C4 Therapeutics (NASDAQ:CCCC) has entered into a clinical trial collaboration and supply agreement with Pfizer to evaluate the combination of cemsidomide and elranatamab for treating relapsed/refractory multiple myeloma. The upcoming Phase 1b trial, set to begin in Q2 2026, will assess the safety and optimal dosing of cemsidomide (an IKZF1/3 degrader) with dexamethasone and elranatamab (Pfizer's BCMAxCD3 bispecific antibody) as a second-line or later therapy.
Under the agreement, Pfizer will provide elranatamab at no cost, while C4T will sponsor and conduct the trial. Early Phase 1 data shows cemsidomide demonstrates robust T-cell activation and cytokine expression, suggesting potential synergistic effects when combined with elranatamab to enhance anti-myeloma immune response.
C4 Therapeutics (NASDAQ:CCCC) presented promising Phase 1 clinical trial data for cemsidomide, an oral IKZF1/3 degrader, in combination with dexamethasone for treating relapsed/refractory multiple myeloma. The trial showed 50% overall response rate (ORR) at the highest dose level (100 µg) and 40% ORR at the 75 µg dose level in heavily pre-treated patients.
Key highlights include a median duration of response of 9.3 months across all dose levels, with median duration not yet reached at the two highest doses. The drug demonstrated a favorable safety profile with no treatment discontinuations and minimal dose reductions. The study involved 72 patients who had received a median of seven prior therapies, with 75% having previous BCMA-targeted therapy exposure.
C4T plans to pursue two distinct opportunities for accelerated approval through a Phase 2 trial in Q1 2026 for fourth-line therapy and a Phase 1b trial in Q2 2026 to evaluate combination with BCMA BiTE in second-line therapy.
