Study summary

This study aims to evaluate the safety, tolerability and efficacy of ex-vivo expanded allogeneic γδT cells obtained from a blood-related donor of patients with relapsed or refractory B cell non-Hodgkin's lymphoma (B-NHL) or peripheral T cell lymphoma (PTCL) expect for γδT lymphoma.

Read the detailed description

This study is a single-center, non-randomized, open label, no control, prospective clinical trial to evaluate the safety, tolerability and efficacy of ex-vivo expanded allogeneic γδT cells from a blood-related donor of NHL or PTCL patients(except for γδT lymphoma). This study will include the following sequential phases: sign informed consent, γδT cell pre-culture, screening and registration to the trial, apheresis, γδT cell preparation, pre-treatment for lymphodepleting chemotherapy (selectable plan), treatments and follow-ups. The study will evaluate the safety and efficacy of the ex-vivo expanded allogeneic γδT cells in patients with relapsed or refractory non-Hodgkin's lymphoma (NHL) or peripheral T cell lymphoma (PTCL) expect for γδT lymphoma.

Study arms

  • Experimental
    Allogeneic γδT cell immunotherapy

    Biological: Ex-vivo expanded allogeneic γδT cells

Interventions

  • BiologicalEx-vivo expanded allogeneic γδT cells

    Cells will be extracted from a healthy donor by apheresis, followed by ex-vivo expansion and activation. The ex-vivo expanded γδT cells from donors will be adoptively transfused.

    PFS is defined as the time from the γδT cells infusion date to the date of disease progression or death from any cause.
