Summary

A single centre randomised, controlled phase I cross-over trial in healthy volunteers to assess the recovery and survival of a mini-dose of red blood cells derived from CD34+cells isolated from adult blood vs standard donated red blood cells.

There are a small number of patients with rare blood group types for whom NHS Blood and Transplant cannot meet the transfusion requirements. New red blood cells can be grown from human blood stem cells in the laboratory. We hope that this will provide us with a novel transfusion product for these patients in the future, some of whom require regular transfusions throughout life (e.g. for thalassemia or sickle cell disease).

Study hypothesis

It is hypothesised that the manufactured RBCs will have a longer survival in the circulation of the volunteers than the standard donated RBCs.

Study design

Randomised, single blind, cross-over design to compare the recovery and survival of red blood cells manufactured from CD34+ cells isolated from adult blood compared with standard donated red blood cells. The order in which each recipient receives the standard or manufactured red blood cells is randomised and recipients will be blinded to that order.
