GSK1120212 in Surgically Resectable Oral Cavity Squamous Cell Cancer

This phase II trial studies how trametinib effects tumor cells in patients with oral cavity squamous cell carcinoma that can be removed by surgery. Trametinib may shrink the tumor by blocking an enzyme pathway needed for cell growth.

The rationale for this study in oral cavity squamous cell carcinomas rests on pre-clinical findings demonstrating that (a) activation of the ERK1/2 kinases is associated with aggressive features, (b) this aggressive phenotype is directly linked to expression of CD44, a cell surface hyaluronan receptor and (c) this association between activated ERK1/2 and CD44 is also identified in human cell lines and primary tumors. These data suggest that ERK1/2 is targetable biochemical pathway in CD44 expressing cells. These cells represent putative cancer stem cells or tumor initiating cells that have been associated with worse patient outcomes. Thus, the application of GSK1120212 to target OCSCC is a specific translational application of our laboratory findings.

* Patient must not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to GSK1120212 or other agents used in the study.
* Patient must not have any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels.
* Patient must not have an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
