An Efficacy Study of Compound LY2624803 in the Treatment of Patients With Chronic Insomnia (SLUMBER)

January 30, 2012 updated by: Eli Lilly and Company

A Phase 2, Randomized, Double-Blind, Placebo- and Active-Comparator-Controlled Study of the Safety and Efficacy of LY2624803 in Outpatients With Insomnia

The purpose of this study is to compare an investigational drug (LY2624803) with placebo and with zolpidem in the treatment of outpatients with chronic insomnia.

Study Overview

Detailed Description

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Average Nightly Total Sleep Time at Week 4 (Week 2 of Period B) Endpoint
Time Frame: 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. Calculated in minutes from participant-reported daily sleep questionnaire averaged across study Period B (2 weeks). Change score subtracts Period B average from Period A average (baseline). Analysis of covariance (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).
Baseline, 2 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Unwanted Time Awake at Week 4 (Week 2 of Period B) Endpoint
Time Frame: Baseline, 2 weeks
Unwanted time awake (minutes awake [MA] before sleep [between turning off the lights to first falling asleep], MA during sleep, MA after sleep before getting out of bed). Minimum would be 0; no defined maximum. The higher the number, the more the unwanted time awake. Calculated in minutes from participant-reported daily sleep questionnaire averaged (Avg.) across Period B. Change score subtracts Period B Avg. from Period A Avg. (baseline). ANCOVA Model with dependent variable being change from baseline scores and independent variables being treatment, baseline, age group, and insomnia type.
Baseline, 2 weeks
Change From Baseline in Number of Awakenings During Sleep at Week 4 (Week 2 of Period B) Endpoint
Time Frame: Baseline, 2 weeks
Elicited from participant-reported daily sleep questionnaire averaged across study Period B (2 weeks). Change score subtracts Period B average from Period A average (baseline). 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).
Baseline, 2 weeks
Change From Baseline in Total Time Awake at Week 4 (Week 2 of Period B) Endpoint
Time Frame: Baseline, 2 weeks
Calculated in minutes from participant-reported daily sleep questionnaire averaged across study Period B (2 weeks). Change score subtracts Period B average from Period A average (baseline). 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).
Baseline, 2 weeks
Change From Baseline in Sleep Efficiency at Week 4 (Week 2 of Period B) Endpoint
Time Frame: Baseline, 2 weeks
Calculated as (TIB-TTA)/TIB where TIB is time in bed and TTA is total unwanted time awake. Higher score indicates better sleep efficiency. 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).
Baseline, 2 weeks
Change From Baseline in Assessment of Sleep Quality at Week 4 (Week 2 of Period B) Endpoint
Time Frame: Baseline, 2 weeks
Assessment of Sleep Quality (ASQ) scale is asked in the participant-reported daily sleep questionnaire; 8 items on 4 point Likert scale with a range of 0 to 24. Sleep experience score ranges from 0-9; awakening experience ranges from 0-15. The higher the score, the better the sleep. Scale is averaged across study Period B (2 weeks).

Baseline (Period A) and 2 weeks (Period B)
Clinical Global Impression of Improvement (CGI-I) in Insomnia at Week 4 (Week 2 of Period B) Endpoint
Time Frame: 2 weeks
Measures clinician's perception of participant improvement at the time of assessment compared with the start of treatment. Scores range from 1 (very much improved) to 7 (very much worse). Data are presented as percentage of participants in each category.
2 weeks
Patient Global Impression of Improvement (PGI-I) in Insomnia at Week 4 (Week 2 of Period B) Endpoint
Time Frame: 2 weeks
A scale that measures the participant's perception of improvement at the time of assessment compared with the start of treatment. The score ranges from 1 (very much improved) to 7 (very much worse). Data are presented as percentage of participants in each category.
2 weeks
Change From Baseline in Total Sleep Time at Week 4 (Week 2 of Period B) Endpoint Based on Insomnia Type
Time Frame: 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.
Baseline, 2 weeks
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) Based on Insomnia Type
Time Frame: 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.
Baseline through 8 weeks
Change From Baseline in Total Sleep Time at Week 4 (Week 2 of Period B) Endpoint Based on Age Group
Time Frame: 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 age group (under age 65 versus over age 65) as originally planned because of insufficient number of elderly participants.
Baseline, 2 weeks
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) Based on Age Group
Time Frame: Baseline through 8 weeks
Number of participants with AEs and SAEs. Analyses were not performed by age group (under age 65 versus over age 65) as originally planned because of insufficient number of elderly participants.
Baseline through 8 weeks
Number of Participants With Treatment Emergent Adverse Events (TEAE)
Time Frame: 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.
Baseline through 8 weeks
Number of Participants With Serious Adverse Events (SAEs)
Time Frame: Baseline through 8 weeks
SAEs do not distinguish whether the events are treatment-emergent. A summary of SAEs is located in the Reported Adverse Event module.
