CD5 CAR T-Cell Therapy for r/r T-cell Lymphomas

A Multicenter, Open-Label, Non-Randomized, Single-Arm Phase I/II Clinical Study of Autologous and New Donor CD7 CAR-T Cells for Relapsed or Refractory Mature T-Cell Lymphomas

Sponsor

Beijing GoBroad Hospital

Enrollment

36 participants

Start Date

Jun 1, 2025

Study Type

INTERVENTIONAL

Conditions

T-cell Non-Hodgkin Lymphoma T-cell Lymphoma (PTCL and CTCL)

Summary

This is a multi-center, open-label, non-randomized, single-arm clinical trial. Refractory/relapse T-NHL patients are treated with autologous and allogeneic CD5 CAR T-cell therapy. The primary objective is to prospectively evaluate the safety of CD5 CAR T cell bridging to HSCT in the treatment of r/r T-NHL. The primary endpoint is the type and incidence of dose limiting toxicity (DLT) within 21 days after CD5 CAR-T cell infusion. A total of 36 subjects is estimated to be enrolled.

Eligibility

Interventions

DRUGCD5 CAR-T cells infusion

Approximately 3-5 days prior to CD5 CAR-T cell infusion, subjects are treated with FC regimen (fludarabine and cyclophosphamide) for lymphodepletion. CAR-T cell infusion are performed 48 h after completion of chemotherapy.
