Safety and Efficacy of Vaniprevir (MK7009) Administered With Pegylated-Interferon and Ribavirin (MK-7009-007)

10. september 2018 opdateret af: Merck Sharp & Dohme LLC

A Phase II, Randomized, Placebo-Controlled Study to Evaluate the Safety and Efficacy of MK7009 Administered Concomitantly With Pegylated-Interferon and Ribavirin for 28 Days in Treatment-Naive Patients With Chronic Hepatitis C Infection

A study to evaluate how effective different levels of Vaniprevir (MK-7009), when administered with Pegylated-Interferon (Peg-IFN) and Ribavirin, are at achieving rapid viral response (RVR) i.e., undetectable hepatitis C virus [HCV] viral ribonucleic acid [RNA] at Week 4 in participants with chronic HCV infection. The primary hypothesis was that the proportion of participants in one or more of the Vaniprevir treatment groups achieving RVR would be greater than the proportion of placebo participants achieving RVR when Vaniprevir and placebo were co-administered with Peg-IFN/Ribavirin.
