Active clinical trials for "Hepatitis A"

The purpose of this early access program is to provide telaprevir to patients with a specific type of hepatitis C viral infection (termed 'genotype 1') who are expected to benefit from telaprevir-based therapy but who reside in countries in which telaprevir is not yet commercially available and who are not eligible for enrollment into a clinical study of telaprevir. The study also aims to collect information on the safety and adverse events with telaprevir treatment in combination with peginterferon alfa and ribavirin, which is typically used to treat patients with hepatitis C. In addition to hepatitis C viral infection, patients in this study will also have a diagnosis of liver fibrosis and compensated liver disease.

The purpose of this study is to monitor the cardiovascular and renal health of patients who previously took BMS-986094 (an investigational medication for hepatitis C) in comparison to hepatitis C infected patients who have never taken BMS-986094.

This Phase 4 study is designed for the collection of blood biomarker samples from participants who have completed CHB treatment with at least 24 weeks of a pegylated interferon alfa-2a (Peg-IFN alfa-2a) containing regimen and at least 24 weeks post-treatment follow-up. Participants may be enrolled from historical studies supported or sponsored by Roche, ongoing studies supported or sponsored by Roche, or from general medical practice. The follow-up of individuals who choose to participate in this study will be in accordance with the ongoing studies or with the general medical practice of the physician. Data from whole blood deoxyribonucleic acid (DNA) samples collected in the GV28555 study or available from previously collected Roche Clinical Repository (RCR) samples will be used for combined analysis with data from other applicable studies. Procedures will include blood sample collection (not applicable for participants who previously have consented and donated RCR DNA samples) and medical record capture.

This study is being conducted to assess the risk of hepatitis B (HepB) diagnosis among diabetes mellitus (DM) and non-DM patients of 0-80 years of age with in a large population-based cohort in United Kingdom (UK) using data from the CPRD database.

This trial studies hepatitis B screening strategies of new cancer patients scheduled to undergo chemotherapy. Patients with cancer and hepatitis B virus infection are at risk of reactivation of infection after chemotherapy. Hepatitis B virus infection reactivation can be prevented by starting antivirals before chemotherapy in patients who are hepatitis B virus infection positive. Hepatitis B screening may help doctors prevent the reactivation of hepatitis B virus infection after chemotherapy.

Define the patients who lost HBsAg, studying the loss predictive factors and if there was suspension of treatment, study the evolution after that

This non-interventional clinical study will be conducted to prospectively collect serial plasma and serum samples from treatment naïve subjects with chronic HCV infection who are initiating sofosbuvir-based therapy. These samples will be used to estimate clinical utility endpoints for the Aptima HCV Quant Dx assay which is used an aid in the management of HCV-infected patients undergoing HCV antiviral therapy.

Purpose: To improve the diagnosis and assessment of severity of acute alcoholic hepatitis Participants: Patients admitted to one of ten centers with acute alcoholic hepatitis Procedures (methods): Consecutive patients admitted with acute alcoholic hepatitis will be enrolled in an NIH U01 study of acute alcoholic hepatitis where liver tissue, blood and stool will be collected to discover and validate factors associated with diagnosis, severity of disease and survival.

To conduct a prospective, multicenter, observational study of patients with well-characterized alcoholic hepatitis (AH) and frequency matched individuals (by age, gender, and race) with comparable history of alcohol consumption but no clinical evidence of liver disease (controls). At the end of the study, a robust clinical information, central bio-repository will be developed from both cases and controls.

This is an observational prospective follow-up study to assess the utilization of boceprevir and the management of pre-specified health outcomes of interest (HOIs) under conditions of routine clinical care in participants with chronic hepatitis C (CHC) genotype 1. As an observational prospective study, this study is not intended to change the participant/physician relationship, nor influence the physician's drug prescription or therapeutic management of the participant. No individual administration of any therapeutic or prophylactic agent is assigned in this protocol, and there are no procedures required as part of this protocol. Physician choice of the drug used to treat the participant is based on clinical judgment alone.
