Inclusion Criteria

1. Patient is an adult = 18 years old at the time of informed consent and has signed informed

consent before any trial related activities and according to local guidelines.

2. Patient has adequate tumor tissue for the analysis of PIK3CA mutational status by a

Novartis designated laboratory. One new or recent biopsy(collected at screening if feasible) or archival tumor block or slides(15 slides

minimum from a surgical specimen, 20 slides minimum from a biopsy) must be provided. it is recommended to provide a tumor sample collected after the most recent progression or recurrence.

3. Patient has identified PIK3CA status (mutant or non-mutant; determined by a Novartis

designated laboratory).

4. If female, then the patient is postmenopausal. Postmenopausal status is defined either by:

a. Prior bilateral oophorectomy

b. Age less than or equal to 60

c. Age greater than 60 and amenorrheic for 12 or more months in the absence of chemotherapy,

tamoxifen, toremifene, or ovarian suppression and Follicle-stimulating Hormone

(FSH) and estradiol in the postmenopausal range per local normal range.

5. Patient has radiological or objective evidence of recurrence or progression.

6. Patient has a histologically and/or cytologically confirmed diagnosis of ER positive and/or PgR positive breast cancer by local laboratory.

7. Patient has HER2-negative breast cancer defined as a negative in situ hybridization test or

an IHC status of 0, 1 positive or 2 positive.If IHC is 2 positive,a negative in situ hybridization (FISH, CISH, or

SISH) test is required by local laboratory testing.

8. Patient has either:

a. Measurable disease, i.e., at least one measurable lesion as per RECIST 1.1 criteria (a

lesion at a previously irradiated site may only be counted as a target lesion if there is

clear sign of progression since the irradiation ) OR

b. If no measurable disease is present, then at last one predominantly lytic bone lesion

must be present (patients with no measurable disease and only one predominantly

lytic bone lesion that has been previously irradiated are eligible if there is documented

evidence of disease progression of the bone lesion after irradiation).

9. Patient has advanced (loco regionally recurrent not amenable to curative therapy or

metastatic) breast cancer.

Patients may be:

a.relapsed with documented evidence of progression while on or after

completion of (neo)adjuvant endocrine therapy with no treatment for metastatic

disease

b.relapsed with documented evidence of progression more than 12 months from

completion of adjuvant endocrine therapy and then subsequently progressed with

documented evidence of progression after one line of endocrine therapy for metastatic

disease

c.newly diagnosed advanced breast cancer, then relapsed with documented evidence of

progression while on or after one line of endocrine therapy.

10. Patient has recurrence or progression of disease during or after AI therapy (i.e. letrozole,

anastrozole, exemestane). AI therapy does not need to be the latest treatment regimen.

11. Patient has an Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.

12. Patient has adequate bone marrow and organ function as defined by the following <br/

Exclusion Criteria

1. Patient with symptomatic visceral disease or any disease burden that makes the patientineligible for endocrine therapy per the investigator’s best judgment.

2. Patient has received prior treatment with chemotherapy (except for neoadjuvant/ adjuvant

chemotherapy), fulvestrant, any PI3K, mTOR or AKT inhibitor

3. Patient has a known hypersensitivity to alpelisib or fulvestrant, or to any of the excipients

of alpelisib or fulvestrant.

4. Patient with inflammatory breast cancer at screening.

5. Patient is concurrently using other anti-cancer therapy.

6. Patient has had surgery within 14 days prior to starting study drug or has not recovered

from major side effects.

7. Patient has not recovered from all toxicities related to prior anticancer therapies to NCI

CTCAE version 4.03 Grade less than or equal to 1. Exception to this criterion: patients with any grade of

alopecia are allowed to enter the study.

8. Patients with Child pugh score B or C.

9. Patient has received radiotherapy less than or equal to 4 weeks or limited field radiation for palliation less than or equal to 2

weeks prior to randomization, and who has not recovered to grade 1 or better from related

side effects of such therapy (with the exception of alopecia) and/or from whom greater than or equal to 25percentage of

the bone marrow was irradiated.

10. Patient has a concurrent malignancy or malignancy within 3 years of randomization, with

the exception of adequately treated, basal or squamous cell carcinoma, non-melanomatous skin cancer or curatively resected cervical cancer.

11. Patients with an established diagnosis of diabetes mellitus type I or not controlled type II

(based on FPG and HbA1c, see inclusion criterion 12)

12. Patient has impairment of gastrointestinal (GI) function or GI disease that may

significantly alter the absorption of the study drugs (e.g., ulcerative diseases, uncontrolled

nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)

13. Patient has a known history of Human Immunodeficiency Virus (HIV) infection (testing

not mandatory)

14. Patient has any other concurrent severe and/or uncontrolled medical condition that would,

in the investigator’s judgment, contraindicate patient participation in the clinical study (e.g chronic active hepatitis, severe hepatic impairment, etc.)

15. Patient has currently documented pneumonitis (the chest CT scan performed at baseline

for the purpose of tumor assessment should be reviewed to confirm that there are no

relevant pulmonary complications present).

16. Patient has clinically significant, uncontrolled heart disease and/or recent cardiac events

including any of the following:

a.History of angina pectoris, coronary artery bypass graft (CABG) symptomatic pericarditis, or myocardial infarction within

12 months prior to study entry

b. History of documented congestive heart failure (New York Heart Association

functional classification III-IV)

c. Documented cardiomyopathy

d.Patient has a Left Ventricular Ejection Fraction (LVEF) less than 50percentage as determined by Multiple Gated acquisition (MUGA) scan or echocardiogram (ECHO)

d.History of any cardiac arrhythmias, (e.g., ventricular tachycardia),complete left bundle block, high
