First-in-Class Drug Approved for Rare Leukemia

The Food and Drug Administration (FDA) has approved Blincyto (blinatumomab; Amgen) for the treatment of patients with relapsed or refractory Philadelphia chromosome-negative precursor B-cell acute lymphoblastic leukemia (B-cell ALL).

Blincyto is a bispecific T-cell engager (BiTE) antibody construct, a first-in-class immunotherapy for this condition. It works by engaging the body's T-cells to destroy leukemia cells. It acts as a connector between CD19, which is found on most B-cell lymphoblast surfaces, and CD3, which is found on T-cell lymphocytes.

Blincyto was granted breakthrough therapy designation, priority review, and orphan product designation. It is being approved under the FDA's accelerated approval pathway with a Risk Evaluation and Mitigation Strategy (REMS).
