Erika Hamilton, SABCS 2022: Trastuzumab deruxtecan and trastuzumab deruxtecan + pertuzumab in HER2+ metastatic breast cancer

Published Online: January 9th 2023

Preclinical findings have suggested that when used in combination with anticancer treatments, trastuzumab deruxtecan (T-Dxd) could improve treatment efficacy in HER2+ metastatic breast cancer (mBC).

In this interview we discuss with Dr Erika Hamilton (Sarah Cannon Research Institute, Tennessee Oncology, Nashville, TN) preliminary data from the dose expansion phase of the DESTINY-Breast07 (DB-07) (NCT04538742) trial. DB-07 is an open label, phase 1b/2 study investigating T-Dxd monotherapy vs. T-Dxd + pertuzumab as first line treatment in mBC. The primary objective of the dose expansion part of the trial was to assess safety and tolerability.

The abstract entitled ‘Dose-expansion study of Trastuzumab Deruxtecan as monotherapy or combined with Pertuzumab in patients With metastatic human epidermal growth factor receptor 2-positive (HER2+) breast cancer in DESTINY-Breast07 (DB-07)’ was presented at San Antonio Breast Cancer Symposium (SABCS), 06–10, December, 2022.
