Pembrolizumab and Cetuximab in Treating Patients with Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma
This phase II trial studies how well pembrolizumab and cetuximab work in treating patients with head and neck squamous cell carcinoma that has come back or spread to other places in the body. Immunotherapy with monoclonal antibodies, such as pembrolizumab and cetuximab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

- Patient has a known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer
- Patient has known active central nervous system (CNS) metastases and/or carcinomatous meningitis * Note: Patients with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment; this exception does not include carcinomatous meningitis which is excluded regardless of clinical stability
- Patient has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs) * Notes: ** Patients with vitiligo, Grave’s disease, or psoriasis not requiring systemic treatment within the past 2 years are not excluded ** Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment

Trial Objectives and Outline
I. To determine the clinical efficacy of pembrolizumab combined with cetuximab for patients with recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC).
I. To determine 12 month progression-free survival probability.
II. To determine overall survival.
III. To determine duration of response.
IV. To assess safety and tolerability of pembrolizumab combined with cetuximab.
V. To evaluate the correlation between molecular markers and disease outcome.
Patients receive cetuximab intravenously (IV) over 60-120 minutes on days 1, 8, and 15 and pembrolizumab IV over 30 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 28 days and then every 3 months thereafter.
