a term of 10 years and are exercisable in whole or in part, at any time on or before the expiration date of April 10, 2025. At the time of issuance, the fair value of the Redeemable Convertible Preferred Stock Warrant Liability was determined using an option pricing model and assumptions that are based on the individual characteristics of the warrant on the valuation date, as well as assumptions for fair value of the underlying redeemable convertible preferred stock, expected volatility, expected life, dividends and risk-free interest rate. The Series D redeemable convertible preferred stock warrant has no voting rights, or other rights as a stockholder of the Company. The warrant is subject to adjustment in the event of any diluting dividends or distributions of the common stock, or any stock split, reverse stock split, recapitalization, reorganization or similar transaction. Upon any reclassification, exchange, substitution or other event, the number and or class of the securities and property that the holder would have received for the shares if this warrant had been issued immediately before such event will be adjusted. The Company closed on its IPO on July 18, 2023 (see Note 13). Subsequently, the expiration date of the Series D Redeemable convertible preferred stock warrant was automatically extended until July 18, 2026, the third anniversary date of the effective date of the Company’s IPO. If the warrant has not been exercised prior to the expiration date, the warrant will be deemed to have been automatically exercised on the expiration date by cashless conversion.

Stock-based compensation In 2007, the Company adopted the 2007 Equity Incentive Plan, as amended, which allowed for the granting of incentive stock options (ISOs) and non-statutory stock options (NSOs) to the employees, members of the Company’s board of directors, and consultants of the Company. In 2017, the 2007 Equity Incentive Plan expired pursuant to its terms and the Company adopted the 2017 Equity Incentive Plan (2017 Plan) which allows for the granting of ISOs and NSOs as well as stock appreciation rights, restricted stock awards, restricted stock units and other stock awards to employees, members of the Company’s board of directors and consultants. ISOs may be granted only to Company’s employees, including officers and directors who are also employees. NSOs may be granted to employees, directors and consultants. As of June 30, 2023 and December 31, 2022, 0 and 181,191 shares are available for future grant under the 2017 Plan, respectively. Options under the 2017 Plan may be granted for periods of up to ten years and at prices no less than 100% of the estimated fair value of the shares on the date of grant as determined by the Company’s board of directors, provided, however, that an ISO granted to a 10% stockholder shall not have an exercise price that is less than 110% of the estimated fair value of the shares on the date of grant and shall not have a contractual term longer than five years. The 2023 Stock Option and Incentive Plan (2023 Plan), was adopted by the board of directors on June 22, 2023, approved by the Company’s stockholders on July 4, 2023 and became effective on July 13, 2023. The 2023 Plan replaced the 2017 Plan. See Note 13. The following table summarizes stock option transactions (in thousands, except share and per share data): Weighted- Number of Average Shares Weighted- Remaining Underlying Average Contractual Aggregate Outstanding Exercise Term Intrinsic Options Price (in Years) Value Outstanding, January 1, 2023 3,190,450 $ 7.10 8.1 $ 3,998 Options granted 585,919 $ 13.51 Outstanding, June 30, 2023 3,776,369 $ 7.98 7.92 $ 21,313 Shares vested and exercisable as of June 30, 2023 1,671,475 $ 6.75 6.47 $ 11,411 The aggregate intrinsic value is calculated as the difference between the option exercise price and the estimated fair value of the underlying common stock. Time-based options The Company may award time-based options which vest and become exercisable, subject to the participant’s continued employment or service through the applicable vesting date. Options granted have various vesting schedules including some that vest immediately and some that vest over four years. The following table summarizes time-based stock option activity: Number of Shares Underlying Weighted- Outstanding Average Options Exercise Price Outstanding, January 1, 2023 2,570,708 $ 7.56 Options granted 585,919 13.51 Outstanding, June 30, 2023 3,156,627 $ 8.01 Shares vested and exercisable as of June 30, 2023 1,618,051 The total fair value of the time-based shares vested during the six months ended June 30, 2023 was $0.8 million. As of June 30, 2023, there was $13.3 million of total unrecognized compensation cost related to the awards. The cost is being recognized over a remaining weighted-average period of 3.2 years. Performance-based options The Company may award grants of performance-based options to eligible individuals. Performance-based options vest