Efficacy and safety of delgocitinib cream in adults with moderate to severe chronic hand eczema (DELTA 1 and DELTA 2): results from multicentre, randomised, controlled, double-blind, phase 3 trials.

BACKGROUND: Chronic hand eczema is a fluctuating, inflammatory, pruritic, often painful disease of hands and wrists that strongly impacts quality of life and occupational capabilities of patients. The aim of phase 3 DELTA 1 and DELTA 2 was to assess the efficacy and safety of twice-daily applications of the topical pan-Janus kinase inhibitor delgocitinib cream 20 mg/g versus cream vehicle in adults with moderate to severe chronic hand eczema. METHODS: Both trials were randomised, double-blinded, and vehicle-controlled, with DELTA 1 being conducted at 53 trial centres in Canada, France, Germany, Italy, Poland, and the UK and DELTA 2 at 50 trial centres in Belgium, Canada, Denmark, Germany, the Netherlands, Poland, and Spain. Adults (aged ≥18 years) with moderate to severe chronic hand eczema were randomly assigned 2:1 to twice-daily delgocitinib cream 20 mg/g or cream vehicle for 16 weeks. The primary endpoint was Investigator's Global Assessment for Chronic Hand Eczema (IGA-CHE) treatment success at week 16, defined as IGA-CHE score of 0 (clear) or 1 (almost clear, defined as only barely perceptible erythema). Efficacy and safety were assessed in all patients who were exposed to trial treatment. These trials are registered with ClinicalTrials.gov, NCT04871711 and NCT04872101. FINDINGS: Between May 10, 2021, and Oct 31, 2022, 487 patients (181 male and 306 female) were enrolled in DELTA 1; between May 25, 2021, and Jan 6, 2023, 473 patients (161 male and 312 female) were enrolled in DELTA 2. 325 patients in DELTA 1 and 314 in DELTA 2 were assigned to delgocitinib cream; 162 patients in DELTA 1 and 159 in DELTA 2 were assigned to cream vehicle. At week 16, a greater proportion of delgocitinib-treated patients versus cream vehicle patients had IGA-CHE treatment success (64 [20%] of 325 vs 16 [10%] of 162 in DELTA 1 and 91 [29%] of 313 vs 11 [7%] of 159 in DELTA 2; both trials p≤0·0055). The proportion of patients who reported adverse events was similar with delgocitinib (147 [45%] of 325 in DELTA 1 and 143 [46%] of 313 in DELTA 2) and the cream vehicle (82 [51%] of 162 in DELTA 1 and 71 [45%] of 159 in DELTA 2). Most frequent adverse events occurring in at least 2% of patients were similar in both treatment groups and included COVID-19 and nasopharyngitis. INTERPRETATION: Overall, delgocitinib cream showed superior efficacy versus cream vehicle and was well tolerated over 16 weeks. These results support the clinical benefit of delgocitinib cream as a potential treatment option for patients with moderate to severe chronic hand eczema, who are unable to adequately control their disease with basic skin care practices and topical corticosteroids.

Bimekizumab versus Secukinumab in Plaque Psoriasis.

