Detailed Description:

Insomnia is a common complaint or disorder throughout the world. About one third of the population in the industrial countries reports difficulty initiating or maintaining sleep, resulting in a non-refreshing or non-restorative sleep. The majority of the insomniacs suffer chronically from their complaints. The maleic acid salt of Org 4420, code name Org 50081, was selected for development in the treatment of insomnia. The first clinical trial with Org 50081 was a proof-of-concept trial with a four-way cross-over design. All 3 Org 50081 dose groups showed a statistically significant positive effect on TST (objective and subjective) and WASO, as compared to placebo. The current study is designed to assess the efficacy and safety of Org 50081 in a double-blind, placebo-controlled, parallel, randomized trial in elderly subjects suffering from chronic primary insomnia.

  • have demonstrated capability to independently complete the LogPad questionnaires and have completed the questionnaires at least 6 out of 7 days of the week preceding randomization;
  • have a regular sleep pattern, meaning bedtime regularly occurs between 2100 and 2400, with no more variation from these boundaries than 2 times/ week, with 5-8.5 hours in bed;
  • have a documented diagnosis of chronic primary insomnia, defined as fulfillment of the DSM-IV-TR criteria for primary insomnia (DSM-IV-TR 307.42) with a duration of >= 1 month; fulfill the following PSG criteria on the two screening/baseline PSG nights:
  • average TST < 6.5 h (and each night greater than or equal to 3 h and < 7 h),
  • average WASO greater than or equal to 45 minutes (and each night greater than or equal to 30 min),
