Key findings

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

    12 of 22 indexed trials (54.5%) 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 Anhedonia trials is spread across many organizations.

    Mclean Hospital accounts for 3 of 22 trials (13.6%). 14 distinct sponsors appear on at least one study for this condition label.

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

    Median target enrolment is 78 among the 22 trials that report a genuine target (sentinel values excluded). 14 of those (63.6%) plan for fewer than 100 participants.

  4. Anhedonia research is mostly interventional.

    18 interventional and 4 observational studies make up this index (81.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
