This is a Phase I, single-center, double-blinded, randomized, placebo-controlled, five-period cross-over clinical study of PA-824 to evaluate the effect of PA-824 and of PA-824 plus moxifloxacin on cardiac repolarization (QT/QTc interval duration) in healthy male and female participants. Moxifloxacin will be used as an active control. Participants will be blinded to the treatments they will receive. The study consists of a screening period up to 26 days; enrollment, 1 day; five in-patient treatment periods consisting of an admission day (except in the first treatment period, when the pre-dose day is the baseline), dosing day and two post-dosing days; an out-patient period of at least three days and not more than 10 days between treatment periods; and a final visit 7 - 14 days after discharge from the last treatment period. During the study, the subjects will receive each one of the following five treatments: Treatment A: PA-824 placebo and moxifloxacin placebo; Treatment B: PA-824 400 mg plus moxifloxacin placebo; Treatment C: PA-824 1000 mg plus moxifloxacin placebo; Treatment D: PA-824 placebo plus moxifloxacin 400 mg; Treatment E: PA-824 400 mg plus moxifloxacin 400 mg. The primary objective is to evaluate the effect of single-dose administration of PA-824 400 mg and 1000 mg versus placebo on the QTcI interval. A total of 75 randomized (in order to have at least 60 evaluable) healthy male and female volunteers, aged 18 to 45 years will be enrolled.
