The Food and Drug Administration has recently approved two autologous chimeric antigen receptor T-cell immunotherapies tisagenlecleucel (Kymriah™) and axicabtagene ciloleucel (Yescarta™) for patients with advanced lymphocytic malignancies. Both immunotherapies target the CD19-positive B-cell neoplasms. Kymriah™ is indicated for the treatment of relapsed or refractory acute lymphoblastic leukemia and large B-cell lymphoma. Yescarta™ is indicated for lymphoma only. Although the new therapy offers a promise for patients with advanced disease, it is associated with adverse events including neurotoxicity and cytokine release syndrome, which can be fatal and may require a high level of multidisciplinary supportive care. Due to the risks, both Kymriah™ and Yescarta™ are subject to Risk Evaluation and Mitigation Strategy (REMS) protocols. As active members of multidisciplinary clinical teams, pharmacists are likely to be responsible for the execution of Kymriah™ and Yescarta™ REMS programs. This manuscript describes foundational science and clinical knowledge of chimeric antigen receptor T-cell immunotherapies, common therapy-specific toxicities and REMS requirements for Kymriah™ and Yescarta™ in relation to practice of pharmacy.
