Filter by:The purpose of this study is to investigate the effects of iron chelation using deferasirox in low and INT-1 risk (referring to the international prognostic scoring system, IPSS) MDS patients who show signs of iron overload due to repeated blood transfusions. This trial is not recruiting patients in the United States.
Certain percentage of MDS patients develop iron overload. Iron is known to participate in intracellular reactions that generate free radicals, inducing oxidative stress and apoptosis, which was found to be increased in MDS patients and consequently resulted in ineffective hematopoiesis. The aim of this study is to evaluate the antioxidant effect of the oral iron chelator Deferasirox -Exjade in low risk MDS patients with iron over load by evaluating changes in several oxidative stress parameters Certain percentage of MDS patients develop iron overload.
The purpose of this trial is to evaluate changes in cardiac iron as measured by MRI T2* in beta-thalassemia patients with deferasirox treatment.
Iron excess is increasingly regarded as an important cofactor in the morbidity attributed to many disorders. Assessment of body iron stores by measurement of serum ferritin concentrations has poor specificity and the most reliable method is histological or biochemical assessment from a liver biopsy. Because liver biopsy is an invasive procedure, imaging methods have been developed to detect and quantify hepatic iron content. The aim of the study is to use a simplified magnetic resonance imaging (MRI) technique to quantify simultaneously iron and fat contents in the liver and to compare the results to the quantification obtained biochemically.
Brief Summary: This study was designed to explore a safe dose and characterize the preliminary safety and efficacy of ICL670 in adult patients with previously documented history of homozygous C282Y.
In this 4-year extension study the safety, efficacy and and pharmacokinetics of deferasirox in regularly transfused pediatric patients with β-thalassemia major was assessed. Patients who successfully completed the main 1 year trial (NCT00390858) were eligible to continue in this extension trial and receive chelation therapy with deferasirox for up to 4 years.
A 1-year randomized Phase IIa core trial followed by a prolongation of 5 to 9 months was conducted to investigate the efficacy and safety of deferasirox in patients aged ≥ 18 years with transfusion-dependent iron overload. The objective of this extension study is to assess the long-term safety of deferasirox and to provide treatment in patients with transfusional iron overload.
The aim of this study is to evaluate the effect of muscular exercise on iron metabolism in healthy volunteers. Fourteen healthy male subjects will have to pedal on an ergocycle for 45 minutes, and urine and blood samples will be collected regularly to measure hemojuvelin, hepcidin, iron and transferrin levels.
Patients who have iron overload due to chronic blood transfusions and have developed heart failure or who are at high risk of heart failure because of the high levels of iron in their hearts, will be treated with deferiprone, an investigational drug, in combination with deferoxamine (Desferal). Some studies suggest that deferiprone may be better than deferoxamine in removing iron from the heart and improving heart function, and that using both drugs together may remove more iron. Participants would make a clinic visit for lab studies each week, and would continue to take deferiprone for as long as their physician feels it is useful in their care.
This is an open-label, non-randomized, multi-center trial designed to provide expanded access of deferasirox to patients with congenital disorders of red blood cells and chronic iron overload from blood transfusions who cannot adequately be treated with locally approved iron chelators.
