Pyrotinib as Neoadjuvant Agent for Non-objective Response HER2-positive Early Breast Cancer

Pyrotinib as Neoadjuvant Agent for Non-objective Response Patients of HER2-positive Early Breast Cancer Treated by Trastuzumab, Pertuzumab, and Chemotherapy (PYHOPE-BC-104): a Randomized, Controlled, Phase Ⅱ Trial

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).

Study Overview

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.

11. Signed informed consent form (ICF).

Exclusion Criteria:

  1. Metastatic breast cancer;
  2. Previous (less than 10 years) or current history of malignant neoplasms, except for curatively treated: Basal and squamous cell carcinoma of the skin; Carcinoma in situ of the cervix.
  3. Patients with a prior malignancy diagnosed more than 10 years prior to randomization may enter the study. Patients must have been curatively treated with surgery alone. Radiation therapy or systemic therapy (chemotherapy or endocrine) are NOT permitted. Prior diagnoses of breast cancer or melanoma are excluded.
  4. Concurrent treatment with an investigational agent or participation in another therapeutic clinical trial;
  5. Major surgical procedure or significant traumatic injury within 14 days prior to randomization or anticipation of the need for major surgery within the course of the study treatment.
  6. Known history of uncontrolled or symptomatic angina, clinically significant arrhythmias, congestive heart failure, transmural myocardial infarction, uncontrolled hypertension (≥180/110), unstable diabetes mellitus, dyspnoea at rest, or chronic therapy with oxygen;
  7. Known hypersensitivity reaction to one of the investigational compounds or incorporated substances.
  8. Pregnant or lactating patients. Patients of childbearing potential must implement adequate non-hormonal contraceptive measures during study treatment.
  9. Concurrent disease or condition that would make the subject inappropriate for study participation or any serious medical disorder that would interfere with the subject's safety.

To describe the safety of the various regimens toxicity is compared between the two arms.
up to 30 weeks
Objective response rate (ORR)
Time Frame: up to 30 weeks
ORR is defined as the proportion of patients who achieved a complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
up to 30 weeks
Disease-free Survival (DFS)
Time Frame: Following surgery, every 12 months until Year 10
DFS was defined as the time from surgery to the first date of breast cancer relapse, second primary tumor (including contralateral breast cancer), or death without documented prior relapse. Data will be reported when they are mature and available, likely when a median of 3 years follow up has been reached.
Following surgery, every 12 months until Year 10
Event Free Survival (EFS)
Time Frame: From date of randomization until follow-up to 10 years
EFS will be defined as the time from random assignment to documentation of the first of the following events: discontinuation of study therapy due to protocol-defined progression prior to surgery; local, regional, or distant recurrence of breast cancer following curative surgery; a new breast cancer; another new onset malignancy; or death as a result of any cause.
