Summary of Clinical Use
Buparlisib is being assessed in clinical trials, including Phase II trials for metastatic transitional cell carcinoma of the urothelium (NCT01551030) and untreated squamous non-small cell lung cancer (NCT01820325). Click here to link to ClinicalTrials.gov's complete listing of buparlisib trials.
Mechanism Of Action and Pharmacodynamic Effects
Activation/dysregulation of PI3K signaling may contribute to tumorigenesis and tumor resistance to a many of the currently used antineoplastic agents. Buparlisib selectively inhibits class I PIK3 in the PI3K/AKT kinase (or protein kinase B) signaling pathway in an ATP-competitive manner, thereby inhibiting the production of the secondary messenger phosphatidylinositol-3,4,5-trisphosphate and activation of the PI3K signaling pathway. This may result in inhibition of tumor cell growth and survival in susceptible tumor cell populations.
