登记简述

这项I期试验研究在干细胞移植后,将巨细胞病毒(CMV)特异性CD19-嵌合抗原受体(CAR)T细胞与CMV修饰的安卡拉痘苗(MVA)三联疫苗联合用于治疗高级别B细胞非霍奇金淋巴瘤患者的安全性和副作用。CAR T细胞是一种治疗方法,即在实验室中改变患者的T细胞(一种免疫系统细胞),使其能够攻击癌细胞。T细胞取自患者的血液。然后,在实验室中加入一种特殊受体的基因,该受体能与患者癌细胞上的某种蛋白质结合。这种特殊受体称为嵌合抗原受体(CAR)。大量CAR T细胞在实验室中培养,并通过输注给予患者。诸如CMV-MVA三联疫苗之类的疫苗由基因修饰病毒制成,可能有助于身体建立有效的免疫反应以杀死癌细胞。在干细胞移植后给予CMV特异性CD19-CAR T细胞加CMV-MVA三联疫苗可能有助于防止癌症复发。

This phase I trial studies the safety and side effects of cytomegalovirus (CMV) specific CD19-chimeric antigen receptor (CAR) T-cells along with the CMV-modified vaccinia Ankara (MVA) triplex vaccine following a stem cell transplant in treating patients with high grade B-cell non-Hodgkin lymphoma. CAR T-cells are 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 on the patient's cancer cells is added 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. Vaccines such as CMV-MVA triplex are made from gene-modified viruses and may help the body build an effective immune response to kill cancer cells. Giving CMV-specific CD19-CAR T-cells plus the CMV-MVA triplex vaccine following a stem cell transplant may help prevent the cancer from coming back.
