             Patients may be:

               -  newly diagnosed advanced/metastatic breast cancer, treatment naïve

               -  relapsed with documented evidence of relapse more than 12 months from completion
                  of (neo)adjuvant endocrine therapy with no treatment for advanced/metastatic
                  disease

               -  relapsed with documented evidence of relapse on or within 12 months from
                  completion of (neo)adjuvant endocrine therapy with no treatment for
                  advanced/metastatic disease

               -  relapsed with documented evidence of relapse 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 (with either an
                  antiestrogen or an aromatase inhibitor) for advanced/metastatic disease

               -  newly diagnosed advanced/metastatic breast cancer at diagnosis that progressed
                  with documented evidence of progression after one line of endocrine therapy (with
                  either an antiestrogen or an aromatase inhibitor)

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

          6. Patient has adequate bone marrow and organ function

        Exclusion Criteria:

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

          2. Patient has received prior treatment with chemotherapy (except for neoadjuvant/
             adjuvant chemotherapy), fulvestrant or any CDK4/6 inhibitor.

          3. Patient with inflammatory breast cancer at screening .

          4. Patient with CNS involvement unless they are at least 4 weeks from prior therapy
             completion to starting the study treatment and have stable CNS tumor at the time of
             screening and not receiving steroids and/or enzyme inducing anti-epileptic medications
             for brain metastases

          5. Clinically significant, uncontrolled heart disease and/or cardiac repolarization
             abnormality

          6. Patient is currently receiving any of the following substances and cannot be
             discontinued 7 days prior to start the treatment:

               -  Known strong inducers or inhibitors of CYP3A4/5,

               -  That have a known risk to prolong the QT interval or induce Torsades de Pointes.

               -  Those have a narrow therapeutic window and are predominantly metabolized through
                  CYP3A4/5.

               -  Herbal preparations/medications, dietary supplements.

Measure:Progression Free Survival (PFS)
Time Frame:Up to approximately 26 months

Time Frame:Up to approximately 26 months
Safety Issue:
Description:Safety will be determined by type, frequency and severity of adverse events per CTCAE version 4.03 and type, frequency and severity of laboratory toxicities per CTCAE version 4.03.
Measure:Time to definitive 10% deterioration in the global health status/quality of life (QOL) scale score of the EORTC QLQ-C30
Time Frame:Up to approximately 26 months
Safety Issue:
Description:The time to definitive 10% deterioration is defined as the time from the date of randomization to the date of event, which is defined as at least 10% relative to baseline worsening of the corresponding scale score (without further improvement above the threshold) or death due to any cause.
Measure:Change from baseline in the global health status/QoL scale score of the EORTC QLQ-C30
Time Frame:Up to approximately 26 months
Safety Issue:
Description:Change from baseline in the domain scores, health states, overall health status, and index values at the time of each assessment will be summarized.
Measure:Clinical benefit ratio (CBR)
Time Frame:Up to approximately 26 months
Safety Issue:
Description:Clinical benefit rate (CBR), defined as the proportion of patients with a best overall response of complete response (CR) or partial response (PR) or stable disease (SD) lasting 24 weeks or longer as defined in RECIST 1.1
Measure:Time to response (TTR)
Time Frame:Up to approximately 26 months
Safety Issue:
Description:Time from randomization to the first documented and confirmed response (complete response or partial response) as defined by RECIST 1.1
Measure:Duration of response (DOR)
Time Frame:Up to approximately 26 months
Safety Issue:
Description:Time from the first documented response (CR or PR) to the first documented progression or death due to underlying cancer as defined in RECIST 1.1
