Study Details

Study Description

Brief Summary

This is a clinical research study in patients who have iron overload in the heart due to chronic blood transfusions.

The study will have 2 treatment groups and will compare the safety and efficacy of chelation therapy with a medicine called deferasirox (ICL670) with another medicine called deferoxamine (DFO). The study is aimed at finding out which of the two medicines is the best for treating iron overload in the heart.

Patients will be treated for 12 months (core study phase). Patients who complete the core study phase will be offered to continue their study treatment in a 12 months extension phase. During the core and extension, the effects of treatment on iron overload in the heart and the liver will be evaluated using specific magnetic resonance imaging (MRI) assessments.

    Primary Outcome Measures

    1. Core Study: Change From Baseline in Myocardial T2* (Magnetic Resonance T2-star (T2*) Technique for the Measurement of Tissue Iron) After 12 Months Treatment [12 Month]

      Non- inferiority in efficacy of deferasirox compared to deferoxamine (DFO) in treating cardiac iron overload as measured by T2*. A non-inferiority margin of 0.9 (90%) was applied. Due to limitations in performing heart biopsies, T2* (T2 star), a Magnetic Resonance (MR) relaxation parameter expressed in milliseconds, as is an important tool to noninvasively quantify cardiac iron concentration. Studies have shown that myocardial T2* evaluations may predict cardiac events, e.g., impaired (<56%) left ventricular ejection fraction (LVEF) is prevalent among patients with low T2*: found in 62% of patients with T2*<8 ms; 20% with T2* of 8-12 ms; and in 5% with T2* >12 ms (Tanner 2006)

For trough concentration assessments, a 2-mL blood sample was to be taken on arrival at the study site, i.e. prior to the patient receiving the daily deferasirox dose (pre-dose blood sample). A second 2-mL blood sample was to be taken 2 hours later (post-dose sample). At all other visits (Visits 3 - 14), a pre-dose sample was to be taken. For PK profile assessments, 3 blood samples were taken after 1, 2, and 4 hours post-dose in addition to the 2-mL pre-dose

    Title Core Study: Single and Repeated Dose Pharmacokinetics of Deferasirox, Maximum Plasma Concentration (Tmax)
    Description The plasma level of deferasirox (ICL670) obtained in this study was summarized descriptively. Plasma concentration was plotted by patient and by visit. Descriptive statistics included the mean, median, SD, and CV, min and max. deferasirox pharmacokinetics (PK) trough levels over the 12 months of treatment and obtained PK profiles for the 40 mg/kg/day deferasirox dose, time to reach maximum plasma concentration (Tmax)
    Time Frame 12 Month
