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