A Single-centre, Randomised, Double-blind, Placebo Controlled Phase I Study in Two Parts: Part A to Assess a Safe and Tolerable Supratherapeutic Dose of TC-5214 After Single Ascending Oral Doses in Healthy Male Subjects, Followed by Part B: A Four-period Double-dummy Crossover Study to Investigate the Effect of 2 Single Doses (Therapeutic and Supratherapeutic) of TC-5214 on the QT/QTc Interval, Compared to Placebo, Using Moxifloxacin (Avelox®) as a Positive Control, in Healthy Male Subjects

简要总结
This is a two part study. Part A will determine the maximum tolerated dose of TC-5214 administered to healthy male subjects in single ascending oral doses. This part of the study will define the highest dose of TC-5214 to be administered in Part B. Part B of this study will investigate the effect of TC-5214 on the electrical activity of the heart following single oral administration. The study will be carried out healthy male subjects in a four period crossover study with TC-5214 compared to placebo and oral moxifloxacin as a positive control. The safety, tolerability and pharmacokinetics of TC-5214 will also be evaluated.
