About this trial

This phase II trial studies how well ruxolitinib works in treating patients with hypereosinophilic syndrome or primary eosinophilic disorders.

Eligibility criteria

Qualifiers

Has as at least 2 readings with an absolute eosinophil count >= 1,500/mm^3 in the preceding 3 months prior to starting ruxolitinib (one reading must be during the screening period).

Dependent, intolerant or refractory to corticosteroids OR has relapsed/refractory disease to other therapy besides corticosteroids.

Symptomatic from his/her disease OR has one or more signs of organ damage (assessed by the investigator as possibly-related to eosinophilia or biopsy-proven). This can include skin, lung, cardiac, central nervous system, liver, or gastrointestinal (GI) involvement, or evidence of symptomatic hepatic or splenic enlargement.

Subject with lymphocyte-variant hypereosinophilia must meet the following

Disqualifiers

Active life-threatening complication(s) from underlying eosinophilic disease (i.e., leukostasis; acute thromboembolic disease including central nervous system (CNS) involvement; severe pulmonary or cardiac dysfunction). Stabilization of acute, life-threatening eosinophil-related co-morbidities will allow enrollment of the patient.

World Health Organization (WHO)-defined myeloid neoplasm associated with eosinophilia other than CEL NOS and JAK2 rearranged neoplasms (e.g., myelodysplastic syndrome (MDS); myeloproliferative neoplasms (MPN); MDS/MPN overlap disorders; and systemic mastocytosis (SM).

Reactive hypereosinophilia due to connective tissue disease, sarcoidosis or eosinophilic granulomatosis with polyangiitis.

Organ-restricted ?tissue? eosinophilia with the absence of peripheral eosinophilia in the blood.
