The U.S. Food and Drug Administration approved Benlysta (belimumab) intravenous (IV) infusion for treatment of children with systemic lupus erythematosus (SLE) - often referred to as simply "lupus" - a serious chronic disease that causes inflammation and damage to various body tissues and organs. This is the first time that the FDA has approved a treatment for pediatric patients with SLE. Benlysta has been approved for use in adult patients since 2011.
