Active clinical trials for "Iron Overload"

Genetic disorders, such as thalassemia, can lead to iron overload and severe adverse health outcomes. In iron-loading thalassemia, iron overload is due to increased iron absorption. Iron accumulates in the body organs causing widespread damage. The standard treatment is iron chelation therapy and/or periodic phlebotomy to remove iron from the body; frequency of phlebotomy or chelation therapy is dependent on how quickly body iron stores accumulate. Polyphenolic compounds are very strong inhibitors of non-heme iron absorption, as they form insoluble complexes with ferrous iron in the gastrointestinal tract that cannot be absorbed. The investigators have recently shown in European subjects with hereditary hemochromatosis (another iron-loading disorder) that our newly-developed natural polyphenol supplement (PPS) that is rich in polyphenols, when taken with iron-rich meals or with an iron-fortified drink, reduces iron absorption by ~40%. Decreasing non-heme iron absorption in adults with iron-loading thalassemia could potentially lead to an extension of the time period between phlebotomies or chelation therapies, and therefore an improved quality of life. Therefore, in this stable iron isotope study, the investigators will study the effect the natural PPS on oral iron absorption from an iron-rich test meal or iron-fortified drink in Thai adults with iron-loading thalassemia.

This study is a Phase 2 multicenter, randomized, open-label, parallel-group study. The primary objective of the study is to evaluate the effect of LJPC-401 (synthetic human hepcidin) on iron levels in patients with transfusion-dependent beta thalassemia with myocardial iron overload.

This is an open-label study to assess the pharmacokinetics, safety, efficacy and tolerability of SSP-004184AQ. The study consists of two phases: the pharmacokinetic phase, using a single 16 mg/kg dose of SSP-004184AQ; and the chronic dosing phase, during which patients will receive an additional 48 weeks of SSP-004184AQ dosing. Two age groups will be studied: 6-<12, and 12-<18 years old. The study is designed to initially assess the pharmacokinetics and safety of SSP-004184AQ in older children (adolescents, 12-<18 years old) and then if deemed safe, in younger children (6-<12 years old).

The scientific rationale for this study is the evolving understanding that iron-induced tissue damage is not only a process of progressive bulking of organs through high-volumes iron deposition, but also a reactive iron species related "toxic" damage. Iron mediated damage can occur prior reaching high iron storage thresholds derived from thalassemia major setting, free toxic iron species being already present when transferrin saturation >60-70% (25); therefore a timely early adoption of iron chelation may be of benefit before overt iron overload is seen. Our hypothesis is that early and low dose DFX-FCT is better tolerated and is able to prevent iron accumulation and consequently tissue iron related damage, by consistently suppressing iron reactive oxygen species (NTBI and LPI). If this hypothesis is confirmed this approach could contribute to an improvement of clinical practice of patients managements. Additionally this approach might also be a contribute in preventing future iron overloaded related complication, in this already frail and co-treated patient population.

The objective of the study is to evaluate and compare the frequency and severity of GI adverse events in different dose administration regimens. The patient population consists of low or intermediate (int-1) risk myelodysplastic syndrome (MDS) patients with transfusional iron overload. The study patients are randomized to either a morning dose of 20 mg/kg/day deferasirox or an evening dose of the same. Patients are then followed up for 6 months for any GI events and are assessed using patient reported outcomes tools e.g. a patient diary.

Evaluated Exjade efficacy and safety in patients with aplastic anemia and transfusion-dependent iron overload, undergoing treatment programs of immunosuppressive treatment (Cyclosporine A) , in comparison with a group of patients undergoing treatment programs of immunosuppressive treatment (Cyclosporine A) without chelation therapy.

The purpose of this study is to assess safety and amount of the study drug in the blood after increasing doses of SP-420. The study will be conducted in patients with β-thalassemia.

Hypothesis: Deferasirox can be used as a therapeutic agent to deplete the liver, heart and bone marrow of excess iron in patients with iron overload caused by myelodysplastic syndrome (MDS) and hemochromatosis (HC. Assess the effect of new serum biomarkers (NTBI and hepcidin) and MRI as indicators of iron overload and their usefulness to monitor iron depletion treatment. Study the effect of iron overload and iron depletion on intracellular signal transduction, trace metals concentrations in serum and urine and markers of oxidative stress in blood cells and urine.

The purpose of this extension study is to evaluate SSP-004184AQ in patients with transfusional iron overload and to provide data on long term safety and efficacy. SSP-004184AQ is an iron chelator under development for chronic daily oral administration to patients with transfusional iron overload

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) Determine if the magnitude of endothelial-dependant vasodilation is related to The degree of iron overload. 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.
