Active clinical trials for "Hepatitis C, Chronic"

The purpose of the study is to investigate if the duration of treatment of hepatitis C with pegylated interferon and ribavirin can be individualized on the basis of how fast the hepatitis C virus concentration in the blood decreases, and if this is more cost-efficient than standard treatment.

The investigators will evaluate the efficacy of high dose vitamin C in chronic hepatitis patients whose serum liver enzymes are elevated more than upper limit.

This is a research study to evaluate the safety, tolerability and anti-viral activity of GS-9669 in patients with Hepatitis C infection.

The purpose of this study is to estimate the rate of sustained virologic response (SVR) SVR12, where SVR12 is defined as HCV RNA < LOQ (detectable or undetectable) 12 weeks post-treatment in Genotype 1 & Genotype 4 treatment naive patients, and Genotype (GT1) infected patients who are prior null responders to pegIFN/ribavirin

The purpose of this study was to evaluate the efficacy, safety and pharmacokinetics of ABT-450/r when given together with ABT-267 and with and without RBV in treatment-naïve participants with genotype 1, 2 or 3 chronic HCV infection.

This multi-center, open-label study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) and Copegus (ribavirin) in relation to IL28-b gene expression in treatment-naïve patients with chronic hepatitis C genotype 1. Patients will receive Pegasys (180 mcg sc weekly) and Copegus ( 1'000 or 1'200 mg orally daily) for 48 weeks. Anticipated time of study treatment is 48 weeks, follow-up is 24 weeks.

The purpose of this study is to evaluate the safety, tolerability, and efficacy of vaniprevir given in combination with pegylated interferon alfa-2b (PegIntron®/peg-IFN) and ribavirin (RBV) in chronic hepatitis C (CHC) Genotype I (GT 1) participants who relapsed after previous therapy with interferon-based therapy. The primary efficacy hypothesis is that the percentage of participants achieving sustained virologic response 24 weeks after completion of all study therapy (SVR24) in at least one of the vaniprevir 300 mg twice daily treatment regimens is greater than 20% (historical data of standard of care treatment).

The purpose of this study is to evaluate the impact of a physician directed education program on treatment compliance of hepatitis C patients administered triple drug therapy of pegylated interferon, ribavirin and boceprevir.

This is an open-label, randomized, comparative, multicenter, 48-week study designed to evaluate the efficacy and safety of combination treatment with pegylated interferon and ribavirin in adult subjects with a diagnosis of compensated chronic hepatitis C (hepatitis C virus (HCV)-ribonucleic acid (RNA) positive) (Genotype 1). All subjects will complete 24 weeks of treatment, termed the Pilot Treatment Program, after which all eligible subjects will be randomly assigned to one of two study groups. One group will be followed for an additional 48 weeks without study medication, while the other will be continuously treated for an additional 24 weeks and then followed for another 24 weeks without study medication. Sustained virologic response, defined as undetectable HCV-RNA in serum at the end of the follow-up period, will be measured along with other outcomes.

This study is a 24-week multicenter, randomized, double-blind control trial with ursodeoxycholic acid (UDCA) in patients with chronic hepatitis C in Japan. The primary objectives of this study are to verify the superiority of efficacy of UDCA 600 or 900mg/day to that of 150mg/day and the safety of UDCA treatment.
