New stem cell combo aims to tame blood cancer with fewer side effects
NCT ID NCT07493538
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests a stem cell transplant using a milder chemo and radiation regimen for people with blood cancers like AML and MDS. The goal is to see if this approach improves survival at 100 days after transplant. Participants receive donor stem cells along with drugs to prevent graft-versus-host disease. The study is currently recruiting 132 patients aged 2 to 75.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Treosulfan, Fludarabine, total body irradiation, tacrolimus, and cyclophosphamide
- What this could lead to
- If successful, this could offer a safer stem cell transplant option for people with blood cancers, reducing side effects and improving survival.
- What could go wrong
- This is a mid-stage trial with only 132 participants, so results may not apply to everyone. There are risks of infection, graft-versus-host disease, and organ damage.
