Popis
Inclusion Criteria:
- Aged ≥ 18 years old;
- Histopathologically confirmed HER2-positive inoperable locally advanced or metastatic breast cancer;
Patients with first-line or second-line advanced disease:
First-line advanced disease: no prior systemic therapy for locally advanced or metastatic disease. For patients who received neoadjuvant or adjuvant therapy, the disease-free interval (DFI) after the completion of the last chemotherapy or HER2-targeted therapy was more than 12 months; Second-line advanced disease: prior treatment with taxane combined with trastuzumab, with or without pertuzumab, in the advanced setting; or recurrence occurring during neoadjuvant/adjuvant therapy, or a disease-free interval (DFI) of ≤ 12 months after completion of the last neoadjuvant/adjuvant chemotherapy and HER2-targeted therapy;
- Planned to receive pyrotinib-containing regimen, and judged by investigators based on clinical practice to have potential subsequent treatment with Ruikang trastuzumab after failure of pyrotinib-containing therapy;
- Traceable medical records available throughout the treatment period.
Exclusion Criteria:
- Failure to sign the informed consent form;
- Pregnant or lactating females;
- Patients participating in any interventional clinical trial involving investigational drugs or marketed drugs at enrollment;
- Other conditions deemed ineligible for enrollment by the investigator's judgment.

Experimentální: Cohort A
This cohort consists of patients with first-line advanced disease.
First-line advanced disease is defined as no prior systemic therapy administered for locally advanced or metastatic disease.
For patients who have received neoadjuvant or adjuvant therapy, the disease-free interval (DFI) after the completion of the last chemotherapy or HER2-targeted therapy must be longer than 12 months.
First-line patients receive treatment with pyrotinib plus trastuzumab combined with chemotherapy.
Upon disease progression or intolerance to pyrotinib-containing regimens, subsequent treatment with Trastuzumab Rezetecan will be administered.
|
Pyrotinib: administered orally once daily at a dose of 400 mg, 320 mg or 240 mg within 30 minutes after breakfast.
A continuous administration of 21 days is defined as one treatment cycle.
The dosage of pyrotinib will be adjusted by physicians according to the individual clinical conditions.
Concomitant chemotherapeutic agents and other supportive care treatments are determined at the investigators' discretion in accordance with clinical practice guidelines and drug instructions.
Trastuzumab Rezetecan: administered intravenously at a dose of 4.8 mg/kg on Day 1 of each cycle, with a 21-day treatment cycle.
|
|
Experimentální: Cohort B
This cohort includes patients with second-line advanced breast cancer.
Second-line advanced disease is defined as prior receipt of taxane combined with trastuzumab, with or without pertuzumab, in the advanced setting; or disease recurrence during neoadjuvant/adjuvant therapy, or a disease-free interval (DFI) of ≤ 12 months after completion of the last cycle of neoadjuvant/adjuvant chemotherapy and HER2-targeted therapy.
Patients in the second-line setting are treated with pyrotinib plus capecitabine.
Following disease progression or intolerance to pyrotinib-containing regimens, subsequent treatment with Trastuzumab Rezetecan is administered.

Pyrotinib: administered orally once daily at a dose of 400 mg, 320 mg or 240 mg within 30 minutes after breakfast.
