Overview
This is a Phase 1 open-label, dose escalation study to evaluate the safety and efficacy of CT-95 (study drug), a humanized T cell engaging bispecific antibody targeting Mesothelin, in subjects with advanced solid tumors associated with Mesothelin expression.
Description
This Phase 1 dose escalation trial will enroll subjects into one of approximately 8 dose escalation cohorts to assess safety, tolerability and to determine the maximum tolerated dose or recommended dose. CT-95 is to be administered once weekly (Q1W) for each cycle. A cycle is defined as 28 days. Subjects will be dosed until documentation of disease progression, unacceptable toxicity, or subject/physician decision.
