Key findings

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

    10 of 16 indexed trials (62.5%) are open to enrollment, against a 46.5% average across 27,806 conditions with fewer than 20 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

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

    Immatics US accounts for 2 of 16 trials (12.5%). 15 distinct sponsors appear on at least one study for this condition label.

  3. Most Refractory Cancer trials plan to enrol fewer than 100 people.

    Median target enrolment is 77 among the 16 trials that report a genuine target (sentinel values excluded). 11 of those (68.8%) plan for fewer than 100 participants.

  4. Refractory Cancer research is mostly interventional.
