A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Patients With HBeAg Positive Chronic Hepatitis...
Hepatitis BChronicThis study will evaluate the efficacy and safety of PEGASYS (peginterferon alfa-2a) in patients with HBeAg positive chronic hepatitis B. Patients will be stratified into group A (treatment naïve patients) or B (YMDD mutant patients). All patients will receive PEGASYS 180 micrograms subcutaneously once weekly for 48 weeks, followed by 24 weeks of treatment-free follow up.

This Trial Evaluates Safety, Pharmacokinetic Profile and Anti-viral Response of BI 207127 and BI...
Hepatitis CChronicThe objective of this trial is to investigate tolerability, safety, pharmacokinetics and antiviral activity of BI 207127 NA in combination with BI 201335 NA and ribavirin for 8 weeks in Japanese treatment-naive patients with chronic GT-1 HCV infection.

Tenofovir in Chronic Hepatitis B With Mild ALT Elevation
Chronic Hepatitis BThis study aims to clarify whether patients with chronic hepatitis B with high viral load will benefit from oral antiviral therapy despite only mildly elevated serum liver enzyme.

GS-5885, GS-9451, Tegobuvir and Ribovirin in Treatment-Experienced Subjects With Chronic Genotype...
Hepatitis CChronicThis is a Phase 2 Randomized, Double-Blind, Placebo-Controlled Study of GS-5885, GS-9451, Tegobuvir and Ribavirin (RBV) Compared with GS-5885, GS-9451 with Tegobuvir or RBV in Treatment-Experienced Subjects with Chronic Genotype 1a or 1b Hepatitis C Virus (HCV) Infection.

Evaluating the Safety of ITX 5061 in Treatment-Naive Hepatitis C (HCV)-Infected Adults
Hepatitis CHepatitis C (HCV) is a disease that affects the liver. ITX 5061 is a new medication that is being tested to treat HCV. This study will evaluate the safety of ITX 5061 and examine different doses of the medication to evaluate which dose is the most effective at lowering the amount of HCV in the blood.

Study of the Impact of Nitazoxanide on Chronic Hepatitis Patients
Hepatitis CThe main objective of antiviral therapy of patients with chronic hepatitis C (CHC) is the sustained elimination of the hepatitis C virus (HCV). The standard of care (SOC) is peginterferon alfa-2a/-2b with ribavirin for 48 weeks or 24 weeks according to HCV genotype. However, this approach is not sufficient to substantially improve the sustained virologic response (SVR) rates. Therefore, new therapies are needed to treat patients with hepatitis C virus (HCV) infection. Nitazoxanide (NTZ), originally used to treat cryptosporidium parvum infection, recently was shown to have an unexpected antiviral activity in the HCV replicon system and in chronically infected patients. The aim of this work is to study impact of nitazoxanide therapy in addition to peginterferon/ribavirin combination on virologic responses in patients with chronic hepatitis C genotype 4. Patients will be enrolled in this study and will be randomly assigned in a 1:1 ratio into 2 groups: Group A: comprises 100 CHC patients who will receive the standard of care treatment, peginterferon-alf 2a plus weight-based ribavirin for 48 weeks. Group B: comprises 100 CHC patients who will receive nitazoxanide monotherapy at a dose of 500 mg twice daily for 12 weeks as a lead-in phase followed by triple therapy, nitazoxanide 500 mg twice daily plus peginterferon alfa-2a, and weight-based ribavirin for 48 weeks. Data will be collected and statistical analysis will be done comparing the groups regarding response to antiviral therapy. Final results will be discussed and compared to similar studies published in peer reviewed journals and international conferences.

Adefovir Plus Vaccination in Transplant Patients Without Hepatitis B That Receive a Core Antibody...
Hepatitis BLiver TransplantationThe primary purpose of this study is to evaluate the efficacy of adefovir (ADV) in preventing de novo Hepatitis B in patients who receive Hepatitis B core antibody (HBcAb) positive grafts but who are not Hepatitis B Surface antigen (HBsAg) positive prior to transplant (Hepatitis B naive patients). The second objective is to evaluate the efficacy of accelerated vaccination with Hepatitis B in inducing innate immunity, thereby obviating the need for life-long antiviral therapy.

Pegaferon and Ribavirin for Hepatitis C
Hepatitis CThe purpose of this study is to evaluate the safety and efficacy of a locally produced 40KD pegylated interferon alpha-2a (Pegaferon) in patients with hepatitis C. 100 patients will be treated using standard guidelines for hepatitis C. Response to treatment and side effects will be recorded.

Efficacy of Vitamin D on Top of Pegylated Interferon and Ribavirin in Patients With Chronic Viral...
Chronic Hepatitis CVitamin D deficiency is commonly found in patients with chronic hepatitis C. The investigators hypothesize that the correction of hypovitaminosis D before the initiation of anti-HCV combination therapy and the maintenance of an optimal vitamin D status during antiviral therapy could improve the antiviral efficacy

Ribavirin Loading Dose or Priming and Concentration Targeting for HCV Genotype 1
Hepatitis CThis is a randomized, open-label, parallel group, multicenter pilot study evaluating the efficacy and safety of alternative dosing of ribavirin vs. standard of care dosing in combination with peginterferon alpha-2a in interferon naïve patients with chronic hepatitis c genotype 1 infection.
