研究概要

在 CAR-T 治疗后复发时,早期使用 epcoritamab 且不联合细胞毒性药物,可恢复 CAR-T 细胞数量和细胞毒性,这可能潜在带来有利的临床结局。

研究思路结论见上方概要

双特异性抗体对复发/难治性B细胞淋巴瘤患者有效,即使在CAR-T 治疗后也是如此。

在CAR-T 治疗后复发的B细胞淋巴瘤患者中,于epcoritamab输注前后进行了外周血CAR-T 动力学及体内功能分析。

CAR拷贝数在复发时激增,并在epcoritamab给药后再次上升。CAR-T 耗竭标志物的表达水平未增加,而穿孔素和颗粒酶B的表达在epcoritamab诱导后增加。

Bispecific antibodies are effective for relapsed/refractory B-cell lymphoma patients even after CAR-T therapy.

Peripheral blood CAR-T kinetics and functional analysis in vivo were carried out pre- and post-epcoritamab infusion in B-cell lymphoma patients relapsing after CAR-T therapy.

CAR copy numbers spiked at relapse and rose again following epcoritamab administration. Expression levels of CAR-T exhaustion markers did not increase, whereas perforin and granzyme B expression increased after epcoritamab induction.

Early epcoritamab administration without cytotoxic agents at relapse after CAR-T therapy revives CAR-T cell numbers and cytotoxicity, which may potentially lead to favorable clinical outcomes.
