NCT00805701
Avodart (dutasteride) reduces the male hormone (DHT) that leads to prostate growth and stimulates cancerous growth. Avodart is currently approved by the FDA to treat men with symptoms of an enlarged prostate. Avodart works by reducing DHT and prostate size; therefore, the drug may be useful in improving lower urinary tract symptoms (LUTS) such as frequency, urgency, weak stream, and urination difficulty (dysuria), among others, in men with prostate cancer. Avodart may be effective in men with prostate cancer who are being treated with hormonal therapy with one injection of Zolodex (goserelin) followed one month later with a trans-urethral incision of the prostate (TUIP), and three months after that, seed implantation (SI) of the prostate. The purpose of this study is to test whether Avodart (dutasteride) is effective on LUTS and dysuria in men with localized prostate cancer being treated with single-dose goserelin, TUIP, and interval SI.
NCT00329238
The general aim of this study is to determine the comparative safety and efficacy of dabigatran etexilate administered orally and warfarin (International Normalized Ratio (INR) of 2.0-3.0) for the long-term treatment and secondary prevention of symptomatic venous thromboembolism in patients who have been successfully treated with standard doses of an approved anticoagulant for three to twelve months for confirmed acute symptomatic Venous Thrombo-embolism.
NCT01542788
This multicenter study was to evaluate subjects with chronic genotype 2 or 3 HCV infection who were interferon (IFN) ineligible, IFN intolerant or unwilling to take IFN. Participants were randomized in a 3:1 ratio to receive sofosbuvir (SOF)+ribavirin (RBV), or placebo to match SOF+placebo to match RBV. Randomization was stratified by presence/absence of cirrhosis. Approximately 20% of participants may have had evidence of cirrhosis at screening.

NCT01817296
Klinefelter syndrome occurs in 1 in 600 males and is a common cause of infertility in men. It appears scar tissue forms in these boys' testicles, leading to progressive destruction over their lifetimes. Advanced reproductive technology can be used to surgically retrieve sperm from these individuals, but these methods have a 50% failure rate in adult Klinefelter patients. Younger men have higher success rates, suggesting that adolescence and young adulthood may be the best time to extract sperm, but these techniques have not been studied in Klinefelter patients younger than 26 years of age. Additionally, there is currently no way to predict which Klinefelter patients will have success with these methods and which of them will not. This trial will explore sperm extraction in Klinefelter syndrome in an age range (12-25 years) that has never been studied, with the ultimate hope of improving the potential for fertility in these patients. The specific goals of this study are to determine the ideal age for sperm retrieval in Klinefelter patients and to establish factors that can be used to predict which of these patients will have a higher likelihood of success with advanced reproductive technology. The hypothesis is that younger Klinefelter patients will have higher sperm retrieval rates.
NCT00119262
This phase II trial is studying how well giving bevacizumab together with combination chemotherapy works in treating patients who have undergone surgery for breast cancer that has spread to the lymph nodes. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with more than one chemotherapy drug (combination chemotherapy), may be a better way to block tumor growth.
NCT00879229
Ambrisentan is an endothelin receptor antagonist used for the treatment of pulmonary hypertension (PH). Based on research suggesting a role for endothelin-1 in the pathogenesis of idiopathic pulmonary fibrosis (IPF) and the poor prognosis for patients with IPF who are also diagnosed with PH, this study was designed to evaluate the effectiveness and safety of ambrisentan in that patient population.
NCT01190085
Only a few medications are approved for the treatment of alcohol dependence and there exists a substantial need for discovering ways to provide more effective treatments. Accordingly, identifying new potential neuropharmacological targets in the treatment of alcohol dependence represents a high priority in public health. Ghrelin is a 28-amino acid peptide acting as the endogenous ligand for the growth hormone secretagogue receptor (GHS-R). Ghrelin was first isolated from the stomach, but a central hypothalamic production of ghrelin has also been demonstrated. Ghrelin plays a key role in the regulation of appetite. Consistent with the common neurobiological substrates for control of food and alcohol consumption, preclinical investigations suggest that ghrelin plays a role in the neurobiology of alcohol dependence, thus representing a new potential neuropharmacology target. In keeping with the preclinical studies, human investigations showed that alcohol consumption affects blood ghrelin levels and that blood ghrelin levels significantly and positively correlate with craving measurements in alcohol-dependent individuals. The effects of exogenous ghrelin injected intravenous (i.v.) in alcohol-dependent individuals, however, have never been investigated. The current project proposes a randomized double-blind placebo-controlled 3-group between-subject laboratory study aimed at investigating the effects of exogenous ghrelin i.v. on non-treatment seeking alcohol-dependent subjects in terms of urges to drink, attention to cues and related psychophysiological measures. This project has the goals to: i) conduct an alcohol laboratory study testing the role of ghrelin i.v., therefore demonstrating the feasibility of such a study and the safety of ghrelin i.v. when administered to alcohol-dependent individuals; and ii) explore the effects of ghrelin i.v. on alcohol craving assessed under controlled conditions, such as a cue-reactivity (CR) experiment. This study will address whether alcohol craving is affected when ghrelin levels are modified acutely via a ghrelin i.v. injection. Given the crucial need to expand our understanding of the underlying neurobiology of alcoholism, this study potentially will lead to identify new targets for the development of pharmacological treatments that may improve interventions for alcohol dependent individuals.

NCT00949286
The study is designed to determine the long term, post trial effects of the two interventions studied in ADVANCE (routine blood pressure lowering with perindopril-indapamide as compared with placebo and intensive gliclazide-MR based glucose control as compared to standard guideline based glucose control) in individuals with type 2 diabetes at high risk of cardiovascular events. The long term, post randomization effects of the two study interventions will be investigated separately as they were for the main trial. This study will clarify and quantify the long-term, post trial (often referred to as legacy) effects of these two interventions in a broader population of patients with type 2 diabetes from high and low to middle income countries, and in the setting of comprehensive cardiovascular risk factor treatment. With the ADVANCE trial infrastructure and surveillance system already in place, the implementation of extended follow-up will be feasible. The conclusions of this follow up study will have profound clinical implications for the care of patients with type 2 diabetes around the world.
