决定异体 CAR T 细胞排斥与扩增的细胞和分子机制
Cellular and molecular mechanisms determining allogeneic CAR T cell rejection and expansion.
我们评估了11例接受单一批次cemacabtagene ansegedleucel(cema-cel)治疗的大B细胞淋巴瘤患者,cemacabtagene ansegedleucel是一种异体抗CD19 CAR T产品。
英文原题:A Phase 2 Study of WU-CART-007, an Anti-CD7 Allogeneic CAR-T Cell Therapy in T-Cell Acute Lymphoblastic Leukemia and Lymphoblastic Lymphoma (T-RRex)
这是一项 II 期注册临床试验,评估细胞治疗用于急性淋巴细胞白血病、淋巴瘤的安全性、可行性及初步疗效。当前状态:招募中。计划入组 125 例。试验地点:美国 · 杜阿尔特、洛杉矶、丹佛、华盛顿特区(共 18 个中心)。登记号:NCT06514794。
不限性别 · ≥ 6 Months
关键纳入标准: • 疾病:符合世界卫生组织(WHO)分类定义的T-ALL或T-LBL,且为复发/难治性或MRD阳性。 • 年龄≥6个月;器官功能充分。 • 筛查时东部肿瘤协作组(ECOG)体能状态为0或1,或Karnofsky体能状态评分≥70。 关键排除标准: • 既往接受过任何抗CD7治疗。 • 失代偿性溶血性贫血。 • 存在需全身免疫抑制治疗的2至4级急性或广泛型慢性移植物抗宿主病(GvHD)。无需免疫抑制治疗的1级GvHD,或仅接受局部治疗的2级皮肤GvHD可接受。
Key Inclusion Criteria: * Disease Criteria: Evidence of T-ALL or T-LBL, as defined by World Health Organization (WHO) classification, and either relapse/refractory or MRD positive * Age: Lower age limit of ≥ 6 months; adequate organ function * Eastern Cooperative Oncology Group (ECOG)/Karnofsky Performance Status 0 or 1/70 and above at Screening. Key Exclusion Criteria: * Prior treatment with any anti-CD7 therapy. * Patients with decompensated hemolytic anemia. * Presence of Grade 2 to 4 acute or extensive chronic GvHD requiring systemic immunosuppression. Grade 1 GvHD not requiring immunosuppression or Grade 2 skin GvHD if treated with topical therapy only are acceptable.

主要终点:R/R Cohort - Composite Complete Response Rate · CRc is defined as proportion of patients that achieve a complete remission (CR) + CR with incomplete hematologic recovery (CRi) · 24 months;MRD Pos Cohort - Response Rate · Defined as the efficacy of WU-CART-007 to induce complete MRD negative response · 24 months

T-RRex研究旨在评估WU-CART-007治疗复发/难治性T细胞急性淋巴细胞白血病(T-ALL)/淋巴母细胞淋巴瘤(LBL)的疗效,并评估其诱导微小残留病(MRD)阴性完全缓解的能力。
The T-RRex study evaluates the efficacy of WU-CART-007 for patients with Relapsed/Refractory (R/R) T-Cell Acute Lymphoblastic Leukemia (T-ALL)/Lymphoblastic Lymphoma (LBL) and to WU-CART-007 as a therapy to induce complete Minimum Residual Disease (MRD) negative response
