• Patients will eligible if they have tumors that express one of the motesanib-directed tyrosine kinase markers, the target markers:(PDGFR, VEGFR, c-Kit) as determined by study pathologist. Immunohistochemical assays for these markers are provided by grant consortium partner and CLIA-certified diagnostics laboratory MDRG.
• Measurable disease per RECIST (Response Evaluation Criteria in Solid Tumor) guidelines.

• Complete radiology and tumor measurement within 4 weeks (28 days) prior to enrollment.

  • Chest: CT scan with intravenous contrast if the contrast is not medically contraindicated.
  • Abdomen: CT scan with intravenous and oral contrast if the contrast is not medically contraindicated.
  • Pelvis: CT scan with intravenous and oral contrast if the contrast is not medically contraindicated.
  • Brain: CT scan or MRI
  • Bone: Whole body Bone Scintigraphy or PET scan
• Female 18 years of age or older at the time the written informed consent is obtained.
• ECOG Performance Status of 0 or 1.

• Adequate organ and hematological function as evidenced by the following laboratory studies within 2 weeks (14 days) of study enrollment, unless stated otherwise:

  • Cardiac function, as follows:

    • Normal sinus rhythm (no significant ECG changes)

    • Urinary protein quantitative value of ≤ 30 mg/dL in urinalysis or ≤ 1 + on dipstick unless protein is < 500 mg in a 24-hour urine sample.

  • Hepatic function, as follows:

    • Aspartate aminotransferase (AST) ≤ 2.5 x ULN
    • Alanine aminotransferase (ALT) ≤ 2.5 x ULN
    • Total bilirubin ≤ 1 x ULN

• More than 4 weeks since prior therapy for breast cancer
• No other concurrent investigational or commercial agents or therapies for metastatic breast cancer
• No prior capecitabine or fluorouracil for metastatic breast cancer
• More than 4 weeks since prior radiotherapy **Previously irradiated area(s) must not be the only site of disease**

Exclusion Criteria:

Disease Related:

• Current or prior history of central nervous system metastasis.
• Common Terminology Criteria for Adverse Events (CTCAE) v. 3.0 peripheral neuropathy ≥ grade 2 at enrollment.

• Minor surgical procedure, placement of access device, or fine needle aspiration within 7 days of enrollment.
• Known positive test for human immunodeficiency virus (HIV), hepatitis C, or malignancy (other than in situ cervical cancer, or basal cell cancer of the skin), unless treated with curative intent and without evidence of disease for ≥ 3 years before study enrollment.
• Clinically significant cardiac disease within 12 months of study enrollment, including myocardial infarction, unstable angina, grade II or greater peripheral vascular disease, cerebrovascular accident, transient ischemic attack, congestive heart failure, or ongoing arrhythmias requiring medication or pacemaker.
