Purpose: The clinical activity observed in a phase I dose-escalation study of concurrent therapy with nivo-lumab (NIVO) and ipilimumab (IPI) in patients with previously treated or untreated advanced melanoma led to subsequent clinical development, including randomized trials. Here, we report longterm follow-up data from study CA209-004, including 3-year overall survival (OS). Patients and Methods: Concurrent cohorts 1, 2, 2a, and 3 received escalating doses of NIVO plus IPI once every 3 weeks for four doses, followed by NIVO once every 3 weeks for four doses, then NIVO plus IPI once every 12 weeks for eight doses. An expansion cohort (cohort 8) received concurrent NIVO 1 mg/kg plus IPI 3 mg/kg once every 3 weeks for four doses, followed by NIVO 3 mg/kg once every 2 weeks, which is the dose and schedule used in phase II and III studies and now approved for patients with unre-sectable or metastatic melanoma. Results: Among all concurrent cohorts (N = 94) at a follow-up of 30.3 to 55.0 months, the 3-year OS rate was 63% and median OS had not been reached. Objective response rate by modified WHO criteria was 42%, and median duration of response was 22.3 months. Incidence of grade 3 and 4 treatment-related adverse events was 59%. The most common grade 3 and 4 treatment-related adverse events were increases in lipase (15%), alanine aminotransferase (12%), and aspartate amino-transferase (11%). One treatment-related death (1.1%) occurred in a patient who had multiorgan failure 70 days after the last dose of NIVO plus IPI. Conclusion: This is the longest follow-up for NIVO plus IPI combination therapy in patients with advanced melanoma. The 3-year OS rate of 63% is the highest observed for this patient population and provides additional evidence for the durable clinical activity of immune checkpoint inhibitors in the treatment of advanced melanoma.
