Key findings

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

    25 of 43 indexed trials (58.1%) 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. Sponsorship of Aphasia trials is spread across many organizations.

    Medical College of Wisconsin accounts for 5 of 43 trials (11.6%). 28 distinct sponsors appear on at least one study for this condition label.

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

    Median target enrolment is 60 among the 43 trials that report a genuine target (sentinel values excluded). 29 of those (67.4%) plan for fewer than 100 participants.

  4. Aphasia research is mostly interventional.

    39 interventional and 4 observational studies make up this index (90.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
