Study Summary

This is a Phase 1, open-label, dose-escalation and dose-expansion study to evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD) and clinical activity of etrumadenant (AB928) in combination with zimberelimab (AB122) (an anti-PD-1 antibody) in participants with advanced malignancies.

Primary Outcome

Safety will be assessed by monitoring adverse events and clinically relevant changes in Eastern Cooperative Oncology Group (ECOG) performance status, 12 lead Electrocardiogram (ECG), vital signs, physical examination and clinical laboratory results.
