Key findings

What ClinicalTrials.gov does not surface for Solid Tumors 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. Solid Tumors is recruiting below its size-band peers.

    43 of 127 indexed trials (33.9%) 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 Solid Tumors trials is spread across many organizations.

    M.D. Anderson Cancer Center accounts for 8 of 127 trials (6.3%). 77 distinct sponsors appear on at least one study for this condition label.

  3. Typical Solid Tumors enrolment sits around 70 participants.

    Median target enrolment is 70 among the 126 trials that report a genuine target (sentinel values excluded). 72 of those (57.1%) plan for fewer than 100 participants.

  4. Solid Tumors research is mostly interventional.

    122 interventional and 5 observational studies make up this index (96.1% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
