Brief 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.

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.

Conditions

Non-Hodgkin's Lymphoma (NHL); Peripheral T Cell Lymphoma (PTCL)

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Allogeneic γδT cell immunotherapy

Patients will receive 2 cycles of ex-vivo expanded allogeneic γδT cells treatments, at 14 days' intervals, each cycle has 2 infusions. Ex-vivo expanded γδT cells are transfused to patients in a dosage escalated manner (Dose escalation, 1×107, 3×107, 9×107 per kg of body weight).

Group Type: EXPERIMENTAL

Ex-vivo expanded allogeneic γδT cells

Intervention Type: BIOLOGICAL

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.
