| Drugs in Trial | Bevacizumab, Mirvetuximab soravtansine |
| Eligible Participant | Platinum sensitive FRalpha+ ovarian cancer; IHC: ≥ 25% tumor cells at ≥ 2+ intensity |
| Patients Enrolled | 31 |
| Therapy Setting | Recurrence |
| Study Design | Open-Label, Non-randomized |
| Endpoints | ORR, DoR, PFS, evaluated per RECIST |
| Biomarkers | Exploratory analysis: FRalpha high (IHC: ≥ 75% tumor cells at ≥ 2+ intensity) |
