   description

   All participants received oral ruxolitinib. Patients began treatment with either 10 mg twice a day (bid), 15 mg bid, 25 mg bid, 50 mg bid, 25 mg once a day (qd), 50 mg qd, 100 mg qd, or 200 mg qd, depending on the time period when they entered the study. The doses were titrated based on efficacy and safety to a maximum of 25 mg bid for patients who entered the study after sufficient dosing information had been obtained to define the maximum dose for patients in the study. Patients could continue receiving treatment indefinitely if receiving benefit at a dose that continues to maintain benefit but does not exceed a maximum dose of 25 mg BID.

   Treatment-Emergent AEs are events occurring after first drug administration or worsened from baseline. Treatment-Related AEs are those with a definite, probable, possible or missing causality. A serious AE is a medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is a medical event requiring intervention to prevent 1 of the above. A severe or life-threatening AE is based on intensity, according to National Cancer Institute-Common Toxicity Criteria for Adverse Effects (NCI-CTCAE) v3.0.
