This study is designed to evaluate the efficacy and safety of mirvetuximab soravtansine (MIRV) in participants with platinum-resistant high-grade serous epithelial ovarian cancer, primary peritoneal, or fallopian tube cancer, whose tumors express a high-level of Folate Receptor-Alpha (FRα). Participants will be, in the opinion of the Investigator, appropriate for single-agent therapy for their next line of therapy. All participants will receive single-agent MIRV at 6 mg/kg adjusted ideal body weight administered on Day 1 of every 3-week cycle.

- description
- ORR was defined as percentage of participants with a confirmed best overall response (BOR) of complete response (CR) or partial response (PR). CR: Disappearance of all target or non-target lesions. All pathological or non-pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 millimeters (mm). PR: At least 30% decrease in the sum of the longest diameters (SoD) of target lesions, taking as reference the baseline SoD.

- description
- DOR was defined as the time from the date of the first response (CR or PR), until the date of progressive disease (PD) or death from any cause, whichever occurred first. DOR for participants who had not progressed or died at the time of analysis was censored at the date of their last tumor assessment. PD: At least a 20% increase in the SoD of target lesion, taken as reference the smallest (nadir) SoD since and including baseline. In addition to the relative increase of 20%, the SoD must also demonstrate an absolute increase of at least 5 mm. Unequivocal progression of non-target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase. DOR was estimated using the Kaplan-Meier method.

- brief Summary
- This study is designed to evaluate the efficacy and safety of mirvetuximab soravtansine (MIRV) in participants with platinum-resistant high-grade serous epithelial ovarian cancer, primary peritoneal, or fallopian tube cancer, whose tumors express a high-level of Folate Receptor-Alpha (FRα).

- detailed Description
- This study is designed to evaluate the efficacy and safety of mirvetuximab soravtansine (MIRV) in participants with platinum-resistant high-grade serous epithelial ovarian cancer, primary peritoneal, or fallopian tube cancer, whose tumors express a high-level of Folate Receptor Alpha (FRα). Participants will be, in the opinion of the Investigator, appropriate for single-agent therapy for their next line of therapy. FRα positivity will be defined by the Ventana FOLR1 (Folate Receptor 1/Folate Receptor Alpha) Assay. Approximately 110 eligible participants will be enrolled to achieve a total of 105 efficacy evaluable participants. Efficacy evaluable participants include those who have measurable lesions per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) at baseline and received at least 1 dose of MIRV. All participants will receive single-agent MIRV at 6 mg/kg adjusted ideal body weight (AIBW) administered on Day 1 of every 3-week cycle (Q3W). Tumor response will be evaluated by the Investigator using RECIST v1.1. Computerized tomography (CT) or magnetic resonance imaging (MRI) scans will be collected for sensitivity analysis by blinded independent central review (BICR). Participants will continue to receive MIRV until disease progression, unacceptable toxicity, withdrawal of consent, death, or until the Sponsor terminates the study (whichever comes first). Tumor assessments, including radiological assessments by CT/MRI scans will be performed at Screening and subsequently every 6 weeks (± 1 week) from Cycle 1 Day 1 (C1D1) for the first 36 weeks then every 12 weeks (± 3 weeks) until disease progression, death, the start of new anticancer therapy, or participant's withdrawal of consent (whichever occurs first). Participants who discontinue MIRV for reasons other than progressive disease (PD) will continue with tumor assessments until documentation of PD or the start of a new anticancer therapy, whichever comes first. Prior to Week 36 (from Cycle 1, Day 1), assessments should occur every 6 weeks (± 1 week) as allowed by local requirements but must occur at an interval of no more than 12 weeks. After Week 36, assessment will occur every 12 weeks (± 3 weeks) until documentation of PD or the start of new anticancer therapy. All participants who discontinue MIRV will be followed for survival every 3 months (± 1 month) until death, lost to follow-up, withdrawal of consent for survival follow-up, or end of study (EOS) (whichever comes first). Additional survival follow-up calls may occur periodically, if needed.
