Chimeric antigen receptor (CAR) T therapies for the treatment of hematologic malignancies: clinical perspective and significance

Michael M Boyiadzis et al. J Immunother Cancer. .

Abstract

Chimeric Antigen Receptor (CAR) T cell therapies - adoptive T cell therapies that have been genetically engineered for a new antigen-specificity - have displayed significant success in treating patients with hematologic malignancies, leading to three recent US Food and Drug Administration approvals. Based on the promise generated from these successes, the field is rapidly evolving to include new disease indications and CAR designs, while simultaneously reviewing and optimizing toxicity and management protocols. As such, this review provides expert perspective on the significance and clinical considerations of CAR T cell therapies in order to provide timely information to clinicians about this revolutionary new therapeutic class.

Keywords: Axicabtagene ciloleucel; Chimeric antigen receptor; Leukemia; Lymphoma; Tisagenlecleucel.

Chimeric Antigen Receptor (CAR) design across generations. First generation Chimeric Antigen Receptors (CARs) include an extracellular antigen-binding domain and an intracellular T cell activation domain, commonly CD3ζ or FcεRIγ. Second generation CARs built upon first generation constructs by including an intracellular costimulatory domain, commonly 4-1BB or CD28, incorporated into the FDA approved CAR T therapies tisagenlecleucel and axicabtagene ciloleucel, respectively. Costimulatory domains help enhance CAR T cell cytotoxicity and proliferation compared to first generation designs. Third generation CARs include multiple costimulatory domains, primarily to increase CAR T cell proliferation and persistence
