Transfusional Iron Overload Clinical Trial
Official title:
A 4-year Extension to a Phase II a Multicenter Study Evaluating Long-term Safety, Tolerability, Pharmacokinetics and Effects on Liver Iron Concentration of Repeated Doses of 10 mg/kg/Day of Deferasirox in Pediatric Patients With Transfusion Dependent β-thalassemia Major.
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.

Primary | Participants With Adverse Events by Primary System Organ Class (SOC) | 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. | 4 year extension + core 1 year | No |
Primary | Change in Liver Iron Concentration (LIC) | 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) | Baseline of Core Study to End of Extension Study, up to 5 years. | No |
Secondary | Total Body Iron Elimination (TBIE) Rate (mg/kg/Day) | Total Iron Body Elimination (TBIE) Rate [mg/kg/Day] was calculated for each patient based on SQUID ( Superconducting Quantum Interference Device) results. | Baseline of Core Study to End of Extension Study, up to 5 years | No |
Secondary | Relative Change in Serum Ferritin Level | 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. | Baseline of Core Study to Extension 18 months, up to 2.5 years. | No |
Secondary | Relative Change in Serum Transferrin Level | Serum Levels were drawn at Baseline of the Core Study and up to 18 months in the Extension Study. Serum was analyzed for transferrin levels measured as grams per Liter. Relative change (%) in serum transferrin level was assessed from Baseline to Extension 18 months. Relative Change = 1 - (Change in transferrin level from Baseline/Baseline level) x 100. | Baseline of Core Study to Extension Study 18 months , up to 2.5 years | No |
