Saracatinib in Treating Patients With Recurrent or Metastatic Head and Neck Cancer

PRIMARY OBJECTIVES:

I. To determine the median progression-free survival for patients with advanced or recurrent squamous cell carcinoma of the head and neck (HNSCC) treated with AZD0530 (saracatinib).

SECONDARY OBJEC TIVES:

I. To determine overall survival for patients with advanced or recurrent HNSCC treated with AZD0530.

II. To determine objective response rate for patients with advanced or recurrent HNSCC treated with AZD0530.

III. For patients with accessible tumors, to perform pre and post-treatment biopsies to assess the pharmacodynamic effects of AZD0530 on c-Src and downstream signaling molecules STAT3 and STAT5.

OUTLINE:

Patients receive saracatinib orally (PO) or by percutaneous endoscopic gastrostomy (PEG) tube once daily (QD) on days 1-56. Courses repeat every 8 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 12 weeks and then periodically thereafter.
