What is being measured

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

  1. Part A: Number of Participants With Treatment Emergent Adverse Events (AEs) and Treatment Emergent Serious Adverse Events (SAEs)

    Measured: Baseline up to Day 11

  2. Part A: Number of Participants With Markedly Abnormal Laboratory Parameter Values

    Measured: Baseline up to Day 6

  3. Part A: Number of Participants With Significant Change From Baseline in Vital Sign Values

    Measured: Baseline up to Day 11

  4. Part A: Number of Participants With Clinically Significant Change From Baseline in Electrocardiogram (ECG) Parameter Values

    Measured: Baseline up to Day 11

  5. Part A: Number of Participants With Any Suicidality Assessed Using Columbia-Suicide Severity Rating Scale (C-SSRS)

    The C-SSRS (mapped to Columbia Classification Algorithm of Suicide Assessment [C-CASA]) is an interview-based rating scale to systematically assess any suicidality, any suicidal behavior, any suicidal ideation. Any suicidality: emergence of any suicidal ideation or suicidal behavior. Any suicidal behavior: when response is "yes" for any these questions- actual attempt to suicide, engaged in non-suicidal self-injurious behavior, interrupted attempt, aborted attempt, preparatory acts. Any suicidal ideation: when response is "yes" for any of these questions- wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent to suicide. Number of Participants with any suicidality has been reported for this outcome measure.

    Measured: Baseline, Day 11

  6. Part B: Change From Baseline in Latency to Persistent Sleep (LPS) Assessed Using Polysomnography (PSG) Measurement at Day 1

    LPS was the duration of time in minutes from lights off to the first 30 seconds of recording (epoch) of 20 consecutive epochs of non-wakefulness as measured by PSG.

    Measured: Baseline, Day 1

  7. Part B: Change From Baseline in Total Sleep Time (TST) Assessed Using PSG at Day 1

    TST was the duration in minutes including rapid eye movement (REM) sleep plus non-rapid eye movement (NREM) sleep during the time spent in bed.

    Measured: Baseline, Day 1

  8. Part B: Change From Baseline in Sleep Efficiency Assessed Using PSG at Day 1

    Sleep efficiency was defined as the TST divided by the time in bed (minutes) multiplied by 100. TST was the duration in minutes including REM sleep plus NREM sleep during the time spent in bed.

    Measured: Baseline, Day 1

  9. Part B: Change From Baseline in Wake After Sleep Onset (WASO) Assessed Using PSG at Day 1

    WASO was defined as the duration (in minutes) of wakefulness from onset of persistent sleep to lights-on.

    Measured: Baseline, Day 1

  10. Part B: Change From Baseline in Number of Awakenings After Persistent Sleep (NAW) Assessed Using PSG at Day 1

    Number of awakenings was determined from LPS to lights-on. LPS was the duration of time measured from lights off to the first 30 seconds of PSG measurement recording (epoch) of 20 consecutive epochs of non-wake. An awakening was defined as a PSG recording of at least two consecutive wake epochs.

    Measured: Baseline, Day 1

  11. Part B: Change From Baseline in Percentage of Each Sleep Stage Duration Assessed Using PSG at Day 1

    Sleep stages included NREM sleep and REM (dreaming) sleep. Non-REM sleep is comprised of the sum of Stage N1 (light sleep), N2 (also fairly light, with sudden increases in brain wave frequency known as sleep spindles) and N3 or slow wave sleep (deep sleep). Sleep was staged in sequential 30-second epochs.

    Measured: Baseline, Day 1

  12. Part B: Change From Baseline in Duration (in Minutes) of Each Sleep Stage Assessed Using PSG at Day 1

    Sleep stages included NREM sleep and REM (dreaming) sleep. Non-REM sleep is comprised of the sum of Stage N1 (light sleep), N2 (also fairly light, with sudden increases in brain wave frequency known as sleep spindles) and N3 or slow wave sleep (deep sleep). Sleep was staged in sequential 30-second epochs.

    Measured: Baseline, Day 1

  13. Part B: Change From Baseline in Mean Total Number of Shift in Sleep Stages Assessed Using PSG at Day 1

    Sleep stages included NREM sleep and REM (dreaming) sleep. Non-REM sleep is comprised of the sum of Stage N1 (light sleep), N2 (also fairly light, with sudden increases in brain wave frequency known as sleep spindles) and N3 or slow wave sleep (deep sleep). Sleep was staged in sequential 30-second epochs.

    Measured: Baseline, Day 1

  14. Part B: Change From Day 1 in Waketime Questionnaire Parameters: How Long Did You Sleep Last Night at Day 6

    Participants were asked to answer the following question using Waketime Questionnaire: How long did you sleep last night, number of awakening after falling asleep, time to fall asleep last night, time spent awake after falling asleep, rate quality of your sleep (using Likert scale, ranged from 0 = very sound or restful, to 4 = very restless where lower score indicates better outcome).

  19. Part B: Change From Day 1 (Pre-dose) in Digit Symbol Substitution Test (DSST) Score at Day 6

    DSST is a cognitive test designed to assess psychomotor speed of performance requiring visual perception, spatial decision-making, and motor skills. It consists of 133 digits and requires the participant to substitute each digit with a simple symbol in a 90-second period. Each correct symbol is counted, and the total score ranges from 0 (less than cognitive functioning) to 133 (greater than cognitive functioning) as a description of DSST. An increase in score represents an improvement in an integrated measure of cognitive function.

    Measured: Day 1 (Pre-dose), Day 6

  20. Part B: Change From Day 1 (Pre-dose) in Number of Lapses of Greater Than (>) 500- Milliseconds (Msec) Assessed by Psychomotor Vigilance Test (PVT) at Day 6

    PVT, a computer-based test, is a chronometric measure of an individual's reaction to specified small changes in a labile environment. Participants were instructed to respond to a digital signal on a computer terminal by pressing a key. Errors of omission and commission are recorded. When a participant did not respond to the PVT signal within 500 msec, it was termed a lapse. The higher the number of lapses the greater the impairment.

    Measured: Day 1 (Pre-dose), Day 6

  21. Part B: Change From Day 1 (Pre-dose) in Score on Karolinska Sleepiness Scale (KSS) at Day 6

    KSS is a 9-point scale, on which the participant has to mark his or her sleepiness during the previous 10 minutes. The scale ranges from 1, which indicates "extremely alert", to 9, which indicates "extremely sleepy, can't stay awake". Higher numbers indicating sleepier and lower numbers more alert.

    Measured: Day 1 (Pre-dose), Day 6

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing E2006 1.0 mg, E2006 2.5 mg and E2006 5.0 mg in people with Insomnia, run by Eisai Inc. at 2 sites in United States.

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 11 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 18 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 18 Jan 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?

Part A: Number of Participants With Treatment Emergent Adverse Events (AEs) and Treatment Emergent Serious Adverse Events (SAEs) (time frame: Baseline up to Day 11). The study lists 21 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 18 Jan 2020.
