Active clinical trials for "Hepatitis"

The purpose of this study is to compare the adefovir early add-on to rescue therapy strategy, and also explore the efficacy of Lamivudine and adefovir de-novo combination therapy.

This is a Phase 2b, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating Response Guided Therapy with GS-5885 Alone or in Combination with GS-9451 with Peginterferon Alfa 2a and Ribavirin in Treatment Naïve Subjects with Chronic Genotype 1 Hepatitis C Virus Infection.

Switching to Entecavir will result in superior antiviral efficacy as compared to continuing with Adefovir in patients with a suboptimal response to Adefovir

The purpose of this study is to assess the interactions seen when somebody doses with TMC435350 and Rifampin (commercial form of antibiotic).

The purposes of this study are: To evaluate whether treatment with peginterferon and ribavirin for 24 weeks is sufficient to achieve a sustained virological response (SVR) rate comparable to that observed with the standard treatment duration of 48 weeks, in hepatitis C virus genotype 1 (HCV-1) patients achieving a rapid virologic response (RVR; <50 IU/mL HCV RNA at week 4) at 4 weeks. To investigate the role of on-treatment virological responses among patients with 24 or 48 weeks treatment.

A double-blind randomized, parallel, multicenter with 48 weeks of treatment period. The purpose of this study is to compare the safety and antiviral activity of 48-week Clevudine and Adefovir dipivoxil in HBeAg(-) Chronic Hepatitis B with compensated liver function.

Open-label pharmacokinetic drug interaction study.

This study examines the safety, tolerability, and immunogenicity of a single dose of MDX-1106 in patients with active hepatitis C genotype 1 or mixed hepatitis C genotype infection.

The purpose of this study is to test the safety, tolerability, and efficacy of 4 regimens of Vaniprevir + Peg-IFN and Ribavirin as compared to Placebo (PBO) + Peg-IFN/RBV. The primary hypotheses are that Vaniprevir is well tolerated, and that Vaniprevir 600 mg twice daily (b.i.d.) is superior to the control regimen for the percentage of non-cirrhotic (NC) participants achieving undetectable HCV ribonucleic acid (RNA) 24 weeks after the end of study therapy (SVR24).

Current treatment of chronic liver disease relies upon removing the primary insult to the liver (e.g., alcohol) or treating the underlying viral infection (HBV, HCV, etc.). However, in the case of hepatitis C, a significant number of individuals will not clear the virus with current approved standard antiviral therapy, leaving them no options to manage their hepatic fibrosis, which can progress to cirrhosis and ultimately hepatocellular carcinoma (HCC). Fuzheng Huayu has been used in numerous studies in China and has been found to have a satisfactory prophylaxis effect on the chronic liver injury and formed liver fibrosis in rats and humans. In addition, it enhances the degradation of liver fibrosis and protects hepatocytes from injury and death, manifesting as decreasing of ALT and AST, and enhancement of albumin level. In addition, preliminary studies indicate that the Fuzheng Huayu has a good safety and tolerability profile with promising efficacy. The number of patients failing Interferon based therapy (i.e. not achieving SVR) is increasing. There are no approved standard of care treatment options for this population nor for patients who are intolerant or unwilling to receive Interferon; thus they are at higher risk for the progression of fibrosis. Moreover, there are no approved therapies to treat hepatic fibrosis, but basic research is exploring the pathophysiological mechanisms. Fuzheng Huayu is easy to administer, with a good safety and efficacy profile against fibrosis. Therefore, the investigators propose to further study the safety and efficacy profile of Fuzheng Huayu in a randomized, placebo-controlled, double blind study in Chronic Hepatitis C patients with hepatic fibrosis who have failed prior anti-HCV therapy or are intolerant or refuse Interferon based therapy. The primary objective of this study is to establish the safety and efficacy of Fuzheng Huayu treatment in chronic hepatitis C subjects who have failed prior anti-HCV therapy or cannot receive or refused Interferon based therapy in improving liver fibrosis.
