A Multicenter Clinical Study on the Safety and Efficacy of CAR-T in the Treatment of Relapsed / Refractory Non Hodgkin's Lymphoma

Not Applicable

Recruiting

• Conditions: Non-hodgkin's Lymphoma
• Interventions: Biological: Auto CAR-T; Drug: Cyclophosphamide,Fludarabine; Procedure: Leukapheresis

• Registration Number: NCT04666168
• Lead Sponsor: Hebei Senlang Biotechnology Inc., Ltd.

Brief Summary

This study is a multicenter, non randomized, single arm, open clinical trial. The selected disease was relapsed / refractory NHL, and the disease was classified into highly aggressive lymphoma, invasive lymphoma and inert lymphoma; Highly invasive NHL included Burkitt lymphoma (BL), lymphoblastic lymphoma (LBL), high-grade B-cell lymphoma, etc; Invasive NHL includes diffuse large B-cell lymphoma, mantle cell lymphoma and peripheral T-cell lymphoma; Inert NHL contains follicular lymphoma, small lymphocytic lymphoma and marginal zone lymphoma.

Detailed Description

A single car consists of scFv, hinge region, transmembrane region, costimulatory domain and zeta subunit of CD3.Prior to CAR-T cell infusion, the patients will be subjected to preconditioning treatment. After CAR-T cell infusion, the patients will be evaluated for adverse reactions and efficacy.
