4-way Crossover QT Evaluation in Healthy Subjects
A Phase 1, Randomized, Blinded, Placebo and Moxifloxacin Controlled, 4-Period Crossover, Study Evaluating the Effect of ZTI-01 on 12-Lead Electrocardiogram Parameters in Healthy Adult Subject

Detailed Description
This is a single-center, randomized, placebo-controlled, four-period, cross-over study to assess the effect of single-doses of ZTI-01 at therapeutic (T) and supratherapeutic (ST) plasma concentrations on the QTc interval versus placebo (P) and an open-label moxifloxacin (M) control (400 mg PO).
Assessment of safety data will include changes from baseline in vital signs and laboratory parameters, infusion site reactions, adverse events and clinically significant changes from baseline in 12-lead ECG parameters.
