Title: A Randomized, Double Blind, Dose Escalation, Fusion, First Time in Human Study to Assess the Safety, Tolerability, Pharmacokinetics, and Antiviral Activity of Single and Repeat Doses of GSK2336805 in Healthy Volunteers and Single Doses in Chronically Infected Hepatitis C Subjects
Brief Summary: This study is a three Part, Phase 1, randomized, dose-escalation, fusion, placebo-controlled, double-blind study to determine the safety, tolerability and Pharmacokinetic (PK) profile of GSK2336805 in healthy subjects and the safety, tolerability, PK, and antiviral profile of GSK2336805 in subjects chronically infected with HCV: i. Single doses in healthy subjects and the effect of food on GSK2336805 PK (Part 1). ii. Repeat doses in healthy subjects (Part 2) iii. Single doses in chronically infected HCV positive subjects (Part 3).
