The KEYVIBE program: vibostolimab and pembrolizumab for the treatment of advanced malignancies.
Summary
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.
