E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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)
|
|
E.2.2 | Secondary objectives of the trial |
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)
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
-Conversion of HER2 status: HER2 status will be compared between the tumor sample obtained at initial diagnosis and the tumor sample taken from primary tumor remnants at surgery.
-Fcy-receptor polymorphism: to further explore the relationship of Fcγ-receptor polymorphisms and response to trastuzumab 3 ml of whole blood samples will be taken at baseline.
-Exploratory Biomarker analysis: to identify dynamic biomarkers that may be predictive of response to trastuzumab treatment (in terms of efficacy, dose, safety and tolerability) and will help to better understand the pathogenesis, course and outcome of breast cancer and related diseases. |

E.5 End points |
E.5.1 | 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). |
