Phase 1/1b Study to Evaluate the Safety and Tolerability of CPI-444 Alone and in Combination With Atezolizumab in Advanced Cancers
This is a phase 1/1b open-label, multicenter, dose-selection study of CPI-444, 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 CPI-444 as a single agent and in combination with atezolizumab, a PD-L1 inhibitor against various solid tumors. CPI-444 blocks adenosine from binding to the A2A receptor. Adenosine suppresses the anti-tumor activity of T cells and other immune cells.
