BACKGROUND Interferon-free regimens are needed to treat hepatitis C virus (HCV) infections. We investigated the efficacy of combined simeprevir and sofosbuvir. METHODS We enrolled patients with chronic HCV genotype 1 infections who had previously not responded to pegylated interferon (peginterferon) and ribavirin or were treatment naive. Patients were(More)
BACKGROUND Although the addition of the HCV NS3/4A protease inhibitors boceprevir and telaprevir to pegylated interferon (peginterferon) alfa plus ribavirin has improved sustained virological response (SVR) in treatment-naive and treatment-experienced patients infected with hepatitis C virus (HCV) genotype 1, the regimens have a high pill burden and are(More)
BACKGROUND & AIMS Simeprevir (SMV) is a once-daily (QD), oral hepatitis C virus (HCV) NS3/4A protease inhibitor approved for treatment of genotype (GT) 1 and GT4 infection. This Phase III, open-label, single-arm study (RESTORE; NCT01567735) evaluated efficacy/safety of SMV with peginterferon-α-2a/ribavirin (PR) in patients with chronic HCV GT4 infection. (More)
BACKGROUND Pegylated interferon (peginterferon) alfa 2a or 2b plus ribavirin regimens were the standard of care in patients with hepatitis C virus (HCV) infection, but the sustained virological response can be suboptimum in patients with HCV genotype 1 infection. The efficacy, safety, and tolerability of the combination of simeprevir, a one-pill,(More)
BACKGROUND & AIMS Simeprevir is an oral, once-daily inhibitor of hepatitis c virus (HCV) protease NS3/4A. We investigated the safety and efficacy of simeprevir with peg-interferon α-2a and ribavirin (PR) in a randomized, double-blind, placebo-controlled, phase 3 trial of patients with HCV genotype 1 infection who relapsed after previous interferon-based(More)
Simeprevir, a hepatitis C virus (HCV) NS3/4A protease inhibitor, displays nonlinear pharmacokinetics (PK) at therapeutic doses. Using physiologically based PK modeling, various drug-drug interactions were simulated with simeprevir as victim drug to identify whether saturation of the predominant metabolic enzyme (CYP3A4) or the active hepatic transporters(More)
In this multicenter, double-blind, placebo-controlled, randomized, four way cross-over proof-of-mechanism study, we tested the effect of the positive allosteric α7 nicotinic acetylcholine receptor (nAChR) modulator JNJ-39393406 in a key translational assay (sensory P50 gating) in 39 regularly smoking male patients with schizophrenia. All patients were(More)
BACKGROUND Simeprevir is an oral, once-daily, hepatitis C virus (HCV) NS3/4A protease inhibitor for the treatment of chronic HCV genotype 1 infection. Human immunodeficiency virus (HIV) coinfection accelerates progression of liver disease. This uncontrolled, open-label trial explored the safety and efficacy of simeprevir in patients with HCV genotype 1/HIV(More)
BACKGROUND We did a phase 3 study in previous non-responders with chronic hepatitis C virus (HCV) genotype 1 infection and compensated liver disease that related to the standard of care for these patients at the time this study was initiated. We investigated whether simeprevir is non-inferior in terms of efficacy to telaprevir, each in combination with(More)
This pooled analysis of five Phase IIb and III studies evaluated the safety and tolerability of simeprevir, a once daily, oral hepatitis C virus (HCV) NS3/4A protease inhibitor. Data were summarised for patients who received simeprevir 150 mg once daily (n = 924) or placebo (n = 540) plus pegylated interferon-α/ribavirin for 12 weeks. During the first 12(More)
