Key findings

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

    19 of 69 indexed trials (27.5%) 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 Nicotine Dependence trials is spread across many organizations.

    Yale University accounts for 9 of 69 trials (13%). 34 distinct sponsors appear on at least one study for this condition label.

  3. Typical Nicotine Dependence enrolment sits around 104 participants.

    Median target enrolment is 104 among the 68 trials that report a genuine target (sentinel values excluded). 33 of those (48.5%) plan for fewer than 100 participants.

  4. Nicotine Dependence research is mostly interventional.

    64 interventional and 5 observational studies make up this index (92.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
