Brief Summary

This is a multicenter randomized double-blind placebo-controlled phase II clinical trial. The purpose of this trial is to evaluate efficacy and safety of therapy consisting of BCD-217 (fixed dose combination of anti-CTLA-4 and anti-PD-1 monoclonal antibodies) and sequential BCD-100 (anti-PD-1 monoclonal antibody) versus BCD-100 monotherapy as first-line treatment in patients with treatment-naïve unresectable or metastatic melanoma.

Conditions
