Key findings

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

    139 of 302 indexed trials (46%) 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 Chronic Pain trials is spread across many organizations.

    VA Office of Research and Development accounts for 16 of 302 trials (5.3%). 155 distinct sponsors appear on at least one study for this condition label.

  3. Typical Chronic Pain enrolment sits around 80 participants.

    Median target enrolment is 80 among the 302 trials that report a genuine target (sentinel values excluded). 164 of those (54.3%) plan for fewer than 100 participants.

  4. Chronic Pain research is mostly interventional.

    260 interventional and 42 observational studies make up this index (86.1% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
