- Prior bone marrow or stem cell transplant;
- With other malignant tumors other than breast cancer;
- Patients who have received a treatment with recombinant human granulocyte colony stimulating factor within 6 weeks prior to randomization;
- Diagnosed with acute congestive heart failure, cardiomyopathy, or myocardial infarction by clinical diagnosis, ECG or other approaches;
- With any disease that may cause splenomegaly;
- With acute infection, chronic active Hepatitis B within 1 year (unless patients tested negative for HBsAg prior to enrollment), or Hepatitis C;
- Women in pregnancy or breastfeeding;
- Known HIV positive or AIDS;
- With active tuberculosis (TB); history of TB exposure, unless negative for tuberculin test; TB patients undergoing treatment; or suspected TB evaluated by chest x-ray;
- With sickle cell anemia;
- With alcohol or drug abuse that may affect the compliance with the study;
- With known hypersensitivity to granulocyte colony stimulating factor or excipients;
- Have received any other investigational drug within 1 month or 5 half-lives of the investigational drugs prior to enrollment (whichever is longer);
- Patients with diseases or symptoms unsuitable for participating in the trial. For example, the study drugs may compromise the health of the patient or the assessment of adverse events may be affected.
