About this study

Official title: A Randomised, Double-blind, Placebo-controlled, Single-dose, Crossover, Pilot Study Investigating the Effects of Cannabinol (CBN) 30 mg and 300 mg on Sleep Architecture and Next-day Function in Insomnia Disorder

This study aims to investigate the acute effects of cannabinol (CBN) 30 mg and 300 mg, versus placebo, on sleep architecture and next-day functioning in adults aged 25-65 years with chronic insomnia disorder.

Read the detailed description

This is a randomised, double-blind, placebo-controlled, three-arm, crossover, single-centre, proof-of-concept study in twenty participants with chronic insomnia disorder (as per clinician diagnosis and Insomnia Severity Index [ISI] Score ≥15). Across three overnight treatment sessions, participants will receive single dose oral liquid 30 mg cannabinol (CBN), 300 mg CBN, and matched placebo. Participants will undergo overnight sleep assessment using in-laboratory polysomnography (PSG) to examine CBN-related changes to sleep parameters; and various objective and subjective measures of sleep and next-day neurobehavioral function. Each treatment session will be separated by the two-week washout period.

What participants receive

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

  • 30 mg Cannabinol (CBN)Drug

    Also called ECS 310 (1.5%)

    Participants will receive a 2 mL oral dose of 'ECS 310' (1.5%), an oral formulation of CBN (15 mg/mL) suspended in medium chain triglycerides (MCT) oil.

  • 300 mg Cannabinol (CBN)Drug

    Also called ECS 310 (15%)

    Participants will receive a 2 mL oral dose of 'ECS 310' (15%), an oral formulation of CBN (150 mg/mL) suspended in medium chain triglycerides (MCT) oil.

  • PlaceboDrug

    Participants will receive a 2 mL oral dose of placebo. Placebo contains the same excipient, medium chain triglycerides (MCT) oil, as the investigational products but does not contain cannabinoids.

What is being measured

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

  1. Wake After Sleep Onset (WASO)

    WASO measured in minutes using in-laboratory overnight polysomnography, from the first epoch after lights out until the last epoch, scored as any stage of sleep by an experienced polysomnographic technician in accordance with American Academy of Sleep Medicine (AASM) 2020 Sleep Scoring criteria (Version 2.6). Comparisons between each CBN dose versus placebo.

    Measured: Night 1

Secondary outcomes (3)
  1. Traditional sleep staging

    Proportion of the sleep opportunity scored at the 5 stages (wake, and N1, N2, N3, and REM sleep) between lights out and lights on, measured using overnight in-laboratory polysomnography, scored by a polysomnography technician in accordance with AASM Sleep Scoring criteria. Comparisons between each CBN dose versus placebo.

    Measured: Night 1

  2. Sleep Onset Latency (SOL)

    SOL measured in minutes using in-laboratory polysomnography, calculated from the time of lights out to the first sleep epoch as scored by a polysomnographic technician in accordance with AASM Sleep Scoring criteria. Comparisons between each CBN dose versus placebo.

    Measured: Night 1

  3. Absolute Electroencephalographic (EEG) Power During Non-Rapid Eye Movement (NREM) Sleep.

    Spectral power of delta (1-4.5 Hz), theta (4.5-8 Hz), alpha (8-12 Hz), sigma (12-15 Hz), beta (15-25 Hz), and gamma (25-40 Hz) frequency ranges between treatment arms. Power spectral analysis will be applied to EEG signals from polysomnography after artefacts are detected and removed. Comparisons between each CBN dose versus placebo.

    Measured: Night 1

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing 30 mg Cannabinol (CBN) and 300 mg Cannabinol (CBN) in people with Insomnia Disorder, run by Woolcock Institute of Medical Research at 1 site in Australia.

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 6 inclusion and 23 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 6 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. 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. 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 combined 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.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Wake After Sleep Onset (WASO) (time frame: Night 1). 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 NCT05344170, which also lists 2 linked publications.

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 6 Feb 2024.
