Mechanism of action

Gamma-secretase is an intramembrane protease complex that cleaves Notch receptors and other substrates. In desmoid tumors, aberrant Notch signaling promotes fibroblast proliferation and tumor growth. By blocking gamma-secretase activity, nirogacestat suppresses Notch-driven proliferation and induces tumor regression or stabilization. This mechanism is particularly relevant in desmoid tumors with CTNNB1 mutations that activate Wnt/β-catenin signaling, which cooperates with Notch signaling.
