Key findings

What ClinicalTrials.gov does not surface for Small-cell Lung Cancer 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. Small-cell Lung Cancer is recruiting above its size-band peers.

    38 of 80 indexed trials (47.5%) 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 Small-cell Lung Cancer trials is spread across many organizations.

    Amgen accounts for 5 of 80 trials (6.3%). 67 distinct sponsors appear on at least one study for this condition label.

  3. Typical Small-cell Lung Cancer enrolment sits around 80 participants.

    Median target enrolment is 80 among the 80 trials that report a genuine target (sentinel values excluded). 42 of those (52.5%) plan for fewer than 100 participants.

  4. Small-cell Lung Cancer research is mostly interventional.

    71 interventional and 9 observational studies make up this index (88.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
