Measure:Change in spleen length from baseline
Time Frame:Baseline to day 1 and day 15 of Cycle 1, 2 and 3 (each cycle is 28 days), day 1 of all subsequent cycles, and the end of treatment (approx 12 cycles = 48 weeks)
Safety Issue:
Description:Change in spleen length measured in centimeters by manual palpation summarized at each time point using descriptive statistics in Part 2 and Part 3 of the study
Measure:Change in spleen volume from baseline
Time Frame:Baseline to the end of Cycle 6 (24 weeks), the end of Cycle 12 (48 weeks) and at the end of treatment if not performed in the past 12 weeks (up to 48 weeks)
Safety Issue:
Description:Change in spleen volume measured by magnetic resonance imaging (MRI) or computed tomography (CT) summarized at each time point using descriptive statistics, in Part 2 and Part 3 of the study
Measure:Change in symptoms of MFSAF v4.0 from baseline
Time Frame:Baseline to day 1 of Cycle 1, day 1 of all subsequent cycles of treatment (each cycle is 28 days), as well as the end of treatment visit (approximately 52 weeks)
Safety Issue:
Description:Change in total symptom scores (TSS) assessed by the Myelofibrosis (MF Symptom Assessment Form version 4.0 (MFSAF v4.0) at each time point in Part 2 and Part 3 of the study. The MFSAF v4.0 questionnaire focuses on the 7 core symptoms of MF: fatigue, night sweats, pruritus, abdominal discomfort, pain under the ribs on the left side, early satiety and bone pain. Subjects record symptom severity at it worst for each of the 7 symptoms on an 11-point numeric rating scale, from 0 (absent) to 10 (worst imaginable). The Total Symptom Score (TSS) is the sum of all the scores for all 7 symptoms.
Measure:Change in symptoms of EORTC QLQ-C30 from baseline
Time Frame:Baseline to day 1 of Cycle 1, day 1 of all subsequent cycles of treatment (each cycle is 28 days), as well as the end of treatment visit (approximately 52 weeks)
Safety Issue:

The EORTC QLQ-C30 includes 5 functional scales (physical, emotional, social, role, cognitive), eight symptom scales (fatigue, pain, nausea/vomiting, constipation, diarrhea, insomnia, dyspnea, and appetite loss), as well as global health/quality-of-life and financial impact. Subjects respond according to the past week recall period, with the exception of the first 5 questions that represent physical functioning and capture the subject's current status. Raw scores are linearly converted to a 0-100 scale. For functional and global health status/QoL higher scores indicate better QoL and level of functioning; for symptom scales, higher scores indicate greater level of symptoms or difficulties.
