Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Neoplasms, Oral Mouth Neoplasms Drug: GSK1120212 Phase 2

Detailed Description:
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.

GSK1120212 2 mg PO daily for a total of 14 days with the intent of the last pill being the day before surgery.
Drug: GSK1120212
Trametinib (GSK1120212) is a selective MEK1 and MEK2 inhibitor with selective activity towards BRAF and RAS mutant cancer cell lines and hematopoietic cancer cells from AML and CML origins.
Other Names:
  • Trametinib
  • Mekinist

Primary Outcome Measures :
  1. Number of Participants With Changes in Putative Tumor Initiating Cell Populations as Defined by Cell Surface CD44 and Intracellular Phospho-ERK1/2 Staining After Treatment With GSK1120212. [ Time Frame: Baseline and Day 15 ]
    Pre-post measure of p-EKP expression was measured by change in staining intensity and quartile distribution.

  2. Number of Participants With Changes in TumorCell Surface CD44 Expression After Treatment With GSK1120212. [ Time Frame: Baseline and Day 15 ]
    Pre-post measure of CD44 expression using IHC.

Secondary Outcome Measures :
  1. Tumor Specific Findings for Pathologic Changes Including Proliferation (Ki-67 Staining), Tumor Vasculature Staining (Microvessel Density), ERK1/2 Mediated Changes in p27 (Kip1) & Flow Cytometric Analysis of the Peripheral Blood & Tumor. [ Time Frame: Baseline and Day 15 ]
  2. Percentage of Participants With Clinical Response Induced by GSK1120212, as Determined by Change in Tumor Size. [ Time Frame: Baseline and Day 15 ]
    Clinical Response was evaluted by quantitative changes in tumor size based on clinical examination of area of tumor at baseline and after GSK1120212 based on two dimensional measurements.

  3. Flow Cytometric Analysis of the Peripheral Blood and Tumor. [ Time Frame: Baseline, Day 14, and Day 15 ]

    Peripheral blood - baseline and Day 14

    Tumor - baseline and Day 15

  4. Percent Change in Maximum Standard Uptake Value in Oral Cavity Saqumous Cell Carcinoma (OCSCC) Using F18-Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography (FDG-PET/CT). [ Time Frame: Baseline and Day 14 ]
  5. Safety of GSK1120212 [ Time Frame: 1st 4-6 week follow-up visit ]
    Number of adverse events were monitored for 30 day following last dose of GSK1120212

  6. Percent Change in Tumor Size Area [ Time Frame: Baseline and Day 15 ]
  7. Percent of Participants With Metabolic Changes in OCSCC Using FDG-PET/CT Imaging. [ Time Frame: Baseline and Day 14 ]
    Intratumarol metabolic changes were evaluated by changes in in SUVmax in the primary tumor; quantitative analysis SUVmax with the primary tumor site was determined within a volume of interest around the tumor using a Siemens eSoft workstation.
