Personalized dosing of Immune-Suppressing drug may improve stem cell transplant outcomes
NCT ID NCT05166967
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial tested whether giving an individualized dose of antithymocyte globulin (ATG) based on a patient's own drug levels works better than a standard fixed dose. The goal was to reduce graft-versus-host disease (a serious immune reaction) and virus reactivation after a half-matched stem cell transplant. The study enrolled 204 patients and compared survival without these complications between the two dosing groups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- antithymocyte globulin (ATG)
- What this could lead to
- If successful, this could show that tailoring ATG doses reduces serious complications like graft-versus-host disease and viral infections after stem cell transplants.
- What could go wrong
- This is a completed phase 3 trial, but results are not yet published. The approach may not significantly improve outcomes over standard fixed dosing, and risks like infection or graft failure remain.
