Summary

First preclinical data suggest that pegfilgrastim could constitute a potent adjuvant for immunotherapy with mAb possessing ADCC/ADCP properties as trastuzumab. Combined treatment of pegfilgrastim and trastuzumab should translate into an increased rate of pathological clinical response. Therefore the investigators' proposal is to evaluate the clinical and biological impact of pegfilgrastim in combination with trastuzumab + paclitaxel in HER2-positive early stage breast cancer patients. Breastimmune02 is a multicenter, randomized, open-label, Phase II trial. Operable HER2+ breast cancer patients previously treated with 4 cycles of standard adriamycine/cyclophosphamide (AC) chemotherapy will be randomized (1:1) to receive in the neoadjuvant setting:Arm A: weekly paclitaxel + trastuzumab (every 3 weeks, Q3W) + pegfilgrastim (Q3W) versus Arm B: weekly paclitaxel + trastuzumab (Q3W).Stratification criteria will be: cN0 versus cN1.
