Verteporfin attenuates NLRP3 inflammasome activation to alleviate gout arthritis flares.
Article in Journal of inflammation (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundGout arthritis (GA) is an inflammatory disorder characterized by the deposition of monosodium urate (MSU) crystals within synovial joints due to increased urate concentrations in the body. The NLRP3 inflammasome drives a majority of the inflammatory response to MSU crystals; therefore, we hypothesize pharmaceutical agents that attenuate NLRP3 inflammasome activation could be used to treat GA flares.
resultsWe screened a drug library containing 875 FDA-approved drugs and identified five drugs that reduced NLRP3 inflammasome activation without causing cytotoxic effects in bone marrow-derived macrophages (BMDM). The best performing and therefore leading candidate, verteporfin, used to treat macular degeneration and other eye disorders, reduced Nlrp3- and Caspase-1-dependent IL-1β and IL-18 secretion by BMDM. Additionally, verteporfin-treated mice showed a marked reduction in paw swelling and pro-inflammatory cytokine/chemokine induction, including inflammasome markers (IL-1β and IL-18), in a MSU-induced mouse model of GA flares.
conclusionCollectively, these data suggest verteporfin is a NLRP3 inflammasome inhibitor that could be repurposed as a treatment for GA.
