NCT01457768
This Registry is designed to obtain long term data on participants who have failed to achieve sustained virologic response (SVR) while receiving at least one Gilead oral antiviral agent (OAV) in a previous Gilead-sponsored hepatitis C virus (HCV) study.
NCT02128217
Early identification of acute HCV infection is essential to prevent chronic infections and the long-term liver disease complications that may occur. Early identification and treatment of HCV during the acute phase can result in significantly higher response rates with shorter durations of therapy. Pegylated-interferon alfa (PEG-IFN) was the typical treatment for HCV infection. Participants subcutaneously inject PEG-IFN where the average duration of treatment was approximately 20 weeks. With the advancement of direct-acting antivirals (DAAs), it was possible to see if a new DAA might be non-inferior compared to (PEG-IFN). The study was designed to see if a fixed-dose combination tablet can replace the old HCV treatments by being more effective, safer and better tolerated in HIV-infected participants with new HCV infection. The study was a Phase I, open-label, two cohort clinical trial, in which 44 acutely HCV-infected HIV-1 positive participants were enrolled. Participants in each cohort were evaluated in two steps: on treatment (Step 1) and follow-up after discontinuing study treatment (Step 2). The cohorts were enrolled sequentially. Participants in Cohort 1 were enrolled and administered oral Sofosbuvir (SOF) in combination with weight-based ribavirin (RBV). Participants in Cohort 2 were enrolled and administered an oral fixed dose combination of Ledipasvir/Sofosbuvir (LDV/SOF).
NCT02465203

NCT01439373
GSK2336805 is a hepatitis C virus (HCV) NS5A inhibitor being developed for the treatment of chronic hepatitis C (CHC). This study will assess the safety, antiviral activity, and pharmacokinetics of GSK2336805 alone and in combination with peginterferon alfa 2a and ribavirin in subjects with chronic hepatitis C (CHC).
NCT01648140
GSK2336805 is a novel hepatitis C virus (HCV) non-structural 5A (NS5A) inhibitor being developed for the treatment of chronic HCV infection. This Phase II, multicenter, parallel-group, randomized, dose-ranging study will assess the safety and tolerability, antiviral activity, and pharmacokinetics of GSK2336805 at 2 dose levels (40 and 60 mg) in combination with pegylated interferon alfa-2a (PEG) and ribavirin (RIBA) in approximately 100 treatment-naïve subjects with chronic genotype 1 HCV infection. In a separate nonrandomized single-arm cohort, up to 15 treatment-naïve subjects with genotype 4 chronic HCV infection will be enrolled in parallel at the dose level of 60 mg of GSK2336805.
NCT01590615
This registry will remain open for approximately 5 years (4 years of enrollment + 1 year of follow up). Subjects will be followed until Orthotopic Liver Transplant (OLT), resolution of liver decompensation, death, or conclusion of the registry.
NCT00197015
This is a study to evaluate the immune response and safety of GSK Biologicals 2-dose inactivated hepatitis A vaccine when administered with a measles/mumps/rubella vaccine and a varicella (chickenpox) vaccine in children as young as 15 months of age. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
NCT02673489
The purpose of this study is to determine whether 24 weeks of Daclatasvir and Sofosbuvir with Ribavirin is safe and effective in the treatment of genotype 3 hepatitis C infected patients with liver cirrhosis.
NCT00087633
This 2-arm study was designed to evaluate the efficacy, safety, and tolerability of prophylactic PEGASYS plus COPEGUS after liver transplantation for hepatitis C, compared to initiation of antiviral therapy at the time of clinical recurrence of hepatitis C infection. The anticipated time on study treatment was 3-12 months, and the target sample size was 100-500 individuals.
