What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EsmirtazapineDrug

    Also called Org 50081, MK-8265

    Esmirtazapine maleate was provided as tablets for oral use containing either 1.5, 3.0, or 4.5 mg of active compound. In addition, tablets contain the following excipients: hydroxypropyl cellulose, maize starch (United States Pharmacopeia [USP] name: corn starch), magnesium stearate, and lactose monohydrate. Tablets were administered orally once daily about 30 minutes prior to bedtime.

What is being measured

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

  1. Average Total Sleep Time (TST) as Recorded Daily in the Sleep Diary During the 14-day In-treatment Period

    TST was defined as the total amount of time (measured in minutes) that was actually spent sleeping the previous night as recorded daily in the participant's sleep diary. TST values over the 14-day active treatment period were averaged for each participant, and average TST was then reported by treatment arm. For participants with missing data, the average of the nights for which TST data were present was used in the analysis.

    Measured: Day 1 to Day 15

Secondary outcomes (3)
  1. Average Sleep Latency (SL) as Recorded Daily in the Sleep Diary During the 14-day In-treatment Period

    SL was defined as the duration of time measured in minutes that it took a participant to fall asleep as recorded daily in the participant's sleep diary. SL values over the 14-day active treatment period were averaged for each participant, and average SL was then reported by treatment arm. For participants with missing data, the average of the nights for which TST data were present were used in the analysis.

    Measured: Day 1 to Day 15

  2. Number of Participants Experiencing an Adverse Event (AE) During the 14-day In-treatment Period

    The total number of participants with an AE during the 14-day In-treatment Period was tallied for each treatment arm. An AE was defined as any untoward medical occurrence in a participant or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE could therefore have been any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

    Measured: Day 1 to Day 15

  3. Number of Participants Who Discontinued From Study Treatment Due to an AE During the 14-day In-Treatment Period

    The total number of participants discontinuing from study treatment due to experiencing an AE was tallied for each treatment arm. An AE was defined as any untoward medical occurrence in a participant or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE could therefore have been any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

    Measured: Day 1 to Day 15

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Esmirtazapine 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 2 inclusion and 6 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. 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 10 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?

Average Total Sleep Time (TST) as Recorded Daily in the Sleep Diary During the 14-day In-treatment Period (time frame: Day 1 to Day 15). 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 NCT00482612, 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 3 Oct 2018.
