Active clinical trials for "Hepatitis A"

The objective of the study is to evaluate the safety and efficacy of PEG-Intron versus no treatment for the prevention of fibrosis progression in adult participants with moderate to severe liver fibrosis secondary to chronic hepatitis C, who failed PEG-Intron plus Rebetol treatment in protocol P02370 (NCT00039871).

The objective of the study is to evaluate the safety and efficacy of PEG-Intron vs. no treatment for the prevention of disease progression in adult subjects with compensated cirrhosis secondary to chronic hepatitis C, who failed to respond to therapy with an a interferon plus ribavirin.

This study is designed to compare the safety, tolerability and antiviral effects of omega interferon administered alone to omega interferon administered with ribavirin in the treatment of subjects with chronic Hepatitis C virus (HCV) infection.

To evaluate if weekly psychological follow-up make opioid dependent patients in MMT able to accomplish 14 weeks treatment with Peginterferon alfa-2a (PEG-INF) and ribavirin to the same extent than non-opioid dependents. To determine the efficacy of this anti-HCV treatment

A significant proportion of HIV infected people in the U.S. are also infected with hepatitis C virus (HCV). The purpose of this study is to determine the effects of anti-HIV therapy on treatment of HCV with pegylated interferon alfa-2a and ribavirin (PEG/RBV).

This is a Phase 2, multi-center, randomized, open-label study to evaluate the safety, tolerability, and efficacy of Albuferon in subjects with hepatitis C (HEP C) who failed to respond to previous interferon alfa therapy.

The primary objectives of this study are to compare the efficacy, safety, and tolerability of tenofovir disoproxil fumarate (TDF) versus adefovir dipivoxil (ADV) for the treatment of HBeAg-positive chronic hepatitis B. Participants will receive TDF or ADV for 48 weeks (double-blind). After 48 weeks, eligible participants switched to open-label TDF for up to 480 weeks.

The purpose of this study is to determine the safety and tolerability of bavituximab when administered via a vein as a single infusion and to examine how bavituximab behaves in the body and how it affects the amount of hepatitis C virus in individuals with chronic infection.

The purpose of the study is to evaluate the efficacy and safety of Albuferon in combination with ribavirin in interferon (IFN) alfa treatment-naïve subjects with chronic hepatitis C genotype 1. The study will randomize subjects to 1 of 4 treatment groups including 3 different Albuferon groups or to the active control group, peginterferon alfa-2a (PEGASYS, PEG-IFNalfa-2a). All subjects will also receive oral daily ribavirin.

This study will evaluate the safety and effectiveness of lamivudine plus adefovir versus adefovir alone to treat chronic hepatitis B infection. The Food and Drug Administration has approved lamivudine for the treatment of hepatitis B. However, the drug is not effective in all patients, and many of those in whom it initially works develop resistance after 1 to 3 years. Adefovir is an experimental drug that inhibits replication of the hepatitis B virus (HBV). Adefovir used alone may be adequate to provide sustained suppression of the virus and improvement in liver disease. However combining two anti-viral agents may be superior to using one alone, similar to the strategy employed for the treatment of AIDS. This study will test whether the combination of lamivudine and adefovir is better than adefovir alone for the treatment of chronic hepatitis B. Patients 18 years of age and older, who have been infected with HBV for at least 6 months, may be eligible for this study. Candidates may not have received lamivudine treatment in the past 6 months or prior treatment with adefovir and must not be taking other anti-viral treatments for their hepatitis. They will have a blood test to confirm HBV infection. Participants will be admitted to the NIH Clinical Center for 2 to 3 days for a medical evaluation. One to 2 weeks after the evaluation, patients will be randomized to begin taking lamivudine and adefovir, or adefovir alone. Therapy will continue for at least 12 months. Follow-up clinic visits will be scheduled weekly for the first month, then every 4 to 8 weeks for the rest of the treatment period. Patients will be evaluated at the end of 1 year. Patients who have not improved with treatment will stop taking the treatment and will be evaluated in the clinic once every 4 weeks for another 6 months. Patients who show an improvement in their liver injury may continue taking lamivudine and adefovir or adefovir alone for 4 more years, as long as they continue to improve with the medication. Progress will be evaluated. If the test results show no continued improvement or are negative for hepatitis B antigens, therapy will be stopped. Patients who continue treatment for 5 years will be readmitted at year 4 for another medical evaluation to assess the effects of treatment at that time. After the 5 years all patients will stop therapy at and be followed with regular clinic visits for at least 6 months.
