Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Histaminergic agents are known to be involved with the sleep/wake cycle. This compound is a histaminergic agent which therefore may improve alertness and awakeness in patients with excessive daytime sleepiness (EDS) associated with narcolepsy. Significant improvement in EDS when treated with this compound compared to placebo in patients with narcolepsy is hypothesized.

Placebo

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type DRUG

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.

At the end of the second arm of the study, the patient will have completed the study and have a 7-10 day follow-up visit.

Intervention Type DRUG

Each patient will receive PF-03654746 tablets in a fixed dose titration 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 the 1.0 mg dose; decrease to 0.50 mg or increase to 2.0 mg based upon the clinician's judgement regarding efficacy and side effects at the 1.0 mg dose. The patient will remain at the determined dose for a 3 week stable dosing period.
