Pyrotinib Plus Capecitabine for Adjuvant Treatment of HER2 Positive Early-stage Breast Cancer

Официальное название

A Prospective, Multicenter and Registry-based Cohort Study of Pyrotinib Plus Capecitabine for Adjuvant Treatment of HER2 Positive Early-stage Breast Cancer

Обзор

This is a prospective, multicenter, registry-based cohort study to explore the efficacy and safety of Pyrotinib combined with Capecitabine for adjuvant treatment of HER2 positive early breast cancer compared with treatment of physician's choice. Pyrotinib is a small molecule tyrosine kinase inhibitor which can irreversibly inhibit HER1, HER2, and HER4.

Критерии включения

• Female patients ≥ 18 years and ≤ 75 years old;
• Primary invasive breast cancer confirmed by histology;
• HER2 positive breast cancer (IHC 3+, or IHC 2+ and FISH positive); lymph node positive, except for T0; lymph node negative and tumor >1cm, or tumor > 0.5 cm and ≤ 1cm, and accompanied by any of the following high-risk factors: pathological grade 3, ER/PR negative, or < 35 years old;
• Having received mastectomy or breast conserving surgery, and received sentinel lymph node biopsy or axillary lymph node dissection, and within 90 days from the breast surgery;
• With known ER/PR status of breast cancer;
• ECOG score 0-1;
• The patient's major organ functions meet all of the following requirements for blood tests:

• Neutrophil count (ANC) ≥ 1,500/mm3 (1.5×109/L);
• Platelet count (PLT) ≥ 75,000/mm3 (75×109/L);
• Hemoglobin (Hb) ≥ 8 g/dL (80 g/L);
• Serum creatinine (SCr) ≤ 1.5 times the upper limit of normal (ULN) or creatinine clearance ≥ 60 mL/min;
• Total bilirubin (TBIL) ≤ 1.5 times the upper limit of normal (ULN);
• Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level ≤ 2.5 times the upper limit of normal (ULN), patients with liver metastases should be ≤ 5×ULN.

Критерии исключения

• Breast cancer recurs before enrollment, or local recurrence/ metastasis confirmed by radiology;
• The subject has participated in other clinical trials within 4 weeks or 5 half-lives (whichever is longer) before enrollment;
• The patient has previously received treatment including tyrosine kinase inhibitors targeting HER2 (e.g., lapatinib, neratinib, and pyrotinib);
• The patient has been diagnosed with other malignancies within 5 years of enrollment, except for cervical carcinoma in situ, basal cell carcinoma of the skin, or squamous cell carcinoma of the skin which has been cured;
• The patient is receiving anti-tumor therapies from other clinical trials;
• Inability to swallow, chronic diarrhea, or intestinal obstruction, with multiple factors affecting drug administration and absorption;
• The patient has undergone major surgical procedures unrelated to breast cancer within 4 weeks of enrollment, or has not fully recovered from such surgical procedures;
• With known allergies to any components of the agents to be administered in this study; history of acquired or congenital immunodeficiency diseases, including HIV; history of HCV, active hepatitis B, or history of organ transplantation;
