First seen Jan 06, 2026 · Last updated Apr 29, 2026 · Updated 22 times

Summary

This study tests the drug ruxolitinib in 10 people with hypereosinophilic syndrome or related disorders, where high levels of eosinophils (a type of white blood cell) cause organ damage. The goal is to see if ruxolitinib can lower eosinophil counts and improve symptoms. Participants must have tried other treatments without success or be unable to take them.
