Filter by:This study is being done to determine if healthcare workers who have previously failed to respond to hepatitis B vaccine series will respond to a hepatitis B with CpG adjuvant (hepB-CpG) (Heplisav-B)
Chronic hepatitis B virus (HBV) infection is a significant worldwide medical problem. GSK3228836 demonstrated target engagement in CHB participants who were not on treatment and in CHB participants on stable nucleos(t)ide therapy. This study is intended to evaluate if treatment with GSK3228836 can achieve sustained virologic response (SVR), that is hepatitis B virus surface antigen (HBsAg) less than (<) lower limit of quantitation (LLOQ) and HBV deoxyribonucleic acid (DNA) <LLOQ sustained for 24 weeks post-GSK3228836 treatment end. In addition, the study will also evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic properties of GSK3228836 in the 4 dosing regimens. This study will assess the efficacy and safety of treatment with GSK3228836 in two populations of participants with CHB; participants on stable nucleos(t)ide treatment (Cohort 1) and participants who are not currently on nucleos(t)ide therapy (Cohort 2). For each population, participants will be randomized into one of the 4 different parallel arms to receive treatment. The study will consist of a screening, treatment, and post-treatment follow-up phase. Approximately, 440 participants will be enrolled in the study.
The purpose of this study is to evaluate the efficacy of a treatment regimen of JNJ-73763989 + pegylated interferon alpha-2a (PegIFN-alpha-2a) + nucleos(t)ide analog (NA).
Primary Objective: To demonstrate the non-inferiority of the SHAN6™ vaccine to the licensed SHAN5™ given with bOPV and IPV vaccines when coadministered with PCV and ORV Secondary Objective: - To describe the immunogenicity profile of the SHAN6™ vaccine 3-dose primary infant vaccination and that of the control vaccines (SHAN5™ given with bOPV and IPV) - To describe the immune response to co-administered ORV-1 (Rotarix™) in a subset of participants from each group - To describe the immune response to co-administered PCV-13 (Prevnar 13®) in a subset of participants from each group - To describe the persistence of the antibodies against SHAN6™ antigens following a 3-dose primary series of SHAN6™ or SHAN5™ given with bOPV and IPV - To describe the immunogenicity profile of SHAN6™ 28 days after the single booster dose of SHAN6™ - To describe the safety profile of the SHAN6™ vaccine and the control vaccines (SHAN5™ given with bOPV and IPV), when administered concomitantly with routine pediatric vaccines
A Phase II Randomized, Double-blind, Placebo-controlled, Multi-center, Dose-effect Relationship Study of Hepalatide for Injection Combined with Pegylated Interferon in Subjects with Chronic Hepatitis B
This is a Phase 1 study in which healthy volunteers and participants with chronic HBV infection will receive VIR-3434 or placebo and will be assessed for safety, tolerability, pharmacokinetics (PK), and antiviral activity (only in participants with chronic HBV infection).
Primary objectives: - To assess the safety profile of each SP0202 formulation and Prevnar 13 in toddlers and infants (after each and any injection). - To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after the administration of one dose in toddlers (Groups 1-4) - To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after the administration of 3 doses in infants (Groups 5-8) - To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after administration of a 4-dose schedule in infants (Groups 5-8) Secondary objectives: - To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after the administration of one dose in toddlers (Groups 1-4) - To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after the administration of 3 doses in a subset of infants (Groups 5-8) - To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after administration of a 4-dose schedule in a subset of infants (Groups 5-8) - In toddlers: to describe the Ab responses against Pentacel antigens before and 1 month following injection of Pentacel - In infants: to describe the Ab responses against antigens of the routine pediatric vaccines (Pentacel, RotaTeq, ENGERIX-B, M-M-RII, and VARIVAX) when administered concomitantly with either SP0202 or Prevnar 13 (at pre-Dose 1 (as applicable) for RotaTeq, Diphteria, Tetanus and Pertussis antigens; at PD3 for ENGERIX-B, RotaTeq, and Pentacel; at PD4 for M-M-RII and VARIVAX])
To assess the prevalence of blood-borne viral infections in prisons in Belgium, screening will be executed in several prisons in Flanders, Brussels and Wallonia to obtain a geographical representative distribution. Upon informed consent screening will be performed using whole capillary blood (finger prick testing) with three different tests for HCV Ab, HBsAg and HIV. Screening will be performed first. While awaiting the test result (15-20min), the participant can fill out a questionnaire (together with the study nurse), concerning risk factors for HCV, HBV and HIV infection. This questionnaire is filled out directly online, and will be immediately implemented in the encoded database. The database is set-up according to the rules of good clinical practice. (Castor EDC software). The results will be filled out immediately by the prison staff in this database after it is filled out by the participant, minimizing the risk of displacement of test results.
This is a multi centre, two parallel arm, randomized, open-label, Phase 2a experimental study of oral Farnesoid X Receptor (FXR) modulator EYP001a to assess its safety and anti-viral effect when administered to non-treated (treatment naive or off treatment) chronic Hepatitis B (CHB) patients in combination with entecavir (ETV) and pegylated interferon alpha2a (peg-IFN). An experimental treatment period of 16 weeks will be followed by a 24 week maintenance period with ETV standard of care (SoC).
Title Reaching out to the UNdiagnosed people infected with blood-borne viral infections (RUNtoBBV) Objectives 1. To study the efficacy of an outreach methodology to increase the uptake for screening, linkage to care and treatment in (active or former) people who use drugs (PWUD) Trial design Prospective multicenter interventional cohort design Number of subjects 336 inclusions (with prevalence of HCV Ab: 30%) - 168 Antwerp - 168 Limburg Selection criteria Inclusion criteria: - 18 years of age - History of/ or active drug use - Written informed consent obtained Exclusion criteria - Currently enrolled in centralized OST program of Free Clinic or CAD Limburg Endpoints The following endpoints will be compared between the centers in Limburg and Antwerp: (Main outcome in bold) Main objectives: - Prevalence of blood-borne viral infections in Belgian (former or active) PWUD: - HCV infection (number of HCV Ab+ / number of screened PWUD) - HBV infection (number of HBsAg+/number of screened PWUD) - HIV infection (number of HIV Ab+/number of screened PWUD) - Analysis of linkage to care to hepatologist/ infectiologist (number of patients who adhered to their consultation/number of referred patients) Secondary objectives: - Analysis of risk behavior/sociodemographics linked to presence of BBV infections - Analysis of uptake of anti(retro)viral treatment (number of patients started on treatment/number of patients needing treatment) - Analysis of treatment adherence (adherence to treatment consultations/total planned consultations) - Analysis of treatment outcome (total number of cured or virally suppressed patients/total number of treated patients)
