Abstract

Background: The combination of nivolumab and ipilimumab is approved in several jurisdictions (United States, European Union, Canada) for the first-line treatment of patients with advanced melanoma. CheckMate 218 is a North American expanded-access program (EAP) of nivolumab plus ipilimumab in patients with advanced melanoma. Here, we report safety and survival outcomes for the Canadian cohort in the eap. Methods: Eligible patients were those 18 years of age or older with unresectable stage III or IV melanoma, an Eastern Cooperative Oncology Group performance status of 0 or 1, and no prior anti–PD-1 or anti–CTLA-4 therapy. Patients were treated with nivolumab 1 mg/kg and ipilimumab 3 mg/kg every 3 weeks for 4 cycles (induction phase); they then continued with nivolumab 3 mg/kg every 2 weeks (maintenance phase) until progression, unacceptable toxicity, or a maximum of 48 weeks, whichever occurred first. Safety and overall survival (OS) data were collected. Results: Of 194 patients enrolled, 174 were treated, and 51% continued on nivolumab maintenance. Median follow-up was 12.9 months. All-grade and grades 3–4 treatment-related adverse events were reported in 98% and 60% of patients respectively and led to treatment discontinuation in 40% and 28% of patients. Two treatment-related deaths were reported. The 12- and 18-month OS rates were 80% [95% confidence interval (CI): 73% to 86%] and 76% (95% CI: 67% to 82%) respectively. Conclusions: In this Canadian population, nivolumab plus ipilimumab demonstrated a safety profile and survival outcomes consistent with phase II and III clinical trial data.
