Key findings

What ClinicalTrials.gov does not surface for Beta-Thalassemia 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. Beta-Thalassemia is recruiting above its size-band peers.

    8 of 15 indexed trials (53.3%) 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 Beta-Thalassemia research.

    Celgene accounts for 3 of 15 trials (20%). 11 distinct sponsors appear on at least one study for this condition label.

  3. Most Beta-Thalassemia trials plan to enrol fewer than 100 people.

    Median target enrolment is 40 among the 15 trials that report a genuine target (sentinel values excluded). 11 of those (73.3%) plan for fewer than 100 participants.

  4. Beta-Thalassemia research is mostly interventional.

    13 interventional and 2 observational studies make up this index (86.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
