A UK Real-world Evaluation of Efficacy and Toxicity of Second-line Trastuzumab Emtansine and Third-line Trastuzumab Deruxtecan in HER2-positive Advanced Breast Cancer

Purpose: Trastuzumab emtansine is routinely offered to patients in the second-line setting for advanced human epidermal growth factor receptor 2 (HER-2)-positive breast cancers. There is a paucity of UK real-world data on the progression-free survival (PFS) with trastuzumab emtansine therapy after prior pertuzumab and the risk of cardiotoxicity. Trastuzumab deruxtecan is currently approved for use after 2 or more anti-HER2 therapies based on DESTINY-Breast01 single-arm trial showing an overall response rate of 60.9% and median PFS of 16.4 [1].
