Soravtansine (DM4-SULFO-TBA), a maytansinoid derivative, is an antineoplastic agent. Antibody–maytansinoid conjugates (like Mirvetuximab soravtansine) are in clinical trials for the treatment of various cancers. Thus, Mirvetuximab soravtansine (IMGN853) is an antibody-drug conjugate (ADC) that targets FRα (folate receptor alpha) for tumor-directed delivery of the maytansinoid DM4, a potent agent that induces mitotic arrest by suppressing microtubule dynamics.
