Key findings

What ClinicalTrials.gov does not surface for HIV Infections on its own pages , computed from the registry mirror as of 2026-07-11. Each line carries its own denominator so it can be quoted as it stands.

  1. HIV Infections is recruiting below its size-band peers.

    56 of 615 indexed trials (9.1%) are open to enrollment, against a 37.2% average across 135 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. One sponsor concentrates HIV Infections research.

    National Institute of Allergy and Infectious Diseases (NIAID) accounts for 195 of 615 trials (31.7%). 173 distinct sponsors appear on at least one study for this condition label.

  3. Typical HIV Infections enrolment sits around 100 participants.

    Median target enrolment is 100 among the 543 trials that report a genuine target (sentinel values excluded). 267 of those (49.2%) plan for fewer than 100 participants.

  4. HIV Infections research is mostly interventional.

    549 interventional and 66 observational studies make up this index (89.3% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
