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.

Condition or disease Intervention/treatment Phase
Anemia Primary Myelofibrosis Secondary Myelofibrosis Drug: ruxolitinib phosphate Drug: danazol Other: quality-of-life assessment Other: questionnaire administration Phase 2

Detailed Description:


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 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.

Primary Outcome Measures :
  1. Best Overall Response Rate as Determined by International Working Group Criteria [ Time Frame: Up to 2 years ]
    Best overall response rate as determined by International Working Group criteria: An evaluable patient will be classified as a responder for the primary endpoint if the patient's best overall response is CR, PR or CI (Clinical Improvement) as determined by International Working Group Criteria over all cycles of study treatment. The percentage of successes will be estimated by the number of successes (defined as complete response, partial response, or clinical improvement) divided by the total number of evaluable patients times 100. Confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.

Secondary Outcome Measures :
  1. Survival Time [ Time Frame: From registration to death due to any cause, assessed up to 2 years ]
    Survival time is defined as the time from registration to death due to any cause. The distribution of survival time will be estimated using the method of Kaplan-Meier. The median and 95% confidence interval are reported below.

  2. Toxicity, Assessed Using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0 (v4) [ Time Frame: Up to 2 years ]
    The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns within patient groups. In addition, we will review all adverse event data that is graded as 3, 4, or 5 and classified as either "unrelated" or "unlikely to be related" to study treatment in the event of an actual relationship developing. The overall toxicity rates (percentages) for grade 3 or higher adverse events considered at least possibly related to treatment are reported below.

Other Outcome Measures:
  1. Patient-reported Symptoms Assessed Using the MPN-SAF, as Measured by the Percentage of Patients With a Decrease in MPN-SAF TSS Greater Than 50% From Baseline [ Time Frame: Baseline to up to 2 years ]
    Patient-reported symptoms will be described at each time point using the mean, confidence interval, median, and range. The Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) will be analyzed using published scoring algorithms. MPN-SAF includes 27 items scored on a scale of 0 to 10. The MPN-SAF Total Symptom Score (TSS) (range 0-100) was computed according to the published scoring algorithm. Higher scores represent worse symptom burden. The percentage of patients with a decrease in MPN-SAF TSS greater than 50% from baseline and 95% confidence interval are reported below.
