Brief summary

Progression-free survival using RECIST 1.1 criteria, as assessed by local radiologists/investigators

Detailed description

To compare the two treatment arms with respect to PFS2 in the HER2-E cohort, To compare the two treatment arms with respect to overall survival in the HER2-E cohort, To evaluate the two treatment arms with respect to ORR and clinical benefit rate (CBR) in HER2-E patients, where CBR, defined as percentage of patients with CR, PR per RECIST or SD lasting 24 weeks or longer., To evaluate the safety and tolerability of ribociclib and palbociclib in combination with endocrine therapy the HER2-E cohort, To evaluate patient reported outcomes for health-related quality of life in the two treatment arms of the HER2-E cohort., To describe time to response and duration of response in each treatment arm.
