Overview

Brief Summary

This is a single-arm, open-label pilot study to evaluate the safety and efficacy of CD19-targeted allogenic CAR-T cells (19UCART) in patients with relapsed/refractory B-cell hematologic malignancies. 12 patients are planned to be enrolled in the dose-escalation trial. The primary objective of the study is to evaluation of the safety and feasibility of 19UCART for the treatment of relapsed/refractory B-cell hematologic malignancies. The secondary objective is to evaluate the efficacy of 19UCART for the treatment of relapsed/refractory B-cell hematologic malignancies. The exploratory objective is to evaluate expansion, persistence and ability of 19UCART to deplete CD19 positive cells in patients with relapsed/refractory B-cell hematologic malignancies.

Inclusion Criteria

  • Voluntary participation in this trial with signed informed consent.
  • Diagnosis of B-cell hematologic malignancy according to the 2017 WHO classification, including B-acute lymphoblastic leukemia (B-ALL) and mature B-cell lymphomas such as diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), marginal-zone lymphoma (MZL), small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL), mantle-cell lymphoma (MCL), etc.
  • Refractory or relapsed B-cell malignancy defined as failure to achieve complete remission after standard therapy, or relapse after achieving remission with first-line or salvage therapy.
  • Persistence of minimal residual disease (MRD) positivity despite hematologic remission in B-cell acute lymphoblastic leukemia (ALL).
  • At least one measurable lesion ≥1.5 cm in longest diameter by IWG revised criteria for relapsed/refractory lymphoma.
  • Age 18-70 years; both sexes eligible.
  • Expected survival ≥12 weeks.
  • Adequate organ function as follows (no blood products or growth factors within 14 days before first infusion):
  • . Hematology: A. White blood cell count (WBC) ≥3.0×10⁹/L B. Absolute neutrophil count (ANC) ≥1.5×10⁹/L C. Platelet count (PLT) ≥100×10⁹/L D. Hemoglobin (Hb) ≥90 g/L 2). Renal: A. Serum creatinine ≤1.5×ULN or calculated creatinine clearance ≥60 mL/min 3). Cardiac: A. Left ventricular ejection fraction (LVEF) ≥50 % B. QTc (Fridericia) ≤450 ms (men) or ≤470 ms (women) 4). Hepatic: A. Total bilirubin ≤1.5×ULN B. Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) ≤2.5×ULN (≤5×ULN if liver involvement) 5). Coagulation: A. International normalized ratio (INR) or Prothrombin time (PT) ≤1.5×ULN B. Activated partial thromboplastin time (APTT) ≤1.5×ULN 6). Pulmonary: Diffusing capacity of the lung (DLCO) ≥50 % of predicted (with or without correction for anemia/alveolar volume).
  • 9\. ECOG performance status 0-2 at screening.

Exclusion Criteria

  • Subjects with any of the following conditions are ineligible for this trial:
  • Known hypersensitivity, allergic reaction, intolerance, or contraindication to 19UCART or any study-drug component (including fludarabine, cyclophosphamide, or tocilizumab), or history of severe anaphylaxis.
  • Post-allo-HSCT relapse with active graft-versus-host disease requiring systemic corticosteroids or other immunosuppressants.
  • Uncontrolled active infection of any etiology.
  • Active hepatitis B, hepatitis C, or tuberculosis.
  • HIV or syphilis infection.
  • Active autoimmune disease or history of severe autoimmune disorder (as judged by the PI) requiring prolonged immunosuppressive therapy.
  • Congenital or acquired immunodeficiency syndromes.
  • New York Heart Association (NYHA) class III or IV heart failure, unstable angina, myocardial infarction within 6 months, or sustained (\>30 s) ventricular arrhythmia.
  • History of epilepsy or other significant central nervous system disorders.

Arms & Interventions

relapsed/refractory B-cell hematologic malignancies

Experimental

relapsed/refractory B-cell hematologic malignancies patients to be treated with 19UCART cells

Intervention: 19UCART injection (Biological)

Outcomes

Primary Outcomes

Toxicity and adverse-event grading after 19UCART treatment

Time Frame: up to 12 months after infusion

all toxicities and AEs will be assessed according to the National Cancer Institute CTCAE v5.0

CRS grading after 19UCART treatment

Time Frame: up to 12 months after infusion

CRS will be graded using the Lee DW et al. CRS grading scale

Secondary Outcomes

  • Overall response rate (ORR = CR + PR) of patients receive 19UCART treatment(1, 3, 6, and 12 months after infusion)
  • CAR copies and cell count of CAR-T in blood after 19UCART treatment(Day 0, 1, 3, 5, 7, 9, 11, 14, 21, 28, and month 2, 3, 6, 9, 12 after infusion)
  • Disease control rate (DCR = CR + PR + SD) of patients receive 19UCART treatment(1, 3, 6, and 12 months after infusion)
  • PET-CT Response Criteria according to Lugano metabolic response categories(1, 3, 6, and 12 months after infusion)
