Study Endpoints
Primary Endpoints
Assess Progression-free survival (PFS)
Up to 4 years

Progression-free survival defined as assessed by BICR per RECIST v1.1, defined as the time from date of randomization until BICR-assessed PD or death due to any cause, whichever occurs first

Substudy 1, 2, and 3: Number of Participants with Treatment-Emergent Adverse Events (TEAEs) (any grade, Grade >= 3)
Up to Approximately 40 Months

TEAEs defined as any adverse event (AE) with the onset after the first dose of study drug until 30 days after the last dose of the study drug.

Substudy 1, 2, and 3: Number of Participants with TEAEs Leading to Discontinuation
Up to Approximately 40 Months

TEAEs defined as any adverse event (AE) with the onset after the first dose of study drug until 30 days after the last dose of the study drug.

Substudy 1, 2, and 3: Number of Participants with Ocular Adverse Events (AEs) (any grade, Grade >= 2)
Up to Approximately 40 Months

An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.

Substudy 1, 2, and 3: Overall Response (OR) as Assessed by the Investigator per RECIST v1.1
Up to Approximately 40 Months

OR is defined as achieving a best overall response of confirmed complete response (CR) or confirmed partial response (PR) based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Substudy 1: Progression free survival (PFS) as Assessed by the Investigator per RECIST v1.1
Up to Approximately 40 Months

PFS is defined as the time from the date of randomization to the first occurrence of radiographic progression based on RECIST version 1.1 or death from any cause, whichever occurs first.

Objective Response Rate (ORR) Assessed by Investigator Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1])
Up to 3 years

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.

progression free survival (PFS)
Baseline through 2 years

To assess percentage of patients with advanced-stage ovarian, fallopian tube, and peritoneal cancers per Response Evaluation Criteria in Solid Tumors (RECIST)1.1 and Gynecological Cancer Intergroup Cancer antigen 125 (GCIG CA-125) criteria.

Objective response rate (ORR)
Baseline through 2 years

To assess ORR per iRECIST 1.1 and GCIG CA-125 criteria

Radiographic tumor assessment per RECIST v1.1 criteria
Baseline through 2 years

Radiographic tumor response by CT or MRI of chest, abdomen, and pelvis using RECIST v1.1

Secondary Endpoints
Assess Overall survival (OS)
Up to 10 years
Assess Safety and tolerability
Up to 10 years
Assess time to second disease progression (PFS2)
Up to 10 years

Substudy 1 Arm B: MIRV Dose BEXPERIMENTALParticipants will receive dose B of MIRV with Bev, as part of the approximately 40 month study duration.
Substudy 1 Arm C: BevEXPERIMENTALParticipants will receive Bev, as part of the approximately 40 month study duration.
Substudy 2 Arm D: MIRV Dose AEXPERIMENTALParticipants will receive dose A of MIRV with carboplatin, followed by MIRV alone, as part of the approximately 31 month study duration.
Substudy 2 Arm E: MIRV Dose BEXPERIMENTALParticipants will receive dose B of MIRV with carboplatin, followed by MIRV alone, as part of the approximately 31 month study duration.
Substudy 3 Arm F: MIRV Dose AEXPERIMENTALParticipants will receive dose A of MIRV with BEV and carboplatin, followed by MIRV at a lower dose with BEV, as part of the approximately 31 month study duration.
Substudy 3 Arm G: MIRV Dose BEXPERIMENTALParticipants will receive dose B of MIRV with BEV and carboplatin, followed by MIRV at the same dose with BEV, as part of the approximately 31 month study duration.
Mirvetuximab SoravtansineEXPERIMENTALParticipants will receive MIRV 6.0 mg/kg adjusted by ideal body weight (AIBW)
Arm A: alpha receptor positive_neoadjuvant chemotherapy regimenEXPERIMENTAL* IV Carboplatin AUC 5 (Q21 days) 7 cycles (first cycle is Carbo alone, dosing for C1D1 will be provider's choice) * IV Mirvetuximab 6 mg/kg (adjusted ideal body weight) day 1 (Q21 days) 6 cycles (starting with cycle #2)
Arm B: alpha receptor negativeNO_INTERVENTIONIf a patient is found to be negative for FRα expression, they will be ineligible to receive the study treatment under the main study (Arm A). FRα negative patients will be enrolled under the biomarker-only arm (Arm B), and their treating physician can select the treatment they deem appropriate.

mirvetuximab soravtansine (MIRV; IMGN853)DRUGMirvetuximab soravtansine (also known as IMGN853 and MIRV) is an antibody-drug conjugate (ADC) that consists of a high affinity humanized monoclonal antibody against folate receptor α (FRα, the protein product of the folate receptor 1 \[FOLR1\] gene) that is conjugated to a cytotoxic maytansinoid by the hindered disulfide succinimidyl 4-(pyridin-2-yl)disulfanyl)-2-sulfo-butyrate linker (sulfo-SPDB) linker. FRα is a glycosyl-phosphatidylinositol (GPI)-linked protein, which shows limited normal tissue expression and high expression on the surface of solid tumors, particularly epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer (referenced herein collectively as EOC), endometrial cancer, non-small cell lung cancer (NSCLC), and renal cell cancer.
