Active clinical trials for "Hepatitis, Chronic"

The study is aimed to investigate the safety, tolerability and efficacy of a fixed dose combination therapy of: Hydroxychloroquine (HCQ), Pegylated Interferon Alpha-2a (PEG-IFN alpha-2a) and Ribavirin (RBV) in Chronic Hepatitis C Genotype 1 Infected adult subjects who failed to respond following a course of PEG-IFN and RBV Therapy.

Study Purpose: The purpose of this study is to assess that Liquid Acupuncture(Herb Acupoints Injection) Therapeutics could achieve permanent efficacy response in Chronic Hepatitis B. Efficacy Assessment: At cessation of the Treatment(about at 24 weeks)comparing Testing Data with the Normal Criteria and their individual baseline.Continue for monitoring the Status 1-5 years. Data Analysis: Each 4 weeks collecting Patients' testing data and fill a table.A summary table will be presented as frequency tables for categorical variables as number or percentage.

The general objective of the present clinical trial is to compare the therapeutic efficacy of a combination therapeutic vaccine containing hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg) [later called NASVAC] with a commonly used antiviral drug, pegylated interferon in patients with chronic hepatitis B (CHB).

Entecavir(ETV) plus Tenofovir Disoproxil Fumarate(TDF) combination will show effective antiviral activity and prevent further development of antiviral resistance in hepatitis B e antigen(HBeAg)-positive or -negative Chronic Hepatitis B(CHB) patients who experienced multidrug resistance All subjects will orally take investigational drugs once daily for 48 weeks. All subjects will be assessed at baseline, Week 4, 12, 24, 36 and 48. Evaluations at each visit will include vital signs, physical examinations, laboratory tests and HBV DNA levels. They were also questioned about adverse events and concomitant medications. At baseline and every six months thereafter, serum will be assayed for HBV serology. Genotypic analysis will be performed at baseline and 48 weeks.

In order to study the immunotherapeutic effects of electroporation (EP)-mediated dual-plasmids Hepatitis B Virus DNA vaccine, the investigators plan to conduct a double-blind, randomized, placebo-controlled trial, approved by Chinese State Food and Drug Administration with written informed consent from each chronic hepatitis B (CHB) patients with baseline ALT more than 2 times the ULN, for whom antiviral treatment is indicated and who were under the simultaneous lamivudine (LAM) chemotherapy.

The treatment of choice for chronic hepatitis D is uncertain. The investigators hypothesize that pegylated interferon (IFN) alfa-2b in combination with ribavirin (RBV) may be effective in the treatment of chronic hepatitis D patients who are also infected by hepatitis B virus (HBV). The purpose of this study is to test this hypothesis. The investigators will use pegylated IFN alfa-2b in combination with RBV for the treatment of patients with dual chronic hepatitis D virus (HDV) and HBV infection. A 24-week course of combination therapy pegylated IFN+RBV will be used.

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.

This study will evaluate the technical feasibility of using fine needle aspiration (FNA) of liver tissue to obtain vaniprevir (MK-7009) liver pharmacokinetic (PK) data, working towards identifying a minimally invasive, reproducible platform to measure liver PK. The study will be done in 2 parts. In Part 1, participants will be randomized to one of five FNA/core needle biopsy (CNB) time-point collection sequences. In Part 2, participants will be randomized to one of two possible doses of vaniprevir and will be assigned to one of five FNA/CNB time-point collection sequences; participants in Part 2 will also receive background therapy with pegylated interferon alpha-2b (Peg-IFN alpha-2b) and ribavirin (RBV). The primary hypothesis is that there is a greater than 80% posterior probability that vaniprevir concentrations are successfully obtained at least 60% of the time from FNA liver samples collected at 2 of 3 specified timepoints.

The purpose of this study is to assess the loss of HbsAg after a 48-week pegylated interferon alpha 2a in patients with chronic hepatitis B (HBeAg negativation)

The rapidly progression of the disease in HIV-HCV co-infected patients justify the treatment. Combination of Peg interferon and Ribavirin is the best treatment because it improve the compliance of treatment. In APRICOT study genotypes 2 and 3 patients received 48 weeks and the rates of end of treatment response was 64% and the sustained virological response (24 weeks after the end of treatment) 62%. In mono-infected patients trials showed there are not differences in the sustained virological response between 24 and 48 weeks of treatment, however exit the doubt concerning the different kinetic viral in HIV-HCV co-infected patients and this could be related with a lost of profit with a shorter duration of treatment, only 24 weeks. In this study we woud like to evaluate if 24 weeks of treatment in HIV-HCV co-infected patients genotype 2 or 3 will have the same rate of clearance of virus at the end of follow-up period.
