Key findings

What ClinicalTrials.gov does not surface for Arthritis 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. Arthritis is recruiting below its size-band peers.

    15 of 49 indexed trials (30.6%) 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 Arthritis trials is spread across many organizations.

    National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) accounts for 4 of 49 trials (8.2%). 37 distinct sponsors appear on at least one study for this condition label.

  3. Typical Arthritis enrolment sits around 154 participants.

    Median target enrolment is 154 among the 49 trials that report a genuine target (sentinel values excluded). 21 of those (42.9%) plan for fewer than 100 participants.

  4. Arthritis research is mostly interventional.

    36 interventional and 13 observational studies make up this index (73.5% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
