Study Details

Substudy 03A is part of a larger research study that is testing experimental treatments for renal cell carcinoma (RCC). The larger study is the umbrella study (U03). The goal of substudy 03A is to evaluate the safety and efficacy of experimental combinations of investigational agents in participants with advanced first line (1L) clear cell renal cell carcinoma (ccRCC). This substudy will have two phases: a safety lead-in phase and an efficacy phase. The safety lead-in phase will be used to demonstrate a tolerable safety profile for the combination of investigational agents. There will be no hypothesis testing in this study.

Arms

  • Experimental: Coformulation Pembrolizumab/Quavonlimab + Lenvatinib
    Participants will receive pembrolizumab/quavonlimab (coformulation of pembrolizumab 400 mg and quavonlimab 25 mg) PLUS lenvatinib 20 mg. Pembrolizumab/quavonlimab will be administered intravenously (IV) once every 6 weeks (Q6W) for up to 17 administrations (up to \~2 years). Lenvatinib will be administered orally once-daily (QD) until progressive disease or discontinuation.
  • Experimental: Coformulation Favezelimab/Pembrolizumab+ Lenvatinib
    Participants will receive favezelimab/pembrolizumab (coformulation of favezelimab 800 mg and pembrolizumab 200 mg) PLUS lenvatinib 20 mg. Favezelimab/Pembrolizumab will be administered IV once every 3 weeks (Q3W) for up to 35 administrations (up to \~2 years). Lenvatinib will be administered orally QD until progressive disease or discontinuation.
  • Experimental: Pembrolizumab + Belzutifan + Lenvatinib
    Participants will receive pembrolizumab 400 mg PLUS belzutifan 120 mg PLUS lenvatinib 20 mg. Pembrolizumab will be administered IV Q6W for up to 17 administrations (up to \~2 years). Both belzutifan and lenvatinib will be administered orally QD until progressive disease or discontinuation.
  • Experimental: Pembrolizumab + Lenvatinib
    Participants will receive pembrolizumab 400 mg PLUS lenvatinib 20 mg. Pembrolizumab will be administered IV Q6W for up to 17 administrations (up to \~ 2 years). Lenvatinib will be administered orally QD until progressive disease or discontinuation.
  • Experimental: Coformulation Vibostolimab/Pembrolizumab+Belzutifan
    Participants will receive vibostolimab/pembrolizumab (coformulation of 200 mg vibostolimab and pembrolizumab 200 mg). Vibostolimab/pembrolizumab will be administered IV once every 3 weeks (Q3W) for up to 35 administrations (up to \~2 years). Belzutifan will be administered orally QD until progressive disease or discontinuation.