based on performance measures against predetermined objectives that could include successful completion of qualified equity offerings or announced topline results for clinical trials and positive clinical results over a specified performance period. The total number of shares underlying outstanding options was 619,742 with a weighted-average exercise price of $6.38 as of December 31, 2022 June 30, 2023 The total fair value of the performance-based shares vested during the six months ended June 30, 2023 was $11 thousand. As of the six months ended June 30, 2023, there was no unrecognized compensation cost related to the awards because it was improbable that the performance conditions would be met. The cost is being recognized over a remaining weighted-average period of less than one year. The Company has recorded aggregate stock-based compensation expense related to the issuance of stock option awards to employees and non-employees in the unaudited condensed statements of operations and comprehensive loss as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 General and administrative expense $ 856 $ 219 $ 1,454 $ 443 Research and development expense 201 164 370 327 Total stock-based compensation expense $ 1,057 $ 383 $ 1,824 $ 770 The expected term of the stock options represents the average of the contractual term of the options and the weighted-average expected vesting period. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility rate was based on the historical volatilities of comparable companies in the Company’s industry. The Company has never declared or paid any cash dividends and does not presently plan to pay cash dividends in the foreseeable future. Consequently, the Company used an expected dividend yield of zero. The fair value of each award granted was estimated on the date of grant using the Black-Scholes option pricing model using the following assumptions: Six Months Ended Six Months Ended June 30, 2023 June 30, 2022 Expected volatility 89 - 91 % 88 - 90 % Risk-free interest rate 3.6 % 3.0 % Dividend yield — — Expected term 5.0 - 7.0 years 5.4 - 7.0 years |

Income taxes | 12. Income taxes The provision for income taxes primarily relates to projected federal and state income taxes calculated on the projected taxable income for the period. To determine the quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is generally based on expected annual income as well as statutory tax rates in the various jurisdictions in which the Company operates. In addition, the tax effects of certain significant or unusual items are recognized discretely in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter. As per ASC 740-270, the Company’s interim tax provision is computed based on the estimated annual effective tax rate approach. The estimated annual effective tax rate approach is used to determine the tax related to ordinary income unless certain exceptions apply. The Company records a valuation allowance to reduce its deferred taxes to the amount it believes is more likely than not to be realized. In making such determination, the Company considers all available positive and negative evidence quarterly, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Forming a conclusion that a valuation allowance is not required is difficult when there is negative evidence such as cumulative losses in recent years. Based upon the Company’s review of all positive and negative evidence, the Company continues to have a full valuation allowance on its deferred tax assets as of June 30, 2023. The Company accounts for the uncertainty in income taxes by utilizing a comprehensive model for the recognition, measurement, presentation and disclosure in financial statements of any uncertain tax positions that have been taken or are expected to be taken on an income tax return. There have been no changes in the estimated uncertain positions or tax benefits recorded as of December 31, 2022. |

Subsequent events The Company has evaluated subsequent events for financial statement purposes occurring through August 21, 2023, the date when these financial statements are available to be issued. Reverse stock split A one-for- 79.4784 Reclassification of common stock In connection with the effectiveness of the Company’s eleventh amended and restated certificate of incorporation (the Charter), on July 18, 2023, each share of the Company’s common stock issued and outstanding became reclassified as one share of Series A common stock. Any stock certificate that immediately prior to July 18, 2023 represented shares of the Corporation’s common stock is deemed to represent shares of Series A common stock, without the need for surrender or exchange thereof. Initial public offering On July 18, 2023, the Company closed its IPO, in which it issued and sold 5,312,500 shares of Series A common stock at a price to the public of $16.00 per share. The aggregate gross proceeds of the IPO were $96.4 million, inclusive of an additional 714,272 shares of Series A