Novel Pretreatment Autoantibodies Correlate with Enfortumab Vedotin-Related Dermatologic Events in Patients with Advanced Urothelial Cancer.
Article in Cancer research communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Enfortumab vedotin (EV) plus pembrolizumab (P) is the first-line treatment for patients with advanced urothelial cancer (aUC). No biomarker for EV toxicity or response has been prospectively validated. EV-related dermatologic events (EVDE) are common and correlate with improved outcomes in retrospective studies. Immune checkpoint inhibitor-related toxicity also correlates with improved outcomes, and the presence of autoantibodies correlates with improved responses. We hypothesized that EV unmasks preexisting subclinical autoimmune responses leading to EVDEs in the setting of EV or EV/P. Our goal was to determine whether novel autoantibodies, if detected, correlate with EVDEs. We screened for novel autoantibodies using an immunoprecipitation-based approach in a pilot retrospective cohort (A) and a prospective longitudinal cohort (B) of patients with aUC who were treated with EV or EV/P and experienced EVDEs. Incidence of EVDEs, radiographic response, and progression-free and overall survival were compared between patients with and without autoantibodies. Two of six cohort A patients had pretreatment autoantibodies [Rho-associated coiled-coil containing protein kinase 2 (one patient) and target of Myb1-like 1 membrane trafficking protein (one patient)]. Pretreatment autoantibodies were also identified in 6/23 cohort B patients [mitochondrial complex 3 - M2 antigen (four patients), NMD3 ribosome export adapter (two patients), and carnitine palmitoyltransferase (one patient)]. All six (100%) cohort B antibody-positive patients developed EVDEs during treatment. To our knowledge, this is the first study correlating EVDEs with novel pretreatment autoantibodies in patients with mUC. Further studies are needed to confirm that they are biomarkers of EV-related skin toxicity and/or response. SIGNIFICANCE: EV is approved alone and with pembrolizumab (EV/P) for aUC. EV-related dermatologic events (EVDEs) have been correlated with improved outcomes. We identified novel pre- and on-treatment autoantibodies in sera of patients with mUC treated with EV or EV/P which correlated with EVDEs.
