Abstract 2590: KD019: Blood brain barrier penetrant HER2/neu, Src, and EGFR inhibitor

KD019 is an orally bioavailable small molecule inhibitor of molecular drivers of cancer growth and progression, including HER2/neu, Src family nonreceptor tyrosine kinases (Src) and EGFR. This profile of activity underlies the robust activity of KD019 in animal models of cancer. Although alternative agents targeting these tyrosine kinase receptors are available, only KD019 targets all of these pathways without the need for a combination strategy. A more important shortcoming of alternative agents is a lack of blood brain barrier (BBB) penetration (Brain/Plasma concentration ratio
