Popis: | Outcomes of adults with AML remain unsatisfactory. To explore the role of the AKT signaling pathway in AML, we examined samples from AML patients (pts) utilizing reverse phase protein arrays (RPPAs). High levels of the phosphorylated Ser473 form of AKT were associated with shorter remission (p=0.03) and shorter overall survival (p=0.09) in 92 newly diagnosed AML pats with intermediate-risk cytogenetics undergoing induction chemotherapy, identifying AKT as rational drug target. We studied the effects of MK-2206, an investigative oral, highly specific allosteric inhibitor of the 3 isoforms of human AKT, in human AML. MK-2206 dephosphorylated AKT and inhibited growth of AML cell lines and primary AML blasts at low-micromolar concentrations. We then conducted a phase 2 trial of MK-2206 (200 mg once weekly) in adult pats who had failed 1 other therapy for persistent AML or relapsed after a prior CR Citation Format: Marina Y.
