Could tailoring chemo by age make stem cell transplants safer for MDS patients?
NCT ID NCT07677306
First seen Jun 30, 2026 · Last updated Sep 17, 2026 · Updated 3 times
Summary
This study looks at two different chemotherapy combinations given before a half-matched stem cell transplant in adults with myelodysplastic syndrome (MDS). One regimen is designed for people aged 55 and older to reduce side effects, while the other is a standard stronger regimen for younger patients. The goal is to see which approach leads to fewer deaths related to the transplant itself within the first year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- busulfan, cytarabine, cyclophosphamide, fludarabine, semustine, antithymocyte globulin
- What this could lead to
- If successful, this could help tailor chemotherapy doses before transplant to lower the risk of death from the procedure for people with myelodysplastic syndrome.
- What could go wrong
- This is a mid-stage study with 120 participants, so results may not apply to all patients. Chemotherapy before transplant can cause serious side effects like organ damage and infection.
