- Evaluate changes in the expression of targeted biomarkers in invasive breast cancer tissue before and after SNDX-275 administration [ Time Frame: 14 days ]
- Evaluate changes in gene and/or protein expression of exploratory biomarkers in invasive breast cancer tissue before and after SNDX-275 administration, as tissue sample permits. [ Time Frame: 14 days ]
- Evaluate safety and tolerability of SNDX-275 as measured by adverse events and changes in laboratory safety parameters [ Time Frame: 14 days ]
