Key findings

What ClinicalTrials.gov does not surface for Neonatal Abstinence Syndrome 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. Neonatal Abstinence Syndrome is recruiting below its size-band peers.

    2 of 18 indexed trials (11.1%) 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 Neonatal Abstinence Syndrome research.

    T. John Winhusen, PhD accounts for 3 of 18 trials (16.7%). 15 distinct sponsors appear on at least one study for this condition label.

  3. Most Neonatal Abstinence Syndrome trials plan to enrol fewer than 100 people.

    Median target enrolment is 60 among the 18 trials that report a genuine target (sentinel values excluded). 16 of those (88.9%) plan for fewer than 100 participants.

  4. Neonatal Abstinence Syndrome research is mostly interventional.
