Summary:

      A Window of Opportunity Clinical Trial. This study design permits examination of effects of
      an oral agent on cancer patients during the "window" between diagnosis of their cancer and
      their definitive cancer surgery. Similar to a phase 0 study, the trial design permits
      examination of the biologic effects of an agent; in this study pharmacokinetic properties
      will be examined.
