Belimumab Treatment for IgG4-related Disease

Summary

Even though glucocorticoid is the current first line medication for IgG4-RD, it is well accepted in the field that excessive dosage of GC, especially accumulative dosage, is associated with increasing organ damage. Although B cell depletion with rituximab has been verified to be an effective treatment for IgG4-RD, even without concomitant GC therapy, rituximab can increase the risk of infection during the treatment. Belimumab is an IgG1-lambda monoclonal antibody that prevents the survival of B lymphocytes by blocking the binding of soluble human B lymphocyte stimulator protein (BLyS) to receptors on B lymphocytes. Previous studies and trails suggested that the activity of B-cell mediated immunity and autoimmune responses were ameliorated after belimumab without increasing rates of adverse events when compared to standard of care . However, the efficacy and tolerability of belimumab in IgG4-RD patients have not been examined before. This randomized, control clinical trial aimed to evaluate the tolerability and the efficacy of Belimumab for maintenance treatment for IgG4-RD.
