Filter by:A prospective, mono-center, interventional study evaluating the effect of one year initial care by hygieno-dietary advices with or without Phlebotomy on glycemia after at least 5 years in Patients with dysmetabolic iron overload syndrome
Safety, tolerability, and acceptability of twice-daily dosing with deferiprone delayed-release (DR) tablets in patients with systemic iron overload.
This study is looking at the effects of giving early treatment of deferiprone to young children with beta thalassemia who have started receiving regular blood transfusions but have not yet reached the criteria for starting on iron chelation therapy. Half the patients in the study will receive deferiprone, and the other half will receive placebo, for up to 12 months.
Dysmetabolic iron overload syndrome and genetic hemochromatosis are frequent causes of iron overload. Polyphenols are efficient iron-chelators. Investigator hypothesize that polyphenol supplementation can reduce iron absorption in iron overload disease. Iron absorption can be studied by the area-under-the-curve of serum iron after iron oral loading. The primary outcome is the decrease of post-prandial serum iron after rich-iron meal, due to polyphenol supplementation.
This study is a Phase 2 multicenter, randomized, placebo controlled, single-blind study. The primary objective of the study is to compare the effect of weekly dosing of LJPC-401 (synthetic human hepcidin) versus placebo on transferrin saturation (TSAT) in an adult hereditary hemochromatosis patient population.
This study employed a prospective, single-arm, global multi-center interventional open-label, non-randomized design to identify and assess safety profile of the crushed deferasirox FCT when administered up to 24 weeks in pediatric patients aged ≥2 to <6 years with transfusional hemosiderosis. The study was designed to enroll a minimum of 40 patients. Forty-four patients were treated and analyzed.
Peripheral blood mononuclear cells (PBMC) and platelets could be interesting ex vivo models to study brain diseases. Indeed, there is no access to neurons from patients. However, PBMC can exhibit different physiopathological mechanisms that are ubiquitous (i.e. oxidative stress, mitochondriopathy with energy metabolism, inflammation, protein folding, iron metabolism and programmed cell death ...). The platelets are pivotal in the healing system with large range of growth factors. A new therapeutic concept of conservative iron chelation with deferiprone for neuroprotection is under development. The action of deferiprone on the different mechanisms and notably the oxidative stress are to obtain from a collection of PBMC and platelets from patient having Parkinson's disease and Amyotrophic lateral sclerosis and healthy controls to study ex vivo. PBMC and platelets will be stored for future analyses.
Extend evaluation of deferasirox film-coated tablet (FCT) formulation
the aim of this study is to evaluate the effect of Spirulina compared to Amlodipine on cardiac iron overload and cardiac functions in multi-transfused children with beta thalassemia major
Heart failure from myocardial iron deposition is a severe complication for patients with hematological disorders who need repeated blood transfusions. Increased cardiac iron content impacts the contractility of cardiomyocytes and can also lead to myocarditis, pericarditis, and arrhythmias. The severity of cardiac dysfunction depends on the amount of iron deposited in the myocardium. Cardiovascular magnetic resonance (CMR) imaging is used as noninvasive method to evaluate the amount of iron in the heart. Myocardial T2* value has been shown to correlate well with biopsy-derived iron concentration in the heart, and myocardial T2* values less than 20ms (indicating elevated iron) were found to be associated with LV dysfunction and improve in concert with LV function during recovery. The majority of the recent studies about myocardial iron overload and the effect of iron chelation therapy were focused on patients with transfusion-dependent hematological disorder, especially beta-thalassemia major. The objective of this 3-year project is to evaluate myocardial iron deposition in patients with heart failure, induced by variable causes. With myocardial T2* imaging, the investigators will analyze the decreased signal intensity in the ventricular septum and quantitatively acquire the T2* value as marker for myocardial iron deposition. The first year is a cross-sectional study. The investigators aim to compare the severity of myocardial iron deposition of normal subjects and that of stable HF patients in recovery with normal or impaired ejection fraction (EF). Total 60 subjects will be enrolled, with 20 subjects in each group. In the 2nd and 3rd years, the investigators plan a prospective longitudinal study of 40 subjects. Enrolled patients will be evaluated with cardiac T2* imaging at three time points, i.e., disease onset, 6 months and one year after treatment, and will be followed up until the end of this project (1.5~3-year follow up). In total 120 MR scans will be performed in the 2nd and 3rd years. The presence and severity of myocardial iron deposition will be correlated with the disease course, patient biochemistry data and clinical outcome.
