A Randomized, Multicenter, Double-Blind, Placebo-Controlled, Phase III Study to Evaluate Pertuzumab in Combination With Docetaxel and Trastuzumab as Neoadjuvant Therapy, and Pertuzumab in Combination With Trastuzumab as Adjuvant Therapy After Surgery and Chemotherapy in Patients With Early-Stage or Locally Advanced HER2-Positive Breast Cancer
In Brief
A Phase 3 clinical trial evaluating FEC Chemotherapy, Surgery, and 4 other interventions for Breast Cancer. Completed, enrolled 329 participants across 23 sites in 4 countries.
Detailed Summary
This is an Asia-Pacific regional, randomized, double-blind, multicenter trial designed to evaluate treatment with trastuzumab + pertuzumab + docetaxel compared with trastuzumab + placebo + docetaxel in chemotherapy-naïve participants with early-stage or locally advanced HER2-positive breast cancer.

Fluorouracil 500-600 milligrams per square meter (mg/m2), epirubicin 90-120 mg/m2, and cyclophosphamide 500-600 mg/m2 by intravenous (IV) infusion every 3 weeks for three cycles (Cycles 5-7). FEC chemotherapeutic agents will be administered following surgery on Day 1 of each specified cycle.
All participants who are eligible for surgery will undergo surgery and have their pathologic response evaluated.
Docetaxel IV infusion in 3-week cycles. Neoadjuvant treatment: 75 mg/m2 for Cycles 1-4.
Pertuzumab IV infusion in 3-week cycles. Prior to surgery (neoadjuvant treatment): 840 milligrams (mg) loading dose for Cycle 1, followed by 420 mg for Cycles 2-4. After surgery and 3 cycles of FEC chemotherapy (adjuvant treatment): 840 mg loading dose for Cycle 8, followed by 420 mg for Cycles 9-20)
Placebo by IV infusion in 3-week cycles as neoadjuvant treatment (Cycles 1-4)and as adjuvant treatment (Cycles 8-20)
Trastuzumab IV infusion in 3-week cycles. Neoadjuvant treatment: 8 milligrams per kilogram (mg/kg) loading dose for Cycle 1, followed by 6 mg/kg for Cycles 2-4. Adjuvant treatment: 8 mg/kg loading dose for Cycle 8, followed by 6 mg/kg for Cycles 9-20.
