Key findings

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

    147 of 338 indexed trials (43.5%) 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 Ovarian Cancer trials is spread across many organizations.

    Memorial Sloan Kettering Cancer Center accounts for 31 of 338 trials (9.2%). 186 distinct sponsors appear on at least one study for this condition label.

  3. Typical Ovarian Cancer enrolment sits around 86 participants.

    Median target enrolment is 86 among the 323 trials that report a genuine target (sentinel values excluded). 172 of those (53.3%) plan for fewer than 100 participants.

  4. Ovarian Cancer research is mostly interventional.

    297 interventional and 41 observational studies make up this index (87.9% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
