- Primary Outcome Measures
Name Time Method Main Objective: Primary objective is to assess the pathological Complete Response (pCR) rate in the breast of patients treated in following combinaisons: SAR240550 twice-weekly + weekly paclitaxel, SAR240550 weekly+ weekly paclitaxel, and weekly paclitaxel single agent as calibrator.;Secondary Objective: - pCR rate in the breast and axilla,<br>-Radiological/clinical objective response rate (ORR), breast conservation rate, disease free survival (DFS), and overall survival (OS), in each treatment arm, <br>- Safety profiles of study combinations and of the single agent reference treatment,<br>- Molecular characteristics of the tumor tissue and any correlation between the biological activity of the study treatment and the disease outcome.<br>;Primary end point(s): pCR rate defined as the complete absence of invasive carcinoma on histological examination of the breast at the time of definitive surgery and confirmed by independent blinded centralized review.
