Brief Summary

This study aims to investigate the efficacy and safety of utidelone in combination with bevacizumab in the treatment of advanced breast cancer with brain metastases, and thus provides a new systemic treatment strategy for those patients.

Detailed Description

This is a multicenter,open label, phase 2 trial to investigate the efficacy and safety of utidelone in combination with bevacizumab in the treatment of advanced breast cancer with brain metastases. Patients with HER2-negative advanced breast cancer who have received at least one prior anthracycline and one prior taxane or HER2-positive advanced breast cancer who have failed trastuzumab and pyrotinib, and with at least one measurable CNS lesion are eligible for the study.

This study includes 2 cohorts, and the Simon two-stage design are applied, respectively. A total of 48 patients with HER2-negative advanced breast cancer are included in cohort 1, and 52 patients with HER-2 positive patients are enrolled in cohort 2. Patients in both cohorts receive bevacizumab, 15mg/kg, day 1, and utidelone, 30mg/m2 (±10%), day 1-5 every 3-week cycle until disease progression or unmanageable toxicity. The primary endpoint is CNS-ORR according to the RECIST 1.1. The secondary endpoints include CNS-ORR according to RANO criteria, CNS-PFS assessed by investigator, extracranial ORR, extracranial PFS, OS, time to WBRT, quality of life and safety profile according to NCI-CTCAE 5.0.
