Brief Summary

This study is designed to comprehensively evaluate the HER2 positive recurrent/metastatic breast cancer patients in the real world who receive the combination of Inetetamab and Paclitaxel ± Pertuzumab, including basic characteristics, efficacy and safety. The results of this study are helpful to further understand the efficacy and safety of HER2 positive patients with recurrent/metastatic breast cancer who receive the combination of Inetetamab and Paclitaxel ± Pertuzumab in the first line, and help clinical decision-making.

Conditions

Breast Cancer Stage IV

Secondary Outcomes (4)

• Objective Response Rate (ORR)

  Until progression, assessed up to approximately 24 months

• Clinical Benefit Rate (CBR)

  Until progression or death, assessed up to approximately 24 months

• Overall Survival (OS)

• Number of Participants With Adverse Events (AEs)

  Up to approximately 3 years

Study Arms (1)

Inetetamab and Paclitaxel ± Pertuzumab

EXPERIMENTAL

Inetetamab and Paclitaxel ± Pertuzumab Inetetamab：was administered as an intravenous (IV) loading dose of 8mg/kg q3w on Day 1 of Cycle 1 (1 Cycle length = 21 days), and 6mg/kg q3w on Day 1 of subsequent cycles, until investigator-assessed radiographic or clinical progressive disease, unmanageable toxicity, or study termination. Paclitaxel：Docetaxel 75mg/m2, albumin paclitaxel 260mg/m2, or paclitaxel liposomes 175mg/m2) is administered intravenously on the first day of every three weeks, until investigator-assessed radiographic or clinical progressive disease, unmanageable toxicity, or study termination. Pertuzumab：was administered as an intravenous (IV) loading dose of 840mg q3w on Day 1 of Cycle 1 (1 Cycle length = 21 days), and 420mg q3w on Day 1 of subsequent cycles, until investigator-assessed radiographic or clinical progressive disease, unmanageable toxicity, or study termination.

You may qualify if:

• Age 18 - 70 years, female
• Patients with HER2-positive breast cancer defined as immunohistochemical (IHC) test + + +, or FISH test positive
• Participants must have histologically or cytologically confirmed invasive breast cancer with locally recurrent inoperable or radiological evidence of metastatic disease
• Have not received first-line anti-HER2 treatment or (neo) adjuvant anti-HER2 drug treatment that is effective and has been discontinued for more than 12 months
• Patients with assessable target lesion as per RECIST 1.1 and irRECIST criteria;
• ECOG PS score 0 or 1, estimated survival time ≥3 months, and can be followed-up;
• The cardiopulmonary function is basically normal, with LVEF ≥ 50%;
• Adequate organ function;
• Female patients of childbearing age who have negative pregnancy tests and voluntarily adopt effective and reliable contraceptive measures；
• The patient voluntarily signs an informed consent form.

You may not qualify if:

• Participated in other clinical trials within 4 weeks;
• Have received any systematic anti-tumor treatment during the recurrence/metastasis stage (excluding endocrine therapy previously performed for recurrence/metastasis stage);
• During the (neo) adjuvant phase, other anti-HER2 treatments were received in addition to trastuzumab and pertuzumab;
• Patients who experience disease progression during (neo) adjuvant trastuzumab treatment, as well as patients who experience recurrence/metastasis within 12 months after completing (neo) adjuvant system treatment;
• Evidence of central nervous system metastasis or leptomeningeal disease;
• Individuals with a known history of allergies to the components of this medication regimen;
• Pregnant or lactating women;
• Left ventricular ejection fraction\<50% for cardiac function; Patients with obvious clinical manifestations such as arrhythmia, myocardial ischemia, severe atrioventricular block, heart dysfunction, and severe heart valve disease;
• The researchers believe that it is not appropriate to participate in this trial, as any other medical, social, or psychological factors may affect safety or compliance with research procedures.
