Key findings

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

    10 of 17 indexed trials (58.8%) 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 HPV Positive Oropharyngeal Squamous Cell Carcinoma trials is spread across many organizations.

    PDS Biotechnology accounts for 2 of 17 trials (11.8%). 15 distinct sponsors appear on at least one study for this condition label.

  3. Most HPV Positive Oropharyngeal Squamous Cell Carcinoma trials plan to enrol fewer than 100 people.

    Median target enrolment is 83 among the 17 trials that report a genuine target (sentinel values excluded). 12 of those (70.6%) plan for fewer than 100 participants.

  4. HPV Positive Oropharyngeal Squamous Cell Carcinoma research is mostly interventional.

    14 interventional and 3 observational studies make up this index (82.4% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
