Pan-Asian subgroup analysis of EV-302/KEYNOTE-A39: a phase 3 study to evaluate enfortumab vedotin and pembrolizumab in patients with untreated advanced urothelial carcinoma.
Trial report in International journal of clinical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04223856 (An Open-label, Randomized, Controlled Phase 3 Study of Enfortumab Vedotin in Combination With Pembrolizumab Versus Chemotherapy Alone in Previously Untreated Locally Advanced or Metastatic Urothelial Cancer), which is not on this map.

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.

Abstract
backgroundIn the phase 3 EV-302 study, enfortumab vedotin-pembrolizumab (EV + P) significantly prolonged overall survival (OS) and progression-free survival (PFS) versus chemotherapy in patients with untreated locally advanced/metastatic urothelial carcinoma (la/mUC). We present a post hoc analysis in a pan-Asian population.
methodsPatients from China, Japan, Singapore, South Korea, Taiwan, and Thailand received 3-week cycles of EV (1.25 mg/kg; intravenously; Days 1 and 8) plus P (200 mg; intravenously; Day 1) or chemotherapy (gemcitabine [Days 1 and 8] plus cisplatin/carboplatin [Day 1]). Primary endpoints were PFS and OS. Secondary endpoints included objective response rate (ORR) and safety.
resultsOverall, 176 patients were included (EV + P, n = 94; chemotherapy, n = 82). Median follow-up was 28.9 months for EV + P recipients and 26.6 months for chemotherapy recipients. EV + P prolonged PFS and OS versus chemotherapy, reducing the risk of disease progression or death by 63% (hazard ratio [HR], 0.37; 95% confidence interval [CI], 0.24-0.57) and death by 67% (HR, 0.33; [95% CI, 0.20-0.54]), respectively. Confirmed ORR was 72.2% versus 35.0%. Grade ≥ 3 treatment-related adverse events occurred in 66.0% of EV + P recipients and 68.4% of chemotherapy recipients. Most commonly maculopapular rash (11.7%) and hyperglycemia (10.6%) for EV + P and neutropenia (25.0%), anemia (19.7%), and neutrophil count decreased (18.4%) for chemotherapy.
conclusionEV + P demonstrated a clinically meaningful survival benefit in Asian patients with untreated la/mUC, with no new safety signals observed, consistent with the global EV-302 study. Results support guideline recommendations for EV + P as preferred first-line therapy in la/mUC. CLINICAL
