The goals of this clinical study are to compare the effectiveness, safety and tolerability of study drug, tenofovir alafenamide (TAF), versus placebo in teens and children with CHB and to learn more about the dosing levels in children.
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.
HBsAg Loss/Seroconversion is uncommon in Low replicative chronic HBV infection patients. The purpose of this study is to investigate the ability of peginterferon alpha to achieve HBsAg loss/seroconversion therapy in Low replicative chronic HBV infection patients with Low Level HBsAg.
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).
Direct acting antivirals offer a new opportunity to monitor the immune response in Hepatitis C infection. In this study cytokine markers will be measured during therapy up to time point SVR 12 an correlated to clinical Parameters and regular laboratory findings.
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
Chronic hepatitis B (CHB) is a serious liver disease worldwide，HBV MTCT is the important reason to keep high prevalence of chronic HBV infection in China. Intrapartum infection is the main period of neonatal HBV infection. Injecting HBIG and hepatitis b vaccine immediately after birth is the most important method of blocking mother-to-child transmission of HBV. However, regular doses of HBIG combined with hepatitis b vaccine blocking measures still have a failure rate as high as 5% ~ 15%.There are numerous studies to explore pregnancy women with HBV positive, especially high viral load of those women during pregnancy being treated with nucleoside analogs to increase the blocking rate of HBV MTCT, but there is still a failure rate of 2.2% to 18%. In this study, we will explore the efficiency of personalized blocking method of HBV maternal-neonatal transmission in high-risk newborns,according to the venous blood HBsAg state of neonatus at birth.
