Therapeutic Response Statement (Sensitivity)
This therapeutic response statement supports the relationship that HER2-positive status confers therapeutic sensitivity to Capecitabine, Lapatinib in patients with Invasive Breast Carcinoma.
The U.S. Food and Drug Administration granted approval to lapatinib in combination with capecitabine for the treatment of patients with advanced or metastatic breast cancer whose tumors overexpress human epidermal growth factor 2 (HER2) and who have received prior therapy, including an anthracycline, a taxane, a trastuzumab.
This statement is based on a regulatory approval from the Food and Drug Administration:
TYKERB is a kinase inhibitor indicated in combination with capecitabine for the treatment of patients with advanced or metastatic breast cancer whose tumors overexpress human epidermal growth factor receptor 2 (HER2) and who have received prior therapy, including an anthracycline, a taxane, and trastuzumab. Limitations of Use: Patients should have disease progression on trastuzumab prior to initiation of treatment with TYKERB in combination with capecitabine. TYKERB in combination with an aromatase inhibitor has not been compared to a trastuzumab-containing chemotherapy regimen for the treatment of metastatic breast cancer.
