UGN-102 for Recurrent Low-Grade Intermediate-Risk Nonmuscle-Invasive Bladder Cancer: 24-Month Duration of Response Results From the Phase 3 ENVISION Trial.
Trial report in The Journal of urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05243550 (A Phase 3, Single-Arm, Multicenter Study to Evaluate the Efficacy and Safety of UGN-102 as Primary Chemoablative Therapy in Patients With Low-Grade), which is not on this map. Not yet cited in PubMed.
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.

Abstract
purposeWe report the duration of response to UGN-102 treatment in patients with recurrent low-grade intermediate-risk nonmuscle-invasive bladder cancer (LG-IR-NMIBC) 24 months after achieving complete response (CR). MATERIALS AND
methodsENVISION is an ongoing, multinational, single-arm, phase 3 study in patients with biopsy-proven recurrent LG-IR-NMIBC. Patients received 6 once-weekly intravesical instillations of UGN-102. Patients underwent cystoscopy, urine cytology testing, and for-cause biopsy to determine bladder cancer presence at 3 months. Duration of response (from CR at 3 months to disease recurrence, progression, or death from any cause) at 24 months was estimated using the Kaplan-Meier method.
resultsA total of 240 patients were enrolled and received ≥ 1 dose of UGN-102. Most patients were White (98%), male (61%), and aged ≥ 65 years (68%). At 3 months, 191 patients (80%; 95% CI: 74-85) achieved CR. Among these responders, the probability of remaining event-free 24 months after CR was 72% (95% CI: 64-79; Kaplan-Meier estimate). Among patients with CR at 3 months (n = 191), 36 developed low-grade disease recurrence. A treatment-emergent adverse event that occurred in ≥ 10% of enrolled patients (N = 240) was dysuria.
conclusionsPatients who achieved CR after UGN-102 treatment had a high probability of remaining event-free 24 months later. These data indicate that UGN-102 is a novel, nonsurgical treatment that provides a durable CR for patients with recurrent LG-IR-NMIBC. Study limitations included the single-arm design and the limited racial diversity of the patients.
