Interventions and Outcome Measures

Arms

experimental: Safety Lead In

experimental: Treatment

All patients will receive MIRV at 5mg/kg AIBW administered through IV infusion on Day 1 of every 3-week cycle (Q3W).

All patients will receive Olaparib at 300mg taken orally twice daily with or without food. Dosage and administration will follow current single-agent Olaparib package insert dosage and administration guidelines.

Patients will continue to receive MIRV and Olaparib until PD, unacceptable toxicity, withdrawal of consent, or death, whichever comes first. If toxicity deems the patient to discontinue one drug, the patient may continue the other drug until PD, unacceptable toxicity, withdrawal of consent, or death, whichever comes first.

Interventions

Mirvetuximab Soravtansine-gynx

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-(pyridine-2-yl)disulfanyl)-2-sulfo-butyrate linker (sulfo-SPDB).

Olaparib

Olaparib is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP1, PARP2, and PARP3. PARP enzymes are involved in normal cellular functions, such as DNA transcription and DNA repair.

Primary outcome measure

  • To measure progression free survival (PFS) with the use of MIRV combined with Olaparib in women with recurrent platinum sensitive ovarian, peritoneal, and fallopian tube cancer. [ Time Frame: Through study completion, average of 12 months ]
