Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 45 years
- All sexes
- Healthy volunteers accepted
- Adult
Inclusion criteria i. Healthy volunteers. Defined as healthy on the basis of a clinical history, physical examination, ECG, vital signs, and laboratory tests of blood and urine.
ii. Age 18-45 iii. Agreeing to fast 15 hours; 10pm-1pm on dosing days iv. Capable of giving informed consent v. Written informed consent from participant
Exclusion criteria i. Clinically relevant medical history, physical findings, ECG, or laboratory values at the pre-trial screening assessment that could interfere with the objectives of the trial or the safety of the participant.
ii. Presence of acute or chronic illness or history of chronic illness sufficient to invalidate the volunteer's participation in the trial or make it unnecessarily hazardous.

About this study
Cannabidiol (CBD) has been approved as a treatment for rare childhood epilepsies and could be an effective treatment for psychotic disorders, anxiety disorders and addictions. It is available as an oral liquid and as standard oral capsules.
The bioavailability of oral cannabidiol is poor (only around 5-10% is absorbed), particularly in the fasted state. With food, its absorption is much higher. In one study, a high-fat breakfast increased the maximum plasma concentration by 4-5 times. As a result of this food effect, when prescribing standard oral formulations of CBD, clinicians should provide advice on dosing the drug according to mealtimes, otherwise, there may be an increased risk of side effects or limited effectiveness.

One way to reduce the food effect and improve bioavailability is to use lipid excipients. In the present study, the investigators will evaluate CBD at the dose that is effective in patients with chronic psychosis (1000mg). The novel formulation will use lipids that are all EU pharmacopoeia approved and have been used in medicinal products before.
The study aims to assess whether a novel lipid formulation can increase the bioavailability of oral CBD in the fasting state.

What is being measured
The primary outcome is the main question the study is designed to answer.
Total Drug Exposure. (Area Under the Curve to Infinity [AUC(Inf)]
Difference in AUC(inf) for a single dose of oral CBD between the novel and standard formulations in the fasting state.
Measured: 0 - 48 hours
Secondary outcomes (5)
Cmax
Maximum plasma concentration
Measured: 0 - 48 hours
Tmax
Time after administration of drug when maximum plasma concentration is reached

Half-life
Measured: 0 - 48 hours
48 Hour Drug Exposure (AUC0-48)
Area under the concentration-time curve from time zero to 48hours
Measured: 0 - 48 hours
Gastrointestinal Symptom Rating Scale (GSRS) - Total Score
The GSRS was used to assess gastrointestinal symptoms over the past 24 hours only. It is a 15-item rating scale, where each item is assessed with a 7-point Likert scale, scored from 1 to 7, and with higher scores indicating more severe symptoms. The total score is the mean score across items (minimum score=1; maximum sore=7).
Measured: The scale will be used pre-dose and at 24 and 48 hours post dose.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Cannabidiol (CBD) has been approved as a treatment for rare childhood epilepsies and could be an effective treatment for psychotic disorders, anxiety disorders and addictions. It is available as an oral liquid and as standard oral capsules.
The bioavailability of oral cannabidiol is poor (only around 5-10% is absorbed), particularly in the fasted state. With food, its absorption is much higher. In one study, a high-fat breakfast increased the maximum plasma concentration by 4-5 times. As a result of this food effect, when prescribing standard oral formulations of CBD, clinicians should provide advice on dosing the drug according to mealtimes, otherwise, there may be an increased risk of side effects or limited effectiveness.
One way to reduce the food effect and improve bioavailability is to use lipid excipients. In the present study, the investigators will evaluate CBD at the dose that is effective in patients with chronic psychosis (1000mg). The novel formulation will use lipids that are all EU pharmacopoeia approved and have been used in medicinal products before.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Standard formulation and Novel formulation in people with Absorption; Chemicals, run by King's College London 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?
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 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?
Yes. Results are posted in the registry (first posted 6 Feb 2024). 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 Drug Exposure. (Area Under the Curve to Infinity [AUC(Inf)] (time frame: 0 - 48 hours). 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 NCT05032807, 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 6 Feb 2024.
