A Randomized Multicenter, Double-blind, Placebo-controlled Comparison of Chemotherapy Plus Trastuzumab Plus Placebo Versus Chemotherapy Plus Trastuzumab Plus Pertuzumab as Adjuvant Therapy in Patients With Operable HER2-positive Primary Breast Cancer (USON TOC4939G)

Study Description:

This randomized, double-blind, placebo-controlled, two-arm study will assess the safety and efficacy of pertuzumab in addition to chemotherapy plus Herceptin (trastuzumab) as adjuvant therapy in patients with operable HER2-positive primary breast cancer. After surgery, patients will be randomized to receive either pertuzumab or placebo intravenously (iv) every 3 weeks for one year, in addition to 6-8 cycles of chemotherapy and 1 year of Herceptin (trastuzumab) iv every 3 weeks. Anticipated time on study treatment is 52 weeks. This study will be carried out in collaboration with the Breast International Group (BIG).

Inclusion Criteria:

» Eastern Cooperative Oncology Group (ECOG) performance status </=1
» The interval between definitive surgery for breast cancer and randomization must be at least 3 weeks but no more than 7 weeks and the patient must be willing and able to start treatment within 1 week of randomization
