Study Summary

Primary Objective: To determine whether amcenestrant per overall survival (os) improves progression free survival (PFS) when compared with an endocrine monotherapy of the choice of the physician, in participants with metastatic or locally advanced breast cancer Secondary Objectives: * To compare the overall survival in the 2 treatment arms * To assess the objective response rate in the 2 treatment arms * To evaluate the disease control rate in the 2 treatment arms * To evaluate the clinical benefit rate in the 2 treatment arms * To evaluate the duration of response in the 2 treatment arms * To evaluate the PFS according to the estrogen receptor 1 gene (ESR1) mutation status in the 2 treatment arms * To evaluate the pharmacokinetics of amcenestrant as single agent * To evaluate health-related quality of life in the 2 treatment arms * To compare the overall safety profile in the 2 treatment arms

Primary Outcome

PFS is defined as the time in months interval from the date of randomization to the date of first documented tumor progression as per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) assessed by independent central review (ICR) or death (due to any cause), whichever comes first. Progressive Disease (PD) as per RECIST 1.1: at least a 20 percent (%) increase in sum of diameters of target lesions, unequivocal progression of existing non-target lesions. Analysis was performed by Kaplan-Meie
