简要总结
This study aims to evaluate the safety and tolerance of modified CD19 CAR T cells in treating refractory/relapsed B-cell malignancies. CAR-T cells will be investigated as a single agent both in relapsed/refractory B-cell acute lymphoblastic leukaemia (B-ALL) and up to 60% of patients with B-cell non-Hodgkin's lymphoma (NHL).

入选标准
- •Male or female aged 18-70 years;
- •Estimated survival time ≥ 12 weeks;
- •Histologically confirmed diagnosis of CD19+ B-ALL or CD19+ B-NHL(meeting one of the following conditions):
- •Ineffectively or relapses after 2 or more remedial treatments
- •Relapse after auto-HSCT or unsuitable for auto-HSCT;
- •At least one assessable tumor lesion;
- •ECOG performance status 0 to 2;
- •Creatinine clearance rate≥ 60 ml/min, ALT and AST ≤ 2.5 times of upper limit of normal, total bilirubin ≤ 1.5 times of upper limit of normal;
- •Male and female of reproductive potential must agree to use birth control during the study and for at least 30 days post study;
- •Patients or their legal guardians volunteer to participate in the study and sign the informed consent.
排除标准
- •Patients with other uncontrolled malignancies;
- •Previously treated with any CAR-T cell product or other genetically-modified T cell therapy;
- •Patients with HIV infection, hepatitis B (HBsAg positive) or hepatitis C(anti-HCV positive);
- •Patients with central nervous system involvement by lymphoma ,malignant cells in cerebrospinal fluid or history of brain metastasis;
- •Patients with atrial or ventricular involvement by B-cell malignancies;
- •Patients with tumor mass require urgent treatment, such as ileus or vascular compression;
- •Patients with severe disease or other uncontrolled diseases that were not suitable for this trial, such as coronary heart disease, angina pectoris, myocardial infarction, arrhythmia, cerebral thrombosis, cerebral hemorrhage, grade 2-3 hypertension;
- •Unstable pulmonary embolism, deep venous embolism, or other major arterial/venous thromboembolism events occurred within 30 days prior to randomization. If patients receive anticoagulant therapy, the treatment dose must be stable prior to randomization;
