Efficacy and safety of etrasimod, a sphingosine 1‐phosphate receptor modulator, in adults with moderate‐to‐severe atopic dermatitis (<scp>ADVISE</scp>)
Bibliographic record
Abstract
BACKGROUND: modulator in development for immune-mediated inflammatory disorders. Efficacy and safety of orally administered S1P receptor modulation in atopic dermatitis (AD) have not yet been examined. OBJECTIVE: To assess the efficacy and safety of etrasimod monotherapy in adults with moderate-to-severe AD. METHODS: In this phase 2, randomized, double-blind, placebo-controlled trial, participants (≥18 years) with moderate-to-severe AD defined as baseline validated Investigator's Global Assessment (vIGA-AD) score ≥ 3, Eczema Area and Severity Index (EASI) score ≥ 16, and body surface area involvement ≥10% were randomized 1:1:1 to once-daily oral etrasimod 1 mg, 2 mg or placebo for 12 weeks. The primary outcome was percent change in EASI score from baseline at week 12, assessed in the Full Analysis Set (all randomized participants). Key secondary outcomes were achievement of a vIGA-AD score of 0 or 1 with a ≥2-point improvement from baseline and EASI-75 response at Week 12. Safety was assessed during the double-blind period. RESULTS: One hundred and forty participants were randomized to etrasimod 2 mg (n = 47), 1 mg (n = 47) or placebo (n = 46). At Week 12, percent change in EASI score was -57.2% in the etrasimod 2-mg group versus -48.4% in the placebo group (p = 0.18). A significantly greater proportion of participants receiving etrasimod 2 mg achieved vIGA-AD scores of 0 or 1 with a ≥2-point improvement at Week 12 versus placebo (29.8% vs. 13.0%; p = 0.045); however, EASI-75 response was not statistically significant versus placebo. Treatment-emergent adverse events (AEs) occurred in 59.6%, 40.4% and 47.8% of participants receiving etrasimod 2 mg, 1 mg and placebo, respectively. There were no serious AEs or deaths. CONCLUSIONS: The primary outcome was not met, although efficacy was observed for etrasimod 2 mg on several clinician- and patient-assessed measures, and both 1- and 2-mg doses were well tolerated, warranting further clinical investigation in AD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
