•The patient has confirmed HR+, HER2-negative (HER2-), early stage resected invasive breast cancer without evidence of distant metastases.
•The patient must have undergone definitive surgical treatment of the primary breast tumor(s).
•The patient must have tumor tissue from breast (preferred) or lymph node for exploratory biomarker analysis available prior to randomization.
•The patient must have high risk of disease recurrence based on nodal status, tumor size, or grade regardless of Ki67 status (Cohort 1), or eligible exclusively based on a Ki67 status (Cohort 2)
•The patient must be randomized within 16 months from the time of definitive breast cancer surgery
•If the patient is currently receiving or initiating standard adjuvant endocrine therapy at time of study entry, she/he may receive up to 12 weeks endocrine therapy until randomization following his/her last non-endocrine therapy (surgery, chemotherapy, or radiation), whichever is last.
•Women of reproductive potential must have a negative blood pregnancy test and agree to use highly effective contraceptive methods

Exclusion Criteria

•The patient has metastatic disease (including contralateral axillary
lymph nodes) or lymph node-negative breast cancer. Patients with
inflammatory breast cancer are excluded.
•Patients with a history of previous breast cancer are excluded, with the
exception of ipsilateral DCIS treated by locoregional therapy alone =5
years ago. Patients with a history of contralateral DCIS treated by local
regional therapy at any time may be eligible. Patients with a history of
any other cancer (except non-melanoma skin cancer or carcinoma in situ
of the cervix), unless in complete remission with no therapy for a
minimum of 5 years from the date of randomization are excluded.
•Females who are pregnant or lactating
•The patient has previously received treatment with any CDK4 and CDK6
inhibitor.

therapy (for example, birth control pills or hormone replacement
therapy).
