Filter by:Different Doses of rosuvastatin and atorvastatin will be used to see if HCV viral load changes and liver tests change.
The objective of the study is to select an optimal dose of taribavirin by comparing the efficacy and safety of 3 taribavirin dose levels, 20, 25, and 30 mg/kg/day, versus ribavirin 800 to 1400 mg/day based on body weight, both administered in combination with peginterferon alfa-2b to therapy-naive patients with chronic Hepatitis C Virus (HCV) genotype 1 infection.
Pevion Biotech has designed a therapeutic vaccine to treat patients who suffer from chronic hepatitis C virus infection. The vaccine is based on a combination of the PeviPRO and PeviTER platforms using synthetic peptide antigens from the hepatitis C virus. Generally, a cellular immune response by cytotoxic T-lymphocytes (CTL) seems to be crucial in overcoming a hepatitis C virus infection. In-depth research in recent years has shown that the cellular immune response is even more effective when supported by helper T-cells. Pevion Biotech's HCV vaccine candidate utilizes this effect inducing specific CTL responses (PeviTER) together with a supportive helper T cell response (PeviPRO). This virosome-based technological combination in a single product represents a new generation of modular therapeutic vaccines.
Assess the safety, tolerability and pharmacokinetics of multiple oral doses of PF-00868554 in HCV positive patient volunteers
Hepatitis C virus infection (HCV) is a major health concern in Canada and worldwide. Chronic HCV can cause progressive liver damage leading to inflammation, scarring and, in some cases, cirrhosis or liver cancer. It has been shown that fat accumulation in the liver can accelerate the disease progression and is therefore a risk factor in HCV patients. However, the exact mechanism(s) by which fat accumulation in the liver is involved in disease progression are not clear yet. It is possible that the presence of fat provides a liver susceptible to a second injurious process which leads to scarring. Candidates for this second "hit" may include insulin resistance, leading to accumulation of fat within the liver cells and secondly oxidation of these lipids. In turn, lipid peroxidation can lead to production of reactive oxygen species (unstable molecules that can damage cells) and cytokines (signal molecules that promote inflammation) resulting in more oxidative stress and liver damage. Aim of the study is to find out, whether patients with HCV and fatty liver have increased oxidative stress and inflammation than patients with HCV without fatty liver, and whether this is associated with a different nutritional status.
This 2 arm study will evaluate the efficacy and safety of intermittent treatment with PEGASYS in HBeAg negative patients with chronic hepatitis B who have demonstrated virological and biochemical response after treatment with interferon alfa. After 48 weeks therapy with interferon alfa, and 24 weeks treatment-free follow-up, eligible patients will be randomized into the PEGASYS or the observational group. Those in the PEGASYS group will receive 4 therapeutic cycles of long term intermittent treatment with PEGASYS (135 micrograms sc weekly for 12 weeks, followed by a treatment-free period of 12 weeks) and those in the observational arm will receive no specific antiviral treatment. The anticipated time on study treatment is 1-2 years, and the target sample size is 100 individuals.
This 48-week open-label study of local manufactured adefovir dipivoxil Tablet evaluates the efficacy and safety of adefovir 10mg once daily in Chinese subjects with compensated CHB. Primary endpoint is proportion of subjects achieving HBV DNA undetectable (<=1000 copies/mL by by Roche COBAS AMPLICOR HBV MONITOR Test) at week 48. Approximately 1250 patients will be recruited in 30 study centers in China. The subjects are offered 48 weeks of open label adefovir dipivoxil treatment, with assessments every three months, after with is a 12-week post study treatment follow-up prior to study completion.
This is a dose finding and efficacy trial for fluvastatin versus hepatitis C.
The purpose of this trial is to determine if there is an improvement in the immune response of older adults over 50 years of age using a modified process hepatitis B vaccine and a currently licensed hepatitis B vaccine (RECOMBIVAX HB™).
To describe the immunogenicity and safety of modified process hepatitis B vaccine administered to renal predialysis and dialysis patients
