Key findings

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

    24 of 45 indexed trials (53.3%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. One sponsor concentrates Gastroparesis research.

    Indiana University accounts for 7 of 45 trials (15.6%). 30 distinct sponsors appear on at least one study for this condition label.

  3. Typical Gastroparesis enrolment sits around 65 participants.

    Median target enrolment is 65 among the 45 trials that report a genuine target (sentinel values excluded). 26 of those (57.8%) plan for fewer than 100 participants.

  4. Gastroparesis splits between interventional and observational designs.

    29 interventional and 16 observational studies make up this index (64.4% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
