Summary

This study compares a new biosimilar drug (GME751) to the standard immunotherapy Keytruda in 322 adults with stage II or III melanoma that has been surgically removed. The goal is to see if the biosimilar stays in the body and works as well as Keytruda in preventing the cancer from coming back. Participants receive either drug as an infusion every few weeks, and researchers monitor drug levels, safety, and immune response.
