Key findings

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

    70 of 378 indexed trials (18.5%) 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 Asthma trials is spread across many organizations.

    GlaxoSmithKline accounts for 24 of 378 trials (6.3%). 161 distinct sponsors appear on at least one study for this condition label.

  3. Typical Asthma enrolment sits around 144 participants.

    Median target enrolment is 144 among the 375 trials that report a genuine target (sentinel values excluded). 160 of those (42.7%) plan for fewer than 100 participants.

  4. Asthma research is mostly interventional.

    298 interventional and 80 observational studies make up this index (78.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
