Crenigacestat, also known as LY3039478, is a orally bioavailable, novel small molecule Notch inhibitor with an IC50 of ~1nM in most of the tumor cell lines tested. LY3039478 potently inhibits mutant Notch receptor activity. In a xenograft tumor model, LY3039478 inhibited N1ICD cleavage and expression of Notch-regulated genes in the tumor microenvironment. LY3039478 is being investigated in Phase I.
