Study Details
Study Description
Brief Summary
The study is designed to explore the clinical benefit following treatment with tucidinosta in combination with metronomic capecitabine and endocrine therapy in patients with hormone receptor-positive, Her2-negative advanced breast cancer who have received CDK4/6 Inhibitor treatment.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tucidinosta+Metronomic Capecitabine+Endocrine Therapy This arm is divided into two groups. The main difference of this two groups lies in the selection of endocrine therapy. One is supposed to choose aromatase inhibitor, and the other is fulvestrant. The principle of making choice is based on the history of endocrine drug use. |

Outcome Measures
Primary Outcome Measures
- Objective Response Rate [Up to 3 years]
Objective response is defined as a complete response (CR) or partial response (PR) according to RECIST v.1.1 recorded from randomization until disease progression or death due to any cause
Secondary Outcome Measures
- Progress-free survival [Up to 3 years]
Time from randomization to the first documentation of objective tumor progression or to death due to any cause.
- Disease Control Rate [Up to 3 years]
Disease control is defined as complete response (CR), partial response (PR), or stable disease (SD) ≥24 weeks according to the RECIST version 1.1 recorded in the time period between randomization and disease progression or death to any cause.
- Overall Survival [Up to 3 years]
Time from randomization to date of death due to any cause. according to the RECIST version 1.1 recorded in the time period between randomization and disease progression or death to any cause.
