The emphasis will be on clinical trials that help identify optimal therapy. Therapeutic trials may involve investigational drugs, drugs already approved but not currently used, and drugs currently used.", "DetailedDescription"=>"BACKGROUND:\n\nCooley's anemia (beta-thalassemia major, hereafter referred to as thalassemia) is a severe, inherited blood disorder characterized by a quantitative defect in the synthesis of the beta chain of hemoglobin caused by any 1 of more than 100 known mutations in and around the beta globin gene cluster. The disease is characterized by severe anemia beginning in the first 6 to 12 months of life. If untreated, the life expectancy is less than 5 years of age. Chronic red blood cell transfusions to maintain hemoglobin levels between 9 and 11 gm/dl (\"hypertransfusion\") alleviate the anemia and partially suppress erythropoiesis. The regular administration of red blood cells also improves growth, delays or prevents enlargement of the liver and spleen, and prevents the development of bone abnormalities that cause fractures as well as disfiguring changes known as Cooley's facies. Transfusions carry risks of alloimmunization, iron overload, and blood-transmitted infections. In the absence of effective iron chelation therapy, iron overload leads to numerous complications, including delayed or absent sexual development, diabetes mellitus, cirrhosis, cardiac arrhythmias, and congestive heart failure. Nonchelated or poorly chelated patients usually die of heart disease by 20 to 30 years of age.\n\nThe addition of chelation therapy with deferoxamine (DFO) to the treatment of Cooley's anemia has dramatically improved the outcome for affected patients. With regular chelation therapy, the accumulation of excessive iron can be prevented. Studies have demonstrated that well-chelated patients have normal or only modest increases in liver iron, improved growth, sexual development, and most importantly, a markedly reduced chance of developing iron-induced heart disease.\n\nIn the past few years, several new approaches to the treatment of thalassemia have included marrow or stem cell transplantation; the use of young red blood cells (\"neocytes\") for transfusion; maintenance of a higher pretransfusion hemoglobin level; new iron chelators; and the use of drugs such as hydroxyurea, erythropoietin, and butyrate compounds.\n\nIt is recognized that even with a clinical network, the number of patients with Cooley's anemia who can be enrolled in a research protocol is likely to be small. Therefore, although a randomized clinical trial may be the preferred way of assessing the clinical benefits of a new therapy, it may not be feasible in some instances, even using biomarkers or other surrogate outcome measures. Depending upon the specific questions being addressed, other study designs might be appropriate. These might include pre- and post-treatment assessment or historical control studies. In all cases, the proposed design, including sample size, would be evaluated by the Protocol Review Committee.\n\nThere is an urgent need to evaluate new and existing therapeutic approaches for persons with thalassemia and to disseminate the findings to health care professionals, patients, and the public. There are several reasons why a thalassemia clinical research network will accelerate clinical research and meet this need. The highly variable and sometimes complicated clinical manifestations of thalassemia often make it difficult to accumulate a large number of comparable patients in one center. Furthermore, uniformity in treatment protocols may reduce the number of patients needed at each clinical center. Also, the TCRN mechanism will help pool the necessary clinical expertise and administrative resources to facilitate the conduct of multiple and novel therapeutic trials in a timely, efficient manner. This, in turn, would promote rapid dissemination of research findings to health care professionals.\n\nDESIGN NARRATIVE:\n\nThe network was originally funded in 2000 and has been extended through June 2010 to perform interventional clinical trials in key areas of thalassemia care. Two major trials are proposed: First, a randomized, controlled trial to examine the effect of DFO alone versus DFO plus deferiprone on cardiac disease due to transfusional iron overload; second, a randomized trial of arginine versus sildenafil for pulmonary hypertension, an important problem in thalassemia intermedia and other hemolytic states. Goals are to provide an infrastructure for development, launch, and prompt completion of small, innovative trials in thalassemia and to improve assessment of phenotype and clinical outcomes in thalassemia to facilitate current and future clinical trials. This will be accomplished by two studies: The Thalassemia Longitudinal Cohort (TLC) study and the Iron Burden Study, which is a detailed study of iron-related organ damage comparing measures of iron burden in the heart, liver, and pancreas to outcomes of iron-related organ dysfunction. Combined with the clinical trials and the ability to perform detailed genotype/phenotype correlations, these improved phenotype and outcome measures are powerful tools to enhance knowledge about thalassemia clinical care.
