Primary Outcome Measures:
  • Progression-free Survival (PFS) [ Time Frame: Baseline until disease progression, assessed throughout entire study duration (up to approximately 27 months) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percent Reduction in Sum of Target Lesion Sizes [ Time Frame: Baseline to Week 16 ] [ Designated as safety issue: No ]
  • Objective response rate (ORR) [ Time Frame: Baseline until participant no longer responds to treatment, assessed throughout entire study duration (up to approximately 27 months) ] [ Designated as safety issue: No ]
  • Overall survival (OS) [ Time Frame: Baseline until death, assessed throughout entire study duration (up to approximately 27 months) ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Females with a histologically confirmed diagnosis of breast cancer that is metastatic or locally advanced (locally advanced tumors must not be amenable to

surgery or radiation therapy with curative intent) with the following pathological characteristics determined locally: estrogen receptor positive and Human Epidermal Growth Factor Receptor 2 (HER-2) negative, and Ki67 (a tumor marker) ≥ 15% determined by the central study laboratory

  • Post-menopausal
  • With advanced breast cancer whose disease was refractory to previous letrozole or anastrozole
  • Has at least one confirmed measurable metastatic lesion
  • Has a performance status ≤ 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale
  • Has a life expectancy of at least 3 months
  • Adequate organ function

Exclusion Criteria:

  • Is receiving any other concurrent systemic tumor therapy, including

hormonal agents and HER-2 inhibitors

  • Previously received rapamycin or rapamycin analogs, including

ridaforolimus, temsirolimus, or everolimus

  • Received prior treatment with Insulin-like Growth Factor 1 Receptor (IGF-1R) inhibitors, Phosphatidylinositol 3-Kinase (PI3K) inhibitors, or

other experimental agents that target PI3K, Protein Kinase B (AKT), or Mammalian Target of Rapamycin (mTOR) pathway

  • Is receiving chronic corticosteroids administered at doses greater than

those used for normal replacement therapy

  • Has active brain metastasis or leptomeningeal carcinomatosis; patients

with adequately treated brain metastases are eligible if they meet certain criteria

  • Known allergy to macrolide antibiotics
  • Has an active infection requiring antibiotics
