Clinical Trial Summary

This is a phase 1 study designed to evaluate the safety, tolerability, and antitumor activity of FT825 (also known as ONO-8250) with or without monoclonal antibody therapy following chemotherapy in participants with advanced human epidermal growth factor receptor 2 (HER2)-positive or other advanced solid tumors. The study will consist of a dose-escalation stage, followed by an expansion stage to further evaluate the safety and activity of FT825 in indication-specific cohorts.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with dose limiting toxicities (DLTs)	The number of participants with DLTs will be reported.	Up to approximately 29 days
Primary	Number of participants with treatment-emergent adverse events (TEAEs)	The number of participants with TEAEs will be reported.	Up to approximately 2 years
Primary	Severity of AEs	Severity of AEs will be determined according to appropriate rating scales for the type of event reported.	Up to approximately 2 years
Secondary	Investigator-Assessed Overall Response Rate (ORR)	ORR is the proportion of participants who achieve partial response (PR) or complete response (CR) per Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST, v.1.1).	Up to approximately 2 years
Secondary	Investigator-Assessed Duration of Response (DOR)	DOR is the duration from the first occurrence of a documented objective response of either PR or CR until the time of disease progression, or death from any cause, whichever occurs first, per RECIST, v.1.1.	Up to approximately 2 years
Secondary	Progression-Free Survival (PFS)	PFS is the time from first dose of study intervention to disease progression, or to the day of death for any reason, whichever occurs first, per RECIST, v.1.1.	Up to approximately 2 years
Secondary	Overall Survival (OS)	OS defined as the time from first dose of study intervention to death from any cause.	Up to approximately 2 years
Secondary	Plasma Concentration of FT825	The plasma concentration of FT825 will be determined.	At designated time points up to approximately 56 days
