PHASE I SAFETY/FEASIBILITY: GENETICALLY MODIFIED AUTOLOGOUS T CELLS IN LYMPHOMA

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目及 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 复发的B细胞淋巴瘤是无法治愈的常规疗法，除了干细胞移植，毒性治疗方式，挽救只有20-50%的患者复发的疾病。 因此，显然需要创新的新治疗方法。 这项I期研究将评估使用基因疗法治疗复发性或难治性套细胞或惰性非霍奇金淋巴瘤患者的可行性、安全性、毒性和疗效。 这项临床试验使用基因修饰的免疫细胞，试图提高人体的免疫系统，以打击淋巴瘤。 免疫细胞将通过白细胞分离术从患者体内取出，然后在实验室中进行遗传修饰和扩增，然后分三次输注给患者。 将有12人参加这项研究。 前三名参与者仅接受免疫细胞输注，其余的人将接受相同的治疗，加上药物白细胞介素2（IL-2）来刺激免疫细胞生长。 在一些患者中，第二或第三剂量的细胞可能会被铟-111标记，以评估体内运输。该研究将检查这种方法的安全性和毒性，患者的淋巴瘤如何对遗传修饰的免疫细胞做出反应，这些细胞在体内停留多久，细胞在体内的位置，以及身体是否对这些细胞产生免疫反应。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Relapsed B cell lymphomas are incurable with conventional therapies except stem cell transplantation, a toxic treatment modality which salvages only 20-50% of patients with recurrent disease. Innovative new treatment approaches are therefore clearly necessary. This phase I study will evaluate the feasibility, safety, toxicity, and efficacy of using gene therapy to treat patients with relapsed or refractory mantle cell or indolent non-Hodgkin's lymphomas. This clinical trial uses genetically modified immune cells to try to improve the body's immune system to fight lymphoma. Immune cells will be taken from the patient's body through leukapheresis, and then genetically modified and expanded to large numbers in a laboratory before being reinfused to the patient in three doses. Twelve people will take part in the study. The first three people who take part received immune cell infusions alone, and the remainder will receive the same treatment, plus the drug interleukin 2 (IL-2) to stimulate the immune cells to grow. In some patients, the second or third dose of cells may be labeled with Indium-111 for assessment of in vivo trafficking The study will examine the safety and toxicity of this approach, how a patient's lymphoma responds to the genetically modified immune cells, how long these cells remain in the body, where the cells travel in the body, and whether the body develops an immune response to these cells.
