A Study of Pertuzumab and Trastuzumab Subcutaneous (SC) Treatment in Combination With a Taxane in Participants With Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Metastatic Breast Cancer

Summary

This open-label, multicenter, Phase IIIb study will assess the safety, tolerability and efficacy of a combination therapy of intravenous (IV) pertuzumab (Perjeta), trastuzumab (Herceptin) SC, and taxane chemotherapy (docetaxel, paclitaxel or nab-paclitaxel) as first-line therapy in participants with HER2-positive metastatic breast cancer (mBC). All participants will be treated with 3-week cycles of pertuzumab IV (840 milligrams \[mg\] first dose; subsequent doses of 420 mg) and trastuzumab SC (600 milligrams \[mg\]). The taxane treatment regimen will be determined by the investigator. Participants will continue therapy until disease progression, unacceptable toxicity, or the participant withdraws consent, whichever occurs first.
