Key findings

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

    37 of 106 indexed trials (34.9%) 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 Crohn's Disease trials is spread across many organizations.

    Takeda accounts for 13 of 106 trials (12.3%). 52 distinct sponsors appear on at least one study for this condition label.

  3. Typical Crohn's Disease enrolment sits around 196 participants.

    Median target enrolment is 196 among the 106 trials that report a genuine target (sentinel values excluded). 36 of those (34%) plan for fewer than 100 participants.

  4. Crohn's Disease research is mostly interventional.

    90 interventional and 16 observational studies make up this index (84.9% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
