About this study

Official title: A Randomized, Double-Blind, Single-Dose, 4-Way Crossover Study to Assess the Efficacy and Safety of SM-1 (50-mg Diphenhydramine, 5-mg Delayed-Release Zolpidem, and 0.5-mg Delayed-Release Lorazepam) Versus 2 Comparators (50-mg Diphenhydramine and 5-mg Delayed-Release Zolpidem; 50-mg Diphenhydramine and 0.5-mg Delayed-Release Lorazepam) and Placebo in a 5-Hour Phase Advance Model of Transient Insomnia.

The purpose of this study is to investigate the effectiveness, safety and tolerability of a combination drug product (SM-1) containing diphenhydramine, zolpidem and lorazepam, in adult participants who sometimes have difficulty in falling asleep or staying asleep, but who do not have chronic insomnia. Participants will receive SM-1, or a combination of diphenhydramine and zolpidem, or a combination of diphenhydramine and lorazepam, or placebo during 4 one-night stays at a sleep center.

What is being measured

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

  1. Total Sleep Time (TST)

    TST efficacy of SM-1 versus placebo, combination product diphenhydramine plus zolpidem and combination product diphenhydramine plus lorazepam measured by polysomnography (PSG)-defined total sleep time (TST)

    Measured: 8 hours

Secondary outcomes (9)
  1. Latency to Persistent Sleep (LPS)

    Efficacy of SM-1 versus placebo, combination product diphenhydramine plus zolpidem and combination product diphenhydramine plus lorazepam measured by polysomnography (PSG)-measured sleep induction, the amount of time it takes the subject to fall asleep.

    Measured: 8 hours

  2. Number of Awakenings (NAW)

    NAW efficacy of SM-1 versus placebo, combination product diphenhydramine plus zolpidem and combination product diphenhydramine plus lorazepam measured by polysomnography (PSG)-measured sleep maintenance.

    Measured: 8 hours

  3. Wakefulness After Sleep Onset (WASO)

    WASO efficacy of SM-1 versus placebo, combination product diphenhydramine plus zolpidem and combination product diphenhydramine plus lorazepam measured by polysomnography (PSG)-measured sleep maintenance as the amount of time spent awake after falling asleep.

    Measured: 8 hours

  4. Karolinska Sleepiness Scale (KSS) of Morning Alertness.

    Morning alertness measured by Karolinska Sleepiness Scale (KSS). KSS ranges from 1-9, with higher numbers indicating sleepier and lower numbers more alert.

    Measured: Up to Visit 5

  5. Number Correct on Digit Symbol Substitution Test (DSST)

    Morning alertness measured by DSST. The digit symbol substitution test assesses attention, psychomotor speed, complex scanning, visual tracking, and immediate memory. This test consists of 4 rows each with 25 small blank squares; above each square is a number between 1 and 9. At the top is a 'key,' which pairs each number (1 through 9) with an unfamiliar symbol. The participant has 90 seconds to work as quickly as possible (left to right across the rows) to fill in each blank square with the appropriate symbol based on the number above the square. Results are presented as total number correct; therefore, lower numbers indicate greater impairment. Scores on the DSST range from 0-93

    Measured: Up to Visit 5

  6. Subjective Total Sleep Time (sTST)

    Subject reported TST from Post-Sleep Questionnaire (PSQ).

    Measured: Up to 22 days.

  7. Subjective Sleep Onset Latency (sSOL)

    Subject reported SOL, the amount of time the subject felt it took to fall asleep, from Post-Sleep Questionnaire (PSQ).

    Measured: Up to 22 days.

  8. Subjective Number of Awakenings (sNAW)

    Subject reported NAW from Post-Sleep Questionnaire (PSQ).

    Measured: Up to 22 days.

  9. Number of Participants According to Sleep Quality

    Subject reported sleep quality, how well the subject felt he or she slept, from Post-Sleep Questionnaire (PSQ).

    Measured: Up to 22 days.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SM-1, D+Z and D+L in people with Transient Insomnia, run by Sequential Medicine Ltd 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 10 inclusion and 22 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 5 Jun 2019. 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 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 5 Jun 2019). 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?

Total Sleep Time (TST) (time frame: 8 hours). 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 5 Jun 2019.
