Change in HCV RNA Levels of MP-424
Date were collected at Day -28, Day1 (0 (pre-dose), 2.5, 4, 8, 16 hours post-dose), Day2, Day3, Day8, Day14, Day29, Day43, Day57, Day86. Change Value was calculated as the each time point minus the baseline point which was averaged Day -28 and Day0-0hour(pre-dose)).
Time frame: Day1 (2.5, 4, 8, 16 hours), Day2, Day3, Day8, Day14, Day29, Day43, Day57 and Day86
