Substudy 03C: A Study of Combination Therapies in Participants With Renal Cell Carcinoma With Recurrent Disease During or After Anti-PD-(L)1 Therapy (MK-3475-03C/KEYMAKER-U03)

Summary

Substudy 03C 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 03C is to evaluate the safety and efficacy of experimental combinations of investigational agents in participants with clear cell renal cell carcinoma (ccRCC) who have recurrent disease during or after anti-programmed cell death 1/programmed cell death ligand 1 (PD-\[L\]1) adjuvant therapy. 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

Eligibility

The main inclusion criteria include but are not limited to the following:

* Has a histologically confirmed diagnosis of unresectable locally advanced/metastatic renal cell carcinoma (RCC) with clear cell component
* Has received no other prior systemic therapy for treatment of advanced/metastatic clear cell renal cell carcinoma (ccRCC) except for adjuvant programmed cell death ligand 1 (PD-(L)1) therapy
* Has disease recurrence during adjuvant anti- PD-(L)1 therapy or ≤24 months following the last dose of adjuvant anti-PD-(L)1 therapy
* Is able to swallow oral medication
* Submits an archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated
* Participants receiving bone resorptive therapy (must have therapy initiated at least 2 weeks before allocation/randomization)

* Has received a live or live attenuated vaccine within 30 days before the first dose of study intervention
* Is currently receiving anticoagulants or platelet inhibitors that cannot be discontinued for the duration of the study
* Have been previously allocated/randomized to study intervention in any sub study of protocol MK-3475-U03
* Has a known additional malignancy that is progressing or has required active treatment within the past 3 years
* Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis
* Has radiographic evidence of encasement or invasion of a major blood vessel, or of intratumoral cavitation
* Has active autoimmune disease that has required systemic treatment in the past 2 years
* Has an active infection requiring systemic therapy
* Has history of human immunodeficiency virus (HIV) infection
* Has hepatitis B or hepatitis C virus infection
