GNE-477 is a potent and efficacious dual PI3K (IC₅₀=4 nM)/mTOR(K_i=21 nM) inhibitor.

GNE-477 (Compound 8) has improved potency in the MCF7.1 cell proliferation assay with an EC₅₀ of 143 nM^[1].

GNE-477 also exhibits stasis in a PC3 tumor growth inhibition study. In an experiment evaluating the tumor growth inhibition of a PC3 tumor xenograft over 14 days, stasis is achieved at a 20 mg/kg QD dose and significant inhibition is observed with doses as low as 1 mg/kg QD. GNE-477 is generally well tolerated during this study as demonstrated by acceptable levels of weight loss comparable to that observed with the animals in the vehicle cohort^[1].

Mice, Rats and Dogs^[1]
Female nu/nu mice are dosed with the GNE-477 HCl salt as a solution intraveinously (1 mg/kg) in 5% DMSO/5% cremophor and dosed orally as a solution in 80% PEG (5 mg/kg). Male rats are dosed with the GNE-477 TFA salt as a solution intraveinously (1 mg/kg) in 5% DMSO/5% cremophor and dosed orally as a solution in 80% PEG (5 mg/kg). Male beagle dogs are dosed with the GNE-477 HCl salt as a solution intraveinously (1 mg/kg) in 10% HP-β-CD and dosed orally as a suspension in MCT (2 mg/kg). Efficacy study of GNE-477 in the PC3-NCI tumor xenograft model is proformed. The percent of tumor growth inhibition (TGI) at the end of study (day 14) is measured and compared with the vehicle control group.
