Overview

A triple combination therapy consisting of buparlisib (a pan-class I phosphoinositide 3-kinase inhibitor), fulvestrant (a selective estrogen receptor degrader), and ribociclib (a CDK4/6 inhibitor). This combination was investigated for the treatment of hormone receptor-positive (HR+), HER2-negative advanced breast cancer. The combination targets multiple pathways involved in cancer progression but was not advanced to phase II studies due to unexpected toxicity.
