Details and patient eligibility

About

The primary purpose of this study is to compare pembrolizumab/vibostolimab to pembrolizumab with respect to recurrence-free survival (RFS). The primary hypothesis is that pembrolizumab/vibostolimab is superior to pembrolizumab with respect to RFS as assessed by the investigator in participants with high-risk resected Stage IIB, IIC, III and IV melanoma.

Full description

With Amendment 4, participants will discontinue treatment with pembrolizumab/vibostolimab. No formal analysis of RFS will occur and no analysis of distant metastasis-free survival (DMFS), overall survival (OS), or change from baseline in the European Organization for Research and Treatment of Cancer (EORTC)-Quality of Life Questionnaire-Core 30 (QLQ-C30) outcome measures will occur.
