Study Summary

This will be a randomized, double-blind, placebo- controlled cross-over study to investigate the effect of GEn on cardiac repolarisation parameters compared with placebo and a positive control, moxifloxacin. Approximately 52 subjects will be recruited to the study and will take part in four dosing sessions. Subjects will receive, in a randomized order, a single dose of 1200 mg GEn, 6000 mg GEn (supratherapeutic dose), 400 mg moxifloxacin (positive control) and placebo. Twelve lead continuous ECG monitoring will be conducted from pre-dose to approximately 24 hours after dosing on Day 1 of each study session. The primary comparison of interest will be the mean change from baseline in the time-matched differences in QTcF between each GEn treatment and placebo.
