Key findings

What ClinicalTrials.gov does not surface for Obesity on its own pages , computed from the registry mirror as of 2026-07-11. Each line carries its own denominator so it can be quoted as it stands.

  1. Obesity is recruiting below its size-band peers.

    306 of 1,057 indexed trials (28.9%) are open to enrollment, against a 37.2% average across 135 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Obesity trials is spread across many organizations.

    Eli Lilly and Company accounts for 48 of 1,057 trials (4.5%). 314 distinct sponsors appear on at least one study for this condition label.

  3. Typical Obesity enrolment sits around 90 participants.

    Median target enrolment is 90 among the 1,054 trials that report a genuine target (sentinel values excluded). 555 of those (52.7%) plan for fewer than 100 participants.

  4. Obesity research is mostly interventional.

    894 interventional and 163 observational studies make up this index (84.6% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
