Brief Summary

This is a single-center, open-label, single-arm study to evaluate the primary safety and efficacy of universal chimeric antigen receptor-modified AT19 cells in patients with relapsed or refractory hem...

Detailed Description

* Adoptive transfer of autologous anti-CD19 CAR-T cells can induce durable remissions in patients with relapsed/refractory hematologic malignancies, including CD19+ B-cell acute lymphoblastic leukemia...

Eligibility Criteria

Inclusion

  • Aged 14-78 years old (including 14 and 78 years old).
  • Clinical diagnosis of CD19+ B-cell hematological malignancies, including acute lymphoblastic leukemia, chronic lymphocytic leukemia and lymphoma.
  • Refractory/Relapsed B-cell malignancies:
  • A. Refractory/relapsed B-cell lymphoblastic leukemia, meeting one of the following criteria:
  • i. Recurrence within 6 months after first remission. ii. Primary refractory disease which cannot achieve complete remission (CR) after 2 cycles of standardized chemotherapy regimen.
  • iii. Failure to achieve CR or relapse after one line or multiple lines of salvage chemotherapy.
  • iv. Not suitable for hematopoietic stem cell transplantation (HSCT), or abandon HSCT due to various restrictions, or relapse after HSCT.
  • B. Refractory/relapsed B-cell lymphoma, meeting 1 of the first 4 items plus item 5: i. Tumor shrinkage less than 50% or disease progression after 4 cycles of standard chemotherapy.
  • ii. Achieved CR after standard chemotherapy, but relapsed within 6 months. iii. 2 or more relapses after CR. iv. Not suitable for HSCT, or abandon HSCT due to various restrictions, or relapse after HSCT.
  • v. Subjects must have received adequate treatment in the past, including anti-CD20 monoclonal antibody and combination chemotherapy with anthracyclines.
  • Having a measurable or evaluable lesion:
  • A. Patients with lymphoma require a single lesion≥15mm or 2 or more lesions≥10mm.
  • B. Patients with leukemia require persistent positive or positive relapse of bone marrow MRD.
  • The toxicity related to previous treatments had returned to \< 1 level at enrollment (except for low grade toxicity such as alopecia).
  • Patients have good main organs functions:
  • A. Liver function: ALT/AST \< 2.5 times the upper limit of normal (ULN) and total bilirubin≤ 1.5 times ULN; B. Renal function: Creatinine clearance rate ≥ 60ml/min. C. Pulmonary function: Indoor oxygen saturation ≥ 95%. D. Cardiac Function: Left ventricular ejection fraction (LVEF) ≥50%, no clinically-significant ECG findings.
  • Estimated survival time≥3 months.
  • Patient or his or her legal guardian voluntarily participates in and signs an informed consent form.

Exclusion

  • Central nervous system is involved in leukemia and lymphoma.
  • Known HIV positive patients.
  • CNS diseases, such as epilepsy, cerebral ischemia / hemorrhage, dementia, cerebellar diseases or any CNS related autoimmune diseases.
  • NYHA class III or higher cardiac failure, or with malignant arrhythmia.
  • Myocardial infarction, angioplasty or stent placement, unstable angina or other clinically significant heart history within 12 months before enrollment.
  • Patients who need immediate treatment to control tumor progression or relieve tumor burden.
  • Active autoimmune diseases requiring systemic immunosuppressive therapy.
  • History of symptomatic deep vein thrombosis or pulmonary embolism within 6 months before enrollment.
  • Severe immediate hypersensitivity to any drug to be used in this study.
  • Women who are pregnant or breastfeeding.
  • Other unsuitable conditions in the researchers' opinion.
