How do you approach patients that develop atopic dermatitis while on biologics for psoriasis?

I have an elderly patient with a history of biopsy-proven psoriasis on IL-17 biologic therapy. She has developed an intense itch without a primary rash that has not improved with topicals and workup has been unremarkable. Any contraindications to starting Dupixent? We are aware of a publication in JAAD that studied the concomitant administration of dual-biologic therapies (Brumfiel et al., PMID 34022319) but wonder if these trends are seen clinically.
