A Two-cohort, Open-label, Multicenter Phase II Trial Assessing the Efficacy and Safety of Pertuzumab Given in Combination With Trastuzumab and Vinorelbine in First Line Patients With HER2-positive Advanced (Metastatic or Locally Advanced) Breast Cancer.

This two-cohort, open-label, multicenter, phase II study will assess the safety and efficacy of pertuzumab given in combination with Herceptin (trastuzumab) and vinorelbine in first line in patients with metastatic or locally advanced HER2-positive breast cancer. Patients will receive pertuzumab 840 mg and Herceptin 8 mg/kg administered sequentially as separate iv infusions on Days 1 and 2, respectively, of Cycle 1. From Cycle 2 onwards, patients will receive pertuzumab 420 mg and Herceptin 6 mg/kg, administered either sequentially as separate iv infusions on Day 1 and Day 1 or 2, respectively (Cohort 1) or together in one infusion bag on Day 1 (Cohort 2) every 3 weeks. Vinorelbine will be administered at 25 mg/m2 iv on Days 2 and 9 of Cycle 1, and at 30-35 mg/m2 on Days 1 and 8 (or Days 2 and 9) of each following 3-week cycle. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs, or withdrawal of consent or death.

Stanford is not currently accepting new patients for this trial. You may want to check clinicaltrials.gov to see if other locations are recruiting.
