What is being measured

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

  1. Number of Participants With an Adverse Event

    An Adverse Event (AE) is any untoward occurrence in a participant who is administered any pharmaceutical product, and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding) symptom, or disease temporarily associated with the use of an investigational medicinal product (IMP), whether or not it is related to the IMP.

    Measured: Up to 57 weeks

  2. Number of Participants Who Discontinued Treatment Due to an Adverse Event

    An Adverse Event (AE) is any untoward occurrence in a participant who is administered any pharmaceutical product, and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding) symptom, or disease temporarily associated with the use of an IMP, whether or not it is related to the IMP.

    Measured: Up to 52 weeks

Secondary outcomes (6)
  1. Change From Baseline in Total Sleep Time at Week 52

    Total Sleep Time (TST) is a subjective time recorded by the participant in an electronic sleep diary in response to the question "How much time did you actually spend sleeping?". Baseline values were calculated by averaging baseline values from base trials P05706 and P05707. Data at baseline and at week 52 were collected every morning and evening for 7 consecutive days, and these data were then averaged. Missing values were imputed by the last observation carried forward (LOCF) method, where the last available assessments prior to the scheduled observation were averaged.

    Measured: Baseline and Week 52

  2. Change From Baseline in Sleep Latency at Week 52

    Sleep Latency (SL) is the time from when the participant went to bed up to the the time the participant actually fell asleep, recorded by the participant in an electronic sleep diary. Baseline values were calculated by averaging baseline values from base trials P05706 and P05707. Data at baseline and at week 52 were collected every morning and evening for 7 consecutive days, and these data were then averaged. Missing values were imputed by the LOCF method, where the last available assessments prior to the scheduled observation were averaged.

    Measured: Baseline and Week 52

  3. Change From Baseline in Wake Time After Sleep Onset at Week 52

    Wake time after sleep onset (WASO) is, if the planned waking time is on or after the time of final awakening, as follows: total time from falling asleep to the time of planned wake up minus the total sleep time. If the planned waking time is before the time of final awakening then WASO is as follows: total time from falling asleep to the time of actual final awakening minus the total sleep time. All times were recorded by the participant in an electronic sleep diary. Baseline values were calculated by averaging baseline values from base trials P05706 and P05707. Data at baseline and at week 52 were collected every morning and evening for 7 consecutive days, and these data were then averaged. Missing values were imputed by the LOCF method, where the last available assessments prior to the scheduled observation were averaged.

    Measured: Baseline and Week 52

  4. Change From Baseline in Number of Awakenings at Week 52

    Number of awakenings is a subjective number recorded by the participant in an electronic sleep diary. Baseline values were calculated by averaging baseline values from base trials P05706 and P05707. Data at baseline and at week 52 were collected every morning and evening for 7 consecutive days, and these data were then averaged. Missing values were imputed by the LOCF method, where the last available assessments prior to the scheduled observation were averaged.

    Measured: Baseline and Week 52

  5. Change From Baseline in Quality of Sleep Scale at Week 52

    Quality of Sleep is a subjective number on a Visual Analog Scale recorded by the participant in an electronic sleep diary. The scale ranges from 0 to 100, where very poor is rated at 0, up to excellent, rated at 100. Baseline values were calculated by averaging baseline values from base trials P05706 and P05707. Data at baseline and at week 52 were collected every morning and evening for 7 consecutive days, and these data were then averaged. Missing values were imputed by the LOCF method, where the last available assessments prior to the scheduled observation were averaged.

    Measured: Baseline and Week 52

  6. Change From Baseline in Satisfaction With Sleep Duration Scale at Week 52

    Satisfaction with Sleep Duration is a subjective number on a Visual Analog Scale recorded by the participant in an electronic sleep diary. The scale ranges from 0 to 100, where very unsatisfied is rated at 0, up to fully satisfied, rated at 100. Baseline values were calculated by averaging baseline values from base trials P05706 and P05707. Data at baseline and at week 52 were collected every morning and evening for 7 consecutive days, and these data were then averaged. Missing values were imputed by the LOCF method, where the last available assessments prior to the scheduled observation were averaged.

    Measured: Baseline and Week 52

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Org 50081 in people with Insomnia, run by Merck Sharp & Dohme LLC.

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 3 inclusion and 4 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 3 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

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 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 30 Jul 2014). 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?

Number of Participants With an Adverse Event (time frame: Up to 57 weeks). 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?
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 3 Oct 2018.
