Brief Summary

Evaluation of Sup19 CAR-T cells in cases where previous CD19-targeted therapy has failed or where CD19 Evaluation of Safety and Efficacy in the Treatment of Low-Grade Hematological Malignancies: A Prospective, Single-Arm Clinical Study Research

Conditions

B-Acute Lymphoblastic Leukemia; B Acute Lymphoblastic Leukemia/Lymphoma

Outcome Measures

Primary Outcomes (1)

• Safety evaluation of Sup19 CAR-T cell therapy in patients with hematologic malignancies who have failed prior CD19-targeted therapy or exhibit weak CD19 expression: dose-limiting toxicity (DLT) adverse events (with particular focus on CRS and ICANS)

  up to 28 after CAR-T cell infusion

Secondary Outcomes (7)

• The best response rate of Sup19 CAR-T cell therapy within 3 months(The proportion of patients achieving CR/CRi)

  Sup19 CAR-T cell therapy within 3 months

• Duration of response (DOR)

  After the Sup19 CAR-T infusion, the time from the first achievement of CR/CRi + PR to disease recurrence or death due to leukemia (follow-up monitoring until 3 years after infusion).

• Event-free Survival, (EFS）

  The time from the administration of Sup19 CAR-T to the earliest occurrence of the event (follow-up monitoring until 3 years after infusion)

• Leukemia-free Survival, (LFS）

  The time from the first occurrence of CR/CRi (ALL/LBL) to recurrence or death. (follow-up monitoring until 3 years after infusion)

• The proportion of patients who received hematopoietic stem cell transplantation under the alleviated condition

  The proportion of subjects who achieved remission after infusion and who received HSCT. (Follow-up monitoring was conducted until 3 years after the infusion)

Study Arms (1)

3 dose groups

EXPERIMENTAL

Using a dose escalation and rapid titration design, the CAR-T dose groups were (1) 0.5×10\^6 CAR-T cells/kg; (2) 1×10\^6 CAR-T cells/kg; (3) 3×10\^6 CAR-T cells/kg.

Biological: Sup19 CAR-T

Interventions

Sup19 CAR-T BIOLOGICAL

The use of Sup19 CAR-T cells to treat hematologic malignancies with prior CD19-targeted therapy failure or CD19 weak expression aims to improve the relapse-free survival rate in patients with hematologic malignancies, providing a novel curative strategy for these patients.
