Inclusion criteria

• {"criterion_text":"- Provide written, informed consent to participate in the study and follow the study procedures.\n- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.\n- Elapsed time from prior indication-based therapy to randomization: a. >14 days from any other prior endocrine therapy. b. ≥14 days from previous radiation therapy (28 days for brain lesions). c. >14 days or 5 half-life periods (whichever is shorter) from last dose of prior investigational anticancer drug therapy.\n- Female patients must meet 1 of the following criteria: a. Documented bilateral surgical oophorectomy. b. Aged ≥60 years with amenorrhea ≥1 year since last menses. c. Aged <60 years with serum estradiol and follicle stimulating hormone (FSH) levels within the laboratory reference range for post-menopausal women. d. Pre- or peri-menopausal female patients are eligible if amenable to treatment with a luteinizing hormone-releasing hormone (LHRH) agonist. Patients are to have commenced concomitant treatment with LHRH agonist prior to randomization and must be willing to continue it for the duration of the study.\n- Pre- and peri-menopausal female patients must have negative β-human chorionic gonadotropin (hCG) serum or urine pregnancy test prior to study entry, periodically for the duration of treatment, and at the EOT visit.\n- Pre- or peri-menopausal female patients must agree and commit to the use of a highly effective method of contraception from the time of informed consent until 6 months after the last dose of alisertib, and must agree to comply with contraception methods after the last dose of fulvestrant and tamoxifen (if applicable) for the duration specified in the approved product label. If the highly effective method cannot be used, using 2 other effective methods at the same time is required. a. Highly effective methods: Intra-uterine devices. b. Other effective methods (barrier methods): Latex condom, diaphragm with spermicide, cervical cap, sponge.\n- Male patients, even if surgically sterilized (i.e., status post-vasectomy), must agree and commit to using a highly effective method of contraception with their biologically female partner(s) of reproductive potential while on treatment and for 3 months after last dose of investigational product. If 1 of the highly effective methods cannot be used, patients must use 2 other effective methods at the same time. Male patients must refrain from donating sperm during the trial and for 3 months after last dose of investigational product. Male patients must receive concomitant treatment with gonadotropin releasing hormone (GnRH) analog. Patients are to have commenced concomitant treatment with GnRH analog prior to randomization and must be willing to continue it for the duration of the study. a. Highly effective methods: Intra-uterine devices, hormonal (birth control pills/oral contraceptives, injectable contraceptives, contraceptive patches, or contraceptive implants). b. Other effective methods (barrier methods): Latex condom, diaphragm with spermicide, cervical cap, sponge.\n- Adequate major organ and hematologic function as defined by the screening parameters below:\n- Aged ≥18 years at signing of informed consent.\n- Willing to provide tumor tissue for biomarker assessment. Note: Tumor tissue from a pre-treatment biopsy or from after the last known disease progression is required. If the biopsy procedure presents an unacceptable safety concern for the patient as determined by the Investigator, or other exceptional reason upon agreement with the Sponsor, archival formalin-fixed paraffin-embedded (FFPE) tissue from the recurrent or metastatic tumor may be submitted.\n- Pathology-confirmed diagnosis of adenocarcinoma of the breast with evidence of recurrent or metastatic disease not amenable to curative therapy.\n- Progression on or after treatment with at least 2 prior lines of endocrine therapy in the recurrent or metastatic setting. a. If metastatic disease recurrence occurs during or within 6 months of discontinuing adjuvant endocrine therapy, then that endocrine therapy will count as one line of prior therapy.\n- Patients must have received a CDK4/6i in combination with endocrine therapy in the recurrent or metastatic setting. a. If metastatic disease recurrence occurs during or within 6 months of discontinuing adjuvant CDK4/6i therapy in combination with endocrine, then the adjuvant CDK4/6i will count as the required CDK4/6i.\n- HR+ and HER2- tumor status reported per local laboratory testing. HR and HER2 testing must be performed consistent with current American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) or European Society of Medical Oncology (ESMO) guidelines: a. HR+ disease defined as ≥1% estrogen receptor (ER) positive and/or progesterone receptor (PgR) positive cells. b. HER2- tumor with an immunohistochemistry (IHC) result of 0 or 1+ for cellular membrane protein expression or 2+ with a negative in-situ hybridization result.\n- At least one measurable target lesion as defined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). Note: Lytic bone lesions or mixed lytic-blastic bone lesions with identifiable soft tissue components that can be evaluated by cross sectional imaging techniques, such as CT or MRI, can be considered as measurable lesions if the soft tissue component meets the definition of measurability according to RECIST v1.1.\n- Must be an appropriate candidate for Investigator-selected endocrine therapy and treatment naïve to Investigator-selected endocrine therapy in the recurrent or metastatic setting. Note: The Investigator may select an endocrine therapy the patient received in the adjuvant setting if the patient did not have a recurrence while receiving the selected endocrine therapy."}

Exclusion criteria

• {"criterion_text":"- Treatment with chemotherapy in the recurrent or metastatic setting.\n- Patients with bone only disease presenting with only blastic bone lesions or only lytic/mixed lytic-blastic bone lesions that do not meet the definition of measurability according to RECIST v1.1\n- Major surgery within 28 days before randomization (major according to the Investigator’s and/or Medical Monitor’s assessment).\n- Prior treatment with an Aurora Kinase A (AURKA) specific-targeted or pan-Auroratargeted agent, including alisertib, in any setting.\n- Any active infection requiring systemic treatment (antibacterial, antiviral, or antifungal) within 7 days of randomization.\n- Immunocompromised patients, including: a. Known active Human Immunodeficiency Virus (HIV) infection as determined by HIV ribonucleic acid (RNA) viral load and CD4 count. b.
