Pyrotinib and Nab-Paclitaxel in HER2-Positive Breast Cancer (PANHER Trial): A Prospective, Single-Arm, Phase II Trial.

ABSTRACT: Trastuzumab and pertuzumab combined with chemotherapy represent the standard therapy for first-line treatment of HER2-positive metastatic breast cancer (BC). Due to challenges related to availability and cost in China, it is necessary to explore treatments involving tyrosine kinase inhibitors (TKIs). In this multicenter, single-arm, open-label phase II trial, patients with HER2-positive BC were enrolled from seven hospitals in China. Patients received oral pyrotinib 400 mg once daily and intravenous nab-paclitaxel 125 mg/m² on days 1, 8, and 15 of each 28-day cycle until disease progression or intolerable toxicity.
