研究目的:

本研究旨在通过在既往接受过标准一线治疗后进展的晚期转移性乳腺癌患者中研究后线抗肿瘤治疗联用PCSK9单抗(托莱西单抗)的有效性和安全性,为晚期乳腺癌的治疗开辟新的思路。  

Objectives of Study:

This study aims to investigate the efficacy and safety of combining a PCSK9 monoclonal antibody (Tolescevimab) with subsequent-line antitumor therapy in patients with advanced metastatic breast cancer who have progressed after prior first-line standard treatment, thereby exploring novel therapeutic strategies for advanced breast cancer.
