Sequential CAR-T Cells Therapy for CD5/CD7 Positive T-cell Acute Lymphoblastic Leukemia and Lymphoblastic Lymphoma Using CD5/CD7-Specific CAR-T Cells
Sponsor: Essen Biotech
Summary
Chimeric antigen receptor (CAR)-modified T cells targeted against CD19 have demonstrated unprecedented successes in treating patients with hematopoietic and lymphoid malignancies. Besides CD19, many other molecules such as CD22, CD30,BCMA,CD123, etc. may be the potential to develop the corresponding CAR-T cells to treat patients whose tumors express those markers. In this study, investigators will evaluate the safety and efficacy of Sequential CAR-T Cells Targeting CD5/CD7 in patients with patients with relapsed or refractory T-ALL/LBL/ETP-ALL. The primary goal is safety assessment including cytokine storm response and any other adverse effects. In addition, disease status after treatment will also be evaluated.
Official title: This is an Open, Single-arm, Clinical Study to Evaluate the Efficacy and Safety of Anti-CD7/CD5 CAR-T Cells in the Treatment of Relapsed or Refractory T-cell Acute Lymphoblastic Leukemia (T-ALL), ETP-ALL, and Lymphoblastic Lymphoma (TLBL).

CD5/CD7 CAR-T
The intervention in this clinical trial involves a novel approach using CD5/CD7 Chimeric Antigen Receptor T (CAR T) cells combined with chemotherapy. The goal is to assess safety and efficacy in patients with specific hematologic malignancies. Treatment Regimen: Patients in the trial will undergo the following regimen: Fludarabine Phosphate (Days -4 to -2): IV administration of fludarabine phosphate over 30 minutes on days -4 to -2. It's part of the preparatory regimen to enhance the body's response to CAR T-cell therapy. Cyclophosphamide (Day -2): IV cyclophosphamide over 60 minutes on day -2. CD5/CD7 Chimeric Antigen Receptor T Cells (Day 0): IV administration of investigational therapy, CD5/CD7 CAR T cells, over 10-20 minutes on day 0. Additional Doses: Eligible patients responding well to the initial CD5/CD7 CAR-T cell infusion without unacceptable side effects and sufficient CAR-T cell availability may receive 2 or 3 additional doses.
