Key findings

What ClinicalTrials.gov does not surface for Autism Spectrum Disorder 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. Autism Spectrum Disorder is recruiting above its size-band peers.

    112 of 225 indexed trials (49.8%) 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 Autism Spectrum Disorder trials is spread across many organizations.

    Stanford University accounts for 19 of 225 trials (8.4%). 113 distinct sponsors appear on at least one study for this condition label.

  3. Most Autism Spectrum Disorder trials plan to enrol fewer than 100 people.

    Median target enrolment is 67 among the 225 trials that report a genuine target (sentinel values excluded). 147 of those (65.3%) plan for fewer than 100 participants.

  4. Autism Spectrum Disorder research is mostly interventional.

    195 interventional and 30 observational studies make up this index (86.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
