Brief Summary:
This study is a randomized Phase 2 evaluation of CB-839 in combination with cabozantinib versus placebo with cabozantinib in patients with advanced or metastatic Renal Cell Carcinoma.

Condition or disease Intervention/treatment Phase
Advanced Renal Cell Carcinoma Metastatic Renal Cell Carcinoma Drug: CB-839 Drug: Cabozantinib Drug: Placebo Phase 2

Detailed Description:
This study is a randomized Phase 2 evaluation of CB-839 in combination with cabozantinib versus placebo with cabozantinib in Renal Cell Carcinoma patients with at least one and not more than 2 prior therapies in the advanced or metastatic setting.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 298 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: This is a double blinded placebo-controlled study where patients will be randomized 1:1 to either CB-839 plus cabozantinib or placebo plus cabozantinib
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: Double-blind in place with blinded Independent Radiology Committee reviewing adjudicated progression free survival of patients
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo-Controlled Phase 2 Study Comparing CB-839 in Combination With Cabozantinib (CB-Cabo) vs. Placebo With Cabozantinib (Pbo-Cabo) in Patients With Advanced or Metastatic Renal Cell Carcinoma (RCC) - CANTATA
Actual Study Start Date : March 27, 2018
Estimated Primary Completion Date : June 30, 2020
Estimated Study Completion Date : June 30, 2022
