Eligible subjects are randomly assigned to receive once-per-cycle DA-3031(PEG-G-CSF) or daily G-CSF(up to 10 days). This study is conducted for 6 cycles of chemotherapy, that each cycle is repeated every 21 days.
This study is to determine whether once-per-cycle DA-3031(PEG-G-CSF) is not inferior to daily G-CSF in chemotherapy-induced neutropenia.
