Summary

This early-phase study tests a new oral drug, ATV-1601, in people with advanced solid tumors or certain breast cancers that have a specific AKT1 E17K mutation. The main goals are to check safety, find the right dose, and see how the drug moves through the body. About 134 adults will take part, and some may also receive a second drug called fulvestrant.
