Key findings

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

    3 of 8 indexed trials (37.5%) 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. One sponsor concentrates Osteonecrosis research.

    University of California, Davis accounts for 2 of 8 trials (25%). 7 distinct sponsors appear on at least one study for this condition label.

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

    Median target enrolment is 53 among the 8 trials that report a genuine target (sentinel values excluded). 6 of those (75%) plan for fewer than 100 participants.

  4. Osteonecrosis splits between interventional and observational designs.

    5 interventional and 3 observational studies make up this index (62.5% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
