Primary	Immunogenicity Screening Incidence to Detect the Presence of Anti-PegG-CSF Antibodies.	Immunogenicity (anti-drug antibody; ADA) data is presented for all subjects' samples collected and a descriptive analysis is provided for immunogenicity (ADA) data.; Percentage incidence within + 10% of the expected ADA positivity incidence of Test (6% ADA in Test is anticipated from literature) is not considered clinically significant.; Evaluation of immunogenicity is carried out in a tiered fashion: Screening assay to assess if samples were positive or negative for anti-PegG-CSF.; Confirmatory assays for samples that were positive in the screening assay. The confirmatory assays assessed if antibodies were specific for INTP5, Neulasta, PEG and/or filgrastim.; Titer assay was performed to determine titer of the anti-PEG-GCSF antibody samples.; Neutralizing antibody (NAb) assay for those samples that were positive in the confirmatory assays to assess the neutralizing capability of the antibody to inhibit pegfilgrastim activity.	Samples (8 mL each) were withdrawn at screening, at pre-dose and at 336 (D-15, Week 2), 504 (D-22, Week 3, within 60 minutes before 2nd dose), 840 (D-36, Week 5), 1176 (D-50, Week 7), 1680 (D-71, Week 10) and 2016 (D-85, Week 12) hours after first dose.
