CD19 Chimeric Antigen Receptor Therapy for Refractory Aggressive B-Cell Lymphoma.

Jacobson CA¹.

Abstract

PURPOSE:

Anti-CD19-directed chimeric antigen receptor (CAR) T-cell therapy has had a resounding effect on the treatment of chemotherapy-insensitive aggressive B-cell non-Hodgkin lymphoma (B-NHL). There are now two US Food and Drug Administration (FDA)-approved products available for treating these patients, and a third product is expected to be approved in the coming months. The question remains: Is there a preferred or best product for my patient? However, answering that question is more complicated than simply balancing the reported efficacy and toxicity results.

DESIGN:

This review outlines potential confounding factors involving the three products and their pivotal clinical trials and highlights additional considerations of manufacturing reliability and overall cost that must be considered when weighing one product against another. It will also review the directions in which the field is moving and strategies being examined to improve efficacy as well as toxicity.

CONCLUSION:

Because a randomized three-arm clinical trial is unlikely, a product may have to be chosen on the basis of results from treatment centers that have experience with all three products. But by the time those results are available, they are likely to be outdated because, given the rapid evolution of the field, the next product will probably have been identified.
