Key findings

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

    6 of 21 indexed trials (28.6%) 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 Primary Peritoneal Carcinoma trials is spread across many organizations.

    Gynecologic Oncology Group accounts for 2 of 21 trials (9.5%). 19 distinct sponsors appear on at least one study for this condition label.

  3. Typical Primary Peritoneal Carcinoma enrolment sits around 70 participants.

    Median target enrolment is 70 among the 21 trials that report a genuine target (sentinel values excluded). 12 of those (57.1%) plan for fewer than 100 participants.

  4. Primary Peritoneal Carcinoma research is mostly interventional.

    17 interventional and 4 observational studies make up this index (81% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
