Details and patient eligibility

About

This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 CAR-T therapy for patients with CD7-positive relapsed or refractory T-ALL/LBL, and to evaluate the pharmacokinetics of CD7 CAR-T in patients.

Enrollment: 20 patients

Sex: All

Ages: 3 to 70 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Age 3-70
2. Diagnosis of r/r T-ALL/LBL.
3. CD7 positive expression
4. Bone marrow lymphoblasts ≥5% by morphologic evaluation at screening
5. Creatinine clearance (as estimated by Cockcroft Gault) ≥ 60 mL/min, Serum alanine aminotransferase(ALT)/aspartate aminotransferase(AST) < 3×upper limit of normal, Total bilirubin < 1.5×upper limit of normal or ≤1.5mg/dl
6. Left ventricular ejection fraction ≥ 50% .
7. Baseline oxygen saturation ≥ 92% on room air.
8. ECOG performance status of 0 to 2.
9. The estimated survival time is more than 3 months.
10. Subjects or their legal guardians volunteer to participate in the study and sign the informed consent.

Exclusion criteria

1. Sujects with concomitant genetic syndromes associated with bone marrow failure states.
2. Sujects with some cardiac conditions will be excluded.
3. 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.
4. History of malignancy other than non-melanoma skin cancer or carcinoma.
5. Primary immune deficiency.
6. Presence of uncontrolled infections.
7. Sujects with some anticancer therapy before CAR-T infusion will be excluded.
8. Active uncontrolled acute infections.
9. Known history of infection with human immunodeficiency virus (HIV); active or latent hepatitis B, hepatitis C and syphilis.
10. Subjects who are receiving systemic steroid therapy prior to screening.
11. Subjects with acute graft-versus-host disease (GvHD)
12. Having received live/attenuated vaccine within 4 weeks prior to screening.
13. History of allergy to any component of the cell therapy product.
14. Pregnant or breastfeeding women
15. Any other issue which, in the opinion of the investigator, would make the sujects ineligible for the study.
