Brief Summary:
The study is a randomized, double blind, placebo controlled, Phase 3 clinical trial with the primary objective of demonstrating the efficacy of palbociclib in combination with Endocrine therapy over Endocrine therapy alone measured by PEPI and EndoPredict™ EPclin Score in women with operable HR+, HER2 negative breast cancer . The Clinical Response Rate, drop in Ki67 index ≤ 2.7% and Breast conserving rate will be compared between two arms.

Drug: Endocrine therapy
Pre- and peri-menopausal women will be receiving Ovarian Function Suppression (OFS) by either leuprorelin subcutaneous 3.75 mg q28days or goserelin subcuta-neous 3.6 mg q28days plus tamoxifen 20 mg QD in 28-day cycles. Post-menopau-sal women will receive letrozole 2.5 mg QD in 28-day cycles.




Primary Outcome Measures :
  1. Pre-operative Endocrine Prognostic Index (PEPI Score) [ Time Frame: 4 months ]

    The PEPI score is derived from four factors assigned a numerical score following neoadjuvant endocrine therapy, ( including Ki67 expression in the surgical specimen, pathologic tumor size, lymph node status, and estrogen receptor (ER) level).

    The PEPI score is the sum of each component score and shows the risk points for relapse-free survival. PEPI=0 means low risk. PEPI= 1 to 3 means intermediate risk .

    PEPI more than 4 means high risk.


  2. EndoPredict™ EPclin Score [ Time Frame: 4 months ]

    EndoPredict is a multigene test used to predict the risk of distant recurrence of early stage, ER positive ,HER-2 Negative invasive breast cancer. EndoPredict Clinical Score (EP clin ) categorizes patinets into low and high risk groups.Combination of the 12-Gene Molecular Score, tumor stage and lymph node status, generating an EPclin Risk Score.The EPclin Risk Score is calculated, according to the model, as:

    EPclin Risk Score = (0.35 * tumor size) + (0.64 * lymph node status) + (0.28 * 12-Gene Molecular Score) EPclin Risk Scores from 1.0 through 3.3 shows low risk of recurrencein 10 years.EPclin Risk Scores from 3.4 through 6.0 shows high risk of recurrence in 10 years.



Secondary Outcome Measures :
  1. Clinical Response Rate [ Time Frame: 4 months ]
    Observing any reduction in largest tumor diameter on clinical breast examination and ultrasound imaging of breast and axilla after 4 months

  2. Ki67 change [ Time Frame: 4 months ]
    Drop in Ki67 index to less than or equal to 2.7%

  3. pathological response rate [ Time Frame: 4 months ]
    Evaluating the rate of pathological Complete Response based on assessment of surgical specimen

  4. Breast conserving rate [ Time Frame: 4 months ]
    Calculating the rate of breast conserving surgery based on the number of each surgery type

  5. Number of Participants With Abnormal Laboratory Values and/or Adverse Events That Are Related to Treatment as Assessed by CTCAE v4.03 [ Time Frame: 4 months ]
    Type, incidence, severity (as graded by National Cancer Institute - Common Terminology Criteria for Adverse Events [NCI CTCAE] v4.03), seriousness and relationship to study medications of adverse events (AE) and any laboratory abnormalities
