NCT01358877

  Purpose

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 pert uzumab 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).

  • Overall survival (OS) [ Time Frame: up to 13 years ] [ Designated as safety issue: No ]
  • Recurrence-free interval (RFI): time between randomization and local, regional or distant breast cancer recurrence [ Time Frame: up to 13 years ] [ Designated as safety issue: No ]
  • Distant recurrence-free interval (DRFI): time between randomization and distant breast cancer recurrence [ Time Frame: up to 13 years ] [ Designated as safety issue: No ]
  • Cardiac and overall safety: Incidence of adverse events [ Time Frame: up to 13 years ] [ Designated as safety issue: No ]
  • Quality of life: EORTC QLQ-C30, QLQ-BR23 and EQ-5D questionnaires [ Time Frame: up to 3 years ] [ Designated as safety issue: No ]
