The objectives of the study are:

  1. Evaluation of the safety profile of imatinib mesylate in patients with idiopathic hypereosinophilic syndrome resistant or refractory to, or intolerant of, prednisone, hydroxyurea or interferon-alpha, or untreated patients carrying the Fip1L1-PDGFRA fusion protein.
  2. Evaluation of the efficacy of imatinib mesylate in patients with idiopathic hypereosinophilic syndrome
  3. Analysis of patient's blood samples for the detection of activated kinases.
