Incidence and outcomes of FGFR inhibitor-associated retinopathy of patients treated with oral erdafitinib across the clinical trial program.
Article in The oncologist, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundFibroblast growth factor receptors inhibitors (FGFRi) are approved treatments for various malignancies. FGFRi-associated retinopathy is a class effect of FGFRi, including erdafitinib, pemigatinib, infigratinib, and rogaratinib. PATIENTS AND
methodsWe summarized FGFRi-associated retinopathy with erdafitinib across 5 clinical studies in patients with metastatic urothelial cancer (mUC pooled studies) and one study in patients with advanced solid tumors (RAGNAR). We also present changes in visual acuity, retinal pigment epithelial elevation, and subretinal fluid in RAGNAR.
resultsOne hundred and three (21.5%) of 479 patients in the mUC pooled studies and 43/314 (13.7%) patients in RAGNAR experienced FGFRi-associated retinopathy. Most FGFRi-associated retinopathy were Grade 1/2 events. Grade 3 FGFRi-associated retinopathy were infrequent (mUC pooled studies, 11/479 [2.3%]; RAGNAR, 3/314 [1.0%]). No Grade 4 events occurred. Most FGFRi-associated retinopathy events (mUC pooled studies, 81/103 [78.6%]; RAGNAR, 30/43 [70.0%]) occurred within 90 days of treatment initiation and were managed with erdafitinib dose interruption (mUC pooled studies, 41/479 [8.6%]; RAGNAR, 23/314 [7.3%]) or reduction (mUC pooled studies, 58/479 [12.1%]; RAGNAR, 21/314 [6.7%]); few required treatment discontinuation (mUC pooled studies, 14/479 [2.9%]; RAGNAR, 3/314 [1.0%]). By the data cutoff, 63.1% (65/103) patients in the mUC pooled studies and 65.1% (28/43) patients in RAGNAR had their FGFRi-associated retinopathy events resolve. Most unresolved FGFRi-associated retinopathy events were persistent Grade 1 events. In RAGNAR, 92.0% of patients had their visual acuity return to baseline and 78.5% of patients had their retinal pigment epithelial elevation resolve.
conclusionsFGFRi-associated retinopathy with erdafitinib can be managed with dose reductions, interruptions, or discontinuations. Proactive collaboration between oncologists and ophthalmologists is required to ensure that erdafitinib delivers clinical benefit to patients while managing their potential adverse symptoms of FGFRi-associated retinopathy.
