A Study Evaluating the Efficacy and Safety of Sunitinib With or Without Bevacizumab in First-Line Patients With Metastatic Renal Cell Cancer (SABRE-R)

Study Overview
=================
Brief Summary
-----------------
This is a Phase II, multicenter, randomized, blinded, placebo-controlled study designed to evaluate the safety and efficacy of combining bevacizumab with sunitinib relative to placebo with sunitinib in patients with metastatic RCC who have not received prior systemic therapy for metastatic disease. The study will enroll approximately 100 patients at approximately 20 centers in the United States.
