Key findings

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

    78 of 164 indexed trials (47.6%) 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 Epilepsy trials is spread across many organizations.

    National Institute of Neurological Disorders and Stroke (NINDS) accounts for 9 of 164 trials (5.5%). 95 distinct sponsors appear on at least one study for this condition label.

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

    Median target enrolment is 60 among the 161 trials that report a genuine target (sentinel values excluded). 103 of those (64%) plan for fewer than 100 participants.

  4. Epilepsy research is mostly interventional.

    120 interventional and 44 observational studies make up this index (73.2% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
