Could less chemo be better after stem cell transplants?

NCT ID NCT07193420

First seen Nov 01, 2025 · Last updated Jun 22, 2026 · Updated 45 times

Summary

This phase 3 trial tests whether a lower dose of the chemotherapy drug cyclophosphamide can reduce side effects after a half-matched stem cell transplant for blood cancers. The standard dose often causes complications, so researchers want to see if a lower dose works just as well. The study will follow 180 adults for two years to compare survival, relapse rates, and quality of life.

What this could mean

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

Active substance

Cyclophosphamide (a chemotherapy drug)

What this could lead to

If successful, a lower dose of cyclophosphamide could reduce side effects and improve survival without severe complications after stem cell transplants.

What could go wrong

This is an early-stage trial with only 180 participants, so results may not apply to everyone. Lowering the dose might also reduce its effectiveness in preventing graft-versus-host disease.

Conditions
