Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the effect of re-treatment with ruxolitinib on reduction in spleen volume of at least 20% from baseline, by Week 24;Secondary Objective: 1. To evaluate the effect of re-treatment with ruxolitinib on reduction in spleen volume of at least 35% from baseline, by Week 24 2. To evaluate the effect of re-treatment with ruxolitinib on reduction in spleen length of at least 25% and 50% respectively, from baseline, by Week 24 3. To evaluate the effect of re-treatment with ruxolitinib on reduction in spleen volume and length over time 4. To evaluate the safety after re-treatment with ruxolitinib 5. To evaluate the effect of re-treatment with ruxolitinib on reduction in MPNSAF TSS of at least 25% and 50% respectively, from baseline, by Week 24 6. To evaluate the effect of re-treatment with ruxolitinib on reduction in MPNSAF TSS over time 7. To evaluate the effect of re-treatment with ruxolitinib on Patient Global Impression of Change (PGIC) 8. To evaluate the effect of re-treatment with ruxolitinib on EORTC QLQ-C30 and EQ-5D-5L;Primary end point(s): Proportion of patients achieving ?20% reduction from baseline in spleen volume by Week 24 after re-treatment with ruxolitinib;Timepoint(s) of evaluation of this end point: By week 24

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: 1. By Week 24 2. By Week 24 3. Each visit 4. Each visit 5. By Week 24 6. Each visit 7. Each visit measured 8. Each visit measured;Secondary end point(s): 1. Proportion of patients achieving greater than or equal to 35% reduction from baseline in spleen volume by Week 24 after re-treatment with ruxolitinib 2. Proportion of patients achieving greater than or equal to 25% and 50% reduction respectively, from baseline, in spleen length by Week 24 after re-treatment with ruxolitinib 3. Change in spleen length as well as in spleen volume from baseline to each visit where measured after re-treatment with ruxolitinib 4. Safety will be assessed by monitoring the frequency, duration and severity of Adverse Events, and evaluating changes in vital signs, electrocardiograms (ECGs), serum chemistry, hematology and urinalysis results 5. Proportion of patients achieving greater than or equal to 25% and 50% reduction respectively, from baseline in total symptom score (MPN-SAF TSS) by Week 24 after re-treatment with ruxolitinib 6. Change in MPN-SAF TSS from baseline to each visit where measured after re-treatment with ruxolitinib 7. PGIC at each visit where measured after retreatment with ruxolitinib 8. Change in EORTC QLQ-C30 and EQ-5D-5L scores from baseline to each visit where measured after re-treatment with ruxolitinib
