Abstract
Chimeric antigen receptor (CAR) based immunotherapies offer a novel and rapidly developing technology that has great potential to ameliorate human disease. One fundamental challenge in the successful development and clinical application of CAR T-cells is the need to better understand the in vivo behaviour of adoptively infused cells. We aim to develop novel 18F-labelled PET tracers to dynamically track the persistence, migration, proliferation, and final fate of the infused CAR T-cells on a patient-by-patient basis. Thus, the new cell tracking probe would provide early insight into the safety, mechanism of action, and efficacy of CAR T-cell therapies.
