Primary Outcome Measures :
  1. Part 1 : Treatment Emergent Adverse Events (TEAE'S) [ Time Frame: 24 Weeks ]
    Defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study treatment up to 30 days after last dose of study treatment.

  2. Part 2 : Spleen Volume Reduction by MRI/CT Scan [ Time Frame: 24 weeks ]
    Defined as the proportion of participants who have a reduction in spleen volume (by imaging) of at least 35 percent when compared with baseline.

  3. Part 2 : Spleen Volume Reduction [ Time Frame: 24 weeks ]
    Defined as the proportion of participants who have a reduction in spleen volume (by imaging) of at least 35% when compared with baseline.


Secondary Outcome Measures :
  1. Part 2 : Treatment Emergent Adverse Events (TEAE'S) [ Time Frame: 13 months ]
    Defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study treatment up to 30 days after last dose of study treatment.

  2. Part 2 : Improvement in Total Symptom Score (TSS) [ Time Frame: 24 Weeks ]
    Defined as the proportion of participants who achieve at least 50% reduction in TSS over the 28 days immediately before the end of Week 24 compared with the 7 days immediately before the initiation of itacitinib IR (baseline).

  3. Part 2 : Improvement in quality of life. [ Time Frame: 24 weeks ]
    Defined as the mean change in the 5 multi-item functional scale scores and the multi-item global health status scale score (EORTC QLQ-C30).

  4. Part 2 : Improvement in Patient Global Impression of Change (PGIC) [ Time Frame: 24 Weeks ]
    Defined as percentage of participants who are categorized as improved
