Descrição detalhada
Outpatients with chronic insomnia who participate in this study will be treated in each of four 2-week treatment periods with bedtime doses of either placebo, zolpidem, LY2624803 1 mg, or LY2624803 3 mg.
Neither patients nor investigators will be told what treatments are being given in any treatment period.
A patient who completes all four treatment periods will be treated with placebo in 1, 2, or 3 of the periods; with zolpidem in 0, 1, or 2 of the periods; and with LY2624803 in either 1 or 2 of the periods.
No patient will receive placebo for all four of the 2-week treatment periods.
All patients will receive LY2624803 for at least one of the four 2-week treatment periods.
During each treatment period, patients will record information each morning about their sleep the night before, and each evening about their functioning since waking up.
Patients will also wear wrist actigraphy devices to record their physical activity.
At the conclusion of each treatment period, patients will answer questions about their sleep, functioning, health, and relative preference for treatments.

Change From Baseline in the Insomnia Severity Index (ISI) at Week 4 (Week 2 of Period B) Endpoint
Prazo: Baseline, 2 weeks
|
The ISI is a brief self-report instrument that measures a participant's perception of his or her insomnia.
7 questions on 5-point Likert scale with minimum of 0 and maximum of 28.
The higher the score, the more severe the insomnia.
It was collected at the bi-weekly office visits.
ANCOVA Model with dependent variable being change from baseline scores and independent variables being treatment, baseline, age group (<65 or ≥65), and insomnia type (primary vs. secondary).

Change From Baseline in Physical and Mental Component Scores as Measured by the Short Form 12 (SF-12) Version 2 at Week 4 (Week 2 of Period B) Endpoint
Prazo: Baseline, 2 weeks
|
The SF-12 is a subset of 12 items from the Medical Outcomes Study 36-Item Short Form Survey (SF-36) and was collected at the bi-weekly office visits.
Each score ranges from 0-100.
The components measure physical and mental health, respectively.
Higher scores are indicative of better function.

Change From Baseline in Health-related Quality of Life as Measured by European Quality of Life (EuroQol) at Week 4 (Week 2 of Period B) Endpoint
Prazo: Baseline, 2 weeks
|
The EuroQoL Questionnaire-5 Dimension (EQ-5D) is a generic, multidimensional, health-related, quality-of-life instrument.
The profile allows participants to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and mood.
The score ranges 0-100.
The higher score indicates a better health state perceived by the participant.

Change From Baseline in Total Sleep Time at Week 4 (Week 2 of Period B) Endpoint Based on Insomnia Type
Prazo: Baseline, 2 weeks
|
Total Sleep Time is defined as time in bed minus total time awake.
Minimum would be 0; no defined maximum (except if as defined as time in bed).
The higher the number, the more time asleep.
Analyses were not performed by insomnia type (primary versus secondary) as originally planned because of insufficient number of secondary insomnia participants.

|
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) Based on Insomnia Type
Prazo: Baseline through 8 weeks
|
Number of participants with AEs and SAEs.
Analyses were not performed by insomnia type (primary versus secondary) as originally planned because of insufficient number of secondary insomnia participants.

Number of Participants With Treatment Emergent Adverse Events (TEAE)
Prazo: Baseline through 8 weeks
|
Treatment Emergent Adverse Events (TEAEs) are defined as AEs that first occurred or worsened during the treatment period.
TEAEs are summarized by study period and treatment group.
TEAEs do not distinguish whether the events were deemed serious.
A summary of non-serious AEs is located in the Reported Adverse Event module.
