Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Nature of the Business | Nature of the Business Theseus Pharmaceuticals, Inc. (“Theseus” or the “Company”) is a clinical-stage biopharmaceutical company focused on improving the lives of cancer patients through the discovery, development and commercialization of transformative targeted therapies. The Company was incorporated in December 2017 under the laws of the State of Delaware, and its principal offices are in Cambridge, Massachusetts. Basis of Presentation The Company’s condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The accompanying condensed consolidated financial statements and footnotes to the condensed consolidated financial statements have been prepared on the same basis as the most recently audited annual consolidated financial statements and, in the opinion of management, reflect all normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of September 30, 2023 and the results of its operations and its cash flows for the interim periods presented. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods, or any future year or period. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2022. Liquidity The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including but not limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. The Company’s product candidate and development programs will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Because of the numerous risks and uncertainties associated with product development, the Company is unable to predict the timing or amount of increased expenses, or when or if the Company will be able to achieve or maintain profitability. Even if the Company is able to generate revenue from product sales, the Company may not become profitable. If the Company fails to become profitable or is unable to sustain profitability on a continuing basis, then the Company may be unable to continue its operations at planned levels and be forced to reduce or terminate its operations. The Company expects to incur substantial operating losses and negative cash flows from operations for the foreseeable future. In accordance with ASC 205-40, Going Concern , the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the condensed consolidated financial statements are issued. As of September 30, 2023, the Company had an accumulated deficit of $155.1 million. During the nine months ended September 30, 2023, the Company incurred a loss of $42.9 million and utilized $39.7 million of cash in operations. The Company expects to continue to generate operating losses for the foreseeable future. The Company expects that its cash, cash equivalents, and marketable securities of $225.4 million at September 30, 2023 will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next twelve months from issuance of the accompanying condensed consolidated financial statements. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The significant accounting policies and estimates used in the preparation of the accompanying condensed consolidated financial statements are described in the Company’s audited consolidated financial statements, which were included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission (“SEC”) on March 9, 2023 (“Annual Report”). There have been no material changes in the Company’s significant accounting policies during the nine months ended September 30, 2023, except as noted below. Unaudited Interim Financial Information The accompanying condensed consolidated financial statements and the accompanying notes as of September 30, 2023 and December 31, 2022 and for the three and nine months ended September 30, 2023 and 2022 are unaudited. The condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of September 30, 2023 and the results of its operations for the three and nine months ended September 30, 2023 and 2022 and its cash flows for the nine months ended September 30, 2023 and 2022. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting periods. Estimates and judgments are based on historical information and other market-specific or various relevant assumptions, including in certain circumstances, future projections, that management believes to be reasonable under the circumstances. Actual results could differ materially from estimates. Significant estimates and assumptions are used for, but not limited to, the accruals for research and development expenses. Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and marketable securities. Periodically, the Company maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and have not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Such deposits have and will continue to exceed federally insured limits. The Company has not experienced any losses on its cash deposits. The Company’s short-term and long-term marketable securities are invested in high grade securities with limited concentration in any one issuer, and as a result, the Company believes represent minimal credit risk. Recently Issued and Adopted Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its condensed consolidated financial statements and disclosures. In June 2016, the FASB issued ASU No. 2016‑13, Financial Instruments—Credit Losses (Topic 326)—Measurement of Credit Losses on Financial Instruments , which has been subsequently amended (“ASU 2016‑13”). This updated accounting guidance significantly changes the impairment model for most financial assets and certain other instruments. ASU 2016-13 will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, which will generally result in earlier recognition of allowances for credit losses on trade receivables, loans and other financial instruments. This update is effective for the Company’s fiscal year beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this new standard on January 1, 2023, and the adoption had no material impact on the Company's consolidated financial statements. |

Share-Based Payment Arrangement [Abstract] | |
