Summary

This is a single-arm, multicenter clinical study designed to evaluate the efficacy and safety of pyrotinib and trastuzumab combined with pegylated liposomal doxorubicin hydrochloride and cyclophosphamide followed by paclitaxel for injection albumin bound as neoadjuvant therapy in patients with early HER2-positive breast cancer.

Eligible patients will receive 8 cycles of neoadjuvant treatment. Pyrotinib will be administered orally once daily, and trastuzumab will be administered intravenously every 3 weeks. During the first 4 cycles, patients will receive pegylated liposomal doxorubicin hydrochloride and cyclophosphamide. During the subsequent 4 cycles, patients will receive paclitaxel for injection albumin bound. The primary outcome is total pathological complete response rate. Secondary outcomes include breast pathological complete response rate, lymph node pathological complete response rate, objective response rate, event-free survival, distant disease-free survival, overall survival, and safety.

Conditions

Interventions

DRUG

Pyrotinib Maleate

Pyrotinib maleate will be administered orally at 400 mg once daily from Day 1 of Cycle 1. It should be taken within 30 minutes after breakfast and continued throughout the neoadjuvant treatment period.

DRUG

Trastuzumab (H, 8mg/kg

Trastuzumab will be administered intravenously at a loading dose of 8 mg/kg on Day 1 of Cycle 1, followed by 6 mg/kg on Day 1 of each subsequent 3-week cycle during neoadjuvant treatment.

DRUG

pegylated liposomal doxorubicin hydrochloride

Pegylated liposomal doxorubicin hydrochloride will be administered intravenously at 35 mg/m² on Day 1 of each 3-week cycle for the first 4 cycles of neoadjuvant treatment.

DRUG

Cyclophosphamide

Cyclophosphamide will be administered intravenously at 600 mg/m² on Day 1 of each 3-week cycle for the first 4 cycles of neoadjuvant treatment in combination with pegylated liposomal doxorubicin hydrochloride, pyrotinib, and trastuzumab.

DRUG

Paclitaxel for Injection Albumin Bound

Paclitaxel for injection albumin bound will be administered intravenously at 230-260 mg/m² on Day 1 of each 3-week cycle for the subsequent 4 cycles of neoadjuvant treatment in combination with pyrotinib and trastuzumab.
