Description

AMG 900 is a potent and highly selective pan-aurora kinase inhibitor with IC50 values of 5, 4 and 1 nM for Aurora A, B and C respectively. AMG 900 inhibited autophosphorylation of aurora-A and -B as well as phosphorylation of histone H3 on Ser(10) in tumor cells. AMG 900 exhibited acceptable PK properties in preclinical species and was predicted to have low clearance in humans. Oral administration of AMG 900 blocked the phosphorylation of histone H3 in a dose-dependent manner and significantly inhibited the growth of HCT116 tumor xenografts. Importantly, AMG 900 was broadly active in multiple xenograft models, including 3 multidrug-resistant xenograft models, representing 5 tumor types. AMG 900 is currently in Phase I clinical testing as a treatment for solid tumours.
