Descriptive Information

• Brief Title: CPI-006 Alone and in Combination With Ciforadenant and With Pembrolizumab for Patients With Advanced Cancers
• Official Title: A PHASE 1/1b MULTICENTER STUDY TO EVALUATE THE HUMANIZED ANTI-CD73 ANTIBODY, CPI-006, AS A SINGLE AGENT OR IN COMBINATION WITH CIFORADENANT, WITH PEMBROLIZUMAB, AND WITH CIFORADENANT PLUS PEMBROLIZUMAB IN ADULT SUBJECTS WITH ADVANCED CANCERS
• Brief Summary: This is a Phase 1/1b open-label, dose escalation and dose expansion study of CPI-006, a humanized monoclonal antibody (mAb) targeting the CD73 cell-surface ectonucleotidase in adult subjects with select advanced cancers. CPI-006 will be evaluated as a single agent, in combination with ciforadenant (an oral adenosine 2A receptor antagonist), in combination with pembrolizumab (an anti-PD1 antibody), and in combination with ciforadenant and pembrolizumab.
