What was measured

Overall survival was defined as the time from the date of first dose until the date of death from any cause, estimated using the Kaplan-Meier method.

Analysis population: The ITT population included all participants randomized to the study, regardless of whether or not participants received study treatment (MIRV or IC Chemo).

Groups in this outcome

Mirvetuximab Soravtansine

Participants randomized to single-agent MIRV at 6 mg/kg AIBW administered IV on Day 1 of Q3W.

Investigator's Choice (IC) Chemotherapy

Participants randomized to IC chemotherapeutic agent calculated using BSA. Paclitaxel administered at 80 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 have been 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 have been administered as a 1-hour infusion.
