First Patient Dosed in Ph 1b Trial of Cemsidomide in Combination with Elranatamab (ELREXFIO) for Relapsed/Refractory Multiple Myeloma

“Data from our Phase 1 trial support cemsidomide as a potential best-in-class, next-generation IKZF1/3 degrader and the initiation of this Phase 1b trial, along with our late-line Phase 2 MOMENTUM trial, enable an efficient path toward bringing cemsidomide to growing myeloma patient populations across multiple lines of therapy,” said Len Reyno, M.D., chief medical officer of C4 Therapeutics. “Bispecific T-cell engagers have quickly become a critical treatment pillar in multiple myeloma while IKZF1/3 degraders remain foundational therapies across multiple lines and combination regimens in multiple myeloma. In this combination with elranatamab, we see an opportunity to leverage cemsidomide’s potent direct anti-myeloma effect and its ability to enhance the immune environment which has the potential to deliver a deeper and more durable therapeutic response for patients, including those in earlier lines of therapy.”
