Outcome Measures

Primary Outcomes (1)

  • Mean of Average Maintenance of Wakefulness Test Early for The Mode Dose of MK0249 Versus Placebo

    The Maintenance of Wakefulness Test (MWT) is an objective assessment of sleepiness that measures the ability of a patient to remain awake. The primary endpoint was the mean of sleep latency (average of the first 4 MWTs which were at 0900, 1100, 1300, and 1500), where latency for each MWT was defined as the time to onset of the first 16 continuous seconds of any stage of sleep; if no sleep was observed according to these rules, then latency was defined as 30 minutes. The comparison was for the mode dose of MK0249 versus placebo.

    At Week 2

Secondary Outcomes (4)

  • Mean of Average Maintenance of Wakefulness Test Early for the Mode Dose of MK0249 Versus Modafinil

    At Week 2

  • Mean of Average Maintenance of Wakefulness Test Early for Top 2 Doses Pooled of MK0249 Versus Modafinil

    At Week 2

  • Clinical Global Impressions Scale of Severity Score as it Relates to Excessive Daytime Sleepiness (CGIS-EDS) for the Mode Dose of MK0249 Versus Placebo

    At Week 2

  • Epworth Sleepiness Scale (ESS) Score for the Mode Dose of MK0249 Versus Placebo

    At Week 2

Interventions

Patients will be assigned to receive MK0249 film coated tablet (FCT). The doses of MK0249 that are included for possible investigation (depending upon an adaptive allocation process) are 3 mg, 5 mg, 8 mg, 10 mg, and 12 mg. Study medication will be taken for 14 days, during each of the 3 treatment periods, by mouth (po) once a day (qd).

Placebo; Patients will be assigned to receive placebo, across 3 treatment periods. Study medication will be taken for 14 days, during each of the 3 treatment periods, po qd.

123456

Patients will be assigned to receive modafinil 200mg oral compressed tablet (OCT), across 3 treatment periods. Study medication will be taken for 14 days, during each of the 3 treatment periods, po qd.
