• Interventions: Drug: Apatinib Mesylate; Drug: Albumin-Bound Paclitaxel

• Registration Number: NCT05019690
• Lead Sponsor: Fujian Cancer Hospital

Brief Summary

This study is a single-arm,exploratory clinical study, to evaluate the effectiveness and safety of apatinib mesylate combined with albumin-bound paclitaxel for second-line treatment of advanced triple negative breast cancer.

Detailed Description

This is a exploratory, single-arm, open-label trial. The investigator's primary purpose is to explore that PFS and safety of apatinib combined with albumin-bound paclitaxel for treatment of advanced triple negative breast cancer.

In treatment period, patients will be administrated apatinib plus albumin-bound paclitaxel, every 21 days for 1 cycle, until disease progression, toxicity intolerance, withdrawal of informed consent, patients judged must be terminated study termination.

The imaging evaluation was performed according to the RECIST 1.1 criteria every 6 weeks.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Apatinib Combined With Albumin-Bound Paclitaxel	Apatinib Mesylate	Participants will receive apatinib combined with albumin-bound paclitaxel until predefined study end, disease progression, unacceptable toxicity, withdrawal of consent or death, whichever occurs first.
Apatinib Combined With Albumin-Bound Paclitaxel	Albumin-Bound Paclitaxel	Participants will receive apatinib combined with albumin-bound paclitaxel until predefined study end, disease progression, unacceptable toxicity, withdrawal of consent or death, whichever occurs first.

Primary Outcome Measures

Name	Time	Method
Progression-Free Survival(PFS)	From enrollment to 12 month	PFS was defined as the time from randomization to first documented disease progression (PD) using Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) or death from any cause, whichever occurred first. For target lesions, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum of the longest diameter recorded since treatment started or the appearance of 1 or more new lesions. For non-target lesions, PD was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions.; The PFS will be will be estimated using Kaplan-Meier method. A Kaplan-Meier curve, median PFS, hazard ratio with appropriate confidence intervals will be reported.

Secondary Outcome Measures

Name	Time	Method
Objective response rate(ORR)	From enrollment to 12 month	ORR was defined as percentage of participants with best (confirmed) overall response (BOR) of either CR or PR. ORR was assessed by the investigator according to RECIST version 1.1 and is based on BOR, which is defined as best response recorded from start of study treatment until disease progression/recurrence or death. Participants needed to have two consecutive assessments of PR or CR to be a responder. Only participants with measurable disease at baseline were included in the analysis of BOR and who did not have any evaluable post-baseline assessments were classified as not evaluable.; The ORR will be reported by percentage with each arms and appropriate confidence intervals.
Overall Survival (OS)	From enrollment to 24 month	Overall Survival (OS), defined as the time from the date of randomization to the date of death, regardless of the cause of death. Participants who were alive at the time of the analysis were censored at the date of the last follow-up assessment. Participants without follow-up assessment were censored at the day of last study medication and participants with no post-baseline information were censored at the date of randomization.; The OS will be will be estimated using Kaplan-Meier method. A Kaplan-Meier curve, median OS, hazard ratio with appropriate confidence intervals will be reported.
Disease control rate(DCR)	From enrollment to 12 month	DCR was defined as percentage of participants with best (confirmed) overall response (BOR) of either CR or PR or SD. DCR was assessed by the investigator according to RECIST version 1.1 and is based on BOR, which is defined as best response recorded from start of study treatment until disease progression/recurrence or death. Participants needed to have two consecutive assessments of PR or CR or SD to be a responder. Only participants with measurable disease at baseline were included in the analysis of BOR and who did not have any evaluable post-baseline assessments were classified as not evaluable.; The DCR will be reported by percentage with each arms and appropriate confidence intervals.; \[Time Frame: From enrollment to 12 month\]
