Brief summary: This study will evaluate the pharmacokinetics (relative bioavailability) and pharmacodynamics, after single subcutaneous application, in healthy volunteers of both sexes, between pegfilgrastim formulation, produced by Eurofarma Laboratorios S/A and Neulastim® (reference formulation), marketed by Produtos Roche Químicos e Farmacêuticos S/A.

In addition to that, a pharmacodynamics comparison will be performed, through change in absolute neutrophil count in leukogram performed in the same time of pharmacokinetics analysis collection and through CD34+ cell count in peripheral blood at timepoints 0:00, 96:00 and 384:00 hours.

* Treatment in the last 3 months before starting this study treatment with any drug product known to have a well-defined toxic potential in large organs.
* Participation in any pharmacokinetics study with collection of more than 300 mL of blood or intake of any experimental drug product in the last six months before starting the study treatment.
* Donation or loss of 450 mL or more of blood in the last three months preceding the study or donation of more than 1500 mL of blood in the last 12 months before starting the study treatment.
* Reagent result for urine βHCG exam, performed in female volunteers.
* Positive result in urine test for detection of abuse drugs.
* Result higher than 0.1 mg/L in ethylometer test.
* Any condition preventing participation in the study as per researcher's opinion.
