• The FDA has approved UPLIZNA (inebilizumab-cdon) as the first and only treatment for adults with IgG4-related disease, a chronic immune-mediated inflammatory condition that can cause permanent organ damage.
• In the pivotal MITIGATE trial, UPLIZNA demonstrated an 87% reduction in flare risk compared to placebo and allowed nearly 60% of patients to achieve corticosteroid-free, flare-free complete remission.
• The approval marks Amgen's expanding leadership in CD19-directed B-cell depletion therapies across multiple autoimmune diseases, including NMOSD, IgG4-RD, and potentially generalized myasthenia gravis.
