Inclusion Criteria
- •Written informed consent is obtained from each patient's parent or legal guardian and written assent is obtained from each patient.
- •The patient is a male or female 6 through 17 years of age with a body mass index (BMI) equal to or greater than 10th percentile for age and gender, inclusive.
- •The patient has a diagnosis of narcolepsy with cataplexy or narcolepsy without cataplexy according to the criteria established by the International Classification of Sleep Disorders (ICSD)-2 for narcolepsy.
Exclusion Criteria

- •The patient has a clinically significant deviation from normal in ECG, physical examination or vital sign findings, as determined by the investigator or medical monitor.
- •The patient is pregnant or lactating. (Any patient becoming pregnant during the study will be withdrawn from the study)
- •The patient has any history of seizures, including febrile seizures, or a family history of seizures (in parents or siblings) which is not a consequence of trauma, stroke, or metabolic disturbance.
- •The patient has a history of head trauma associated with loss of consciousness.

- •The patient has a history of major depressive disorder, bipolar disorder, other significant mood disorders, schizophrenia and other psychotic disorders, eating disorders, or has a family history of suicide.
- •The patient has left ventricular hypertrophy or the patient has mitral valve prolapse and has experienced mitral valve prolapse syndrome.
- •The patient has received any investigational drug within 30 days or 5 half-lives (whichever is longer) before the 1st dose of study drug, or in the case of a new chemical entity, 3 months or 5 half-lives (whichever is longer) before the 1st dose of study drug.
- •The patient has used any monoamine oxidase inhibitors (MAOIs) or stimulants within 14 days or 5 half-lives (whichever is longer) of the baseline visit.
Arms & Interventions
Armodafinil 50 mg
In period 1, patients will receive a single 50-mg dose of armodafinil on day 1. In period 2, patients will receive a single 50-mg dose daily on days 1 through 42.
Intervention: Armodafinil

In period 1, patients will receive a single 100 mg dose of armodafinil on day 1. In period 2, patients will receive a single 50-mg dose on day 1 then daily 100-mg doses on days 2 through 42.
Intervention: Armodafinil
Armodafinil 150 mg
In period 1, patients will receive a single 150-mg dose of armodafinil on day 1. In period 2, patients will receive a single 50-mg dose on day 1, 100-mg doses on days 2 and 3, then daily 150-mg doses on days 4 through 42.
Intervention: Armodafinil
