Summary

The purpose of this study was to evaluate the effect of an alternative dosing strategy of ruxolitinib in subjects with primary myelofibrosis (PMF), post-polycythemia vera-myelofibrosis (PPV-MF) and post essential thrombocythemia-myelofibrosis (PET-MF) in order to minimize the development of anemia and thrombocytopenia.

Conditions

  • Primary Myelofibrosis
  • Post-Polycythemia Vera Myelofibrosis
  • Post-Essential Thrombocythemia Myelofibrosis

Interventions

DRUG

Ruxolitinib

Ruxolitinib was provided as 5 mg tablets. Dose increases were only permitted at wks 12 \& 18 for lack of efficacy. Increases were restricted to patients who didn't meet criteria for a dose hold over the prior 6 wks, had a platelet count ≥ 100 x 10\^9/L at wk 12 or ≥ 150 x 10\^9/L at wk 18, and had a self-reported PGIC score of 3 (minimally improved) to 7 (very much worse) OR the subject's palpable spleen length below the costal margin was reduced by less than 40% relative to Baseline. Dose increases were elective and not required. Subjects were permitted a dose increase of 5 mg BID to 15 mg BID at wk 12 and to a maximum of 20 mg BID at wk 18. The protocol required dose decreases for thrombocytopenia (platelets \<100 x 10\^9/L) or protocol-defined anemia (decline in hemoglobin of at least 2 g/dL to a level \< 8 g/dL, development of transfusion dependence, or a 50% increase in transfusion requirements for transfusion dependent subjects).
