Brief Summary

This study is a single-arm, open-label, phase II study, comparing the efficacy and safety of pyrotinib plus trastuzumab and aromatase inhibitors, in the treatment of HR (hormone receptor)+/HER2 (human epidermal growth factor receptor 2) + MBC and inoperable LABC patients.

Detailed Description

This is a exploratory, single-arm, open-label,multicenter phase II trial. Our primary purpose is to compare that PFS of patients with pyrotinib plus trastuzumab and AI for HER2-positive and hormone receptor-positive MBC or locally advanced breast cancer (LABC).

In treatment period, patients will be administrated pyrotinib plus trastuzumab and aromatase inhibitors, every 21 days for 1 cycle, until disease progression, toxicity intolerance, withdrawal of informed consent, patients judged must be terminated study termination.

The imaging evaluation was performed according to the RECIST 1.1 criteria every 6 weeks.

Conditions

Study Groups

Pyrotinib and trastuzumab plus aromatase inhibito

Participants will receive pyrotinib in combination with trastuzumab plus AI until pre-defined study end, disease progression, unacceptable toxicity, withdrawal of consent or death, whichever occurs first.
