A phase IIIb study to characterize the efficacy and safety of Adjuvant ribociclib plus endocrine therapy in a close-to-clinical practice patient population with HR+ HER2- early breast cancer (Adjuvant WIDER)
The purpose of this open-label, multicenter, phase IIIb, single-arm study is to characterize the efficacy and safety of the combination of ribociclib and standard adjuvant endocrine therapy (ET) on invasive breast cancer-free survival (iBCFS), in a close to clinical practice patient population with HR-positive (HR+), HER2-negative (HER2-), Anatomic Stage Group III, IIB, and a subset of Stage IIA Early Breast Cancer (EBC).
