Granulocyte transfusions for children after umbilical cord blood transplant

The Use of Granulocyte Transfusions After Umbilical Cord Blood Transplant for Leukaemia: a Prospective, Non-randomised, Single-centre Study to Evaluate Safety and Immune Reconstitution

Not applicable Interventional University of Manchester · NCT05425043

This study tests whether giving white blood cells from donors to children after a cord blood transplant can help them recover better and lower the risk of complications.

What this trial studies

This study investigates the effects of granulocyte transfusions in children undergoing umbilical cord blood hematopoietic stem cell transplantation (HSCT) for high-risk acute leukemia. The approach aims to enhance the recovery of the donor immune system and reduce complications such as graft-versus-host disease (GVHD). By administering white blood cells from donors, the researchers hope to stimulate the expansion of the donor's immune cells, improving the chances of a successful transplant. The study focuses on children under 16 years old who meet specific eligibility criteria.

Who should consider this trial

Good fit: Ideal candidates for this study are children under 16 years old with high-risk acute leukemia who are undergoing their first allogeneic umbilical cord blood HSCT.

Not a fit: Patients who are not undergoing HSCT or those with contraindications to granulocyte transfusions will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve survival rates and reduce complications for children with refractory leukemia undergoing HSCT.

How similar studies have performed: While the use of granulocyte transfusions in HSCT is a promising approach, it remains relatively novel and has not been extensively tested in this specific context.
