Key findings

What ClinicalTrials.gov does not surface for Parkinsons Disease (PD) 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. Parkinsons Disease (PD) is recruiting above its size-band peers.

    13 of 20 indexed trials (65%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. One sponsor concentrates Parkinsons Disease (PD) research.

    AbbVie accounts for 5 of 20 trials (25%). 15 distinct sponsors appear on at least one study for this condition label.

  3. Most Parkinsons Disease (PD) trials plan to enrol fewer than 100 people.

    Median target enrolment is 77 among the 20 trials that report a genuine target (sentinel values excluded). 13 of those (65%) plan for fewer than 100 participants.

  4. Parkinsons Disease (PD) research is mostly interventional.

    18 interventional and 2 observational studies make up this index (90% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
