Neoadjuvant Treatment Pegylated Liposomal Doxorubicin Plus Cyclophosphamide Sequential Docetaxel Plus Trastuzumab and Pertuzumab Versus Docetaxel Plus Carboplatin Combined With Trastuzumab and Pertuzumab in HER-2 Positive Breast Cancer

A Multicentre, Open-label, Randomised Trial of Neoadjuvant Pegylated Liposomal Doxorubicin Plus Cyclophosphamide Sequential Docetaxel Plus Trastuzumab and Pertuzumab Versus Docetaxel Plus Carboplatin Combined With Trastuzumab and Pertuzumab in HER-2 Positive Breast Cancer

This is a multicenter, open label, non-inferiority, randomized controlled clinical study.

The aim of this study is to evaluate the efficacy and safety of a pegylated liposomal doxorubicin + cyclophosphamide followed by docetaxel plus trastuzumab and pertuzumab (PLD + C + HP followed by THP) regimen compared with a docetaxel + carboplatin plus trastuzumab and pertuzumab (TCbHP) regimen in the neoadjuvant treatment of HER-2-positive breast cancer.
