Active clinical trials for "Hepatitis"

Confirm the safety of maraviroc when used as a component of combination antiretroviral therapy in HIV and Hepatitis co-infected patients.

This study will demonstrate the immunogenicity and evaluate the safety/tolerability of the vaccine in Chinese children between 12 and 23 months of age.

The purpose of this study is to find out if taking a combination of telbivudine and adefovir or tenofovir and telbivudine can lower the amount of Hepatitis B virus in patients that have been taking adefovir alone for at least 5 months and have had less than optimal responses. The safety of taking telbivudine and adefovir together or tenofovir and telbivudine together will also be studied.

The HALT-C Trial is a National Institute of Diabetes and Digestive and Kidney Diseases sponsored, randomized clinical trial of long-term use of Peginterferon alfa-2a (pegylated interferon) in patients who failed to respond to prior interferon treatment. All patients who enter the trial will be treated for 6 months with Peginterferon alfa-2a and Ribavirin. Patients who respond to this 6 month treatment will continue to be treated for an additional 6 months. Patients who do not respond to this treatment will be eligible for the long-term maintenance phase of this study where patients will be randomly selected to be treated with Peginterferon alfa-2a or to discontinue treatment for 3.5 years. Patients in both arms of this study will be followed closely with quarterly study visits. The combination of peginterferon plus ribavirin has recently been approved by the FDA for treatment of chronic hepatitis C. Patients who remain HCV-RNA positive after being treated for at least 6 months with peginterferon and ribavirin outside of this study may be eligible to directly enter the randomized portion of the HALT-C Trial. The HALT-C study is designed to determine if continuing interferon long-term over several years will suppress Hepatitis C virus, prevent progression to cirrhosis, prevent liver cancer and reduce the need for liver transplantation.

The purpose of this study is to determine whether the HBAI20 vaccine is safe and more immunogenic than the HBVaxPro-10µg in people who have never been vaccinated with a hepatitis B vaccine and in people who have been vaccinated 6 times with hepatitis B vaccine but do not have a protective anti hepatitis B antibody titer.

The study is aimed at assessing the safety and immunogenicity of HCV prime-boost vaccinations ChAd3-hliNSmut and MVA-hliNSmut, administered intramuscularly in healthy volunteers and DAA treated patients.

The Birth-Cohort Evaluation to Advance Screening and Testing for Hepatitis C (BEST-C) compares the effectiveness of the birth cohort HCV screening strategy with the current risk-based screening approach to detect previous unidentified persons with viral hepatitis C who receive health care in primary systems. The study involved three clinical sites, The University of Alabama, Birmingham; The Henry Ford Health System; and the Mount Sinai Medical Center, each of which developed an independent intervention to experimentally compare the number of positive Hepatitis C Virus (HCV) diagnoses found using the birth-cohort screening approach with that found using traditional risk-based screening, or standard of care strategies. Birth cohort testing is defined as the systematic recommendation of HCV antibody testing to any persons born during the years of 1945 to 1965 who do not have clinically documented evidence of a prior antibody test without regards to the patient's stated risk of exposure to the virus.

The purpose of this study is to examine whether neurocognitive impairments experienced by patients with chronic hepatitis C virus (HCV) infection can be reversed by treating HCV, with a new combination of direct acting antiviral drugs (daclatasvir (DCV), asunaprevir (ASV) and beclabuvir (BCV)). The study will assess the effect of HCV on the central nervous system (CNS) by assessing neurocognitive function and brain injury prior to treatment, and comparing it to the end of treatment, and 4, 12 and 24 weeks after treatment.

The purpose of this study is to determine if 8 weeks of Daclatasvir plus Sofosbuvir with or without Ribavirin is safe and effective in the treatment of genotype 3 hepatitis C infected patients without advanced fibrosis or liver cirrhosis who have never been treated previously.

Hepatitis B virus infection is a common occurrence among patients with HIV. Effective vaccines are available, but there's some uncertainty regarding specific dosages, specially among those who have not responded to an initial vaccination. The purpose of this study is to determine the effectiveness of a simplified immunization schedule compared to a high-dose one.
