Active clinical trials for "Hepatitis A"

Omega DUROS® is an implantable drug delivery system designed to deliver omega interferon subcutaneously at a constant rate for 90 days. This study is being performed to evaluate the safety and antiviral effects of omega interferon delivered by the Omega DUROS® device in combination with ribavirin in subjects with chronic Hepatitis C genotype 1.

Pegylation of interferon prolongs the medication half-life which has resulted in Pegylated Interferon (PEG-IFN) as the new modality for treatment of chronic hepatitis C. We current this clinical trial to assess the efficacy and safety of domestic PEG-IFN alpha-2a (Pegaferon®) in the patients with chronic hepatitis C.

The primary objective is to determine the safety of sub-cutaneous (SC) injections of TG4040 in non-cirrhotic, treatment-naïve patients chronically infected with HCV (genotype 1). Patients will be sequentially treated at an escalting dose of TG4040. All patients will be followed up to at least 6 months after his/her first injection. In addition, all patients treated at the highest dose will receive a TG4040 boost injection 6 months after the first injection, and will be followed up during an additional 6-month period.

This study is to evaluate the antiviral efficacy of add-on adefovir to telbivudine in non-responders to telbivudine monotherapy after 24 and 36 initial weeks. Antiviral efficacy is assessed by hepatitis B virus (HBV) DNA non-detectability (PCR <300 copies/ml) by week 104 with CHB.

The purpose of this study is to evaluate the activity and safety of telaprevir on Hepatitis C Virus (HCV) Genotype 4, alone or in combination with standard therapy, that is, pegylated-interferon-alfa-2a and ribavirin in treatment-naive (never been treated before with antiretroviral therapy) participants.

Assess the safety, tolerability and pharmacokinetics of multiple oral doses of PF-00868554 in HCV positive patient volunteers

This study will evaluate the efficacy and safety of 4 regimens of PEGASYS plus Copegus, in patients with chronic hepatitis C (CHC) genotype 1 who have failed to respond to previous treatment with standard doses of PEGASYS plus ribavirin. Patients will be randomized to one of 4 groups, to receive a)PEGASYS 360 micrograms/week plus Copegus 1000-1200mg/day, b)PEGASYS 180 micrograms twice weekly plus Copegus 1000-1200mg/day, c)PEGASYS 360micrograms/week plus Copegus 1200-1600mg/day, or d)PEGASYS 180 micrograms twice weekly plus Copegus 1200-1600mg/day. Following 48 weeks treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

We hypothesize that atorvastatin will decrease HCV viral load in patients taking the medication. Cholesterol is needed for HCV virion production. Cell culture studies have shown that atorvastatin (an HMG-CoA reductase inhibitor) decreases HCV viral replication. As atorvastatin has been proven to decrease heart attack and stroke in patients with high cholesterol, this medication is indicated for the treatment of elevated cholesterol in at risk individuals. Therefore we propose to study the effect atorvastatin has on the viral load of patients initiated on atorvastatin therapy for their elevated cholesterol.

This exploratory study is designed to determine the early viral kinetic profile during treatment with telbivudine or entecavir at multiple time points over 12 weeks.

The purpose of this study is to evaluate the effectiveness of entecavir plus adefovir combination therapy versus entecavir monotherapy or therapy with adefovir plus lamivudine
