NCT ID NCT01174108

First seen Jun 25, 2026 · Last updated Jul 01, 2026 · Updated 3 times

Summary

This study tests a new way to do stem cell transplants for people with severe aplastic anemia or other bone marrow failure diseases. Doctors give a smaller number of donor white blood cells along with the stem cells to try to reduce serious side effects. Up to 120 patients aged 4 to 80 will take part, and they will be followed for up to 3 years.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Donor stem cells and white blood cells

What this could lead to

If successful, this approach could make stem cell transplants safer and more effective for people with severe blood diseases.

What could go wrong

This is an early Phase 2 trial with only 120 participants, so results may not apply to everyone. There are still risks of serious side effects like graft-versus-host disease or infection.
