Biobehavioral Implications of Chimeric Antigen Receptor T-cell Therapy: Current State and Future Directions

Abstract

Chimeric antigen receptor (CAR) T-cell therapy has demonstrated remarkable clinical responses in hematologic malignancies. Recent advances in CAR T-cell therapy have expanded its application into other populations including older patients and those with central nervous system and solid tumors. Although its clinical efficacy has been excellent for some malignancies, CAR T-cell therapy is associated with severe and even life-threatening immune-mediated toxicities, including cytokine release syndrome and neurotoxicity. There is a strong body of scientific evidence highlighting the connection between immune activation and neurocognitive and psychological phenomena. To date, there has been limited investigation into this relationship in the context of immunotherapy. In this review, we present a biobehavioral framework to inform current and future cellular therapy research and contribute to improving the multidimensional outcomes of patients receiving CAR T-cell therapy.
