Verastem, Inc., (NASDAQ: VSTM) a biopharmaceutical company focused on 
      discovering and developing drugs to treat breast and other cancers by 
      targeting cancer stem cells, today reported financial results for the 
      quarter ended June 30, 2012, and also commented on certain corporate 
      accomplishments and plans.
   
"We made significant advances in our therapeutic programs during the 
      second quarter," said Christoph Westphal, M.D., Ph.D., Chairman, 
      President and Chief Executive Officer of Verastem. "The acquisition of 
      the Phase 2-ready focal adhesion kinase inhibitors from Pfizer 
      accelerates this key cancer stem cell-targeting program by approximately 
      12-18 months, and we are now positioned to initiate a potential 
      registration study in mesothelioma next year."
