Key findings

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

    18 of 42 indexed trials (42.9%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Epithelial Ovarian Cancer trials is spread across many organizations.

    Imunon accounts for 3 of 42 trials (7.1%). 35 distinct sponsors appear on at least one study for this condition label.

  3. Typical Epithelial Ovarian Cancer enrolment sits around 90 participants.

    Median target enrolment is 90 among the 42 trials that report a genuine target (sentinel values excluded). 23 of those (54.8%) plan for fewer than 100 participants.

  4. Epithelial Ovarian Cancer research is mostly interventional.

    42 interventional and 0 observational studies make up this index (100% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
