DESTINY Breast09 Topline Findings in First-Line HER2 Positive Metastatic Breast Cancer
This segment highlights the interim topline efficacy findings from DESTINY Breast09 and explores their potential implications for first-line treatment of HER2 positive metastatic breast cancer. The discussion summarizes progression-free survival signals observed with trastuzumab deruxtecan with or without pertuzumab compared with the historical standard regimen of docetaxel, trastuzumab, and pertuzumab. Panelists emphasize that these results represent an early data readout and should be interpreted cautiously pending peer-reviewed publication, mature follow-up, and formal guideline integration. The conversation focuses on how these findings may challenge existing first-line paradigms by introducing an antibody drug conjugate earlier in the disease course, while reinforcing the importance of contextualizing DB09 within the broader HER2 evidence base. This segment sets the stage for subsequent discussion on safety, durability of benefit, and how emerging data may ultimately influence clinical practice once fully validated.
