Filter by:The aim of this randomized clinical study is to show non-inferiority of a change of anti-viral therapy from telbivudine to lamivudine in patients who have achieved an undetectable viral load at week 24 of telbivudine therapy compared to continuous treatment with telbivudine with respect to the viral breakthrough rate at week 108 as the primary clinical outcome.
Hepatitis C virus (HCV) infection, a leading cause of cirrhosis, hepatocellular carcinoma (HCC) and liver transplantation, affects approximately 170 million individuals worldwide. The prevention of HCV transmission and early intervention of HCV infection are urgently needed to reduce or halt the liver-related morbidity and mortality. Double filtration plasmapheresis (DFPP) has been with widespread use in clinical practice for several indications with plasma filters optimized for the respective elimination targets with excellent safety. By way of the plasma separator, the blood is separated into plasma and cell components. Separated plasma is then led into the plasma component separator where the pores of the plasma component separator further fractionate the plasma into large and small molecular components. The large molecular components, including pathogenic substances, is removed and discarded and the small molecular components, including proteins such as albumin and gamma-globulin, are returned to the patient and mixed with the cell components. After the initiation of pegylated interferon plus ribavirin (Peg-IFN+RBV) therapy, the rapid first phase relates to a significant reduction in virus production and the degradation of free virus particles, which is followed by a second much slower one reflecting the elimination and clearance of infected cells. In HCV patients, high baseline viral load at the initiation of therapy is considered to be a negative predictor for systemic vascular resistance (SVR) for HCV genotype 1 patients. Reduction of baseline viral load by means of therapeutic double filtration plasmapheresis (DFPP) may represent a plausible adjunct for improved antiviral therapy to reduce the virus load with the initiation of treatment in synergy with Peg-IFN and RBV combination therapy. Recently, several clinical studies in evaluating the therapeutic efficacy and safety of DFPP in conjunction with IFN-based therapy were conducted for treatment-naïve genotype 1 high viral load CHC patients, and CHC patients who underwent liver transplantation. These studies showed that patients with DFPP treatment had more favorable HCV early viral kinetics to those without DFPP treatment. Furthermore, all these studies showed excellent safety after DFPP treatment. Therefore, the investigators aimed to conduct a large-scaled randomized controlled trial to evaluate the overall response of DFPP for HCV genotype 1 patients with high viral load.
This study will assess the efficacy of ABF656 in chronic hepatitis B characterized by HBeAg positivity. The study is designed to establish a dose response and safety relationship sufficient to allow the subsequent design and conduct of Phase 3 trials. The trial is also designed to generate the PK data in hepatitis B patients to satisfy regulatory requirements in China.
This study aims to evaluate whether an investigational monoclonal antibody, CT-011, is safe to give and if it helps patients with hepatitis C virus (HCV). Monoclonal antibodies are a type of drug that is typically given by infusion into a vein (intravenously). Results of this trial will help doctors obtain additional information with regard to the safety and efficacy of CT-011 as a potential treatment for HCV.
This study will evaluate the hepatic (liver) and plasma pharmacokinetics of Vaniprevir (MK-7009) by evaluation of ribonucleic acid (RNA) of the hepatitis C virus (HCV) in genotype 1, HCV-infected participants.
The purpose of this study is to test whether the correction of insulin resistance with pioglitazone, will improve the response to antiviral treatment.
This is a non-randomized, open-label study examining the safety and efficacy of betaine in addition to standard anti-viral therapy in genotype 1 hepatitis C non-responders or relapsers to previous pegylated interferon plus ribavirin. Betaine (20 gm/day) in 2 divided doses will be added to Peginterferon alpha 2a (180 mcg) plus weight-based Ribavirin (1000 or 1200 mg/day, for body weight < or > 75 kg, respectively, for 48 weeks. Patients must be diagnosed with chronic hepatitis C, genotype I, and have undergone therapy for hepatitis C with pegylated interferon plus ribavirin. Subjects will be followed for safety, tolerability, hepatitis C viral response and the effect on interferon gene signaling in peripheral blood mononuclear cells during therapy.
The purpose of this study is to determine whether obese people do not respond to hepatitis C treatment as well as lean people. This research studies whether obese people will show higher sustained virologic response rate if they lose weight by Orlistat use and dietary and lifestyle modification.
The purpose of the study is to look at cells of the immune system to see if the cells are different among people with different risk factors that have received a liver transplant. We will enroll 50 patients receiving liver transplant and their donors. Both donor and recipient must participate in the order for the recipient to participate in the study. We will take blood samples from these patients and their donors.
This is a Phase 4, retrospective and observational, multicenter, national (Brazil), open, noncomparative, and nonrandomized study, which does not have visits. This study will be conducted in accordance to Good Clinical Practices. The procedure will be the review of medical records of patients who have already completed 12 weeks of treatment of chronic hepatitis C with peginterferon alfa-2b and ribavirin. This review will take place after the subjects have signed the informed consent form authorizing collection of these data. The collection of data for virological response after Week 12 will be collected prospectively through the review of medical records after the subjects have completed their entire treatment and follow-up period.
