Key findings

What ClinicalTrials.gov does not surface for HIV 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. HIV recruits in line with its size-band peers.

    109 of 304 indexed trials (35.9%) are open to enrollment, against a 37.1% average across 139 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of HIV trials is spread across many organizations.

    National Institute of Allergy and Infectious Diseases (NIAID) accounts for 24 of 304 trials (7.9%). 115 distinct sponsors appear on at least one study for this condition label.

  3. Typical HIV enrolment sits around 100 participants.

    Median target enrolment is 100 among the 304 trials that report a genuine target (sentinel values excluded). 142 of those (46.7%) plan for fewer than 100 participants.

  4. HIV research is mostly interventional.

    252 interventional and 52 observational studies make up this index (82.9% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
