  Purpose

The purpose of this study is to assess the affect that PF-00232798 has on QT interval. A prolonged QT interval is a risk factor for arrhythmias.

Primary Outcome Measures:
  • QTc, using Fridericia's correction method (QTcF) at each time point of PF-00232798 and placebo on Day 7. [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • QTcF, or any other appropriate correction method at each postdose time point of moxifloxacin on Day 7 [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
  • QTcB or any other appropriate correction method at each postdose time point of PF-00232798 and placebo on Day 7 [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
  • Pharmacokinetic endpoints for PF-00232798 (Tmax, Cmax, Cτ, and AUClast) [ Time Frame: 7 days ] [ Designated as safety issue: No ]
  • Safety and toleration assessed by spontaneous reporting of adverse events, vital signs, 12-lead ECG and laboratory safety assessments [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
