             accepted). Ascites, pleural effusion, and bone metastases are not considered
             measurable but are considered evaluable (non-measurable). Minimum indicator lesion
             size for measurable disease: ≥10 mm measured by spiral computed tomography (CT) or ≥20

                  30 to 50 mL/min) at baseline, a dose reduction to (-1) of the capecitabine
                  starting dose is required.

                  < 10 x ULN in the case of bone disease).

               -  International normalization ratio (INR) < 1.6.

          -  Must have ≤ 1 prior regimen of endocrine therapy for metastatic breast cancer. This
             would include patients who have a recurrence while on adjuvant hormone therapy OR have

             therapy for metastatic breast cancer OR treatment naïve patients who present with
             metastatic breast cancer.

          -  Radiotherapy ≤ 2 weeks prior to registration, except if to a non-target lesion only or
             single-dose radiation for palliation. NOTE: Prior radiation to a target lesion(s) is
             permitted only if there has been clear progression of the lesion since radiation was
             completed.

          -  Life expectancy <3 months.

          -  Serious, uncontrolled, concurrent infection(s).
