Brief Summary:
This study was designed to evaluate the efficacy and safety of pyrotinib combined with albumin paclitaxel and trastuzumab in the treatment of Her2-positive early or locally advanced breast cancer, and to explore RCB scores and TILs expression and other related molecular markers for pyrrole the efficacy of the treatment with pyrotinib.

Condition or disease Intervention/treatment Phase
Breast Cancer HER2 Positive Combination Chemotherapy Drug: Pyrotinib Maleate Tablets Drug: Albumin Paclitaxel Drug: Trastuzumab Phase 1 Phase 2

Detailed Description:

At present, the treatment mode of breast cancer has gradually turned to the individualized comprehensive treatment mode combining systemic therapy and local therapy, and neoadjuvant therapy is widely used. Albumin-bound paclitaxel alters the excipients, reduces adverse reactions and greatly enhances efficacy, facilitating clinical applications. Studies have shown that in the use of neoadjuvant chemotherapy, drugs containing purple shirts and anthracyclines will be the drug of choice. The HER2/erbB2 molecule is an independent prognostic factor for breast cancer. About 20%-30% of adenocarcinoma patients have amplification/overexpression of HER2 gene. These patients are insensitive to conventional therapy and are more prone to recurrence and metastasis. Shorter survival and poorer prognosis. Current drugs targeting HER2 targets mainly include macromolecular monoclonal antibodies and their conjugates and small molecule tyrosine kinase inhibitors. Pyrotinib is an irreversible inhibitor of small targets (EGFR and HER2). Compared with trastuzumab, it has different sites of action, which may lead to synergy in the treatment of human Her2-positive breast cancer.

The excellent clinical efficacy of dual-targeted neoadjuvant therapy for Her2 positive breast cancer, the anti-tumor effect and good tolerance of pyrotinib, we intend to develop a pyrotinib combined with albumin paclitaxel and trastuzumab one-arm exploratory clinical study of neoadjuvant therapy for Her2-positive early or locally advanced breast cancer with the aim of assessing efficacy and safety, and exploring the efficacy of tumor-associated molecular markers such as RCB scores and TILs expression for pyrotinib treatment predicting effectiveness.

Arm Intervention/treatment
Experimental: Pyrotinib Combined With Albumin Paclitaxel and Trastuzumab


-Drug: Pyrotinib Maleate Tablets combined with Albumin Paclitaxel and Trastuzumab.

Surgery:Subjects should be evaluated by tumor-enhanced MRI combined with mammary gland ultrasound during the preoperative neoadjuvant administration, and evaluated every 2 cycles. The subjects who were evaluated for CR and PR for the first time should be confirmed after at least 4 weeks. The confirmed tumor assessment cannot change the previously fixed examination time point.


  • Drug: Epirubicin hydrochloride combined with Cyclophosphamide
  • At the same time, according to the recommendation of the clinician, choose whether to accept the same anti-HER2 treatment plan before surgery. For patients with tumors positive for estrogen receptor (ER) and/or progesterone receptor (PR), endocrine therapy should be given at the end of adjuvant chemotherapy, and if there is clinical indication at the end of adjuvant chemotherapy, radiotherapy should be given.

Primary Outcome Measures :
  1. pathologic Complete Response(pCR)(ypT0/is N0) [ Time Frame: Postoperative evaluation after completion of neoadjuvant therapy (approximately 24 weeks) . ]
    Invasive tumor residuals in the breast and axillary lymph nodes without microscopic examination, ductal carcinoma in situ may exist.

Secondary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: up to 2 years ]
    The proportion of patients with a best overall confirmed response of CR or PR in the whole body as assessed per RECIST 1.1 by the investigator.

  2. Disease Control Rate (DCR) [ Time Frame: up to 2 years ]
    The proportion of patients with a best overall response of CR, PR or SD in the whole body, as assessed per RECIST1.1 by the investigator.

  3. Residual Cancer Burden (RCB) [ Time Frame: up to 2 years ]
    The RCB category (RCB-0, RCB-I, RCB-II, or RCB-III) was defined according to the M.D. Anderson Cancer Center standard, and the RCB score was associated with the patient's prognosis.

  4. Tumor Infiltrating Lymphocytes (TILS) [ Time Frame: up to 2 years ]
    This outcome measure is designed to measure the amount of TILs in newly diagnosed luminal A and Triple Negative Breast Cancer (TNBC) tumors. The mean percent change in TILS in tumor tissue from initial core biopsy samples will be compared with pathology samples from definitive surgery after IORT between the two different breast cancer sub types.
