Abstract
Abstract Background Oral lichen planus (OLP) is a chronic inflammatory disorder of the oral mucosa. Currently there is no approved treatment for OLP. We report on the efficacy and safety of a novel mucoadhesive clobetasol patch (Rivelin ® ‐CLO) for the treatment of OLP. Methods Patients with confirmed OLP and measurable symptomatic ulcer(s) participated in a randomized, double‐blind, placebo‐controlled, multicenter clinical trial testing a novel mucoadhesive clobetasol patch (Rivelin ® ‐CLO) in OLP across Europe, Canada, and the United States. Patients were randomized to placebo (nonmedicated), 1, 5, 20 µg Clobetasol/patch, twice daily, for 4 weeks. The primary endpoint was change in total ulcer area compared to baseline. Secondary endpoints included improvement from baseline in pain, disease activity, and quality of life. Results Data were analyzed and expressed as mean [SD]. One hundred thirty‐eight patients were included in the study; 99 females and 39 males, mean age was 61.1 [11.6] years. Statistical analyses revealed that treatment with 20‐μg Rivelin ® ‐CLO patches demonstrated significant improvement with ulcer area ( p = 0.047), symptom severity ( p = 0.001), disease activity ( p = 0.022), pain ( p = 0.012), and quality of life ( p = 0.003) as compared with placebo. Improvement in OLP symptoms from beginning to the end of the study was reported as very much better (best rating) in the 20‐µg group (25/32) patients compared to the placebo group (11/30), ( p = 0.012). Adverse events were mild/moderate. Candidiasis incidence was low (2%). Conclusions Rivelin ® ‐CLO patches were superior to placebo demonstrating statistically significant, clinically relevant efficacy in objective and subjective improvement and, with a favorable safety profile.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
