Study Arms (1)
Fludarabine + Cyclophosphamide + anti-CD7 CAR-T Cells
EXPERIMENTALPatients 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.
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.

- Severe mental disorders;
- Have received organ transplantation (excluding bone marrow transplantation);
- 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.
