Brief summary: The objective of this study is to explore and evaluate the efficacy of tucidinostat combined with metronomic capecitabine in the treatment of metastatic triple-negative breast cancer.


Eligibility criteria: Inclusion Criteria:

1. ≥18 years old, female; 2. Histologically confirmed triple-negative metastatic breast cancer \[HER2 negative is defined as immunohistochemistry(IHC) 0 or IHC 1+, and if the score of IHC is 2+, fluorescence in situ hybridization technology (FISH) test must be negative, subjects with ER ≤ 10% and PR ≤ 10% and those with no benefit from endocrine therapy in the investigator's judgment are allowed to enroll\]; 3. Metastatic breast cancer that has failed at first-line taxane therapy; definition of taxane treatment failure: disease progression during rescue therapy, or recurrence and metastasis within 12 months after completion of adjuvant therapy; 4. ECOG score 0-1; 5. According to RECIST1.1 criteria, at least there is one measurable lesion； 6. The main organ and bone marrow function levels meet the following requirements:

1. Blood routine: neutrophil (ANC) ≥ 1.5×109/L; platelet count (PLT) ≥ 90× 109/L; hemoglobin (Hb) ≥ 90g/L; It is required that no blood products (including red blood cells and platelet products, etc.) have been transfused and no growth factors (including colony-stimulating factor, interleukin, and erythropoietin, etc.) have been used for supportive treatment within 2 weeks before the examination.
2. Liver function: serum total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN (with liver Requirements for metastatic patients: ALT and AST≤5×ULN);
3. Renal function: serum creatinine (Cr)≤1.5×ULN or creatinine clearance rate\>60mL/min; 7. Expected survival time ≥ 3 months; 8. Voluntary participation study, signed written informed consent.

3. Received palliative radiotherapy for target lesion within 4 weeks before enrollment;
4. Previously received treatment with histone deacetylase inhibitors，or have previously received fluoropicidine drugs such as capecitabine and stopped drugs due to progress (if it is used in the adjuvant phase, then the progress of the treatment within 1 year after the suspension of the drug was stopped, and the group cannot be admitted to the study).

8. Patients with currently symptomatic brain or meningeal metastasis;
9. Received immunosuppressive drugs within 4 weeks before enrollment, excluding nasal spray, inhalation or other local glucocorticoids or physiological doses systemic glucocorticoids (no more than 10 mg/day of prednisone or other glucocorticoids at an equivalent dose), or use of glucocorticoids for the prevention of contrast medium allergy;
