Can a cancer drug make stem cell transplants safer for myelofibrosis patients?

NCT ID NCT04384692

First seen Oct 31, 2025 · Last updated Jun 23, 2026 · Updated 34 times

Summary

This study tests whether giving the drug ruxolitinib before, during, and after a donor stem cell transplant can prevent graft-versus-host disease (GVHD) in people with myelofibrosis. GVHD is a serious complication where donor cells attack the patient's body. The trial involves 53 adults with intermediate- or high-risk myelofibrosis. Ruxolitinib is already used to reduce symptoms like an enlarged spleen and night sweats, and researchers hope it will also lower GVHD risk and improve survival.

What this could mean

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

Active substance

ruxolitinib

What this could lead to

If successful, this approach could reduce severe graft-versus-host disease and improve survival and quality of life for myelofibrosis patients undergoing stem cell transplant.

What could go wrong

This is a small Phase 2 trial with only 53 participants, so results may not apply to all patients. Ruxolitinib can cause side effects like infections and low blood counts.
