Besponsa a New Treatment Option for Patients with Relapsed/Refractory B-Cell ALL

On August 17, 2017, the FDA approved inotuzumab ozogamicin (Besponsa), a targeted therapy, for the treatment of adults with relapsed or refractory B-cell acute lymphoblastic leukemia (ALL). The drug blocks cancer growth by binding to B-cell ALL cells that express CD22. The FDA designated inotuzu_mab ozogamicin as an orphan drug and applied its priority review for this approval.
