As of April 30, 2025, 10 patients treated at this level achieved a 50% overall response rate (ORR). Notably, one patient with prior progression on two T-cell engager therapies achieved a minimal residual disease negative complete response. Eight patients (80%) at this dose level had prior CAR-T or T-cell engager therapy.
- Multiple Myeloma (75 µg QD Dose): A total of 20 patients have been treated. As of April 30, 2025, this dose level achieved a 40% ORR.
- Safety Profile: Cemsidomide remains well-tolerated with manageable neutropenia.
- Non-Hodgkin's Lymphoma: Phase 1 dose escalation is ongoing at the 87.5 µg QD dose level; the maximum tolerated dose has not yet been reached.
Guidance, Outlook, and Risks
Outlook: The Company expects to receive regulatory feedback on registrational development for cemsidomide by mid-year 2025. This feedback is intended to support the initiation of the next phase of development in early 2026.
Risks and Contingencies: The filing includes standard forward-looking statement disclaimers. Key risks include uncertainties in clinical study timing and conduct, the potential for product candidates to fail development or commercialization, and the risk that sufficient capital to fund future operations may not be available on acceptable terms.
