Clinical Trial Summary

This is a Phase 1, open-label, dose escalation study in patients with advanced/metastatic solid tumors. Study drug, ADG116, is an anti -CTLA-4 fully human monoclonal antibody that specifically binds to human CTLA-4. ADG106, a fully human ligand-blocking agonistic anti-CD137 IgG4 mAb, is expected to enhance the activity of activated T cells. The enhanced antitumor efficacy results observed from the preclinical studies of ADG116 in combination with ADG106 or anti-PD-1 provided further support to explore such combinations in clinical settings for better patient responses.
