This phase I trial studies the side effects and best dose of palbociclib, when given together with avelumab and cetuximab, in treating patients with head and neck squamous cell cancer that has come back or spread to other parts of the body. Immunotherapy with monoclonal antibodies, such as avelumab 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. Palbociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving avelumab, palbociclib, and cetuximab may work better in treating patients with recurrent or metastatic head and neck squamous cell cancer.

PRIMARY OBJECTIVES:
I. Identify the maximum tolerated dose (MTD) or recommended phase II dose (RP2D) for the combination of palbociclib, avelumab, and cetuximab.
SECONDARY OBJECTIVES:
I. Response rate by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
II. Overall survival.
III. Progression-free survival.
IV. Safety and toxicity profile.
V. Duration of response.
OUTLINE: This is a dose-escalation study of palbociclib.
Patients receive avelumab intravenously (IV) over 1 hour on days 1 and 15, palbociclib orally (PO) once daily (QD) on days 1-21, and cetuximab IV on days 1, 8, 15, and 22. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 and 90 days, and then for 6 months.
