Filter by:The purpose of the study is to investigate the long-term safety and the antiviral activity of the optimal doses of LB80380 for additional 48 weeks in treatment-naive patients with chronic hepatitis B infection compared to entecavir 0.5 mg.
This study will evaluate immune responses in patients with HBeAg-negative chronic Hepatitis B treated with Pegasys (peginterferon alfa-2a). Eligible patients will have been randomized in study ML18253 to receive Pegasys 180 mcg subcutaneously for 48 or 96 weeks. Sample collection period for each patients will occur in the first 24 weeks.
Evaluate the safety and efficacy of Peginterferon alfa-2a following Entecavir compared with Peginterferon alfa-2a monotherapy in patient with HBeAg positive chronic hepatitis B. - Increased HBeAg seroconversion rate - Increased HBsAg loss rate - To define the best treatment condition for chronic HBV hepatitis patients
The overall goal of this trial is to evaluate the efficacy of FG-3019 for reversing liver fibrosis in subjects with chronic hepatitis B infection who are beginning antiviral therapy with entecavir. This Phase 2 randomized, double-blind, placebo controlled study will enroll subjects with chronic active hepatitis B infection and liver fibrosis (Ishak score ≥2) who are eligible for antiviral therapy.
Objective(s) The primary study objective is to assess the antiviral effect of 12 weeks of adefovir dipivoxil treatment in Korean patients with chronic hepatitis B and compensated liver disease. The secondary study objectives are to assess the antiviral effect, clinical benefit and safety of 52 weeks of adefovir dipivoxil treatment. Endpoint(s) The primary efficacy endpoint is "Mean log10 reduction in serum HBV DNA level from baseline to Week 12". The secondary efficacy endpoints include (a) the proportion of patients achieving serum ALT normalization at Week 52, (b) other assessments of antiviral effects (the proportion of patients achieving HBV DNA no less than 300 copies per mL at Week 52), (c)HBeAg loss, HBeAg seroconversion, HBsAg loss and HBsAg seroconversion, (d)the proportion of patients achieving serum ALT normalization at Week 12. Study Design This is an open label, multi centre phase IV study for Korean patients with chronic hepatitis B and compensated liver disease, assessing the antiviral effect of 12 weeks treatment of Adefovir dipivoxil as a primary objective and antiviral effect, clinical benefit and safety of 52 weeks treatment as secondary objectives. Patients will be screened for eligibility criteria and the baseline visit for the treatment initiation should occur no more than 4 weeks after screening. Total treatment period will be 52 weeks and patients will return to the clinic for assessments as scheduled during treatment period. After the 52 week study period, it is likely that the patient will benefit from continued treatment with commercial adefovir. If in the investigator's clinical judgement this is the case, the investigator should ensure that a routine prescription is available in a timely manner, and that no unnecessary interruption in treatment occurs. Study Population A minimum of 100 male or female Korean patients more than 18 years of age with HBeAg positive chronic hepatitis B and compensated liver disease who meet the eligibility criteria will be enrolled. Study Assessments and Procedures Potential patients will be screened prior to study entry and eligible patients who have given their consent will have further baseline assessments. Following the screening, the first doses of study medications will be given at baseline and patients will return to the clinic for assessment as scheduled during treatment period. Patients who discontinue treatment prematurely will be followed up every 4 weeks for 12 weeks following the withdrawal visit. The following key assessment and or measurement will be made at one or more visits during the study. (See section 14.1 Appendix 1. Time and event schedule): - Pregnancy test (females of child-bearing potential only) - Haematology and serum chemistry profile including prothrombin time(PT) and AFP - HBV DNA (Roche COBAS AMPLICOR HBV MONITOR Test, LLOD 300 copies per ml) - Hepatitis B markers: HBeAg(Anti HBe will be tested if HBeAg is negative), HBsAg(Anti HBs will be tested if HBsAg is negative) Investigational Product(s) Adefovir dipivoxil 10mg tablets will be supplied by GlaxoSmithKline and presented as a white to off white, round tablets, packaged in the bottle containing 30 tablets
Patients with HBeAg negative chronic HBV and evidence of hepatic disease (elevated liver enzymes or evidence of cirrhosis) who have significant viremia are treated with anti HBV therapy. Currently the key goals of anti HBV therapy are profound and prolonged viral suppression and treatment efficacy is assessed by monitoring viral load and liver enzymes. However these do not always reflect the degree of liver impairment or the degree of improvement in response to therapy. Sebivo has been accepted in Israel as a first line therapy for HBeAg negative and HBeAg positive chronic HBV with evidence of liver damage. Viral load should decrease by 1 log every 3 months, otherwise patients should be offered add-on or alternative therapy. As the majority of patients in Israel are HBeAg negative chronic HBV and in order to have homogenous population we will select for our study only patients with HBeAg negative chronic HBV. The 13C Methacetin breath test, assess liver function and specifically the function of the microsomal CYP4501A2. It has been shown to correlate with the degree of liver impairment and with clinical outcomes in both acute and chronic liver disease. The aim of this study is to determine the utility of the 13C Methacetin Breath Test to follow up patients with HBeAg negative chronic HBV receiving anti viral therapy.
At least 1 dose of pegIFNλ will be identified which is safe, well tolerated, and efficacious for the treatment of chronic hepatitis B virus infection (CHB) Amendment 7, Part B Sub Study: The primary purpose of this amendment is to obtain preliminary data on the safety of pegylated interferon Lambda (Lambda) when administered in combination with Entecavir(ETV) to patients with hepatitis E antigen-positive (HBeAg-positive) chronic hepatitis B(CHB) infection employing a sequential therapy approach
This study is an expanded Phase 2/Phase 3 clinical trial base on the safety data obtained from the phase 1 clinical trial. The purpose of this study is to further evaluate the immunogenicity and safety of 60mcg/30mcg recombinant hepatitis B vaccines in people aged 16 and older who failed to respond to routine administration of 10mcg recombinant hepatitis B vaccines and to explore the optimizing immunizing dose and immune procedure.
Baseline information indicates there are measurable levels of hepatitis B SAg and low utilization of postpartum contraception, correct breastfeeding practices, or adherence to infant vaccination schedules in Kabul, Afghanistan. This intervention will randomize hospitals to assess the following aims: Aim 1: To determine whether the re-training and assignment of health care providers dedicated to intrapartum rapid testing and post-partum counseling will positively impact maternal and neonatal health indicators as compared to utilization of existing health providers for these services among women delivering in publish health maternity hospitals in Kabul, Afghanistan. Aim 2: To assess whether patients randomized to the intervention and their spouses perceive value in concentrated post-partum counseling. Aim 3: To investigate whether an intervention providing immediate post-partum provision of a long-acting family planning method would be feasible and acceptable to both men and women in Kabul, Afghanistan. Outcomes will be assessed through questionnaire responses and inspection of vaccination cards at six month intervals by trained study staff. The third aim will be addressed at the 12 month follow-up visit.
Phyllanthus Urinaria - Adenosma Glutinosum - Eclipta Prostrata - Ascorbic Acid combination plus Tenofovir in treatment of acute and chronic hepatitis B. Method the combination of drugs derived from natural and artificial medicaments. Has stronger effect on immune system, effective good against HBV replication. This is a substantial new insight into the pathogenesis of disease, with a clear path toward clinical application, or which would lead to a substantial advance and perfect in management or public health policy.
