History of Changes
  Purpose

Because patients with beta-thalassemia are unable to actively eliminate iron from the body, toxic and eventually lethal levels of iron can accumulate as a result of repeated blood transfusions. This study will evaluate the efficacy, safety and tolerability of deferasirox.


Condition Intervention Phase
Beta-Thalassemia
Hemosiderosis
 Drug: deferasirox
 Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study

Primary Outcome Measures:
  • Liver Iron Concentration (as measured by biopsy) [ Time Frame: at baseline and after 1 yeor of ICL670 treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Iron balance, i.e. Total Body Iron Excretion (based on the iron influx as determined by the amount of red cells transfused and the change in total body iron (TBI) stores) [ Time Frame: after 1 year of ICL670 treatment ] [ Designated as safety issue: No ]
  • Putative surrogate markers such as serum ferritin serum iron, serum transferrin and transferrin saturation [ Time Frame: monthy assessments for 1 year ] [ Designated as safety issue: No ]
  • Adverse events [ Time Frame: during 1 year ICL670 treatment ] [ Designated as safety issue: Yes ]
  • hematology and biochemistry, urinalysis [ Time Frame: monthly assessments for 1 year ICL670 treatment ] [ Designated as safety issue: Yes ]
  • ECG and Echocardiography [ Time Frame: 6-monthly for 1 year ICL670 treatment ] [ Designated as safety issue: Yes ]

Enrollment: 252