Stock-Based Compensation | Stock-Based Compensation Equity Incentive Plans In September 2021, the Company adopted the Theseus Pharmaceuticals, Inc. 2021 Equity Incentive Plan (the “2021 Plan”), which replaced the 2018 Stock Incentive Plan (the “2018 Plan”) and allows for the issuance of stock options, restricted stock awards, restricted stock units (“RSUs”), and other types of equity awards. No further awards were made under the 2018 Plan as of the effective date of the 2021 Plan. Any options or awards outstanding under the 2018 Plan are governed by their existing terms. On the first day of each fiscal year of the Company during the term of the Plan, commencing on January 1, 2023 and ending on (and including) January 1, 2031, the aggregate number of Common Shares that may be issued under the Plan shall automatically increase by a number equal to the lesser of (a) five percent (5%) of the total number of Common Shares actually issued and outstanding on the last day of the preceding fiscal year, or (b) a number of Common Shares determined by the Board. As of September 30, 2023 and December 31, 2022, the number of shares of common stock reserved for issuance were 11,021,034 and 9,132,930 shares, respectively. Of those shares reserved for issuance, there were 1,972,328 and 1,843,494 shares available for future grant as of September 30, 2023 and December 31, 2022, respectively. The 2021 Plan is administered by the Board (or its compensation committee), and the exercise prices, vesting and other restrictions for the awards are determined at the discretion of the Board, except that the exercise price per share of stock options may not be less than 100% of the fair market value of the common stock on the date of grant. Stock options awarded under the 2021 Plan expire ten years after the grant date unless the Board sets a shorter term. Stock options and restricted stock units granted to employees and non-employees typically vest over four years. Shares of restricted common stock awards granted to employees, officers, members of the Board, advisors, and consultants of the Company typically vest over five years. Certain executives who are option holders are able to early exercise stock option awards prior to full satisfaction of the vesting conditions. If and when this occurs, the executive receives restricted common stock upon exercise of the option, and the shares remain subject to the Company’s right of repurchase, at exercise price, until the remaining vesting terms are met. During the year ended December 31, 2021, options to purchase 345,930 shares of common stock were exercised early. As of September 30, 2023 and December 31, 2022, the Company recognized $0.6 million and $0.8 million, respectively, as a liability related to the early exercise. The amount of remaining unvested shares related to the early exercise as of September 30, 2023 and December 31, 2022 were 136,931 and 201,793 shares, respectively. There were no additional early exercises of options during the nine months ended September 30, 2023. Employee Stock Purchase Plan In September 2021, the Board adopted, and its stockholders approved, the 2021 Employee Stock Purchase Plan (the "ESPP"), which became effective on October 6, 2021. The number of shares of common stock initially reserved for issuance under the ESPP was 400,000. In addition, on the first day of each fiscal year of the Company during the term of the ESPP, commencing on January 1, 2023 and concluding on January 1, 2041, the aggregate number of shares of common stock reserved for issuance under the ESPP shall automatically increase by a number equal to the lesser of (i) one percent (1%) of the total number of shares of common stock actually issued and outstanding on the last day of the preceding fiscal year, and (ii) a number of shares of common stock determined by the Board. The ESPP enables eligible employees to purchase shares of common stock of the Company at the end of each offering period at a price equal to 85% of the lower of the fair market value of the common stock at the commencement date of each offering period or the relevant date of purchase. As of September 30, 2023, the number of shares of common stock that may be issued under the ESPP is 730,682. Stock Option Valuation The assumptions that the Company used in Black-Scholes option-pricing model to determine the grant-date fair value of stock options granted are as follows: FOR THE NINE MONTHS ENDED FOR THE YEAR ENDED Risk-free interest rate 3.54% - 4.03% 1.60% - 4.20% Expected term (in years) 5.50 - 6.08 1.03 - 6.08 Expected volatility 87.82% - 89.15% 78.00% - 90.51% Expected dividend yield 0% 0% A summary of option activity under the 2021 Plan during the nine months ended September 30, 2023, is as follows (in thousands except share, per share data and contractual terms): SHARES WEIGHTED-AVERAGE WEIGHTED-AVERAGE AGGREGATE Outstanding as of December 31, 2022 7,257,786 $ 5.95 8.58 $ 10,751 Granted 1,700,130 11.17 Exercised (17,880) 2.70 Forfeited (224,698) 11.37 Expired (1,354) 11.04 Outstanding as of September 30, 2023 8,713,984 $ 6.84 8.06 4,367 Options vested and exercisable as of September 30, 2023 4,135,826 $ 5.03 7.61 $ 3,254 The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the Company’s common stock. The weighted-average per share grant date fair value of options granted during the nine months ended September 30, 2023 and 2022 was $8.44 and $6.80, respectively. As of September 30, 2023, there was $27.8 million of unrecognized stock-based compensation expense related to unvested stock options. The unrecognized stock-based compensation expense is estimated to be recognized over a period of 2.2 years as of September 30, 2023. Restricted Stock Units The Company issues RSUs that generally vest over a four-year period with 25% of the RSUs vesting one year from the vesting commencement date, and the remainder vesting quarterly thereafter over the following 36 months. Any unvested shares underlying an RSU will be forfeited upon termination of services. The fair value of an RSU is equal to the fair market value price of the Company’s common stock on the date of grant. A summary of RSU activity during the nine months ended September 30, 2023 is as follows: SHARES WEIGHTED-AVERAGE Unvested shares at December 31, 2022 31,650 $ 11.21 Granted 333,810 8.88 Forfeited (19,151) 9.21 Vested and released (11,587) 11.21 Unvested shares at September 30, 2023 334,722 $ 9.00 As of September 30, 2023, there was $0.9 million of unrecognized stock-based compensation expense related to unvested RSUs. The