Key findings

What ClinicalTrials.gov does not surface for Cancer on its own pages , computed from the registry mirror as of 2026-07-11. Each line carries its own denominator so it can be quoted as it stands.

  1. Cancer is recruiting above its size-band peers.

    279 of 621 indexed trials (44.9%) are open to enrollment, against a 37.2% average across 135 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

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

    M.D. Anderson Cancer Center accounts for 31 of 621 trials (5%). 270 distinct sponsors appear on at least one study for this condition label.

  3. Typical Cancer enrolment sits around 108 participants.

    Median target enrolment is 108 among the 616 trials that report a genuine target (sentinel values excluded). 287 of those (46.6%) plan for fewer than 100 participants.

  4. Cancer research is mostly interventional.

    462 interventional and 159 observational studies make up this index (74.4% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
