Key findings

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

    46 of 106 indexed trials (43.4%) are open to enrollment, against a 37.1% average across 139 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

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

    Hospital for Special Surgery, New York accounts for 7 of 106 trials (6.6%). 69 distinct sponsors appear on at least one study for this condition label.

  3. Typical Opioid Use enrolment sits around 144 participants.

    Median target enrolment is 144 among the 106 trials that report a genuine target (sentinel values excluded). 38 of those (35.8%) plan for fewer than 100 participants.

  4. Opioid Use research is mostly interventional.

    95 interventional and 11 observational studies make up this index (89.6% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
