Summary
Brief summary (as posted)
Triple-negative breast cancer has always been a difficult problem in clinical practice because of its young onset age, high aggressiveness, no clear therapeutic target and poor clinical prognosis. The treatment of triple-negative breast cancer is mainly chemotherapy, and in order to break the current dilemma, new treatments must be introduced. Immunotherapy is one of the most high-profile treatments. The KEYNOTE-522 study and Impassion 031 Study have found that immunotherapy can significantly improve the pCR of patients with triple yin breast cancer, rate, independent of PD-L1 expression status, and good safety.Cedardenamine is a histone deacetylation (HDAC) inhibitor developed in China.Many studies suggest that the use of sidabamine will likely enhance the efficacy of PD-1 / PD-L1 mAb in breast cancer and expand the use of PD-1 / PD-L1 mAb in the beneficiary population of breast cancer

5.The patients refuse prior surgical treatment (the patient requires breast preservation, but it cannot be performed by surgical consultation), or it is not suitable for prior surgical treatment.
6.The main organ function is normal, that is, to meet the following criteria:
1. the criteria for blood routine examination:
1. ANC≥1.5×109/L；
2. PLT≥100×109/L；
3. Hb≥90g/L；
2. the criteria for biochemical examination:
1. TBIL\<1.5×ULN；
2. ALT and AST\<2.5×ULN；
3. BUN and Cr ≤ 1.5 × ULN or endogenous creatinine clearance rate ≥ 50ml/min (Cockcroft-Gault formula).
7.No malabsorption or other gastrointestinal disorders that affect drug absorption 8.Serum pregnancy tests for women of childbearing age must be negative within 7 days before treatment; all enrolled patients (whether male or female) should have adequate barrier contraception throughout the treatment period and within 4 weeks of treatment.
9.The subjects volunteer to join the study and sign informed consent, with good compliance and cooperated with follow-up.
Exclusion Criteria:
1. Previous use of investigational drugs such as PD-1 or PD-L1 mAb; sidabamine or other HDAC inhibitors, and taxane-based chemotherapies (including paclitaxel or docetaxel).
2. Distant metastases, but enrollment could be considered if the distant metastatic lesion is confined to the ipsilateral cervical lymph exclusion criteria node only.
3. Unstable systemic disease (including active infection, poorly controlled hypertension, unstable angina pectoris, congestive heart failure, hepatic, renal, or metabolic disease, etc).
4. Any other malignancy within five years (except completely cured cervical carcinoma in situ or basal or squamous epithelial skin carcinoma).
5. For known human immunodeficiency virus (HIV) infection, hepatitis B virus carriers must be treated for anti-hepatitis B virus replication during antitumor therapy.
6. Prior history of clear neurological or psychiatric disorders, including epilepsy or dementia.
7. Pregnant or lactating women.
8. Any unstable or potentially jeopardizing patient safety and its compliance to the study.
