Detailed Description
This is a multicenter, open-label Phase 1b/2 study in participants with metastatic colorectal cancer that will assess the antitumour activity and safety of etrumadenant.
Approximately 250 participants will be enrolled to 1 of 3 cohorts:
Cohort A) etrumadenant + zimberelimab +mFOLFOX-6 +/-bevacizumab vs mFOLFOX-6 +/-bevacizumab
Cohort B) etrumadenant + zimberelimab +mFOLFOX-6 +/-bevacizumab vs regorafenib
Cohort C) chemotherapy-free combinations of etrumadenant + zimberelimab + other agents
The primary objective of this clinical study is to evaluate the safety of etrumadenant-based combination therapy in participants with metastatic colorectal cancer.
