Inclution Criteria
Patients must meet the following criteria for study entry:
Disease-Specific Inclusion Criteria
• Women with histologically or cytologically confirmed invasive, ER+ breast cancer:
metastatic or inoperable (not amenable to resection or other local therapy with
curative intent) locally advanced breast cancer
• Patients for whom endocrine therapy (e.g., fulvestrant) is recommended and
treatment with cytotoxic chemotherapy is not indicated at time of entry into the study,
as per national or local treatment guidelines.
• Radiologic/objective evidence of recurrence or progression to the most recent
systemic therapy for breast cancer
• Radiologic/objective evidence of breast cancer recurrence or progression while on
or within 12 months of the end of adjuvant treatment with an AI, or progression while
on or within 1 month of the end of prior AI treatment for locally advanced or MBC.
The AI (letrozole, anastrozole, or exemestane) does not have to be the most recent
treatment before randomization.
• Measurable disease via RECIST v1.1 or non-measurable, evaluable disease with at
least one evaluable bone lesion via RECIST v1.1. Bone lesions that have been
irradiated are not evaluable.
General Inclusion Criteria
• Able and willing to provide written informed consent and to comply with the study
protocol
• Age ≥ 18 years
• ECOG Performance Status of 0 or 1
• Postmenopausal status defined as one of the following:
Age ≥ 60 years
Age < 60 years and postmenopausal as defined by documented
follicle-stimulating hormone and estradiol in the postmenopausal ranges in
addition to being amenorrheic for 12 months in the absence of chemotherapy,
tamoxifen, toremifene, or ovarian suppression
Prior bilateral oophorectomy (≥ 28 days prior to first fulvestrant treatment on
Cycle 1 Day 1)
• Consent to provide a formalin-fixed paraffin-embedded (FFPE) tissue block
(preferred) or a minimum of 20 (25 preferred) freshly cut unstained tumor slides
from the most recently collected, available tumor tissue for PIK3CA-mutation testing
and for other protocol-mandated exploratory assessments
• A valid cobas PIK3CA mutation result (per central testing) is required for all patients
(e.g., patients with an “invalid” or “failed” PIK3CA mutation result are not permitted
to enroll)
After 120 patients whose breast cancers have a “wild-type” (mutation not
detected result) PIK3CA status have been enrolled, all remaining enrolled
patients must have a breast cancer sample that tests positive for PIK3CA
mutation to be eligible.
• Adequate hematologic and end-organ function, defined by the following laboratory
results obtained within 28 days prior to Cycle 1 Day 1:
ANC ≥ 1500/μL (1.5 × 109
/L)
Platelet count ≥ 100,000/μL (100 × 109
/L)
Hemoglobin ≥ 9.0 g/dL (90 g/L)
Total bilirubin ≤ 1.5 × upper limit of normal (ULN) except in patients with
previously documented Gilbert’s syndrome, in which case total
bilirubin ≤ 3 mg/dL
AST and ALT≤ 1.5 ×ULN, with the following exceptions:
Patients with documented liver metastases: AST and/or ALT ≤ 5.0 ×ULN
Serum creatinine ≤ 1.5 ×ULN or creatinine clearance ≥ 50 mL/min based on
Cockcroft−Gault glomerular filtration rate estimation
• Fasting glucose ≤ 125 mg/dL (6.94 mmol/L)
Exclusion Criteria
Patients who meet any of the following criteria will be excluded from study entry:
Disease-Specific Exclusion Criteria
• HER2-positive disease by local laboratory testing (IHC 3+ staining or in situ
hybridization positive)
• Prior treatment with fulvestrant
• Prior treatment with a PI3K inhibitor, mTOR inhibitor (such as everolimus), or AKT
inhibitor. See Appendix 5 for a comprehensive list of excluded treatments.

stable by the investigator
• Prior treatment with > 1 cytotoxic chemotherapy regimen for MBC
• Symptomatic hypercalcemia requiring continued use of bisphosphonate or
denosumab therapy
Use of bisphosphonate therapy or denosumab for other reasons (e.g., bone
metastasis, osteoporosis, etc.) is allowed
• Concurrent hormone replacement therapy
• Known untreated or active CNS metastases (progressing or requiring
anticonvulsants or corticosteroids for symptomatic control); a computed tomography
(CT) scan or magnetic resonance imaging (MRI) of the brain will be performed at
screening if required by the local health authority
Patients with a history of treated CNS metastases are eligible, provided they
meet all of the following criteria:

CNS-directed therapy and no evidence of interim progression between the
completion of CNS-directed therapy and the screening radiographic study

Minimum of 2 weeks between completion of radiotherapy and
Cycle 1 Day 1 and recovery from significant (Grade ≥ 3) acute toxicity with
no ongoing requirement for ≥ 10 mg of prednisone per day or an equivalent
dose of other corticosteroid
• History of other malignancy within the previous 5 years, except for appropriately
treated carcinoma in situ of the cervix, non-melanoma skin carcinoma,
Stage I uterine cancer, or patients who have undergone potentially curative therapy
with no evidence of disease and are deemed by the treating physician to be at low
risk for recurrence
General Exclusion Criteria
• Type 1 or Type 2 diabetes mellitus requiring anti-hyperglycemic medications
• Clinically significant cardiac or pulmonary dysfunction, including the following:
Current uncontrolled Grade ≥ 2 hypertension or unstable angina
Symptomatic congestive heart failure or serious cardiac arrhythmia requiring
treatment, with the exceptions of atrial fibrillation and paroxysmal
supraventricular tachycardia or a conduction abnormality that has been treated

presence of positive test results for hepatitis B (hepatitis B surface antigen
and/or total hepatitis B core antibody) or HCV antibody. Unless required by
local regulations, patients are not required to have HIV, HBV, or HCV
assessments at screening if these assessments have not been previously
performed.
Patients who test positive for hepatitis B core antibody are eligible only if
test results are also positive for hepatitis B surface antibody and
