Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Dose-response relationship of PD 200390 on wake after sleep onset (WASO) in subjects with primary insomnia as determined by Polysomnography [ Time Frame: weekly ]

Secondary Outcome Measures:
  • Subjective assessments of wake after sleep onset (sWASO), latency to sleep onset (LSO), number of awakenings after sleep onset (sNAASO), total sleep time (TST), and sleep quality via questionnaire. [ Time Frame: weekly ]
  • Subjective assessment of sleep with Leeds Sleep Evaluation Questionnaire-LSEQ. [ Time Frame: weekly ]
  • PSG efficacy assessments including number of awakenings after sleep onset (NAASO), number of arousals, total sleep time (TST), sleep efficiency (SE), total wake time (TWT) [ Time Frame: weekly ]
  • Latency to persistent sleep (LPS) as determined by Polysomnography [ Time Frame: weekly ]
