Brief Summary:
Patients with severe thalassemia (thalassemia major) present with severe anemia that required life-long transfusion therapy, spleen enlargement that led to increased transfusion requirement, and other serious complications as early death, growth retardation, bone deformations and iron overload due to blood transfusions. Splenectomy can significantly reduce transfusion requirement in thalassemia patients, but it is associated with an increased risk of serious complications such as sepsis and thrombosis. Preliminary preclinical and clinical data suggested that JAK2 inhibition, by reducing spleen size, could improve hemoglobin levels, thereby eliminating the need for splenectomy and reducing transfusion requirement and related iron overload.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 30 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Single Arm, Multicenter, Phase IIa Study to Explore the Efficacy and Safety of Ruxolitinib (INC424) in Regularly Transfused Patients With Thalassemia
Actual Study Start Date : May 28, 2014
Actual Primary Completion Date : April 12, 2016
Actual Study Completion Date : April 12, 2016

Arm Intervention/treatment
Experimental: INC424 (ruxolitinib) - Study Treatment
Regularly transfused adult patients with thalassemia and spleen enlargement.
Drug: ruxolitinib
Ruxolitinib was taken at a starting dose of 10 mg twice daily with dose adjustments within the range of 5 to 25 mg twice daily.
Other Name: INC424

Primary Outcome Measures :
  1. Change of Hematocrit Adjusted Volume of Red Blood Cells (RBC) [ Time Frame: week 6 to week 30 interval ]
    Change of RBC transfusion requirement measured as percent change of the hematocrit-adjusted volume of transfused RBC and observed during within on-treatment interval (any time-points of RBC transfusion between week 6 and week 30 driven by the individual patient's need) compared to baseline (defined by pre-treatment interval between Week - 24 to start of treatment).

Secondary Outcome Measures :
  1. Percentage Change in Spleen Volume (cm3) [ Time Frame: baseline, week 12, week 30 ]
    Change of spleen volume from baseline at week 12 and week 30 as measured by magnetic imaging resonance (MRI) or computed tomography (CT).

  2. Percentage Change in Mean Pre-transfusion Hemoglobin by 6 Week Time Intervals [ Time Frame: baseline, weeks 0 - 30 ]
    Change from baseline in pre-transfusion hemoglobin levels

  3. Percentage Change in Spleen Length (cm) Below the Left Coastal Margin [ Time Frame: baseline, weeks 1,2,3,4,6,12,18,24,30 ]
    Change of spleen length from baseline over time measured by palpitation by time

  4. Pharmacokinetics (PK) Parameter of Cmin [ Time Frame: week 2, week 12 ]
    C min of INC424 by actual dose administered from 10mg bid to 20mg bid. Plasma PK samples were collected at Day 15 (Week 2), and Day 85 (Week 12). Cmin was collected immediately prior to dosing. n= number of patients with valid PK samples as per definition of the PK analysis set.

  5. Pharmacokinetics (PK) Parameter of Cmax [ Time Frame: Day 1, Week 2 (Day 15), Week 12 (Day 85) ]

    Cmax (1h) of INC424 by actual dose administered from 10mg bid to 20mg bid. Plasma PK samples were collected at Day 1, Week 2, and Week 12. Cmax was collected within a +/- 1 hour post dose.

    n= number of patients with valid PK samples as per definition of the PK analysis set.
