Brief summary

The aim of this project is to evaluate whether the sequence of Trastuzumab,pyrotinib and Nab-Paclitaxel in first line followed by SHR-A1811 in second line is superior to the sequence of SHR-A1811 in first line followed by Trastuzumab,pyrotinib and Nab-Paclitaxel in second line for HER2 positive breast cancer brain metastases.
