Summary

This trial looks at how well a drug called ruxolitinib works in treating patients with a condition called hypereosinophilic syndrome or another condition called primary eosinophilic disorders.

Who is the study for?
This trial is for patients with hypereosinophilic syndrome or primary eosinophilic disorders, including those newly-diagnosed, on corticosteroids, or with relapsed/refractory disease. Participants must have symptoms of organ damage or enlargement and an absolute eosinophil count >= 1,500/mm^3 (or >= 500/mm^3 in certain conditions). They should be able to consent and have a performance status <= 3. Exclusions include life-threatening complications from the disease, recent serious infections, low platelet counts, prior JAK inhibitor therapy like ruxolitinib.
What is being tested?
The trial is testing Ruxolitinib's effectiveness for treating hypereosinophilic syndrome or primary eosinophilic disorders. It's a phase II study which means they're looking at how well it works and its safety in people who fit the criteria.
What are the potential side effects?
Ruxolitinib may cause side effects such as infection risk due to immune system suppression; changes in blood counts leading to anemia; liver enzyme elevations suggesting potential liver injury; dizziness; headache; and possible weight gain.
