Perjeta (pertuzumab) [package insert]. FDA. 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.
Phesgo (pertuzumab and trastuzumab) [package insert]. FDA. The U.S. Food and Drug Administration granted approval to Phesgo (pertuzumab and trastuzumab) in combination with 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. The FeDeriCa study (NCT03493854) demonstrated comparable pharmacokinetics and safety profiles between Phesgo and intravenous pertuzumab and intravenous trastuzumab.
