Clinical Trial Summary

This Phase 3 study is designed to compare the efficacy and safety of mirvetuximab soravtansine vs. investigator's choice chemotherapy in patients with platinum-resistant high-grade epithelial ovarian cancer, primary peritoneal, or fallopian tube cancer, whose tumors express a high-level of FRα. Patients will be, in the opinion of the Investigator, appropriate for single-agent therapy for their next line of therapy. Folate receptor alpha (FRα) positivity will be defined by the Ventana FOLR1 (FOLR1-2.1) CDx assay.

Description:

Patients will be randomized to either mirvetuximab soravtansine (MIRV) or Investigator's Choice chemotherapy (paclitaxel, PEGylated liposomal doxorubicin, or topotecan).

Intervention

Drug:
• Mirvetuximab Soravtansine
Mirvetuximab soravtansine is an antibody drug conjugate designed to target folate receptor a (FRa). It consists of the humanized anti-FRa mAb M9346A attached via a cleavable disulfide linker to the cytotoxic maytansinoid, DM4.
• Paclitaxel
Paclitaxel is a taxane that can stabilize microtubules to inhibit cell division. It was approved for treatment of recurrent epithelial ovarian cancer.
• Topotecan
Topotecan induces irreversible DNA damage. It inhibits topoisomerase 1, leading to both single and double strand DNA break that eventually promote apoptosis. Topotecan was approved for treatment of epithelial ovarian cancer after failure of initial or subsequent chemotherapy.
• Pegylated liposomal doxorubicin
Pegylated liposomal doxorubicin is a standard chemotherapy regimen used for treating platinum-resistant ovarian cancer. The active component doxorubicin is an anthracycline that intercalates DNA, leading to inhibition of replication and subsequently, the inhibition of proper cell division.
