Ipilimumab Therapy in Patients With Advanced Melanoma and Preexisting Autoimmune Disorders

Abstract
Ipilimumab is a monoclonal antibody to cytotoxic T-lymphocyte antigen 4 (CTLA-4) that induces antitumor immune responses by removing a key negative regulator of T cell activation. This antibody was the first agent to demonstrate improved overall survival for patients with advanced melanoma and received regulatory approval in 2011.1,2 Furthermore, durable benefits have been observed, with approximately 20% of patients surviving at least 5 years.3,4
