About this study

This is an open-label, single-arm, phase I clinical trial with dose escalation designed to investigate the safety, tolerability, and pharmacokinetic properties of Human CD19-CD22 Targeted T Cells Infusion. The primary objectives are to preliminarily assess the impact of Human CD19-CD22 Targeted T Cells Infusion in patients with relapsed/refractory B-cell acute lymphoblastic leukemia and to explore the appropriate dose and reinfusion schedule for phase II. Eligible participants, including those with Central Nervous System Lymphoma, B Cell Lymphoma (BCL), Acute Lymphocytic Leukemia (ALL), Acute Lymphoblastic Leukemia (ALL), B Acute Lymphoblastic Leukemia (B-ALL), Refractory Non-Hodgkin Lymphoma, Refractory Chronic Lymphocytic Leukemia (CLL), Refractory B Acute Lymphoblastic Leukemia (B-ALL), Diffuse Large B Cell Lymphoma, Lymphoid Leukemia, and MRD-positive cases, can participate. Eligibility will be determined through a comprehensive assessment, including disease evaluations, a physical examination, Electrocardiograph, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), and blood tests. Prior to the infusion of CD19-CD22 CAR+ T cells, participants will undergo chemotherapy. After the infusion, participants will be closely monitored for potential side effects and the effectiveness of CD19-CD22 CAR+ T cells. Certain study procedures may be conducted during hospitalization.
