Summary

Thalassemia major is a genetic disorder affecting hemoglobin synthesis, rendering individuals dependent upon lifelong blood transfusions. Consequently, iron overload occurs and patients have shortened life expectancy with the most common cause of death being heart failure. This trial tests whether the combination of traditional therapy (deferoxamine) with a newer drug (deferiprone) will prove more effective in removing cardiac iron than deferoxamine alone.

Detailed description

Thalassemia Major (TM) is a hereditary anemia resulting from a single gene defect that results in abnormal red cell production. The survival of affected individuals is dependent upon lifelong blood transfusions. Unfortunately, this causes total body iron overload, and 50% of the patients in the UK are dead by the age of 35. Approximately 70% of these deaths result from heart failure which results as a consequence of cardiac iron toxicity. A Cardiovascular Magnetic Resonance (CMR) technique (which exploits the fact that T2\* signal decay relates to tissue iron) developed at the Royal Brompton Hospital provides a non-invasive and reproducible assessment of cardiac iron. CMR therefore provides a very useful method to assess response to new treatments in this condition. Using cardiac T2\* as a primary endpoint, we will investigate whether the oral chelator, deferiprone in combination with traditional treatment (deferoxamine), is superior in removing cardiac iron as compared to deferoxamine alone. This trial will provide the first randomized controlled, double-blinded, evidence for the efficacy of combination treatment in TM.
