Intervention

Drug:
• Comparator: MK0249
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).
• Comparator: placebo
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.
• Comparator: modafinil
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	No
Secondary	Mean of Average Maintenance of Wakefulness Test Early for the Mode Dose of MK0249 Versus Modafinil	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 modafinil.	At Week 2	No
Secondary	Mean of Average Maintenance of Wakefulness Test Early for Top 2 Doses Pooled of MK0249 Versus Modafinil	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 top 2 doses pooled of MK0249 versus modafinil.	At Week 2	No
Secondary	Clinical Global Impressions Scale of Severity Score as it Relates to Excessive Daytime Sleepiness (CGIS-EDS) for the Mode Dose of MK0249 Versus Placebo	Clinical Global Impressions Scale of Severity (CGI-S) is a subscale of the CGI which is a standard psychometric scale used to demonstrate changes and improvements in illness. CGI-S consists of a 7-point scale rated from 1 to 7. The investigator or sponsor-approved clinician judged how ill the patient was with respect to Excessive Daytime Sleepiness (EDS) at the time of the CGI-S rating (CGIS-EDS), with higher scores indicating more severe illness.	At Week 2	No
Secondary	Epworth Sleepiness Scale (ESS) Score for the Mode Dose of MK0249 Versus Placebo	The Epworth Sleepiness Scale (ESS) is a self-administered questionnaire that provides subjective reports that equate with sleep propensity, not with 'subjective sleepiness'. Having a high sleep propensity means having a history of dozing in situations that have a relatively low soporific nature, in which normal subjects seldom doze. The ESS consists of eight items, which are rated from 0 ("would never dose") to 3 ("high chance of dozing"). The ESS score is the total score of the 8 individual items; this total score ranges from 0 to 24 (higher total score is worse).	At Week 2	No
