SIM0500 is a humanized GPRC5D-BCMA-CD3 tri-specific antibody independently developed through Simcere Zaiming’s T-cell engager polyspecific antibody technology platform. By combining a low affinity/high target activating CD3 antibody, along with 2 tumor-related antibodies(GPRC5D, BCMA), this novel T cell-activating molecule specifically targets MM tumor cells and has an enhanced tumor suppression activity through the synergy of multiple target effects.


Data from preclinical studies has demonstrated a favorable tumor-killing effect and good tolerance of SIM0500 even at low doses. In animal models, no tumor recurrence is observed after drug discontinuation. It is potentially a best-in-class candidate that may provide new therapeutic choices to overcome the drug resistance caused by existing treatments of MM.
