Human endometrial FGFR2-N549K-mutated AN3CA cancer cells were treated with futibatinib plus either everolimus or MK2206 or with each agent alone…In ANC3A cells, the combination of futibatinib with MK2206 inhibited AKT phosphorylation; futibatinib plus either MK2206 or everolimus inhibited mTOR phosphorylation to a greater degree than monotherapy...The combination of futibatinib plus a PI3K pathway inhibitor resulted in synergistic antitumor effects.
