Key findings

What ClinicalTrials.gov does not surface for Loneliness 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. Loneliness is recruiting below its size-band peers.

    11 of 36 indexed trials (30.6%) 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 Loneliness trials is spread across many organizations.

    University of Rochester accounts for 5 of 36 trials (13.9%). 28 distinct sponsors appear on at least one study for this condition label.

  3. Typical Loneliness enrolment sits around 96 participants.

    Median target enrolment is 96 among the 36 trials that report a genuine target (sentinel values excluded). 19 of those (52.8%) plan for fewer than 100 participants.

  4. Loneliness research is mostly interventional.

    33 interventional and 3 observational studies make up this index (91.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
