Basis of Presentation - Unaudited Interim Financial Information

Basis of Presentation - Unaudited Interim Financial Information - The accompanying unaudited interim condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) with respect to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements furnished reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Principles of Consolidation

Principles of Consolidation - The basis of consolidation is unchanged from the disclosure in the Company’s Notes to the Consolidated Financial Statements section in its Annual Report on Form 10-K for the year ended December 31, 2024. The unaudited condensed consolidated financial statements include the Company’s accounts and those of the Company’s wholly owned subsidiaries.

Use of Estimates

Use of Estimates - The preparation of these unaudited interim 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 at the date of the unaudited interim condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Segment Information

Segment Information - The Company operates as a single operating and reportable segment for the purposes of assessing performance and allocating resources. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews total assets in the consolidated balance sheets and net loss and its components in the consolidated statements of operations; research and development expenses, general and administrative expenses, and interest income, for the purposes of making operating decisions, assessing financial performance, and allocating resources. All assets are in the United States.

Cash, Cash Equivalents and Restricted Cash

Cash, Cash Equivalents and Restricted Cash - The Company considers all highly liquid accounts with original maturities of three months or less to be cash equivalents. The Company holds most of its cash equivalents in a money market account comprised of US Treasury notes. Balances held by the Company are typically in excess of Federal Deposit Insurance Corporation insured limits.

The following is a summary of cash, cash equivalents and restricted cash at September 30, 2025 and December 31, 2024:

(in thousands)   September 30,
2025
    December 31,
2024
 
Cash and cash equivalents   $ 53,391     $ 72,904  
Restricted cash – long-term     332       324  
Cash, cash equivalents and restricted cash   $ 53,723     $ 73,228  

Restricted cash relates to a certificate of deposit held as collateral for a letter of credit issued in connection with the Company’s lease of corporate office space.

Leases

Leases – The Company has an operating lease for corporate office space and a finance lease for office equipment located at the corporate office space. Leases with an initial term of 12 months or less are not recorded on the balance sheet; lease expense for these leases is recognized on a straight-line basis over the lease term.

Fair Value Measurement

 Fair Value Measurement - Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. A fair value hierarchy has been established for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

Revenue Recognition

Revenue Recognition - The Company recognizes revenue in accordance with Accounting Standards Codification (ASC) Topic 606, Revenue From Contracts With Customers (“ASC 606”). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue as the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the goods or services it transfers to the customer.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses whether the promised goods or services promised within each contract are distinct and, therefore, represent a separate performance obligation. Goods and services that are determined not to be distinct are combined with other promised goods and services until a distinct bundle is identified. In determining whether goods or services are distinct, the Company evaluates certain criteria, including whether (i) the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (capable of being distinct) and (ii) the good or service is separately identifiable from other goods or services in the contract (distinct in the context of the contract).

The Company then determines the transaction price, which is the amount of consideration it expects to be entitled from a customer in exchange for the promised goods or services for each performance obligation and recognizes the associated revenue as each performance obligation is satisfied. The Company’s estimate of the transaction price for each contract includes all variable consideration to which it expects to be entitled. Variable consideration includes payments in the form of collaboration milestone payments. If an arrangement includes collaboration milestone payments, the Company evaluates whether the milestones are considered probable of being reached 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.

ASC 606 requires the Company to allocate the arrangement consideration on a relative standalone selling price basis for each performance obligation after determining the transaction price of the contract and identifying the performance obligations to which that amount should be allocated. The relative standalone selling price is defined in the revenue standard as the price at which an entity would sell a promised good or service separately to a customer. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation as each performance obligation is satisfied, either at a point in time or over time, and if over time, recognition is based on the use of an output or input method.

Collaborative Arrangements

Collaborative Arrangements - The Company follows the accounting guidance for collaboration agreements with third parties, which requires that certain transactions between the Company and collaborators be recorded in its consolidated statements of operations on either a gross basis or net basis, depending on the characteristics of the collaborative relationship, and requires enhanced disclosure of collaborative relationships. The Company evaluates its collaboration agreements for proper classification in its consolidated statements of operations based on the nature of the underlying activity. When the Company has concluded that it has a customer relationship with one of its collaborators, the Company follows the guidance of ASC 606. There was no revenue from collaborative arrangements for the nine months ended September 30, 2025 and September 30, 2024, respectively.

