登记简述

这项I期试验测试了脑室内(ICV)注射CD19嵌合抗原受体(CAR)T细胞治疗中枢神经系统(CNS)淋巴瘤患者的安全性、副作用和最佳剂量。CAR-T 细胞疗法是一种治疗方法,其中患者的T细胞(一种免疫系统细胞)在实验室中被改变,以便它们能够攻击癌细胞。T细胞从患者的血液中提取。然后,在实验室中,将一种能与患者癌细胞上特定蛋白质CD19结合的特殊受体的基因添加到T细胞中。这种特殊受体被称为嵌合抗原受体(CAR)。大量CAR-T 细胞在实验室中培养,并通过输注给予患者以治疗某些癌症。ICV是一种注射技术,通过手术放置的导管,将CD19-CAR-T 细胞直接输送到大脑中的脑脊液(脑脊液在脑和脊髓的中空空间以及覆盖和保护脑和脊髓的薄层组织中流动)中。通过ICV给予CD19-CAR-T 细胞可能比其他方法更有效地治疗CNS淋巴瘤患者。

This phase I trial tests the safety, side effects, and best dose of intracerebroventricularly (ICV) administered CD19-chimeric antigen receptor (CAR) T cells in treating patients with central nervous system (CNS) lymphoma. CAR T cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein, CD19, on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. ICV is an injection technique that delivers the CD19-CAR T cells directly into the cerebrospinal fluid (which flows in and around the hollow spaces of the brain and spinal cord, and the thin layers of tissue that cover and protect the brain and spinal cord) in the brain, through a surgically placed catheter. Giving CD19-CAR T cells ICV may be more effective at treating patients with CNS lymphoma than giving them via other methods.
