Filter by:This is a study of grazoprevir (MK-5172) + elbasvir (MK-8742) and sofosbuvir (SOF) in treatment-naive participants with chronic hepatitis C (HCV) genotype (GT) 1 or GT3. The objective is to determine the proportion of participants achieving sustained virologic response 12 weeks after ending study treatment (SVR12).
The West African Treatment Cohort for Hepatitis B (WATCH) study is a component of the European Commission Funded FP7 project PROLIFICA. It aims to evaluate a number of steps required to successfully treat patients with chronic hepatitis B virus infection to prevent cirrhosis and liver cancer. The first step is to determine whether screening for hepatitis B using a point of care test is feasible and effective. The second is to monitor linkage from screening into care. The third is to evaluate cheap non-invasive assessments to determine the need for treatment. The fourth is to determine what proportion of patients meet treatment eligibility criteria. The fifth step is to establish a treatment cohort which can be used to measure adherence to therapy and avoidance of HBV related complications. A parallel untreated cohort will be established to determine whether treatment criteria are relevant in this West African setting by monitoring for complications of HBV infection.
Infection by hepatitis C virus (HCV) affects more than 170 million people in the World and 80.000 in Chile. It causes more deaths than HIV infection in the US and is a leading cause for liver transplantation in Chile. Even though treatments are evolving with new direct antiviral agents (DAAs) that are increasing response rates, there are several issues with these new approaches, including increased toxicity, need for using interferon and ribavirin, complex algorithms of treatment, high cost, limited effectivity in certain groups (liver transplant patients) and drug interactions. Treatments targeted at host factors required for the viral cycle are becoming increasingly explored as an alternative or complement to DAAs. It has been recently described that Niemann-Pick C1-like 1 (NPC1L1), the intestinal receptor of cholesterol, serves as an entry factor for HCV. NPC1L1 is, therefore, a key transporter in the enterohepatic cycle of cholesterol. NPC1L1 can be blocked with ezetimibe, which is an approved and generally safe drug used for the management of hypercholesterolemia. Our hypothesis posits that blocking HCV entry to the hepatocyte or intestinal HCV reabsorption with ezetimibe may have an antiviral effect. In the study, we will administer ezetimibe 20 mg/d to 20 patients with stable chronic hepatitis C for 12 weeks and assess changes in HCV RNA and core antigen in plasma, bile and feces.
An exploratory clinical trial to evaluate the pharmacokinetic characteristics of I.V. Hepabig injection used for prevention of hepatitis B relapse after liver transplantation.
The purpose of this study is to assess the long-term persistence of immunity to hepatitis A in adults who were vaccinated 21-25 years earlier with hepatitis A vaccine, Havrix®.
The purpose of this study is to demonstrate that the proportion of treatment-naive non-cirrhotic subjects with Genotype (GT)-1b treated with Daclatasvir (DCV)/Asunaprevir (ASV)/BMS-791325 who achieve Sustained Virologic response (SVR12), defined as Hepatitis C virus (HCV) RNA < LOQ target detected or target not detected (LOQ TD/TND) at follow-up Week 12, is significantly higher than SVR12 of current Standard of Care (SOC).
The Birth-Cohort Evaluation to Advance Screening and Testing for Hepatitis C (BEST-C) compares the effectiveness of the birth cohort HCV screening strategy with the current risk-based screening approach to detect previous unidentified persons with viral hepatitis C who receive health care in primary systems. The study involved three clinical sites, The University of Alabama, Birmingham; The Henry Ford Health System; and the Mount Sinai Medical Center, each of which developed an independent intervention to experimentally compare the number of positive Hepatitis C Virus (HCV) diagnoses found using the birth-cohort screening approach with that found using traditional risk-based screening, or standard of care strategies. Birth cohort testing is defined as the systematic recommendation of HCV antibody testing to any persons born during the years of 1945 to 1965 who do not have clinically documented evidence of a prior antibody test without regards to the patient's stated risk of exposure to the virus.
The purpose of this study is to evaluate the effectiveness of the supplementation of vitamins D and B12 in combination with Pegylated Interferon-Alfa and Ribavirin in the treatment of genotype 1 chronic hepatitis C, who do not qualify to receive protease inhibitor in Brazil.
This prospective, national, multicenter, non-interventional study will examine the use of triple combination therapy with boceprevir, Pegasys and ribivarin in re-treating patients with genotype 1 CHC infection. Dosing and treatment duration are at the discretion of the investigator in accordance with local clinical practice and local labeling. Patients will be observed for the duration of their triple combination therapy and for up to 24 weeks thereafter.
Background: - Hepatitis C is a liver disease caused by the hepatitis C virus. It is the most common cause of serious liver disease in the United States. Many people have few if any symptoms. It can lead to cirrhosis, which can cause liver failure and cancer. Researchers want to study how a medicine called chlorcyclizine works in patients with hepatitis C. They want to see if it can be used to treat hepatitis C alone or when used with the standard hepatitis C treatment drug ribavirin. Objectives: - To see if chlorcyclizine can be used to treat hepatitis C alone or in combination with the drug ribavirin. Eligibility: - Adults with chronic hepatitis C who either have never been treated for it or have relapsed after prior treatment. Design: - Participants will be screened with medical history, physical exam, blood and urine tests, and a questionnaire. They will also have an ultrasound of their abdomen and electrocardiogram. Some of these tests will be repeated throughout the study. - Participants will spend 3 days as an inpatient to be monitored while starting study drug. They will be assigned randomly to a group and will begin taking the study drug. Blood will be taken frequently. - Group I will take the study drug twice a day for 28 days. - Group II will take the study drug twice a day and ribavirin twice a day for 28 days. - Participants will visit the clinic every 7 days for 28 days. - After participants stop taking the study drug, they will have 5 follow-up visits over 3 months.
