3. Subjects must have recovered from toxicities of prior therapies. (i.e. CTCAE - grade 2).

4. Performance status: ECOG - 1 and life expectancy - 3 months.

5. Organ Function Requirements â?? Subjects must have adequate organ functions as defined

below:

- AST/ALT <= 3X ULN (upper limit of normal)

- AST/ALT ï?£ 5X ULN [with underlying Liver Metastasis]

- Total Bilirubin ï?£ 2.0 X ULN

- Serum Creatinine ï?£ 1.5X ULN

6. Ability to understand and the willingness to sign a written informed consent document

according to institutional guidelines.

7. All positive or negative ER (estrogen receptor), PR (progesterone receptor), HER-2 subjects are eligible for this study.

- Subjects who desire to enroll in this study and for whom anti-HER-2 therapy is not

available or contraindicated, may be eligible to enroll in this trial.

2. Subjects with more than 2 events of disease progression (PD) after the development of

metastatic breast cancer.

3. Subjects who are currently receiving any other concomitant anticancer therapy with the

EXCEPTION of bisphosphonates and hormone therapy.

- During the study period, subjects using hormonal therapy and bisphosphonates should

maintain a constant dose and should not change existing regimen.

- However, if a change in hormonal therapy is indicated, e.g. due to intolerable adverse

4. Subjects with metastasis limited to the bone only and with no history of other visceral or

soft tissue metastases.

5. Subjects with evidence or history of CNS metastases.

10. Subjects with any known uncontrolled inter-current illness including ongoing or active

infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac

arrhythmia, or psychiatric illness/social situations that would limit compliance with study

requirements.

11. Subjects with any of the following MEDICATIONS within 4 weeks prior to randomization:
