Summary

This study tests a new drug called HRS-8080 against standard treatments chosen by doctors for women with advanced breast cancer that has worsened after hormone therapy. About 240 women aged 18-75 will take part. The main goal is to see if HRS-8080 can delay cancer growth longer than current options.
