You may qualify if…

Postmenopausal/premenopausal women aged ≥18 years and ≤70 years;
HR + / HER2 breast cancer confirmed by histology (note: her2-negative is defined as: (1) IHC1 + / IHC0; ②IHC2+ : FISH-);
Confirmed by the histology of locally advanced breast cancer (local treatment) to radical or recurrent metastatic breast cancer;
In the late stage of untreated or experienced a CDK4/6 with endocrine therapy of patients;
Researchers think that for selecting patients with chemotherapy (step 2022 guidelines recommend for internal transfer, always endocrine therapy resistance or preferred to rescue patients with endocrine therapy best choice of chemotherapy);
One line finish cycle disease after chemotherapy (4 to 8 cycles) to alleviate or stable, quasi follow-up maintenance treatment: a. late stage A gleam of unused CDK4/6 inhibitors + endocrine group subjects into the queue for A; b. Used in the late phase line CDK4/6 inhibitors queue B + endocrine subjects into groups;
Into the former group at least one measurable lesions (RECIST v1.1 standard); 8.ECOG score 0 to 2 points;
Always all the acute toxic reaction caused by antineoplastic therapy in screening before easing to 0 and 1 level (according to the NCI CTCAE 5.0 judgment; Hair loss, other than toxicity that the investigator believes does not pose a safety risk to the subject); 10. Functions: bone marrow neutrophils absolute acuity 1.5 x 109 / L, platelet acuity 100 x 109 / L, 90 g/L or higher hemoglobin; 11. Liver and kidney function: TBIL acuities were 1.5 x ULN; ALT and AST≤2.5 x ULN; In case of liver metastasis, ALT and AST≤ 5×ULN; BUN and Cr≤1.5×ULN and creatinine clearance ≥50 ml/min; 12.Voluntary participation in the clinical trials, signed written informed consent.

You may not qualify if…

Factors that significantly affect oral drug absorption, such as inability to swallow, chronic diarrhea, and intestinal obstruction;
Always received HDACi anti-tumor treatment;
This scheme known drug components have allergy history;
Always with other malignant tumours within five years, not including has cured thyroid papillary carcinoma, cervical carcinoma in situ, basal cell carcinoma or skin squamous cell carcinoma of the skin;
Within 4 weeks before into the group participated in other clinical trials;
A history of immune deficiency, including test positive for HIV, or has other acquired, congenital immunodeficiency disease, or has a history of organ transplantation;
Unable to control the important cardiovascular disease: a history of clinical significance of long QT, stage or screen between QTc > 450 ms; Severe cardiovascular injury (greater than a New York Heart Association (NYHA) Class II history of congestive heart failure), unstable angina or myocardial infarction within the last 6 months, or severe arrhythmia;
Pregnancy and lactation women patients or in infertile women baseline pregnancy test positive; Or participants of childbearing age who were unwilling to use effective contraception during the study period and for at least 8 weeks after the last dosing;
According to the researcher's judgment, there is serious to endanger the safety of patients, the patients completed studies or associated with disease (such as severe hypertension, diabetes, thyroid disease, active infection, etc.);
Always have a clear history of neurological or psychiatric disorders, including epilepsy or dementia, etc.;
Reference: subjects had active hepatitis (hepatitis b positive HBsAg and HBV DNA of 500 IU/ml or more; Hepatitis C reference: HCV antibody positive and HCV virus copy number > upper limit of normal);
The researchers determine doesn't fit to the researchers.
