  • Patient has breast cancer that is positive for ER and/or PgR
  • Patient has HER2-negative breast cancer
  • Patient has available archival tumor tissue from the surgical specimen
  • Patient after surgical resection where tumor was removed completely, with the final surgical specimen microscopic margins free from tumor, and belongs to one of the following categories: anatomic stage group II or III
  • If indicated, patient has completed adjuvant and/or neoadjuvant chemotherapy according to the institutional guidelines
  • If indicated, patient has completed adjuvant radiotherapy according to the institutional guidelines
  • Patient has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.

Exclusion Criteria

  • Patient has received any CDK4/6 inhibitor
  • Patient has received prior treatment with tamoxifen, raloxifene or AIs for reduction in risk ("chemoprevention") of breast cancer and/or treatment for osteoporosis within the last 2 years prior to PICF signature
  • Patient has received prior treatment with anthracyclines at cumulative doses of 450 mg/m² or more for doxorubicin, or 900 mg/m² or more for epirubicin. Patient with a known hypersensitivity to any of the excipients of ribociclib and/or ET
  • Patient with distant metastases of breast cancer beyond regional lymph nodes (stage IV according to AJCC 8th edition) and/or evidence of recurrence after curative surgery.
  • Patient is concurrently using other anti-neoplastic therapy with the exception of adjuvant ET
  • Patient has had major surgery, chemotherapy or radiotherapy within 14 days prior to randomization
  • Patient has not recovered from clinical and laboratory acute toxicities related to prior anti-cancer therapies
  • Patient has a concurrent invasive malignancy or a prior invasive malignancy whose treatment was completed within 2 years before PICF signature
  • Patient has known HIV infection, Hepatitis B or C infection
  • Clinically significant, uncontrolled heart disease and/or cardiac repolarization abnormality
  • Patient is currently receiving any of the following substances within 7 days before randomization - Concomitant medications, herbal supplements, and/or fruits that are known as strong inhibitors or inducers of CYP3A4/5 or Medications that have a narrow therapeutic window and are predominantly metabolized through CYP3A4/5
  • is currently receiving or has received systemic corticosteroids ≤ 2 weeks prior to starting trial treatment
  • Patient has impairment of GI function or GI disease that may significantly alter the absorption of the oral trial treatments
  • Patient has any other concurrent severe and/or uncontrolled medical condition that would, in the Investigator's judgment, cause unacceptable safety risks, contraindicate patient participation in the clinical trial or compromise compliance with the protocol
