Open label, single arm, dose-escalation phase I study in ambulatory patients receiving first line chemotherapy for metastatic breast cancer. The treatment comprises of the standard 6 cycles of weekly paclitaxel (80 mg/m² IV at D1, D8 and D15 of a 28 day cycle) and two EOC202 doses (6 and 30 mg SC at D2 and D16 of a 28 day cycle) for 6 cycles. After completion of the combined therapy, the patients can continue to receive up to 6 cycles of EOC202 maintenance monotherapy (once every cycle on day 1 of each cycle).

The previous adjuvant chemotherapy, targeted therapy, antitumor traditional Chinese medicine or Chinese drug preparation, radiotherapy or surgery prior to the first dose must have been completed for at least 4 weeks, endocrine therapy must have been completed for at least 2 weeks; and all the relevant toxicities (except for alopecia and other adverse events that are judged by investigators as tolerable) have been recovered to grade 1 or normal level. 10. At least one measurable lesion as defined by RECISTV 1.1 evaluation criteria for solid tumors; 11. Good organ function level; 1) Hematology: total white blood cell count = 3x109/L; absolute neutrophil count (ANC) = LLN(lower limit of normal), platelet count = LLN, hemoglobin = 9g/dL; 2) Liver: serum total bilirubin = 1.5 upper limit of normal (ULN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT)= 3xULN(for patients with Gilbert syndrome, total bilirubin= 3xULN is allowed; for patients with hepatic metastasis , total bilirubin = 3xULN, AST and ALT= 5xULN are allowed); 3) Renal: serum creatinine = 1.5 x ULN. Exclusion Criteria: 1. Previous chemotherapy for metastatic breast cancer; 2. Patients with recurrence of breast cancer within 6 months after the last dose of previous adjuvant chemotherapy; 3. Inability to discontinue CYP isoenzyme inhibitor or inducer prohibited in the protocol 2 weeks before the first dose and during the trial; 4.

Clinically significant ECG abnormality, including but not limited to serious arrhythmia, prolonged QTc (QTcF=470ms, QTcF=QT/RR0.33), or existence of various factors that may increase the risk of prolonged QTc (hypokalemia, congenital long QT syndrome, or current use of any drug that is known to prolong QTc)); 7.

History of autoimmune disease, immunodeficiency disease or organ transplantation (including allogeneic bone marrow transplantation), or previous hematopoietic stem cell rescue following chemotherapy, or having active autoimmune disease, immunodeficiency disease, or the disease requiring systemic steroid hormone (>10mg daily prednisone or equivalent dose to 10mg prednisone) or immunomodulatory drug for continuous treatment; 9. Other malignant tumors other than breast cancer in the past three years (except successfully treated squamous cell carcinoma of the skin, superficial bladder cancer, and in situ carcinoma of the cervix); 10. Previous allergy to macromolecular protein preparation or protein, or Quincke's edema (also known as angioneurotic edema), or known allergy to any component of the investigational product, including cremophor EL; 11. History of clear mental disorder, or history of psychotropic drug abuse, drug addiction or alcohol abuse; 12. Vaccination with live attenuated vaccine within 4 weeks prior to the first dose of investigational product, or expected vaccination with live attenuated vaccine during the trial or within 3 months after the end of combined therapy; 13. Previous use of systemic immunomodulator prior to the first dose of investigational product, and discontinuation of the systemic immunomodulator = 5 half-lives of the drug at the first dose; 14. Receiving therapy in any other clinical trial within 4 weeks prior to the first dose of investigational product; 15. Patients who are judged by investigators as unsuitable to participate in the clinical trial as participation in the trial may increase the risk or there may be other severe, acute or chronic disease that may interfere with the interpretation of the trial results; 16. Patients who are not suitable to participate in the trial for other reasons, as judged by investigators. |
