Detailed Description

This is a randomized, open label Phase II-III neoadjuvant study comparing the efficacy and safety of ARX788 combined with pyrotinib maleate versus TCBHP (trastuzumab plus pertuzumab with docetaxel and carboplatin) in patients with HER2-positive breast cancer. Patients will be randomized (1:1) to one of the two treatment arms: arm 1, ARX788 plus pyrotinib maleate for 6 cycles; arm 2, trastuzumab plus pertuzumab with docetaxel and carboplatin for six cycles. Patients will undergo surgery after neoadjuvant therapy. Efficacy will be assessed every 2 cycles.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Total pathological complete response rate (tpCR) rate
Time Frame: 3 years
The standard for removal of breast and lymph node tumors which means there are no infiltrating cancer cells at the primary breast and axillary lymph nodes, and only intraductal cancer is allowed on the breast.
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Five-year overall survival (OS)
Time Frame: 5 years
The time from the random date to death due to any cause.
5 years
Adverse events (AE)
Time Frame: 3 years
Adverse events (AE) will be assessed as per the NCI-CTC AE 5.0 standard.
3 years
Breast pathological complete response rate (bpCR) rate
Time Frame: 3 years
The standard for breast tumor removal which means that there are only infiltrating cancer cells at the primary breast tumor site.
3 years
Residual tumor burden (RCB)
Time Frame: 3 years
Postoperative pathological results will be used to assess the residual tumor area of primary breast tumor (area in mm×mm), the cell density of the residual tumor（cell density in percentages）, the proportion of carcinoma in situ (proportion of carcinoma in percentages), the number of positive lymph nodes and the diameter of largest metastasis with residual nodes (diameter in mm). The RCB class can be estimated from the above five pathological parameters through a network calculation: RCB-0 in grades: pCR; RCB-I in grades: minimal residual tumor; RCB-II: moderate residual tumor; RCB-III in grades: extensive residual tumor.
3 years
Best overall response rate (BORR)
Time Frame: 3 years
The proportion of patients who achieve remission at any point during the study.
3 years
Event-free survival (EFS)
Time Frame: 3 years
The time from the day of enrollment to the first occurrence of recurrent disease, including second primary malignancies in the non-breast area and breast ductal carcinoma in situ.
3 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Health-related quality of life (HRQOL)
Time Frame: 3 years
The European Organization for Research and Treatment-QOL questionnaire and breast cancer specific module (EORTC QLQ-C30 and QLQ-BR23) will use to measure the HRQOL. Compare each domain scores and global health/quality-of-life score of EORTC QLQ-C30 with baseline, and compare each domain scores of EORTC QLQ-BR23 with baseline.
