Clinical Trial Summary

The Purpose of this study is to investigate the safety, tolerability, pharmacokinetics, and preliminary efficacy of hSTC810 monotherapy in participants with advanced solid tumors.

Description:

The study consists of a dose-escalation phase that will evaluate 6 dosing schedules of hSTC810. The first cohort will be single participant cohort. Subsequent escalation cohorts will use a standard 3+3 design, with the ability to backfill up to an additional 6 patients in each dose cohort.
