Eligibility Criteria
Inclusion Criteria:

Patient has signed the informed consent before all study specific activities are conducted.

Women or men aged ≥18 years (or the minimum age of consent in accordance with the local law), at the time of informed consent signature. Female patients may be of any menopausal status.

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 surgical sterilization (i.e., bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, at least 1 month before first dose of trial therapy).
Premenopausal and perimenopausal women (who do not fit postmenopausal criteria) and men must be concurrently receiving a luteinizing hormone-releasing hormone (LHRH) agonist initiated at least 4 weeks before the start of trial therapy and are planning to continue LHRH agonist treatment during the study treatment.
For perimenopausal women to be considered of non-childbearing potential, FSH levels must be >40 mIU/ml.
Histopathological or cytological confirmed ER+, HER2-, breast cancer, per local laboratory, as per the American Society of Clinical Oncology (ASCO)/College of American Pathologists(CAP) guidelines (Allison et al, 2020, Wolff et al, 2018). Note: In the context of this trial, ER status will be considered positive if ≥10% of tumor cells demonstrate positive nuclear staining by immunohistochemistry, with or without PGR positivity. .
At least 1 not previously irradiated measurable lesion as per RECIST version 1.1 and/or at least 1 lytic or mixed (lytic +sclerotic) bone lesion with identifiable soft tissue components meeting the definition of measurability by RECIST version 1.1 that can be evaluated by CT or MRI; patients with sclerotic/osteoblastic bone lesions only in the absence of measurable disease are not eligible.
ECOG performance status of 0 or 1.

Patient has adequate bone marrow and organ function, as defined by the following laboratory values:

Absolute neutrophil count (ANC) ≥1.5 × 10^9/L
Platelets ≥100 × 10^9/L
Hemoglobin ≥9.0 g/dL
Potassium, sodium, calcium (corrected for serum albumin) and magnesium CTCAE grade ≤1

Creatinine is ≤ 1.5 x ULN or if creatinine is > 1.5 x ULN, then creatinine clearance must be ≥50 mL/min based on the Cockcroft-Gault formula. Note: C-G formula:

Creatinine clearance (male) = ([140-age in years] × weight in kg)/ ([serum creatinine in mg/dL] × 72)
Creatinine clearance (female) = (0.85 × [140-age in years] × weight in kg)/ ([serum creatinine in mg/dL] × 72)
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

Note: Patients with stable brain or subdural metastases are allowed if the patient has completed local therapy and was on a stable or decreasing dose of corticosteroids at baseline for management of brain metastasis for at least 4 weeks before starting treatment in this study. The dose must be ≤2.0 mg/day of dexamethasone or equivalent. Any signs (e.g., radiologic) or symptoms of brain metastases must be stable for at least 4 weeks before starting study treatment.

Prior treatment with fulvestrant is not exclusionary as it is an approved medication.
Patient has a concurrent malignancy or history of invasive malignancy within 3 years of enrollment, except basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix that has completed curative therapy. Other malignancies with low risk of recurrence may be considered eligible with Sponsor approval.

Detailed Description
This is a multicenter, Phase 1b/2 trial. The Phase 1b aims at selecting the RP2D dose, defined as a dose that is associated with less than 33% of patients experiencing a DLT of elacestrant when administered in combination with alpelisib, everolimus, palbociclib, abemaciclib, and ribociclib, that is, ≤1 patient experiencing a DLT out of 6 DLT evaluable patients. For each combination, this phase will have between 1 and 3 cohorts of 6 DLT-evaluable patients each. The total number of DLT-evaluable patients in all the combinations will vary between 24 and 72.

The Phase 2 part of the trial will evaluate the efficacy and safety of the various combinations in patients with ER+/HER2- advanced/metastatic breast cancer.

The treatment arms will be:

Arm A: 50 patients: elacestrant with alpelisib;
Arm B: 50 patients: elacestrant with everolimus;
Arm C: 60 patients (30 patients in each combination): elacestrant with either abemaciclib or ribociclib;
Arm D: 90 patients (30 patients in each combination): elacestrant with either palbociclib, abemaciclib, or ribociclib
Arm E: 60 patients: elacestrant with capivasertib

Phase 1b will have a total of 90 patients, while Phase 2 will have 310 patients for all treatment arm combinations.
