Eligibility Criteria:
Inclusion Criteria:
* Voluntarily agree to participate in the study and sign the informed consent;
* Subjects aged 18-70 years (including 18 years and 70 years) and not reaching the 71st birthday were all considered to be ≤70 years old;
* Expected survival ≥12 weeks;
* Eastern Cooperative Oncology Group(ECOG) physical condition 0 or 1;
* For female subjects of child-bearing age women agreed to study during treatment and experimental subjects within 6 months after the end of the treatment period using an approved by the medical contraception (e.g. intrauterine device, the pill or condoms), before the study drug delivery within 7 days of pregnancy blood test must be negative (sterilization surgery or age 60 or more subjects can choose no pregnancy blood test), and must be an lactation. For male subjects: should be sterilized surgically, or agree to use a medically approved contraceptive method during the study period and for 6 months after the end of the treatment period. Control subjects after the end of the treatment period according to the choice of control drugs to determine the length of contraception.
* Able to understand the study requirements and be willing and able to follow the study and follow-up procedures.
* Bone marrow function:
hemoglobin ≥9g/dL; absolute neutrophil count ≥1.5×109/L; white blood cell count ≥3.0×109/L platelet ≥100 ×109/L;
* Liver function (according to the normal value of the clinical trial center) :
serum total bilirubin ≤1.5 times the upper limit of normal value (ULN); alanine aminotransferase (ALT), aspartate aminotransferase(AST) and Alkaline phosphatase（ALP） were ≤2.5 × ULN in the absence of liver metastasis, and ALT, AST and Alkaline phosphatase(ALP) were ≤5 × ULN in the presence of liver metastasis
* Renal function (according to the normal value of the clinical trial center) :
serum creatinine ≤1.5×ULN, or calculated by Cockcroft-Gault formula, the creatinine clearance rate (CrCl) ≥60 mL/min;
* Cardiac function:
American New York college of cardiology (NYHA) grade \< 3; left ventricular ejection fraction ≥50%;
* Breast cancer subjects diagnosed by histology and / or cytology are currently at a locally advanced or metastatic stage and cannot be radically removed;
* The low expression of HER2 confirmed by the IHC and FISH results of the central laboratory (defined as: IHC 2+ and no amplification of FISH); the subject can provide a specimen of the primary or metastatic tumor site (paraffin wax) for HER2 detection Block, paraffin-embedded section or fresh tissue section can be used);
* Previous use of anthracycline drugs;
* Received 1 or 2 systemic chemotherapy treatments after relapse / metastasis. Subjects who relapsed during adjuvant chemotherapy or within 12 months after the end of adjuvant chemotherapy were considered to have failed first-line chemotherapy after relapse / metastasis.

Patients who are not suitable for endocrine therapy can be included in this study after undergoing chemotherapy treatment (first-line or second-line);
* The imaging evidence confirmed by the investigator that the tumor disease progressed during or after the most recent treatment is required;

Exclusion Criteria:

* The research drug was used within 4 weeks before the start of study administration;
* Have undergone major surgery within 4 weeks before the start of study administration;
* Have received a live vaccine within 4 weeks before the start of study administration or plan to receive any vaccine during the study period;
* Serious cardiovascular and cerebrovascular events occurred within 12 months, including but not limited to unstable angina, myocardial infarction, cerebral hemorrhage, and cerebral infarction (except for asymptomatic and untreated lacunar infarction)；

* Suffering from active infection requiring systemic treatment;
* Have active autoimmune diseases (such as the use of corticosteroids or immunosuppressive drugs, etc.) that require systemic treatment within the past 2 years, allowing related alternative treatments (such as thyroxine, insulin, or the physiology of adrenal or pituitary insufficiency Corticosteroid replacement therapy);
* The toxicity of the previous anti-tumor therapy has not been restored to the 0 to 1 level defined by CTCAE version 5.0, of which the neurotoxicity has not been restored to 0; except for hair loss, pigmentation or other researches that do not increase the risk of medication Happening;
* Have a clear past or current history of neurological or mental disorders, including epilepsy or dementia;
* According to the investigator's judgment, there are concomitant diseases that seriously endanger the safety of the subject or affect the completion of the clinical study；
* Positive HIV test results; patients with active hepatitis B or C (HBsAg positive and hepatitis B virus（HBV） DNA titers above the upper limit of normal; Hepatitis C Virus Antibody(HCVAb) positive hepatitis C virus （HCV） RNA titers above the upper limit of normal)；
