  • A complaint of difficulty initiating or maintaining sleep or of nonrestorative sleep that lasted for at least 3 months.
  • The sleep disturbance (or associated daytime fatigue) caused clinically significant distress or impairment in social, occupational, or other important areas of functioning.
  • The disturbance did not occur exclusively during the course of narcolepsy, breathing related sleep disorder, circadian rhythm sleep disorder or a parasomnia.
  • The sleep disturbance did not occur exclusively during the course of another mental disorder (eg, major depressive disorder, generalized anxiety disorder, a delirium).
  • The disturbance was not due to the direct physiological effects of a substance (eg, a drug of abuse, a medication) or a general medical condition.
  • Based on sleep history, a subjective sleep latency (sSL) ≥45 minutes.
  • Based on sleep history, a subjective total sleep time (sTST) ≤6.5 hours.
  • Based on sleep history, a mean LPS of ≥20 minutes on 2 consecutive screening nights with neither night \<15 minutes.
  • Based on sleep history, their habitual bedtime was between 10:00 PM and 1:00 AM.
  • Able to stand with eyes closed, arms at side and feet apart at hips width for at least 1 minute with out taking a step.
  • A body mass index (BMI) between 18 and 34, inclusive.
  • +3 more criteria

  • Participated in any other investigational study and/or taken any investigational drug within 30 days or 5 half-lives prior to the first night of single-blind study medication (whichever was longer).
  • Had sleep schedule changes required by employment (eg, shift worker) within 3 months prior to the first night of single-blind study medication, or had flown across greater than 3 time zones within 7 days prior to screening.
  • Participated in a weight-loss program or had substantially altered their exercise routine within 30 days prior to the first night of single-blind study medication.
  • A history of, or currently had, conditions that would affect balance such as:
  • Orthostatic hypotension.
  • Dizziness.
  • Vertigo, or benign paroxysmal positional vertigo.
  • A history of seizures, sleep apnea, chronic obstructive pulmonary disease, restless leg syndrome, periodic leg movement syndrome, or fibromyalgia.
  • A history of psychiatric disorder (including anxiety, depression, mental retardation, cognitive disorder, bipolar illness and schizophrenia) within the past 6 months.
  • A history of drug addiction or drug abuse within the past 12 months.
  • A history of alcohol abuse within the past 12 months or regularly consumed more than 14 alcoholic drinks per week or consumed any alcoholic drinks within 24 hours of all polysomnography visits.
  • A current significant neurological (including cognitive and psychiatric disorders), hepatic, renal, endocrine, cardiovascular, gastrointestinal, pulmonary, hematological, or metabolic disease, unless currently controlled and stable with protocol-allowed medication 30 days prior to the first night of single-blind study medication.
  • Used tobacco products during nightly awakenings.
  • Used melatonin, or other drugs or supplements known to affect sleep/wake function within 1 week or 5 half-lives of the drug (whichever was longer) prior to the first day of single-blind study medication.
