New biosimilar aims to match keytruda in melanoma fight

NCT ID NCT06551064

First seen Nov 01, 2025 · Last updated May 09, 2026 · Updated 30 times

Summary

This study compares FYB206, a biosimilar (a very similar copy) of the cancer drug Keytruda, to the original Keytruda in 96 adults with stage IIB/IIC or III melanoma that has been completely removed by surgery. The goal is to see if FYB206 stays in the body the same way as Keytruda, which helps the immune system attack cancer cells and prevent the cancer from coming back. Participants will receive either FYB206 or Keytruda after surgery, and researchers will measure drug levels and safety.
