About this study
Official title: A Multicenter, Randomized, Open-label Phase II Trial Evaluating Deferasirox Compared With Deferoxamine in Patients With Cardiac Iron Overload Due to Chronic Blood Transfusions
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Core Study: Change From Baseline in Myocardial T2* (Magnetic Resonance T2-star (T2*) Technique for the Measurement of Tissue Iron) After 12 Months Treatment
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)
Measured: 12 Month

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?
Core Study: Change From Baseline in Myocardial T2* (Magnetic Resonance T2-star (T2*) Technique for the Measurement of Tissue Iron) After 12 Months Treatment (time frame: 12 Month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00600938, which also lists 2 linked publications.
