PLD-cyclophosphamide-Nab-P Continuously Combined With Dual HER2 Blockage for HER2-positive Breast Cancer

PLD Plus Cyclophosphamide Followed by Nab-paclitaxel (Nab-P) as Primary Chemotherapy Continuously Combined With Dual HER2 Blockage for HER2-positive Breast Cancer: A Single-arm Phase 2 Trial(Brecan Trial)

patients with HER2-positive breast cancer (cT2-3/N0-1/M0) were treated with PldCHP (pegylated liposomal doxorubicin 35mg/m2, cyclophosphamide 600mg/m2, trastuzumab 8 mg/kg loading, then 6 mg/kg, pertuzumab 840 mg loading, then 420 mg, iv, q3w) for 4 cycles followed by Nab-PHP (Nab-Paclitaxel 260mg/m2, trastuzumab 6 mg/kg, pertuzumab 420 mg, iv, q3w) for 4 cycles

Study Overview

• Status: Recruiting
• Conditions: Breast Cancer; HER2-positive Breast Cancer
• Intervention / Treatment: Drug: pegylated liposomal doxorubicin (PLD) plus cyclophosphamide followed by Nab-paclitaxel (Nab-P) ,continuously combined with dual HER2 blockage

Detailed Description

Upon approval by the Medical Ethics Committee of Xijing Hospital, patients with HER2-positive breast cancer (cT2-3/N0-1/M0) receiving neoadjuvant therapy, were enrolled. The patients were treated with PldCHP (pegylated liposomal doxorubicin 35mg/m2, cyclophosphamide 600mg/m2, trastuzumab 8 mg/kg loading, then 6 mg/kg, pertuzumab 840 mg loading, then 420 mg, iv, q3w) for 4 cycles followed by Nab-PHP (Nab-Paclitaxel 260mg/m2, trastuzumab 6 mg/kg, pertuzumab 420 mg, iv, q3w) for 4 cycles, with strict monitoring of cardiotoxicity. The primary endpoint was pCR rate, and secondary endpoints were cardiac safety during neoadjuvant therapy.
