NCT01058837
No clinical trial that has examined the role of implantable cardioverter defibrillator (ICD) therapy in the prevention of Sudden Cardiac Death (SCD) has provided outcome data for longer than a few years. The NHLBI sponsored and placebo-controlled Sudden Cardiac Death in heart Failure Trial (SCD-HeFT) conducted from 1997 to 2003 had the largest number of patients and the longest average follow-up at 45.5 months. This study changed the national reimbursement policy for ICD therapy and remains the reference point for all other ICD evaluations in patients with congestive heart failure from ischemic or non-ischemic systolic dysfunction. Despite the outcome, the role of ICD therapy in the management of patients with heart failure has been questioned because of four principal concerns: numbers needed to treat to save a life, lead integrity over time, the negative consequences of shock therapy, and the cost of therapy. The purpose of this trial is to track down the remaining patients for a one-time follow-up regarding key outcome data.
NCT00337662
The current study has been designed to address the significance of early onset of response prospectively in patients treated with an atypical antipsychotic.
NCT00691470
The purpose of this research study is to test an experimental drug ATI-5923 vs Coumadin. The study is intended to demonstrate ATI-5923 is superior to Coumadin for keeping INR values in the desired therapeutic range. Patients who require chronic anticoagulation with one or more of the following conditions are eligible for the study: atrial fibrillation or atrial flutter, prosthetic heart valve, venous thromboembolic disease, or history of myocardial infarction or cardiomyopathy will be enrolled.
NCT00002792
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining bone marrow or peripheral stem cell transplantation with chemotherapy may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus either bone marrow or peripheral stem cell transplantation in treating patients with myeloproliferative disorders.
NCT00003913
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of umbilical cord blood transplantation plus combination chemotherapy in treating patients who have hematologic cancer or nonmalignant hematologic disease.
NCT00003883
RATIONALE: Giving itraconazole or fluconazole may be effective in preventing infections in patients undergoing peripheral stem cell or bone marrow transplantation. It is not yet known whether itraconazole is more effective than fluconazole for preventing infections. PURPOSE: Randomized phase III trial to compare the effectiveness of itraconazole with fluconazole to prevent infections in patients undergoing peripheral stem cell or bone marrow transplantation.
NCT00360815
Background. Long-term microvascular and neurologic complications cause major morbidity and mortality in patients with insulin-dependent diabetes mellitus (IDDM). We examined whether intensive treatment with the goal of maintaining blood glucose concentrations close to the normal range could decrease the frequency and severity of these complications. Methods. A total of 1441 patients with IDDM -- 726 with no retinopathy at base line (the primary-prevention cohort) and 715 with mild retinopathy (the secondary-intervention cohort) were randomly assigned to intensive therapy administered either with an external insulin pump or by three or more daily insulin injections and guided by frequent blood glucose monitoring or to conventional therapy with one or two daily insulin injections. The patients were followed for a mean of 6.5 years, and the appearance and progression of retinopathy and other complications were assessed regularly.
NCT00006280
This study's primary goals are to test the safety and effectiveness of Tobramycin for Inhalation (TOBIr) in cystic fibrosis (CF) patients who are between 6 months and 6 years of age. This drug is an antibiotic that is inhaled into the lungs by the patient. It has already been studied and approved by the FDA for treatment of CF patients 6 years and older. Lung fluid will be examined for bacteria before and after the 28-day treatment. The amount of bacteria before and after treatment will be compared. This will indicate whether the antibiotic was effective in killing bacteria in the lungs. Once treatment begins, patients will be monitored every 2 weeks throughout the study (5 exams in 56 days). Half of the patients will receive TOBIr, half will receive a placebo (a substance that looks like TOBIr but contains no medication).
NCT00787111
This open-label research study will continue to monitor the safety of fluoxetine in children after their completion of a previous double-blind placebo controlled clinical study, with fluoxetine. The study will also look at the effect of fluoxetine on IQ (Intelligence Quotient) over an 18 month period.
NCT00212290
The purpose of this study is to examine the effects of treating insulin resistance on memory and attention, brain glucose utilization, and proteins in spinal fluid.
NCT00002707
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if chemotherapy given before surgery is more effective with or without docetaxel given before or after surgery for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy using doxorubicin and cyclophosphamide with or without docetaxel in treating women who have stage II or stage III breast cancer.

NCT00702819
Retinopathy of Prematurity (ROP) is a leading cause of blindness in children in developed countries around the world, and an increasing cause of blindness in developing countries. The retina lines the inside of the eye. It functions as "film" within the camera which is the eye. When an infant is born prematurely, the vascular network necessary to nourish the retina has not fully developed. As a consequence, in some infants abnormal vessels proliferate instead of the normal ones - a condition known as ROP. The abnormal vessels carry scar tissue along with them, and may lead to retinal detachment and blindness if the eye is not treated. The Multicenter Trial of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) Study demonstrated that ablation of the peripheral avascular retina reduced the risk of poor structural and visual outcome due to retinal distortion or detachment in ROP (1980's). The ablated retina is not functional and is not amenable to regeneration. Peripheral retinal ablation is not universally effective in fostering regression of ROP. This is particularly true for an aggressive form of ROP (aggressive posterior ROP, or APROP) which typically afflicts profoundly premature and infirm neonates. In this subset of infants, progression of ROP to bilateral retinal detachment and blindness occurs despite timely and complete peripheral retinal laser ablation. Rationale The development of ROP is largely dependent on vascular endothelial growth factor (VEGF). When an infant is born prematurely the relatively hyperoxic environment the baby is introduced to shuts down the production of VEGF. Retinal maturation is delayed. Subsequently, at a time when intraocular VEGF levels would normally be declining late in the third trimester of pregnancy, abnormally high levels of VEGF are seen due to large areas of avascular retina and associated tissue hypoxia. The availability of FDA-approved drugs for anti-VEGF treatment renders it possible to treat such eyes off-label. Available drugs include pegaptanib sodium (Macugen) for partial blockage of VEGF-A, or drugs such as ranibizumab (Lucentis) and bevacizumab (Avastin), which cause complete blockage of VEGF-A. As VEGF is required in the developing retina for normal angiogenesis, and our goal is not to penetrate tissue, but to block the excessive levels of VEGF trapped within the overlying vitreous which is responsible for the abnormal vasculature in ROP. For purposes of this study the investigators have chosen bevacizumab (Avastin), which will: a) attain complete blockage (vs. Macugen) of intravitreal VEGF-A, and; b) which is limited in its ability to penetrate tissues because it is a full antibody (vs. Lucentis, an antibody fragment specifically designed for better tissue penetration), and is more likely to restore VEGF homeostasis within the developing retina.
NCT00506584
The purpose of this study is to determine whether very low birth weight infants (less than or equal to 1250g or about 2 3/4 pounds) born prematurely fed a diet of only human milk and human milk-derived nutrition have better health outcomes than babies fed at least some formula (made from cow's milk)or formula-derived nutrition.
