Active clinical trials for "Hepatitis A"

Insulin resistance is common in people coinfected with HIV and Hepatitis C virus (HCV) and is associated with poor responses to treatment for HCV. Pioglitazone is an FDA-approved medication for the treatment of type 2 diabetes. It works by increasing the body's sensitivity to insulin. The purpose of this study is to determine whether treatment with pioglitazone prior to HCV treatment with peginterferon and ribavirin is safe and effective in improving the treatment outcome in insulin-resistant, HIV/HCV-coinfected people for whom previous treatment with peginterferon and ribavirin was unsuccessful.

This study aims to evaluate the efficacy and safety of peginterferon alfa-2b plus weight-based ribavirin as initial treatment in chronic hepatitis C virus (HCV) genotype 1 patients. All patients will receive peginterferon alfa-2b plus oral ribavirin for 12 weeks. At the end of this period, quantitative PCR will be used to determine the Early Viral Response (EVR) at this point of treatment. Total treatment duration will be 48 weeks for Early Responders, 72 weeks for Slow Responders, and 12 weeks for Nonresponders.

The purpose of this study is to evaluate the antiviral activity and safety of tenofovir disoproxil fumarate (TDF) in Asian-American adults (self-reported Asian descent, living in the United States) with chronic hepatitis B infection. All participants will receive active treatment with TDF for 48 weeks.

To provide open-label entecavir to subjects who have completed previous blinded entecavir trials in Japan and are assessed by the investigator as likely to benefit from additional anti-hepatitis B therapy

The objectives are to demonstrate that entecavir has antiviral activity undetectable HBV DNA measured, the Roche AmplicorTM PCR at Week 48, and to assess the safety and the pharmacokinetic of entecavir in Japanese patients with hepatitis B who have an incomplete response to current lamivudine therapy

The objective of this study is to determine the effectiveness of peginterferon alfa-2b 1.5 mcg/kg/week administered for 52 weeks (wk) in previously untreated participants coinfected with hepatitis virus B and D. After 52-week treatment and 52-week follow-up, the virologic, biochemical, and histological response will be evaluated.

The purpose of this study is to compare the safety, tolerability and effectiveness of 12 weeks of treatment with telbivudine 600 mg daily plus tenofovir DF 300 mg once daily (QD) taken together versus tenofovir DF 300 mg once daily (QD) or versus telbivudine 600 mg monotherapy daily (QD). This is an open-labeled, active controlled, viral kinetics study which means the subjects and study doctor will know what study drug subjects have been assigned. This study is open to male and female subjects, <40 years of age, who have been infected with HBV for at least 6 months and have not received oral treatment for HBV.

This study will evaluate the efficacy and safety of MP-424 with Peginterferon Alfa-2b (PEG-IFN) and Ribavirin (RBV) in patients with (Genotype 1) hepatitis C, who relapsed after previous treatment.

Depression is a common side effect of interferon in the treatment of chronic hepatitis C. The aim of this study is to assess the efficacy and safety of paroxetine, an antidepressant agent, in the prevention of depression induced by PEG-interferon given for the treatment of chronic hepatitis C.

Hepatitis C virus (HCV) infects approximately 170 million people worldwide. The current standard- of- care therapy of chronic HCV infection is a regimen of subcutaneously administered (pegylated)-interferon-α and ribavirin for 24 weeks (for genotypes 2 and 3) to 48 weeks (for genotype 1). The sustained viral response rates (SVR) in patients infected with genotypes 2 and 3 are ~80% but remain <50% in patients infected with genotype 1. The treatment is quite toxic with approximately 30% of patients experiencing adverse events (i.e. depression, fever, anemia, fatigue) requiring dose reduction or discontinuation of therapy. This regimen is contraindicated in women who are pregnant and in patients with decompensated liver disease. The absence of acceptable therapies for many patients with HCV infections makes new therapies desirable for this disease.
