Substudy 02B: Safety and Efficacy of Pembrolizumab in Combination With Investigational Agents or Pembrolizumab Alone in Participants With First Line (1L) Advanced Melanoma (MK-3475-02B/KEYMAKER-U02)

Study Purpose

Substudy 02B 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 02B is to evaluate the safety and efficacy of investigational treatment arms in participants with 1L advanced melanoma and to identify the investigational agent(s) that, when used in combination, are superior to the current treatment options/pembrolizumab monotherapy. Arm 1: Pembrolizumab + Vibostolimab was added in the base protocol on 13-Nov-2019, and enrollment into this arm has been completed. Arm 2: Pembrolizumab was added in the base protocol on 13-Nov-2019, and enrollment stopped prematurely on 15-Aug-2022. Arm 3: Coformulation Pembrolizumab/Quavonlimab was added in Amendment 01 on 20-Oct-2020, and enrollment stopped prematurely on 15-Aug-2022. Arm 4: Coformulation Pembrolizumab/Quavonlimab + Lenvatinib was added in Amendment 01 on 20-Oct-2020, and enrollment is ongoing. Arm 5: Coformulation Favezelimab/Pembrolizumab, Arm 6: Coformulation Favezelimab/Pembrolizumab + All-trans Retinoic Acid (ATRA), and Arm 7: Coformulation Favezelimab/Pembrolizumab + Vibostolimab were added in Amendment 04 on 10-May-2023, and enrollment for these arms will be initiated in July 2023.
