SPI-2012 vs Pegfilgrastim in Management of Neutropenia in Breast Cancer Participants With Docetaxel and Cyclophosphamide

This is a Phase 3, randomized, open-label, active-controlled, multicenter study to compare the efficacy and safety of SPI-2012 versus pegfilgrastim in participants with early-stage breast cancer treated with TC chemotherapy as measured by the duration of severe neutropenia (DSN). Each cycle was 21 days. Four cycles were evaluated for this study. On Day 1 of each cycle, participants received TC chemotherapy. On Day 2 of each cycle, participants received study drug (SPI-2012 or pegfilgrastim). After cycle 1, as applicable, participants who received at least one dose of study drug will be followed for safety for 12 months after the last dose of study treatment.