common stock sold upon the partial exercise of the underwriters’ purchase option. The Company received approximately $86.2 million in net proceeds after deducting underwriting discounts, commissions, and estimated offering expenses. In connection with the IPO, the Company’s outstanding convertible preferred stock automatically converted into 15,117,912 shares of Series A and 1,520,490 shares of Series B common stock. The rights of the holders of Series A common stock and Series B common stock are substantially identical, except with respect to voting and conversion. Each share of Series A common stock is entitled to one vote and shares of Series B common stock are non-voting, except as may be required by law. Each share of Series B common stock may be converted at any time into one share of Series A common stock at the option of its holder, subject to the ownership limitations provided for in the Charter. 2023 Stock Option and Incentive Plan The 2023 Plan, was adopted by the board of directors on June 22, 2023, approved by the Company’s stockholders on July 4, 2023 and became effective on July 13, 2023. The 2023 Plan replaced the 2017 Plan. The 2023 Plan permits the granting of both options to purchase Series A common stock intended to qualify and not qualify as incentive stock options under Section 422 of the Code. The number of shares initially reserved for issuance under the 2023 Plan was 2,585,968, which will automatically increase on January 1, 2024 and each January 1 thereafter, by 4% of the outstanding number of shares of our Series A common stock on the immediately preceding December 31 or a lesser number of shares as determined by the compensation committee of the board of directors. 2023 Employee Stock Purchase Plan The 2023 Employee Stock Purchase Plan (the ESPP), was adopted by the board of directors on June 22, 2023, approved by the Company’s stockholders on July 4, 2023 and became effective on July 13, 2023. A total of 215,497 shares of Series A common stock were initially reserved for issuance under this plan, which will automatically increase on January 1, 2024 and each January 1 thereafter through January 1, 2033, by the least of (i) 215,497 shares of Series A common stock, (ii) 1% of the outstanding number of shares of the Company’s Series A common stock on the immediately preceding December 31 or (iii) such lesser number of shares of Series A common stock as determined by the administrator of the ESPP. Ascletis In January 2022, Ascletis initiated dosing of a Phase 3 trial for recurrent GBM, potentially triggering a $2.0 million milestone payment, net of applicable taxes, under the license agreement. The parties were in discussions regarding the form and amount of consideration related to this milestone until February 2023. Thereafter the Company and Ascletis discussed whether amendment or waiver of the milestone payment could benefit both parties; these discussions concluded in July 2023. The Company invoiced Ascletis for the milestone payment, with payment due before the end of August 2023. Assignment and Assumption Agreement In July 2023, the Company entered into an Assignment and Assumption Agreement with Ascletis and Ascletis’ affiliate Gannex under which Ascletis, while remaining responsible for performance under the license agreement (see Note 6), assigned all of its rights and obligations under the license agreement to Gannex and Gannex assumed such rights and obligations, effective as of October 2019. |

Summary of significant accounting policies | |
Basis of presentation | Basis of presentation The financial statements and accompanying notes have been prepared in accordance with GAAP and the requirements of the SEC for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. These condensed financial statements have been prepared on the same basis as the annual financial statements included in the final prospectus filed pursuant to Rule 424(b)(4) under the Securities Act with the SEC on July 17, 2023. In the Company’s opinion, the information furnished in these condensed financial statements reflects all adjustments, all of which are of a normal and recurring nature necessary for a fair presentation of the financial position and results of operations for the reported interim periods. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and reported amounts of expenses during the reporting period. Such estimates include accruals of research and development expenses, accrued costs for services rendered in connection with third-party contractor clinical trial activities, preferred stock, common stock and stock option valuations and stock-based compensation. On an ongoing basis, the Company evaluates its estimates and judgments, which are based on historical and anticipated results and trends and on various other assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. |
