Arm Description

All patients were treated with 10mg/kg/day deferasirox with dose adjustments after 4 weeks of treatment according to baseline Liver Iron Concentration (LIC).

Outcomes

Primary Outcome Measures

Absolute Change in Liver Iron Content (LIC) at 52 Weeks From Baseline
Absolute change in liver iron concentration measured by MRI from baseline after 52 weeks of treatment

Secondary Outcome Measures

Percentage of Participants With Baseline LIC>15 Achieving LIC<5 mg Fe/g dw
The percentage of participants with baseline LIC>15 mg Fe/g dw achieving an LIC <5 mg Fe/g dw during the study
Time to Achieving LIC <5 mg Fe/g dw
Time to achieving LIC <5 mg Fe/g dw for participants with baseline LIC>15 mg Fe/g dw during the study
Time From Target LIC of 3 mg Fe/g dw to the First LIC ≥5 mg Fe/g dw in the Follow up Period
Time from the target LIC <3 mg Fe/g dw to the first LIC ≥5 mg Fe/g dw in the follow-up period
Absolute Change in Health-related Outcomes Using Medical Outcomes Study Form 36 (SF-36v2)
The SF-36 is a self-administered questionnaire for adults (from 18 years of age) and contains 36 items which measure: Physical functioning, Role limitation due to physical health problems, Bodily pain, General health perceptions, Vitality, Social functioning, Role limitations due to emotional problems and General mental health . The higher values indicate a better evaluation of health. Range: 0 to 100 [0 (worst possible health state measured by the questionnaire) to 100 (best possible health state)].
Absolute Change in Health-related Outcomes Using the Pediatric Quality of Life Questionnaire (PedsQL™)
The PedsQL™ is a modular approach to measuring health-related quality of life (HRQOL) in children and adolescents. The 23-item PedsQL™ Generic Core Scales encompass the essential core domains for pediatric HRQOL measurement: 1) Physical Functioning (8 items), 2) Emotional Functioning (5 items), 3) Social Functioning (5 items), and 4) School Functioning (5 items). The Generic Core Scales are designed to enable comparisons across patient and healthy populations. The higher values indicate a better evaluation of health. Range: 0 to 100 [0 (worst possible health state measured by the questionnaire) to 100 (best possible health state)].
Absolute Change in LIC From Baseline Over Time
Absolute change in serum ferritin from baseline over time up to 260 weeks
Serum Ferritin (SF) vs LIC at Baseline and EOS (Week 260 + 30 Days Follow-up)
Correlation between serum ferritin and LIC is assessed using scatter plots with pearson correlation coefficient and simple linear model.
Correlation Analysis for Absolute Change in LIC and Serum Ferritin at Week 24 and EOS (Week 260 + 30 Days Follow-up)
Correlation for absolute change between LIC and serum ferritin was assessed using scatter plots with pearson correlation coefficient and simple linear model.
Absolute Change in LIC From Baseline After 52 Weeks of Treatment by Underlying Non-transfusion Dependent Thalassemia (NTDT) Syndrome
Absolute change in liver iron concentration measured by MRI from baseline after 52 weeks of treatment by underlying NTDT syndrome. The 4 underlying disease types: Beta-thalassemia intermedia (N =69), HbE beta-thalassemia (N = 24), Alpha-thalassemia intermedia (HbH disease) (N = 40), Other, specify (N = 1)
Absolute Change in Serum Ferritin From Baseline After 52 Weeks
Absolute change in serum ferritin from baseline after 52 weeks of treatment
PK Parameters: AUCtau
The pharmacokinetic parameter, AUCtau was determined using non-compartmental method(s) for deferasirox and its iron complex. AUC=area under the concentration-time curve during a dosing interval at steady state (amount × time × volume).
PK Parameters: Cmax
The pharmacokinetic parameter, Cmax, was determined using non-compartmental method(s) for deferasirox and its iron complex. Cmax (maximum/peak plasma drug concentration after drug administration)=amount × volume
PK Parameters: Tmax
The pharmacokinetic parameter, Tmax, may be determined using non-compartmental method(s) for deferasirox and its iron complex. Tmax=time to reach maximum/peak concentration following drug administration.
Plasma Pharmacokinetics (PK) Deferasirox Concentrations
Blood samples for PK evaluation were collected for a sub-group of patients. The patient had to have been on treatment without dose adjustment or treatment interruption (for any reason) for at least 4 consecutive days prior to scheduled PK sampling visit. If there was a dosage change or interruption within 4 days of the visit, no PK blood samples was collected, and an appropriate comment had to be made on the PK CRF page.
