Clinical Trial Summary

This is a Phase III, randomised, assessor-blind, parallel group, multicentre trial. At least 180 adult subjects with high-risk Stage II or Stage III / IV breast cancer will be randomised (1:1) to receive either Eurofarma's pegfilgrastim (n = 90) or Neulastim (n = 90) in 8 to 10 sites in Brazil. Subjects will undergo a maximum of 4 cycles of myelosuppressive chemotherapy (21 days per cycle).

12. Female subjects of childbearing potential must have a negative serum pregnancy test within 14 days of first dose of trial treatment and agree to use highly effective contraception (e.g. hormonal contraception or intra-uterine device [which should be established prior to the start of the trial], plus usage by at least 1 of the partners of an additional spermicide-containing barrier method of contraception) from 2 weeks prior to administration of the first dose of trial medication until trial completion, and for 30 days after the last dose of trial drug

8. Severe valvular heart disease, myocardial infarction, heart failure, unstable angina pectoris, uncontrolled hypertension, or uncontrolled arrhythmias within 6 months of the Screening Visit

9. Significant neurologic or psychiatric disorders including psychotic disorders, dementia, or seizures that would prohibit the understanding and giving of informed consent