BACKGROUND: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits both interleukin-17A and interleukin-17F. The efficacy and safety of bimekizumab as compared with secukinumab, which selectively inhibits interleukin-17A alone, in patients with moderate-to-severe plaque psoriasis have not been extensively examined. METHODS: In this phase 3b trial, we randomly assigned patients with moderate-to-severe plaque psoriasis, in a 1:1 ratio, to receive bimekizumab subcutaneously at a dose of 320 mg every 4 weeks or secukinumab subcutaneously at a dose of 300 mg weekly to week 4, followed by every 4 weeks to week 48. At week 16, patients receiving bimekizumab underwent rerandomization, in a 1:2 ratio, to receive maintenance dosing every 4 weeks or every 8 weeks to week 48. The primary end point was 100% reduction from baseline in the Psoriasis Area and Severity Index (PASI) score at week 16. The primary analysis was first tested for the noninferiority of bimekizumab to secukinumab at a margin of -10 percentage points and then tested for superiority. RESULTS: A total of 1005 patients were screened and 743 were enrolled; 373 patients were assigned to receive bimekizumab and 370 to receive secukinumab. At week 16, a total of 230 patients (61.7%) in the bimekizumab group and 181 (48.9%) in the secukinumab group had a 100% reduction from baseline in the PASI score (PASI 100) (adjusted risk difference, 12.7 percentage points; 95% confidence interval [CI], 5.8 to 19.6); bimekizumab was shown to be noninferior and superior to secukinumab (P<0.001 for noninferiority and superiority). At week 48, a total of 250 patients (67.0%) treated with bimekizumab had a PASI 100 response, as compared with 171 patients (46.2%) treated with secukinumab (adjusted risk difference, 20.9 percentage points; 95% CI, 14.1 to 27.7; P<0.001). At the week 4 time point, 265 patients (71.0%) in the bimekizumab group had 75% or greater reduction from baseline in the PASI score, as compared with 175 patients (47.3%) in the secukinumab group (adjusted risk difference, 23.7; 95% CI, 17.0 to 30.4; P<0.001). Oral candidiasis occurred more often with bimekizumab (72 patients, 19.3%) than with secukinumab (11 patients, 3.0%). CONCLUSIONS: In patients with moderate-to-severe psoriasis, treatment with bimekizumab resulted in greater skin clearance than treatment with secukinumab over 16 and 48 weeks but was associated with oral candidiasis (predominantly mild or moderate as recorded by the investigator). Longer and larger trials are required to determine the comparative effect and risks of interleukin-17 inhibitors in psoriasis.

Efficacy and safety of abrocitinib in patients with moderate-to-severe atopic dermatitis and comorbid allergies.

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.

Orismilast in moderate-to-severe psoriasis: Efficacy and safety from a 16-week, randomized, double-blinded, placebo-controlled, dose-finding, and phase 2b trial (IASOS).

BACKGROUND: Orismilast is a novel oral phosphodiesterase-4 (PDE4) B/D inhibitor being investigated as a potential treatment for moderate-to-severe psoriasis. OBJECTIVE: To evaluate efficacy and safety of orismilast modified-release formulation in moderate-to-severe psoriasis. METHODS: This multicenter, randomized (1:1:1:1 to 20, 30, 40 mg orismilast or placebo, twice daily), double-blinded, placebo-controlled, parallel-group, phase 2b, 16-week, dose-ranging study evaluated orismilast in adults with moderate-to-severe plaque psoriasis (NCT05190419). Efficacy end points were analyzed using multiple imputation. RESULTS: Of 202 randomized patients, baseline characteristics were balanced across arms, except greater severe disease proportions for orismilast vs placebo. Orismilast showed significant improvements in the primary end point, percentage change in Psoriasis Area and Severity Index (PASI), from baseline to week 16 (orismilast -52.6% to -63.7% and placebo, -17.3%; all P <.001). Greater proportions receiving orismilast achieved PASI75 (39.5%-49.0%; P <.05) and PASI90 (22.0%-28.3%; P <.05 for 20 and 40 mg) vs placebo (PASI75, 16.5% and PASI90, 8.3%) at week 16. Safety findings were as expected with PDE4 inhibition; dose-dependent tolerability effects observed. LIMITATIONS: Small sample size, disease severity imbalance between groups, limited duration and diversity in study population. CONCLUSION: Orismilast demonstrated greater efficacy vs placebo and a safety profile in line with PDE4 inhibition.

Long-term safety and effectiveness of roflumilast cream 0.3% in adults with chronic plaque psoriasis: A 52-week, phase 2, open-label trial.

