  Purpose

The purpose of this study was to determine the safety, tolerability and pharmacokinetics of sequential ascending doses of JTK-853 administered for 14 days in healthy subjects and also to determine the effect of a single dose of ketoconazole on the steady-state pharmacokinetic profile of JTK-853 and its metabolite M2 (one cohort only).

Primary Outcome Measures:
  • Number of subjects with adverse events [ Time Frame: 3 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Maximum concentration (Cmax) of JTK-853 and metabolite M2 [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • Time to reach peak or maximum concentration (tmax) for JTK-853 and metabolite M2 [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • Area under the concentration-time curve during the dosing interval (AUCtau) for JTK-853 and metabolite M2 [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • Elimination half-life associated with the terminal slope (λz) of a semilogarithmic concentration-time curve (t1/2) for JTK-853 and metabolite M2 [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • Maximum concentration (Cmax) of JTK-853 and metabolite M2 after Ketoconazole administration [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • Area under the concentration-time curve during the dosing interval (AUCtau) for JTK-853 and metabolite M2 after ketoconazole administration [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
