Innovent Biologics IncDosed first patient in pivotal Phase 3 trial of novel tri-specific antibody IBI3003 for multiple myeloma, with promising Phase 1/2 data and FDA Fast Track Designation.

Innovent Biologics has dosed the first patient in the Chinese pivotal Phase 3 clinical trial of its self-developed tri-specific antibody IBI3003 for relapsed or refractory multiple myeloma. The trial, called TriadicMM-1, is a multicenter, randomized, controlled, open-label study evaluating IBI3003 against investigator's choice of either PVd or DPd, with progression-free survival as the primary endpoint. IBI3003 targets GPRC5D, BCMA, and CD3, and is China's first self-developed tri-specific antibody to enter a pivotal registrational Phase 3 trial. Earlier Phase 1/2 data presented at the 2025 ASH meeting showed an 83.3% overall response rate among patients treated at doses of at least 120 μg/kg, with all cytokine release syndrome cases being Grade 1-2. The therapy has also received Fast Track Designation from the U.S. FDA for patients who have received four or more prior lines of therapy.
