Filter by:This is an open-label trial to evaluate safety and efficacy of treatment with BEM + RZR in subjects with chronic HCV infection.
The purpose of this study is to determinate the AMH levels before and after antiviral therapy with Ombitasvir-Paritaprevir-Ritonavir and Dasabuvir in comparison with age-matched HCV-positive women not undergoing antiviral treatment.
The main objective of this study is to evaluate the safety and effectiveness of paritaprevir/ritonavir/ombitasvir with ribavirin used for participants infected with chronic hepatitis C virus (HCV) genotype 2 in daily practice in Japan.
The purpose of this multicenter, single-arm, combination-drug study, which includes 12 weeks of treatment and 24 weeks of follow-up, is to evaluate the safety, efficacy and pharmacokinetics of ombitasvir/paritaprevir/ritonavir in Japanese adults infected with HCV GT1b, who are treatment-naïve or treatment-experienced to an IFN-based regimen and who have ESRD on HD.
The purpose of this phase 3 study is to evaluate the efficacy and safety of ABT-493/ABT-530 in comparison to sofosbuvir plus ribavirin for 12 weeks in Hepatitis C Virus (HCV) Genotype 2 (GT2) infected participants.
The purpose of this phase 3, multicenter study is to evaluate the efficacy and safety of ABT-493/ABT-530 in Japanese adults with chronic Hepatitis C Virus (HCV)-infected, HCV direct-acting antiviral agent (DAA) treatment-naïve, and DAA treatment-experienced Japanese adult subjects.
The main objective of this study is to evaluate the safety and effectiveness of paritaprevir/ritonavir/ombitasvir used for patients infected with HCV genotype 1 in daily practice in Japan.
This was an efficacy and safety study of grazoprevir (MK-5172) in combination with elbasvir (MK-8742) in treatment-naive participants with chronic hepatitis C virus (HCV) genotype (GT) 1, 4, or 6 infection. Participants were randomly assigned (3:1 ratio) to immediate treatment or deferred treatment (placebo control). The primary efficacy hypothesis was that the proportion of participants receiving combination therapy in the Immediate Treatment Arm who achieve sustained viral response at 12 weeks after the end of study treatment (SVR12) is superior to 73%.
Chronic hepatitis C virus (HCV) infection and nonalcoholic fatty liver disease (NAFLD) are characterized by a spectrum of pathological conditions ranging from an early stage of inflammation and fibrosis up to more advanced disease conditions, such as hepatocellular carcinoma. The prevalence of NAFLD is between 10 and 25% of the population, with large differences in age and ethnic groups, while it is well known that HCV infection is a major cause of chronic liver disease in Western countries. For both diseases the progression of liver damage is in close correlation with the lifestyle of patients (eg., nutrition, physical activity, ingestion of alcohol, etc.). In fact, it was shown that feeding imbalances may have implications in altering the normal immune functions of the subjects, suggesting that the metabolic and the immune systems are closely related to each other. Although it is well known the negative role of obesity on the progression of NAFLD and HCV liver diseases, the pathogenic mechanism underlying the alterations related to the immune response is not yet fully understood. Insulin resistance, altered lipid metabolism, lipid peroxidation, oxidative stress and mitochondrial alterations are pathogenic mechanisms that induce liver damage and its progression, both in NAFLD and in HCV infection. Recent studies suggest that the evolution of viral infections and chronic inflammation in NAFLD are deeply influenced by CD4+ T helper cells expressing IL-17 , defined as T helper 17 (Th17) cells. Broadening the knowledge on the role of diet in the course of NAFLD and HCV infection in the activation of Th17 cells and in the alteration of some of their functions, will allow to shed light on the pathogenic mechanisms underlying the progression of immune-mediated diseases. Moreover, this investigation will allow to understand whether Th17 cells may have a role in the diminished response to therapy in patients who have high cholesterol levels. If the results will confirm our hypothesis, this study will provide useful informations for the clinical management of patients with both steatosis and chronic HCV infection. The data obtained can also be used for the development of new therapeutic strategies directed to modulate the antiviral immune response. All patients will undergo clinical and instrumental assessment depending on the type of pathology. Patients will be required to follow a normocaloric low cholesterol diet for a period of 30 days. The prospective clinical study does not present any form of additional risk for the patients and will be conducted in accordance with the principles established by the Declaration of Helsinki and with the standards of Good Clinical Practice (GCP). The study does not require any additional costs.
Parts A and B of this study are designed to evaluate the safety, tolerability, efficacy and pharmacokinetic profiles of samatasvir and simeprevir when administered in combination with ribavirin (RBV) for 12 weeks in treatment-naïve, Genotype (GT) 1b, 4 and 6 hepatitic C virus (HCV)-infected participants. Part C of this study is designed to evaluate the safety, tolerability, efficacy and pharmacokinetic profiles of samatasvir, simeprevir, TMC647055 and ritonavir (RTV) when administered in combination with or without RBV for 12 weeks in treatment-naïve or interferon/RBV-treatment relapsed, GT 1a and 1b HCV-infected participants.
