Effectiveness and Safety Study of Filgrastine® in Patientes With Breast Cancer Treated With Myelotoxic Chemotherapy

Summary

Randomized Study of the Clinical Efficacy and Safety of Filgrastine® in Patients with Breast Cancer Treated with Myelotoxic Chemotherapy. Primary Objective: to evaluate the activity and safety of Filgrastine® in Brazilian patients undergoing adjuvant treatment for breast cancer, with the frequency of grade 4 neutropenia in the first cycle of chemotherapy as the primary endpoint. Secondary Objectives: * Frequency of febrile neutropenia during treatment; * Frequency of neutropenia of any degree in the first cycle; * Frequency of hospitalization during treatment; * Duration of grade 4 neutropenia in the first treatment cycle; * Toxicity during treatment; * Immunogenicity throughout treatment. All endpoints will be descriptively analyzed in both groups of patients. Study design Randomized (2:1), open-label, multicenter study. Chemotherapy will be given on the first day of each cycle of treatment, for a maximum of four to eight cycles, depending on the regimen, patients whose chemotherapy treatment is prolonged beyond this period being withdrawn from the study.
