GSE149322 AKT/mTOR/HER/PI3K family genes as predictors of pCR for early stage breast cancer patients treated with the AKT inhibitor MK2206 in the I-SPY 2 TRIAL (NCT01042379)

Based on the hypotheses that since MK2206 is an enzymatic inhibitor of AKT, response to MK2206 may be predicted by the relative pre-treatment levels of AKT kinase substrates, in pre-defined analyses we assessed 10 genes in the HER-AKT-mTOR pathway to test their association with pCR (complete pathologic response) in the MK2206 arm, in both HER2+ and HER2- subsets. We also tested 9 genes genes previously associated with response to MK2206 in vitro and in the HER2+ metastatic setting, and performed exploratory association analyses using whole-transcriptome data to identify additional predictive signals outside the HER-AKT-mTOR pathway.
