ClinicalTrials.gov Identifier:
First received: December 4, 2008
Last updated: February 5, 2016
Last verified: February 2016

Primary objective:

- To assess the efficacy of eplivanserin 5mg/day in comparison to placebo after 6 weeks of treatment on sleep maintenance of insomniac patients, as measured by Polysomnography Wake Time After Sleep Onset (PSG-WASO) and Polysomnography Number of Awakenings (PSG-NAW).

Secondary objectives:

  • To evaluate the effects of eplivanserin 5mg/day as compared to placebo after 6 weeks of treatment on other sleep parameters measured by PSG recordings (Total Sleep Time - PSG-TST, Sleep Efficiency - PSG-SE, Latency to Persistent Sleep - PSG-LPS) and reported by patients (Wake Time After Sleep Onset - pr-WASO, Number of Awakenings - pr-NAW, Total Sleep Time - pr-TST, Quality of Sleep - QoS and Refreshing Quality of Sleep - RqoS).
  • To evaluate the effects of eplivanserin 5mg/day on sleep architecture compared to placebo.
  • To evaluate the effect of eplivanserin 5mg/day on daytime functioning using the Sleep Impact Scale (SIS), as compared with placebo after 6 weeks of treatment.
  • To evaluate patient's impression of treatment effects using the Patient's Global Impression questionnaire.
  • To evaluate the potential for next-day residual effects (using patient's morning questionnaire and psychometric tests) with eplivanserin 5mg/day as compared to placebo.
  • To evaluate the potential for rebound insomnia following abrupt discontinuation of eplivanserin 5mg/day in comparison with placebo.
  • To evaluate the effect of eplivanserin, compared to placebo, on the quality of life of patients with primary insomnia using the SF-36 Health Survey.
  • To evaluate the clinical safety and tolerability of eplivanserin 5mg/day compared to placebo.

Primary Outcome Measures:
  • Change from baseline of mean PSG-WASO on N41/N42 [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Change from baseline of mean PSG-NAW on N41/N42 [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Other PSG sleep parameters: PSG-TST, PSG-SE (TST/Time in Bed), PSG-LPS [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Patient-reported sleep parameters [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Patient Global impression (PGI) [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
  • sleep architecture: percentage of time spent in each sleep stage (1, 2, 3-4/SWS, REM), shift to stage 1, shift to wake, stage 1 + WASO, [stages 3&4]/[stage 1 + WASO]). [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
  • Sleep Impact Scale (SIS) [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
  • SF-36 Health Survey [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