NCT00512278
The aim of the study is to investigate in subjects receiving their first course of peg-interferon α-2b plus ribavirin therapy for chronic HCV infection
NCT01265511
This study will examine the effectiveness of 28 days of triple combination therapy including SCY-635 with peginterferon alfa 2a and ribavirin in reducing serum HCV RNA levels. An additional 20 weeks of treatment with the currently approved standard of care will be offered to all participants. The Week 24 visit will be the last on-study visit. After the Week 24 visit, all subjects with undetectable HCV RNA will be given the option to continue treatment with standard of care for an additional 24 weeks (out to Week 48) under the care of their Principal Investigator.
NCT01349465
The purpose of this study is to investigate durability of SVR in chronic HCV patients who achieved SVR in the previous study with TMC435-containing regimen and time for resistance associated mutations to return to baseline in chronic HCV patients who did not achieve SVR in the previous study with TMC435-containing regimen.
NCT00277238
The purpose of this study is to determine the efficacy and tolerability of CPG 10101 at two different dose levels with pegylated-interferon-alpha 2B (PEG-IFN) plus ribavirin (RBV) compared to PEG-IFN and RBV without CPG 10101 in HCV positive subjects who were classified as non-responders to previous adequate PEG-IFN plus RBV therapy.
NCT01482390
This randomized, double-blind, multi-center, parallel-group study will evaluate the sustained virologic response and the safety of mericitabine (RO5024048) (MCB) in combination with telaprevir (TVR) and peginterferon Alfa-2a (PEG-IFN) / ribavirin (RBV) in participants with chronic Hepatitis C infection.
NCT00106964
Hepatitis B is a contagious virus that can damage a person's liver. It can be prevented by vaccination, but for many HIV-positive people, the vaccines do not help them achieve adequate protection against this virus. In an attempt to improve response to vaccination and achieve protection from hepatitis B, this trial will compare the immune system response to 3 hepatitis B vaccine regimens in HIV-positive adolescents 12 through 24 years of age.
NCT01332552
GSK2485852 is a Hepatitis C NS5B site IV non-nucleoside polymerase inhibitor being developed for the treatment of chronic HCV infection. HBI115040 is the first administration of GSK2485852 in humans to establish the initial safety, tolerability, pharmacokinetic, and antiviral profile. The study design is a fusion of single and repeat dosing cohorts in HCV infected subjects to evaluate the safety, pharmacokinetics, and antiviral activity of GSK2485852. HBI115040 describes a Phase I, randomized, double-blind, placebo-controlled, dose escalation fusion study to determine the safety, tolerability, pharmacokinetic, and antiviral profile of GSK2485852 in single doses (Part 1), repeat doses (Part 2), and ritonavir co-administration (Part 3) in chronically infected HCV subjects. The study will also explore the effect of a moderate (30%) fat meal on pharmacokinetic endpoints in HCV subjects in Part 1.
NCT01827657
This is a single-dose, open-label, two part, parallel group study. This study is being conducted to determine the pharmacokinetics, safety and tolerability of GSK2336805 in subjects with varying degrees of hepatic impairment. Part 1 of the study will enroll subjects with mild and moderate hepatic impairment and healthy control subjects matched to the subjects in the moderate hepatic impairment category. The decision to commence Part 2 will be based on a review of the preliminary safety and pharmacokinetic data from subjects with moderate hepatic impairment. Part 2 will enroll subjects with severe hepatic impairment. Additionally, based on emergent data from Part 1, matched controls to the severe hepatic group may be enrolled (optional). Due to the potential difficulty in identifying eligible subjects with severe hepatic impairment, the study may be stopped prior to full enrollment in Part 2, provided that a minimum of 4 evaluable subjects with severe hepatic impairment have been enrolled. The study will consist of a Screening visit, a single dose Treatment Period and a Follow-up visit. Subjects will be screened for eligibility criteria within 30 days of enrolment. Subjects will be admitted to the clinical unit on Day -1; each subject will receive a single dose of GSK2336805 on Day 1 and will remain in the clinical unit for 5 days (check-out on Day 4). The follow-up visit will be conducted within 7-10 days after Day 1 dosing.
NCT00142740
