Key findings

What ClinicalTrials.gov does not surface for Ulcerative Colitis 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. Ulcerative Colitis recruits in line with its size-band peers.

    45 of 123 indexed trials (36.6%) 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 Ulcerative Colitis trials is spread across many organizations.

    Eli Lilly and Company accounts for 9 of 123 trials (7.3%). 72 distinct sponsors appear on at least one study for this condition label.

  3. Typical Ulcerative Colitis enrolment sits around 118 participants.

    Median target enrolment is 118 among the 123 trials that report a genuine target (sentinel values excluded). 56 of those (45.5%) plan for fewer than 100 participants.

  4. Ulcerative Colitis research is mostly interventional.

    103 interventional and 20 observational studies make up this index (83.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
