A Study of Pertuzumab in Addition to Chemotherapy and Herceptin (Trastuzumab) as Adjuvant Therapy in Patients With HER2-Positive Primary Breast Cancer

Overview

About this study

This randomized, double-blind, placebo-controlled, two-arm study will assess the safety and efficacy of pertuzumab in addition to chemotherapy plus Herceptin (t rastuzumab) 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 wee ks. Anticipated time on study treatment is 52 weeks. This study will be carried out in collaboration with the Breast International Group (BIG).
