Detailed Description:

This study was designed to explore a new dosing approach. Subjects began dosing at 10 mg bid and had the opportunity for dose increases based on assessments of efficacy and overall anemia status in a defined prior dosing interval. The dose could be increased up to a maximum dose of 20 mg bid. This approach assumes that beginning at a low dose for initial therapy may impact the rate of the initial hemoglobin decline and the nadir, by decreasing the level of JAK-mediated inhibition of hematopoiesis. Specific dose modifications were described to minimize excursions of hemoglobin levels into the Grade 3 or Grade 4 range.

Criteria

Inclusion Criteria:

  • Diagnosis of Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (PPV-MF), or Post-Essential Thrombocythemia Myelofibrosis (PET-MF) as confirmed by bone marrow biopsy.
  • Must score at least 2 points on the Dynamic International Prognostic Scoring System (DIPSS) scale for prognostic risk factors.
  • Peripheral blast count < 5% at both Screening and Baseline hematology assessments.
  • Must discontinue all drugs used to treat underlying myelofibrosis (MF) disease no later than Day -1 (the day prior to starting ruxolitinib).
  • Must have hemoglobin value ≥ 6.5 g/dL and be willing to receive blood transfusions.
  • Platelet count ≥ 100*10^9/L.
  • Must have a palpable spleen.

Exclusion Criteria:

  • Inadequate liver or bone marrow reserves, end stage renal disease on dialysis, clinically significant concurrent infections requiring therapy, or unstable cardiac function.
  • Invasive malignancies over the previous 5 years (except treated early stage carcinomas of the skin, completely resected intraepithelial carcinoma of the cervix, and completely resected papillary thyroid and follicular thyroid cancers).
  • Splenic irradiation within 6 months prior to receiving the first dose of study medication.
  • Life expectancy less than 6 months.
