Verastem Issues Statement Regarding WCLC Presentations

BOSTON--(BUSINESS WIRE)--Aug. 26, 2015-- Verastem, Inc. (NASDAQ: VSTM), focused on discovering and developing drugs to treat cancer by the targeted killing of cancer stem cells, today issued the following statement in response to inquiries regarding the anticipated oral presentation of VS-6063 (defactinib) data from a Phase 2 study in patients with KRAS mutant non-small cell lung cancer (NSCLC) at the 16thWorld Conference on Lung Cancer (WCLC):

“While updated results from the Phase 2 study of VS-6063 in KRAS mutant non-small cell lung cancer are under embargo until WCLC, Verastem believes the study has met its goals, with encouraging outcomes that the Company plans to explore in future studies. The population explored in this study has refractory, advanced lung cancer, with a median of three prior therapies, and as many as eight prior therapies. The advanced stage of disease led, in some cases, to deaths even in the period between screening and prior to first dose of VS-6063. Two subjects reported as having grade 5 respiratory failure were on multiple concomitant medications and presented with multiple co-morbidities. Both were thoroughly evaluated and reported to the regulatory authorities in 2013 and 2014 when they occurred.

“The totality of safety and efficacy data seen to date with VS-6063 across multiple clinical trials, multiple tumor types and stages of treatment is promising. In addition, in the Company’s registration-directed COMMAND trial in mesothelioma, an independent data safety monitoring board has met and reviewed study data, including adverse events, three times and recommended no changes to study protocol. There have been over 300 patients treated to date with VS-6063, including patients on drug for more than one year. Verastem remains encouraged by the clinical potential of targeting cancer stem cells through FAK inhibition, and is unwavering in its commitment to delivering novel, safe and effective treatments to patients with unmet medical needs.”

About VS-6063

VS-6063 (defactinib) is an orally available compound designed to target cancer stem cells through the potent inhibition of focal adhesion kinase (FAK). Cancer stem cells are an underlying cause of tumor resistance to chemotherapy, recurrence and ultimate disease progression. Research has demonstrated that FAK activity is critical for the growth and survival of cancer stem cells. VS-6063 is currently being studied in the registration-directed COMMAND trial in mesothelioma (, a “Window of Opportunity” study in patients with mesothelioma prior to surgery, a Phase 1/1b study in combination with paclitaxel in patients with ovarian cancer, a trial in patients with KRAS-mutated non-small cell lung cancer and a trial evaluating the combination of VS-6063 and VS-5584 in patients with relapsed mesothelioma. VS-6063 has been granted orphan drug designation for use in mesothelioma in the U.S. and EU.
