Conditions
Keywords
CD4-specific CAR T, T cell leukemia, T cell lymphoma, CD4CAR
Brief summary
This is a phase I, interventional, single arm, open label, treatment study to evaluate the safety and tolerability of CD4 CAR T cells in patients with relapsed and/or refractory T cell lymphoma.
Detailed description
CD4-specific CAR is a chimeric antigen receptor immunotherapy treatment designed to treat lymphoma/leukemia expressing CD4 antigen. CD4+ T cell lymphomas are a subset of leukemias and lymphomas that are positive for the surface protein CD4. The purpose of this study is to evaluate the efficacy and safety of CD4 CAR T cells.
Interventions
CD4 CAR T cells administered to patients, will be either fresh or thawed CAR T cells by IV injection after receiving lymphodepleting chemotherapy.

Intervention model description
Dose escalation phase: CD4 CAR T cells transduced with a lentiviral vector to express CD4 chimeric receptor domain on T cells with an escalation approach, 2e6 to 5e6 CAR-T cells/kg
