To examine the efficacy and feasibility of combination therapy with alectinib and ixazomib in ALK/TP53 comutated NSCLC cells in vivo, we treated immunodeficient mice bearing A925L tumor xenografts with alectinib or ixazomib monotherapy, or the combination therapy of both....combined alectinib and ixazomib therapy caused remarkable tumor shrinkage, and three of the eight tumors completely regressed (Fig. 5A; Supplementary Fig. S8A).
