This is a Phase 1, single-center, open-label, three subsequent dosing periods study to evaluate the drug-drug-interaction (DDI), pharmaco-kinetics (PK) and pharmacodynamics (PD), safety, and tolerability of a single dose of EYP100a combined with ETV in healthy men and women dosed in the morning under fasted conditions.
NCT01879462
GSK2878175 is a site IV NS5B non-nucleoside inhibitor (NNI) being developed for the treatment of chronic HCV infection. This study represents the first administration of GSK2878175 in humans to define safety, tolerability, and pharmacokinetics (PK) following single and repeat doses of GSK2878175 in healthy subjects. This is a Phase 1, randomized, single-blind, placebo-controlled, dose escalation study to determine the safety, tolerability, and PK profile of GSK2878175 in single (Part 1) and repeat doses (Part 2) in healthy subjects. In addition the study will explore the effect of a moderate (30%) fat meal on single dose PK endpoints in healthy subjects.

NCT03524014
The present research aims to collect virological and clinical data on hepatitis E virus (HEV) infections, either in acute or chronic forms of HEV infection in North-Eastern France, with liver- or non liver-related symptoms, plus data on HEV circulation in the outside environment. The purpose of this study is to improve the diagnosis and care of HEV-infected patients, as well as the preventive features to take into account in order to avoid food- and environment-borne infections. At last, we will investigate HEV molecular characteristics, with the hypothesis that some advantageous HEV strains coul be more pathogenic for some tissues and/or organs.

NCT00998985
This multiple dose study will assess the safety, tolerability, pharmacokinetics and pharmacodynamics of grazoprevir (MK-5172) in Genotype (GT) 1 and GT3 Hepatitis C virus (HCV)- infected participants. The primary hypothesis is that administration of grazoprevir for 7 days is sufficiently safe and well tolerated in HCV-infected males.
NCT01532973
The purpose of this study is to assess the safety, pharmacokinetics (PK) and pharmacodynamics of elbasvir (MK-8742) in Hepatitis C Virus (HCV)-infected participants. There will be 3 parts to this study; Part I will enroll only genotype (GT) 1 HCV-infected participants, Part II will enroll GT3 HCV-infected participants, and Part III will enroll only GT1a HCV-infected participants. All parts may run concurrently, or Parts II and III may be staggered. Hypothesis (Part I): At a once-daily dose that is sufficiently safe and well tolerated in HCV-infected participants, elbasvir administered for 5 consecutive days has superior antiviral activity in GT1 HCV-infected participants compared to placebo, as measured by change from baseline in plasma HCV ribonucleic acid (RNA; log 10 copies/mL) at Day 5, 24-hour postdose timepoint. (a true mean viral RNA reduction of at least 3 log10 is anticipated). Hypothesis (Part II): At a dose that is sufficiently safe in GT3 HCV-infected participants, the mean maximum reduction in HCV viral load is greater following multiple dose oral administration of elbasvir as compared to placebo. Hypothesis (Part III): At a once-daily dose that is sufficiently safe and well tolerated in HCV-infected participants, elbasvir administered for 5 consecutive days has superior antiviral activity in GT1a HCV-infected participants compared to placebo, as measured by change from baseline in plasma HCV RNA (log 10 copies/mL) at Day 5, 24-hour postdose timepoint. (a true mean viral RNA reduction of at least 3 log10 is anticipated).
NCT01889433

NCT01945294
The purpose of this study is to estimate the difference in the efficacy between a 16-week treatment regimen of boceprevir (BOC) in combination with peg-intron alpha 2b (P) plus ribavirin (R) (BOC + PR) and a 28-week treatment regimen of BOC + PR in previously untreated participants with chronic hepatitis C (CHC) genotype 1 in Asia who achieve undetectable hepatitis C virus ribonucleic acid (HCV RNA).
NCT00136214
The hypothesis of this study is that pegylated interferon would cause cognitive deficits and mood changes in hepatitis C (HCV) positive subjects.
NCT01205165
Objective(s) The primary study objective is to assess the antiviral effect of 12 weeks of adefovir dipivoxil treatment in Korean patients with chronic hepatitis B and compensated liver disease. The secondary study objectives are to assess the antiviral effect, clinical benefit and safety of 52 weeks of adefovir dipivoxil treatment. Endpoint(s) The primary efficacy endpoint is "Mean log10 reduction in serum HBV DNA level from baseline to Week 12". The secondary efficacy endpoints include (a) the proportion of patients achieving serum ALT normalization at Week 52, (b) other assessments of antiviral effects (the proportion of patients achieving HBV DNA no less than 300 copies per mL at Week 52), (c)HBeAg loss, HBeAg seroconversion, HBsAg loss and HBsAg seroconversion, (d)the proportion of patients achieving serum ALT normalization at Week 12. Study Design This is an open label, multi centre phase IV study for Korean patients with chronic hepatitis B and compensated liver disease, assessing the antiviral effect of 12 weeks treatment of Adefovir dipivoxil as a primary objective and antiviral effect, clinical benefit and safety of 52 weeks treatment as secondary objectives. Patients will be screened for eligibility criteria and the baseline visit for the treatment initiation should occur no more than 4 weeks after screening. Total treatment period will be 52 weeks and patients will return to the clinic for assessments as scheduled during treatment period. After the 52 week study period, it is likely that the patient will benefit from continued treatment with commercial adefovir. If in the investigator's clinical judgement this is the case, the investigator should ensure that a routine prescription is available in a timely manner, and that no unnecessary interruption in treatment occurs. Study Population A minimum of 100 male or female Korean patients more than 18 years of age with HBeAg positive chronic hepatitis B and compensated liver disease who meet the eligibility criteria will be enrolled. Study Assessments and Procedures Potential patients will be screened prior to study entry and eligible patients who have given their consent will have further baseline assessments. Following the screening, the first doses of study medications will be given at baseline and patients will return to the clinic for assessment as scheduled during treatment period. Patients who discontinue treatment prematurely will be followed up every 4 weeks for 12 weeks following the withdrawal visit. The following key assessment and or measurement will be made at one or more visits during the study. (See section 14.1 Appendix 1. Time and event schedule): * Pregnancy test (females of child-bearing potential only) * Haematology and serum chemistry profile including prothrombin time(PT) and AFP * HBV DNA (Roche COBAS AMPLICOR HBV MONITOR Test, LLOD 300 copies per ml) * Hepatitis B markers: HBeAg(Anti HBe will be tested if HBeAg is negative), HBsAg(Anti HBs will be tested if HBsAg is negative) Investigational Product(s) Adefovir dipivoxil 10mg tablets will be supplied by GlaxoSmithKline and presented as a white to off white, round tablets, packaged in the bottle containing 30 tablets
