Active clinical trials for "Hepatitis A"

Background: - Some people who have chronic hepatitis C do not respond to the usual treatment with peginterferon and ribavirin. New chronic hepatitis treatments are being developed that may work better for different people. The treatments will look at how specific genes interact with the drugs. Researchers want to see how well these new drugs work in people whose chronic hepatitis C has not responded or only partly responded to the usual treatment drugs. Objectives: - To compare new treatments for people with chronic hepatitis C. Eligibility: - Individuals at least 18 years of age who have chronic hepatitis C that has not responded to standard treatments. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Liver scans and a biopsy will be taken before the start of treatment. Participants will be separated into two groups. One group will have the new treatment drugs (assunaprevir and daclatasvir). The second group will have these two drugs as well as peginterferon and ribavirin. All participants will have an initial 4-day hospital stay with regular blood tests to see how the start of the treatment works. The first group will take the new study drug tablets daily for 24 weeks. Those who do not respond to this treatment will also start to take peginterferon and ribavirin, and the treatment will continue for 24 weeks after starting the additional drugs. The second group will take all four drugs according to the standard dosing schedule for 24 weeks. Treatment will be monitored with frequent blood tests. Liver scans, biopsies, and other tests will be performed as directed by the study doctors. Participants will have 24 weeks of regular followup visits.

The purpose of this study is to investigate the efficacy and safety of medical ozone in treatment of chronic hepatitis B patients.

This study will provide a rationale for switch from lamivudine plus adefovir to tenofovir monotherapy in Lamivudine plus Adefovir Treated Lamivudine-resistant chronic hepatitis B patients with Undetectable Hepatitis B Virus DNA

To determine whether response guided treatment with pegylated interferon +/- ribavirin is effective for the treatment of recently acquired hepatitis C infection. Response guided treatment is when the length of treatment is determined by how quickly you respond to the treatment.

The objective of this trial is to collect evidence for the safety and efficacy of 24 weeks of treatment with BI 201335 240 mg in combination with 24 or 48 weeks of Pegylated Interferon (PegIFN) and ribavirin (RBV) in treatment experienced patients who have been withdrawn from PegIFN and RBV treatment due to lack of efficacy in the 1220.7, 1220.30 and 1220.47 trials.

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 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 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 purpose of this study is to evaluate the antiviral activity, safety, and pharmacokinetics of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-333 (also known as dasabuvir) and ribavirin (RBV) in treatment-naïve and non responder participants with genotype 1 chronic hepatitis C virus (HCV) infection.
