Filter by:The purpose of this study is to compare how safe, tolerable, and effective a novel drug, raltegravir, is to a commonly used combination, atazanavir/ritonavir, as initial treatment in HIV/Hepatitis C co-infected injecting drug users on a methadone program.
Hepatitis C is a small RNA virus spread by blood to blood contamination. There are to date 6 known genotypes and within each there are several subtypes. Although all genotypes are distributed worldwide some are more common in certain countries and/or among certain populations.
To study retreatment in patients who failed prior treatment with interferon alpha (pegylated or non-pegylated) with or without ribavirin in a real-life setting in an observational/noninterventional study.
The purpose of this study is to determine if concentration-controlled ribavirin dosing can achieve a targeted level of plasma exposures and if it appears safe and effective compared with standard weight-based ribavirin dosing. Forty, previously treatment-naive participants with genotype 1 disease will be randomized to receive concentration-guided or standard weight-based ribavirin. Peginterferon alfa 2a,ribavirin, and telaprevir will be provided through the study.
The purpose of this study is to evaluate the effect of 48 vs 24 weeks of treatment with Peginterferon alfa-2b plus weight-based ribavirin on Sustained Virologic Response (SVR) and relapse rates in patients infected with genotype 3 chronic hepatitis C (CHC) who do not achieve a Rapid Virologic Response (RVR) but attain a complete Early Virologic Response (cEVR).
HCV002TV is a Phase I study to ascertain the safety and immunogenicity of a novel vaccine against Hepatitis C virus (HCV) in chronically infected patients. The vaccine is based on the sequential delivery, by intramuscular route, of two different adenoviral vectors, of chimpanzee and human origin respectively, bearing the same genetic information for HCV antigens (NS region). The two recombinant vaccine vectors, called AdCh3NSmut and Ad6NSmut, are weakened and unable to multiply within the body; they are designed to induce an immune response against HCV proteins. AdCh3NSmut and Ad6NSmut are being used in the ongoing HCV001 study in healthy volunteers with very good safety and immunogenicity results. HCV002TV is a dose-escalation study; the AdCh3NSmut is administered as priming vaccination and Ad6NSmut as boosting vaccination. The trial includes: - Arm A, in which vaccinated patients are into Interferon-ribavirin therapy (the gold standard therapy for hepatitis C); - Arm B, in which vaccinated patients are not into therapy.
Hepatitis C virus when it leaves the cells in the liver is bound to a type of fat. An component of grapefruit could block this fat and thus lower the amount of virus in the blood stream. We propose that treatment with this ingredient, called naringenin, could be used to block this fat and HCV in persons infected with hepatitis C.
The purpose of this study is to investigate the effect of steady-state concentrations of TMC435 150mg q.d. (once a day) on the steady-state pharmacokinetics of escitalopram 10 mg q.d., 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. TMC435 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.
This randomized, cross-over, open label study will compare the tolerability and handling of application of peginterferon alfa-2a [Pegasys] by autoinjector versus pre-filled syringe in patients with chronic hepatitis C, either on treatment with peginterferon alfa-2a for at least 12 weeks or treatment-naïve for peginterferon alfa-2a. Patients will be randomized to self-injection of 180mcg peginterferon alfa-2a once a week using either an autoinjector or a prefilled syringe for 3 weeks, then switch to use the other method of injection for another 3 weeks. Anticipated time on study treatment is 6 weeks. Target sample size is <100 patients.
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of blinded, single ascending oral doses of ABT 072 under non-fasting conditions in healthy adult Japanese male subjects.
