Liquidity and Going Concern |
Liquidity and Going Concern | 2. Liquidity and Going Concern The Company has incurred significant operating losses since inception and has primarily relied on equity, debt, grant, and award financing to fund its operations. As of September 30, 2025, the Company had an accumulated deficit of $377.2 million. The Company expects to continue to incur substantial losses, and its transition to profitability will depend on the successful development, approval and commercialization of product candidates and on the achievement of sufficient revenues to support its cost structure. The Company may never achieve profitability, and unless and until then, the Company will need to continue to raise additional capital. The existing cash and cash equivalents of $14.8 million as of September 30, 2025 will not be sufficient to fund its operations for the next 12 months from the date of these condensed consolidated financial statements. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern. The Company has prepared its condensed consolidated financial statements on a going concern basis, which assumes that the Company will realize its assets and satisfy its liabilities in the normal course of business. The accompanying condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern. Recent Financing: August 2025 Credit Agreement On August 11, 2025, the Company entered into a credit and security agreement (the “August 2025 Credit Agreement”) for a loan in the aggregate amount of $15.0 million (the “August 2025 Loan”) with Innoviva Strategic Opportunities LLC, a wholly owned subsidiary of Innoviva, Inc. (NASDAQ: INVA), the Company’s principal stockholder and a related party (collectively, “Innoviva”). The August 2025 Loan bears interest at an annual rate of 14.0% and matures on January 11, 2029. Principal and accrued interest are payable at maturity. Repayment of the August 2025 Loan is guaranteed by the Company’s domestic subsidiaries, and the loan is secured by substantially all of the assets of the Company and the subsidiary guarantors. March 2025 Credit Agreement On March 12, 2025, the Company entered into a credit and security agreement (the “March 2025 Credit Agreement”) for a loan in an aggregate amount of $10.0 million (the “March 2025 Loan”) with Innoviva. The March 2025 Loan bears interest at an annual rate of 14.0% and matures on March 12, 2026. Principal and accrued interest are payable at maturity. Repayment of the March 2025 Loan is guaranteed by the Company’s domestic subsidiaries, and the loan is secured by substantially all of the assets of the Company and the subsidiary guarantors. ​ Concurrently with the execution of the March 2025 Credit Agreement, the Company entered into amendments to (i) its existing convertible loan (the “Convertible Loan”) and secured credit and security agreement, dated January 10, 2023, with Innoviva (the “Convertible Credit Agreement”), (ii) its existing secured term loan facility (the “2023 Loan”) and credit and security agreement, dated July 10, 2023, with Innoviva (the “2023 Credit Agreement”) and (iii) its existing secured term loan facility (the “2024 Loan”) and credit and security agreement, dated March 4, 2024, with Innoviva (the “2024 Credit Agreement”), which, among other things, extended the maturity date of each loan to March 12, 2026. ​ 2024 Credit Agreement On March 4, 2024, the Company entered into the 2024 Credit Agreement for the 2024 Loan in an aggregate amount of $35.0 million. The 2024 Loan bears interest at an annual rate of 14.0% and matures on March 12, 2026. Principal and accrued interest are payable at maturity. Repayment of the 2024 Loan is guaranteed by the Company’s domestic subsidiaries, and the loan is secured by substantially all of the assets of the Company and the subsidiary guarantors. Concurrently with the execution of the 2024 Credit Agreement, the Company amended certain provisions of the Convertible Loan and Convertible Credit Agreement and the 2023 Loan and 2023 Credit Agreement to, among other things, conform certain terms relating to permitted indebtedness and permitted liens. ​ The Company plans to raise additional capital through equity offerings, debt financings, or other capital sources, including potential collaborations, licenses and other similar arrangements. While the Company believes this plan to raise additional funds will alleviate the conditions that raise substantial doubt about the Company’s ability to continue as a going concern, these plans are not entirely within its control and cannot be assessed as being probable of occurring. The Company’s ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, financial markets in the United States and worldwide. The Company may not be able to secure additional financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity securities to raise additional funds, its existing stockholders may experience dilution, and the new equity securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products on terms that are not favorable to the Company. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or other operations. If any of these events occur, the Company’s ability to achieve the development and commercialization goals would be adversely affected.
