Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if OPB-101 is safe in platinum resistant ovarian cancer participants and also to find the optimal dose of OPB-101.

Participants will have their own T cells modified in a laboratory and given back to them as OPB-101 in this one-time treatment. Participants will be in the hospital when they receive OPB-101 and then be checked at the clinical site frequently for the first few months.

Detailed Description

A phase 1a/b study to evaluate the safety and efficacy of OPB-101, an autologous mesothelin (MSLN) CAR T cell therapy with antigen-dependent expression of OUTSMART™ designed IL-2 cytokine in platinum-resistant ovarian cancer.
