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

This phase II trial is studying the how well saracatinib works in treating patients with metastatic or recurrent head and neck cancer. Saracatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth

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.

Eligibility Criteria:
Inclusion Criteria:

* Pulmonary fibrosis ≥ grade 2, pleural effusion (non-malignant) ≥ grade 2, or pneumonitis/pulmonary infiltrates ≥ grade 2
* Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study
* Patients who have not recovered from adverse events due to agents administered more than 4 weeks earlier
* Use of specifically prohibited cytochrome P450 3A4 (CYP3A4)-active agents or substances

  * Prohibited drugs should be discontinued 7 days prior to the administration of the first dose of AZD0530 and for 7 days following discontinuation of AZD0530
* Patients receiving any other investigational agents
