CD19-targeted CAR T cells, such as tisagenlecleucel, have demonstrated high rates of complete remission and long-lasting responses in clinical trials...Despite these innovations, further research is needed to refine manufacturing processes, reduce costs, and improve long-term outcomes. This review emphasizes the transformative potential of CAR-T therapy for pediatric B-ALL and discusses critical challenges and future directions in the field.

In apheresis, a cut-off value of >4.3% of CD8+ TCM predicted strong CAR-T expansion (AUC: 0.80; p = 0.023) and superior progression-free survival (p = 0.04) compared with patients who had CD8+ TCM below the cut-off. Our data suggest that high frequencies of CD8+ TCM cells in apheresis samples may represent a promising pre-treatment biomarker associated with strong CAR-T expansion and superior clinical outcome in r/r LBCL patients following axi-cel.
By contrast, CARpos T cells obtained from infusion products in long-term responders are enriched in the CD38-CD73-Tim-3-HLA-DR+ phenotype, characterized by a decreased ability to produce adenosine, memory-like transcriptomic characteristics, and leveraging of mitochondrial metabolism and oxidative phosphorylation. Our study reveals that the CD38-CD73-Tim-3-HLA-DR+ phenotype contributes to long-term remission in patients with BCP-ALL who receive tisagenlecleucel.
