Primary Outcome Measures:
  • Cmax (Maximum Observed Concentration in Plasma) of MP-424 [ Time Frame: Date were collected at Day1 to Day85 ] [ Designated as safety issue: No ]
    Date were collected at Day1 (0 (pre-dose), 1 ,2.5, 4, 6, 8, 12, 16 hours post-dose), Day14 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16 hours post-dose) and Day85 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16, 24 hours post-dose). Date as pre-dose were collected at Day2, Day3, Day8, Day15, Day29, Day43 and Day57.

  • Tmax (Time of Maximum Plasma Concentration) of MP-424 [ Time Frame: Date were collected at Day1 to Day85 ] [ Designated as safety issue: No ]
    Date were collected at Day1 (0 (pre-dose), 1 ,2.5, 4, 6, 8, 12, 16 hours post-dose), Day14 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16 hours post-dose) and Day85 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16, 24 hours post-dose). Date as pre-dose were collected at Day2, Day3, Day8, Day15, Day29, Day43 and Day57.

  • AUC 0-8h (Area Under the Concentration-time Curve From Time Zero to 8 Hours) of MP-424 [ Time Frame: Date were collected at Day1 to Day85 ] [ Designated as safety issue: No ]
    Date were collected at Day1 (0 (pre-dose), 1 ,2.5, 4, 6, 8, 12, 16 hours post-dose), Day14 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16 hours post-dose) and Day85 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16, 24 hours post-dose). Date as pre-dose were collected at Day2, Day3, Day8, Day15, Day29, Day43 and Day57.

  • Ctrough (Plasma Trough Concentration) of MP-424 [ Time Frame: Date were collected at Day1 to Day85 ] [ Designated as safety issue: No ]
    Date were collected at Day1 (0 (pre-dose), 1 ,2.5, 4, 6, 8, 12, 16 hours post-dose), Day14 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16 hours post-dose) and Day85 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16, 24 hours post-dose). Date as pre-dose were collected at Day2, Day3, Day8, Day15, Day29, Day43 and Day57.

  • t1/2 (Half Life Period) of MP-424 [ Time Frame: Date were collected at Day1 to Day85 ] [ Designated as safety issue: No ]
    Date were collected at Day1 (0 (pre-dose), 1 ,2.5, 4, 6, 8, 12, 16 hours post-dose), Day14 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16 hours post-dose) and Day85 (0 (pre-dose), 1, 2.5, 4, 6, 8, 12, 16, 24 hours post-dose). Date as pre-dose were collected at Day2, Day3, Day8, Day15, Day29, Day43 and Day57.


Secondary Outcome Measures:
  • Change in HCV RNA Levels of MP-424 [ Time Frame: Day1 (2.5, 4, 8, 16 hours), Day2, Day3, Day8, Day14, Day29, Day43, Day57 and Day86 ] [ Designated as safety issue: No ]

    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)).
