Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the efficacy and safety of pembrolizumab (MK-3475) in combination with axitinib versus sunitinib monotherapy as a first-line treatment for participants with advanced/metastatic renal cell carcinoma (mRCC).

The primary hypotheses of this study are:

1. The combination therapy of pembrolizumab plus axitinib is superior to sunitinib monotherapy with respect to Progression-Free Survival (PFS) as assessed by blinded independent central imaging review per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1)
2. The combination therapy of pembrolizumab plus axitinib is superior to sunitinib monotherapy with respect to Overall Survival (OS).

* Has measurable disease per RECIST 1.1 as assessed by the investigator/site radiologist
* Has received no prior systemic therapy for advanced RCC.
* Has provided archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated.
* Has Karnofsky performance status (KPS) ≥ 70% as assessed within 10 days prior to randomization.
* If receiving bone resorptive therapy (including but not limited to bisphosphonate or RANK-L inhibitor) must have therapy initiated at least 2 weeks prior to randomization.
* Demonstrates adequate organ function.
* Female participants of childbearing potential must be willing to use an adequate method of contraception for the course of the study through 120 days after the last dose of study drug.
* Male participants of childbearing potential must agree to use an adequate method of contraception, starting with the first dose of study drug through 120 days after the last dose of study drug.

Exclusion Criteria

* Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to randomization.
* Has had major surgery within 4 weeks, received radiation therapy within 2 weeks prior to randomization, or has not recovered (i.e., ≤ Grade 1 or at baseline) from AEs due to prior treatment.
* Has had prior treatment with any anti-programmed cell death (anti-PD-1), or programmed cell death ligand 1 (PD-L1), or PD-L2 agent or an antibody targeting any other immune-regulatory receptors or mechanisms.
* Has received prior systemic anti-cancer therapy for RCC with vascular endothelial growth factor (VEGF)/VEGF receptors (VEGFR) or mechanistic target of rapamycin (mTOR) targeting agents.
* Has a history of severe hypersensitivity reaction (e.g., generalized rash/erythema, hypotension, bronchospasm, angioedema or anaphylaxis) to axitinib or sunitinib.
