Material Changes vs. Prior Period
- Expense Reduction: Total operating expenses decreased by $9.4 million (32%) compared to Q1 2024. This was driven by a $6.4 million decrease in R&D and a $3.1 million decrease in G&A.
- R&D Drivers: The reduction in R&D expenses was primarily due to the suspension of the losmapimod program (following a failed Phase 3 trial in September 2024) and a $1.0 million reimbursement from Sanofi for global development cost sharing. This was partially offset by increased costs for the pociredir Phase 1b trial.
- Headcount Reduction: Following a workforce reduction in September 2024 (from 80 to 51 employees), employee compensation costs decreased significantly in both R&D and G&A.
- Liquidity: Cash and marketable securities decreased by approximately $14.4 million, primarily due to net cash used in operating activities and net purchases of marketable securities.
Guidance, Outlook, and Risks
- Clinical Outlook: The company expects to provide clinical data from the 12 mg dose cohort of the pociredir Phase 1b trial in the early third quarter of 2025 and data from the 20 mg dose cohort by the end of 2025. An Investigational New Drug (IND) application for Diamond-Blackfan Anemia (DBA) is planned for the fourth quarter of 2025.
- Liquidity Runway: Management believes current cash, cash equivalents, and marketable securities ($226.6 million) are sufficient to fund operations and capital expenditures into at least 2027.
- Collaboration Terminations:
- Sanofi: The collaboration for losmapimod was terminated for convenience, effective April 17, 2025. No further milestone payments or royalties are expected.
- MyoKardia: The collaboration agreement was terminated for convenience, effective June 26, 2025. No further payments are expected.
- Risks: Key risks include the uncertainty of clinical trial outcomes for pociredir, the need for substantial additional funding in the future, reliance on third-party manufacturers (CMOs), and potential regulatory delays. The company also faces risks related to the recent change in U.S. presidential administration and potential shifts in FDA policy.
Investor Verification Checklist
- Verify the timeline for the release of pociredir Phase 1b data (Q3 2025) and the initiation of the 20 mg cohort.
- Confirm the status of the Sanofi and MyoKardia termination agreements and ensure no contingent liabilities remain.
- Monitor the company's cash burn rate against the stated 2027 liquidity runway, particularly as pociredir trials advance.
- Review the progress of the DBA program and the planned Q4 2025 IND filing.
- Assess the impact of the September 2024 workforce reduction on the company's ability to execute its development plans.
