Study Summary

This is a Phase 1, open-label, multicenter, single-arm, dose escalation study, designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of single-agent ASC61(an orally bioavailable small-molecule inhibitor of PD-L1) in subjects with advanced solid tumors for whom no standard therapy is available.

Primary Outcome

The primary endpoint of this study is the proportion of the patients who experience DLTs. The MTD (Maximum Tolerated Dose) will be determined based on the dose escalation cohorts. The evaluation period for DLTs will be 28 days following treatment of PD1-PDL1 inhibitor
