Key findings

What ClinicalTrials.gov does not surface for Type 1 Diabetes Mellitus 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. Type 1 Diabetes Mellitus is recruiting below its size-band peers.

    25 of 113 indexed trials (22.1%) 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 Type 1 Diabetes Mellitus trials is spread across many organizations.

    University of Virginia accounts for 9 of 113 trials (8%). 67 distinct sponsors appear on at least one study for this condition label.

  3. Most Type 1 Diabetes Mellitus trials plan to enrol fewer than 100 people.

    Median target enrolment is 48 among the 113 trials that report a genuine target (sentinel values excluded). 80 of those (70.8%) plan for fewer than 100 participants.

  4. Type 1 Diabetes Mellitus research is mostly interventional.

    95 interventional and 18 observational studies make up this index (84.1% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
