Brief Summary:
Everolimus will be given to patients with metastatic breast cancer who already has a progress taking Everolimus but with a change in the endocrine treatment.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Drug: Everolimus Drug: Everolimus-placebo Phase 3

Detailed Description:
With continuation of endocrine treatment of breast cancer an adaptive upregulation of different signaling cascades including the PI3K/akt/mTOR pathway results in cell growth stimulation and results in resistance to endocrine therapies. One way to restore endocrine sensitivity is the inhibition of the mTOR pathway in combination with endocrine therapy leading to an increase in PFS compared with endocrine therapy alone. Guidelines recommend the sequential treatment with different endocrine therapies. It therefore appears reasonable to explore if sensitivity can be restored by changing the subsequent endocrine combination partner of Everolimus in case of failure of a combined endocrine-everolimus therapy.

Primary Outcome Measures :
  1. progression free survival [ Time Frame: 3 years ]
    comparison of progression free survival between the two arms: with Everolimus or with Everolimus-placebo

Secondary Outcome Measures :
  1. overall survival [ Time Frame: 3 years ]
    comparison of the overall survival between the 2 arms

  2. clinical benefit Rate(CBR) [ Time Frame: 3 years ]
    Clinical Benefit Rate (CBR) is defined as all patients with a complete, partial response and stable disease for at least 24 weeks

  3. chemo-free interval [ Time Frame: 3 years ]
    chemo-free interval is defined as time from last day of chemotherapy in the metastatic setting until first day of next chemotherapy or in patients who have not received chemotherapy in the metastatic setting: the first diagnosis of metastases until start of 1st-line chemotherapy in the metastatic setting.

  4. safety by toxicity [ Time Frame: 3 years ]
    Safety by toxicity grades is defined by the NCI-CTCAE version 4.03

  5. compliance [ Time Frame: 3 years ]
    Compliance will be assessed by the number and reasons of patients whose treatment had to be reduced, delayed or permanently stopped

  6. biological marker [ Time Frame: starting in 3 years, biomaterial will be stored, later research possible ]
    Bone marker estimation in blood and/or urine

Other Outcome Measures:
  1. translational research: search for markers for prediction [ Time Frame: starting in 3 years, biomaterial will be stored, later research possible ]
    PI3K/mTor and other related markers in tissue collected directly before study entry

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

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. Complete baseline documentation must be submitted via the web-based data collection system MedCODES® to the GBG Forschungs GmbH.

    3. Histological confirmed hormone receptor positive (HR+); HER2-negative carcinoma of the breast. Every effort should be made to make paraffin embedded tissue or slides from the original tumor and/or from metastatic tissue available for confirmation of diagnosis and additional translational research.

    4. Postmenopausal women 5. HER2-negative, hormone-receptor-positive, locally advanced or metastatic stage of disease not amenable to curative treatment by surgery or radiotherapy alone.

    6. No indication for chemotherapy 7. Patients must have either measurable or non-measurable target lesions according to RECIST criteria. Complete staging work-up within 4 weeks prior to registration including chest and abdominal CT scan or MRI (exceptionally chest X-ray and abdominal ultrasound), and bone scan. Further tests have to be performed according to RECIST or as clinically indicated.

    8. Disease progression during or after previous exemestane and everolimus treatment as follows (everolimus has to be given previously for at least 12 weeks, treatment-free interval of everolimus for a maximum of 6 weeks until randomization) 9. The following previous systemic treatments are eligible:

  • Previous participation in other everolimus-containing trials, e.g. the GeparQuinto, BOLERO, 4EVER study is allowed.
  • (Neo)Adjuvant and up to 1 chemotherapy regimen for metastatic breast cancer
  • Maximum of two lines as palliative endocrine monotherapy
  • Treatment with bisphosphonates and/or denosumab (adjuvant and/or palliative) 10. At least 4 weeks since radiotherapy, with full recovery. The measurable disease must be completely outside the radiation field or there must be pathologic proof of newly progressive disease.
