About this study

Official title: Refinement Of Patient Reported Outcomes Instruments In Subjects With Insomnia Characterized By Nonrestorative Sleep

To begin to refine development of the RSQ (Restorative Sleep Questionnaire) measure in subjects with NRS (Nonrestorative Sleep) by generating item content pertaining to morning refreshment and uncovering problems in instrument administration in subjects with nonrestorative sleep

Read the detailed description

Study was terminated on January 20, 2009 due to portfolio decision by Pfizer to discontinue further investigation of PD200390 for non-restorative sleep. The decision was not based on any safety concerns.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PSGProcedure or surgery

    PSG (polysomnography) for adaptation night, day 2 evening, and day 3 evening--used to identify suitable Nonrestorative Sleep candidates to participate in focus groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Once subjects identified, a series of focus group sessions will be held to identify concepts, themes and items relevant to Nonrestorative Sleep.

    Measured: monthly

  2. To begin to refine the development of the RSQ measure in subjects with Nonrestorative Sleep by generating item content pertaining to morning refreshment and uncovering problems in instrument administration in subjects with nonrestorative sleep.

    Measured: nightly

  3. Identification of subjects with insomnia characterized by Nonrestorative Sleep only [assessed via LPS (latency to persistent sleep onset) and WASO (Wake after sleep onset) as determined by PSG (polysomnography)].

    Measured: nightly

Secondary outcomes (3)
  1. Subjective measures include MAF (multidimensional assessment of fatigue), Sheehan Disability Scale, SF36v2, Endicott Work productivity scale (EWPS) Global impression of severity (CGIS) and the Profile of mood states.

    Measured: nightly

  2. Secondary assessments to characterize the functional impact of insomnia including Nonrestorative Sleep include additional PSG (polysomnography) variables.

    Measured: nightly

  3. After phase IIa of this study, a questionaire to be designed - Participants to be debriefed, and interviewed to assess the content validity of the questionnaire.

    Measured: monthly
