What this Trial Is About

Neratinib is an irreversible pan-HER tyrosine kinase inhibitor (TKI). Currently, no studies have investigated the use of macromolecular anti-HER2 agents combined with TKIs for the treatment of non-pCR HER2-positive breast cancer following neoadjuvant therapy. Furthermore, there are no prospective randomized controlled trials comparing trastuzumab plus pertuzumab versus trastuzumab plus TKIs in HER2-positive breast cancer patients with residual cancer burden class (RCB) I or II after neoadjuvant trastuzumab and pertuzumab. Therefore, this study aimed to evaluate the efficacy and safety of adjuvant trastuzumab plus neratinib in patients with hormone receptor-positive/HER2-positive breast cancer and RCB 0/I following neoadjuvant trastuzumab and pertuzumab therapy.
