What is being measured

The primary outcome is the main question the study is designed to answer.

Change in Wake After Sleep Onset (WASO) From Baseline to Days 1 and 2
WASO is the time in minutes spent awake after onset of persistent sleep until lights on as determined by polysomnography (PSG)
Measured: Baseline to Day 1 and Day 2 of each treatment period

Secondary outcomes (1)

Change in Mean Latency to Persistent Sleep (LPS) From Baseline to Days 1 and 2
LPS is the duration of time in minutes from lights off to persistent sleep onset as determined by PSG
Measured: Baseline to Day 1 and Day 2 of each treatment period

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ACT-541468 in people with Insomnia Disorder, run by Idorsia Pharmaceuticals Ltd. at 10 sites in 2 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 7 inclusion and 10 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 24 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States, Germany. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 24 Apr 2020). 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 in Wake After Sleep Onset (WASO) From Baseline to Days 1 and 2 (time frame: Baseline to Day 1 and Day 2 of each treatment period). 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 NCT02841709, 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 24 Apr 2020; AzTrials last refreshed its copy on 8 Nov 2026.
