A Study Of A Novel Compound For Excessive Daytime Sleepiness Associated With Narcolepsy

Patients receiving placebo will undergo the same procedures as those receiving active treatment. Each patient will receive matching placebo tablets in a fixed dose escalation schedule beginning at 0.25 mg QD for 5 days; then up to 0.50 mg QD for another 5 days; and up to 1.0 mg QD for an additional 5 days. At the end of this fixed titration schedule, the patient will either stay at 1.0 mg; decrease to 0.5 mg or increase to 2.0 mg based upon the clinicians judgment regarding efficacy and side effects at the 1.0 dose level. The patient will then remain at the determined dose for a 3 week stable dosing period, with a 7 (-2/+ 9) day wash out and then crossover to repeat the same sequence for the second arm of the study.
