登记简述

这项I期试验研究CD-19导向的嵌合抗原受体(CAR)-T细胞疗法对复发(recurrent)或对治疗无反应(refractory)的B细胞恶性肿瘤患者的治疗效果。CD-19 CAR-T细胞利用患者自身的一些免疫细胞,称为T细胞,来杀死癌症。T细胞对抗感染,在某些情况下也能杀死癌细胞。从血液中取出一些T细胞,然后在实验室中,研究人员将一个新基因插入T细胞。这个基因使T细胞能够识别并可能治疗癌症。新的修饰T细胞被称为IC19/1563治疗。IC19/1563可能有助于治疗复发/难治性B细胞恶性肿瘤患者。

核对登记原文(英文)

This phase I trial studies the effects of CD-19 directed chimeric antigen receptor (CAR)-T cell therapy for the treatment of patients with B cell malignancies that have come back (recurrent) or have not responded to treatment (refractory). CD-19 CAR-T cells use some of a patient's own immune cells, called T cells, to kill cancer. T cells fight infections and, in some cases, can also kill cancer cells. Some T cells are removed from the blood, and then laboratory, researchers will put a new gene into the T cells. This gene allows the T cells to recognize and possibly treat cancer. The new modified T cells are called the IC19/1563 treatment. IC19/1563 may help treat patients with relapsed/refractory B cell malignancies.
