Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Allogeneic γδT cell immunotherapy
Patients will receive 3 cycles of ex-vivo expanded allogeneic γδT cells treatments, at four-weeks' 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).
Ex-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.
