Mirvetuximab soravtansine (IMGN853) solution is an anti-folate receptor α (FRα) antibody drug-conjugate (ADC) consisting of the cytotoxic maytansinoid, DM4, covalently linked to the humanized monoclonal antibody M9346A. Mirvetuximab soravtansine selectively binds to folate receptor 1 (FOLR1). Mirvetuximab soravtansine has an anti-proliferative effect via growth arrest and augmented DNA damage.
Mirvetuximab soravtansine (IMGN853; 8 nM; 6 h; IGROV-1 cells) combined with Carboplatin promotes synergistic growth inhibitory effects and cell cycle perturbations in vitro[1].
Mirvetuximab soravtansine (IMGN853; 5 mg/kg; i.v.; female severe combined immunodeficient (SCID) mice with patient-derived xenografts) potentiates the antitumor activity of Carboplatin in vivo[1].
