NCT07271992

Brief Summary

Refining neoadjuvant chemoimmunotherapy and establishing predictive biomarkers remain pivotal challenges in early TNBC. Although SG/I (sacituzumab govitecan/PD-1 inhibitor) shows clinical promise, validation of responder identification tools is warranted. This phase II trial aims to identify a precision TNBC population suitable for de-escalated neoadjuvant therapy with sacituzumab govitecan plus tislelizumab, based on differential Trop-2 expression (±) and PD-L1 status (CPS \>10% vs. \<10%). Primary endpoints include pCR rate and safety; exploratory biomarker analyses will assess mechanisms of response/resistance
