Background: Atopic dermatitis (AD), a relapsing, inflammatory skin disease, is associated with pruritus that can negatively affect patients' quality of life. Understanding the burden of AD is critical for informing and tailoring treatment and disease management to improve patient outcomes. This study characterized global treatment patterns and the clinical, psychosocial and economic burden of moderate‐to‐severe AD. Methods: MEASURE‐AD was a cross‐sectional 28‐country study in patients with physician‐confirmed moderate‐to‐severe AD who were either receiving or eligible for systemic therapy for AD. Patients ≥12 years were enrolled between December 2019 and December 2020 while attending routine office or clinic visit. Primary outcomes included Worst Pruritus Numeric Rating Scale (WP‐NRS; range: 0–10) and Dermatology Life Quality Index (DLQI; range: 0–30) and Children's DLQI (CDLQI; range: 0–30). Secondary outcomes included physician‐ and patient‐reported clinical, psychosocial and economic burden. Results: Of the 1591 patients enrolled, 1558 (1434 adults and 124 adolescents) fulfilled all patient selection criteria and were included in this analysis. Almost all patients (98.4%) in the total population were using AD medications and more than half (56%) were receiving systemic medication (15% systemic monotherapy). The most used systemic therapies were dupilumab (56.3%), systemic glucocorticoids (18.1%) and methotrexate (16.2%). Mean WP‐NRS was 5.3 in the total population, and most patients (≥55%) reported moderate‐to‐severe pruritus (WP‐NRS ≥4). Mean DLQI was 10.8 and mean CDLQI was 9.6. Secondary endpoints demonstrated substantial clinical, psychosocial, and economic burden of disease. Subgroup analysis demonstrated that patients receiving systemic therapy had lower disease burden than those not taking systemic medications. Conclusions: While systemic therapy lowers overall disease burden, patients with moderate‐to‐severe AD continue to have substantial multidimensional disease burden and uncontrolled disease. Overall, there is a need for effective disease management, including effective treatments that improve patients' psychosocial outcomes and reduce the economic burden of AD. [ABSTRACT FROM AUTHOR]

Psoriasis is a common chronic immune-mediated disease with many comorbidities and impacts on quality of life. Among the treatments for psoriasis, phosphodiesterase-4 (PDE4) inhibitors are emerging with expanding options. PDE4 inhibitors play a pivotal role in the inflammatory cascade by degrading cyclic adenosine monophosphate (cAMP), contributing to pro-inflammatory mediator production. Apremilast, an oral PDE4 inhibitor, is approved for psoriasis. While effective, its adverse effects can limit its utility. Roflumilast, a topical PDE4 inhibitor, was also recently approved for psoriasis and shows promise in clinical trials. Crisaborole, a PDE4 inhibitor approved for atopic dermatitis, has also been studied in psoriasis. This review summarizes evidence from randomized clinical trials regarding the efficacy and safety of PDE4 inhibitors in psoriasis treatment. By highlighting their potential benefits and limitations, this review provides valuable insights for clinicians and researchers aiming to optimize psoriasis management. [ABSTRACT FROM AUTHOR]

Background: Abrocitinib efficacy by comorbidity status in patients with moderate‐to‐severe atopic dermatitis (AD) has not been previously assessed. This post hoc analysis evaluated the efficacy and safety of abrocitinib in patients with AD and allergic comorbidities. Methods: Data were pooled from patients who received abrocitinib 200 mg, 100 mg, or placebo in phase 2b (NCT02780167) and phase 3 (NCT03349060, NCT03575871) monotherapy trials. Patients with and without allergic comorbidities (allergic asthma, rhinitis, conjunctivitis, or food allergy) were evaluated for Investigator's Global Assessment (IGA) response (clear [0] or almost clear [1]), ≥75% improvement in the Eczema Area and Severity Index (EASI‐75), ≥4‐point improvement in Peak Pruritus Numerical Rating Scale (PP‐NRS4), and Dermatology Life Quality Index (DLQI) response (<2 with baseline score ≥2). Other outcomes were Patient‐Oriented Eczema Measure (POEM), SCORing Atopic Dermatitis (SCORAD), Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD), and treatment‐emergent adverse events (TEAEs). Results: Of 942 patients, 498 (53%) reported at least one allergic comorbidity (asthma only, 33%; conjunctivitis only or rhinitis only or both, 17%; food allergies only, 15%; >1 allergic comorbidity, 34%). Regardless of comorbidity status, from Week 2 to Week 12, higher percentages of patients treated with either abrocitinib dose achieved IGA 0/1, EASI‐75, PP‐NRS4, or DLQI 0/1 versus placebo‐treated patients. Changes from baseline in POEM, SCORAD, and PSAAD were greater with abrocitinib than with placebo in patients with and without allergic comorbidities. Most TEAEs were mild or moderate. Conclusions: Efficacy and safety data support abrocitinib use to manage AD in patients with or without allergic comorbidities. [ABSTRACT FROM AUTHOR]

