TL;DR

It is suggested that treatment-emergent skin toxic effects may serve as an early clinical marker of treatment benefit in patients receiving first-line enfortumab vedotin plus pembrolizumab and warrant prospective validation.

Abstract

Key Points Question Among patients with locally advanced or metastatic urothelial carcinoma receiving first-line enfortumab vedotin plus pembrolizumab, is treatment-emergent skin toxic effects associated with improved clinical outcomes? Findings In this cohort study of 185 patients, treatment-emergent skin toxic effects occurred in more than half of patients (53%) and was associated with longer overall survival in time-dependent analyses accounting for immortal-time bias. Meaning These findings suggest that treatment-emergent skin toxic effects may serve as an early clinical marker of treatment benefit in patients receiving first-line enfortumab vedotin plus pembrolizumab and warrant prospective validation.

Toxicity attribution during enfortumab vedotin plus pembrolizumab therapy in urothelial carcinoma: a practical framework

Abstract Enfortumab vedotin (EV), pembrolizumab, and EV plus pembrolizumab (EV/P) have rapidly reshaped the treatment landscape of advanced urothelial carcinoma, but toxicity increasingly determines treatment delivery, treatment continuity, and real-world benefit. As EV/P moves into broader clinical use, clinicians mus...
