Efficacy and safety of etrasimod in Japanese patients with ulcerative colitis: results from a phase 2 dose-ranging study.
Article in Intestinal research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05061446 (A Phase 2, Randomized, Double-Blind, Placebo-Controlled, 12-Week Dose-Ranging Study to Assess the Efficacy and Safety of Etrasimod in Japanese Participants With Moderately to Severely Active Ulcerative Colitis), 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.

Abstract
BACKGROUND/
aimsEtrasimod is an oral, once-daily, selective sphingosine 1-phosphate1,4,5 receptor modulator for the treatment of moderately to severely active ulcerative colitis (UC). However, its efficacy, safety, and the appropriate dosage have not been extensively investigated in the Japanese population.
methodsThis phase 2, multicenter, randomized, double-blind, placebo-controlled dose-ranging, 12-week trial was carried out among Japanese patients with moderately to severely active UC. Patients were randomized 1:1:1 to receive etrasimod 1 mg once daily (QD), etrasimod 2 mg QD, or placebo. The primary efficacy endpoint was the proportion of patients achieving clinical remission at week 12. Secondary efficacy endpoints and treatmentemergent adverse events (TEAEs) were also investigated. Efficacy endpoints were presented as proportions of patients achieving each outcome.
resultsOverall, 17, 19, and 18 patients received etrasimod 1 mg QD, etrasimod 2 mg QD, and placebo, respectively. One patient receiving etrasimod 1 mg (6.7%), 5 patients receiving etrasimod 2 mg (26.3%), and no patients receiving placebo (0%) achieved clinical remission. More patients receiving etrasimod versus placebo achieved secondary endpoints, except endoscopic normalization, at week 12. TEAEs were experienced by 9 patients receiving etrasimod 1 mg (52.9%), 13 patients receiving etrasimod 2 mg (68.4%), and 10 patients receiving placebo (55.6%). None of the TEAEs were serious and none experienced by patients receiving etrasimod led to treatment discontinuation.
conclusionsOverall, etrasimod 2 mg QD for up to 12 weeks appeared efficacious and safe in these Japanese patients with moderately to severely active UC. All TEAEs were mild to moderate in severity. (ClinicalTrials.gov: NCT05061446).
