Active clinical trials for "Hepatitis A"

The purpose of this study was to assess the safety, pharmacokinetics, and 4-week rapid virologic response (RVR) of 3 different doses of ABT-267 (also known as ombitasvir) in combination with pegylated interferon/ribavirin (pegIFN/RBV) compared with pegIFN/RBV alone (ABT-267 placebo) in treatment naïve, hepatitis C virus (HCV), genotype 1-infected participants.

The purpose of this study is to investigate the effectiveness and safety of TMC435 compared with placebo in patients who are infected with genotype 1 hepatitis C virus who relapsed after previous interferon-based therapy. Patients will also receive peginterferon alfa-2a and ribavirin as part of their treatment.

In this randomized, cross-over, open label study the correlation of Pegasys (peginterferon alfa-2a) pharmacokinetics after intravenous (iv) and subcutaneous (sc) administration with viral load and viral kinetics will be investigated in patients with chronic hepatitis C genotype 1 who were non-responders to previous standard combination therapy with pegylated interferon and ribavirin. Patients will be randomized to receive either weekly or twice weekly Pegasys iv or sc for 2 weeks, crossing over to the other mode of administration after a washout period of 6 weeks.

Telbivudine reduces DNA and normalizes alanine aminotransferase levels (ALT) in chronic hepatitis B patients with few adverse effects, but its use during pregnancy has not been explored. In this open-label, prospective study from the second trimester to post-partum week 28. This trial is to study the efficacy, safety and tolerability of Telbivudine in HBeAg Positive Chronic Hepatitis B Pregnant Women with high level of serum HBV DNA and elevated alanine aminotransferase levels.

The aim of this study was to evaluate the immunogenicity and safety of the Quinvaxem vaccine (a liquid combination vaccine against diphtheria, tetanus, B. pertussis, hepatitis B and H. influenzae Type B). Healthy Vietnamese infants received three doses of vaccine at 2, 3 and 4 months of age according to the local Expanded Programme on Immunisation (EPI) schedule

The primary objective of this study is to evaluate the efficacy of tenofovir disoproxil fumarate (TDF) plus peginterferon α-2a (Peg-IFN) combination therapy for 48 weeks versus standard of care TDF monotherapy or Peg-IFN monotherapy for 48 weeks in non-cirrhotic adults with chronic hepatitis B virus (HBV) as determined by loss of hepatitis B surface antigen (HBsAg). The study will consist of 2 phases for participants in the TDF+Peg-IFN 48 Weeks, TDF 48 Weeks + Peg-IFN 16 Weeks, and Peg-IFN 48 Weeks groups. Following an initial 48 weeks of treatment, participants in these groups will be monitored for 24 weeks for signs of worsening HBV, and those meeting TDF retreatment and flare management criteria will be eligible to receive TDF monotherapy during a retreatment phase, up to Week 120.

This phase 2b study will evaluate the efficacy and safety of 16 and 24 weeks of a 4-drug regimen with GS-9451 and Tegobuvir and 24 weeks of a 3-drug regimen of GS-9451 without Tegobuvir, all with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®).

The purpose of this study is to determine the safety and efficacy of treatment using a combination of drugs (entecavir and pegylated interferon) in children ages 3-<18 years old with immunotolerant chronic hepatitis B.

This is a study of the safety and efficacy of grazoprevir (MK-5172) in combination with elbasvir (MK-8742) ± ribavirin (RBV). The primary efficacy endpoint will be Sustained Virologic Response 12 weeks after the end of all study therapy (SVR12) in each of the treatment arms.

The purpose of this study is to explore the efficacy and safety of TMC647055, TMC435, and low-dose ritonavir, administered together with and without ribavirin and of TMC647055, TMC435, low-dose ritonavir administered together with GSK233680k without ribavirin in a limited number of patients with chronic hepatitis C virus (HCV) infection.
