Inclusion and exclusion criteria

Patients enrolled in this study will be rollover patients (those who completed the previous double-blind efficacy study C10953/3067/ES/MN) and new patients (those who did not participate in the C10953/3067/ES/MN study).

Inclusion Criteria (for New Patients):

The patient has a mild (Glasgow Coma Scale [GCS] score = 13-15) or moderate (GCS score = 9-12) closed traumatic brain injury (TBI) at the time of the injury, and the injury occurred 1 to 10 years prior to screening.
The patient has a Glasgow Outcome Scale score of 5.
The patient has an Epworth Sleepiness Scale (ESS) score of at least 10.
The patient has a mean sleep latency on the Multiple Sleep Latency Test (MSLT) (average of 4 naps) of less than 8 minutes.
The patient has a Clinical Global Impression of Severity of Illness (CGI-S) rating relating to their excessive sleepiness of 4 or more.
The patient has a complaint of excessive sleepiness (at least 5 days/week on average) for at least 3 months, and the excessive sleepiness began within 12 months of the TBI identified according to the first inclusion criterion.
Written informed consent was obtained.
If admitted to an in-patient treatment facility, the patient was discharged at least 1 month prior to the screening visit.
The patient does not have any medical or psychiatric disorders that could account for the excessive sleepiness.
Women of childbearing potential (not surgically sterile or 2 years postmenopausal), used a medically accepted method of contraception, and continued use of 1 of those methods for the duration of the study (and for 30 days after participation in the study).
The patient is in otherwise good health, as judged by the investigator, on the basis of a medical and psychiatric history, physical examination, electrocardiogram (ECG), serum chemistry, hematology, and urinalysis.
The patient is willing and able to comply with study restrictions and attend regularly scheduled clinic visits as specified in the protocol.
The patient has an mini-mental state examination (MMSE) score of more than 26 at the screening visit.
The patient was on stable dosages of medications (allowed by the protocol) for a minimum of 3 months (selective serotonin reuptake inhibitor [SSRIs] and serotonin and norepinephrine reuptake inhibitor [SNRIs]), 8 weeks (contraceptives), or 4 weeks (all other allowed medication) before the screening visit and is not likely to require a change in therapy for at least 12 weeks on the basis of the investigators' assessment.
The patient has no other head injuries that, based on medical record documentation or history from the patient and reliable informant (if available), were temporally related to the onset or to any worsening of excessive sleepiness.
The patient has no other head injury fulfilling the criteria for TBI within ±1 year of the TBI identified according to the first inclusion criterion.
The patient has a habitual bedtime between 2100 and 2400.

Inclusion Criteria (for Rollover Patients from Study C10953/3067/ES/MN):

The patient has completed 12 weeks of double-blind treatment in Study C10953/3067/ES/MN.
Written informed consent was obtained.
Women of childbearing potential (not surgically sterile or 2 years postmenopausal), used a medically accepted method of contraception and agreed to continue use 1 of those methods for the duration of the study and for 30 days after participation in the study.
The patient is in otherwise good health, as judged by the investigator, on the basis of a medical and psychiatric history, physical examination, ECG, serum chemistry, hematology, and urinalysis.
The patient is willing and able to comply with study restrictions and to remain at the clinic for the required duration during the study period, and was willing to return to the clinic for the follow-up evaluation as specified in the protocol.

Exclusion Criteria (for New Patients):

The patient has a history of 2 or more episodes of transient loss of consciousness without clear medical explanation, or has a history of known or suspected pseudo seizure (psychogenic seizure). Patients with a history of seizure or epilepsy may be eligible following discussion with the medical monitor.
The patient requires, or is likely to require, treatment with anticonvulsant medication during the study; or has taken anticonvulsant medication within 6 months before the screening visit.

The patient has had neurosurgery involving the brain or brainstem.
The patient has a history of schizophrenia, bipolar disorder, psychotic depression, or other psychotic episode.
The patient has any current Axis I disorder (including depression and posttraumatic stress disorder [PTSD]), as assessed by Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (SCID).

The patient has a known hypersensitivity to armodafinil, racemic modafinil, or any component of the study drug tablets.

The patient has a history of any clinically significant cutaneous drug reaction, or a history of clinically significant hypersensitivity reaction, including multiple allergies or drug reactions.
