A Study of Atezolizumab in Combination With Bevacizumab Versus Sunitinib in Participants With Untreated Advanced Renal Cell Carcinoma (RCC)

This multi-center, randomized, open-label study will evaluate the efficacy and safety of atezolizumab plus bevacizumab versus sunitinib in participants with inoperable, locally advanced, or metastatic RCC who have not received prior systemic active or experimental therapy, either in the adjuvant or metastatic setting.
