Summary

This trial is testing a new drug, mirvetuximab soravtansine, to see if it is more effective and has fewer side effects than existing chemotherapy drugs for people with ovarian cancer.

Who is the study for?

This trial is for women over 18 with high-grade ovarian, primary peritoneal, or fallopian tube cancers that are resistant to platinum-based chemotherapy and have high folate receptor-alpha expression. Participants must have received 1-3 prior cancer treatments and be suitable for single-agent therapy. They should not be pregnant, agree to use contraception, and cannot have certain health conditions or a history of severe reactions to the study drugs.

What is being tested?

The study compares mirvetuximab soravtansine (a targeted cancer drug) against the investigator's choice of standard chemotherapy (paclitaxel, pegylated liposomal doxorubicin, or topotecan). The goal is to see which treatment is more effective and safer for patients whose tumors express a lot of folate receptor-alpha.

What are the potential side effects?

Possible side effects include allergic reactions to the drugs used in this trial; nerve damage; eye problems like corneal disorders; blood clots; heart issues; liver disease symptoms worsening if pre-existing; increased risk of infections due to weakened immune system.

Experimental Treatment

Active Control

Group I: Mirvetuximab SoravtansineExperimental Treatment1 Intervention

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).

Group II: Investigator's Choice (IC) ChemotherapyActive Control3 Interventions

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.
