Trial Outcomes & Findings for A Phase II/III Study of SEP-190 (Eszopiclone) in Patients With Primary Insomnia (Study 190-126) (NCT NCT00770510)

NCT ID: NCT00770510

Last Updated: 2013-02-04

Results Overview

The objective measure, LPS, defined as the amount of time measured in minutes it takes to fall asleep was based on polysomnography (PSG) objective assessments of sleep disturbance. PSG recording was performed according to a manual for overnight PSG. The start time for PSG recording was individualized and scheduled within +/- 30 minutes of the participant's median bedtime as recorded in the sleep diary. During the screening period, participants were provided a diary in which they recorded the time of lights out before bedtime for 1 week pror to PSG evaluations. PSG recording duration for scoring was 8 hours. PSG data recorded during treatment were centrally scored by a trained expert.

Timeframe: 10 days (5 intervals of two consecutive nights)

Population: Full analysis set: includes randomized participants who were administered \>= 1 dose of study medication and had evaluable data for the primary efficacy assessments from any of the 5 treatment intervals.

Total sleep time defined as total sleeping time from bedtime to final awakening (measured in minutes) was objectively determined by polysomnography and subjectively determined based on participant-reported measures following treatment. The objective total sleep time was based on PSG-based assessments. PSG recording was performed according to a manual for overnight PSG. The start time for PSG recording was individualized and scheduled within +/- 30 minutes of the participant's median bedtime as recorded in the sleep diary. PSG recording duration for scoring was 8 hours. PSG data recorded during treatment were centrally scored by a trained expert.

Population: Full analysis set: includes randomized participants who were administered \>= 1 dose of study medication and had evaluable data for the primary efficacy assessments from any of the 5 treatment intervals.

Sleep efficiency (SE) was an assessment obtained from PSG during the treatment period and was defined as the ratio of total sleep time to the total time in bed of 8 hours \* 100, expressed as a percent. PSG recording was performed according to a manual for overnight PSG. The start time for PSG recording was individualized and scheduled within +/- 30 minutes of the patient's median bedtime as recorded in the sleep diary. During the screening period, participants were provided a diary in which they recorded the time of lights out before bedtime for 1 week pror to PSG evaluations.

Number of awakenings defined as the total number of spontaneous awakenings from falling asleep to final awakening was objectively determined by polysomnography and subjectively determined based on participant-reported measures following treatment. The objective number of awakenings was based on PSG assessments. PSG recording was performed according to a manual for overnight PSG. The start time for PSG recording was individualized and scheduled within +/- 30 minutes of the participant's median bedtime as recorded in the sleep diary. PSG recording duration for scoring was 8 hours. PSG data recorded during treatment were centrally scored by a trained expert.
