What was measured

PFS was defined as the time from randomization until PD or death whichever occurred first, estimated using the Kaplan-Meier method. 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 and appearance of new lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.

Analysis population: ITT population included all participants randomized in the study.

Groups in this outcome

Mirvetuximab Soravtansine

Participants received mirvetuximab soravtansine at 6 mg/kg AIBW administered IV on Day 1 of a 3 week cycle. Participants continued to receive study drug until they experienced PD per RECIST version 1.1 (as assessed by BIRC), experienced unacceptable toxicity, or withdrew consent, whichever came first, or until the sponsor terminated the study. (Maximum exposure: 86.9 weeks)

Investigator's Choice (IC) Chemotherapy

Participants received a dose of 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. Participants continued to receive study drug until they experienced PD per RECIST version 1.1 (as assessed by BIRC), experienced unacceptable toxicity, or withdrew consent, whichever came first, or until the sponsor terminated the study. (Maximum exposure: 62.9 weeks)
