研究目的:

主要目的:评价CD19XCD22 CAR-T治疗复发/难治B细胞肿瘤的安全性。 次要目的:1.探索CD19XCD22 CAR-T治疗复发/难治B细胞肿瘤的有效范围; 2.评价CD19XCD22 CAR-T在体内的扩增、持续性。  

Objectives of Study:

Primary objective: Safety of αCD19XCD22 bispecific CAR-T cells (CT120A) in patients with relapsed/refractory B cell malignancies. Secondary objective: 1. Efficacy of CT120A cells to treat relapsed/refractory B-cell malignancies; 2. Expansion and persistence of CT120A cells in patients with relapsed/refractory B-cell malignancies.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

Patients with BCL and B-ALL will receive CT120A cells at 1-3×10^6 CAR+ T cells/kg and 0.5-2×10^6 CAR+ T cells/kg respectively, given as a single infusion. Three dose levels of 1, 2 and 3×10^6 CAR+ T cells/kg will be assessed in BCL whilst 0.5, 1 and 2×10^6 CAR+ T cells/kg in B-ALL. Dose-escalation will be designed to determine the maximum tolerated dose (MTD) based on the occurrence of dose-limiting toxicity (DLT) within 14 days after the infusion of CT120A cells. Blood tests, biopsies, imaging and physical examination will be performed to evaluate safety, efficacy and persistence of CT120A at regular intervals. Subjects will undergo leukapheresis to isolate peripheral blood mononuclear cells (PBMCs) to manufacture CT120A cells, during which cyclophosphamide and fludarabine will be administered for the purpose of lymphocytes depletion. After lymphodepletion, subjects will receive one dose treatment with CT120A cells by intravenous (IV) infusion. The initial dose of 1×10^6 CAR+ T cells/kg and 0.5×10^6 CAR+ T cells/kg will be infused for BCL and B-ALL respectively on day 0.
