Key findings

What ClinicalTrials.gov does not surface for Alzheimers Disease on its own pages , computed from the registry mirror as of 2026-07-11. Each line carries its own denominator so it can be quoted as it stands.

  1. Alzheimers Disease is recruiting below its size-band peers.

    30 of 145 indexed trials (20.7%) are open to enrollment, against a 37.2% average across 135 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Alzheimers Disease trials is spread across many organizations.

    Eli Lilly and Company accounts for 8 of 145 trials (5.5%). 86 distinct sponsors appear on at least one study for this condition label.

  3. Typical Alzheimers Disease enrolment sits around 107 participants.

    Median target enrolment is 107 among the 143 trials that report a genuine target (sentinel values excluded). 66 of those (46.2%) plan for fewer than 100 participants.

  4. Alzheimers Disease research is mostly interventional.

    119 interventional and 26 observational studies make up this index (82.1% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
