Substudy 02D: Safety and Efficacy of Pembrolizumab in Combination With Investigational Agents or Pembrolizumab Alone in Participants With Melanoma Brain Metastasis (MK-3475-02D/KEYMAKER-U02)

About

Brief Summary

Substudy 02D is part of a larger research study that is testing experimental treatments for melanoma, a type of skin cancer. The larger study is the umbrella study.

The goal of substudy 02D is to evaluate the safety and efficacy of investigational treatment arms in programmed cell-death 1 (PD-1) naïve or PD-1 exposed participants with melanoma brain metastasis (MBM) and to identify the investigational agent(s) that, when used in combination, are superior to the current treatment options/historical control available.
