Key findings

What ClinicalTrials.gov does not surface for Pain on its own pages , computed from the registry mirror as of 2026-07-11. Each line carries its own denominator so it can be quoted as it stands.

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

    106 of 377 indexed trials (28.1%) are open to enrollment, against a 37.2% average across 135 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

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

    University of Florida accounts for 9 of 377 trials (2.4%). 214 distinct sponsors appear on at least one study for this condition label.

  3. Typical Pain enrolment sits around 84 participants.

    Median target enrolment is 84 among the 375 trials that report a genuine target (sentinel values excluded). 201 of those (53.6%) plan for fewer than 100 participants.

  4. Pain research is mostly interventional.

    319 interventional and 58 observational studies make up this index (84.6% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
