| Eligible Participant | Platinum sensitive ovarian cancer with CR or PR in most recent Pt-based therapy, with prior PARP inhibitor maintenance |
| Patients Enrolled | 220; median 4 prior therapies |
| Therapy Setting | Maintenance |
| Study Design | Double Blind, Randomized |
| Endpoints | PFS, evaluated per RECIST |
