Pharmacodynamic Study of BKM120 in Breast Cancer

Summary

BKM120 is a potent and highly specific oral pan-class I phosphatidylinositol-3-kinase (PI3K) inhibitor, currently under investigation in a first-in-man study in patients with advanced solid tumors (wild type and PIK3CA-mutated). Consistent, dose-dependent pharmacodynamic activity has been demonstrated and clear signs of anti-tumor activity have been seen with BKM120.
