Key findings

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

    0 of 15 indexed trials (0%) 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 Pertussis research.

    Sanofi Pasteur, a Sanofi Company accounts for 6 of 15 trials (40%). 5 distinct sponsors appear on at least one study for this condition label.

  3. Typical Pertussis enrolment sits around 647 participants.

    Median target enrolment is 647 among the 15 trials that report a genuine target (sentinel values excluded). 3 of those (20%) plan for fewer than 100 participants.

  4. Pertussis 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.
