Details and patient eligibility

About

The purpose of this study is to determine the efficacy and safety of sorafenib in the neoadjuvant setting in patients with primary breast cancer

Full description

Epirubicin/Cyclophosphamide followed by Paclitaxel (EC/P) is a well tolerated regimen with high clinical activity. Histopathological complete remission after preoperative chemotherapy has a direct correlation with the disease-free and overall survival. The aim of combining a chemotherapy regime with sorafenib in the neoadjuvant setting is to increase the locoregional and systemic outcome of these patients

Inclusion criteria

Unilateral or bilateral primary carcinoma of the breast,
Tumor lesion in the breast with a palpable size of >= 2 cm. The lesion has to be measurable in two-dimensions preferably by sonography. In case of inflammatory disease the extent of inflammation can be used as measurable lesion;
Patients should have stages of disease in which adjuvant chemotherapy would be considered.
Women of childbearing potential must have a negative serum pregnancy test
Negative HER-2/neu status
Karnofsky Performance status index >= 80%;
Normal cardiac function
Laboratory requirements:

Absolute neutrophile count (ANC) >= 2,0 x 109/L and Platelets >= 100 x 109/L and Hemoglobin >= 10 g/dL (>= 6.2 mmol/L) INR ≤ 1.5 ULN and PTT ≤ 1.5 ULN within 14 days prior to enrolment ASAT or ALAT < 2.5 x ULN Alkaline phosphatase ≤ 5 UNL. Patients with ASAT and/or ALAT > 1,5 x UNL associated with alkaline phosphatase > 2,5 x UNL are not eligible for the study Total bilirubin < 1 X UNL Creatinine ≤ 175 µmol/L (2 mg/dl). The calculated creatinine clearance should be ≥ 60 mL/min.

Paraffin tumor tissue block and each one serum and one plasma sample centrally made available

Complete staging work-up within 3 months prior to registration.
Patients must be available and compliant for treatment and follow-up. Patients registered on this trial must be treated and followed up at the participating or a cooperating center.
