Trial overview

Official title: Double-Blind, Randomized, Placebo-Controlled Study to Assess Safety, Efficacy, and Pharmacokinetics (PK) of GSK2336805 in Combination With Peginterferon and Ribavirin in Treatment-naive Chronic Hepatitis C Subjects With Hepatitis C Virus Genotypes 1 or 4
Trial description: 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).
