Patients planned to receive at least 2 courses of chemotherapy regimens with FN high risk or Intermediate risk with other risk factors (including, but not limited to,≥65 years-old, poor nutritional/performance status i.e., ECOG score ≥2, etc.);
ECOG score 0-2;
Expected survival of not less than 12 weeks;
Neutrophil count (ANC) ≥ 2.0×109/L, hemoglobin (Hb) ≥90g/L and platelet (PLT) ≥80 × 109/L before enrollment;
Liver and kidney function meet the following criteria: total bilirubin ≤ 1.5 times the upper limit of normal, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 times the upper limit of normal, serum creatinine ≤ 1.5 times the upper limit of normal;
Left Ventricular Ejection Fractions≥50%;
Women of non-childbearing potential, i.e. women who have been postmenopausal for at least 1 year or have undergone sterilization surgery (bilateral tubal ligation, double oophorectomy or hysterectomy); Patients of childbearing potential agree to use adequate contraception within 1 month prior to the start of the trial and 30 days after the end of the study: condoms, spermicidal condoms, foams, gels, diaphragms, intrauterine devices (IUDs), contraceptives (administered orally or by injection).
