    0147 Donor-derived CD7 CAR-T is effective in the treatment of refractory and relapsed T-lineage leukemia with controllable toxicity Chinese Academy of Medical Sciences Hospital of Hematology/Institute of Hematology Feng Xiaoming's team, Beijing Boren Hospital Pan Jing's team, and Shanghai Yake Biotechnology Co.
    , Ltd.
    Zhang Hongsheng's team are the first to report completely the phase I clinical data of donor-derived CD7 CAR-T in the treatment of refractory and relapsed T-ALL
    .

    This study shows that the use of donor-derived CD7 CAR-T in the treatment of T-ALL can achieve a high complete remission rate (90%), and the overall safety is controllable
