Mirvetuximab soravtansine (ImmunoGen) is a folate receptor alpha (FRa)-targeted antibody-drug conjugate (ADC) in development for advanced ovarian cancer patients that overexpress FRa. It is comprised of an FRa-targeted monoclonal antibody linked to the cytotoxic effector compound maytansinoid DM4. As an ADC, the FRa-targeted antibody ensures tumor-directed delivery of maytansinoid DM4, which induces mitotic arrest by suppressing microtubule dynamics. Folate receptors have limited distribution in normal tissues, but FRa overexpression is characteristic of several tumor types including ovarian, breast, brain, lung, and colorectal cancer. FRa is overexpressed in approximately 70% of primary ovarian tumors and over 80% of recurrent tumors.
As the only drug directly targeting the FRa-positive (FRa+) patient population, mirvetuximab soravtansine could become a standard choice in this setting. Early-phase data indicate the drug is active and tolerable in FRa+ platinum-resistant ovarian cancer patients as a monotherapy. The Phase III FORWARD I trial has been initiated to confirm these results and will better determine the drug’s place in the ovarian cancer treatment paradigm.
