Details and patient eligibility


Objective: To evaluate the safety and tolerability of hNeo-T injection in patients with relapsed or refractory EBV-positive T-cell lymphoma. Secondary objective: To evaluate the effectiveness of hNeo-T injection, and to evaluate the objective response rate (ORR) and disease control rate (DCR) by Lugano2014 criteria; Progression-free survival (PFS), duration of response (DOR), and overall survival (OS ) followed. Objective of the exploratory study: To investigate the in vivo process of hNeo-T injection and describe the activity and related biological functions of hNeo-T cells in vivo, including but not limited to.

Full description

This is a single arm,open label and non-randomized clinical trial with a planned enrollment of 6-12 participants to evaluate the safety and tolerability of hNeo-T injection, determine dose-limiting toxicity (DLT), explore the maximum tolerated dose (MTD), or the recommended dosage for later clinical studies. The DLT observation period is 28 days after the infusion of hNeo-T injection. In the first stage, 3 subjects will be enrolled in the experiment of the first dose group (total number of cells is 5×10^7/ bag). If DLT does not appear during the experiment, the study will enter the second stage after safety assessment and analysis, and 3 subjects will be enrolled in the experiment of the second dose group (total number of cells is 1×10^8/ bag) in this stage. If DLT occurs in one of the 3 subjects , three more subjects will be added to the dose group. If no additional DLT occurs, the study will enter the next dose group; If additional DLT occurs, enrollment in the group will be stopped and the dose will be defined as an intolerable dose; If DLT occurs in two or more of the 3 subjects, enrollment in the dose group will be discontinued and the dose will be defined as an intolerable dose; After climbing to an intolerable dose, there will be a discussion to decide whether to explore an intermediate dose or to define the dose level as MTD; If MTD is not defined in the high-dose group, the high-dose group will be used as the final climbing dose. If a higher dose will be planned, a follow-up clinical study can only be carried out after evaluation,discussion and consensus.
