“We are encouraged by the initial clinical data presented today by GSK,” said Dr. Joanna Horobin, Verastem Chief Medical Officer. “Merlin loss occurs in approximately 50% of mesothelioma patients and we believe that VS-6063 has potential as a targeted therapy in this disease. We are moving rapidly to initiate a potentially pivotal, double blind controlled study next year.”
FAK is a cytoplasmic tyrosine kinase that mediates signal transduction by integrins and growth factor receptors. FAK has been implicated in different steps of tumor development including tumor initiation, growth, angiogenesis and metastasis. Verastem has pioneered research on FAK as a critical regulator of cancer stem cells using technology developed by cofounder and chair of the Scientific Advisory Board, Robert Weinberg, Ph.D.
The poster presentation by Verastem is titled: “FAK Inhibitor VS-4718 Attenuates Breast Cancer Stem Cell Function and Inhibits Tumor Growth
The poster presentation by GlaxoSmithKline is titled: “Loss of the Tumor Suppressor Merlin as a Potential Predictive Biomarker of Clinical Activity for the Oral, Focal Adhesion Kinase (FAK) Inhibitor GSK2256098 in Pts with Recurrent Mesothelioma.”
VS-6063 is an oral small molecule inhibitor of focal adhesion kinase (FAK). FAK is critical for the survival of cancer stem cells, which are an underlying cause of tumor recurrence and metastasis. VS-6063 was well-tolerated and demonstrated signs of clinical activity in a Phase 1 study in advanced solid tumors. Verastem has demonstrated that loss of the tumor suppressor Merlin confers increased susceptibility to FAK inhibition. Verastem is planning to initiate multiple clinical trials in 2013 with VS-6063, including a potential registration study in mesothelioma, which will evaluate patient response based on Merlin status.

This press release includes forward-looking statements about the Company’s strategy, future plans and prospects, including statements regarding the development of the Company’s compounds, including VS-6063 and VS-4718, and the Company’s FAK and diagnostic programs generally, the timeline for clinical development and regulatory approval of the Company’s compounds and the structure of the Company’s planned clinical trials. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “target,” “potential,” “will,” “would,” “could,” “should,” “continue,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Each forward-looking statement is subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in such statement. Applicable risks and uncertainties include the risks that the preclinical testing of the Company’s compounds may not be predictive of the success of later clinical trials, that the Company will be unable to successfully complete the clinical development of its compounds, including VS-6063 and VS-4718, that the development of the Company’s compounds will take longer or cost more than planned, and that the Company’s compounds will not receive regulatory approval or become commercially successful products. Other risks and uncertainties include those identified under the heading “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 and in any subsequent SEC filings.
