Simcere Zaiming and AbbVie Announce Partnership to Develop a Novel Trispecific Antibody Candidate in Multiple Myeloma

SHANGHAI and NORTH CHICAGO, Ill., Jan. 13, 2025 /PRNewswire/ -- Simcere Zaiming, a subsidiary of Simcere Pharmaceutical Group Ltd (HKEX: 2096) and AbbVie Inc. (NYSE: ABBV) today announced an option to license agreement to develop SIM0500, an investigational new drug candidate. SIM0500 is currently in Phase 1 clinical trials in patients with relapsed or refractory multiple myeloma (MM), in both China and the U.S.
