Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Giredestrant
Treatment: Drugs - Fulvestrant or an Aromatase Inhibitor (Physician Choice)
Treatment: Drugs - LHRH Agonist

Experimental: Giredestrant -

Active comparator: Physician Choice of Endocrine Monotherapy - The physician choice of endocrine monotherapy will be limited to fulvestrant or an aromatase inhibitor.


Treatment: Drugs: Giredestrant
Giredestrant is taken orally once per day on Days 1-28 of each 28-day cycle.

Treatment: Drugs: Fulvestrant or an Aromatase Inhibitor (Physician Choice)
Physician choice of endocrine monotherapy (fulvestrant or an aromatase inhibitor) is taken in accordance with the local prescribing information for the respective product.

Treatment: Drugs: LHRH Agonist
Only premenopausal/perimenopausal participants and male participants will receive a luteinizing hormone-releasing hormone (LHRH) agonist on Day 1 of each 28-day treatment cycle. The investigator will determine and supply the appropriate LHRH agonist locally approved for use in breast cancer.

Summary
Brief summary
This Phase II, randomized, open-label, multicenter study will evaluate the efficacy and safety of giredestrant compared with physician's choice of endocrine monotherapy in participants with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer who have received one or two prior lines of systemic therapy in the locally advanced or metastatic setting.
