Filter by:To evaluate the incidence of grade 3 or 4 transaminase elevations or grade 4 total bilirubin elevations (hepatic toxicity) during the first 48 weeks of antiretroviral therapy with the combination of rilpivirine (25mg), tenofovir (245mg) and emtricitabine (200mg), in a single-tablet regimen (Eviplera®) in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected subjects.
This is a phase IV, single-arm, open-label, multi-centre study to assess the efficacy of TDF in Chronic hepatitis B (CHB) subjects following failure of multiple Nucleos(t)ide analogues (NAs). The study will enrol 200 CHB subjects following failure of multiple NAs. Subjects will be assessed for eligibility at a screening visit, with eligible subjects returning for a baseline assessment after approximately 4 weeks (Screening phase). In the treatment phase all enrolled subjects will receive open label TDF at a dose of 300 milligrams (mg) orally once daily. All the eligible study subjects will undergo safety and efficacy assessments every 12 weeks for a total of 14 visits. Tenofovir disoproxil fumarate, the oral pro-drug of tenofovir (TFV), is a nucleotide analogue that inhibits viral polymerases by direct binding and after incorporation into deoxyribonucleic acid (DNA), by termination of the DNA) chain. TDF is a highly potent treatment in treatment-naïve and lamivudine (LAM) resistant CHB patients. The purpose of our study is to evaluate the efficacy of TDF treatment in Chinese CHB patients following failure of multiple NAs. In addition, the study will also explore the relationship of baseline factors and early HBV DNA suppression to long-term virological response. The efficacy of TDF in multi-drug resistant patients will be analysed separately. The data generated by this study could then be used to optimize the clinical application of TDF and provide new evidence for management of the HBV infections following failure of multiple NAs. The result of this study will help Chinese physicians better manage the CHB patients following failure of multiple NAs.
Background: - The hepatitis E virus causes an acute hepatitis that usually goes away by itself. Researchers in France studied people who received a liver or kidney transplant. They found that hepatitis E may not go away by itself in these people. It becomes chronic. This can cause serious liver disease. More than half the people who had organ transplant who had hepatitis E seemed to get a chronic infection. Researchers want to find out if hepatitis E happens this often in patients who have liver, kidney, or small bowel transplants in the United States. If it does, they want to know why. They want to know if chronic hepatitis E will become an important medical problem. This research might help improve care for people who have a transplant. It also might help researchers prevent the spread of hepatitis E. Objective: - To see how many patients who have received or are waiting for certain transplants have antibodies to hepatitis E virus. Eligibility: - Adults over age 18 who have had a liver, kidney, liver and kidney, or small bowel transplant, or are on a waiting list for one. Design: - Participants will be enrolled from 3 transplant centers. - Participants will complete a questionnaire. They will be asked about possible risk factors for hepatitis E exposure. - Participants will have a blood sample drawn through a needle placed in a vein.
The purpose of this study is to determine the safety and immunogenicity of the recombinant hepatitis E vaccine in people older than 65 years, and evaluate the efficacy of hepatitis E vaccine in this population.
The primary objective of the study is to evaluate the safety and tolerability of voxilaprevir (formerly GS-9857) alone or with sofosbuvir (SOF)/velpatasvir (VEL) fixed dose combination (FDC) and antiviral activity of voxilaprevir in adults with genotype 1, 2, 3, 4 hepatitis C virus (HCV) infection. All participants will be monitored for up to 48 weeks after the last dose.
Subjects are being asked to take part in a research study to test two levels of alcohol services for patients with hepatitis C virus (HCV) who drink alcohol. The two levels differ in intensity of alcohol services and in whether or not they include a focus on liver health. The study will look at which level of alcohol services best decreases alcohol use among patients with HCV.
The purpose of the study is to determine whether the combination of Daclatasvir (DCV), Asunaprevir (ASV), BMS-791325 and Sofosbuvir is effective and safe in treating Hepatitis-C virus.
The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of GS-4774 in adults with CHB and who are currently not on treatment. Participants will be randomized to receive TDF alone or GS-4774 plus TDF for 20 weeks. After Week 20, GS-4774 will be discontinued. All participants will continue on TDF and will be followed for an additional 28 weeks. Following completion of the 48 week study period, all participants will be eligible for a treatment extension for 96 weeks.
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.
To demonstrate the effectiveness of Daclatasvir (DCV) 3 Direct Acting Antivirals (DAA) fixed dose combination in Genotype 1 Chronic Hepatitis C subjects.