Grant Revenue

Grant Revenue The Company has a grant from a government-sponsored entity for research and development related activities that provides for payments for reimbursed costs, which included overhead and general and administrative costs as well as an administrative fee. The Company recognizes revenue from grants as it performed services under this arrangement. Associated expenses are recognized when incurred as research and development expense. Revenue and related expenses are presented gross in the consolidated statements of operations. Grant revenue for the three and nine months ended September 30, 2025 was $0.1 million. There was no grant revenue recognized for the three and nine months ended September 30, 2024.

License Revenue

 License Revenue The Company entered into a product licensing agreement whereby the Company allowed a third party to commercialize a certain product in specified territories using the Company’s trademarks. The terms of this arrangement includes payment to the Company for a combination of one or more of the following: upfront license fees; development, regulatory and sales-based milestone payments; and royalties on net sales of licensed products. The Company uses its judgment to determine whether milestones or other variable consideration should be included in the transaction price.

Upfront license fees: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company will recognize revenue from upfront license fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company determines whether the combined performance obligation is satisfied over time or at a point in time.

Development, regulatory or commercial milestone payments: At the inception of each arrangement that includes payments based on the achievement of certain development, regulatory and sales-based or commercial events, 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 Company’s or the licensee’s control, such as regulatory approvals, are not considered probable of being achieved until regulatory approval is received. At the end of each subsequent reporting period, the Company will re-evaluate the probability of achieving such development and regulatory milestones and any related constraint, and if necessary, adjust the Company’s estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis and recorded as part of license revenue during the period of adjustment.

Sales-based milestone payments and royalties: For arrangements that include sales-based royalties, including milestone payments based on the volume of sales, the Company will determine whether the license is deemed to be the predominant item to which the royalties or sales-based milestones relate and if such is the case, the Company will recognize 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).

Upfront payments and fees may require deferral of revenue recognition to a future period until the Company performs its obligations under these arrangements or when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or when the uncertainty associated with any variable consideration is subsequently resolved. Amounts payable to the Company are recorded as accounts receivable when the Company’s right to consideration is unconditional. There was no license revenue for the three and nine months ended September 30, 2025 and September 30, 2024.

Research and Development Costs

Research and Development Costs - Research and development costs are expensed as incurred. These costs include the costs of manufacturing drug product, the costs of clinical trials, costs of employees and associated overhead, and depreciation and amortization costs related to facilities and equipment. Research and development reimbursements are recorded by the Company as a reduction of research and development costs.

Share-Based Payments

Share-Based Payments - The Company estimates the fair value of each stock option award at the grant date by using the Black-Scholes option pricing model. The fair value determined represents the cost for the award and is recognized over the vesting period during which an employee is required to provide service in exchange for the award. The Company accounts for forfeitures of stock options as they occur.

Net Loss Per Common Share

Net Loss Per Common Share - Basic loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the reporting period. For periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive. For the three and nine months ended September 30, 2025 and 2024, the Company’s potentially dilutive shares, which include outstanding common stock options, restricted stock units, vested unissued shares of common stock and warrants, have not been included in the computation of diluted net loss per share as the result would have been anti-dilutive.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board, (the “FASB”), issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide improvements primarily related to the rate reconciliation and income taxes paid information included in income tax disclosures. The Company is required to disclose additional information regarding reconciling items equal to or greater than five percent of the amount computed by multiplying pretax income (loss) by the applicable statutory tax rate. Similarly, the Company is required to disclose income taxes paid (net of refunds received) equal to or greater than five percent of total income taxes paid (net of refunds received). The amendments in ASU 2023-09 are effective January 1, 2025. The Company adopted this standard effective January 1, 2025 and will report on it in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The Company will update all required disclosures pursuant to ASU 2023-09 at that time. 

