Brief Summary:
In this 4-year extension study the safety, efficacy and and pharmacokinetics of deferasirox in regularly transfused pediatric patients with β-thalassemia major was assessed. Patients who successfully completed the main 1 year trial (NCT00390858) were eligible to continue in this extension trial and receive chelation therapy with deferasirox for up to 4 years.

Drug Information available for: Deferasirox

Arm Intervention/treatment
Experimental: Deferasirox
Initial dose of 10 mg/kg, dose modifications of ± 5 or 10 mg/kg were based on participant response.
Drug: Deferasirox
Deferasirox in children from 1 to 18 years old was given orally once daily, 30 minutes prior to breakfast. An initial daily dose of 10 mg/kg was used during the 1-year core study. In this 4-year extension study dose modifications of ± 5 or 10 mg/kg were based on safety parameters and on increasing or decreasing Liver Iron Concentration (LIC), and serum ferritin. Deferasirox was available as 125 mg, 250 mg and 500 mg tablets.
Other Name: ICL670

Primary Outcome Measures :
  1. Participants With Adverse Events by Primary System Organ Class (SOC) [ Time Frame: 4 year extension + core 1 year ]
    Safety parameters were measured by the number and type of adverse events (AEs). An adverse event is any untoward medical occurence in a patient administered a medicinal product that does not necessarily have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign ( for example, an abnormal laboratory finding), symptom or disease temporally associated with the use of the medicinal product, whether or not this is associated with the use of this medicinal product.

  2. Change in Liver Iron Concentration (LIC) [ Time Frame: Baseline of Core Study to End of Extension Study, up to 5 years. ]
    Change in Liver Iron Concentration [LIC] measured by means of SQUID (Superconducting Quantum Interference Device). LIC is expressed in milligrams of iron per gram of liver dry weight (mg Fe/g dw)

Secondary Outcome Measures :
  1. Total Body Iron Elimination (TBIE) Rate (mg/kg/Day) [ Time Frame: Baseline of Core Study to End of Extension Study, up to 5 years ]
    Total Iron Body Elimination (TBIE) Rate [mg/kg/Day] was calculated for each patient based on SQUID ( Superconducting Quantum Interference Device) results.

  2. Relative Change in Serum Ferritin Level [ Time Frame: Baseline of Core Study to Extension 18 months, up to 2.5 years. ]
    Serum levels were drawn at the baseline of the Core Study up to 18 months of the Extension Study. Levels were analyzed for serum ferritin measured in micrograms per Liter. Relative change (%) in serum ferritin level was assessed from Baseline to Extension 18 months. Relative Change = 1 - (Change in ferritin level from Baseline/Baseline level) x 100.
