Fusion Protein rHSA/GCSFclinical Study on Breast Cancer Patients
Fusion Protein rHSA/GCSFclinical Study on Breast Cancer Patients
The purpose of this study is to evaluate the tolerance and safety of the rHSA/GCSF in breast
 cancer patients with different doses and multiple injections.

 To observe the pharmacokinetic characteristics of recombinant human serum albumin
 /granulocyte colony-stimulating factor fusion protein after single and multiple
 administration
This experiment adopts the method of multicenter, open, dose escalation study injection with
 recombinant human blood clean protein/granulocyte stimulating factor fusion protein after
 single and multiple doses of tolerance, security, and pharmacokinetic characteristics.

 Breast cancer patients with reduced white blood cells after chemotherapy were selected as
 subjects of this study.

 The three research doses that were to be incremented were 1.8 mg, 2.1mg and 2.4mg
 respectively, each of which was studied by single and multiple doses.

 Single dose of medicine, dose-climbing study.Two doses of the drug, dose-climbing study
