Balancing the CAR T: perspectives on efficacy and safety of CAR T-cell therapy in hematologic malignancies.

Chimeric antigen receptor (CAR) T-cell therapy is an example of how immunotherapy is revolutionizing the treatment of hematologic malignancies with unprecedented response rates in patients with relapsed/refractory lymphoma, multiple myeloma, and acute lymphoblastic leukemia. The process for administering CAR T-cell therapy is complex, with multiple steps including CAR T-cell manufacturing, lymphodepleting chemotherapy, cellular therapy infusion, and management of short-term and long-term toxicities. While effective, broad use of CAR T-cell therapies is limited by potential for life-threatening toxicities, challenges related to manufacturing a patient-specific product, high costs and inadequate reimbursement, and incomplete or unsustained disease response. Pharmacists are intricately involved in the process of providing CAR T-cell therapy both at the organizational level of budgeting and coordinating therapy and in direct patient care roles providing counseling and support for adverse effect management. Research in CAR T-cell therapy is expected to improve tolerability and expand indications to more types of malignancies and earlier phases of disease. Managed care professionals should have an understanding of the clinical trial data and place in therapy in lymphoma, myeloma, and acute lymphoblastic leukemia as well as guideline recommendations for adverse effect management associated with CAR T-cell therapies.
