Amgen’s Uplizna OK’d for Immunoglobulin G4 Disease
FDA has approved an Amgen supplemental BLA for Uplizna (inebilizumab-cdon) for treating adults living with immunoglobulin G4-related disease (IgG4-RD), which is described as a chronic and debilitating immune-mediated inflammatory condition that can affect and damage multiple organs. The approval is based on data from the MITIGATE trial that showed Uplizna’s potential to decrease disease activity by reducing flares in patients, according to the company. Uplizna was originally approved in 2020 for treating adult patients with AQP4-IgG+ neuromyelitis optica spectrum disorder.
Amgen says data from MITIGATE trial showed an 87% reduction in the risk of IgG4-RD flares in Uplina-treated patients compared to placebo. It also showed a reduction in the annualized flare rate for patients treated with the therapy. Additionally, 57.4% of Uplizna patients achieved flare-free, treatment-free, and complete remission at Week 52 compared to 22.4% of those taking a placebo, according to the company.
Amgen says the most common adverse reactions in patients with IgG4-RD were urinary tract infections (12% of patients treated) and lymphopenia (19%).
