Spots Global Cancer Trial Database for Pyrotinib as Neoadjuvant Agent for Non-objective Response HER2-positive Early Breast Cancer

Study Description

Brief Summary: The study assesses the efficacy of neoadjuvant treatment with pyrotinib and trastuzumab with chemotherapy, mainly pathological complete response (pCR) rates in the breast and axilla. And also assesses side effects, event-free survival (EFS), disease-free survival (DFS), distant disease-free survival (DDFS), and objective response rates (ORR).

Detailed Description: Investigational Medical Products (IMPs) will be pyrotinib (B), trastuzumab (H), pertuzumab (P), docetaxel (T), epirubicin (E), and cyclophosphamide (C). Magnetic resonance imaging (MRI) will be performed at baseline and 2 cycles after neoadjuvant therapy with trastuzumab, pertuzumab, and docetaxel (THP\*2). Non-objective response patients will be randomly assigned (2:1) to receive 2 cycles of pyrotinib and trastuzumab with docetaxel followed by 4 cycles of pyrotinib and epirubicin plus cyclophosphamide (THB\*2-ECB\[epirubicine, cyclophosphamide, and pyrotinib\]\*4, cohort A), or 2 cycles of trastuzumab and pertuzumab with docetaxel followed by 4 cycles of epirubicin plus cyclophosphamide (THP\*2-EC\*4, cohort B). During the neoadjuvant therapy, the side effects and all the events were recorded and analyzed. After surgery, the efficacy of pCR rate and ORR were analyzed. And long time follow-up will also be performed to analyze EFS, DFS, DDFS, and ORR.