Introduction/Background Vitiligo is a chronic autoimmune disease characterized by melanocyte destruction, leading to skin depigmentation. Limited data are available regarding the efficacy of long-term topical vitiligo treatment. In 2 randomized, double-blinded, vehicle-controlled phase 3 studies in adults and adolescents (aged ≥12 y) with nonsegmental vitiligo (TRuE-V1 [NCT04052425]; TRuE-V2 [NCT04057573]), ruxolitinib cream application resulted in statistically superior improvements in repigmentation versus vehicle in the primary and all key secondary endpoints at Week 24 and was well tolerated. In the open-label period of TRuE-V1/TRuE-V2 (Weeks 24-52) and the TRuE-V long-term extension (LTE; Weeks 52-104) study (NCT04530344), further improvements in facial and body repigmentation (as assessed by Vitiligo Area Scoring Index [VASI] responses) were observed through Week 104 among patients who continued to apply ruxolitinib cream. Objectives: In this pooled analysis, we evaluated shifts in facial and total body VASI (F-VASI/T-VASI) responses among patients with vitiligo who had limited or no repigmentation at Week 24 and who continued to apply ruxolitinib cream for an additional 80 weeks. Methods: In TRuE-V1/TRuE-V2, patients were randomized 2:1 to apply twice-daily 1.5% ruxolitinib cream or vehicle for 24 weeks, after which all patients could apply 1.5% ruxolitinib cream through Week 52. Patients who completed TRuE-V1/TRuE-V2 were eligible to enroll in the TRuE-V LTE. Patients who did not achieve ≥90% improvement in F-VASI at Week 52 continued to apply open-label 1.5% ruxolitinib cream until Week 104. Patients initially randomized to apply ruxolitinib cream who had <25% improvement from baseline in F-VASI or T-VASI at Week 24 and had non-missing VASI assessments at the evaluated time points were included in this analysis. Shifts in F-VASI and T-VASI were assessed among patients with no facial/body repigmentation or worsening depigmentation (≤0% improvement in F-VASI/T-VASI) and patients with limited facial/body repigmentation (>0%- <25% improvement in F-VASI/T-VASI) at Week 24. Results: Among patients with no facial repigmentation at Week 24, improvements in F-VASI at Weeks 52 and 104 were observed in 77.8% (49/63) and 97.1% (34/35) of patients, respectively. Among patients with limited facial repigmentation at Week 24, F-VASI improvements at Weeks 52 and 104 were observed in 64.0% (32/50) and 83.3% (30/36) of patients, respectively. Across both groups, 54.9% (39/71) of patients achieved =75% improvement from baseline in F-VASI (F-VASI75) at Week 104. Among those with no body repigmentation at Week 24, T-VASI improvements at Weeks 52 and 104 were observed in 79.6% (39/49) and 93.3% (28/30) of patients, respectively. For those with limited body repigmentation at Week 24, T-VASI improvements at Weeks 52 and 104 were observed in 64.5% (80/124) and 81.6% (62/76) of patients, respectively. Across both groups who had <25% improvement in total body repigmentation at Week 24, 50.0% (53/106) of patients achieved ≥50% improvement in T-VASI (T-VASI50) at Week 104. Conclusions: In the TRuE-V studies, ruxolitinib cream application for an additional 80 weeks resulted in improved repigmentation among patients with nonsegmental vitiligo who had limited or no repigmentation at Week 24. These 2-year TRuE-V results highlight the importance of prolonged treatment in patients with vitiligo, even when minimal or no repigmentation is achieved after 6 months of treatment.
