Summary

This early-phase trial tested a combination of two oral drugs, BKM120 and lapatinib, in 24 people with HER2-positive breast cancer that had stopped responding to trastuzumab. The goal was to find a safe dose and see if the combination could shrink tumors. The study was terminated early, so full results are not available.
