Filter by:The purpose of this study is to evaluate effectiveness, safety and pharmacokinetics (Explores what the body does to the medication) of TMC435350 in combination with Peginterferon Alfa-2a and Ribavirin in genotype 1 hepatitis C virus infected Japanese participants who have never received treatment for their hepatitis C infection.
The purpose of this study is to assess the effect of BMS-790052 on the pharmacokinetics of Ortho Tri-Cyclen® in healthy female subjects.
The objective of the present study is to evaluate the antioxidant status in the blood of HCV patients treated with pegylated interferon (2a 1.5 ug/kg; 2b 180 ug) combined with ribavirin (1000 to 1250 mg) before and after supplementation of vitamins E, C and the mineral zinc (800 mg,500 mg and 40 mg; respectively) during six months.
This is a study designed to identify a dose of NIM811 that has a good safety profile, is well tolerated when co-administered with SOC, and provides a clinically meaningful effect in viral load reduction compared to SOC alone. This information will be used to support doses selected for future studies.
Combination therapy with peginterferon plus ribavirin has become the current standard of care for chronic hepatitis C (CHC) patients, with an overall sustained virologic response (SVR) rate of 54-63%. Based on the ample evidence, a 48-week course of peginterferon plus weight-based ribavirin therapy is widely recommended to treat HCV genotype 1 infection in different parts of the world. Despite the increased SVR rates with the improved medical therapies, about 25-50% and 10-20% of HCV genotype 1 and HCV genotype 2/3 patients may experience relapse after the cessation of therapy with undetectable HCV viremia at the end of treatment. Moreover, combination therapy is costly and may cause various adverse events. Therefore, individualized therapy based on outcome analysis should be adopted to save medical cost as well as to lessen inadequate treatment. Few studies are aimed to evaluate the host responses of micro RNA regulation during interferon-based therapy and its relationships to the overall treatment responses. Micro RNA (miRNA) is a single-stand RNA composed of 21-23 nucleotides, which may regulate the function of messenger RNA (mRNA). The regulating mechanisms involving micro RNA between the hosts and the HCV virus include (1) auto-regulation of HCV mRNA by HCV miRNA; (2) regulation of host mRNA by HCV miRNA; and (3) regulation of HCV mRNA by host miRNA. MiR-122 is the abundant liver-specific miRNA which is crucial for efficient HCV replication in culture Huh7 cells stably expressing HCV replicons. Recently, an in vivo study for hepatic miR-122 of 42 patients with CHC who received IFN-based therapy showed that patients who did not respond to IFN therapy had markedly decreased pretreatment miR-122 levels. Although miR-122 is abundant in the liver, liver biopsy is still considered an invasive procedure, which prevents its widespread use in routine clinical practice. The miRNA can be detected in the sera and is stable after 24 hours of room temperature store or repeated freezing and de-freezing. The serum miR-122 levels can reflect the severity of liver injuries in a rat acetaminophen toxicity model. Because miR-122 is liver specific and the miRNA is stable in the sera, the investigators aimed to evaluate the role of serum and hepatic miR-122 on the viral kinetics and the treatment responses and in HCV patients receiving peginterferon and ribavirin combination therapy.
The purpose of this study is to determine the antiviral effect following three days of dosing with BMS-824393 in chronically genotype subtype 1a and 1b Hepatitis C virus (HCV) infected subjects.
SCV-07 (γ-D-glutamyl-L-tryptophan) is a new immunomodulatory compound that has been developed and patented both for composition and immunomodulatory use and is a synthetic dipeptide. The efficacy of SCV 07 in treating chronic hepatitis C virus (HCV) infection is expected to arise from the drug's ability to stimulate the T-helper 1 (Th1) type immune response and to block signal transducers and activator of transcription 3 (STAT3) mediated signaling. The purpose of this study is to determine if SCV-07 alone and/or SCV-07 in combination with ribavirin is safe and potentially effective for the treatment of genotype 1 compensated chronic hepatitis C in subjects who have relapsed after a response to a previous treatment course of at least 44 weeks with pegylated interferon and ribavirin. All subjects will receive 4 weeks of SCV-07 (Lead-in Phase), followed by 4 weeks of treatment with SCV-07 in combination with ribavirin (Combination Treatment).
This 2 part study will evaluate the efficacy and safety of 12 and 24 weeks treatment with RO5190591 (danoprevir) in combination with Pegasys and Copegus, compared to Pegasys and Copegus alone, in treatment-naive patients with chronic hepatitis C genotype 1 virus infection.In Part 1 of the study, patients will be randomized to receive either 1) RO5190591 300mg po every 8 hours, 2) RO5190591 600mg po every 12 hours, 3) RO5190591 900mg po every 12 hours or 4) placebo, in combination with standard doses of Pegasys and Copegus. If the safety and virological response data from Part 1 of the study are supportive, in Part 2 patients will be randomized to receive either 1) RO5190591 300mg po every 8 hours or 600mg po every 12 hours or 900mg po every 12 hours or 2)placebo, in combination with standard doses of Pegasys and Copegus. The anticipated time on study treatment is 24-48 weeks, and the target sample size is 100-500 individuals.
This study aims to evaluate whether an investigational monoclonal antibody, CT-011, is safe to give and if it helps patients with hepatitis C virus (HCV). Monoclonal antibodies are a type of drug that is typically given by infusion into a vein (intravenously). Results of this trial will help doctors obtain additional information with regard to the safety and efficacy of CT-011 as a potential treatment for HCV.
The purpose of this study is to demonstrate the relative bioavailability of Ribavirin 200 capsules and Rebetol 200 mg capsules in females under fasting conditions.
