Clinical summary
Summary
This is an open-label, randomised trial with an experimental and active comparator arm. Participants in the Experimental arm will receive the selective oestrogen receptor degrader (SERD), Giredestrant. Giredestrant will be administered orally once per day on Days 1-28 of each 28-day cycle. Participants in the Active Comparator arm will receive the physician's choice of endocrine monotherapy (either Fulvestrant or an Aromatase inhibitor). In both Arms, participants who are premenopausal, perimenopausal or male will receive a luteinizing hormone-releasing hormone (LHRH) 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.
Conditions
This trial is treating people with breast cancer
Eligibility
Inclusion

- For women who are premenopausal or perimenopausal and for men: willing to undergo and maintain treatment with approved LHRH agonist therapy for the duration of study treatment
- Locally advanced or metastatic adenocarcinoma of the breast, not amenable to treatment with curative intent
- Documented ER-positive tumor and HER2-negative tumor, assessed locally
- Disease progression after treatment with one or two lines of systemic therapy (but not more than one prior targeted therapy) in the locally advanced or metastatic setting
- Measurable disease as defined per RECIST v.1.1 or bone only disease which must have at least one predominantly lytic bone lesion confirmed by CT or MRI which can be followed
- Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
- Adequate organ function
Exclusion
- Prior treatment with a selective estrogen receptor degrader (SERD), with the exception of fulvestrant, if fulvestrant treatment was terminated at least 28 days prior to randomization
