Therapeutic Response Statement (Sensitivity)
This therapeutic response statement supports the relationship that HER2-positive status confers therapeutic sensitivity to Cyclophosphamide, Epirubicin, Paclitaxel, Pertuzumab, Trastuzumab in patients with Invasive Breast Carcinoma.
The U.S. Food and Drug Administration granted approval to pertuzumab in combination with trastuzumab and chemotherapy for the adjuvant treatment of patients with HER2-positive early breast cancer at high risk of recurrence. This indication is based on Aphinity (NCT01358877) a multicenter, randomized, double-blind, placebo-controlled study where patients received one of the following anthracycline-based or non-anthracycline-based chemotherapy regimens: (1) cyclophosphamide, epirubicin, docetaxel, 5-fu; (2) cyclophosphamide, epirubicin, paclitaxel, 5-fu; (3) cyclophosphamide, doxorubicin, docetaxel, 5-fu; (4) cyclophosphamide, doxorubicin, paclitaxel, 5-fu; (5) doxorubicin, cyclophosphamide, docetaxel; (6) epirubicin, cyclophosphamide, docetaxel; (7) doxorubicin, cyclophosphamide, paclitaxel; (8) epirubicin, cyclophosphamide, paclitaxel; (9) carboplatin, docetaxel.
This statement is based on a regulatory approval from the Food and Drug Administration:
PHESGO is a combination of pertuzumab and trastuzumab, HER2/neu receptor antagonists, and hyaluronidase, an endoglycosidase, indicated for use in combination with chemotherapy as adjuvant treatment of patients with HER2-positive early breast cancer at high risk of recurrence.
