Phase IInterventional

A Phase 1a/b Study to Evaluate the Safety and Efficacy of OPB 201, an Autologous PReferentially Expressed Antigen of MElanoma (PRAME) T Cell Receptor (TCR) T Cell Therapy in Recurrent Endometrial and Platinum-resistant Ovarian Cancer.

Protocol: 2026P000798NCT: NCT07664735

Overview

The goal of this clinical trial is to learn if OPB-201 is safe in recurrent endometrial and platinum resistant ovarian cancer participants and also to find the optimal dose of OPB-201. Participants will have their own T cells modified in a laboratory and given back to them as OPB-201 in this one-time treatment. Participants will be in the hospital when they receive OPB-201 and then be checked at the clinical site frequently for the first few months.
