Filter by:REP 9AC (REP 2055) is a nucleic acid polymer (NAP) with entry and post-entry antiviral activity against duck hepatitis B virus (DHBV) infection. REP 2055 has been shown to have potent therapeutic effect against established DHBV infection in vivo REP 2055 was additionally shown to have significant antiviral effects in patients with chronic HBV infection in the previous REP 101 study. REP 2139 is a version of REP 2055 designed for improved administration tolerability and stability. The safety and antiviral activity REP 2139, first in monotherapy and then in combination with immunotherapy in patients with chronic HBV infection will be assessed in the REP 102 protocol.
REP 9AC (REP 2055) is a nucleic acid polymer (NAP) with entry activity against hepatitis C virus and entry and post-entry antiviral activity against duck hepatitis B virus (DHBV) infection. REP 2055 has been shown to have potent prophylactic effect against HCV infection in vivo and potent therapeutic effect against established DHBV infection in vivo The REP 101 protocol is the first-in-man proof of concept study designed to investigate the safety and antiviral activity of REP 2055 administration in human patients with chronic HBV or HCV infection.
The study is a phase 2a, single blind, randomized, placebo controlled, study evaluating the safety, anti-viral activity, and pharmacokinetics (PK) following multiple doses of intravenous ARB-001467
To evaluate the safety and tolerability of Hepalatide(L47) and characterize the clinical pharmacokinetics in healthy volunteers.
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.
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.
This study evaluates whether Peg-IFN alfa-2a can reduce the recurrence rate of hepatitis B in 96 weeks after nucleoside analogue (NUC) withdrawal. The HBV HBeAg-Negative patients who received NUC anti-virus treatment for 2.5 years and reached stopping rule in 《Chinese chronic hepatitis B prevention and treatment guidelines》(2010) were randomly assigned into three groups: One group discontinue the NUC treatment and follow up for 96 weeks,One discontinue the NUC treatment ,receive Peg-IFN alfa-2a 180 μg by week for 24 weeks and follow up for 72 weeks,The other discontinue the NUC treatment ,receive Peg-IFN alfa-2a 180 μg by week for 48 weeks and follow up for 48 weeks.
The purpose of this study is to compare the safety and pharmacokinetics of CKD-390(Tenofovir Disoproxil Aspartate) and Viread® tablet(Tenofovir Disoproxil Fumarate) in healthy male volunteers.
Background: Taiwan is one of the area with the highest prevalence of chronic hepatitis B (CHB), and many patients die of hepatitis B virus (HBV)-related cirrhosis or liver cancer that have been the leading causes of death in Taiwan for many years. For effectively treating CHB, antiviral therapy for CHB has been reimbursed by the National Health Insurance in Taiwan since 1998, and nucleos(t)ide analogues (NAs) can be used for patients with active hepatitis B and high viral load in a maximum duration of three years. However, there is a significant proportion of patients suffering from hepatitis B recurrence after discontinuation of NA therapy, and hepatitis B recurrence may result in liver cirrhosis and liver cancer. To the best of current knowledge, in what conditions that the NA therapy can be successfully discontinued without hepatitis recurrence remain largely unclear. Therefore, this study is designed to evaluate the clinical and virological changes of CHB patients after stopping NA therapy, and finding the prognostic indicators may be an important basis for stopping NA therapy in CHB patients in the future. Objectives: 1. To access the clinical and virological changes after stopping NA therapy 2. To determine important prognostic indicators for stopping NA therapy Methods: In this prospective cohort study, the investigators plan to recruit CHB patients who are indicated for stopping NA therapy in the outpatient clinics according to the inclusion and exclusion criteria of this study, and clinical and virological data will be collected during routine clinic visits after stopping NA therapy. Prognostic factors will be analyzed according the following data: 1. Patient characteristics: including age, sex, height, weight, waist circumference, history of alcohol drinking, antiviral therapy history, hepatitis history, and drug history. 2. Blood tests: During routine clinic visits and blood tests every 12 weeks or at hepatitis flare in the first 2 years after stopping NA therapy, liver function and virological status tests will be conducted for analysis.
