Pharmacodynamic Effects of Ribavirin in Patients With Tonsil and/or Base of Tongue Squamous Cell Carcinoma
Human papillomavirus (HPV-16) is an important factor in the development of many tonsil and/or base of tongue squamous cell cancers. Although HPV-16 is not thought to cause cancer by itself, it appears to contribute to the development of tonsil and/or base of tongue cancer in many patients. It is likely that treatment for many patients with tonsil and/or base of tongue cancer could be improved if effective therapy to control HPV-16 is developed. The investigators in this study want to learn if ribavirin shows evidence of activity against HPV-16.
Ribavirin is a pill therapy that is approved by the Food and Drug Administration (FDA) as part of the standard treatment for Hepatitis C. Laboratory experiments suggest that ribavirin might also be useful in the treatment of head and neck cancers. However, ribavirin has not yet been tested against head and neck cancer in patients. The purpose of this study is to find out the effects of ribavirin on tonsil and base tongue squamous cell cancer in patients.
The main purpose of this study is to see if ribavirin changes the expression of certain proteins related to HPV infection in the tumor. The study will also find out if ribavirin changes how the tumor appears in a PET/CT scan (positron emission tomography/computed tomography scan).

|Official Title:||A Pilot Study to Assess the Pharmacodynamic Effects of Ribavirin in Patients With Tonsil and/or Base of Tongue Squamous Cell Carcinoma|
- To explore if ribavirin therapy for 2 weeks decreases tumor expression [ Time Frame: 2 weeks ]of phosphorylated eIF4E among patients with tonsillar squamous cell carcinoma.
- to explore the pharmacodynamic effects of ribavirin [ Time Frame: pre-treatment and post treatment ]on molecules that may be regulated directly or indirectly by eIF4E (eg, p16, p21, EGFR, p53).). Immunohistochemistry will be performed on Pathology samples (e.g. diagnostic biopsy), as well as on the post-treatment surgical pathology samples (e.g. definitive surgery),to describe the effects of ribavirin treatment on the expression of phosphorylated eIF4E.
- To explore if ribavirin reduces the expression of HPV-16 oncoproteins E6 and E7 [ Time Frame: In pre- and post-treatment tumor samples ]Pathology samples (e.g. diagnostic biopsy), as well as on the post-treatment surgical pathology samples (e.g. definitive surgery)

This will be a single institution non-randomized study for patients with tonsil and/or base of tongue squamous cell cancer. This is a pilot study to obtain pharmacodynamic data regarding the effects of ribavirin on tonsil squamous cell cancer.
The clinical intervention in this study is ribavirin therapy for approximately 14 days. Ribavirin 800 mg/day is administered in divided doses, 400 mg PO qAM and 400 mg PO qPM.
