This open-label study will assess the safety and efficacy of the combination of IMM-101 with nivolumab in patients with unresectable stage III, or stage IV melanoma who are either treatment-naive (cohort A) or whose disease has progressed during PD-1 blockade (cohort B). Ipilimumab may be used as a subsequent treatment in place of nivolumab alongside IMM-101 for patients in cohort B if their disease progresses on study. Eighteen patients will be enrolled into cohort A and 8 patients into cohort B.
The purpose of this study is to assess the safety and efficacy of the combination of IMM-101 with nivolumab.
