- Female patients at least 18 years old with HER-2 negative breast cancer. -Patients must have evidence of HER-2 or EGFR positive circulating tumour cells in a peripheral blood sample taken at screening visit. -Patients must have measurable, metastatic disease and no brain metastasis requiring local therapy. -Other criteria include ECOG score 0 to 2, life expectancy > 12 weeks, baseline organ function at screening visit, -Previous treatment with anthracyclines and/or taxanes in the neo-adjuvant, adjuvant or advanced setting, and at least one line of treatment for metastatic disease.
- Unstable medical conditions, pregnant or lactating women. -Inability to provide informed consent. -Lack of physical integrity of the upper gastrointestinal (GI) tract. -Co-existing malignancy or malignancies within the last 5 years with the exception of basal cell carcinoma or in-situ carcinoma, concurrent anti-cancer therapies (chemo or hormonal therapy) or investigational drugs other than study drug. -Concurrent radiotherapy to the only target lesion or concurrent bisphosphonates if bone metastases are the only target lesions. -Previous treatment with anti HER-2 or anti-EGFR therapies. -Protocol specified treatment regimens that would be inappropriate for the management of the subject.
