Chimeric antigen receptor (CAR) T-cell therapy is an investigational immunocellular therapy that reprograms a patient's cytotoxic T cells to engage and eliminate malignant cells. CAR T-cell therapies targeting the CD19 antigen have demonstrated high efficacy in clinical trials for patients with B-cell malignancies and may potentially be available on a broader scale in the future. CAR T-cell therapy begins with the collection of a sufficient number of T cells from a patient's peripheral blood through leukapheresis. Several factors must be considered when patients undergo leukapheresis for CAR T-cell therapy, including age and prior therapies. The leukapheresis material is shipped to a manufacturing facility, followed by return of the CAR T cells to the treatment center. Careful coordination of a multidisciplinary team composed of physicians, nurses, pharmacists and other hospital personnel is critical for the proper care of the patient before, during and after CAR T-cell therapy. CAR T-cell therapy has been associated with adverse events (AEs) such as cytokine release syndrome, which requires rapid attention by the emergency department, intensive care unit and hospital pharmacy. In this review, we discuss several aspects of institutional preparation for leukapheresis, CAR T-cell infusion and AE management based on our experience with clinical trials of the CD19 CAR T-cell therapy CTL019.
