Mechanism of Action

Targets/IC₅₀/Ki	PI3Kα (Cell-free assay) 5 nM
In vitro	Alpelisib (BYL719) inhibits the proliferation of breast cancer cell lines harboring PIK3CA mutations, correlating with inhibition of various downstream signaling components of the PI3K/Akt pathway.
In vivo	Alpelisib (BYL719) shows statistically significant dose-dependent anti-tumor efficacy in PIK3CA mutant xenograft models in rodents at doses exceeding 270 mg/d. It has a low clearance, a half-life of 8.5 h, and its exposure increases dose proportionally between 30mg/d and 450mg/d, displaying low inter-individual variability in Cmax and AUC in humans. At 270 mg/d, this compound shows first signs of clinical efficacy, including 1 confirmed partial response in a patient with ER+ breast cancer, and significant PET responses (PMR) and/or tumor shrinkage are achieved in 8 out of 17 evaluated patients.
