Brief Summary

This is a Phase 1b/2, open-label, dose escalation, dose expansion and dose optimization study to evaluate the safety, tolerability, PK, and immunogenicity of ADG126-pembrolizumab combination regimens in patients with advanced/metastatic solid tumors. The study drug ADG126 is an anti-CTLA-4 fully human monoclonal antibody that specifically binds to human CTLA-4. Pembrolizumab is a PD-1 receptor-blocking antibody (a humanized IgG4 monoclonal antibody).
