New trial aims to make stem cell transplants safer for blood cancer patients

NCT ID NCT03970096

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase II trial is testing two different methods to reduce graft-versus-host disease (GVHD) in patients with acute leukemia or myelodysplastic syndrome (MDS) who are receiving a donor stem cell transplant. One method removes certain immune cells from the donor cells before transplant, and the other uses a drug after transplant. The goal is to see which approach leads to better survival without severe GVHD or relapse. The study plans to enroll 120 participants.

What this could mean

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

Active substance
Selective depletion of CD45RA+ naïve T cells or post-transplant cyclophosphamide
What this could lead to
If successful, this could lead to safer stem cell transplants with fewer severe side effects, improving survival and quality of life for leukemia and MDS patients.
What could go wrong
This is a mid-stage trial with only 120 participants, so results may not apply to everyone. Both strategies have risks, including infection or graft failure.
