Primary Outcome Measures
NameTimeMethod
Main Objective: - To determine the rate of pCR in the breast and axilla (ypT0/is, ypN0). Pathological complete response is defined as no presence of invasive residuals in the breast and resected axillary lymph nodes. ;Secondary Objective: - To evaluate the toxicity of the study regimen<br>- To evaluate the drug delivery<br>- To evaluate clinical response rate (RECIST 1.1) by mammography and sonography in breast and axilla.<br>- To evaluate breast-conserving surgery rate<br>- To evaluate progression free survival <br>- To evaluate overall survival<br>- To evaluate the percentage of patients with BRCA1, BRCA2, or CHEK2 mutation in this population.<br>- To evaluate tumor infiltrating lymphocytes on the residual tumor<br>- To do genome analysis on tissue samples;Primary end point(s): - The rate of pCR in the breast and axilla (ypT0/is, ypN0);Timepoint(s) of evaluation of this end point: After surgery when part 1 and 2 of treatment are ended
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): - Safety<br>- The drug delivery<br>- Clinical response rate<br>- Rate of breast conserving surgery<br>- PFS<br>- OS<br>- Percentage of patients with BRCA1, BRCA2, or CHEK2 mutation in this population<br>- Percentage of tumor infiltrating lymphocytes on residual tumor<br>- Subsequent genomic studies on the tumor and germline DNA's;Timepoint(s) of evaluation of this end point: during and after part 1 and 2 of treatment
