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.
