Filter by:Open-label experimental trial of 12 weeks of Viekira Pak treatment ± ribavirin or Mavyret for adults with chronic kidney disease and hepatitis C.
The main objective of this study is to evaluate the safety and effectiveness of paritaprevir/ritonavir/ombitasvir with ribavirin used for participants infected with chronic hepatitis C virus (HCV) genotype 2 in daily practice in Japan.
The purpose of this study was to evaluate the efficacy and safety of co-administration of glecaprevir (ABT-493)/pibrentasvir (ABT 530) plus sofosbuvir (SOF) plus ribavirin (RBV) in hepatitis C virus (HCV) genotype (GT) 1 - 6-infected participants (including non-cirrhotic, or cirrhotic with compensated cirrhosis participants) who had experienced virologic failure in an AbbVie parent clinical study.
The VISN1 VA Hepatitis C Testing and Linkage to Care Quality Improvement project aims to increase the proportion of Veterans tested for HCV in those born between 1945-1965 and in vulnerable, high-risk groups.
The study is a prospective, single centre, double-blinded randomized controlled trial whose goal is to compare the immune response of a population of immunosuppressed pediatric rheumatology patients on immunosuppressive medications to two different doses of Hepatitis A vaccine. The objectives are (a) to confirm that adolescents, like their adult counterparts, have a reduced immune response to hepatitis A vaccine, and (b) to compare the immunogenicity of two different dosing options of vaccine for this age group after one and two doses. A total of 60 adolescents aged 12 - 15 years with confirmed chronic rheumatologic conditions for which they are being treated with an immunosuppressive therapy will be recruited from the Rheumatology Clinic at Alberta Children's Hospital (ACH). Those found to have no immunity to hepatitis A will be enrolled. Informed, written consent will be obtained from the parent or guardian of subject, with assent obtained from the study subjects. Subjects will be randomly assigned to two doses of either Avaxim Pediatric® or Avaxim ® (adult) vaccine (Sanofi Pasteur Canada), six months apart, with hepatitis A titres done at baseline and one month after each dose. Both formulations are licensed for this age group.
Activation of the immune system against a pathogen can be considered one of the most effective interventions in the field of infectious diseases. Transgene is developing a therapeutic vaccine "TG1050" for the treatment of patients with chronic and treated Hepatitis B. This biotherapy compound is for the development of T cellular immune response in these patients in order to achieve the total elimination of infected cells. Therefore it is necessary to have measures of ways to assess accurately and reliably the presence of such a response in the study subjects.
This two-part, Phase 1 protocol will be the first clinical study of ABI-H0731. Part I will be a Phase 1a dose-ranging assessment of ABI-H0731 in healthy adult volunteers. If the dose-related safety, tolerability and pharmacokinetics (PK) of ABI-H0731 in human volunteers are deemed satisfactory, then the study will advance to Part II, a Phase 1b dose-ranging assessment of ABI-H0731 in non-cirrhotic, CHB patients.
The objectives of this study are to collect and assess data related to safety and effectiveness of Sovaldi treatment regimens, per the approved prescribing information for Sovaldi, in routine clinical practice and report results to Korean Ministry of Food and Drug Safety (MFDS).
The purpose of this study is to assess the long-term protection against HBV infection in adult subjects, aged 18-40 years vaccinated with three or four doses of Engerix-B 20 to 30 years ago
Background Hepatitis B virus (HBV) co-infection in individuals with hepatitis C virus (HCV) can enhance the severity of hepatitis and the risks of liver cirrhosis and hepatocellular carcinoma (HCC). Hepatitis B vaccine is an effective measure to prevent HBV infection. Whether patients with HCV infection have non-protective antibody responses to hepatitis B vaccination more frequently than healthy subjects is still controversial and studies about cytokine response have been seldom reported. Methods Not-in-treatment patients with chronic HCV infection and 1:2 community/gender matched healthy control were obtained from a community-based screening. All participants received three doses of hepatitis B vaccine (20 μg HBsAg/ml/dose) on 0, 1 and 6 months schedule. Anti-HBs was tested 1 month after the third dose of vaccination and was compared between two groups. Spot-forming cells (SFCs) of interferon-γ (IFN-γ), interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-5 (IL-5) and interleukin-6 (IL-6) produced by lymphocyte were tested by enzyme-linked immunospot (ELISPOT) and were compared between two groups.
