Key findings

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

    76 of 318 indexed trials (23.9%) 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 Schizophrenia trials is spread across many organizations.

    University of Maryland, Baltimore accounts for 14 of 318 trials (4.4%). 129 distinct sponsors appear on at least one study for this condition label.

  3. Typical Schizophrenia enrolment sits around 83 participants.

    Median target enrolment is 83 among the 316 trials that report a genuine target (sentinel values excluded). 169 of those (53.5%) plan for fewer than 100 participants.

  4. Schizophrenia research is mostly interventional.

    290 interventional and 28 observational studies make up this index (91.2% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
