Ruxolitinib Phosphate and Danazol in Treating Anemia in Patients With Myelofibrosis
Trial status: Open for Enrollment
Why is this study being done?
I. To evaluate the efficacy (best overall response) of ruxolitinib (ruxolitinib phosphate) and danazol in patients with myelofibrosis suffering from anemia.
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.
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.
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 up to 6 courses in the absence of disease progression or unacceptable toxicity.

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