Phase 1/1b Study to Evaluate the Safety and Tolerability of Ciforadenant Alone and in Combination With Atezolizumab in Advanced Cancers

Phase 1
Completed
Conditions
Renal Cell Cancer
Metastatic Castration Resistant Prostate Cancer
Interventions
Registration Number
NCT02655822
Lead Sponsor
Corvus Pharmaceuticals, Inc.
Brief Summary

This is a phase 1/1b open-label, multicenter, dose-selection study of ciforadenant, an oral small molecule targeting the adenosine-A2A receptor on T-lymphocytes and other cells of the immune system. This trial will study the safety, tolerability, and anti-tumor activity of ciforadenant as a single agent and in combination with atezolizumab, a PD-L1 inhibitor against various solid tumors. Ciforadenant blocks adenosine from binding to the A2A receptor. Adenosine suppresses the anti-tumor activity of T cells and other immune cells.

Detailed Description

This trial will study the safety, tolerability, and anti-tumor activity of ciforadenant as a single agent and in combination with atezolizumab, an intravenous PD-L1 inhibitor. Ciforadenant blocks adenosine from binding to the A2A receptor. Adenosine suppresses the anti-tumor activity of T cells and other immune cells.
