About this study

Official title: A Phase 1 Study to Assess the Safety and Pharmacokinetics of Novel Cannabidiol (CBD) Soft-gel Capsule Formulation (NW300EMCBD) in Healthy Subjects

The purpose of this study is to test a new formulation of cannabidiol (CBD) to see how it is processed in the body and how safe it is for healthy volunteers. CBD is a compound found in the cannabis plant that has shown potential to help treat various medical and mental health conditions. While there is already an approved CBD-based drug that is used for epilepsy in the UK, called Epidyolex, most CBD formulations have poor absorption when taken orally, reducing their effectiveness and often requiring higher doses.

NW PharmaTech has developed a new CBD formulation aimed at improving absorption and processing by the body. This study will assess the absorption, safety, and tolerability of two different doses (600 mg and 900 mg) of the new formulation and will compare them with Epidyolex (dosed as per approved label).

All participants will receive each of the following three dosing regimens in a randomised order across three separate experimental periods, with each period separated by a 25 day washout period, which ensures that the drug from one dosing regimen is fully cleared from your body before the next dosing regimen begins.

Regimen A: 600 mg of the new CBD formulation (NW300EMCBD) administered orally Regimen B: 900 mg of the new CBD formulation (NW300EMCBD) administered orally Regimen C: 25 mg/kg Epidyolex solution (2 x 12.5 mg/kg doses separated by 12 hours) administered orally In total, participants will complete three dosing visits (one per experimental period), each spaced 25 days apart. The study will evaluate the pharmacokinetics (PK) of the formulations, which refers to how the body absorbs, distributes, metabolizes, and eliminates the drugs.

  18. Number of participants with suicidal ideation and/or behavior as assessed by Columbia-Suicide Severity Rating Scale (C-SSRS)

    The Columbia-Suicide Severity Rating Scale (C-SSRS) is a clinician administered assessment tool that evaluates suicidal ideation and behavior. Number of participants that have an affirmative response provided to the 5 items for suicidal ideation (1. Wish to be dead, 2. Non-specific active suicidal thoughts, 3. Active suicidal ideation with any methods (not plan) without intent to act, 4. Active suicidal ideation with some intent to act, without specific plan, 5. Active suicidal ideation with specific plan and intent) and/or to the 6 items for suicidal behavior (1. Actual attempt, 2. Interrupted attempt, 3. Aborted attempt, 4. Preparatory acts or behavior, 5.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CBD soft-gel capsules 600 mg, CBD soft-gel capsules 900 mg and Epidyolex in people with PK in Healthy Volunteers, run by NW PharmaTech Ltd at 1 site in United Kingdom.

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 9 inclusion and 25 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 2 Feb 2026. 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 United Kingdom. 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?

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?

CBD plasma concentration (time frame: Pre-dose up to 192 hours post dose). 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 2 Feb 2026.
