Key findings

What ClinicalTrials.gov does not surface for CBD on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. CBD is recruiting below its size-band peers.

    3 of 9 indexed trials (33.3%) are open to enrollment, against a 46.5% average across 27,806 conditions with fewer than 20 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of CBD trials is spread across many organizations.

    Dana-Farber Cancer Institute accounts for 1 of 9 trials (11.1%). 9 distinct sponsors appear on at least one study for this condition label.

  3. Most CBD trials plan to enrol fewer than 100 people.

    Median target enrolment is 60 among the 9 trials that report a genuine target (sentinel values excluded). 8 of those (88.9%) plan for fewer than 100 participants.

  4. CBD research is mostly interventional.

    8 interventional and 1 observational studies make up this index (88.9% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
