Arm Type

Experimental

Placebo Comparator

Arm Label

Sodium Oxybate

Placebo

Arm Description

Patients will undergo a screening period and will then be titrated to the following once-nightly doses: 4.5 g sodium oxybate, 6.0 g sodium oxybate, 7.5 g sodium oxybate, and 9.0 g sodium oxybate.

Patients will undergo a screening period and will then be titrated to the following once-nightly doses: 4.5 g placebo, 6.0 g placebo, 7.5 g placebo, and 9.0 g placebo.

Outcomes

Primary Outcome Measures

Maintenance of Wakefulness Test (MWT)
Change from Baseline for MWT, which is the mean latency across 5 naps, averaged over the test day
Proportion of Patients That Were Very Much Improved or Much Improved on Clinical Global Impression of Improvement as Compared to Screening
The CGI is the clinician's global impression of improvement in daytime sleepiness. For the CGI, a GLIMMIX (generalized linear mixed models) model for binomial data with logit link was used to analyze the categorized CGI response, i.e., the proportions of subjects who were Very Much Improved or Much Improved as compared to Screening
Number of Cataplexy Attacks at Visit 8 (Week 14) as Compared to Baseline
Mean number of cataplexy events recorded on the Sleep and Symptom Daily Diary during the period
