Filter by:This is a randomized, blinded, placebo-controlled, dose-ranging Phase 1b study of the safety, PK, and antiviral activity of ABI-4334 in treatment-naïve or off-treatment chronic Hepatitis B virus (cHBV) subjects that are Hepatitis B e antigen (HBeAg) positive or negative. The study will enroll up to 5 sequential cohorts of 10 subjects each, for a total of up to 50 subjects, randomized 8:2 to receive ABI-4334 or placebo.
A prospective cross-sectional study in which surgically non-invasive sample-taking is done only for the purpose of the study. Capillary (fingerstick) whole blood and EDTA venipuncture whole blood are collected by a healthcare professional. The collected samples of capillary and EDTA whole blood are tested on iStatis and EDTA whole blood sample will be processed to obtain serum and plasma samples to be tested on the iStatis. An aliquot of the collected serum sample will be shipped to the central laboratory for confirmatory testing. The results from iStatis HBsAg Test results will not be used for patient management decisions.
This is a prospective, open-labled, randomized controlled study to assess efficacy and safety of treatment with Sintilimab (PDL-1 antibody) combined Peg-IFNα-2b in CHB patients on stable NAs treatment.
The goal of this observational study is to evalue the cumulative proportion of patients with OBI who do not develop HBsAg seroreversion and/or an increase of serum HBV DNA by at least 1 log above the lower limit of detection of the assay in a patient who had previously undetectable HBsAg and HBV DNA in serum during the study.
This study is a research aiming to identify knowledge , attitude and practice of population in a village in a remote governorate towards viral hepatitis B and C . It involves home visit interviews with population in this village with the use of questionnaire involving questions asked by the researcher that would be orally answered by the participants to be recorded in papers by the researcher.
Solid Organ Transplantation (SOT) is made possible by the use of a lifelong immunosuppressive treatment. This treatment limits the response of the immune system, enabling long-term survival of the transplanted organ, but also leading to weaker anti-infectious responses. In this study, we will compare the response to a booster Hepatitis B vaccination (HBV) in SOT patients, either after kidney or liver transplantation. We will also compare the immune response depending on the immunosuppressive treatment. In order to provide a detailed picture of the immune response, we will investigate the usual serological response (anti-HBs antibodies), but also the cellular memory (both T and B) using ELISpot assays and flow-cytometry, over a 6 months period following booster vaccination.
This is a phase 2a, open-label, multicenter study investigating the safety, tolerability, and antiviral activity of durvalumab administered at targeted times during a 48-week treatment period of imdusiran in virologically-suppressed CHB subjects
Capillary blood sample results are compared to venous blood results
his clinical trial was conducted to determine the non-inferiority and safety of prophylactic antiviral treatment of Tenofovir alafenamide (TAF) compared to Tenofovir disoproxil fumarate (TDF) in patients with malignant hematological diseases requiring prophylactic hepatitis B antiviral treatment. Confirm. In the case of TAF, domestic evidence when used as a first-line treatment is insufficient, so in this clinical trial, the virus suppression effect compared to TDF during the first administration of TAF to patients with malignant hematological diseases requiring prophylactic hepatitis B antiviral treatment was investigated. We aim to secure non-inferiority and additionally confirm the safety of TAF's known advantages of reducing renal function damage and protecting bone function.
The goal of this is to verify the clinical efficacy of compound probiotics in reducing HBV infection levels and regulating intestinal flora in patients with chronic hepatitis B. The main question it aims to answer is: • Conventional antiviral therapy combined with a 6-month probiotic intervention was used to evaluate the clinical efficacy of reducing HBV infection levels (HBeAg, HBsAg, and HBV DNA levels) and regulating gut microbiota.
