How do you sequence everolimus/endocrine therapy versus fam-trastuzumab deruxtecan after progression on CDK4/6i in metastatic ER+ HER2 low breast cancer?

After progression on CDK4/6i + ET, how would you sequence everolimus vs T-DXd in HR+/HER2-low metastatic breast cancer?

• Everolimus + ET first, then T-DXd at progression of disease
• T-DXd first, then Everolimus + ET at progression of disease
• T-DXd first, then other agents at progression because I don't routinely use everolimus + ET
• Everolimus + ET first, then other agents at progression because I don't routinely use T-DXd
• Other
