BAY1082439 is an orally bioavailable inhibitor of the class I phosphoinositide 3-kinase (PI3K) alpha and beta isoforms with potential antineoplastic activity. BAY 1082439 showed clear advantages over the strong PI3Kα inhibitor BAY 80-6946 in PTEN/PI3Kα-driven tumor models (e.g., PC3 and HEC-1B), when the two compounds were compared at their MTDs. Furthermore, BAY 1082439 has unique pharmacokinetic (PK) properties with very high plasma free fractions across all species tested (33-50%), large Vss, high clearance and intermediate T1/2.
With once daily dosing, BAY 1082439 could induce tumor regression in KPL4 (PIK3CAmut and HER2+), and tumor stasis in HEC-1B (PTENdel) and in HEC-1A (PIK3CAmut) tumor models.
