This trial has met its accural targets Wednesday, November 15, 2017 The MEC.5 trial, A Phase III Randomized Trial Comparing Physician/Patient Choice of Either High Dose Interferon or Ipilimumab to MK-3475 (Pembrolizumab) in Patients with High Risk Resected Melanoma, is closed further accrual as of November 2nd, 2017. This trial met its accrual goal and was subsequently closed to registrations. This randomized phase III trial studies how well high-dose recombinant interferon alfa-2B or ipilimumab works compared with pembrolizumab in treating patients with stage III-IV melanoma that has been removed by surgery but is likely to come back or spread. High-dose recombinant interferon alfa-2B may help shrink or slow the growth of melanoma. Monoclonal antibodies, such as ipilimumab and pembrolizumab, may block tumor growth in different ways by targeting certain cells. It is not yet known whether high-dose recombinant interferon alfa-2B or ipilimumab is more effective than pembrolizumab in treating patients with melanoma. Primary Objectives: a.Compare overall survival (OS) of patients with resected Stage III and IV melanoma treated with high dose interferon alfa-2b versus MK-3475 (pembrolizumab) b.Among patients who are PD-L1 positive, to compare OS of patients with resected Stage III and IV melanoma treated with high dose interferon alfa-2b versus MK-3475 (pembrolizumab) c.Compare relapse-free survival (RFS) of patients with resected Stage III and IV melanoma treated with high dose interferon alfa-2b to MK-3475 (pembrolizumab) d.Among patients who are PD-L1 positive, to compare RFS of patients with resected Stage III and IV melanoma treated with high dose interferon alfa-2b to MK-3475 (pembrolizumab) Secondary Objectives: a. Estimate OS and RFS for patients who are PD-L1 negative or PD-L1 indeterminate in this population. b. Compare OS and RFS of patients between the two regimens within PD-L1 positive and negative subgroups and to look at the interaction between PD-L1 and treatment arm.
