What this trial studies

The ARON-2 study is a multicentric international retrospective analysis focusing on patients with urothelial carcinoma who have been treated with pembrolizumab or enfortumab vedotin. It aims to evaluate the efficacy of these treatments in patients who are either platinum-unfit or have progressed after platinum-based chemotherapy. The study will utilize artificial intelligence technology, specifically an Artificial Neural Network, to analyze real-world experiences and outcomes from these therapies. Data will be collected from patients treated between specified timeframes to assess treatment effectiveness.
