Exclusion Criteria:

  1. Prior therapy with mechanistic target of rapamycin (mTOR), phosphoinositide-3-kinase (PI3K), or dual PI3K-mTOR inhibitors, serine/threonine-specific protein kinase (AKT) inhibitors, or fulvestrant.
  2. Prior treatment with >1 line of chemotherapy for metastatic breast cancer or for locoregional recurrence that was not amenable to resection or radiation therapy with curative intent.
  3. Experienced PD on >2 endocrine therapies for metastatic breast cancer or for locoregional recurrence that was not amenable to resection or radiation therapy with curative intent.
  4. Life-threatening metastatic visceral disease (defined as extensive hepatic involvement or symptomatic pulmonary lymphangitic spread).
