Study Summary

The primary purpose of the study is to demonstrate that lorcaserin has superior efficacy compared to placebo on percent change in frequency of convulsive seizures per 28 days in participants with Dravet syndrome.

Primary Outcome

Seizure frequency for convulsive seizures was based on number of seizures per 28 days, calculated during the baseline period (Week -4 to Week 0) and 14-week treatment period, as the number of seizures during each respective period divided by the number of non-missing days during each respective period, multiplied by 28. Percent change from baseline was calculated as: (\[post-baseline value minus the baseline value\] / baseline value) \*100.
