Key findings

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

    77 of 194 indexed trials (39.7%) 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 Pregnancy trials is spread across many organizations.

    Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) accounts for 8 of 194 trials (4.1%). 137 distinct sponsors appear on at least one study for this condition label.

  3. Typical Pregnancy enrolment sits around 150 participants.

    Median target enrolment is 150 among the 192 trials that report a genuine target (sentinel values excluded). 72 of those (37.5%) plan for fewer than 100 participants.

  4. Pregnancy splits between interventional and observational designs.

    115 interventional and 79 observational studies make up this index (59.3% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
