What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 30 participants in total. It began in 2025-06-16 with a primary completion date of 2028-05-15.

Brief Summary

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.
