Male or female, at least 2 years of age for imatinib therapy and 18 years of age or older for ruxolitinib therapy
Must not have
HIV positivity or other known immunodeficiency
D816V KIT-positive systemic mastocytosis

Follow Up 1, 3, 6, 9, and 12 months
Awards & highlights
No Placebo-Only Group

Summary

This trial is for patients with a rare blood disorder called hypereosinophilic syndrome, who have not responded to standard treatment. The study will test whether the drug imatinib mesylate (Gleevec) is safe and effective in reducing blood eosinophils in these patients.

Who is the study for?
This trial is for individuals with myeloid hypereosinophilic syndrome, characterized by high eosinophil counts and organ damage. Participants must be at least 2 years old for imatinib or 18+ for ruxolitinib therapy, agree to use effective contraception, and have no secondary causes of their condition. Those already on imatinib may join the dose reduction part of the study.
What is being tested?
The trial tests tyrosine kinase inhibitors: imatinib mesylate (Gleevec) starting at 400 mg daily, potentially reduced to 100 mg; and ruxolitinib in eligible patients. It aims to reduce blood eosinophilia in myeloid HES patients, assessing safety and efficacy through regular clinical evaluations.
What are the potential side effects?
Possible side effects include bone marrow suppression leading to low blood cell counts, liver enzyme elevation indicating potential liver damage, digestive issues from medication interactions like fluconazole overuse, and risks associated with tuberculosis reactivation during treatment.
