Adjuvant Pembrolizumab versus IFNa2b or Ipilimumab in Resected High-Risk Melanoma. Cancer Discovery OF1-OF10, 2022. https://doi.org/10.1158/2159-8290.CD-21-1141 About MEC5 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. Immunotherapy with monoclonal antibodies, such as ipilimumab and pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether high-dose recombinant interferon alfa-2B or ipilimumab is more effective than pembrolizumab in treating patients with melanoma.
