Key findings

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

    9 of 19 indexed trials (47.4%) are open to enrollment, against a 46.5% average across 27,806 conditions with fewer than 20 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. One sponsor concentrates Chronic Spontaneous Urticaria research.

    Novartis Pharmaceuticals accounts for 8 of 19 trials (42.1%). 9 distinct sponsors appear on at least one study for this condition label.

  3. Typical Chronic Spontaneous Urticaria enrolment sits around 350 participants.

    Median target enrolment is 350 among the 19 trials that report a genuine target (sentinel values excluded). 3 of those (15.8%) plan for fewer than 100 participants.

  4. Chronic Spontaneous Urticaria research is mostly interventional.

    14 interventional and 5 observational studies make up this index (73.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
