Key findings

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

    34 of 72 indexed trials (47.2%) 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 Crohn Disease trials is spread across many organizations.

    Massachusetts General Hospital accounts for 6 of 72 trials (8.3%). 51 distinct sponsors appear on at least one study for this condition label.

  3. Typical Crohn Disease enrolment sits around 84 participants.

    Median target enrolment is 84 among the 72 trials that report a genuine target (sentinel values excluded). 38 of those (52.8%) plan for fewer than 100 participants.

  4. Crohn Disease research is mostly interventional.

    58 interventional and 14 observational studies make up this index (80.6% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
