Filter by:Primary Objective: To describe the persistence of Hep B antibodies (Ab) at 12 to 18 months of age following a three-dose infant primary series vaccination of either Hexaxim®/Hexyon®/Hexacima® or Infanrix® hexa at 2, 4 and 6 months of age following Hep B vaccination at birth.
CF patients are at risk for hepatic disease. Vaccination is recommended to all CF patients according to European consensus. The aim of the study is to vaccinate as many patients as possible and to follow up whether immunization has been complete.
As HBsAg clearance is uncommon in chronic hepatitis B (CHB) patients on nucleoside analogues (NAs) therapy. The purpose of this study is to optimize HBsAg clearance in CHB Patients with sequential treatment of pegylated interferon alpha-2b and NAs.
This is a study of the efficacy and safety of peginterferon alfa-2a (Pegasys) in naive, interferon- or lamivudine-pretreated participants with HBeAg-positive chronic HBV. Following 48 weeks treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
This is a multiple-center, randomized, double-blind, placebo-controlled, single-ascending dose and multiple-ascending dose, adaptive parallel study to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of RO7020322 following oral administration in healthy participants and chronic hepatitis B patients.
Patients with HBeAG positive, chronic HBV infection will receive either ARC-520 or placebo in combination with entecavir or tenofovir, and be evaluated for safety and efficacy.
Patients with chronic HBV infection will receive either ARC-520 or placebo in combination with entecavir or tenofovir, and be evaluated for safety and efficacy.
Recent evidence suggests that patients with inactive chronic hepatitis B (CHB) may develop the same types of liver complications that patients in the active state of hepatitis B virus (HBV) infection experience. Treatment guidelines for patients in the active state of HBV infection indicate that HBsAg clearance is associated with definitive remission of the activity of chronic HBV & improved long-term outcome. Clinical data showed that HBsAg clearance is achievable, in a small population of patients on continuous treatment with potent oral antivirals (OAVs), such as tenofovir disoproxil fumarate (TDF). It is possible the same OAVs can have the same effect in patients with inactive CHB, but in a shorter treatment duration. The purpose of this study is to find out if TDF is effective in controlling HBV DNA & promoting seroconversion from HBsAg-positive to HBsAb-positive in patients with inactive CHB.
This study will evaluate the efficacy and safety of peginterferon alfa-2a or ADV, in participants with lamivudine-resistant HBeAg-positive chronic hepatitis B. Participants will be randomized to receive either peginterferon alfa-2a for 48 weeks in combination with oral lamivudine for the first 12 weeks, or ADV for 72 weeks in combination with oral lamivudine for the first 12 weeks. The anticipated time on study treatment is 72 weeks, and the target sample size is 255 individuals.
The "Thousand Asian American Study" or "TAAS" aims to test 2,000 foreign-born and children of foreign born Asian Americans residing in Sacramento county residents for HBV and (2) counsel at least 90% of those whose screening results are positive for HBV.
