E.4 | Principal exclusion criteria |
1. Extensive visceral disease including bilateral diffuse lymphangitic involvement of the lung with more than 50% lung involvement, evidence of symptomatic central nervous system (CNS) metastases, extensive hepatic involvement defined as involvement of more than one third of the liver confirmed by sonogram and/or CT scan 2. Subjects with bone as the only site of disease. 3. Prior radiation therapy to the site of measurable disease for subjects with a solitary measurable lesion. 4. History of inflammatory breast cancer (IBC). 5. More than 1 regimen of chemotherapy (including antibody and/or cytotoxic therapy) in the metastatic setting. Subjects may have received prior adjuvant or neoadjuvant chemotherapy. 6. Chemotherapy or immunosuppressive agents <=2 weeks prior to day 1 of treatment on study, with the exception of systemic corticosteroids administered for physiologic replacement, or as an antiemetic after discussion with the medical monitor. 7. Hormonal treatment (including aromatase inhibitors) in the metastatic setting with the exception of prior short-term (< 14 days consecutive) use. 8. Adjuvant trastuzumab (Herceptin) or tamoxifen <= 2 weeks prior to day 1 of treatment on study. 9. Aromatase inhibitors as adjuvant therapy <= 12 months prior to day 1 of treatment on study. 10. Disease refractory (i.e., PD within 6 months from initiation of therapy) to previous adjuvant antiestrogen therapy. 11. Major surgery, biological therapy, immunologic therapy or local radiotherapy (subjects must not have had prior cumulative radiotherapy to more than 25% of the marrow) <= 2 weeks prior to day 1 of treatment on study. |

E.5 End points |
E.5.1 | Primary end point(s) |
Overall progression free survival is the primary endpoint of the study, and the clinical activity evaluation will be made using the RECIST guidelines. Non-target lesions, including bone disease, will only be assessed for CR, incomplete response/SD, and PD. |
