Filter by:This was a single center, open-label, single-arm study in which approximately 28 Hepatitis A virus (HAV)-seronegative healthy subjects were enrolled. There was a screening period of up to 28 days during which subjects were screened for enrollment in the study. Healthy subjects received a single intramuscular (IM) dose of GamaSTAN (0.2 mL/kg), followed by a pharmacokinetic (PK) sampling period of 150 days (approximately 5 half-lives). The protective levels of anti-HAV antibodies were assessed up to 60 days after the administration of GamaSTAN. A PK curve was obtained during the PK sampling period.
Hepatitis B virus (HBV) infection remains difficult to eradicate with about 240 million people living with HBV chronic infection. HBsAg clearance, correlated with a good clinical prognosis, is difficult to achieve even with antiviral treatments (3-14 %). HBV envelope proteins are essential for entry into hepatocyte and are targeted by the immune system. Molecular characteristics of HBV envelope proteins may favour better viral fitness at the entry step into hepatocytes and/or HBV escape from host immunity. Here we investigated whether variability of HBV envelope proteins can contribute to the differential responses to anti-HBV treatment in patients with HBsAg clearance or persistence.
This study evaluates the addition of glycyrrhizin to entecavir in the treatment of patients with chronic hepatitis B in China. Half of participants will receive magnesium isoglycyrrhizinate followed by oral diammonium glycyrrhizinate and entecavir in combination, while the other half will receive a placebo and entecavir.
Randomized, open-label study in treatment naïve and treatment experienced, adolescence to determine the efficacy of Sofosbuvir 400mg/ledipasvir 90mg in treatment naïve and treatment-experienced adolescence. Hepatitis C virus (HCV) infection as measured by the proportion of subjects with sustained viral response 12 weeks after discontinuation of therapy (SVR12)
Most new hepatitis B virus (HBV) infections are acquired perinatally. In this study, pregnant women with HBsAg and HBeAg will receive tenofovir disoproxil fumarate during the last trimester of pregnancy and for two months following delivery. Their infants will receive hepatitis B (HB) immunization, starting with a first dose soon after birth. We hypothesize that the risk of mother-to-child transmission of HBV will be lower than 2%. The results of the study will help define policy to manage HBV infected pregnant women to prevent perinatal transmission.
This multi-center, post-marketing, observational study evaluates the real world safety and effectiveness of glecaprevir plus pibrentasvir use in participants infected with the hepatitis C virus genotype 1 - 6.
The aim of the prospective study is to determine whether combination/ sequential therapy with Entecavir, Peginterferon alfa-2b and immunomodulators Granulocyte Macrophage Colony Stimulating Factor (GMCSF)+vaccine could induce HBsAg loss in chronic hepatitis B patients with maintained Hepatitis B Virus (HBV) DNA suppression on long-term nucleoside or nucleotide analogue (NA).
This trial will evaluate the safety and immunogenicity of: i) measles vaccine (CAM-70) after primary dose at 6 months (MV1) and booster vaccination at 12 months (MV2); ii) a single dose of varicella vaccination at 18 months; and iii) a single dose of hepatitis-A vaccination at 18 months in HIV-exposed and HIV-unexposed South African children.
The aim of the study is to assess the health-related quality of life (HRQOL) and preference-based health utilities of chronic hepatitis B (CHB) carriers in different stages of illness. It will also estimate the cost-effectiveness of anti-viral treatments resulting from the prevention of the progression of disease from uncomplicated CHB carriers to cirrhosis and hepatocellular carcinoma (HCC). The following hypotheses will be tested: 1. Patients with chronic hepatitis B virus (HBV) have poorer health-related quality of life (HRQOL) than the general population; 2. Patients with more severe stages of chronic HB infections have lower health related quality of life and health utility values; 3. Anti-viral treatment can improve the HRQOL and health utility for patients with CHB infections; 4. The cost-effectiveness of different treatments for chronic HBV infections can be directly compared in terms of cost/QALY gained.
The goal of this study is to assess patients' attitudes and knowledge of Hepatitis C, analyze the variables that may influence patients' knowledge, and educate patients on Hepatitis C.
