Study Summary

The main purpose of the study is to evaluate the safety and tolerability of HRO761 and identify the recommended dose(s), i.e., the optimal safe and active dose of HRO761 alone or in combination with pembrolizumab or irinotecan that can be given to patients who have cancers with specific molecular alterations called MSIhi (Microsatellite Instability-high) or dMMR (Mismatch Repair Deficient) that might work best to treat these specific cancer types and to understand how well HRO761 is able to treat those cancers.

Primary Outcome

Month 36 is assumed to be study end. Incidence and severity of AEs and SAEs by treatment group, including changes in vital signs, electrocardiograms (ECGs) and laboratory results qualifying and reported as AEs.
