Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study will characterize the effect of armodafinil on driving simulator performance. The effects of armodafinil compared to placebo will be studied in a double blind crossover trial involving 10 healthy subjects with serial assessments at baseline and after extensive sleep deprivation. Using simultaneous electroencephalogram (EEG) recording during simulated driving and neurocognitive assessments of vigilance, the relationship between brain activity and cognitive performance will be established.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Following the acclimation session, the resting baseline for the subjects will be measured which will consist of a simultaneous assessment of cognitive performance and brain activity. The subjects will first drive for 30 minutes on the driving simulator to establish a resting baseline of the driving performance. Afterwards a resting baseline for cognitive tests will be established to measure attention, vigilance, risk-taking and decision-making. EEG will be recorded concurrently during driving and cognitive tests. No blood samples will be taken during the assessment of the resting baseline. Subjects will be discharged from the CRC after completion of the baseline session (approximately 2 hours) until the evening. During this time subjects are not allowed to sleep and they will be informed to not consume any caffeine containing products (e.g. Red Bull, coffee). Upon return to the CRC, the subjects will be sleep deprived and supervised by at least one of the study coordinators and at least one additional person to make sure the subjects don't fall asleep during the night.
The following day, 24 hours after the resting baseline session, the fatigue baseline session will start. Sessions of resting baseline and fatigue baseline will be scheduled for the same time of day on two consecutive days to account for circadian alignment. The testing procedure will be identical to the resting baseline session that means subjects will drive for 60 minutes on the driving simulator and perform the same cognitive tests as in the baseline session. After completion of the fatigue baseline session, the study drug (armodafinil 250 mg or placebo) will be administered. To determine the pharmacokinetics, blood samples will be obtained prior to drug dosing and at 0.5, 1, 1.5, 2, 3, 4, 6, 8 and 10 hours post-dose through an intravenous catheter placed in the arm vein of the subjects. After study drug intake subjects will perform 5 sessions on the driving simulator consisting of 30-minute drives. The same battery of tests performed at baseline will be performed between the drives. The tested cognitive abilities play an important role during driving and the investigators will investigate to what extent sleep deprivation alters these abilities and how armodafinil is able to counter the deteriorating effects of sleep deprivation on these capabilities.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Body mass index (BMI) from 18.5 to 29.9 kg/m2, inclusive.
3. A valid driver's license.
4. Healthy on the basis of physical examination, medical history, vital signs.
5. Absence of clinically significant abnormalities in the subject's sleep history. The study physician will base this decision on the Epworth Sleepiness Scale and a discussion with the subject about his or her sleep history.
6. Female subjects must be postmenopausal (for at least 6 months), surgically sterile, or abstinent; or, if of childbearing potential and sexually active, be practicing an effective method of birth control (e.g., intrauterine device, double-barrier method, male partner sterilization) before entry and throughout the study; have a negative urine pregnancy test at screening, and a negative urine pregnancy test prior to each experimental session. Steroidal contraceptives have been shown to interact with the study drug and are not an acceptable form of contraception for this study (subjects taking steroidal contraceptive drugs are ineligible for this study).
7. Agree not to consume any alcohol 24 hours prior to any study session and until discharge from the unit.
8. Agree not to consume any grapefruit or grapefruit juice 24 hours prior to dosing and until discharge from the unit.
9. Agree not to use armodafinil or modafinil-containing medications 2 weeks prior to or during any study session (aside from what is administered for the study).
10. Agree not to use any other medication that acts on the central nervous system (prescription or nonprescription) 1 week prior to or during any study session (caffeine is the only exception, subjects are recommended to avoid caffeine for one week prior to a study session, but are required to avoid caffeine for 24 hours prior to and during a study session).
