- Participants who received adjuvant chemotherapy or no chemotherapy must have the following:
– No pathological involved nodes (pN0) and primary tumor larger than 1 cm, and must fulfill at least one of the features: Grade 3 or Ki67=20% or Oncotype DX =26 (if available) or High-Risk MammaPrint (if available)
or
– Pathological node-positive disease (microscopic and/or macroscopic tumor involvement, =pN1) and will be stratified in medium or high risk based on additional biological criteria: Grade, Ki67, Oncotype DX or MammaPrint
-Participants who received neoadjuvant chemotherapy must have residual disease in lymph nodes (=ypN1) after neoadjuvant chemotherapy.
- Participants with any pT primary tumor and pN2 or any pT primary tumor and pN3 or pT4 primary tumor and any pN.
- Participants who have documented ER+ (positive) tumor by immunohistochemistry, as assessed locally on a primary disease specimen and defined as = 1% of tumor cells stained positive according to the ASCO/College of American Pathologists (CAP) guidelines or European Society of Medical Oncology (ESMO) guidelines or any national guidelines with criteria conforming to ASCO/CAP or ESMO guidelines.
- Participants must have undergone definitive surgery of their primary breast tumor(s) and axillary lymph nodes (ALND and/or SLNB).
- Participants who received adjuvant chemotherapy must have completed adjuvant chemotherapy prior to randomization. Participants may also have received neoadjuvant chemotherapy. A washout period of at least 21 days is required between last adjuvant chemotherapy dose and randomization.
