A Single-arm, Prospective, Open-label Phase II Clinical Study of Utidelone Combined With Bevacizumab in the Treatment of ≥ 2 Lines of HER-2 Negative Advanced Breast Cancer

This study is a prospective, single-arm, open-label phase II study to evaluate the efficacy and safety of the combination of Utidelone and bevacizumab regimen in patients with ≥ 2 lines of HER-2 negative advanced breast cancer.

Study Overview

• Status: Recruiting
• Conditions: HER-2 Negative Breast Cancer
• Intervention / Treatment: Drug: utidelone injection; Drug: Bevacizumab

Detailed Description

Patients included were patients with ≥ 2 lines of HER2-negative advanced breast cancer who had previously failed taxanes and/or anthracyclines, or patients with hormone receptor-positive HER2-negative advanced breast cancer who had progressed after at least 1 line of prior endocrine therapy.

This study used a Simon two-stage design. 71 subjects will be enrolled using the optimal design.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression free survival (PFS)	PFS is defined as the duration of time from first study treatment to disease progression or death from any cause as documented by the investigator	up to 2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective response rate (ORR)	Percentage of patients with a best investigator-assessed response of CR or PR from enrollment until disease progression as assessed by RECIST 1.1 compared with the total number of evaluable patients.	up to 2 years
Overall survival (OS)	OS is defined as the duration of time from first study treatment until death from any cause.	up to 3 years
Duration Of Response（DOR）	The assessment is conducted every two cycles. DOR is used to measure the time from the first occurrence of complete remission (CR) or partial remission (PR) in patients to the onset of disease progression (PD) or death due to any cause.	up to 2 years
Adverse Events（AEs）	An assessment is conducted once for each visit cycle.During each visit, all adverse events and laboratory indicators must be fully documented.	The research period lasts for two years, and the evaluation will continue until the completion of the research.
