Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single arm study to evaluate the efficacy and safety of Sequential CD19 and CD22 targeted CAR-T cells therapy for patients with relapsed/refractory B Cell Lymphoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Although the CD19 targeted CAR-T cell therapies have gained significant results in patients with relapsed and refractory B-cell Leukemia and Lymphoma. There are some patients who resisted anti-CD19 CAR-T cells or get CD19 negative relapse. To make further improvement, We launch such a clinical trial using sequential CD19 and CD22 targeted CAR-T cells for patients with relapsed and refractory B Cell Lymphoma to evaluate the efficacy and safety of sequential CD19 and CD22 targeted CAR-T cell therapy.

sequential CD19 and CD22 targeted CAR-T cells treat

Group Type EXPERIMENTAL

CD19 and CD22 targeted CAR-T cells

Intervention Type BIOLOGICAL

CAR-T cells were manufactured from peripheral blood mononuclear cells collected by leukapheresis and frozen for multiple uses. Before each CAR T-cell infusion (day 0), patients received lymphodepleting chemotherapy composing of Fludarabine (30 mg/m2/day) and Cyclophosphamide (300 mg/m2/day) on days -5 to -3. No bridging chemotherapy was given between enrollment and infusion. In sequential CAR-T clinical trials, CAR-T cells will be given.(anti-CD19 CAR-T first, then anti-CD22 CAR-T).
