flag A new gene-edited therapy cured or put into deep remission 64% of T-ALL patients in a trial.

flag A new gene-edited therapy called BE-CAR7 has shown promising results in treating T-cell acute lymphoblastic leukaemia (T-ALL), a rare and aggressive blood cancer once considered nearly incurable. flag Developed by scientists at Great Ormond Street Hospital and University College London, the "off-the-shelf" treatment uses base-edited donor T cells to target cancer while sparing healthy tissue. flag In a trial of 11 patients—nine children and two adults—64% remained disease-free, and over 80% achieved deep remission, enabling successful stem cell transplants. flag Side effects were mild. flag The first patient, Alyssa Tapley, now 16, was treated in 2022 and is in remission, inspired to become a research scientist. flag The findings, published in the New England Journal of Medicine, mark a major advance for patients with limited treatment options.
