A Retrospective Observational Study Comparing Nivolumab + Ipilimumab Combination vs. Nivolumab Monotherapy as First Line Treatment of Metastatic PD-L1 Positive Melanoma in the US

The goal of this study is to describe patient characteristics, treatment outcomes and adverse events for patients with metastatic melanoma testing positive for PD-L1 expression treated first line (1L) with either nivolumab and ipilimumab in combination (NIVO + IPI) or nivolumab (NIVO) monotherapy

• Initiating a first line of therapy during the index period between October 1, 2015 through July 1, 2017
• Medical history available for medical chart abstraction from date of diagnosis through most recent or current therapy (defined as end of data collection period)
