NCT04606914

Brief Summary

The proposed study design is a single arm Phase II trial to document the feasibility of carboplatin-mirvetuximab - in patients with advanced-stage EOC. Patients with biopsy confirmed, newly diagnosed, advanced-stage serous EOC deemed appropriate for NACT will have their tumors evaluated for FRα receptor over-expression via a centralized immunohistochemical assay (IHC) and identified as appropriate for study participation if IHC staining is PS2+ in \>75% of cells (40% of all serous patients). Eligible patients will receive NACT with one cycle of carboplatin, followed by mirvetuximab + carboplatin (if FRα +) every 21 days for three cycles prior to interval cytoreductive surgery (iCRS). A total of 70 will be included in the study. Following completion of 4 cycles total of NACT and after allowing for appropriate recovery of cycle # 4, patients eligible for surgery, will undergo an iCRS. Patients will then complete 3 more cycles of mirvetuximab + carboplatin for a total of 7 intended cycles of treatment. It is up to the treating physician if they want to add bevacizumab to the last 2 cycles or use any type of maintenance therapy. The decision to add bevacizumab or use maintenance therapy does not need to be made upfront. Patients will sign a screening consent form prior to tissue biopsy. If a patient is found to be FRα negative, their treating physician can select the treatment they deem appropriate and the patient will be declared a screen failure. Patients with BRCA mutations are not excluded from this trial and are allowed to receive standard of care maintenance therapy including bevacizumab and/or PARP inhibitors.

Outcome Measures

Primary Outcomes (3)

  • progression free survival (PFS)

    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.

    Baseline through 2 years

  • Objective response rate (ORR)

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

    Baseline through 2 years

  • Radiographic tumor assessment per RECIST v1.1 criteria

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

    Baseline through 2 years

Secondary Outcomes (2)

  • Serum Cancer Antigen 125 (CA-125) assessments

    Baseline through 2 years

  • Safety profile of treatment with carboplatin-mirvetuximab soravtansine according to CTCAE v4.03

    Baseline through 2 years

Study Arms (2)

Arm A: alpha receptor positive_neoadjuvant chemotherapy regimen

EXPERIMENTAL

* 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)

Drug: mirvetuximab soravtansine (MIRV; IMGN853)

Arm B: alpha receptor negative

NO INTERVENTION

If 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.

Interventions

Mirvetuximab 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.
