NCT05749016

Brief Summary

Inetetamab (Cipterbin) is a newly marketed anti-HER2 monoclonal antibody with amino acid modified Fc region and enhanced antibody-dependent cellular cytotoxicity (ADCC) effect. There was no robust evidence evaluating the combination of inetetamab with pertuzumab and neoadjuvant chemotherapy (paclitaxel + carboplatin) in the neoadjuvant setting. This study aimed to evaluate the efficacy and safety of inetetamab + pertuzumab+paclitaxel + carboplatin (TCbIP) as a neoadjuvant chemotherapy regimen in the treatment of patients with locally advanced HER2-positive breast cancer.

SINGLE GROUP
Model Details: The phase II trial included patients with histologically confirmed stage IIA to IIIC and HER2-positive primary invasive breast cancer from November 2021 to July 2023. Eligible patients received inetetamab with pertuzumab and paclitaxel/carboplatin (TCbIP) regimen every three weeks for a maximum of 6 cycles, followed by surgery. The primary endpoint was pathologic complete response (pCR; ypT0 ypN0) rate. Key secondary endpoints included near pCR (npCR) (residual breast disease \<1cm), objective response rate (ORR) and safety.
