Precision Targeting of Mutant PI3Kα.

Abstract

PIK3CA, which encodes the p110α catalytic subunit of PI 3-kinase alpha (PI3Kα), is one of the most frequently genetically activated kinases in solid tumors. In two back-to-back papers, Varkaris and colleagues report on the development of a novel allosteric PI3Kα-mutant-selective inhibitor and early clinical experience with this compound.
