Active clinical trials for "Thalassemia"

Children with thalassemia may have high iron levels after receiving blood transfusions. These high iron levels can have damaging effects on the body, especially the heart. Conventionally only chelation therapy was given for prevention of iron buildup in the heart. However, current research has shown that another drug, amlodipine, also helps to slow down the deposition of iron in the heart. This study is designed to see if patients receiving amlodipine along with their regular chelation therapy have a slower rate of iron buildup in the heart when compared with patients who are receiving chelation only.

The improved long-term survival of thalassemia major (TM) patients has resulted in increased focus on the ability to preserve fertility. While the association of iron toxicity with vital organ dysfunction, heart and liver, has been extensively investigated, the correlation of reproductive capacity and extent of iron overload is not well understood. Despite remarkable progress in methodology for prediction of reproductive status and intervention for preserving fertility, implementation in thalassemia is lacking. The investigators hypothesize that iron toxicity to the anterior pituitary occurring in the process of transfusional iron loading is directly associated with a decline in gonadal function. The investigators expect pituitary MRI measurements of iron deposition as well as markers of oxidative damage to correlate with the functional studies of pituitary-gonadal axis performed in this study. This cross sectional study will examine the relation of pituitary iron deposition and pituitary volume; serum iron and oxidative stress measures, liver iron concentration (LIC), cardiac iron and chelation adequacy with pituitary and gonadal reproductive hormone levels (and spermatogenesis in adult male patients), in order to better define the association of iron burden and chelation patterns with fertility potential, in thalassemia patients with iron overload. The study will assess whether the current chelation treatment regimens, in particular during the pubertal developmental age, are adequate for preserving fertility and could lead to improved chelation routines for preventing the high prevalence of compromised fertility. In addition, by utilizing state-of-the-art markers for fertility status, findings from this study may improve current methods for screening for hypogonadism and reproductive potential and allow earlier intervention. The investigators propose to examine 26-30 patients, 12 years and older, with measures of fertility potential, and correlate them to their current iron burden parameters and to the cumulative iron effect as indicated by past iron overload patterns and chelation history.

The aim of the study is to: Assess the pattern of glucose homeostasis in patients with B thalassemia . To detect early impairment in glucose metabolism and prediabetic state in B thalassemia patients using continuous glucose monitoring system. To study the prevalence and type of DM in B thalassemia patients. A comparative study of standard insulin therapy compared to insulin pump therapy in thalassemic diabetic patients will be done. The study will include screening of 200 children and adolescents who are regularly attending the Hematology Oncology Clinic and fulfilling the inclusion criteria for abnormalities of glucose homeostasis. A pilot study will be done on 15 patients with abnormal glucose tolerance which will include: A-Continuous glucose monitoring system (CGMS) : A glucometer will be given to each patient and will be asked to measure blood glucose before meals and snacks and record the valus in the CGMS for better calibration . B-Therapeutic intervention: Thalassemia patients who proved to have diabetes according to the ADA criteria will be subjected to • Insulin pump will be tried in each diabetic thalassemic patient versus conventional insulin therapy.

This research study is being done to assess the safety and effectiveness of isoquercetin to reduce levels of soluble P-Selectin in patients with sickle cell disease. Isoquercetin is a naturally occurring flavonoid-or vitamin. You will find quercetin and isoquercetin in fruits and vegetables. The names of the study drug involved in this study are/is: - Isoquercetin

To characterize the PK of deferasirox in pediatric β-thalassemia major patients aged from 2 to less than 6 years old, when administrated with a fixed starting dose of 20 mg/kg/day.

The purpose of this open-label study is to assess liver iron concentration using MRI imaging in subjects with beta-thalassemia when administered with either SPD602 or deferasirox for the treatment of chronic transfusional iron overload.

The primary purpose of this study is to determine the safety and tolerability of SLN124 for the treatment of non-transfusion-dependent (NTD) β-thalassaemia and low risk myelodysplastic syndrome.

The evaluation of efficacy is performed by laboratory monitoring of bone density and resorption markers and clinical monitoring of bone density improvement. This is a prospective, randomized, parallel group, single blind study of one year treatment with zoledronic acid every 6 months as compared to one year treatment with zoledronic acid every 3 months and to placebo every 3 months in patients with hemoglobin syndromes and risk of skeletal complications.

The purpose of this study is to test the safety and tolerability of SP-420 and it's efficacy in terms of lowering iron in subjects with Beta-thalassemia or other rare anemias who need regular blood transfusions.

The main purpose of this study is to evaluate the efficacy of 3 multiple doses of VIT-2763 as measured by the reduction in red blood cell (RBC) transfusion burden from Week 13 to Week 24, to identify the most efficacious and safe dose.
