Key findings

What ClinicalTrials.gov does not surface for Prostate 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. Prostate Cancer recruits in line with its size-band peers.

    275 of 749 indexed trials (36.7%) 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 Prostate Cancer trials is spread across many organizations.

    Memorial Sloan Kettering Cancer Center accounts for 53 of 749 trials (7.1%). 283 distinct sponsors appear on at least one study for this condition label.

  3. Typical Prostate Cancer enrolment sits around 82 participants.

    Median target enrolment is 82 among the 736 trials that report a genuine target (sentinel values excluded). 389 of those (52.9%) plan for fewer than 100 participants.

  4. Prostate Cancer research is mostly interventional.

    628 interventional and 121 observational studies make up this index (83.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
