Key findings

What ClinicalTrials.gov does not surface for Healthy 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. Healthy is recruiting below its size-band peers.

    225 of 1,096 indexed trials (20.5%) 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 Healthy trials is spread across many organizations.

    Eli Lilly and Company accounts for 55 of 1,096 trials (5%). 429 distinct sponsors appear on at least one study for this condition label.

  3. Most Healthy trials plan to enrol fewer than 100 people.

    Median target enrolment is 40 among the 1,091 trials that report a genuine target (sentinel values excluded). 851 of those (78%) plan for fewer than 100 participants.

  4. Healthy research is mostly interventional.

    905 interventional and 191 observational studies make up this index (82.6% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