BACKGROUND: Efficacy and/or safety profiles limit topical psoriasis treatments. OBJECTIVE: Evaluate long-term effects of once-daily roflumilast cream 0.3% in patients with psoriasis. METHODS: In this open-label phase 2 trial, adult patients (N = 332) with psoriasis who completed the phase 2b parent trial or were newly enrolled applied roflumilast once-daily for 52 weeks. Safety and effectiveness were assessed. RESULTS: Overall, 244 patients (73.5%) completed the trial; 13 patients (3.9%) discontinued due to adverse events (AEs) and 3 (0.9%) due to lack of efficacy. Twelve patients (3.6%) reported treatment-related AEs; none were serious. ≥97% of patients had no irritation. No tachyphylaxis was observed with 44.8% of the patients achieving Investigator Global Assessment (IGA) Clear or Almost Clear at Week 52. LIMITATIONS: Intertriginous-IGA and Psoriasis Area and Severity Index (PASI) were not evaluated in all patients. CONCLUSIONS: In this long-term trial, once-daily roflumilast cream was well-tolerated and efficacious up to 64 weeks in patients in the earlier trial, suggesting it is suitable for chronic treatment, including the face and intertriginous areas.

Roflumilast foam 0.3% for adolescent and adult patients with seborrheic dermatitis: A randomized, double-blinded, vehicle-controlled, phase 3 trial.

BACKGROUND: The topical phosphodiesterase 4 inhibitor roflumilast has been studied in several dermatologic conditions. OBJECTIVE: Roflumilast foam 0.3% is being investigated as a topical treatment for seborrheic dermatitis (SD). METHODS: In this phase 3, double-blinded trial, patients with SD were randomly assigned (2:1 ratio) to once-daily roflumilast foam 0.3% or vehicle foam for 8 weeks. The primary efficacy outcome was Investigator Global Assessment (IGA) Success at week 8, defined as IGA of 0 (Clear) or 1 (Almost Clear) plus ≥2-point improvement from baseline. Safety was also assessed. RESULTS: 79.5% of roflumilast-treated and 58.0% of vehicle-treated patients met the primary endpoint (P < .001); statistically significant differences in IGA Success also favored roflumilast at week 2 (roflumilast: 43.0%; vehicle: 25.7%; P < .001) and week 4 (roflumilast: 73.1%; vehicle: 47.1%; P < .001). Roflumilast was well-tolerated with a low rate of treatment-emergent adverse events. LIMITATIONS: Study limitations include the 8-week treatment period for this chronic condition. CONCLUSIONS: Once-daily roflumilast foam was superior to vehicle in leading to IGA of Clear or Almost Clear plus ≥2-point improvement from baseline at 8 weeks in patients with SD. Longer trials are needed to determine durability and safety of roflumilast foam in SD.

Combining treat-to-target principles and shared decision-making: International expert consensus-based recommendations with a novel concept for minimal disease activity criteria in atopic dermatitis.

BACKGROUND: Current treat-to-target recommendations for atopic dermatitis (AD) may not include high enough treatment targets and do not fully consider patient needs. OBJECTIVE: To develop recommendations for optimized AD management, including disease severity assessments, treatment goals and targets, and guidance for treatment escalation/modification. METHODS: An international group of expert dermatologists drafted a series of recommendations for AD management using insights from a global patient study and 87 expert dermatologists from 44 countries. Experts voted on recommendations using a modified eDelphi voting process. RESULTS: The Aiming High in Eczema/Atopic Dermatitis (AHEAD) recommendations establish a novel approach to AD management, incorporating shared decision-making and a concept for minimal disease activity (MDA). Consensus (≥70% agreement) was reached for all recommendations in 1 round of voting; strong consensus (≥90% agreement) was reached for 30/34 recommendations. In the AHEAD approach, patients select their most troublesome AD feature(s); the clinician chooses a corresponding patient-reported severity measure and objective severity measure. Treatment targets are chosen from a list of 'moderate' and 'optimal' targets, with achievement of 'optimal' targets defined as MDA. CONCLUSIONS: Patient and expert insights led to the development of AHEAD recommendations, which establish a novel approach to AD management. Patients were not involved in the eDelphi voting process used to generate consensus on each recommendation. However, patient perspectives were captured in a global, qualitative patient research study that was considered by the experts in their initial drafting of the recommendations.

