Filter by:Although infection with the hepatitis C virus (HCV) can result in acute hepatitis; it more commonly progresses to chronic hepatitis. The acute process is most often asymptomatic. Acute HCV typically leads to chronic infection. Chronic HCV infection is usually slowly progressive. Approximately 5 to 20 percent of chronically infected individuals develop cirrhosis over a 20-30 year period of time. Chronic HCV is the most common cause of chronic liver disease, cirrhosis, hepatocellular carcinoma, and the most frequent indication for liver transplantation in the United States. Screening for chronic HCV infection is crucial because chronic HCV infection is often asymptomatic, effective treatment is available, and untreated disease carries a high risk of morbidity and mortality. Expert opinion, recommendations, and guidelines for HCV screening do not all agree. All guidelines recommend screening patients at increased risk for HCV (ie: typical risk factors). In 2012, the Centers for Disease Control and Prevention (CDC) recommended screening all persons born between 1945 and 1965. At least two studies suggest that screening persons born between 1945 and 1964 or 1946 to 1970, respectively, is cost-effective. The studies estimated that if patients found to be HCV positive were treated with pegylated interferon, ribavirin, and direct acting antiviral therapy (for patients with HCV genotype 1), it would cost $35,700 to 37,700 per quality adjusted life-year. Screening based upon a birth cohort in patients without risk factors may lead to more false positive results. Currently only 1 % of patients in the birth cohort of 1945-1965 who cared for by Intermountain Healthcare providers have been screened. Ambulatory care physicians are not effectively screening patients. It is unclear whether screening based on risk factors alone versus screening based upon risk factors and birth cohort most effectively manages the burden of chronic HCV infection for patients managed by Intermountain Healthcare providers. It is possible that the Intermountain Healthcare population differs in risk from the U.S. population,making guideline application less certain. A well-designed prospective cohort study is needed to understand the risks and benefits of different HCV screening strategies on diagnostic yield and clinical outcomes. The investigators hypothesize that screening based on a person's history of risk factors will detect chronic HCV infection in 2.7 % of the population tested; this would be according to national average. The investigators further hypothesize that screening based on birth cohort and risk factors will identify roughly the same percentage in the tested population. The investigators anticipate usable data within three months which should give us data to describe and publish the effectiveness of different screening strategies. The investigators will identify patients with chronic HCV infection through this initial study who now require treatment and management. The investigators believe this group could be followed inexpensively for clinical endpoints for many years. This would then definitively define the effectiveness of screening strategies based on good evidence. No study has evaluated clinical outcomes associated with the different screening strategies for chronic hepatitis c virus infection.
The purpose of the study is to determine the safety, pharmacokinetics and efficacy of orally administered VX-135 with ribavirin in treatment naive subjects with chronic hepatitis C infection.
This is an Open-label Phase 3 study in adults with chronic genotypes 1, 2, 3, and 4 HCV infection who are co-infected with HIV-1.
To conduct the following evaluations in Korean healthy male adult volunteers receiving a single and multiple doses of MP-424 tablets: - Pharmacokinetics of MP-424 after a single and multiple doses. - Safety and tolerability of single and multiple doses of MP-424.
1. A maximally tolerated dose of ribavirin can be defined in each patient with ESRD undergoing hemodialysis. 2. Patients with Chronic Hepatitis C Virus (HCV)and End-Stage Renal Disease (ESRD)undergoing hemodialysis will be able to tolerate and remain on treatment with peginterferon alfa-2b, the maximally tolerated dose of ribavirin and boceprevir. 3. A significant percentage of patients with chronic HCV and ESRD undergoing hemodialysis can achieve rapid virologic response (RVR), extended virologic response (eRVR) and sustained virologic response (SVR) when treated with peginterferon alfa-2b, the maximally tolerated dose of ribavirin and boceprevir.
A Phase 2 study to evaluate the safety and efficacy of two different once daily doses VX-135 in combination with ribavirin in treatment-naïve subjects with chronic hepatitis C
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.
The purpose of this study is to examine the feasibility, safety, and effectiveness of treating persons who are actively using illicit drugs for hepatitis C using a collaborative, multidisciplinary, integrated care model. We hypothesize that by maximizing facilitators and minimizing barriers to treatment we can enable drug users to receive effective treatment for hepatitis C.
The purpose of this study is to determine the effect of renal impairment on pharmacokinetics (PK) of BMS-914143.
This study will examine viral dynamic responses in subjects with chronic hepatitis C and hemophilia when treated with pegylated interferon + ribavirin and telaprevir.
