Clinical Research Trials

Key Trial Criteria

• Key Inclusion Criteria

  For a patient to be eligible for participation in this study, all of the following criteria must apply.

  Prior to Step 1 Registration Inclusion Criteria

  • Patients must have pathologically confirmed, previously untreated, unresected squamous cell carcinoma of the larynx, hypopharynx, oropharynx, oral cavity, or carcinoma of unknown head/neck primary within 60 days prior to step 1 registration; submission of hematoxylin and eosin (H&E) stained slides and formalin-fixed and paraffin-embedded (FFPE) tissue block (or punch biopsy of FFPE block) to the biospecimen bank at University of California, San Francisco (UCSF) for central review for oropharyngeal and unknown primaries and for p16 analysis for all other non-oropharyngeal primaries is mandatory for all patients; investigators should check with their pathology department regarding release of biospecimens before approaching patients about participation in the trial; for oropharyngeal and unknown primaries, submission of H&E and p16 stained slides to the biospecimen bank at UCSF for central review is also required prior to step 2 registration
  • Note: fine needle aspirates (FNA) samples are not acceptable since they do not provide enough material for PD-L1 and p16 testing
  • Patients must have locoregionally advanced head and neck squamous cell carcinoma (HNSCC)
    • For p16-positive oropharyngeal/unknown primaries, American Joint Committee on Cancer [AJCC] 8th edition stage III and selected stage I-II based on smoking status in pack-years
