Summary

This study tests a combination of three drugs (atezolizumab, trastuzumab, and vinorelbine) in people with advanced HER2-positive breast cancer that has stopped responding to standard treatments. The goal is to see if this mix can shrink tumors. About 55 participants will receive the treatment, and researchers will track how many respond. This is not a cure, but aims to control the disease.
