Key findings

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

    245 of 687 indexed trials (35.7%) 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 Depression trials is spread across many organizations.

    Massachusetts General Hospital accounts for 29 of 687 trials (4.2%). 231 distinct sponsors appear on at least one study for this condition label.

  3. Typical Depression enrolment sits around 100 participants.

    Median target enrolment is 100 among the 680 trials that report a genuine target (sentinel values excluded). 331 of those (48.7%) plan for fewer than 100 participants.

  4. Depression research is mostly interventional.

    618 interventional and 69 observational studies make up this index (90% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
