Eligibility
Key inclusion criteria
Inclusion criteria :

The percentage of participants without previous CDK 4/6 inhibitor will be capped to 20%. In the Chinese extension cohort, previous treatment with a CDK 4/6 inhibitor will not be mandatory, and there will be no limitation to the number of participants naïve to CDK4/6 inhibitor.
* Participants must present a secondary endocrine resistance to endocrine therapy defined as: progression while on endocrine therapy after at least 6 months of treatment for advanced breast cancer, or relapse while on adjuvant endocrine therapy but after the first 2 years, or with a relapse within 12 months after completing adjuvant endocrine therapy.
* Male or Female.

* Severe uncontrolled systemic disease at screening .
* Participants with known brain metastases that are untreated, symptomatic or require therapy to control symptoms.
* Prior treatment with mammalian target of rapamycin inhibitors or any other selective estrogen receptor degrader(SERD) compound, except fulvestrant if stopped for at least 3 months before randomization.
