主要终点:Progression free survival (PFS) after administration of the ATLCAR.CD30 in subjects with relapsed/refractory CD30+ peripheral T cell lymphoma · PFS is defined from day of initial lymphodepletion administration of the first ATLCAR.CD30 product infusion to the date of disease progression per the Revised Lugano Criteria or death as a result of any cause. Subjects who do not meet criteria for progression by the analysis data cut-off date will be censored at their last evaluable disease assessment date. · 8 weeks
次要终点:Best overall response rate (BOR) mediated by the ATLCAR.CD30 product administered in subjects with relapsed/refractory CD30+ peripheral T cell lymphoma;Objective response rate (ORR) mediated by the first infusion of the ATLCAR.CD30 product administered in patients with relapsed/refractory CD30+ peripheral T cell lymphoma.;Responses improved by the second infusion of the ATLCAR.CD30 product administered in subjects with either partial response or stable disease following the first infusion of ATLCAR.CD30;Incidence of Dose Limiting Toxicity (DLT) (safety and tolerability) when administering two sequential infusions of the ATLCAR.CD30 product in subjects with relapsed/refractory CD30+ peripheral T cell lymphoma;Overall survival (OS) after administration of the ATLCAR.CD30 administered to subjects with relapsed/refractory CD30+ peripheral T cell lymphoma;Comparison of the expansion and persistence of ATLCAR.CD30 in peripheral blood when infused after a single infusion of ATLCAR.CD30 cells and after two infusions with ATLCAR.CD30 cells
由 ATLCAR.CD30 细胞组成的细胞产品将通过外周静脉或中心静脉通路,经静脉注射在 5 - 10 分钟内给药。输注体积取决于细胞冻存时的浓度以及受试者的体型。符合条件的受试者将在完成淋巴细胞清除化疗方案后 2 - 14 天内接受给药
这是一项研究,旨在确定ATLCAR.CD30治疗复发/难治性外周T细胞淋巴瘤的安全性和耐受性。将从研究参与者中采集血样,并分离免疫T细胞。T细胞将在UNC-Chapel Hill的实验室中进行基因修饰,使其能够产生CD30抗体。这些经过修饰的T细胞,称为ATLCAR.CD30,将能够靶向并附着于携带CD30抗原的淋巴瘤癌细胞。一旦附着,期望这些T细胞能够攻击并摧毁淋巴瘤癌细胞。为了使身体为ATLCAR.CD30细胞做好准备,参与者将使用两种化疗药物完成淋巴细胞清除。淋巴细胞清除将在ATLCAR.CD30输注前进行三天。如果参与者对这项治疗有反应,并且有足够的未使用ATLCAR.CD30细胞,他们可能有资格接受第二次输注。第二次输注将在第二次淋巴细胞清除化疗后给予。本研究中的大多数门诊访视将持续1-8小时。 参与这项研究存在相关风险。治疗风险包括感染、发热、恶心、呕吐、神经毒性以及细胞因子释放综合征,后者可能包括低血压或呼吸困难。其他风险与研究程序相关,例如活检、影像学检查、输注和违反保密性。
This is a research study to determine the safety and tolerability of ATLCAR.CD30 for treating relapsed/refractory Peripheral T Cell Lymphoma. Blood samples will be collected from study participants and the immune T cells will be separated. T cells will be genetically modified in a laboratory at UNC-Chapel Hill to enable them to produce CD30 antibody. The modified T cells, called ATLCAR.CD30, will be able to target and attach to lymphoma cancer cells that carry the CD30 antigen. Once they are attached, the hope is that the T cells will attack and destroy the lymphoma cancer cells. To prepare the body for the ATLCAR.CD30 cells, participants will complete lymphodepletion with two chemotherapy agents. Lymphodepletion will happen over three days prior to ATLCAR.CD30 infusion. If participants respond to this treatment, and there are sufficient unused ATLCAR.CD 30 cells, they may be eligible to receive a second infusion. The second infusion will be given after a second lymphodepletion chemotherapy. Most of the clinic visits in this research will last between 1-8 hours. There are risks associated in participating in this research study. Risks of treatment include infection, fever, nausea, vomiting, neurotoxicity, and cytokine release syndrome which can include low blood pressure or difficulty breathing. Other risks are associated with study procedures, such as biopsies, imaging, infusion, and breach of confidentiality.
