Filter by:The purpose of this study is to investigate the effect of severe renal impairment or failure on the single-dose pharmacokinetics of telaprevir (TVR). Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. In addition, the effect of severe renal impairment on the total and unbound plasma concentrations of the sum of TVR and its R-diastereomer VRT-127394 will be assessed. (Diastereomers are substances whose chemical structures are mirror images of each other). Finally, the short-term safety and tolerability of TVR in participants with severe kidney disease will be determined. The results of this study will guide dose recommendations for TVR in subjects with kidney disease.
This study will assess the repeatability of Magnetic Resonance Elastography (MRE) in both healthy volunteers and Hepatitis C Virus (HCV)-infected patients with fibrosis and lay the groundwork for the validation of MRE as an alternative to liver biopsy.
According to the centres taking part in the ALHICE survey, the number of HIV-HCV co-infected women is currently decreasing. This drop was first noted in 2006 and persisted in 2007. What might have been considered a chance phenomenon during the first year (2006) was confirmed in the beginning of 2008. In view of this information, the investigators wished to ascertain the reality of this trend and to investigate its causes, by attempting to answer the following questions: - Has the prevalence of risk factors for HCV infection changed among the general population over the past 10 years? - Has the prevalence of risk factors for HCV infection changed among HIV/HCV co-infected women over the past 10 years? - Is the change in the number of co-infected women who gave birth during the past 10 years related to the prevalence of certain risk factors among this population? - Is the change in the number of co-infected women who gave birth during the past 10 years related to a decrease in certain risk factors for HCV infection among the general population? - Have changes in addictive behaviour among women of child-bearing age played a role in the decreasing number of HCV-contaminated children? Furthermore, follow-up data from HCV-infected children born during this period will provide information concerning the course of HCV infection. The objectives are to study trends in numbers of deliveries among HCV/HIV co-infected women as well as trends in risk factors for HCV infection among women of child bearing age and lastly to create a cohort of HCV infected children.
The purpose of this study is to determine the decline of virus in the blood and liver in patients treated with telaprevir, pegylated interferon and ribavirin. Fine Needle Aspiration (FNA) procedure will be used to repeatedly sample the liver to enhance the understanding of how the virus decays in the liver in response to treatment with anti-viral compounds and the measurement of the concentration of the drugs in the liver. FNA is an alternative procedure to core needle biopsy in its ability to repeatedly sample the liver with significantly reduced morbidity.
The purpose of this study is to evaluate the efficacy of 4 different regimens of TMC435 in combination with peginterferon alfa-2a (PegIFNα-2a) and ribavirin (RBV), defined as the proportion of patients with sustained virologic response at Week 72 (patients with undetectable plasma HCV RNA [less than 25 IU per mL undetectable] at the end of treatment and at Week 72), compared to the control group receiving PegIFN and RBV in combination with TMC435-matched placebo.
There is a distinct lack of published literature on the effect of combination treatment of PEG-interferon and ribavirin on post-renal transplantation hepatitis C virus (HCV) patients. Small case series have been published utilizing conventional interferon and/or ribavirin and the available data is extremely preliminary in nature. A small retrospective series of patients treated with Pegylated interferon and ribavirin published recently suggests that the treatment may be safe and efficacious. Unpublished reports from a few centers within Saudi Arabia also suggest a good safety profile and reasonable efficacy from this form of combination treatment. The investigators aim to prospectively study the safety and efficacy of PEG-interferon and ribavirin combination therapy in post-renal transplant HCV-infected patients. Towards this 40 patients with histological evidence of liver disease will be recruited and the efficacy of the above medications studied. The proposed study aims to evaluate the efficacy and safety of PEG-interferon and ribavirin combination therapy in the treatment of chronic HCV in renal transplant patients in a way that will allow management of such patients in an optimized manner.
The study evaluates safety and efficacy of vaniprevir (MK7009), when administered with Pegylated-Interferon (peg-IFN) and Ribavirin, in Japanese patients with Hepatitis C infection. The primary hypotheses are that 1.) the proportion of patients achieving rapid viral response (RVR) in one or more of the vaniprevir treatment groups is superior to that in the placebo group, when each is administered concomitantly with pegylated interferon (peg-IFN) α-2a and ribavirin; and 2.) vaniprevir at the studied doses is well tolerated compared with placebo, when each is administered concomitantly with peg-IFN α-2a and ribavirin for 28 days.
The proposed studies will examine the extent of pharmacokinetic and pharmacodynamic interactions between alcohol and various antiretroviral therapies in those with HIV/AIDS, HIV/HCV co-infection, mild HCV and healthy subjects.
The purpose of this study is to identify 1 or more doses of daclatasvir, which when used in combination with pegylated interferon alpha and ribavirin, are safe and demonstrate sufficient anti-hepatitis C virus activity.
This is a follow-up study with no treatment and only samples being collected.
