  • Recovered from any previous therapy related toxicity to <= Grade 1 at study entry (except for stable sensory neuropathy <=Grade 2 and alopecia)
  • Written informed consent that is consistent with ICH-GCP guidelines and local regulations

Inclusion criteria for the biopsy substudy are identical to the main study of the phase II part except for the following two inclusion criteria:

  • Fresh tumor biopsy should be taken when deemed safe and feasible by the investigator and upon informed consent by the patient. Bone lesion is not recommended for biopsy
  • Patients eligible to undergo tumor biopsy should have normal coagulation parameters (INR and PTT within normal range)

Exclusion criteria:

  • Previous treatment with agents targeting on IGF pathway, phosphoinositide 3-kinase (PI3K) signaling pathway, protein kinase B (AKT), or mammalian target of rapamycin (mTOR) pathways
  • Prior treatment with exemestane
  • Known hypersensitivity to monoclonal antibody, mTOR inhibitors (e.g. sirolimus), or to the excipients of any study drugs
  • Ovarian suppression by ovarian radiation or treatment with a luteinizing hormone-releasing hormone (LH-RH) agonist
  • Less than one week after receiving immunization with attenuated live vaccines prior to study treatment
  • Radiotherapy within 4 weeks prior to run-in treatment, except in case of localized radiotherapy for analgesic purpose or for lytic lesions at risk of fracture which can then be completed within two weeks prior to study treatment
  • Chemotherapy, biological therapy (other than bevacizumab), immunotherapy or investigational agents within 5 half-life of the drug or within two weeks prior to the start of study treatment, whichever is longer; bevacizumab treatment within 4 weeks prior to start of study treatment
  • Hormonal treatment for breast cancer within 2 weeks prior to start of study treatment
  • Major surgery in the judgement of the investigator within 4 weeks before starting study treatment or scheduled for surgery during the projected course of the study
