UTD1 Combined With Capecitabine in Metastatic HER2-negative Breast Cancer Patients With Brain Metastases
Study Details
Study Description
Brief Summary
This study is a single-arm, multicenter, open-labeled clinical study of UTD1 combined with Capecitabine in metastatic HER2-negative breast cancaner patients with brain metastases. This study aims to evaluate the efficacy and safety of UDT1 combined with capecitabine in metastatic HER2-negative breast cancer patients with brain metastases.

Outcome Measures
Primary Outcome Measures
- CNS-Objective Response Rate (ORR) [From the enrollment to the progression of all CNS target lesions assessed according to RANOBM standard up to 1 year.]
The proportion of patients with complete remission (CR) and partial remission (PR) as the best efficacy evaluation in the total number of evaluable patients observed during the process from enrollment to the progression of all CNS target lesions assessed according to the RANOBM criteria.
Secondary Outcome Measures
- CNS clinical benefit rate (CNS-CBR) [From the enrollment to the progression of all CNS target lesions assessed according to RANOBM standard up to 1 year.]
The percentage of patients who achieved complete response (CR), partial response (PR) or disease stability (SD) as the best efficacy evaluation in the total number of evaluable patients observed from enrollment to all CNS target lesions assessed according to the RANOBM criteria.
- CNS progression free survival (CNS-PFS) [From enrollment to the first imaging confirmed disease progression (PD) of all central nervous system target lesions (RANOBM criteria) or death due to any cause without progression recorded up to 1 year.]
The time from enrollment to the first imaging confirmed disease progression (PD) of all central nervous system target lesions (RANOBM criteria) or death due to any cause without progression recorded.
- CNS objective response rate (CNS-ORR) [From the enrollment to the progression of all CNS target lesions assessed according to RECIST 1.1 standard up to 1 year.]
The proportion of patients with complete remission (CR) and partial remission (PR) as the best efficacy evaluation in the total number of evaluable patients observed during the process from enrollment to the progression of all CNS target lesions assessed according to the RECIST 1.1 criteria.
- Objective response rate (ORR) [From the enrollment to the progression of all CNS target lesions assessed according to RECIST standard up to 1 year.]
According to RECIST 1.1 criteria, the number of patients with the best efficacy evaluation of CR or PR during the process from enrollment to disease progression accounts for the proportion of the total number of evaluable patients.
- Progressive survival (PFS) [From the enrollment to the progression of all CNS target lesions assessed according to RECIST standard up to 1 year.]
The time from enrollment and disease progression (PD) confirmed by imaging from enrollment to the first time (RECIST 1.1 criteria) or death without progress is recorded but due to any cause.
