Trial Information

A Multi-institutional, Open-label, Single Arm Study of Apatinib in Non-triple-negative Metastatic Breast Cancer

Apatinib is a tyrosine kinase inhibitor targeting vascular endothelial growth factor
receptor (VEGFR), and its anti-angiogenesis effect has been viewed in preclinical tests. The
investigators' phase I study has shown that the drug's toxicity is manageable and the
maximum tolerable daily dose is 850 mg. The hypothesis of this clinical research study is to
discover if the study drug apatinib can shrink or slow the growth of non-triple-negative
breast cancer. The safety of apatinib will also be studied. Patients physical state,
symptoms, changes in the size of the tumor, and laboratory findings obtained while on-study
will help the research team decide if apatinib is safe and effective in pretreated
non-triple-negative metastatic breast cancer patients.

Inclusion Criteria:

●≥ 18 and ≤ 70 years of age.

- ECOG performance status of 0-1.

- Metastatic breast cancer, confirmed by histological analysis.

- Have experienced at least 1 and at most 4 regimens, and failed from the last
chemotherapy regimen. Pretreated anthracycline, taxanes and capecitabine (any
rational reason for no use of capecitabine is acceptable) are mandatory.

- Women diagnosed with human epidermal growth factor receptor positive (HER2+) should
have failed for at least 1 anti-HER2 therapy (any rational reason for no use of
anti-HER2 therapy is acceptable). HER2+ is defined as +++ staining on
immunohistochemistry or FISH/CISH positive for gene amplification.

- Women diagnosed with HR+ should have failed for at least 1 hormonal therapy.

- Have failed for at least one chemotherapy regimen, but at most three
regimens(including adjuvant and neo-adjuvant setting).

- Duration from the last therapy (chemotherapy, radiotherapy, target therapy and
operation) is more than 4 weeks (Duration for nitroso or mitomycin is 6 weeks).

- Have at least one extracranial measurable site of disease according to RECIST 1.0
criteria that has not been previously irradiated.

- Life expectancy of more than 3 months.

- Negative serum or urine pregnancy test taken in all women within 7 days before
inclusion. Sexually active women of childbearing potential must use a medically
acceptable form of contraception from the beginning of the study to 8 weeks after the
last dose of the investigated drug.

- Written informed consent prior to study specific screening procedures.

Exclusion Criteria:

- Triple-negative breast cancer (ER-, PR- and HER2-. HER2- is defined as 0 or 1+
staining on immunohistochemistry or FISH/CISH negative for gene amplification. )

- Pregnant or lactating women.

- Less than 4 weeks from the last clinical trial.

- Uncontrolled hypertension with mono-drug therapy (>140/90 mm Hg);ischemia of the
myocardium (≥ grade 2) or myocardial infarction;arrhythmia(≥ grade 2, QTcF > 470ms
for female patients) or New York Heart Association Class III/IV

- Any factors that influence the usage of oral administration.

- The cumulative doses of doxorubicin and epirubicin before inclusion have surpassed
300 mg/m2 and 600 mg/m2, respectively.

- Duration from the last therapy (chemotherapy, radiotherapy, target therapy and
operation) is less than 4 weeks (Duration for nitroso or mitomycin is less than 6

- Confirmed brain metastasis.

- Inadequate hepatic, renal, heart, and hematologic functions (hemoglobin <90g/L,
neutrophils < 1.5×10^9/L, platelets < 80×10^9/L , ALT > 2.5 x upper limit of normal
(ULN)(5x for liver metastasis), AST > 2.5 x ULN (5x for liver metastasis), serum
bilirubin > 1.5 x ULN, serum creatine > 1.0 x ULN, creatinine clearance rate ≤
50ml/min, LVEF < lower limit of normal (LLN).

- Abnormal coagulative function, inclined to bleeding or is receiving
thrombolytictherapy or anticoagulation.

- History of arterial/venous embolic events (such as cerebrovascular accident, TIA,
deep vein thrombus,and pulmonary embolism)

- Unhealed wound (> 30 days) or bone fracture.

- Urine protein ≥++ and confirmed >1.0 g by the 24h quantity.

- Previous or present history of pulmonary fibrosis,interstitial
pneumonia,pneumoconiosis,radiation pneumonitis,drug-related pneumonitis or
greatly-impaired pulmonary function.

- Disability of serious uncontrolled intercurrence infection.

- Abuse of alcohol or drugs.

- Have received prior treatment with a VEGFR, PDGFR or s-SRC TKI (Bevacizumab is

- Acquired or inherent immunodeficiency; HIV infection; organ transplantation history.

- The active HBV or HCV infection or HBV DNA ≥10^4/ml.

- History of other malignancies except cured basal cell carcinoma of skin and carcinoma
in-situ of uterine cervix.

- Presence of serious harm to subjects or complication to hinder the completion of the
study judged by investigators