In July 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others expected to be implemented through 2027. The Company has evaluated the impact of the OBBBA and determined that it does not have a material impact on the Company’s consolidated financial position and results of operations.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract, which excludes from derivative accounting non-exchange-traded contracts with underlying terms that are based on operations or activities specific to one of the parties to the contract. However, this scope exception does not apply to (1) variables based on a market rate, market price, or market index, (2) variables based on the price or performance of a financial asset or financial liability of one of the parties to the contract, (3) contracts (or features) involving the issuer’s own equity that are evaluated under the guidance in Subtopic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity, and (4) call options and put options on debt instruments. The Company can apply the amendments in AUS 2025-07 either (1) prospectively to new contracts entered into on or after the date of adoption or (2) on a modified retrospective basis through a cumulative-effect adjustment to the opening balance of retained earnings as of the beginning of the annual reporting period of adoption for contracts existing as of the beginning of the annual reporting period of adoption. The amendments in ASU 2025-07 are effective January 1, 2027, for annual for annual reporting periods, including interim periods within annual reporting periods. Early adoption is permitted. The Company is evaluating the impact of ASU 2025-07 on its financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for software costs that are accounted for under Subtopic 350-40. The amendments in ASU 2025-06 remove all references to prescriptive and sequential software development stages (referred to as “project stages”) throughout Subtopic 350-40. Therefore, an entity is required to start capitalizing software costs when both of the following occur: (a) the Company has authorized and committed to funding the software project and (b) it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the “probable-to-complete recognition threshold”). In evaluating the probable-to-complete recognition threshold, the Company is required to consider whether there is significant uncertainty associated with the development activities of the software, such as determining whether (a) the software being developed has technological innovations or novel, unique, or unproven functions or features, and the uncertainty related to those technological innovations, functions, or features, if identified, has not been resolved through coding and testing and (b) the Company has determined what it needs the software to do (for example, functions or features), including whether the entity has identified or continues to substantially revise the software’s significant performance requirements. ASU 2025-06 specifies that disclosures in Subtopic 360- 10, Property, Plant, and Equipment—Overall, are required for all capitalized internal-use software costs, regardless of how those costs are presented in the financial statements and removes the requirement to disclose internal-use software information pursuant to paragraphs 350-30-50-1 through 50-3. ASU 2025-06 supersedes the website development costs guidance and incorporates the recognition requirements for website-specific development costs from Subtopic 350-50, Website Development Costs, into Subtopic 350-40. The amendments in ASU 2025-06 permit an entity to apply the new guidance using either (i) a prospective transition approach, (ii) a modified transition approach that is based on the status of the project and whether software costs were capitalized before the date of adoption, or (iii) a retrospective transition approach. The amendments in ASU 2025-06 are effective January 1, 2028 for annual reporting periods, including interim periods within annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company is evaluating the impact of ASU 2025-06 on its financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which permits a practical expedient whereby, when assessing credit losses on current accounts receivable and current contract assets, the Company would assume that current conditions as of the balance sheet date do not change for the remaining life of the asset and would not require the Company to consider adjustments to forecasts to also include anticipated changes in the future to the underlying conditions as of the balance sheet date when measuring the credit losses for current accounts receivable and current contract assets. The amendments in ASU 2025-05 are effective January 1, 2026 for annual reporting periods, including interim periods within annual reporting periods and is required to be applied on a perspective basis. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. The impact of ASU 2025-04 is not expected to be material to the financial statements.

In May 2025, FASB issued ASU 2025-04, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer, which revises the Master Glossary definition of the term “performance condition” for share-based consideration payable to a customer to include conditions, such as vesting conditions, that are based on the volume or monetary amount of a customer’s purchases or potential purchases of goods or services from the grantor, including over a specified period of time. The revised definition also incorporates performance targets based on purchases made by other parties that purchase the grantor’s goods or services from the grantor’s customers. The revised definition of the term performance condition cannot be applied by analogy to awards granted to employees and non-employees in exchange for goods or services to be used or consumed in the grantor’s own operations. ASU 2025-04 eliminates the policy election permitting a grantor to account for forfeitures as they occur for share-based awards granted to a customer. Separate policy elections for forfeitures remain available for share-based payment awards with service conditions granted to employees and non-employees in exchange for goods or services to be used or consumed in the grantor’s own operations. ASU 2025-04 further clarifies that a grantor should not apply the guidance in Topic 606 on constraining estimates of variable consideration to share-based consideration payable to a customer. ASU 2025-04 permits a grantor to apply the new guidance on either a modified retrospective or a retrospective basis. The amendments in ASU 2025-04 are effective January 1, 2027 for annual reporting periods, including interim periods within annual reporting periods. The Company is evaluating the impact of ASU 2025-04 on its financial statements.

In November 2024, FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40), to improve the disaggregation of expenses within the consolidated statement of operations. The amendments in ASU 2024-03 require disclosures in the notes to the consolidated financial statements and specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity disclose (a) employee compensation, (b) depreciation, and (c) intangible asset amortization included in each relevant expense caption; include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements; and disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. The amendments in ASU 2024-03 are effective January 1, 2027 and effective for interim periods beginning January 1, 2028, either on a prospective or retrospective basis. The Company is evaluating the impact of ASU 2024-03 on its financial statements.
