Neutropenia, Breast Cancer, GW003
Brief summary
The purpose of the present trial is to evaluate the safety, tolerability and pharmacokinetics(PK)/pharmacodynamics(PD) of single subcutaneous injection of GW003 in breast cancer patients. Moreover, the efficacy will be assessed preliminary.
Detailed description
This is an single-center, open-label, randomized, active-controlled phase I study evaluating tolerability and pharmacokinetics/pharmacodynamics of single subcutaneous injections of GW003 in the breast cancer patients.GW003 is recombinant human serum albumin/human granulocyte-colony stimulating factor(I)fusion protein .It is a long-acting G-CSF(Granulocyte-Colony Stimulating Factor). In this study, participants will be administered a single dose of GW003. Every subject will only accept one dose. In addition to tolerability and safety, pharmacokinetics/pharmacodynamics, preliminary efficacy and immunogenicity of GW003 will be evaluated as well.
