Can lower drug doses make stem cell transplants safer for seniors?
NCT ID NCT05849207
First seen Jun 24, 2026 · Last updated Aug 06, 2026 · Updated 4 times
Summary
This study is for people aged 65 and older with blood cancers who are getting a stem cell transplant. Researchers want to see if giving a lower dose of the drug cyclophosphamide after the transplant can reduce serious side effects while still controlling the cancer. The trial will test four different dose levels in a small group of 26 participants to find the safest and most effective dose.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- cyclophosphamide
- What this could lead to
- If successful, this could help older patients receive stem cell transplants with fewer severe side effects, making the treatment safer and more tolerable.
- What could go wrong
- This is a very early phase 1 trial with only 26 participants, so results may not apply broadly. Lowering the dose might increase the risk of graft-versus-host disease or transplant failure.
