Summary:

      The primary objective of this study is to determine whether treatment with Armodafinil
      (CEP-10953) is more effective than placebo treatment for patients with residual excessive
      sleepiness associated with obstructive sleep apnea/hypopnea syndrome (OSAHS) by measuring
      mean sleep latency from the Maintenance of Wakefulness Test (MWT) (30 minute version)
      (average of 4 naps at 0900, 1100, 1300, and 1500) and by Clinical Global Impression of Change
      (CGI C) ratings (as related to general condition) at week 12 (or last postbaseline visit).
    

Eligibility criteria:

        Diagnosis and Criteria for Inclusion: Patients are included in the study if all of the
        following criteria are met:

          1. Written informed consent is obtained.

          2. The patient is an outpatient, man or woman of any ethnic origin, 18 to 65 years of age
             (inclusive).

          3. The patient has a complaint of excessive sleepiness despite nCPAP therapy being
             effective and being a regular user of nCPAP therapy.

          4. The patient has a current diagnosis of OSAHS according to International Classification
             of Sleep Disorders (ICSD) criteria.

          5. The patient meets the following nCPAP therapy requirements:

               -  Adequate education and intervention efforts to encourage nCPAP therapy use must
                  be documented.

               -  A patient's nCPAP therapy regimen must be stable for at least 4 weeks.

               -  nCPAP therapy is shown to be effective, with effectiveness defined as having an
                  apnea hypopnea index (AHI) of 10 or less during nocturnal PSG, and, in the
                  opinion of the investigator, nCPAP is effective therapy.

               -  Following demonstration of effectiveness, evidence of regular nCPAP usage must be
                  shown during a 2 week evaluation period (ie, nCPAP usage for at least 4
                  hours/night on at least 70% of the nights).

          6. The patient is in good health as determined by a medical and psychiatric history,
             physical examination, ECG, and serum chemistry and hematology.

          7. Women must be surgically sterile, 2 years postmenopausal, or, if of child bearing
             potential, using a medically accepted method of birth control (ie, barrier method with
             spermicide, steroidal contraceptive [oral, implanted, and Depo Provera contraceptives
             must be used in conjunction with a barrier method], or intrauterine device [IUD]) and
             agree to continued use of this method for the duration of the study.

          8. The patient has a Clinical Global Impression of Severity of Illness (CGI S) rating of
             4 or more.

          9. The patient has an ESS score of 10 or more.

         10. The patient does not have any medical or psychiatric disorders that could account for
             the excessive sleepiness.

         11. The patient is able to complete self rating scales and computer based testing.

         12. The patient is willing and able to comply with study restrictions and to attend
             regularly scheduled clinic visits as specified in this protocol.
