Filter by:The primary objectives of this study are to evaluate the safety and efficacy of treatment with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) in adults with chronic hepatitis C virus (HCV) infection who have previously received treatment with direct-acting antiviral therapy. Participants randomized to placebo may be eligible for deferred treatment with active SOF/VEL/VOX.
People who are infected with Hepatitis C Virus (HCV) have a great chance of being cured of the infection when they are treated with sofosbuvir. However, in some instances, treatment with sofosbuvir-containing therapy does not work. It is not known if people respond to retreatment with sofosbuvir, after it did not work the first time. There is an important need to understand retreatment options in those instances. This clinical trial was done to study the response to two different regimens, ledipasvir/sofosbuvir and ledipasvir/sofosbuvir with ribavirin, and to see if they are safe and well-tolerated in HCV-infected persons whose previous treatment with sofosbuvir had failed.
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
Hepatitis C is a global problem, prevalent in developed as well as in the developing countries. New treatment regimens using PegInterferon in combination with ribavirin has led to improved sustained viral response rates for some genotypes. A single arm, open labeled, multicentre trial was conducted to evaluate the response rate and safety of PegInterferon alfa-2a (Unipeg®) plus ribavirin (Ribazole®) for the treatment of patients with chronic hepatitis C infection. RVR at 4 weeks, ETR at 24 weeks for genotype 3 and at 48 weeks for genotype 1 patients and SVR was determined at 24 weeks after completion of treatment. Quality of life at baseline and at follow-up visits were determined using SF-36.
The PROP UP research study is funded by The Patient Centered Outcomes Research Institute (PCORI). PROP UP is a multi-centered prospective observational study that will evaluate all-oral treatment regimens for chronic hepatitis C viral (HCV) infection regarding several patient-reported outcomes (PROs) such as HCV-associated symptoms, treatment side effects, medication adherence, out of pocket costs, comorbid conditions, and long-term benefits of cure and harms of treatment to compare PROs of different treatment regimens, treatment durations, and patient subgroups. Participants will be recruited from 9 U.S. liver centers. Approximately 1920 patients with HCV infection who are prescribed a regimen containing Sofosbuvir/Ledipasvir(SOF/LED), SOF/Velpatasvir(SOF/VEL), Grazoprevir/Elbasvir(GRZ/ELB), OBV/PTV/r + DSV (PRoD), or daclatasvir/SOF (DAC/SOF) will be recruited and approximately 1600 patients who are approved and begin HCV treatment will be enrolled in the longitudinal study. PRO surveys will be evaluated before, during and after HCV treatment. PROP UP is a collaborative effort between behavioral and biomedical researchers, a patient engagement group and a patient advocacy organization.
This is a randomized, multi-site, open-label trial of the co-administration of a fixed-dose combination (FDC) of EBR 50 mg + GZR (100 mg) (EBR/GZR) and SOF 400 mg, with and without RBV, in treatment-naïve (TN) and treatment-experienced (TE) participants with chronic HCV GT3 infection with compensated cirrhosis.
The primary objective of this study is to evaluate the efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) for 12 weeks with or without ribavirin (RBV) in participants without cirrhosis, and LDV/SOF FDC for 12 weeks with RBV or LDV/SOF FDC for 24 weeks without RBV in participants with cirrhosis.
New and recently EMA/FDA approved direct acting antiviral (DAA) combination therapies cure 95% or more of the patients chronically infected with HCV genotype 1 and 4. Grazoprevir (MK-5172) and elbasvir (MK-8742) combination therapy is such a, albeit not yet EMA/FDA approved combination DAA therapy. It is likely that the synergistic effect of the host's immune response and antiviral therapy when given during the first 6 months of HCV infection makes antiviral therapy during acute HCV infection more effective. In this study the investigators would like to document that treatment of acute HCV with grazoprevir (MK-5172), elbasvir (MK-8742) is effective and can ben shortened from 12 to 8 weeks for HCV genotype 1 and 4 infection without substantial loss in efficacy. Study design and intervention: Prospective open label interventional clinical trial in which 80 acute HCV genotype 1 or 4 patients co-infected with HIV will receive 8 weeks of grazoprevir and elbasvir (a once-daily combination tablet). Study population: 80 Adult HIV positive patients with an acute HCV genotype 1 or 4 infection from 10 HIV treatment centers in the Netherlands and Belgium will be included. Primary endpoint: Sustained viral response (SVR) 12 weeks after the end of therapy in ITT study population (=genotype 1 and 4).
The CTSI-PLACE Study is a study for men and women with HIV/hepatitis C co-infection or HIV only. The study looks at the impact of having hepatitis C virus in addition to HIV on risk for cardiovascular disease. Participants will undergo non-invasive assessment of cardiovascular disease risk through measurements of endothelial function and blood biomarkers at baseline and 1 year (or 4 weeks and 24 weeks after end of HCV treatment for those that undergo HCV treatment during study follow-up).
The purpose of this study is to describe the genetic diversity of Hepatitis C virus (HCV) NS3/4a protease and NS5A protein of HCV in participants with chronic disease naive-drug or previously failed to double therapy (Peg-interferon and Ribavirin) and to identify the frequency of natural polymorphisms in HCV NS3/4a protease and NS5A protein that are associated with direct-acting antivirals (DAAs)-resistance.
