Active clinical trials for "Hepatitis A"

The aim of the present trial is to evaluate whether the conversion of immunosuppression from tacrolimus to cyclosporine A induces changes in (i) hepatitis C-virus load, (ii) parameters of hepatic function and (iii) parameters of glucose tolerance in hepatitis C-positive renal transplant recipients.

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

No study has reported on the comparative effect of continuing lamivudine plus adefovir versus switching to telbivudine plus adefovir in HBeAg-positive lamivudine-refractory chronic hepatitis B patients who have suboptimal response to lamivudine plus adefovir. The goal of this study is to compare the efficacy of continuing lamivudine plus adefovir versus switching to telbivudine plus adefovir directly in patients with lamivudine-refractory chronic hepatitis B patients who have suboptimal response to lamivudine plus adefovir for at least 12 months.

The purpose of this study is to evaluate if the combination of Lpv/r monotherapy and anti-HCV drugs does not match with additional toxicity induced by the association of HAART and Peg-IFN + ritonavir in HIV/HCV coinfected patients. Secondary objective is to assess if Lpv/r monotherapy during HCV-treatment is associated with HIV efficacy versus optimized HAART.

To preliminarily evaluate the efficiency and safety of therapeutic double- plasmid HBV DNA vaccine on HBeAg-positive, chronic hepatitis B patients, and provide evidence for the next dosing regimen.

Three-parallel-arm, open-label, international (France and Romania) study, comparing three treatments The purpose of this study is to confirm if IFN alfa-2b XL has a better antiviral activity and tolerability as compared with current marketed reference, while combined with ribavirin, in a 3-month therapy setting.

This is a randomized, open label, phase IV, multicenter study for efficacy and safety of lamivudine versus entecarvir therapy in HBV-related advanced liver disease patients with high viral load and normal or slightly elevated transaminase.

Although the best treatment choice for chronic hepatitis B is not clarified yet, certain therapeutic concepts could be derived from the experience of treating patients with chronic hepatitis C or human immunodeficiency virus (HIV) infection. A major advancement in treating hepatitis C or HIV infection has been the development of combination therapy. Whether the combination therapy using Peg-IFN alfa-2a plus ETV can achieve a long-term beneficial effect against ETV alone is not clarified. A prior single-arm pilot study suggested that similar combination therapy may be beneficial in patients with chronic hepatitis B. In this proposal, we thus hypothesize that the efficacy by using combination therapy with pegylated IFN alfa-2a plus ETV is superior to that by using ETV alone in that Peg-IFN may restore host immunity against HBV and prolonged ETV can maximize viral suppression. The objective of this clinical trial is to evaluate the efficacy of the combination of Peg-IFN alfa-2a at a dose of 180 mcg administered subcutaneously per week and ETV 0.5 mg daily for 24 weeks followed by ETV 0.5 mg daily monotherapy for an additional 120 weeks versus ETV 0.5 mg daily monotherapy for 144 weeks in patients with HBeAg-positive chronic hepatitis B. It will be an open-label, randomized, comparative, multi-center clinical trial. The recruited patients will be equally randomized into two treatment groups. Treatment-free follow-up period will be 48 weeks in both groups of patients. All subjects will be assessed for loss of HBeAg, presence of anti-HBe, loss of HBsAg, presence of anti-HBs, suppression of HBV DNA, and normalization of serum ALT at the end of treatment and end of follow-up. Genotypic and virologic resistance to ETV will also be assessed at baseline and at end of years 1, 2 and 3. The primary efficacy will be HBeAg seroconversion.

Combination therapy with pegylated interferon-alpha plus ribavirin has greatly improved the treatment efficacy and is the mainstream of treatment for chronic hepatitis C infection. The efficacy and safety of pegylated interferon-alpha plus ribavirin combination therapy and its impact on the outcome in chronic hepatitis C patients concomitant with hepatocellular carcinoma deserve to be elucidated. The purposes of this study are: To evaluate the efficacy and safety of pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with hepatocellular carcinoma. To investigate the role of baseline and on-treatment factors on the response to pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with hepatocellular carcinoma.

To explore the effect on early viral kinetics and viral load, and to determine safety, tolerability and anti-viral response for the plasmid DNA vaccine CHRONVAC-C administered i.m. in combination with electroporation followed by standard of care (SOC) in treatment naïve chronic HCV genotype 1 patients.
