Outcome Measures
Primary Outcomes (1)
Sleep latency (in minutes), as measured by the Maintenance of Wakefulness Test (MWT), at the end of the DBP
Sleep latency was measured at the end of DBP (Day 42) by an extended version of the MWT which was used to measure the ability of a participant to remain awake. The MWT consisted of four 40-minutes trails performed at two hour intervals and the main MWT score was mean sleep latency (arithmetic mean of the four 40-minutes trials). Trials were ended after 40 minutes if no sleep occurred, or after unequivocal sleep, defined as three consecutive epochs of stage 1 sleep, or one epoch of any other stage of sleep. Least square mean was used to present the value for adjusted mean.
Day 42
Secondary Outcomes (54)

Baseline (Day -1) and Day 28
Change from End of OLP (Day 28) in Sleep latency (minutes), as measured by the MWT to the end of the DBP (Day 42)

Baseline (Day -1) up to Day 28
Change from Baseline in severity of Cataplexy Attacks during the OLP
Baseline (Day -1) up to Day 28
