| Measure | Time frame |
|---|---|
| Main Objective: To compare between SC trastuzumab and IV trastuzumab in the neoadjuvant setting • the serum trough concentrations (Ctrough) observed pre-surgery • the efficacy (pathological complete response, pCR) ;Secondary Objective: To compare between SC trastuzumab and IV trastuzumab • the observed Ctrough concentrations post-surgery • the predicted Ctrough concentrations pre-surgery and post-surgery • the pharmacokinetic profile To evaluate in the SC trastuzumab and IV trastuzumab arm • total pathological complete response (tpCR) • overall response rate (ORR) • time to response (TTR) • event-free survival (EFS) • overall survival • safety and tolerability • immunogenicity (evaluation of formation of anti-trastuzumab antibodies) ;Primary end point(s): The primary efficacy variable is pathological Complete Response (pCR). This is defined as the absence of invasive neoplastic cells of the primary tumor in the breast after surgery. The primary variable for the pharmacokinetic analysis will be the observed trough concentration Ctrough of trastuzumab at cycle 7 (ie. the measured pre-dose concentration value at cycle 8). | — |
