10 Clinical Trials for Various Conditions
This single-arm, open-label, multi-center study enrolled 65 patients from approximately 20 centers. All patients who met the study criteria and were taking, beginning or resuming treatment with Deferasirox were allowed. The study will began with a one month run-in phase, where all patients were instructed to take Deferasirox according to their physician's prescribing information.
The prevalence of liver steatosis, steatohepatitis, fibrosis, and hemosiderosis in overweight and obese US Military dependent pediatric patients using MR Elastography and Quantitative MRI
The purpose of this multi-site research is to validate a rapid magnetic resonance based confounder-corrected R-2 mapping method as a quantitative imaging biomarker of liver iron concentrations.
The purpose of this study is to validate magnetic resonance imaging as a biomarker of hepatic iron concentration (HIC). Excessive accumulation of iron in the body is highly toxic, specifically in the liver. Accurate, non-invasive assessment of HIC is needed for diagnosis, quantitative staging and treatment monitoring or hepatic iron overload.
A 1-year randomized Phase II core trial was conducted to investigate the efficacy of deferasirox in regularly transfused patients with β-thalassemia and other rare chronic anemia 2 years of age and older. Patients who successfully completed the main trial may continue in the extension trial to receive chelation therapy with deferasirox for up to 3 years. Extension was prolonged to 4 years. The objective of this study is to assess the long-term safety and efficacy of deferasirox in these patient groups.
Hypothesis: The investigators suspect that significant degrees of iron overload in subjects with SCD result in decreased red cell survival, abnormal endothelial function and markedly dysregulated autonomic function. Furthermore, the investigators anticipate that the magnitude of these effects is proportional not only to the magnitude of total body iron stores but also to the duration of exposure to the high iron levels in tissues. Primary objective To determine if red cell survival as assessed by 51Cr red cell survival analysis, hemoglobin level, reticulocyte count, lactic acid dehydrogenase, and plasma hemoglobin in sickle cell patients is related to the degree of iron overload. Secondary objective(s) 1. Determine if the magnitude of endothelial-dependant vasodilation is related to The degree of iron overload. 2. Determine if the degree of change in cardiac beat to beat variability in response to hypoxic exposure or to cold exposure ("cold-face-test") is related the magnitude of iron overload. The primary measure of iron overload will be MRI determination of liver iron concentration.
The purpose of this study is to determine if the new orally active iron chelator, ICL670, is as safe as deferoxamine in preventing accumulation of iron in the body while a patient is undergoing repeated blood transfusions.
The safety, tolerability, effects on liver iron concentration and pharmacokinetics of ICL670 is studied in sickle cell disease patients with transfusional hemosiderosis.
The purpose of this open-label, non-comparative, multi-center protocol was to further evaluate safety and to provide treatment with ICL670 to patients who had or were at risk of life threatening complications due to transfusional iron overload with a documented inability to tolerate any of the commercially available iron chelators due to severe toxicity rendering continued therapy either impossible or hazardous. Patients who were also ineligible for all on-going registration trials with ICL670 were included in the study. In exceptional cases, patients with a degree of iron overload which was not immediately life-threatening and who were ineligible for the registration trials were also enrolled provided they had a well-documented, sound justification for alternative chelation therapy.
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.
