Key findings

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

    155 of 312 indexed trials (49.7%) 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 Alzheimer Disease trials is spread across many organizations.

    Eli Lilly and Company accounts for 13 of 312 trials (4.2%). 178 distinct sponsors appear on at least one study for this condition label.

  3. Typical Alzheimer Disease enrolment sits around 100 participants.

    Median target enrolment is 100 among the 307 trials that report a genuine target (sentinel values excluded). 151 of those (49.2%) plan for fewer than 100 participants.

  4. Alzheimer Disease research is mostly interventional.

    255 interventional and 57 observational studies make up this index (81.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
