Study summary

CBD may affect metabolic control and energy intake. However, there is currently little data regarding these specific outcomes in humans. Therefore, this study will investigate whether a single 300 mg dose of CBD can improve metabolic control following a meal and/or reduce energy intake at a subsequent meal. Healthy, adult volunteers will complete two conditions in a crossover design, comparing outcomes following both CBD and placebo supplementation.

What researchers measure

Primary outcomes

  1. Energy intake

    Self-selected energy intake at an ad libitum mixed meal

    Time frame: 3 hours

  3. Postprandial Triglyceridaemia

    Plasma triglyceride response to a mixed meal (plasma triglyceride concentrations and area under curve)

    Time frame: 3 hours

Secondary outcomes

  1. Postprandial Insulinaemia

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2021 to primary completion in Apr 2022, 7 months.

Of 100 non-industry interventional studies with no phase under Glucose Metabolism Disorders, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 41. This study's 7 months is below that.

Counting every sponsor, half of 110 studies reached it within 19 months; a quarter within 8 and three quarters within 41.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 6, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
