Active clinical trials for "Hepatitis A"

To assess the efficacy and safety profile of co-administration of BMS-790052 and BMS-650032 for 24 weeks treatment.

Injection drug use accounts for transmission of a high proportion of Hepatitis C Virus (HCV) infections. The purpose of this trial is to investigate the effectiveness of pegylated interferon in treating injection drug users (IDUs) with acute HCV.

The presence of insulin resistance (IR) appears to be a key factor in the development of steatosis and disease progression in patience with Hepatitis C virus (HCV) genotype-1 infections similar to levels in Non-alcoholic fatty liver disease (NAFLD). The objective of this study is to determine whether Pioglatizone, when given along with Interferon and Ribavirin, reduces insulin resistance and lowers HCV viral levels and improved response in patients who have HCV genotype-1 infection when compared to a placebo.

Objectives: Primary To compare the sustained virologic response (SVR) of PEGIntron plus ribavirin among patients receiving 48 weeks versus 72 weeks of therapy (defined as undetectable HCV RNA level 24 weeks after discontinuing therapy). Secondary To evaluate the safety and tolerability PEG Intron in combination with ribavirin for treatment of Chronic Hepatitis C (CHC) infection in patients co-infected with Human Immunodeficiency Virus (HIV). To determine the early virologic response of patients receiving PEGIntron plus ribavirin at Treatment Week 24 Study Design: All qualifying patients will enter the treatment phase and be dosed as follows: Peginterferon a-2b 1.5mg/kg by subcutaneous route once weekly plus Ribavirin: 800 mg (400 mg bid) if body weight < 65 kg 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg 1200 mg (600 mg bid) if body weight > 85 kg and < 105 kg 1400 mg (600 mg a.m. and 800 mg p.m.) if body weight > 105 kg At Treatment Week 24, all participants with detectable HCV-RNA will be discontinued from treatment and followed for a Post Treatment period of 24 weeks. Participants with undetectable HCV-RNA values at Treatment Week 24 will be randomized to either: Group A: an additional 24 weeks of previously assigned Peginterferon a-2b + Ribavirin therapy, for a total of 48 weeks of treatment. Group B: an additional 48 weeks of previously assigned Peginterferon a-2b + Ribavirin therapy, for a total of 72 weeks of treatment. Study Population: 300 HIV infected adults with chronic hepatitis C infection who have not been treated previously with interferon therapy. Dosage and Administration: Peginterferon a-2b 1.5mg/kg by subcutaneous route once weekly plus Ribavirin: 800 mg (400 mg bid) if body weight < 65 kg 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg 1200 mg (600 mg bid) if body weight > 85 kg and < 105 kg 1400 mg (600 mg a.m. and 800 mg p.m.) if body weight > 105 kg Efficacy Evaluations: Laboratory analysis, liver biopsies, quality of life assessments, and changes in Peginterferona-2b and Ribavirin dosages will be obtained. Safety Evaluations: Assessment of laboratory evaluations vital signs incidence and severity of adverse experiences dose adjustments premature withdrawal for safety reasons progression of disease as measured by HCV viral load AIDS defining events

The primary objective of this study is to determine the safe and effective dose range of boceprevir (SCH 503034) in combination with PEG-Intron in adult subjects who have chronic hepatitis C without cirrhosis, and who have failed an adequate course of combination therapy with peginterferon-alfa plus ribavirin. A secondary objective is to explore whether ribavirin provides an additional benefit when combined with PEG-Intron plus boceprevir.

The purpose of this study is to see which of two doses of PEG (polyethylene glycol) interferon alfa-2b in combination with Ribavirin for 48 weeks is more effective at elimination of hepatitis C. The primary objective of this study is to compare the efficacy of Induction PEG-Interferon alfa-2b (PEG-Intron) and Ribavirin (Rebetol) to standard PEG-Interferon alfa-2b (PEG-Intron) and Ribavirin (Rebetol) in patients with chronic hepatitis C.

The primary purpose of the study is to evaluate the effectiveness, safety, and tolerability of tenofovir disoproxil fumarate (TDF) in adolescents (aged 12-17 years) with chronic hepatitis B virus (HBV) infection. The optimal treatment for adolescents with chronic HBV infection is currently unknown. Treatment with interferon alfa, lamivudine, and adefovir dipivoxil in pediatric populations has been shown to be less than optimal. Further, the safety and efficacy of entecavir and telbivudine have not been established in patients < 16 years of age. A study evaluating TDF in adolescents (ages 12-17) was needed to assess the safety and efficacy of this agent in the treatment of chronic hepatitis B in this patient population. In addition, the study will help to further elucidate the pharmacokinetic (PK) and resistance profiles of TDF. Through their participation, study participants will help generate critical new information to help guide the most optimal treatment of chronic HBV infection in adolescents. This is a randomized, double-blind study to evaluate the antiviral efficacy, safety, and tolerability of TDF versus placebo in adolescents with chronic HBV infection. TDF treatment-naive participants were randomized in a 1:1 ratio to TDF or placebo. After 72 weeks of blinded treatment, participants were to switch to open-label TDF for an additional 2.5 years of treatment, provided that no safety concerns are identified by the Independent Data Monitoring Committee monitoring the study.

This is an open label, single-arm, multi-centre extension study for Korean patients with chronic hepatitis B and compensated liver disease who have completed one-year adefovir dipivoxil treatment in ADF103814. The objective is to assess clinical efficacy and safety of long term (up to 3 years) adefovir dipivoxil 10mg therapy.

The purpose of this clinical research study is to assess the safety effectiveness of entecavir, as compared to lamivudine, in the treatment of adults with chronic hepatitis B infection who are hepatitis B e antigen positive.

Purpose of this study is to evaluate the safety, tolerability, antiviral activity, and pharmacokinetic behavior of ISIS 14803 administered for up to 12 weeks by intravenous infusions in patients with chronic hepatitis C.
