What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline to Day 1&2 in Wake After Sleep Onset (WASO)
WASO was defined as the time spent in epochs scored as wake after onset of persistent sleep as determined by polysomnography (PSG) until lights on.
For WASO assessed at the study center, the mean of the 2 PSG nights at each of Visits 3 and 4 was used for Day 1\&2 and Day 15\&16
Measured: From baseline to Day 1&2
Change From Baseline to Day 15&16 in WASO
WASO was defined as the time spent in epochs scored as wake after onset of persistent sleep as determined by polysomnography (PSG) until lights on.
For WASO assessed at the study center, the mean of the 2 PSG nights at each of Visits 3 and 4 was used for Day 1\&2 and Day 15\&16
Measured: From baseline to Day 15&16
Change From Baseline to Week 1&2 in the Self-reported WASO (sWASO)
sWASO was the self-reported time spent awake after sleep onset as reported in the sleep diary. For sWASO assessed at home, the mean of all available data collected between Visits 3 and 4 (i.e., after the second morning of Visit 3 and before the first evening of Visit 4) was used for Week 1\&2
Measured: From baseline to Week 1&2
Secondary outcomes (3)
Change From Baseline to Day 1&2 in Latency to Persistent Sleep (LPS)
LPS was defined as the time from the start of the PSG recording to the beginning of the first continuous 20 epochs (i.e., 10 minutes) scored as non-wake (i.e., either sleep stage 1 (S1), sleep stage 2 (S2), slow-wave sleep (SWS), or rapid eye movement sleep(REM)) as determined by PSG
Measured: From baseline to Day 1&2
Change From Baseline to Day 15&16 in LPS
LPS was defined as the time from the start of the PSG recording to the beginning of the first continuous 20 epochs (i.e., 10 minutes) scored as non-wake (i.e., either sleep stage 1 (S1), sleep stage 2 (S2), slow-wave sleep (SWS), or rapid eye movement sleep(REM)) as determined by PSG
Measured: From baseline to Day 15&16
Change From Baseline to Week 1&2 in Subjective Latency to Sleep Onset (sLSO)
sLSO was the self-reported time to fall asleep as reported in the sleep diary
Measured: From baseline to Week 1&2

A Phase 3 study testing almorexant and zolpidem in people with Primary Insomnia, run by Midnight Pharma, LLC at 91 sites in 20 countries.
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 1 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 14 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 91 sites in Germany, Australia, France, Poland, Czechia and 15 more countries. 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 phase mean?
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 7 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?
Change From Baseline to Day 1&2 in Wake After Sleep Onset (WASO) (time frame: From baseline to Day 1&2). The study lists 3 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 NCT00608985, 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 14 Mar 2016.
