Accounting Policies [Abstract] |
Segment Reporting | Segment Reporting The company operates in one business segment in the United States, which includes all activities related to the development of novel therapies across a range of cancers. The Company's chief operating decision-maker is its chief executive officer. The chief operating decision-maker allocates resources based on available cash, cash equivalents and short-term investments. The primary measure of performance reviewed by the chief operating decision-maker is net loss which is compared to the annual budget and quarterly forecasts. All financial information required for segment reporting that is provided to the chief operating decision-maker is contained within the financial statements and notes to financial statements, with the exception of the disaggregated amounts contained in the table below:

Use of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimate involves accrued clinical trial expenses.
Accrued Clinical Trial Expenses | Accrued Clinical Trial Expenses The Company expenses research and development expenditures as incurred, which include costs related to clinical trial activities. The Company accrues costs for clinical trial activities based upon estimates of the services received and related expenses incurred that have yet to be invoiced by the Clinical Research Organizations ("CROs"), investigators, professional service providers, and other vendors providing clinical trial services (collectively, the “service providers”). The Company considers several elements including the key terms of the clinical trial agreements, budgets, contract amendments, and the progress of clinical trials toward completion (which includes consideration of patient enrollment) in estimating the clinical trial accrual. As of December 31, 2025 and 2024, the Company’s clinical trial accrual balance of $3.8 million and $4.4 million, respectively, is included in accrued liabilities. The Company’s related clinical trial expenses are included in research and development expense.
Cash and Cash Equivalents | Cash and Cash Equivalents 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 and cash equivalents consist of cash in readily available checking and money market accounts. Cash and Cash Equivalents The Company maintains deposit accounts at financial institutions that are in excess of federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash due to the financial position of the depository institution in which those deposits are held. The Company limits its exposure to credit loss by generally placing its cash in high credit quality financial institutions and investment in non FDIC insured money market funds denominated and payable in U.S. dollars.
Investment Securities | Investment Securities Investment transactions are recorded on the trade date, and purchases of investments that are settled after the balance sheet date are included in accrued liabilities. All investments have been classified as “available-for-sale” and are carried at fair value as determined based upon quoted market prices or pricing models for similar securities at period end. Investments with contractual maturities less than 12 months at the balance sheet date are considered short-term investments. Investments with contractual maturities beyond one year are also classified as short-term due to the Company’s ability to liquidate the investment for use in operations within the next 12 months. Realized gains and losses on investment securities are included in earnings and are derived using the specific identification method for determining the cost of securities sold. The Company has not realized any significant gains or losses on sales of available-for-sale investment securities during any of the periods presented. As all the Company’s investment holdings are in the form of debt securities or certificates of deposit, unrealized gains and losses that are determined to be temporary in nature are reported as a component of accumulated other comprehensive loss. A decline in the fair value of any security below cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for the security. Interest income is recognized when earned and is included in investment income, as are the amortization of purchase premiums and accretion of purchase discounts on investment securities. Short-term Investments The Company follows an investment policy which requires short-term investments to be diversified across different types of instruments and issuers. The investment policy also requires investments to be in high quality instruments. The diversification and credit quality requirements of the Company's investment policy limits its exposure to credit loss.
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents and short-term investments as follows:
Revenues | Revenues The Company recognizes revenue when control of its products and services are transferred to its customers in an amount that reflects the consideration it expects to receive from its customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. The Company considers a performance obligation satisfied once it has transferred control of goods or service to the customer, meaning the customer has the ability to use and obtain the benefit of goods or service. The Company recognizes revenue for satisfied performance obligations only when it determines there are no uncertainties regarding payment terms or transfer of control. For sales-based royalties, 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). Royalty and License Revenues The Company licenses and sublicenses its patent rights to healthcare companies, medical laboratories and biotechnology partners. These patents are from the Company's legacy portfolio and unrelated to onvansertib. Agreements may involve multiple elements such as license fees, minimum royalties, usage-based royalties and milestone payments. Revenue is recognized when the criteria described above have been met as well as the following: • Up-front nonrefundable license fees pursuant to agreements under which the Company has no continuing performance obligations are recognized as revenues on the effective date of the agreement and when collection is probable. • Minimum royalties are recognized as earned, and royalties are earned based on the licensee’s use. The Company estimates and records licensee’s sales based on historical usage rate and collectability. • For sales-based royalties, 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). Payment terms and conditions vary by contracts, although terms generally include a requirement of payment within 30 to 45 days after invoice. Royalties are generally due quarterly or annually.
Stock-Based Compensation | Stock-Based Compensation Stock-based compensation expense is measured at the grant date based on the estimated fair value of the award and is recognized straight-line over the requisite service period of the individual grants, which typically equals the vesting period. The Company estimates forfeitures based on its historical experience.
Fair Value of Financial Instruments | Fair Value of Financial Instruments Financial instruments consist of cash equivalents, investments, accounts receivable, and accounts payable. The Company applies ASC 820 for financial assets and liabilities that are required to be measured at fair value and non-financial assets and liabilities that are not required to be measured at fair value on a recurring basis. These financial instruments are stated at their respective historical carrying amounts, which approximate fair value due to their short-term nature as they reflect current market interest rates. The authoritative guidance establishes a fair value hierarchy that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities. In general, the authoritative guidance requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the measurement of its fair value. The three levels of input defined by the authoritative guidance are as follows: • Level 1 — Quoted prices for identical instruments in active markets. • Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations where inputs are observable or where significant value drivers are observable. • Level 3 — Instruments where significant value drivers are unobservable to third parties.
Long-Lived Assets | Long-Lived Assets Long-lived assets consist of property, equipment and lease right-of-use assets. The Company records property and equipment at cost. Depreciation on property and equipment is calculated using the straight-line method over the estimated useful life of the asset. Depreciation of leasehold improvements is computed based on the shorter of the life of the asset or the term of the lease. The estimated useful lives of the major classes of property and equipment are as follows:
| Estimated Useful Lives
Furniture and office equipment | 3 to 5 years
Leasehold improvements | 4 to 6 years
Laboratory equipment | 5 years
Impairment Losses on Long-Lived Assets | Impairment losses on long-lived assets used in operations are recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets carrying amount. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets.
Leases | Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease Right-of-Use (“ROU”) assets, current operating lease liabilities and non-current operating lease liabilities in the Company’s balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. None of the Company’s operating leases provide an implicit rate, therefore the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate is the rate of interest that the Company would expect to pay to borrow on a collateralized and fully amortizing basis over a similar term an amount equal to the lease payments in a similar economic environment. The operating lease ROU asset also includes any lease payments made less lease incentives received. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. Our facilities lease agreement contains lease and non-lease components, such as common area maintenance. The Company elected to account for these lease and non-lease components of this agreement as a single lease component. Leases with an initial term of 12 months or less are not recorded on the Company's balance sheets. These short-term leases are expensed on a straight-line basis over the lease term.
Income Taxes | Income Taxes Income taxes are determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. Deferred taxes result from differences between the financial statement and tax bases of assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The Company’s policy is to recognize the interest expense and/or penalties related to income tax matters as a component of income tax expense.
Contingencies | Contingencies In the normal course of business, the Company is subject to loss contingencies, such as legal proceedings and claims arising out of its business, that cover a wide range of matters, including, among others, government investigations, stockholder lawsuits, product and environmental liability, and tax matters. In accordance with FASB ASC Topic 450, Contingencies, the Company records such loss contingencies when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company, in accordance with this guidance, does not recognize gain contingencies until realized.
Research and Development | Research and Development Research and development expenses include expenditures in connection with an in-house research and development laboratory, salaries and staff costs, clinical trials, purchased in-process research and development and regulatory and scientific consulting fees, as well as contract research and insurance. Also, patent filing and patent maintenance expenses are considered legal in nature and therefore classified as general and administrative expense, if any. Non-refundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. As the related goods are delivered or the services are performed, or when the goods or services are no longer expected to be provided, the deferred amounts are recognized as an expense. Upfront and milestone payments to acquire contractual rights to licensed technology are expensed when incurred if there is uncertainty in the Company receiving future economic benefit from the acquired contractual rights. Certain contractual rights may require the Company to make additional milestone payments based on development and commercial milestones, and royalties based on sales volume. See Note 9 - Commitments and Contingencies, for further details. These potential development milestones include: (a) dosing of the first subject in the first Phase III Clinical Trial for the first Product, a registration enabling Phase II Clinical Trial, or after completion of a Phase II Clinical Trial that is used as the basis for an NDA submission; and (b) upon filing of the first NDA or equivalent for the first product candidate.
Net Loss Per Share | Net Loss Per Share Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding during the period. The accretion of Series A Convertible Preferred Stock dividends and deemed dividends recognized in connection with certain preferred share issuances are included in net loss attributable to common stockholders in the computation of basic and diluted earnings per share. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as inclusion of the potentially dilutive securities would be antidilutive. Shares used in calculating diluted net loss per common share exclude as anti-dilutive the following share equivalents:
|  | December 31, |

