Filter by:This observational long-term follow-up study will assess the persistence of direct acting antiviral (DAA) resistant mutations and the durability of sustained virological response in patients with chronic hepatitis C who have participated in a Roche DAA treatment protocol. Up to 5 scheduled monitoring visits for blood sampling during an observational period of up to 36 months.
Hepatitis C is a small RNA virus spread by blood to blood contamination. There are to date 6 known genotypes and within each there are several subtypes. Although all genotypes are distributed worldwide some are more common in certain countries and/or among certain populations.
The purpose of this study is to evaluate the effect of 48 vs 24 weeks of treatment with Peginterferon alfa-2b plus weight-based ribavirin on Sustained Virologic Response (SVR) and relapse rates in patients infected with genotype 3 chronic hepatitis C (CHC) who do not achieve a Rapid Virologic Response (RVR) but attain a complete Early Virologic Response (cEVR).
The purpose of this study is to assess the safety and efficacy of combination treatment with VX-222 and telaprevir administered for 12 weeks with and without peginterferon-alfa-2a and/or ribavirin. The subjects enrolled in this study are chronically infected with hepatitis C virus (HCV) genotype 1 and will not have previously received treatment for their HCV infection. This study will include an Investigational Phase and Extension Phase. These phases will contain a Treatment Period and a Follow-up Period. All subjects will be enrolled in the Investigational Phase of this study. Subjects who fail treatment during the Investigational Phase will have the option to enter the Extension Phase at which point they will be eligible to receive peginterferon alfa-2a and ribavirin for a total of 48 weeks. Based on an evaluation of on-treatment safety, pharmacokinetic and antiviral data from patients in each arm of the trial, Vertex may elect to enroll up to two additional treatment arms (Treatment Arm E and Treatment Arm F) that will evaluate telaprevir/VX-222-based combination therapy. The components of the treatment regimens of these arms will be selected based on clinical data that emerges from the four initially-studied regimens. If enacted, up to 25 patients are expected to enroll in each additional treatment arm. If Treatment Arm E or Treatment Arm F is discontinued subjects meeting certain criteria will have the option to enter a telaprevir-containing Rollover Phase. Subjects who do not meet the eligibility criteria to enter the Rollover Phase may elect to enter the Extension Phase.
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.
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.
