Summary
Brief summary (as posted)
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.

- Arm B: alpha receptor negative
- description
- 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.
