CPI-006 Alone and in Combination With CPI-444 and With Pembrolizumab for Patients With Advanced Cancers

This is a phase 1 / 1b open label, multicenter, dose-selection study of CPI-006, a Type 2 humanized IgG1 antibody inhibiting enzymatic activity of CD73 and adenosine production. This trial will study the safety, tolerability, and anti-tumor activity of CPI-006 as a single agent, in combination with CPI-444, a small molecule targeting the adenosine-A2A receptor on immune cells, and in combination with pembrolizumab, an anti-PD1 antibody against various solid tumors and Non-Hodgkin lymphoma.
