Real-World Outcomes of First-Line Treatment of Metastatic or Locally Advanced Upper Tract Urothelial Carcinoma With Enfortumab Vedotin Plus Pembrolizumab : A French Multicenter Retrospective Observational Study
Condition(s) studied
Investigational drug(s) / intervention(s)
enfortumab vedotin plus pembrolizumab in first line setting for advanced upper tract urothelial carcinoma: enfortumab vedotin plus pembrolizumab for advanced upper tract urothelial carcinoma, from september 2024 (time of the French ATU) to december 2025 (time of inclusion minus 6 months follow up)
Study summary
The combination of Enfortumab Vedotin and Pembrolizumab has substantially improved outcomes for patients with advanced urothelial carcinoma and has emerged as a new standard of care in the first-line setting. However, data specifically regarding its use in patients with Upper Tract Urothelial Carcinoma (UTUC) remain limited.
This multicenter retrospective observational study aims to evaluate the real-world efficacy and safety of Enfortumab Vedotin plus Pembrolizumab as first-line treatment in patients with metastatic or locally advanced Upper Tract Urothelial Carcinoma (UTUC). The primary outcome will include objective response rate (ORR). Secondary outcomes will include progression-free survival (PFS), overall survival (OS), time to treatment response (TTR) and treatment-related toxicity.
In addition, the study will explore potential associations between clinical outcomes and selected molecular and immunohistochemical biomarkers, including Nectin-4 expression, microsatellite instability (MSI) status, and programmed death-ligand 1 (PD-L1) expression. These exploratory analyses may help identify predictive factors of response and contribute to a better understanding of treatment outcomes in this specific patient population.
