Treatment: Drugs - Ribociclib
Treatment: Drugs - Letrozole
Treatment: Drugs - Ansastrozole
Treatment: Drugs - Goserelin
Treatment: Drugs - Leuprolide
Treatment: Drugs - Exemestane

Experimental: Ribociclib + endocrine therapy - Participants will receive ribociclib 400 mg orally once daily on days 1 to 21 of a 28-day cycle, in combination with daily endocrine therapy (ET) for 36 months (approximately 39 cycles). ET consists of:

* For postmenopausal women: letrozole 2.5 mg orally once daily continuously, anastrozole 1 mg orally once daily continuously, or exemestane 25 mg once daily continuously.
* For pre/perimenopausal women, and men: letrozole 2.5 mg orally once daily continuously, anastrozole 1 mg orally once daily continuously, or exemestane 25 mg once daily continuously, combined with goserelin subcutaneously (at 3.6 mg once every 4 weeks if the one-month depot formulation is used or at 10.8 mg once every 3 months if the three-month depot formulation is used) or leuprolide subcutaneously (at 3.75 mg once every 4 weeks if the one-month depot formulation is used or at 11.25 mg once every 3 months if the three-month depot formulation is used)

Ribociclib 400 mg orally once daily on days 1-21 of a 28 day cycle followed by 7 days rest

Treatment: Drugs: Letrozole
Letrozole 2.5 mg orally once daily continuously

Treatment: Drugs: Ansastrozole
Anastrozole 1 mg orally once daily continuously.

Treatment: Drugs: Goserelin

Eligibility
Key inclusion criteria
Key

* Participant has a histologically and/or cytologically confirmed diagnosis of estrogen-receptor positive and/or progesterone receptor positive breast cancer
* Participant has HER2-negative breast cancer

For participants with prior ET treatment > 12 months, the investigator should rule out disease recurrence prior to enrollment. The number of participants with prior ET between 12 and 36 months will be capped at 1000.
* Participant has no contraindication for the adjuvant ET in the study.
* Participant after complete surgical resection with the final surgical specimen microscopic margins free from tumor and in one of below categories:

* Anatomic Stage Group III
* Anatomic Stage Group II (subset)
* Anatomic Stage Group I (high-risk subset as exploratory cohort)
* Participant has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0,1 or 2.
* Participant has adequate bone marrow and organ function.
