Key findings

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

    15 of 40 indexed trials (37.5%) 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. Sponsorship of Preterm Birth trials is spread across many organizations.

    Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) accounts for 3 of 40 trials (7.5%). 35 distinct sponsors appear on at least one study for this condition label.

  3. Typical Preterm Birth enrolment sits around 221 participants.

    Median target enrolment is 221 among the 40 trials that report a genuine target (sentinel values excluded). 14 of those (35%) plan for fewer than 100 participants.

  4. Preterm Birth research is mostly interventional.

    28 interventional and 12 observational studies make up this index (70% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
