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:Determining the Mechanisms of Loss of CAR T Cell Persistence
这是一项分期未标注的注册临床试验,评估细胞治疗用于急性淋巴细胞白血病的安全性、可行性及初步疗效。当前状态:招募中。计划入组 50 例。试验地点:欧洲 · 伦敦、曼彻斯特(共 3 个中心)。登记号:NCT05809284。
不限性别 · ≤ 25 Years
纳入标准: 1. 年龄不超过25岁的儿童和年轻成人,患复发/难治性急性淋巴细胞白血病(ALL),计划接受已获批的CD19靶向CAR-T细胞治疗(Tisagenlecleucel)。 2. 已签署书面知情同意书。 排除标准: 1. 正在临床试验中接受其他CD19靶向CAR-T细胞产品治疗。 2. 研究者认为可能导致患者无法遵守研究方案的任何情况。
Inclusion Criteria: 1. Children and young adults (age 25 years or younger) with relapsed/refractory ALL who are planned to receive licensed CD19-targeted CAR-T cell treatment (Tisagenlecleucel) 2. Written informed consent Exclusion Criteria: 1. Patients receiving an alternate CD19-directed CAR T-cell product on a clinical trial 2. Any reason that in the opinion of the investigator, patients won't be able to adhere to the protocol
以上为辅助阅读译文。是否适合入组须由主治医生判断,最终以登记平台与研究者确认为准。
主要终点:Time to circulating CAR-T cell loss · CAR-T persistence will be measured in the central lab from blood samples. · Through study completion, until the last patient reaches 1 year post-infusion
本前瞻性观察性研究纳入接受CD19嵌合抗原受体T细胞(CAR-T细胞)治疗的儿童及年轻成人急性淋巴细胞白血病(ALL)患者。研究将考察CAR-T细胞持续存在情况随时间的变化及其影响因素。
A prospective observational study of pediatric and young adult acute lymphoblastic leukaemia (ALL) patients treated with CD19 chimeric antigen receptor T-cells (CAR-T cells). The study will examine changes in CAR-T persistence over time and causal factors.
