Age<60 years but have natural menopause ≥ 12 months with estradiol (E2)and follicle stimulating hormone (FSH) levels in the postmenopausal range without chemical ablation(chemotherapy,toremifene, tamoxifen, or ovarian castration drugs). Premenopausal or perimenopausal concurrently given a luteinizing hormone-releasing hormone (LHRH) agonist starting before the start of trial therapy and is planned to continue LHRH agonist during the study. Subjects are willing to provide blood for Estrogen Receptor 1 (ESR1)mutation status analysis. The ECOG score is 0-1 and has not deteriorated in the past 2 weeks. Expected survival ≥ 3 months. Histologically or cytologically confirmed breast cancer. Latest primary or metastatic tumor biopsy confirmed positive for Estrogen Receptors (ER+) and negative for HER2 (HER2-) receptor (subject to local laboratory pathological test results). Prior therapy is restricted as follows: No more than 2 lines of chemotherapy for advanced/metastatic breast cance or cannot tolerate standard chemotherapy (if disease progression/recurrence occurs more than 12 months after the end of previous neoadjuvant/adjuvant chemotherapy, it will not be included in line 1 chemotherapy; otherwise, it will be included in line 1 chemotherapy). Prior to receiving standard endocrine therapy for at least 6 months or being unable to tolerate standard endocrine therapy (including selective estrogen receptor modulator (SERM) or aromatase inhibitors) for adjuvant therapy or advanced/metastatic diseases, and the disease progresses during endocrine therapy, Prior treatment with selective estrogen receptor degrade (SERD)is not allowed. Note:For Part A, There is no limit on the number of lines of prior endocrine therapies, and multiple lines of endocrine therapy are allowed; For Part B, Prior endocrine therapy must be combination therapy or sequential therapy of CDK4/6 and AI. At least one lesion (measurable and/or non-measurable, as per RECIST 1.1) Patients who planning to undergo 18F-FES PET-CT examination must have at least one measurable lesion located outside the bladder, small intestine and liver that meets RECIST v1.1 with a maximum diameter of ≥ 15mm.
