Treatment Sequencing in HER2+ mBC: Real-World Data & Key Considerations in Third-Line Treatment Selection

Experts discuss treatment options for HER2-positive metastatic breast cancer following progression on trastuzumab deruxtecan (T-DXd), weighing real-world data on tucatinib-capecitabine-trastuzumab versus T-DM1, considering factors such as resistance mechanisms, administration preferences, and side effect management.

Video content above is prompted by the following:

What are the available treatment options after progression on trastuzumab deruxtecan (Tdxd), and how do real-world data support the use of tucatinib-based regimens or T-DM1?
How does the choice between tucatinib-capecitabine-trastuzumab (HER2CLIMB regimen) and T-DM1 depend on patient-specific factors such as toxicity, prior treatment exposure, and logistical considerations?
How do different mechanisms of HER2 inhibition influence treatment sequencing, and does prior exposure to tyrosine kinase inhibitors (TKIs) impact the efficacy of T-DM1?
