Importance Lichen planus is a chronic, highly pruritic, inflammatory disease that affects the skin and other tissues. Objective To evaluate the efficacy and safety of ruxolitinib, 1.5%, cream in patients with cutaneous lichen planus. Design, Setting, and Participants This phase 2, 16-week, randomized, double-blind, vehicle-controlled trial with a 16-week open-label extension was conducted from November 2022 to February 2024. Patients were enrolled from 19 sites in the US and Canada. The trial included adults with predominantly cutaneous lichen planus, an Investigator’s Global Assessment (IGA) score of 3 or 4, an Itch Numerical Rating Scale score of 4 or greater, and an affected body surface area of 20% or less were enrolled. Data were analyzed from February to August 2024. Interventions Patients were randomized 1:1 to ruxolitinib, 1.5%, twice daily cream or vehicle cream for 16 weeks, after which eligible patients applied ruxolitinib cream twice daily as needed in a 16-week, open-label extension. Main Outcomes and Measures The primary end point was IGA treatment success (IGA score of 0 or 1 [clear/almost clear skin] with a ≥2-grade improvement from baseline) at week 16. Results Among 64 randomized patients, 46 (72%) were female, 18 (28%) were male, 18 (28%) were African American/Black, 4 (6%) were Asian, 40 (63%) were White, and the median (range) age was 57.0 (18-78) years. Significantly more patients who applied ruxolitinib, 1.5%, cream vs vehicle achieved IGA treatment success (50.0% [95% CI, 31.9%-68.1%] vs 21.9% [95% CI, 9.3%-40.0%], respectively; response rate difference, 29.4% [95% CI, 7.6%-51.3%]; P = .01; primary end point) at week 16, with further improvement to week 32. Similar results were observed in the proportion of patients who achieved a 4 or greater–point improvement from baseline in Itch Numerical Rating Scale score (week 16, 48.4% [95% CI, 30.2%-66.9%] vs 16.1% [95% CI, 5.5%-33.7%]; response rate difference, 33.5%; 95% CI, 12.2%-54.9%; P = .004; secondary end point). No serious treatment-emergent adverse events or discontinuations due to an adverse event were observed with ruxolitinib cream. Conclusions and Relevance The results of this randomized clinical trial suggest that ruxolitinib cream significantly reduced lesions and itch in patients with lichen planus. Therefore, ruxolitinib cream represents a potential treatment option for patients with cutaneous lichen planus. Trial Registration ClinicalTrials.gov Identifier: NCT05593432

Abstract Background Persistent organ failure (POF) is the strongest determinant of mortality in acute pancreatitis (AP). There is a paucity of data regarding the impact of different POF attributes on mortality and the role of different characteristics of systemic inflammatory response syndrome (SIRS) in the risk of developing POF. Objective We aimed to assess the association of POF dynamic features with mortality and SIRS characteristics with POF. Methods We studied 1544 AP subjects prospectively enrolled at 22 international centers (APPRENTICE consortium). First, we estimated the association of onset, duration, and maximal score of SIRS with POF. Then, we evaluated the risk of mortality based on POF onset, duration, number, type, and sequence of organs affected. Analyses were adjusted for potential confounders. Results 58% had SIRS, 11% developed POF, and 2.5% died. Early SIRS, persistent SIRS, and maximal SIRS score ≥ 3 were independently associated with higher risk of POF ( p < 0.05). Mortality risk in POF was higher with two (33%, odds ratio [OR] = 10.8, 3.3–34.9) and three (48%, OR = 20.2, 5.9–68.6) organs failing, in comparison to single POF (4%). In subjects with multiple POF, mortality was higher when the cardiovascular and respiratory systems failed first or concurrently as compared to when the renal system failed first or concurrently with other organ ( p < 0.05). In multivariate regression model, the number and sequence of organs affected in POF were associated with mortality ( p < 0.05). Onset and duration of POF had no impact mortality. Conclusion In AP patients with POF, the risk of mortality is influenced by the number, type, and sequence of organs affected. These results are useful for future revisions of AP severity classification systems.

AbstractBackground and AimThe primary aim was to validate the Pancreatitis Activity Scoring System (PASS) in a multicenter prospectively ascertained acute pancreatitis (AP) cohort. Second, we investigated the association of early PASS trajectories with disease severity and length of hospital stay (LOS).MethodsData were prospectively collected through the APPRENTICE consortium (2015–2018). AP severity was categorized based on revised Atlanta classification. Delta PASS (ΔPASS) was calculated by subtracting activity score from baseline value. PASS trajectories were compared between severity subsets. Subsequently, the cohort was subdivided into three LOS subgroups as short (S‐LOS): 2–3 days; intermediate (I‐LOS): 3–7 days; and long (L‐LOS): ≥7 days. The generalized estimating equations model was implemented to compare PASS trajectories.ResultsThere were 434 subjects analyzed including 322 (74%) mild, 86 (20%) moderately severe, and 26 (6%) severe AP. Severe AP subjects had the highest activity levels and the slowest rate of decline in activity (P = 0.039). Focusing on mild AP, L‐LOS subjects (34%) had 28 points per day slower decline; whereas, S‐LOS group (13%) showed 34 points per day sharper decrease compared with I‐LOS (53%; P < 0.001). We noticed an outlier subset with a median admission‐PASS of 466 compared with 140 in the rest. Morphine equivalent dose constituted 80% of the total PASS in the outliers (median morphine equivalent dose score = 392), compared with only 25% in normal‐range subjects (score = 33, P value < 0.001).ConclusionsThis study highlighted that PASS can quantify AP activity. Significant differences in PASS trajectories were found both in revised Atlanta classification severity and LOS groups, which can be harnessed in AP monitoring/management (ClincialTrials.gov number, NCT03075618).
