Arm Intervention/treatment
Experimental: Talampanel Drug: Talampanel
titrated to 50mg three times a day over 9 days and a single dose administered on Day 10
Other Name: TV-7600, GYKI 53773

Placebo Comparator: Placebo Drug: Placebo
administered three times a day over 9 days and a single dose administered on Day 10

Moxifloxacin Drug: Moxifloxacin
Placebo administered three times a day over 9 days and a single dose of moxifloxacin administered on Day 10
Other Name: Avelox

Primary Outcome Measures :
  1. To determine the effects of Talampanel on cardiac repolarization after multiple therapeutic doses administered over 10 days [ Time Frame: 12 days ]

Secondary Outcome Measures :
  1. Examine the PK profile of talampanel and its metabolite -Assess the PK/PD relationship of the time course of QT/QTc interval prolongation-Assess the safety and tolerability of multiple doses of talampanel in healthy volunteers [ Time Frame: 12 days ]
