Could a JAK inhibitor improve stem cell transplant success in myelofibrosis?

NCT ID NCT03427866

First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time

Summary

This phase 2 trial tests whether giving ruxolitinib (Jakafi) before, during, and after a stem cell transplant can improve outcomes for people with myelofibrosis. The study includes patients with intermediate-2 or high-risk disease, or intermediate-1 with additional risk factors. The main goal is to see if this approach increases the number of patients who survive one year without graft-versus-host disease or relapse.

What this could mean

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

Active substance
Ruxolitinib (Jakafi)
What this could lead to
If successful, this approach could reduce the risk of graft-versus-host disease and relapse after stem cell transplant for myelofibrosis.
What could go wrong
This is a phase 2 trial with a small number of participants, so results may not apply broadly. Ruxolitinib can cause side effects like low blood counts and infections.
