Phase II Trial Evaluating Axitinib In Patients With Unresectable, Recurrent Or Metastatic Head And Neck Cancer

The subjects will be started on treatment with 5 mg of Axitinib twice a day continuously, with subsequent dose escalation to 7 mg and then 10 mg twice a day in the absence of grade 2 or worse toxicities. This will be followed by clinical and/or radiologic response assessment after 8 weeks and subsequently every 2 months until disease progression (defined per RECIST \[Response Evaluation Criteria In Solid Tumors\] criteria, or obvious progression on clinical or laryngoscopic/endoscopic exam) or intolerable toxicity (defined as below). During treatment on this protocol, all patients will be evaluated for safety. Correlative biomarker analysis will also be conducted.
