Arm Intervention/treatment
Experimental: SCT200
Initially, 6.0mg/kg of SCT200 will be administered once a week for a maximum of 6 cycles. After 6 cycles, 8.0mg/kg of SCT200 will be administered every two weeks until disease progression.
Biological: SCT200
Recombinant Anti-EGFR Monoclonal Antibody(SCT200)

Primary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: 1 year ]
    ORR is defined as proportion of patients achieving complete response (CR) or partial response (PR) according to RECIST v1.1 during trial treatment.

Secondary Outcome Measures :
  1. Adverse events (AEs) [ Time Frame: 1 year ]
    AE are assessed according to NCI CTCAE v4.03.

  2. Progress Free Survival ( PFS) [ Time Frame: 1 year ]
    PFS is defined as the time from first dose of SCT200 until the date of first documentation of progression or date of death, whichever occurs first,according to RECIST v1.1 criteria.

  3. Duration of response (DOR) [ Time Frame: 1 year ]
    DOR is defined as time from the date when a patient first meets the criteria for CR or PR according to RECIST v1.1, until the date that progressive disease (PD) is objectively documented or death, whichever occurs first.

  4. Disease control rate (DCR) [ Time Frame: 1 year ]
    The achievement of any a stable response(SD), partial response (PR) or complete response (CR), according to RECIST v1.1 criteria.

  5. Time to Progression (TTP) [ Time Frame: 1 year ]
    TTP is defined as the time from first dose of SCT200 until the date of first documentation of progressive disease (PD), according to RECIST v1.1 criteria.

  6. Overall survival (OS) [ Time Frame: 1 year ]
    OS is defined as time from first dose of SCT200 until the date of death from any cause.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Gender Based Eligibility:   Yes
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Able to provide written informed consent and can understand and comply with the requirements of the study;
  • Women from 18 to 75 years old;
  • Life expectancy of longer than 3 months ( clinical assessment);
  • With an Eastern Cooperative Oncology Group (ECOG) performance status 0-2;
  • Histological or cytological diagnosis of relapsed/metastatic triple receptor negative breast cancer (TNBC).TNBC is defined negatively expression of estrogen(ER), progesterone(PR) and human epidermal receptor-2(HER2).If there is a pathology report of the metastasis, take the histopathology of the metastases as standard. Negative of ER and PR is defined as expression of ER,PR<1% of the tumor cells by immunohistochemistry (IHC). HER2-negative is defined as a score of 0 and 1+ by IHC, or IHC 2+ & fluorescent in situ hybridization (FISH)negative. If the ER2 test result is 0 or 1+ by IHC, FISH detection is optional, but the result must be negative.
  • Participants has received prior anthracyclines and/or taxanes in first-line therapy. Disease progressed after latest chemotherapy. For adjuvant therapy/neoadjuvant therapy, disease relapse or progression during treatment or within 6 months after treatment is considered as failure of standard therapy.
  • According to RECIST 1.1 , patients must have at least one measurable lesion that can be accurately assessed at baseline.
  • Adequate organ and marrow function as defined below:

Absolute neutrophil count (ANC) greater than/equal to 1.5×l09/L; Platelets greater than/equal to 75×109/L; Hemoglobin greater than/equal to 80g/L; Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) less than/equal to 3 times ULN, or less than/equal to 5 times ULN if known liver metastases; Total bilirubin less than/equal to 1.5 within institutional limit of normal (ULN); Serum creatinine less than/equal to 1.5 times ULN; Electrolyte: magnesium greater than/equal to normal.

-Females: Post-menopausal, surgically sterile, non-pregnant and non-lactating.Women of childbearing potential must not be pregnant as assessed by a negative serum beta HCG test drawn upon admission to the hospital or up to 7 days prior to admission, and must agree to use adequate contraception (Oral contraceptives; intrauterine deviceshormonal; barrier method of birth control; abstinence) for the duration of study participation.and within 6 months after study.

  • Subject receiving bisphosphonate or denosumab treatment for bone metastases was initiated within 28 days prior to study. (If the subject has received bisphosphonate or denosumab treatment prior to study and showing stable time less than 28 days,the subject is allowed to use it. Subjects who were enrolled in this study may start taking bisphosphonate or denosumab for bone metastases after the first assessment of the efficacy.

  • Patients are currently enrolled in other research devices or in research drugs, or less than 4 weeks from other research drugs or devices.
  • Patients received major surgery(such as need general anesthesia ) within 4 weeks , should recover from the injury associated with the surgery.
  • Patients treated with EPO, G-CSF or GM-CSF.
  • Patients who have clinically significant cardiovascular disease (defined as unstable angina pectoris, symptomatic congestive heart failure (NYHA, greater than II), uncontrollable severe arrhythmia); Patients occurred myocardial infarction within 6 months.
  • According to the investigator's judgment, patients have other coexisting severe and/or poorly controlled medical conditions (such as uncontrolled hypertension, uncontrolled diabetes, clotting/hemorrhagic disease, etc.).

  • Patients with clinical symptoms, required clinical intervention or stable time less than 4 weeks of serous cavity effusion (such as pleural effusion and ascites);
  • Patients with serious psychological or psychiatric disorders which may affect subject compliance in this clinical study;
  • Pregnant or lactating women, or women who planned to be pregnant within 6 months of treatment;
  • Patients who were not willing to accept effective contraceptive measures (including male or female subjects) during treatment and within 6 months after treatment;
  • Patients with active hepatitis B or active hepatitis C, etc. (for patients with a history of hepatitis B, whether treated or not, HBV DNA ≥104 or ≥ 2000IU/ml, HCV RNA≥15IU/ml); HIV antibody positive (if there is no clinical evidence suggesting that there may be HIV infection, there is no need to detect);
