The purpose of this study is to increase survival of patients with early and locally advanced triple-negative breast cancer adding selumatinib to standard preoperative chemotherapy regimen.
Molecular analysis of residual tumor after administration of neoadjuvant chemotherapy revealed several mechanisms of resistance to treatment. High frequency of RAS-RAF-MEK-ERK signal pathway activation was found in cells of triple negative breast cancer after neoadjuvant chemotherapy, which correlated with high proliferation index and low pathological complete response rate. Thus, inhibition of MEK molecule - an intermediary transducer of this pathway may decrease activity of this pathway and restore tumor sensitivity to cytostatic agents. Hence, the use of SELUMETINIB, an oral selective inhibitor of MEK1/MEK2 kinases, in combination with Docetaxel should increase pathological complete response rate and in turn increase survival of patients with early and locally advanced triple-negative breast cancer.
