E7777 在 Kymriah 之前用于 R/R DLBCL 的研究

在 Tisagenlecleucel (Kymriah) 治疗复发/难治性弥漫性大 B 细胞淋巴瘤 (DLBCL) 之前,使用 E7777 增强调节性 T 细胞耗竭的 I/II 期试验

This is a multicenter Phase I study to determine the maximum tolerated dose (MTD) of E7777 when given prior to cyclophosphamide/fludarabine (CY/Flu) lymphodepletion (LD) chemotherapy and an FDAapproved CAR-T product Tisagenlecleucel/Kymriah, Axicabtagene Ciloleucel/Yescarta, or lisocabtagene maraleucel/Breyanzi) for the treatment of relapsed/refractory diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma grade 3 who are at a higher risk for failure of CAR-T therapy

研究概览

详细说明

E7777 is a recombinant fusion toxin consisting of full-length human IL-2 fused to the catalytic domains of diphtheria toxin. This trial is designed to augment lymphodepletion prior to CAR-T cells by administration of a targeted immunotoxin against CD25-expressing T-cells. CD25 is expressed at high levels on Tregs but also on activated effector T cells. The use of the CAR-T cell product and associated apheresis and LD chemotherapy is considered standard of care (SOC).
