Molecular Effects of Short-Term Celecoxib Treatment on Head and Neck Squamous Cell Carcinoma

The selective cyclo-oxygenase 2 (COX-2) inhibitor, celecoxib (Celebrex, Pfizer Inc.), is
being investigated as an anticancer agent in chemoprevention and adjuvant therapeutic
regimens in many organ systems including the head and neck, lung, colon, breast and bladder.
The mechanisms of action are not fully defined and, to date, there are no data regarding the
shortterm molecular effects of celecoxib treatment in human tumor tissues. These data are
important for understanding the targets and effects of COX-2 inhibitors in cancer.

Specifically, this pilot study seeks to evaluate the feasibility of determining whether
celecoxib treatment inhibits COX-2 expression, alters the intratumor eicosanoid profile,
and/or suppresses markers of proliferation and growth in human tumor tissues. In addition,
this trial aims to evaluate the feasibility of reliably measuring the effects of celecoxib
treatment on biomarkers of angiogenesis, prostaglandin metabolism and select growth factors.
The study is titled: "Molecular effects of short-term celecoxib treatment on head and neck
squamous carcinoma." In this study, 10 patients identified in the Head and Neck Surgical
Oncology clinic at MSKCC with untreated squamous cell carcinoma of the oral cavity or
oropharynx will be recruited to participate. Participation will not change the standard of
cancer care that the patients receive. At the initial office evaluation the tumor will be
biopsied. Blood and urine will also be collected. Patients will then take oral celecoxib
(400 mg) twice daily starting exactly 5 days prior to staging examination under anesthesia
or definitive resection and including the morning of surgery. The tumor will then be
re-biopsied at the time of staging examination under anesthesia or surgical resection. Blood
and urine will similarly be re-collected at that time.

Inclusion Criteria:

- Untreated squamous cell carcinoma of the oral cavity or oropharynx.

- Older than 18 years of age.

- Understand and sign informed consent.

Exclusion Criteria:

- Any prior treatment of the index cancer (chemotherapy, immunotherapy, hormonal
therapy or radiation therapy) or similar treatment of an unrelated malignancy within
6 weeks of enrollment into this study.

- Breast-feeding, pregnancy or of childbearing potential (including at least two years
post menopause) and unable to confirm adequate contraception (abstinence, IUD, birth
control pills, or spermicidal gel with diaphragm or condom) since last menses.

- History of esophageal, gastric or duodenal ulceration within 6 weeks of enrollment.

- History of acute or chronic renal disorder (blood creatinine level > 1.5 mg/dL).

- History of acute or chronic hepatic disorder or a significant bleeding disorder.

- History of chronic inflammatory disease (e.g. ulcerative colitis, Crohn's
disease,rheumatoid arthritis or pancreatitis).

- History of myocardial infarction, angina, or coronary artery disease within the past
6 months, or active cardiac disease.

- The subject is of New York Heart Association (NYHA) Class 3 or 4 cardiac status.

- Corticosteroid use within 6 weeks of enrollment, excluding topical nasal sprays.

- NSAID (including celecoxib) or aspirin (> 81 mg/day) use within 1 week of enrollment.

- History of hypersensitivity to COX-2 inhibitors, NSAIDs, salicylates, or

- Currently taking fluconazole or lithium.

- Investigational medication use within 6 weeks of enrollment or is scheduled to
receive an investigational drug during the course of the study.

- Principal Investigator deems subject to be at high risk for non-compliance.
