NCT04823091

Brief Summary

This is a single-center, open-label, single-arm study to evaluate the primary safety and efficacy of anti-CD7 chimeric antigen receptor(CAR)-modified T cells(CAR7-Ts) in patients with relapsed or refractory T lymphoid malignancies.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Treatment-related Adverse Events

    Therapy-related adverse events will be recorded and assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0).

    within 2 years after infusion

Secondary Outcomes (5)

  • Overall response rate(ORR) of administering CAR7-T cells in Relapsed/Refractory CD7+ T-cell hematological malignancies.

    within 2 years after infusion

  • Complete response rate(CRR) of administering CAR7-T cells in Relapsed/Refractory CD7+ T-cell hematological malignancies.

    within 2 years after infusion

  • Progress-free survival(PFS) of administering CAR7-T cells in Relapsed/Refractory CD7+ T-cell hematological malignancies.

    within 2 years after infusion

  • Duration of Response(DOR) of administering CAR7-T cells in Relapsed/Refractory CD7+ T-cell hematological malignancies.

    within 2 years after infusion

  • Overall survival(OS) of administering CAR7-T cells in Relapsed/Refractory CD7+ T-cell hematological malignancies.

    within 2 years after infusion

Other Outcomes (1)

  • In vivo expansion and survival of CAR7-T cells

    within 2 years after infusion

Study Arms (1)

Fludarabine + Cyclophosphamide + anti-CD7 CAR-T Cells

EXPERIMENTAL

Patients will received lymphodepletion with fludarabine (30 mg/kg) and cyclophosphamide (250 mg/kg) on day -5, -4, and -3, followed by the infusion of CAR7-T cells with the dose of 1×10\^6/kg and 2×10\^6/kg (with an allowance of ±20%). If no dose-limited toxicity (DLT) emerges in the group, then the subsequent higher dose will be used in the next group. If DLT emerges in a single subject in any dose level, 3 more subjects will be enrolled to the same dose level. The maximum dose could be extended.

Drug: Fludarabine + Cyclophosphamide + CAR7-T Cells

Interventions

fludarabine 30 mg/kg on day -5, -4, and -3; cyclophosphamide 250 mg/kg on day -5, -4, and -3; CAR7-T Cells on day 0.

Fludarabine + Cyclophosphamide + anti-CD7 CAR-T Cells

  • Female patients (fertile patients) had positive blood HCG test;
  • Hepatitis (including hepatitis B and C), AIDS and syphilis were screened positive;
  • Patients with graft-versus-host disease (GVHD) or who require immunosuppressant treatment;
  • The absolute value of lymphocytes was too low to manufacture CART cells;
  • Other conditions considered inappropriate by the researcher.
