Inclusion Criteria

1.Written informed consent prior to beginning specific protocol procedures, including expected cooperation of the patients for the treatment and follow-up, must be obtained and documented according to the local regulatory requirements.
2.Histologically confirmed invasive adenocarcinoma of the breast.
3.Primary tumour or metastasis negative or positive (= 10% positive stained cells) for oestrogen- and/or progesterone receptor detected by immunohistochemistry.
4.Single or multiple bone metastasis (x-ray, CT or MRI) as only metastatic site.
5.Postmenopausal hormone receptor positive patients should have received an aromatase inhibitor in any given previous breast cancer therapy. Concurrent endocrine treatment for metastatic bone disease is obligatory. Previous treatment with bisphosphonates is allowed.
6.Up to one previous chemotherapy for metastatic disease is allowed
7.Patients must have target lesions according to the WHO criteria.
8.At least 1 target lesion must be completely outside the radiation portal or there must be pathologic proof of progressive disease.
9.At least 2 weeks since major surgery with full recovery.
10.Complete staging within 4 weeks prior to registration.
11.Karnofsky performance status evaluation ? 60%.
12.Age >18 years.
13.Absolute neutrophil count ?1,500 cells/?l, platelet count ?100,000 cells/?l.
14.Bilirubin ?1.5x the upper normal limit for the institution (UNL); elevation of transaminases, alkaline phosphatase <2.5x UNL and serum albumin = 30g/l. Normal renal function (creatinine < or equal 1.5x upper normal limit)
15.If of childbearing potential, negative pregnancy test. In addition the patient has to agree to use an effective method to avoid pregnancy for the duration of the study.

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range

2.Concurrent immunotherapy or hormone replacement therapy and use of hormonal contraceptives.
3.Need for chemotherapy or irradiation of bone metastasis during study treatment.
4.HER2 pos. primary tumour and/ or metastatic lesion.
5.Evidence of metastasis in other organs
6.Uncompensated diabetes mellitus; fasting value of blood sugar of >120 (mg/dl)
7.Corrected (adjusted for serum albumin) serum calcium concentration <8.0 mg/dl (2.00 mmol/l) or ? 12.0 mg/dl (3.00 mmol/l)
8.Abnormal renal function as evidenced by a calculated creatinine clearance < 30 ml/minute.
9.Life expectancy of less than 3 months.
10.Serious intercurrent medical or psychiatric illness that may interfere with the planned treatment (including AIDS and serious active infection).
11.History of other malignancy within the last 5 years which could affect the diagnosis or assessment of metastatic breast cancer.
12.Concurrent treatment with other experimental drugs. Participation in another clinical trial with any investigational not marketed drug within 30 days prior to study entry.
13.Patients being treated with drugs recognized as being strong inhibitors or inducers of theisoenzyme CYP3A (e.g. Rifabutin, Rifampicin, Clarithromycin, Ketoconazole, Itroconazole, Ritinavir, Telithromycin, Erythromycin, Verapamil, Diltazem, see Appendix) within the last 5 days or the expected need for these treatments during study participation.
