What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in the mean time-matched QTcI (QT interval, individually corrected according to the factor estimated from each subject) |  | Baseline (day -1) and 20 to 120 min. after drug administration | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of the QTcI at different point |  | Baseline (day -1) and 10 min. to 8 hours after drug administration | 
| The mean of the QTcI values of all ECGs for Moxifloxacin and Placebo |  | 1 to 4 hours after drug administration |
