Active clinical trials for "Hepatitis A"

The 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.

This 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.

This 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.

Hepatitis 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.

The 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.

The 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.

The 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.

Vitamin 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

The primary objective of this study is to evaluate the safety and tolerability of ascending doses of Hanferon™ in combination with ribavirin (RBV). The secondary objective of this study is to define the PK and PD of ascending doses of Hanferon™ in combination with RBV. The exploratory objective of this study is to make a preliminary assessment of Hanferon™ efficacy in combination with RBV.

The purpose of this study is to determine the effects of silymarin on outcomes of patients with hepatitis C.
