Filter by:The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics following single oral and multiple oral doses BMS-791325 in healthy Japanese subjects.
The purpose of this study is to investigate the differences of genotypes of hepatitis B and hepatitis C in Taiwan.
The purpose of this study is to test the hypothesis that clemizole hydrochloride is safe and well tolerated when administered to subjects who are infected with hepatitis C virus and have not yet received treatment. This study will also examine how the virus and body respond to clemizole hydrochloride.
Treatment of patients with chronic hepatitis C infected with genotype 1 hepatitis C virus (HCV) consists of combined peginterferon/ribavirin for 48 weeks. Approximately 50% of patients experience sustained virological response which equals cure. All other patients either do not respond or experience recurrence of HCV virus and chronic hepatitis. Important predictors of successful treatment are sustained dosing of both peginterferon and ribavirin. With regard to the latter, clinical evidence indicates that higher ribavirin doses may in fact even improve treatment outcome. However, high ribavirin doses cause hemolytic anemia which require dose reductions. Recent clinical experience show that erythropoetic growth factors, including erythropoetin, can counteract hemolytic anemia caused by antiviral treatment in chronic hepatitis C patients. Therefore, the current trial aims to test whether higher ribavirin doses adapted to a target plasma concentrations instead of a weight-based dosing result in better healing rates, and whether ribavirin-associated hemolytic anemia can be compensated by concommitant erythropoetin treatment. Using a randomized, controlled, open-label design, the investigators hypothesize that patients with high ribavirin doses adapted to plasma levels experience better viral clearance than patients treated with standard weight-based ribavirin doses. In addition, the investigators hypothesize that erythropoetin treatment will counteract hemolytic anemia induced by ribavirin thereby allowing maintenance of target plasma concentrations without ribavirin dose reductions.
This study will provide vaniprevir 600 mg or 300 mg twice daily in combination with pegylated interferon (peg-IFN) and ribavirin (RBV) to participants with chronic hepatitis C virus (HCV) infection who did not achieve viral eradication while participating in a prior vaniprevir clinical trial (MK-7009-004, NCT00518622; MK-7009-007, NCT00704405; MK-7009-009, NCT00704184; and MK-7009-029, NCT00954993).
This 2 arm open-label study will assess the safety and tolerability of combination treatment with Peginterferon alfa (Pegasys) and Ribavirin (Copegus) in patients with chronic hepatitis C. Patients will be assigned to receive Peginterferon alfa (Pegasys) 180 mcg sc once a week and Ribavirin (Copegus) 800 - 1200 mg po daily for either 24 or 48 weeks. Allocation to the treatment arms is to the discretion of the investigator (mainly according to genotype). Adverse events will be monitored throughout the study and hematologic parameters every 2 weeks and twice during the 24-week follow-up.
The purpose of this study is to examine the safety, tolerability and pharmacokinetics of increasing oral doses of TMC435350 after single and repeated dosing, followed by an open label repeated dosing session in 6 HCV genotype1 infected patients.
This study will assess the rates of Sustained Virological Response following anti-viral therapy with Peg-Interferon plus Ribavirin in patients that have been liver transplanted with recurrent Hepatitis C and treated with Neoral or tacrolimus.
The purpose of this study is to investigate the effect of steady-state telaprevir (TVR) 750 mg q8h (3 times a day, every 8 hours) on the steady-state pharmacokinetics of escitalopram 10 mg q.d. (once a day), and vice versa. Steady state is a term which means that the drug has been given long enough so that the plasma concentrations will remain the same with each subsequent dose. TVR is being investigated for the treatment of chronic hepatitis C virus (HCV) infection. Pharmacokinetics (pk) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.
Hepatitis C is the most common reason for liver transplantation in the United States and affects nearly 4 million Americans. Treatments for hepatitis C are available but are poorly tolerated and are not always effective. Morbidity and mortality from hepatitis C are related to the development and progression of hepatic fibrosis to cirrhosis and end stage liver disease. Efforts to block progression of liver disease would thus result in prevention of morbidity and mortality as well as costs incurred by the health system in the care of these conditions. Scar tissue in the liver is secreted by a type of cell, called the stellate cell, in an activated state. This cell carries a receptor for angiotensin, a hormone, when activated. If this receptor is blocked, the cell becomes inactive and does not participate in scar tissue formation. Thus, we hypothesize that using a drug such as candesartan, which blocks angiotensin receptors, should result in less scar tissue formation in the livers of patients with hepatitis C.
