PRIMARY outcome

Timeframe: 2 weeks

Population: 10 subjects took study drug and completed surgery

Pre- and post-treatment samples will be assessed by immunohistochemistry for positivity for Ki-67.

OTHER_PRE_SPECIFIED outcome

Timeframe: 2 weeks

Population: 6 patients that got the study drug and completed surgery by RET expression were analyzed

Results will be stratified by RET gene expression, a negative prognostic indicator in breast cancer, to demonstrate that RET is a marker of response.
