Filter by:The primary objectives of this study are to describe the efficacy of: 1. 8-week treatment of SOF/LED for treatment-naïve, non-cirrhotic, HCV genotype 6 2. 12-week treatment of SOF/LED for all other HCV-6 populations
The study is a single centre, single arm, open-label, proof of concept study enrolling 20 adult primary liver transplant recipients with genotype 1 HCV infection. Subjects will receive Sofosbuvir (SOF) and Ledipasvir (LDV) starting at time of liver transplantation (OLT) and continues for 12 weeks. Subjects will be receive 24 week post-treatment follow up.
A study to evaluate immune restoration following removal of viral antigen in non-cirrhotic hepatitis C virus (HCV) genotype (GT) 1a treatment-naïve and pegylated-interferon (pegIFN)/ribavirin (RBV) treatment-experienced adults receiving treatment with ombitasvir/paritaprevir/ritonavir and dasabuvir coadministered with ribavirin (RBV) for 12 weeks.
The goal of this study is to evaluate the effectiveness of a brief, computerized behavioral intervention for promoting screening for hepatitis C and reducing risky behavior for people who inject drugs (PWID).
For those chronic hepatitis C patients, who are interferon-ineligible or intolerant, there is a burning need for the development of pan-oral interferon-free regimen. The investigators examine the efficacy and safety of sofosbuvir, a NS5B nucleotide polymerase inhibitor and daclatasvir, an NS5A replication complex inhibitor in Chinese treatment-experienced cirrhosis patients with chronic G1b infection.
This is a 3-arm, multi-center, patient-randomized, field evaluation of the "Way to Cure" behavioral interventions on medication adherence in HCV.
The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) with or without ribavirin (RBV) in adults with chronic hepatitis C virus (HCV) infection.
The study is designed to test the hypothesis that the addition of a protease inhibitor to dual NS5a-NS5B nucleoside prodrug analog will enhance antiviral efficacy and hence shorten the treatment duration to 3 weeks.
The present study evaluates neurocognitive performance as well as measures of mood, quality of life, and fatigue in patients with chronic hepatitis C infection. In a prospective longitudinal study design, included patients are monitored before, during, and in the long-term follow-up of interferon-free antiviral treatment (Sofosbuvir +/-Daclatasvir +/- Ribavirin or Sofosbuvir/Ledipasvir +/- Ribavirin). Main study goals are to compare post therapy results of sustained virologic responders to corresponding pretreatment values as well as to historic interferon-treatment patients without virological response. It is expected that HCV-associated neuropsychiatric symptoms and neurocognitive impairment is - at least in part - reversible by the successful application of modern IFN-free antiviral medication.
Background: - Chronic hepatitis C is a serious liver disease. Current treatments have side effects. New drugs have been developed, but they work better in some people than others. Researchers want to learn why. Objective: - To learn why new hepatitis C drugs sometimes do not work. Also, to learn if these drugs are safe and how well they work in people with different virus strains. Eligibility: - Adults age 18 and older who are infected with hepatitis C virus genotypes 1-4 and who have either never been treated or treated previously with an interferon regimen (with or without ribavirin) that failed to clear the virus. Design: - Participants will be screened with medical history and physical exam. They will have blood and urine tests and complete questionnaires. - Participants will have a Fibroscan, an ultrasound that measures liver stiffness and other liver scans. They will have an electrocardiogram. - Eligible participants will have a liver biopsy. - Participants will be admitted to the Clinical Center. They will have a physical exam and blood tests, and complete questionnaires. - They will take the first study drug dose as a tablet taken once daily. - Participants will take the drug at home for 12 weeks. - Participants will have 6 study visits. They will have blood and vital signs taken, and complete questionnaires. - At week 4, participants will have another liver biopsy. - After their last drug dose, participants will have 5 follow-up visits. They will have blood and vital signs taken, and complete questionnaires. They will discuss their medications and side effects. They may have another Fibroscan.
