Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is to evaluate the progression-free survival (PFS) of SHR-A1811 combined with SHR-1316 in the first-line treatment of PD-L1-positive locally recurrent unresectable or metastatic triple-negative breast cancer with Toripalimab combined with Nab-paclitaxel, as assessed by blinded independent central review (BICR).
