Masking no masking
Escalating doses of ruxolitinib from 5 mg BID to 15 mg BID in combination with panobinostat from 10 to 30 mg tiw QOW depending on determination of MTD of each drug
panobinostat LBH589
Given 3 times a week, every other week in 28-day cycles.
ruxolitinib INC424
Given twice daily in 28-day cycles.

Primary Outcomes

Rate of dose limiting toxicities at the different dose levels
time frame: Baseline, end of Cycle 1

Secondary Outcomes

Percentage of Responders achieving at least a 35% reduction in splenic volume (compared to baseline) at Week 12, or end of study, whichever comes first as determined by MRI/CT
time frame: Baseline, Week 12
Percentage of responders as measured by improvement in bone marrow fibrosis as graded according to the International Working Group consensus criteria for treatment response as compared to baseline
time frame: Baseline, Week 24 and 48
Percentage of Responders as measured by Summary statistics in absolute values at each visit and absolute and percentage change from baseline at each visit for change in JAK2V617F allele burden and cytokine measurement
time frame: Baseline, up to Week 48
Proportion of patients who are transfusion dependent, as well as, the proportion of patients whose transfusion status (dependent or independent) changed (from dependent to independent or vice versa) at each cycle as compared to baseline
time frame: Baseline, up to End of Treatment
Percentage of Responders as measured by a change in spleen length of at least 50% reduction as determined by manual palpation from Baseline to Week 12 and maintained until Week 24
time frame: Baseline, Week 12 and 24
Rate of adverse events, serious adverse events, notable laboratory, vital signs and ECG results by dose level
time frame: baseline, up to end of study
AUC and Cmax of ruxolitinib and panobinostat at various dose levels
time frame: Cycle 1 Day 1, up to Cycle 1 Day 6
