Active clinical trials for "Hepatitis A"

Rationale: Current standard therapy of autoimmune hepatitis consists of a combination of prednisolone and azathioprine. However, a significant proportion of patients does not respond to, or is intolerant for, azathioprine. Mycophenolate mofetil (MMF) has surpassed azathioprine as therapy to prevent organ transplant rejection and is sometimes used as an alternative option for autoimmune hepatitis. Several case series and one prospective study have documented the efficacy and safety of mycophenolate mofetil as induction therapy for autoimmune hepatitis. Robust evidence from a formal randomized clinical trial is lacking. Objective: To assess the efficacy and safety of mycophenolate mofetil as induction therapy in patients with treatment naive autoimmune hepatitis. Study design: Multicenter, randomised, open-label intervention study Study population: Patients with newly diagnosed autoimmune hepatitis who are in need of induction therapy according to current guidelines. Intervention: The intervention group will receive oral mycophenolate mofetil for 24 weeks. The control group will be treated with azathioprine for 24 weeks. Both groups will be treated with steroid induction which will closely follow the schedule from the recent Clinical Practice Guidelines by the European Association for Study of the Liver (EASL). Main study parameters/endpoints: The primary outcome is the proportion of patients in biochemical remission, defined as normalization of serum alanine transaminase (ALT) and immunoglobulin G (IgG) levels after 24 weeks of treatment, per treatment group. Secondary endpoints include safety and tolerability of mycophenolate mofetil, time to remission, changes in Model For End-Stage Liver Disease (MELD) -score (and its components bilirubin, INR, creatinine), albumin, pseudocholinesterase and N-terminal procollagen-III-peptide, ELF (Enhanced Liver Fibrosis) -score and aspects of quality of life.

Efficacy and Safety of ibrutinib in patients with chronic lymphocytic leukemia and other indolent B-cell lymphomas who are chronic hepatitis B virus carriers or occult hepatitis B virus carriers

The study objective is to evaluate the safety and effectiveness of different doses of Metacavir Enteric-coated Capsules in treatment of chronic hepatitis B,as well as to find an appropriate clinical dosage by comparing the effect of different doses of treatment,in order to provide references of clinical trial of the next phase.

Ezetimibe possesses pharmacophore features to inhibit NTCP, the receptor required for HBV and HDV hepatocyte entry that include two hydrophobes and one hydrogen bond acceptor. Therapy with Ezetimibe may lead to decline in hepatitis D virus levels. The aim of the study is to evaluate the utility of Ezetimibe in patients with chronic HDV infection

This is a nonrandomized, open-label, no-control, dose-escalation Phase 1b trial in 18 patients with chronic HBV infection to determine the safety, preliminary efficacy, and pharmacokinetics (PK) of QL-007 after administration over 28 days of multiple oral doses in a fasted state at the following planned dose levels: 200 mg/day (100 mg two times a day (BID)), 400 mg/day (200 mg BID), then 600 mg once daily (QD), with 6 patients for each cohort.

This study will evaluate the persistence, immunogenicity and safety of Havrix® (hepatitis A vaccine) in adults primed in infancy. The enrolled subjects will be assessed for circulating antibodies against hepatitis A and will also receive a challenge dose of Havrix Adult vaccine. In the present study, the anamnestic response will be assessed 30 days after the challenge dose.

Chronic Hepatitis B is the most common cause of chronic viral liver disease worldwide afflicting 350 million persons, leading to significant morbidity and mortality due to liver disease and HCC in 20-40% of infected persons. With the advent of nucleoside analogues, this rescued patients with significant risk of disease progression, but in most circumstances, therapy was needed long term as HBsAg seroclearance was an uncommon occurrence, and stopping therapy was associated with relapse of disease and hepatitis B flares. The use of pegylated interferons showed increased HBeAg seroconversion and HBsAg seroclearance rates compared to nucleoside analogues , however combination nucleos(t)ide analogue therapy has been quite disappointing. However a recent showed that the combination of telbivudine and tenofovir in a response guided therapy design, had a remarkable 6% HBsAg seroclearance at week 52 in patients. Such results require further confirmation. There is currently an unmet need for the large number of patients on long term nucleoside analogue therapy who have not achieved HBeAg seroconversion or HBsAg seroclearance. Such patients are seeking alternatives to long term therapy hence an exploration of other therapeutic strategies is attractive. An additional benefit of telbivudine has been the surprising improvement in renal function and this study seeks to examine whether this can improve the renal impairment that may be seen with tenofovir. Our study proposes to examine if the combination of tenofovir and telbivudine can improve endpoints. Patients fulfilling inclusion and exclusion criteria will be randomized to tenofovir or tenofovir and telbivudine (1:1 ratio). The primary endpoint will be a qHBsAg reduction of >1log at week 96, which may predict future HBsAg seroclearance, which is also a secondary endpoint. An additional primary endpoint is increase in eGFR in the combination arm compared to the monotherapy arm. The study aims to enroll 146 patients randomized 1:1 ratio (73:73) patients. Multivariate analysis will be performed of baseline and on-treatment factors that predict the primary outcome.

This study evaluates generic emtricitabine(FTC) in Chinese naive chronic hepatitis B patients. Patients were divided into 2 groups: HBeAg positive Chronic hepatitis B(CHB)group and HBeAg negative Chronic hepatitis B(CHB)group.

This study evaluates generic emtricitabine(FTC) in Chinese naive children chronic hepatitis B patients. Single group of child patients were enrolled, which include HBeAg positive and negative Chronic hepatitis B(CHB)group.

This study evaluates generic emtricitabine(FTC) efficacy and safety in Chinese naive pregnant chronic hepatitis B patients. Single group patients were enrolled to receive emtricitabine till 48 weeks after delivery.