Significant Accounting Policies | Significant Accounting Policies The Company’s significant accounting policies are disclosed in the audited financial statements for the year ended December 31, 2022, and the unaudited financial statements as of March 31, 2023, filed with the SEC as part of the final prospectus filed pursuant to Rule 424(b)(4) under the Securities Act with the SEC on July 17, 2023. Since the date of those financial statements, there have been no changes to the Company’s significant accounting policies except as disclosed below in recently adopted accounting pronouncements. |
Marketable securities | Marketable securities The Company classifies its marketable debt securities as available-for-sale and records such assets at estimated fair value in the balance sheets. The Company adopted Accounting Standards Update (ASU) No. 2016-13, Financial Instruments Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments The Company had no short-term investments in marketable securities as of June 30, 2023. |
Deferred financing costs | Deferred financing costs Deferred financing costs, consisting of legal, accounting and other fees and costs relating to the Company’s IPO are capitalized and recorded on the balance sheets. The deferred financing costs will be offset against the proceeds received upon the closing of the IPO. As of June 30, 2023, there were $2.6 million of deferred financing costs capitalized. On March 21, 2022, the Company withdrew its prior Registration Statement on Form S-1 initially filed with the SEC on April 16, 2021. Concurrently, all of the deferred financing costs of $1.4 million capitalized as of December 31, 2021 were expensed within operating expenses in the unaudited condensed statement of operations and comprehensive loss for the six months ended June 30, 2022, in accordance with the Company’s policy to write off all deferred financing costs within operating expenses in the Company’s unaudited condensed statements of operations and comprehensive loss in the event that the Company’s plans for an IPO are terminated. |
Revenue recognition | Revenue recognition The Company enters into collaboration and licensing arrangements that generally contain multiple elements or deliverables, which may include (1) licenses to the Company’s technology, (2) research and development activities performed for the collaboration partner, (3) participation on joint steering committees (JSCs), and (4) the manufacturing of clinical or preclinical material. Payments pursuant to these arrangements include milestone payments upon achieving significant development events, research and development reimbursements, sales milestones, and royalties on future drug sales. Variable consideration is constrained until it is probable that the revenue is not at a significant risk of reversal in a future period. In determining the appropriate amount of revenue to be recognized for the components of the arrangements that are within the scope of Accounting Standards Codification, Topic 606, Revenue from Contracts with Customers At the inception of each arrangement that includes milestone payments, the Company evaluates whether the milestones are considered probable of being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each subsequent reporting period, the Company reevaluates the probability of achievement of all milestones subject to constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment. For arrangements that include sales-based royalties or milestone payments, for which the license is deemed to be the predominant item, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). In January 2022, Ascletis BioScience Co. Ltd. (Ascletis) initiated dosing of a Phase 3 trial for recurrent glioblastoma multiforme (GBM), potentially triggering a $2.0 million development milestone payment, net of applicable taxes, under the license agreement. Due to the uncertainty around the payment of the milestone and ongoing discussions with Ascletis around the form and amount of consideration related to the milestone, the Company concluded it was probable that a significant reversal of the revenue related to the milestone would occur, and therefore, no revenue was recognized. The Company and Ascletis concluded their discussions regarding the payment of the milestone in July 2023. The Company invoiced Ascletis for the milestone payment, with payment due before the end of August 2023. See Note 13. |
Emerging growth company status | Emerging growth company status The Company is an emerging growth company (EGC) as defined in the Jumpstart Our Business Startups Acts of 2012, as amended (the JOBS Act), and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not EGCs. The Company may take advantage of these exemptions until it is no longer an EGC under Section 107 of the JOBS Act and has elected to use the extended transition period for complying with new or revised accounting standards. As a result of this election, the Company’s financial statements may not be comparable to companies that comply with public company Financial Accounting Standards Board (FASB) standards’ effective dates. |
