Who can take part

You may be able to join if

  • Participants with histologically or cytologically-confirmed recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) that is considered incurable by local therapies. The eligible primary tumor locations are oropharynx, oral cavity, hypopharynx, and larynx.

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • Adequate organ function per protocol-defined criteria.
  • Documentation of results from testing of human papilloma virus (HPV) status for oropharyngeal cancer.
  • Baseline archival tumor specimen available or willing to undergo a prestudy treatment tumor core or excisional biopsy of a tumor lesion not previously irradiated, to obtain the specimen.

You likely can't join if

  • Carcinoma of the nasopharynx, salivary gland, unknown primary origin, or nonsquamous histologies as primary tumors.
  • Disease progression within 6 months of completion of curatively intended systemic treatment for locoregionally advanced Head and Neck Squamous Cell Carcinoma (HNSCC)
  • Use of protocol-defined prior/concomitant therapy.
