About this study
Official title: A Phase II/III Study of SEP-190 (Eszopiclone) in Patients With Primary Insomnia
The purpose of this study is to investigate and evaluate the efficacy of Eszopiclone in Japanese participants with primary insomnia.
Read the detailed description
This is a multicenter, randomized, double-blind, placebo-controlled, 5-way cross-over study to investigate and evaluate the efficacy of eszopiclone in Japanese participants with primary insomnia. The treatment period consists of two consecutive days (two nights) as one term. Patients will receive oral eszopiclone (1, 2, 3 mg), zolpidem tartrate (10 mg), or placebo once daily at bedtime for each use. Participants were randomly assigned to one of 10 prespecified treatment sequence patterns.

What is being measured
The primary outcome is the main question the study is designed to answer.
Latency To Persistent Sleep (LPS)
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.
Measured: 10 days (5 intervals of two consecutive nights)
Sleep Latency (SL)
The subjective measure, SL, defined as the amount of time measured in minutes it takes to fall asleep was based on participant-reported subjective assessments of sleep disturbance and was obtained from participants' responses to morning questionnaires. Questionnaires were administered during each visit during the treatment period.
Measured: 10 days (5 intervals of two consecutive nights)
Secondary outcomes (4)
Total Sleep Time (Objective & Subjective)
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.
The subjective measure was based on participant-reported subjective assessments of sleep disturbance and were obtained from participants' responses to morning questionnaires. Questionnaires were administered during each visit during the treatment period.
Measured: 10 days (5 intervals of two consecutive nights)
Sleep Efficiency
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. PSG recording duration for scoring was 8 hours. PSG data recorded during treatment were centrally scored by a trained expert.
Measured: 10 days (5 intervals of two consecutive nights)
Wake Time After Sleep Onset (WASO)- Objective & Subjective
Wake Time After Sleep Onset (WASO) defined as total awakening time from falling asleep to final awakening was objectively determined by polysomnography and subjectively determined based on participant-reported measures following treatment.
The objective WASO 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.
The subjective measure was based on participant-reported subjective assessments and were obtained from participants' responses to morning questionnaires. Questionnaires were administered during each visit during the treatment period.
Measured: 10 days (5 intervals of two consecutive nights)
Number of Awakenings (Objective & Subjective)
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.
The subjective measure was based on participant-reported subjective assessments and were obtained from participants' responses to morning questionnaires. Questionnaires were administered during each visit during the treatment period.
Measured: 10 days (5 intervals of two consecutive nights)

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Eszopiclone 1 mg, Eszopiclone 2 mg and Eszopiclone 3 mg in people with Primary Insomnia, run by Eisai Co., Ltd. at 20 sites in Japan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 20 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 Feb 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Latency To Persistent Sleep (LPS) (time frame: 10 days (5 intervals of two consecutive nights)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00770510, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2013; AzTrials last refreshed its copy on 7 Nov 2026.
