New keytruda copycat tested in melanoma patients after surgery

This study tests a new drug called Bmab1800 to see if it works like the approved drug Keytruda in people with stage IIB, IIC, or III melanoma after their tumor has been removed by surgery. About 138 adults will get either Bmab1800 or Keytruda, and researchers will compare how the drug moves through the body, its safety, and whether the body fights it. The goal is to see if Bmab1800 is a safe and effective alternative to Keytruda for preventing melanoma from coming back.
