Drug Information available for: Olaparib

Arm Intervention/treatment
Experimental: Safety Lead In Drug: Mirvetuximab Soravtansine
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).
Other Names:
  • IMGN853
  • MIRV

Drug: 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.

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.

Primary Outcome Measures :
  1. 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 ]
    PFS will be defined as the time from first dose of MIRV and Olaparib until investigator-assessed radiologic PD or death, whichever occurs first


Secondary Outcome Measures :
  1. To evaluate safety and tolerability of MIRV combined with Olaparib by Adverse Events as measured by CTCAE v 5.0 [ Time Frame: Through study completion, average of 12 months ]
    The team will use treatment-emergent adverse events (TEAEs) and laboratory test results, physical examination, or vital signs to determine AEs as described by CTCAE v5.0

  2. Determine Overall Response Rate [ Time Frame: Through study completion, average of 12 months ]
    Defined by confirmed best response of CR or PR as assessed by the investigator

  3. Determine Duration of Response [ Time Frame: Through study completion, average of 12 months ]
    Defined as the time from initial investigator-assessed response (CR or PR) until progressive disease (PD) as assessed by the investigator

  4. Determine Overall Survival [ Time Frame: Up to 5 years ]
    Defined as the time from first dose of MIRV and Olaparib until death
