-
Aging is recruiting above its size-band peers.
126 of 263 indexed trials (47.9%) 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.
-
Sponsorship of Aging trials is spread across many organizations.
University of Florida accounts for 14 of 263 trials (5.3%). 132 distinct sponsors appear on at least one study for this condition label.
-
Most Aging trials plan to enrol fewer than 100 people.
Median target enrolment is 66 among the 263 trials that report a genuine target (sentinel values excluded). 166 of those (63.1%) plan for fewer than 100 participants.
