Study Summary

The purpose of this study is to evaluate the results of treating patients with HPV-unrelated head and neck squamous cell carcinoma with neoadjuvant single-agent palbociclib, followed by chemoradiation (either cisplatin + IMRT or cetuximab + IMRT depending on patient characteristics), followed by adjuvant single-agent palbociclib.

Primary Outcome

* Tumor response rate is defined as the proportion of subjects who achieve a complete response (CR) or partial response (PR) based on RECIST criteria * CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (\<10 mm short axis). * PR: At least a 30% decrease in the sum of the d
