Clinical Trial Summary

This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 Chimeric Antigen Receptor-T(CAR-T) therapy for patients with CD7-positive relapsed or refractory T-Acute Lymphoblastic Leukemia(ALL)/Lymphoblastic Lymphoma(LBL)/Acute Myelogenous Leukemia(AML), and to evaluate the pharmacokinetics of CD7 CAR-T in patients。

Exclusion Criteria:

1. Subjects with concomitant genetic syndromes associated with bone marrow failure states.

2. Isolated extramedullary lesions

3. Subjects with some cardiac conditions will be excluded.

4. With uncontrolled active central nervous system leukemia (CNSL), cerebrospinal fluid grade Central Nervous System3(CNS3).

5. History of traumatic brain injury, consciousness disturbance, epilepsy, cerebrovascular ischemia, and cerebrovascular hemorrhagic disease, which might compromise the ability of the subject to compliance with the obligations under the protocol.

6. History of malignancy other than non-melanoma skin cancer or carcinoma.

7. Primary immune deficiency.

8. Presence of uncontrolled infections.

9. Subjects with some anticancer therapy before CAR-T infusion will be excluded.
