Summary
The purpose of this study is to learn if V940 which is an individualized neoantigen
therapy (INT; formerly, called messenger ribonucleic acid [mRNA]-4157) with pembrolizumab
(MK-3475) is safe and prevents cancer from returning in people with high-risk melanoma.
Researchers want to know if V940 with pembrolizumab is better than receiving
pembrolizumab alone at preventing the cancer from returning.
