Key findings

What ClinicalTrials.gov does not surface for Substance Use 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. Substance Use is recruiting above its size-band peers.

    42 of 89 indexed trials (47.2%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Substance Use trials is spread across many organizations.

    Johns Hopkins Bloomberg School of Public Health accounts for 6 of 89 trials (6.7%). 56 distinct sponsors appear on at least one study for this condition label.

  3. Typical Substance Use enrolment sits around 224 participants.

    Median target enrolment is 224 among the 89 trials that report a genuine target (sentinel values excluded). 26 of those (29.2%) plan for fewer than 100 participants.

  4. Substance Use research is mostly interventional.

    84 interventional and 5 observational studies make up this index (94.4% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
