SECONDARY outcome

Timeframe: Up to 4 weeks

Safety and tolerability of dasatinib in participants with operable Triple negative breast cancer (TNBC) will be based on NCI Adverse Events (AE) Version 4.0 and will be assessed by frequency tables. AEs were collected on day 1 of treatment and a minimum of 14 days after the last dose. AEs reported here were ranked as either possibly related, probably related, or definitely related to the study intervention. All AEs (including not related and unlikely related) are summarized in the AE section.

Examine pCR rates to standard neoadjuvant chemotherapy in nuclear Epidermal Growth Factor Receptor (nEGFR) + TNBC. pCR will be defined as ypT0 ypNO (absence of cancer in breast tissue and lymph nodes) an assessed by the investigator.
