Key findings

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

    51 of 274 indexed trials (18.6%) 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 Leukemia trials is spread across many organizations.

    M.D. Anderson Cancer Center accounts for 37 of 274 trials (13.5%). 84 distinct sponsors appear on at least one study for this condition label.

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

    Median target enrolment is 49 among the 234 trials that report a genuine target (sentinel values excluded). 170 of those (72.6%) plan for fewer than 100 participants.

  4. Leukemia research is mostly interventional.

    243 interventional and 31 observational studies make up this index (88.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
