Key findings

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

    31 of 119 indexed trials (26.1%) 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 Weight Loss trials is spread across many organizations.

    Drexel University accounts for 4 of 119 trials (3.4%). 85 distinct sponsors appear on at least one study for this condition label.

  3. Typical Weight Loss enrolment sits around 79 participants.

    Median target enrolment is 79 among the 117 trials that report a genuine target (sentinel values excluded). 66 of those (56.4%) plan for fewer than 100 participants.

  4. Weight Loss research is mostly interventional.

    107 interventional and 12 observational studies make up this index (89.9% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
