Efficacy of SU 011248 in Head And Neck Carcinoma

Study Overview
=================
Brief Summary
-----------------
Preclinical studies as well as phase I and II trials have demonstrated that SU11248 has antitumor activity in renal cell carcinoma, breast cancer, neuroendocrine tumor and GIST. So at the light of these pre-clinical and clinical data, it seems interesting and promising to test SU011248 in these poor prognosis patients.

Detailed Description
-----------------
This is an open-label phase II, multicenter study. Eligible patients will receive SU011248 in monotherapy (37.5 mg given continuously without interruption). Tumor check-up will be performed every 6-8 weeks. Treatment will be continued until disease progression or unacceptable toxicities according to the patient or the investigator (the median for treatment in renal cell study was 8 months). Since, head and neck tumors are easily accessible for iterative biopsy, this study will offer the opportunity to get tumor biopsies before and after SU011248. Our study will allow translational research with biopsies at crucial timing: at baseline before any treatment, , during the treatment with SU011248 (cycle 1, between week 4 and 6), for patients with stable disease or partial response, a new biopsy will be performed at the time of disease progression to try to understand the mechanisms of tumor or resistance.
