供者来源和现货型异基因抗 CD19 CAR-T 细胞疗法用于复发/难治性急性淋巴细胞白血病和非霍奇金淋巴瘤：系统综述与荟萃分析

Allogeneic anti-CD19 chimeric antigen receptor (CAR) T-cell therapy has the potential for extensive clinical applications.

This study aimed to evaluate its efficacy and safety in treating relapsed or refractory (R/R) acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL). Four databases were searched for relevant studies. Among patients treated with donor-derived CAR T-cell therapy, ALL patients had a complete remission (CR) rate of 80 % and a 1-year overall survival rate of 51 %. The graft-versus-host disease (GvHD) rate was 4 %, cytokine release syndrome was 69 %, and immune effector cell-associated neurotoxicity syndrome was 8 %.

For off-the-shelf CAR T-cell therapy, the CR rate for ALL was 70 %, and for NHL, it was 52 %. The objective response rate for NHL was 72 %. The pooled GvHD of off-the-shelf CAR T-cell therapy for ALL and NHL combined was 0 %. Allogeneic anti-CD19 CAR T-cell therapy are effective and safe for treating R/R ALL and NHL.
