  • Patients treated with sodium oxybate (Xyrem®) with a stable dosage for at least 2 months prior to the trial.
  • Patients complaining of residual EDS
  • Patient should be free of non authorized drugs or discontinue any psychostimulant medication at least 3 weeks before randomization (V2).
  • Females of child-bearing potential must use a medically accepted effective method of birth control, agree to continue this method for the duration of the study and be negative to serum pregnancy test performed at the screening visit. Females should not be breast-feeding patient.
  • In the opinion of the investigator, the patient must have adequate support to comply with the entire study requirements as described in the protocol (e.g. transportation to and from trial site, self rating scales, drug compliance, scheduled visits, etc).
  • Patient must have voluntarily expressed a willingness to participate in this study, signed and dated an informed consent prior to beginning this protocol required procedures.

Exclusion Criteria:

  • Psychiatric and neurological disorders, other than narcolepsy/cataplexy, such as moderate or severe psychosis or dementia, bipolar illness, severe anxiety, clinical severe depression (BDI ≥ 16) with suicidal risk (item G BDI > 0), or depression treated for less than 8 weeks, history of seizure disorder or other problem that in the investigator's opinion would preclude the patient's participation and completion of this trial or comprise reliable representation of subjective symptoms.
  • Patients working in an occupation requiring variable shift work or routine night shifts.
  • Patients with an untreated sleep apnea disorder (defined as an apnea index > 10/h or an apnea/hypopnea index>15/h) or who have any other cause of daytime sleepiness.
  • Use of hypnotics, tranquilizers, sedating antihistamines, psychostimulants for the treatment of EDS (amphetamine and amphetamine-like CNS stimulants, modafinil, methylphenidate or others), benzodiazepines, anticonvulsants or clonidine will not be accepted at least 3 weeks before randomization (V2) and during study.
  • Current or recent (within one year) history of a substance abuse or dependence disorder including alcohol abuse as defined in Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).
  • Other active clinically significant illness, including unstable cardiovascular, or neoplasic pathology which could interfere with the study conduct or counter-indicate the study treatments or place the patient at risk during the trial or compromise the study participation.
  • Patient with a known history of long QTc syndrome (e.g. syncope or arythmia) or presenting any significant serious abnormality of the ECG (e.g. recent myocardial infarction), or QTc interval strictly higher than 450 ms (electrocardiogram Bazett's corrected).
  • Patients with Severe Hepatic Impairment or with Severe Renal Impairment, or with any other significant abnormality in the physical examination or clinical laboratory results.
  • Known hypersensitivity to the tested treatment including active substance and excipients.
  • Patients participating in an other study and the use of any investigational therapy within the 30 days prior to the entry in this study.
