Hansoh Pharmaceutical Group Co., Ltd. announced on September 1, 2025, that their innovative drug XINYUE (Inebilizumab Injection) has received drug registration approval from China's National Medical Products Administration (NMPA) for a second indication. The approval allows the drug to be used for treating immunoglobulin G4-related disease (IgG4-RD) in adult patients. This decision follows the inclusion of the indication in the NMPA's Priority Review and Approval Procedure earlier this year. The approval is backed by positive results from the MITIGATE trial, which demonstrated inebilizumab's effectiveness in reducing disease flares and maintaining a strong safety profile. Hansoh Pharma's collaborator, Amgen, had previously received approval from the U.S. FDA for the same indication in April 2025.
