Brief Summary

This phase II pilot trial studies how well ruxolitinib phosphate and danazol work in treating anemia in patients with myelofibrosis. Ruxolitinib phosphate and danazol may cause the body to make more red blood cells. They are used to treat anemia in patients with myelofibrosis.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the efficacy (best overall response) of ruxolitinib (ruxolitinib phosphate) and danazol in patients with myelofibrosis suffering from anemia.

SECONDARY OBJECTIVES:

I. To evaluate the overall survival of patients with myelofibrosis suffering from anemia initiating ruxolitinib and danazol.

II. To evaluate the adverse event profile of ruxolitinib and danazol in patients with myelofibrosis suffering from anemia.

TERTIARY OBJECTIVES:

I. To evaluate quality of life (QOL) and patient-reported symptoms using the Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) and European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) with ruxolitinib and danazol for patients with myelofibrosis suffering from anemia.

OUTLINE:

Patients receive ruxolitinib phosphate orally (PO) twice daily (BID) and danazol PO thrice daily (TID) on days 1-56. Treatment repeats every 56 days for 6 courses in the absence of disease progression or unacceptable toxicity. At the treating physician's discretion, patients may continue treatment past 6 courses if they are without disease progression.

After completion of study treatment, patients are followed up every 6 months for 2 years.

Eligibility

Criteria:

Inclusion Criteria:

- Histological confirmation of primary myelofibrosis (MF), post polycythemia vera (PV) or post essential thrombocythemia (ET) myelofibrosis (intermediate 1, intermediate II or high risk) requiring medical therapy

- Anemia is required for trial entry (defined as hemoglobin < 10g/dL or transfusion dependent [having needed a transfusion anytime in the past 6 months])

- Major surgery =< 28 days or radiation =< 6 months prior to registration
