Design outcomes

Primary

MeasureTime frame
Main Objective: To investigate the activity of EndoTAGTM-1 + paclitaxel combination therapy in patients with Her2-negative BC candidate for neoadjuvant chemotherapy, as measured by the decrease in MRI-estimated tumour volume at the end of EndoTAGTM-1 + paclitaxel administration vs. baseline. ;Secondary Objective: To evaluate: •Reduction in tumor size as defined by MRI-measured greatest diameter(s) following RECIST criteria at the end of EndoTAGTM-1 + paclitaxel administration •Decrease in MRI-estimated tumor perfusion at the end of EndoTAGTM-1 + paclitaxel administration •Pathological complete response (pCR) •Rate of residual cancer burden at time of surgery •Safety and tolerability of the neoadjuvant regimen •Rate of breast-conserving surgery (BCS) •Rate of clinical complete and partial responses (CR, PR) •Rate of lymph node-negative disease after treatment (node-NEG) To collect frozen tumor biopsies at baseline and surgery for future translational research on DNA and RNA ;Primary end point(s): The percent reduction in MRI-estimated tumor volume at the end of EndoTAGTM-1 + paclitaxel administration vs. baseline.;Timepoint(s) of evaluation of this end point: The end of EndoTAGTM-1 + paclitaxel administration

Secondary

MeasureTime frame
Secondary end point(s): • The percent reduction in linear tumour size as measured on MRI by the greatest linear diameter(s) of the tumour following RECIST criteria at the end of EndoTAGTM-1 + paclitaxel administration • The percent reduction in MRI-estimated tumour perfusion at the end of EndoTAGTM-1 + paclitaxel administration • Pathological complete response (pCR) is defined as the absence of any residual invasive cancer in the breast and the absence of any metastatic cells in the regional lymph nodes at the time of surgery (University of Texas MD Anderson Cancer Center trial’s pCR criteria) • Residual cancer burden (RCB) scores are calculated according to the RCB index proposed by Symmans et al (2007) • Rate of breast-conserving surgery (BCS) • Rate of clinical complete and partial responses (CR, PR) • Rate of lymph node-negative disease after treatment (node-NEG) ;Timepoint(s) of evaluation of this end point: The end of EndoTAGTM-1 + paclitaxel administration Surgery
