Key findings

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

    108 of 188 indexed trials (57.4%) 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 Endometrial Cancer trials is spread across many organizations.

    Memorial Sloan Kettering Cancer Center accounts for 17 of 188 trials (9%). 116 distinct sponsors appear on at least one study for this condition label.

  3. Typical Endometrial Cancer enrolment sits around 108 participants.

    Median target enrolment is 108 among the 182 trials that report a genuine target (sentinel values excluded). 85 of those (46.7%) plan for fewer than 100 participants.

  4. Endometrial Cancer research is mostly interventional.

    167 interventional and 21 observational studies make up this index (88.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