Options to purchase Common Stock |  |  | 10,757,293 |  |  |  | 8,334,765 |

Series A Convertible Preferred Stock |  |  | 877 |  |  |  | 877 |
|  |  | 10,758,602 |  |  |  | 11,142,995 |
Recently Adopted Accounting Pronouncement | Recently Adopted Accounting Pronouncement In August 2020, the Financial Accounting Standards Board ("the FASB") issued ASU No. 2020-06 ("ASU 2020-06"), Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”). ASU 2020-06 eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. This update was effective for the Company on January 1, 2024. The amendment is to be adopted through either a fully retrospective or modified retrospective method of transition. The Company adopted this standard as of January 1, 2024 using the modified-retrospective method. As a result of the adoption, the Company reversed the accretion of preferred stock dividends originally recorded in 2005 related to the Series A Convertible Preferred Stock of $793,000. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for public entities with annual periods beginning after December 15, 2024 and for private businesses for annual periods beginning after December 15, 2025, with early adoption permitted. The Company has adopted this standard as of January 1, 2025 using the retrospective method for the comparative period with additional disclosure contained in Note 8 Income Taxes. Recent Accounting Pronouncement Not Yet Adopted In November 2024, the FASB issued ASU 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, to enhance the transparency of certain expense disclosures. The update requires disclosure of specific expense categories in the notes to the financial statements at interim and annual reporting periods. The update requires disaggregated information about certain prescribed expense categories underlying any relevant income statement expense caption. The amendments in this update are effective for public entities for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. The amendments may be adopted either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its financial statement disclosures.
