Filter by: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).
This is a phase 2 study in which subjects with chronic hepatitis B virus (HBV) infection will receive VIR-2218 alone or in combination with pegylated interferon alfa-2a and will be assessed for safety, tolerability, pharmacokinetics, and antiviral activity.
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])
This Phase 2a study will assess the safety, antiviral activity, and pharmacokinetics (PK) of ABI-H2158 administered once daily for up to 72 weeks in combination with entecavir (ETV) in participants with chronic hepatitis B virus (HBV) infection.
This study evaluates the addition of Tenofovir and Entecavir in the treatment of Hepatitis B-related hepatocellular carcinoma after curative resection in adults. Half of participants will receive Tenofovir disoproxil fumarate, while the other half will receive Entecavir.
To Evaluate the Tolerability and Pharmacokinetics of GST-HG141 Tablets in Single-center, Randomized, Double-blind, Placebo-controlled Multiple-dose, Single-dose, Multiple-dose Phase Ia Clinical Trials in Healthy Subjects .
Protection against Hepatitis B infection is a regulatory and safety cornerstone to infection prevention and control programs involving the healthcare workforce in the United States. Until 2018 when a new adjuvanted vaccine was released, immunization for this population has involved a three-dose series followed by an additional three-dose series for those demonstrating lack of seroprotection. If that lack continued following the second three-dose series, and verification of a negative Hepatitis B antigen status, that person has historically been deemed a non-responder to Hepatitis B vaccine and at potential risk for infection. This non-response status may be used to determine job responsibilities representing excessive risk for the healthcare worker resulting in potential career and practice limitations and decisions. With the release of the new adjuvanted vaccine, there is potential to determine the role that new vaccine may play in promoting an immune response among this non-responding subset of at-risk healthcare workers. The aims of this study include: 1) determining the effect of this adjuvanted vaccine in producing seropositivity in a population of healthcare personnel previously deemed as non-responders following administration of two rounds of the traditional 3-dose series of Hepatitis B vaccine and confirmation of negative Hepatitis B antigen; and 2) determining the personal and professional impact of the lack of immunity to Hepatitis B among healthcare personnel.
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).
