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

France50 participantsStarted 2026-07-01

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
