Evaluate the efficacy of elacestrant in combination with each of the other study drugs for ORR as per RECIST v. 1.1, DoR, CBR, PFS, and OS
Phase 2
Primary Objectives
Evaluate the efficacy of elacestrant in combination with each of the other drugs for PFS

Eligibility
Eligibility
Inclusion Criteria:
Patient has the signed informed consent form before any study-related activities according to local guidelines.
Women or men aged ≥18 years, at the time of informed consent signature.
Female patients may be either postmenopausal or premenopausal or perimenopausal. Postmenopausal status is defined by:
Age ≥60 years
Age <60 years and amenorrhea for 12 or more months (in the absence of chemotherapy, tamoxifen, toremifene, or ovarian suppression) or a follicle stimulating hormone (FSH) value >40 mIU/mL and an estradiol value <40 pg/mL (140 pmol/L) or in postmenopausal ranges per local reference ranges
Documentation of prior bilateral oophorectomy, at least 1 month before first dose of trial therapy).
Patient must have ER-positive, HER-2 negative tumor status as confirmed by local laboratory testing either from a fresh biopsy or from an archival tissue obtained no more than 2 years prior to signing of the informed consent form.
ER and HER-2 testing must be performed in the following manner:
Documentation of ER positive tumor with ≥ 1% staining by immunohistochemistry (IHC) as defined in the 2010 or 2020 American Society for Clinical Oncology (ASCO) recommendations for ER testing, with or without progesterone receptor (PGR) positivity
HER-2 negative tumor with an IHC result of 0 or 1+ for cellular membrane protein expression or an in situ hybridization negative result as defined in the 2013 or 2018 ASCO recommendations for HER-2 testing
Patients receiving concomitant corticosteroids must be on a stable or decreasing dose for at least 7 days prior to baseline and not receiving doses higher than 4 mg of dexamethasone per day or equivalent.
Any neurological symptoms of brain metastases must be stable for at least 2 weeks before starting trial therapy.
Patient has received prior therapy in the metastatic setting including:
At least one endocrine therapy
Up to two chemotherapy regimens
Up to two prior CDK 4/6 inhibitors, not including abemaciclib
If recurrence was observed while on adjuvant therapy or within 12 months of end of adjuvant therapy, this therapy will be counted as part of required prior therapy for eligibility.
Toxicity from prior therapy must be resolved to National Cancer Institute (NCI) CTCAE version 5.0 Grade ≤1, with the exception of alopecia and peripheral sensory neuropathy (Grade ≤2).
Patient has documented intra- and/or extra-cranial radiological progression or recurrence while on or after the most recent therapy.
Patient has an Eastern Cooperative Oncology Group (ECOG) performance status of ≤2
Patient has adequate bone marrow and organ function, as defined by the following laboratory values:
Absolute neutrophil count (ANC) ≥1.5 × 109/L
Platelets ≥100 × 109/L
Hemoglobin ≥9.0 g/dL
Potassium, sodium, calcium (corrected for serum albumin) and magnesium CTCAE Grade ≤1 (if screening assessments are abnormal, these assessments may be repeated up to 2 times; subjects may receive appropriate supplementation or treatment prior to reassessment)
Creatinine clearance (per Cockcroft-Gault formula) ≥50 mL/min
Serum albumin ≥3.0 g/dL (≥30 g/L)
In absence of liver metastases, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 × ULN. If the patient has liver metastases, ALT and AST ≤5 × ULN
Total serum bilirubin <1.5 × ULN except for patients with Gilbert's syndrome who may be included if the total serum bilirubin is ≤3.0 × ULN or direct bilirubin ≤ 1.5 × ULN
The patient is able and willing to adhere to the study visit schedule and other protocol requirements.
For Phase 1b, the presence of brain metastases is allowed but not required for eligibility. In Phase 2, patients must have at least one active and measurable brain metastasis per RECIST version 1.1
Any of the following qualifies brain metastases as active:
Newly diagnosed brain metastasis in patients who never received prior CNS-directed therapy.
Newly diagnosed brain metastasis outside any area that was previously subjected to CNS-directed therapy
Brain metastases that are progressing in an area that has previously been subjected to CNS-directed therapy
For lesions, including brain metastases, to qualify as measurable, and possibly be selected as target lesions, per RECIST version 1.1 (Appendix C), the longest diameter must be ≥10 mm by CT or magnetic resonance imaging (MRI).
Exclusion Criteria:
Immediate CNS-specific treatment is likely to be required, per the treating physician's assessment.
Patient has imminent organ failure and/or visceral crisis.
Patient has leptomeningeal metastases, defined as having positive CSF cytology or unequivocal radiologic or clinical evidence of leptomeningeal involvement.
Breast cancer treatment-naïve patients in the metastatic setting. Patients who experience a recurrence while on adjuvant therapy or within 12 months of end of adjuvant therapy are allowed.

Females who are breastfeeding or pregnant.
Known intolerance to either study drug or any of the excipients.
