A Study to Evaluate the Safety and Efficacy of OPB-101 in Platinum-resistant Ovarian Cancer

What this study is about

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.
