2.Female patients
3.Age >18 years.
4.Pathologically confirmed and documented metastatic breast cancer.
5.Documented HER2-overexpression of the primary or metastatic tumor tissue detected by immunohistochemistry (IHC 3+) and/or genamplification detected by FISH.
6.Disease progression during or after a previous 1st-line chemotherapy* plus trastuzumab treatment as follows:
•Either of taxanes (docetaxel or paclitaxel) + trastuzumab given as 1st-line therapy for palliation

7.Patients are scheduled to receive an effective 2nd-line chemotherapy as per standard medication care. Schedule and dose as investigators’ opinion in the best interest of the patients.
8.Treatment free interval of trastuzumab between 1st-line and 2nd-line administration is a maximum of 6 weeks.
9.At least 4 weeks since major surgery with full recovery.
10.At least 4 weeks since radiotherapy with full recovery.
11.Complete radiology and tumor measurement work up within 5 weeks prior to randomization.
