What this Trial Is About

The objective of the study is to evaluate the efficacy and the safety of abemaciclib and giredestrant before surgery in participants with early stage, oestrogen receptor-positive (ER+), human epidermal receptor 2 negative (HER2-) breast cancer (BC). Primary objective: ● To evaluate the efficacy of abemaciclib and giredestrant in complete cell cycle arrest (CCCA) rate at Week 2. Secondary objectives: * To evaluate the efficacy of abemaciclib and giredestrant in reducing the relative Ki67 expression from baseline to Week 2 * To evaluate the efficacy of abemaciclib and giredestrant in risk of recurrence (ROR) score reduction, clinical and radiological tumor response; * To evaluate the safety of abemaciclib and giredestrant. Exploratory objectives: * To evaluate the mechanisms of response and resistance to therapy; * To evaluate the correlation between Ki-67% reduction and 18- Fluorothymidine (FLT) uptake reduction; * To evaluate the pathological complete response (pCR) rate (ypT0/is, ypN0) of giredestrant plus abemaciclib
