Mabwell's 9MW5211 Receives IND Clearance from NMPA for Inflammatory Bowel Disease

SHANGHAI, June 4, 2026 /PRNewswire/ -- Mabwell (688062.SH, 02493.HK), an innovation-driven biopharmaceutical company with a fully integrated industry chain, announced that its independently developed innovative antibody drug 9MW5211 has received approval from the National Medical Products Administration (NMPA) to conduct clinical trials for inflammatory bowel disease (IBD). 9MW5211 is the first candidate drug for its target to enter clinical stage globally.

9MW5211 is a highly specific, depleting, and innovative antibody independently developed by Mabwell, designed to precisely intervene in the key pathological mechanisms mediated by abnormal immune cells in autoimmune diseases. The abnormal activation and tissue infiltration of immune cells act as the core driving factors in the occurrence and development of various autoimmune diseases. The target molecule of 9MW5211 is specifically expressed on the surface of pathogenic immune cells and serves as a vital biological marker of their abnormal activation. By selectively recognizing and depleting this population of pathogenic cells, 9MW5211 can effectively block the immune cascade, thereby delaying disease progression and ameliorating clinical symptoms.
