Determining the Mechanisms of Loss of CAR T Cell Persistence (CARPERS)

August 6, 2026 updated by: University College, London
A prospective observational study of pediatric and young adult acute lymphoblastic leukaemia (ALL) patients treated with CD19 chimeric antigen receptor T-cells (CAR-T cells). The study will examine changes in CAR-T persistence over time and causal factors.
