• 1 other identifier: BHCT-RD13-02-11
• Study Type: interventional
• Target: 6
• Locations: 1 country

Brief Summary

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.

Conditions

Hematologic Malignancies

Outcome Measures

Primary Outcomes (3)

• Overall response rate, ORR

  The proportion of patients with CR (complete response) /CRi (complete response with incomplete blood cell recovery) and PR (partial response).

  Evaluate at 4 weeks after CAR-T infusion

• Overall response rate, ORR

  The proportion of patients with CR (complete response) /CRi (complete response with incomplete blood cell recovery) and PR (partial response).

  Evaluate at 8 weeks after CAR-T infusion

• Overall response rate, ORR

  The proportion of patients with CR (complete response) /CRi (complete response with incomplete blood cell recovery) and PR (partial response).

  Evaluate at 12 weeks after CAR-T infusion

Secondary Outcomes (5)

• Overall response rate with MRD-negative, MRD-ORR

  Up to 1 years after CAR-T infusion

• Duration of remission, DOR

  Up to 1 years after CAR-T infusion

• Event-free survival, EFS

  Up to 1 years after CAR-T infusion

• The proportion of patients who receive hematopoietic stem cell transplantation

  Up to 1 years after CAR-T infusion

• Overall survival, OS

  Up to 1 years after CAR-T infusion

• Diagnosis of r/r T-ALL/LBL.
• CD7 positive expression
• Bone marrow lymphoblasts ≥5% by morphologic evaluation at screening
• 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

• Subjects with some cardiac conditions will be excluded.
• With uncontrolled active central nervous system leukemia (CNSL), cerebrospinal fluid grade CNS3.
• 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.
