Key findings

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

    78 of 200 indexed trials (39%) 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 Glioblastoma trials is spread across many organizations.

    National Cancer Institute (NCI) accounts for 10 of 200 trials (5%). 112 distinct sponsors appear on at least one study for this condition label.

  3. Most Glioblastoma trials plan to enrol fewer than 100 people.

    Median target enrolment is 44 among the 200 trials that report a genuine target (sentinel values excluded). 153 of those (76.5%) plan for fewer than 100 participants.

  4. Glioblastoma research is mostly interventional.

    186 interventional and 14 observational studies make up this index (93% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
