Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Mirvetuximab Soravtansine
Treatment: Drugs - Paclitaxel
Treatment: Drugs - Topotecan
Treatment: Drugs - Pegylated liposomal doxorubicin

Experimental: Mirvetuximab Soravtansine - Participants will receive single-agent mirvetuximab soravtansine (MIRV) at 6 milligrams (mg)/kilogram (kg) adjusted ideal body weight (AIBW) administered intravenously (IV) on Day 1 of every 3-week cycle (Q3W).

Active comparator: Investigator's Choice (IC) Chemotherapy - Participants will receive a dose of IC chemotherapeutic agent calculated using body surface area (BSA). Paclitaxel administered at 80 milligrams/square meter (mg/m\^2) as a 1-hour IV infusion on Days 1, 8, 15, and 22 of a 4-week cycle; or topotecan administered at 4 mg/m\^2 over 30 minutes on Days 1, 8, and 15 of a 4-week cycle. Alternatively, topotecan could be administered at 1.25 mg/m\^2 over 30 minutes on Days 1 to 5 of a 3-week cycle; or pegylated liposomal doxorubicin administered at 40 mg/m\^2 as a 1 mg/minute IV infusion on Day 1 of a 4-week cycle. After Cycle 1, if tolerated, pegylated liposomal doxorubicin could be administered as a 1-hour infusion.

2. Participants who have received 2 or 3 lines of platinum therapy must have progressed on or within 6 months after the date of the last dose of platinum Note: Progression should be calculated from the date of the last administered dose of platinum therapy to the date of the radiographic imaging showing progression. Note: Participants who are platinum-refractory during front-line treatment are excluded
4. Participants must have progressed radiographically on or after their most recent line of therapy
5. Participants must be willing to provide an archival tumor tissue block or slides, or undergo procedure to obtain a new biopsy using a low risk, medically routine procedure for immunohistochemistry (IHC) confirmation of FRa positivity

7. Participants must have at least one lesion that meets the definition of measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (radiologically measured by the Investigator)
8. Participants must have received at least 1 but no more than 3 prior systemic lines of anticancer therapy, and for whom single-agent therapy is appropriate as the next line of treatment:

1. Adjuvant ± neoadjuvant considered one line of therapy
2. Maintenance therapy (for example, bevacizumab, poly (ADP-ribose) polymerase [PARP] inhibitors) will be considered as part of the preceding line of therapy (that is, not counted independently)
3. Therapy changed due to toxicity in the absence of progression will be considered as part of the same line (that is, not counted independently)
4. Hormonal therapy will be counted as a separate line of therapy unless it was given as maintenance
9. Participant must have an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 or 1

Summary
Brief summary
This Phase 3 study is designed to compare the efficacy and safety of mirvetuximab soravtansine (MIRV) vs. IC chemotherapy in participants with platinum-resistant high-grade epithelial ovarian cancer, primary peritoneal, or fallopian tube cancer, whose tumors express a high-level of FRa. Participants will be, in the opinion of the Investigator, appropriate for single-agent therapy for their next line of therapy. The FRa positivity will be defined by the Ventana FOLR1 (FOLR1-2.1) CDx assay.
