The European Commission (EC) has approved blinatumomab (Blincyto) for the treatment of pediatric patients with Philadelphia chromosome–negative (Ph-), CD19-positive B-cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in relapse after receiving at least 2 prior therapies or in relapse after receiving prior allogeneic hematopoietic stem cell transplantation (HSCT).1
Blinatumomab is a recombinant, single-chain monoclonal antibody that possesses antigen-recognition sites for CD3 and CD19. The CD3 complex consists of T cell surface glycoproteins, while CD19 is a tumor-associated antigen. The combination of these recognition sites into 1 therapy is thought to promote cytotoxic T lymphocyte and helper T lymphocyte activity against CD19-expressing B lymphocytes.
