This enzyme is part of the phosphoinositide-3-kinase/α-serine/threonine-protein kinase/mammalian target of rapamycin signaling pathway, which promotes cell growth and survival. Mutations in the phosphoinositide-3-kinase gene cause the phosphoinositide-3-kinase signaling pathway to become overactive, leading to uncontrolled cell growth and survival, which contributes to tumor development. By inhibiting phosphoinositide-3-kinase-alpha, alpelisib can slow tumor growth and kill cancer cells. The goal of this study was to develop and validate a new, sensitive, specific, and rapid liquid chromatography-tandem mass spectrometry method for measuring alpelisib in dried blood spots from both mice and humans. Filgotinib served as the internal standard, and all procedures adhered to regulatory standards.
