Official Title  ICMJE A Randomized, Comparative, Open Label Phase III Trial on Efficacy & Safety of Long-term Treatment With ICL670 Compared to Deferoxamine in Beta-thalassemia Patients With Transfusional Hemosiderosis
Brief Summary The purpose of this study is to deterimine if the new orally active iron chelator, ICL670, is as effective and as safe as deferoxamine in preventing accumulation of iron in the body while a patient is undergoing repeated blood transfusions.
Detailed Description Patients who require repeated blood transfusions to live accumulate iron in the body as blood cells contain iron and there is no natural body mechanism to eliminate it. After a while the iron levels get high enough to be toxic to the body. The current therapy of choice is deferoxamine, which does a good job of removing excess iron, but is difficult to administer. Deferoxamine requires subcutaneous (under the skin) infusions over 4 to 8 hours nightly 3 to 7 nights per week. In addition to the need to wear an infusion pump nightly, adverse reactions around the site of the injection are frequent.
