Filter by:Approximately half of the patients receiving treatment for chronic hepatitis C virus (HCV) infection in the United States have advanced liver disease. Patients with advanced fibrosis/cirrhosis who achieve a sustained virological response (SVR) to treatment and are clinically cured of HCV continue to have an elevated risk of developing hepatocellular carcinoma (HCC). According to guidelines from several professional societies and from the American Association for the Study of Liver Diseases (AASLD), in particular, patients with advanced fibrosis/cirrhosis should undergo life-long bi-annual screening for incident HCC whether they achieve an SVR, or not. The number of patients who need post-SVR HCC screening has risen dramatically in recent years due to the confluence of three factors: Increased screening for HCV, which has allowed more people to realize that they have this often "silent" infection; the availability of safe and highly effective direct acting antiviral drugs (DAAs) for HCV, which has allowed a much higher percentage of treated patients to achieve an SVR; and the long duration of HCV infection in many patients, which has allowed enough time for advanced fibrosis/cirrhosis to develop. To investigate post-SVR patients in the era of DAAs and to promote HCC screening, the objective of this study is to conduct a randomized, unblinded, two-arm prospective intervention trial comparing rates of HCC screening between patients randomized to either personalized patient navigation or automated reminders (e.g. electronic or mailed). Both interventions represent improved care over current standard of care (no patient navigation or automated reminders). There is no evidence to suggest one intervention is better than the other. Healthcare providers who agree to participate in the study will be contacted to confirm the liver disease status of their patients and during the clinical trial the providers of patients in both arms of the trial will be sent reminders about the need to schedule patients for screening visits.
The objectives of the study are to determine the impact of interferon-free treatment for the hepatitis C virus (HCV) on peripheral blood immune cell phenotype and soluble immune-related proteins in blood, while controlling for genetic polymorphisms known to impact HCV-related immune responses, and to determine the impact of the therapy on the emergence of drug-resistant HCV. The study design is informed by the researchers recent investigations of patients receiving HCV treatment. About 4% of patients who had not undergone liver transplantation experienced hepatic decompensating or another serious event. There were several cases of bacterial infection and two cases with elevated markers of autoimmune processes. These events suggest that treatment altered immune responses. About 25% of patients who had undergone liver transplantation experienced hepatic decompensating or another serious adverse event. The long term goal is to understand the pathophysiology of these complications and determine whether HCV treatment can cause an immune reconstitution syndrome in susceptible patients, while improving antimicrobial defenses in others
The purpose of this study is to assess the safety and efficacy of 12 weeks of treatment of ABT-493/ABT-530 (glecaprevir/pibrentasvir) in adults who are post primary orthotopic liver or renal transplant with chronic hepatitis C virus (HCV) infection.
Chronic liver diseases of differing etiologies are among the leading causes of morbidity and mortality worldwide [1]. Chronic liver disease progresses through different pathological stages that vary from mild hepatic inflammation without fibrosis to advanced hepatic fibrosis and cirrhosis [2]. Assessment of the stage of liver disease is important for diagnosis, treatment, and follow-up both during treatment and after cessation of treatment. A liver biopsy is the oldest and most accurate method used to evaluate liver histology and the progression of chronic liver disease. Furthermore, different histological scoring systems have been developed and modified [3]. A liver biopsy is considered the gold standard for assessing liver histology [4]. During the pathological progression of liver fibrosis, excessive amounts of extracellular matrix build up; furthermore, serum levels of various biomarkers change, in addition to the appearance of new biomarkers in the serum during the different stages of fibrosis [2, 5]. Recently many noninvasive markers (NIMs) for assessing liver fibrosis have been developed, and they are frequently used in clinical practice. They have been validated in different studies, and some were found to be highly accurate in the assessment of liver fibrosis compared with liver biopsies [6-7], which have always been used as the standard reference method for evaluating the accuracy of noninvasive methods. There are limited studies documenting the cost effectiveness of non invasive markers over invasive technique. Most people with chronic Hepatitis B or C are unaware of their infection, putting them at serious risk of developing cirrhosis or liver cancer which are life threatening. Similarly patients with non alcoholic fatty liver diseases are unaware about fibrosis in liver. About 20-50% of persistent infection ends up into fibrosis and finally cirrhosis. Invasive and non invasive diagnostic methods are widely used to detect the fibrosis. Clinicians use different drugs and combinations to treat HBV and HCV infections. However, there is scarcity of a longitudinal prospective study to assess the cost effectiveness of these diagnostic measures. We planned to conduct a retrospective followed by prospective cohort study among all cases that underwent biopsy in ILBS or GB Pant Hospital since 2000 till Dec 2020 with HBV infection, HCV infection, or non alcoholic fatty liver disease. For retrospective cohort study, we will collect data from hospital information system for all patients with HBV infection, HCV infection, or non alcoholic fatty liver disease, who underwent biopsy during the period of 2000-Dec 2015. The new patients with HBV infection, HCV infection, or non alcoholic fatty liver disease who will undergo biopsy during the period Jan 2016- Dec 2020 will serve as a cohort for prospective design. We will collect socio-demographic data, clinical data, family history, personal history, medical history, anthropometry, biochemical and radiological data from each patient. We will also be conducting a cost effective analysis for various non invasive markers against biopsy as a gold standard in predicting fibrosis, both for retrospective and prospective cohorts. For prospective cohort study, after evaluation of baseline biopsy results, the cases with metavir fibrosis score (F0-3) will be followed for a period of 5 years to document incidence of development and progression of fibrosis. No additional investigation or test will be asked to the patient for the study. We will also develop a predicting model for development and progression of fibrosis.
This study seeks to evaluate the efficacy and safety of ABT-493/ABT-530 in participants with Genotype 1 hepatitis C virus infection without cirrhosis
Long Term Observational Extension Study Designed to Monitor Long-Term Efficacy and Safety of Miravirsen Sodium in Combination with Telaprevir and Ribavirin in Subjects with Chronic Hepatitis C Virus Genotype 1 Infection
The purpose of this study is to assess the efficacy and safety of ABT-493 and ABT-530 with or without ribavirin (RBV) in participants with chronic hepatitis C virus, (HCV)-infection who previously failed treatment with a direct acting antiviral (DAA)-containing regimen.
This study evaluates the efficacy and safety of ABT-450/r/ABT-267 with RBV in treatment-naive and treatment-experienced HCV GT4 subjects without or with compensated cirrhosis.
The purpose of this Phase 2, open-label, 2-part, multicenter study was to evaluate the efficacy, safety, and pharmacokinetics of co-administration of ABT-493 and ABT-530 with and without ribavirin (RBV) at different doses in chronic Hepatitis C virus (HCV) Genotype 1 (GT1), Genotype 4 (GT4), Genotype 5 (GT5), and Genotype 6 (GT6) infection with compensated cirrhosis (GT1 only) or without cirrhosis (GT1, GT4, GT5, or GT6). Although RBV was initially planned in the protocol, it was not administered in any of the study arms.
This proof of concept study is designed to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of TD-6450 in treatment naïve subjects with GT-1, GT-2 or GT-3 chronic HCV.
