A Randomized, Multicenter, Open-Label, Phase III Trial Comparing Trastuzumab Plus Pertuzumab Plus a Taxane Following Anthracyclines Versus Trastuzumab Emtansine Plus Pertuzumab Following Anthracyclines as Adjuvant Therapy in Patients With Operable HER2-Positive Primary Breast Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This two-arm, randomized, open-label, multicenter study will evaluate the efficacy and safety of trastuzumab emtansine in combination with pertuzumab versus trastuzumab in combination with pertuzumab and a taxane as adjuvant therapy in participants with human epidermal growth (HER) factor 2 (HER2)-positive primary invasive breast cancer. Following surgery and anthracycline-based chemotherapy, participants will receive either trastuzumab emtansine at a dose of 3.6 milligrams per kilogram (mg/kg) and pertuzumab at a dose of 420 milligrams (mg) intravenously (IV) every 3 weeks (q3w) or trastuzumab at a dose of 6 mg/kg and pertuzumab at a dose of 420 mg IV q3w in combination with a taxane.
