Trial to Compare the Efficacy and Safety of Pegfilgrastim Biosimilar in Subjects With High Risk Stage Breast Cancer Receiving Chemotherapy

A Randomized, Assessor-blind, Parallel Group, Multicentre Phase III Trial to Compare the Efficacy and Safety of Eurofarma's Pegfilgrastim to Neulastim® in Subjects With High Risk Stage II or Stage III / IV Breast Cancer Receiving Chemotherapy.

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).

7. Clinically significant impairment of LVEF
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
