Key findings

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

    37 of 199 indexed trials (18.6%) 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 Rheumatoid Arthritis trials is spread across many organizations.

    Zimmer Biomet accounts for 13 of 199 trials (6.5%). 114 distinct sponsors appear on at least one study for this condition label.

  3. Typical Rheumatoid Arthritis enrolment sits around 154 participants.

    Median target enrolment is 154 among the 198 trials that report a genuine target (sentinel values excluded). 78 of those (39.4%) plan for fewer than 100 participants.

  4. Rheumatoid Arthritis research is mostly interventional.

    154 interventional and 45 observational studies make up this index (77.4% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
