The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

mirvetuximab soravtansine. An immunoconjugate consisting of the humanized monoclonal antibody M9346A against folate receptor 1 (FOLR1) conjugated, via the disulfide-containing cleavable linker sulfo-SPDB, to the cytotoxic maytansinoid DM4, with potential antineoplastic activity. The anti-FOLR1 monoclonal antibody moiety of mirvetuximab soravtansine targets and binds to the cell surface antigen FOLR1. After antibody-antigen interaction and internalization, the immunoconjugate releases DM4, which binds to tubulin and disrupts microtubule assembly/disassembly dynamics, thereby inhibiting cell division and cell growth of FOLR1-expressing tumor cells. FOLR1, a member of the folate receptor family is overexpressed on a variety of epithelial-derived cancer cells. The sulfo-SPDB linker prevents cleavage in the bloodstream and may improve this agent's efficacy in multidrug resistant tumor cells. NCI Drug Dictionary

boron-dipyrromethene-modified olaparib fluorescent imaging agent. A poly (ADP-ribose) polymerase type 1 (PARP1) fluorescence imaging agent based on the PARP1 inhibitor olaparib, in which the cyclopropane group of olaparib is replaced by the green fluorescent dye boron-dipyrromethene (BODIPY) fluorophore (FL), with potential fluorescent imaging activity. Upon administration of the fluorescent PARP1 inhibitor PARPi-FL, the olaparib binding moiety specifically targets and binds to PARP1, which is often overexpressed on cancer cells. Upon fluorescent imaging, the PARP1-expressing cancer cells can be visualized. PARP1, the nuclear enzyme that catalyzes post-translational ADP-ribosylation of nuclear proteins, is activated by single-strand (SS) DNA breaks and overexpressed in certain tumor cells; it plays a key role in DNA repair, tumor cell resistance and survival. NCI Drug Dictionary

Treatments listed in the registry

  • Mirvetuximab Soravtansine-gynx (Drug): 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 (Drug): 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.

Non Randomized · Sequential · masking: None

Safety Lead In (Experimental)

Treatment (Experimental)

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.
