研究目的: |
主要研究目标:评估T-DXd在HER2低表达晚期乳腺癌伴脑转移患者中的颅内客观缓解率(基于神经肿瘤标准);次要研究目标:评估颅内和全身的无进展生存期、总生存期;描述T-DXd在该人群中的安全性特征;探索不同生物标志物亚组的疗效差异。 |
||||||||||||||||||||||
|
Objectives of Study: |
Primary study objective: To evaluate the intracranial objective response rate of T-DXd in patients with HER2-low advanced breast cancer and brain metastases (based on Response Assessment in Neuro-Oncology criteria); Secondary study objectives: To evaluate intracranial and systemic progression-free survival and overall survival; To describe the safety profile of T-DXd in this patient population; To explore efficacy differences across different biomarker subgroups. |