unrecognized stock-based compensation expense is estimated to be recognized over a period of 3.2 years as of September 30, 2023. Shares of Restricted Common Stock The Company issued shares of restricted common stock to its founders in May 2018, which vested monthly over five years through May 2023. At issuance, these shares also contained certain performance-based vesting criteria which were associated with the milestone events applicable to the formerly outstanding shares of Series A preferred stock, two of which were achieved in 2020. In conjunction with the termination of the Series A preferred stock purchase agreement, the final performance-based vesting criteria was waived, leaving only service-based vesting criteria remaining for the founders’ shares through the end of the requisite service period. As noted above, certain executives who are option holders are able to early exercise stock option awards prior to full satisfaction of the vesting conditions. If and when such exercise occurs, the executive receives shares of restricted common stock. Early exercise shares are included in the table below. A summary of restricted common stock activity during the nine months ended September 30, 2023 is as follows: SHARES WEIGHTED-AVERAGE Unvested shares at December 31, 2022 311,825 $ 3.96 Vesting of restricted common stock (174,894) 2.63 Unvested shares at September 30, 2023 136,931 $ 5.67 As of September 30, 2023, there was $0.8 million of unrecognized stock-based compensation expense related to unvested restricted common stock. The unrecognized stock-based compensation expense is estimated to be recognized over a period of 1.6 years as of September 30, 2023. Stock-based Compensation Expense Total stock-based compensation expense recorded as research and development and general and administrative expenses, respectively, for employees, directors and non-employees during the three and nine months ended September 30, 2023 and 2022 was as follows (in thousands): THREE MONTHS ENDED SEPTEMBER 30, NINE MONTHS ENDED SEPTEMBER 30, 2023 2022 2023 2022 Research and development $ 1,855 $ 3,076 $ 5,278 $ 5,362 General and administrative 1,785 1,399 4,928 3,675 $ 3,640 $ 4,475 $ 10,206 $ 9,037 |

Net Loss Per Share | Net Loss Per Share Basic and diluted loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding (in thousands, except share and per share data): THREE MONTHS ENDED SEPTEMBER 30, NINE MONTHS ENDED SEPTEMBER 30, 2023 2022 2023 2022 Numerator: Net loss $ (13,504) $ (14,745) $ (42,895) $ (36,891) Net loss attributable to common stockholders - basic and diluted $ (13,504) $ (14,745) $ (42,895) $ (36,891) Denominator: Weighted-average common stock outstanding - basic and diluted 43,802,221 38,585,980 43,311,740 38,417,993 Net loss per share attributable to common stockholders - basic and diluted $ (0.31) $ (0.38) $ (0.99) $ (0.96) The Company’s potentially dilutive securities, which include preferred stock, unvested restricted common stock, unvested RSUs and stock options, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average number of shares of common stock outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following from the computation of diluted net loss per share attributable to common stockholders for the three and nine months ended September 30, 2023 and 2022 because including them would have had an anti-dilutive effect: SEPTEMBER 30, 2023 2022 Unvested restricted stock 136,931 399,461 Unvested RSUs 334,722 31,650 Options to purchase common stock 8,713,984 7,287,786 9,185,637 7,718,897 |

Unaudited Interim Financial Information | Unaudited Interim Financial InformationThe accompanying condensed consolidated financial statements and the accompanying notes as of September 30, 2023 and December 31, 2022 and for the three and nine months ended September 30, 2023 and 2022 are unaudited. The condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of September 30, 2023 and the results of its operations for the three and nine months ended September 30, 2023 and 2022 and its cash flows for the nine months ended September 30, 2023 and 2022. |
Use of Estimates | Use of EstimatesThe preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting periods. Estimates and judgments are based on historical information and other market-specific or various relevant assumptions, including in certain circumstances, future projections, that management believes to be reasonable under the circumstances. Actual results could differ materially from estimates. Significant estimates and assumptions are used for, but not limited to, the accruals for research and development expenses. |
Concentration of Credit Risk | Concentration of Credit RiskFinancial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and marketable securities. Periodically, the Company maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and have not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Such deposits have and will continue to exceed federally insured limits. The Company has not experienced any losses on its cash deposits. The Company’s short-term and long-term marketable securities are invested in high grade securities with limited concentration in any one issuer, and as a result, the Company believes represent minimal credit risk. |
Recently Issued and Adopted Accounting Pronouncements | Recently Issued and Adopted Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its condensed consolidated financial statements and disclosures. In June 2016, the FASB issued ASU No. 2016‑13, Financial Instruments—Credit Losses (Topic 326)—Measurement of Credit Losses on Financial Instruments , which has been subsequently amended (“ASU 2016‑13”). This updated accounting guidance significantly changes the impairment model for most financial assets and certain other instruments. ASU 2016-13 will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, which will generally result in earlier recognition of allowances for credit losses on trade receivables, loans and other financial instruments. This update is effective for the Company’s fiscal year beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this new standard on January 1, 2023, and the adoption had no material impact on the Company's consolidated financial statements. |
