Tisagenlecleucel-T for the treatment of acute lymphocytic leukemia

ABSTRACT

Introduction: Cellular immunotherapy with autologous or allogeneic T cells, genetically engineered to express chimeric antigen receptors (CARs) or T-cell receptors, in order to redirect their cytotoxic specificity toward malignant cells, is emerging as a promising new treatment modality. The most advanced approach in clinical development is the use of anti-CD19 CAR T-cells for the treatment of CD19⁺ B-cell malignancies, including acute lymphocytic leukemia (ALL).

Areas covered: Recently, the Food and Drug Administration (FDA) approved the first anti-CD19 CAR T-cell product, tisagenlecleucel, for the treatment of pediatric and young adult patients with relapsed/refractory ALL. In this overview, we described the advances in the field, including a summary of clinical trials with tisagenlecleucel in ALL published to date.

Expert opinion: CAR T-cell therapy has been developed in the context of small clinical studies and very few centers have had to deal with the challenges of managing CAR T-cells administration. However, this approach is likely to become a standard option for patients with relapsed/refractory B-cell lineage ALL.
