The effect of multiple oral doses of lorcaserin 15 mg and 40 mg once daily on QTc
interval was evaluated in a randomized, placebo- and active- (moxifloxacin 400 mg) controlled four-treatment
arm parallel thorough QT study in 244 healthy subjects. In a study with demonstrated ability to detect small
effects, the upper bound of the one-sided 95% confidence interval for the largest placebo adjusted, baselinecorrected QTc based on individual correction method (QTcI) was below 10 ms, the threshold for regulatory
concern.
