Background: We assessed health-related quality of life (symptoms of therapy/patient functioning/global health status), in APHINITY (pertuzumab/placebo, trastuzumab, and chemotherapy as adjuvant HER2-positive early breast cancer therapy).

Methods: Patients received 1 year/18 cycles of pertuzumab/placebo with trastuzumab and chemotherapy and completed EORTC QLQ-C30 and BR23 questionnaires until 36 months post-randomisation/disease recurrence. Changes ≥10 points from baseline were considered clinically meaningful.

Background: In the phase 3 MARIANNE trial, trastuzumab emtansine (T-DM1) with or without pertuzumab showed noninferior progression-free survival and better tolerability than trastuzumab plus a taxane (HT) for the first-line treatment of human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer. This article reports the final descriptive overall survival (OS) analysis, updated safety data, and additional patient-reported outcomes and biomarker analyses.

Methods: OS was assessed in 1095 patients with HER2-positive breast cancer and no prior therapy for advanced disease who had been randomized to HT, T-DM1 plus a placebo (hereafter T-DM1), or T-DM1 plus pertuzumab (T-DM1+pertuzumab).

Purpose Trastuzumab and pertuzumab are human epidermal growth factor receptor 2 (HER2) -targeted monoclonal antibodies, and trastuzumab emtansine (T-DM1) is an antibody-drug conjugate that combines the properties of trastuzumab with the cytotoxic activity of DM1. T-DM1 demonstrated encouraging efficacy and safety in a phase II study of patients with previously untreated HER2-positive metastatic breast cancer. Combination T-DM1 and pertuzumab showed synergistic activity in cell culture models and had an acceptable safety profile in a phase Ib and II study.
