Key findings

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

    6 of 14 indexed trials (42.9%) 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. One sponsor concentrates Neutropenia research.

    National Cancer Institute (NCI) accounts for 3 of 14 trials (21.4%). 11 distinct sponsors appear on at least one study for this condition label.

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

    Median target enrolment is 50 among the 13 trials that report a genuine target (sentinel values excluded). 10 of those (76.9%) plan for fewer than 100 participants.

  4. Neutropenia research is mostly interventional.

    12 interventional and 2 observational studies make up this index (85.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
