Systematic review of safety and efficacy of belimumab in treating immune-mediated disorders.

Belimumab is both safe and effective for the treatment of systemic lupus erythematosus. Results were further promising for the use of belimumab in patients with rheumatoid arthritis and Sjögren's syndrome. Conversely, results using belimumab in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis and myasthenia gravis were rather disappointing.
