Key findings

What ClinicalTrials.gov does not surface for Oropharyngeal Squamous Cell Carcinoma 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. Oropharyngeal Squamous Cell Carcinoma is recruiting above its size-band peers.

    11 of 15 indexed trials (73.3%) 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. Sponsorship of Oropharyngeal Squamous Cell Carcinoma trials is spread across many organizations.

    National Cancer Institute (NCI) accounts for 2 of 15 trials (13.3%). 14 distinct sponsors appear on at least one study for this condition label.

  3. Typical Oropharyngeal Squamous Cell Carcinoma enrolment sits around 112 participants.

    Median target enrolment is 112 among the 15 trials that report a genuine target (sentinel values excluded). 7 of those (46.7%) plan for fewer than 100 participants.

  4. Oropharyngeal Squamous Cell Carcinoma splits between interventional and observational designs.

    10 interventional and 5 observational studies make up this index (66.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
