Primary Outcome Measures:
  • To demonstrate efficacy and characterize the dose response relationship of PD 0200390 on subjective wake after sleep onset in subjects with primary insomnia. [ Time Frame: Weekly ]

Secondary Outcome Measures:
  • To characterize the dose response relationship of PD 0200390 on functional outcome measures in subjects with primary insomnia. [ Time Frame: Weekly ]
  • To characterize the exposure response relationship of safety & efficacy parameters following administration of PD 0200390 in subjects with primary insomnia. [ Time Frame: Weekly ]
  • To investigate the potential for rebound insomnia and withdrawal effects after discontinuation of PD 0200390 in subjects with primary insomnia. [ Time Frame: Weekly ]
  • To characterize the dose response relationship of PD 0200390 on subjective assessments of latency to sleep onset (LSO), number of awakenings after sleep onset (sNAASO) and total sleep time (sTST) in subjects with primary insomnia. [ Time Frame: Weekly ]
  • To investigate the safety and tolerability of PD 0200390 administered once daily before bedtime in subjects with primary insomnia. [ Time Frame: Weekly ]