Efficacy of long-term risankizumab treatment for moderate-to-severe plaque psoriasis: Subgroup analyses by baseline characteristics and psoriatic disease manifestations through 256 weeks (LIMMitless trial).

BACKGROUND: Psoriasis is an inflammatory skin disease that impacts a heterogeneous group of patients and can have multiple clinical manifestations. Risankizumab is approved for the treatment of moderate-to-severe plaque psoriasis. OBJECTIVES: To evaluate the long-term efficacy of risankizumab according to baseline patient characteristics, and for the treatment of high-impact disease manifestations (nail, scalp and palmoplantar psoriasis), through 256 weeks of continuous treatment in the phase 3 LIMMitless study. METHODS: This subgroup analysis evaluated pooled data from patients with moderate-to-severe plaque psoriasis who were randomized to risankizumab 150 mg during two double-blind, phase 3, 52-week base studies (UltIMMa-1/2; NCT02684370/NCT02684357) and were enrolled in the phase 3 LIMMitless open-label extension study (NCT03047395). Subgroup assessments included the proportion of patients who achieved ≥90%/100% improvement in Psoriasis Area and Severity Index (PASI 90/100). Among patients with nail, scalp and/or palmoplantar psoriasis in addition to skin psoriasis, assessments included changes from baseline in and resolution of these three psoriatic manifestations. RESULTS: Overall, a numerically similar proportion of patients (N = 525) achieved PASI 90/100 through Week 256, regardless of their baseline age, sex, body mass index, weight, PASI or psoriatic arthritis status. Patients with nail, scalp and/or palmoplantar psoriasis experienced substantial improvements in manifestation-specific indices (mean improvement from baseline to Week 256 of >81%, >94% and >97%, respectively); in patients with all three manifestations (N = 121), 44.6% achieved complete clearance of these manifestations at Week 256. CONCLUSIONS: Risankizumab demonstrated generally consistent efficacy through 256 weeks across patient subgroups and showed durable long-term efficacy for psoriatic disease manifestations.

Real-world clinical, psychosocial and economic burden of atopic dermatitis: Results from a multicountry study.

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.

Benefits Over Five Years of Ixekizumab Treatment in Patients With Psoriasis Involving Challenging Body Areas.

BACKGROUND: Psoriasis involving challenging body areas, such as the scalp, face, palmoplantar surfaces, or nails, can be challenging to treat and negatively affects patient outcomes. OBJECTIVE: To assess clear responses and cumulative clinical benefits over 5 years of ixekizumab treatment of moderate-to-severe plaque psoriasis in patients with and without baseline involvement of challenging body areas. METHODS: This post hoc analysis included patients treated with ixekizumab in the UNCOVER-3 trial. We assessed PASI100 responses through the week (W) 264 and cumulative clinical benefits at W264 (calculated as least-squares mean of the percentage of maximum area under the curve for PASI100 and PASI% improvement and expressed as cumulative clearance days). Statistical differences were calculated via ANCOVA. RESULTS: A total of 385 patients were analyzed: 349 with scalp involvement, 152 with facial involvement, 96 with palmoplantar involvement, and 229 with nail involvement. Proportions of patients achieving PASI100 were numerically similar between patients with and without scalp and nail involvement. More patients without facial and palmoplantar involvement achieved PASI100 at W60 (only palmoplantar), W108, W156, W204, and W264 (only palmoplantar). At W264, cumulative clinical benefits for PASI100 and PASI% improvement were high and similar in both patient groups, with and without challenging body areas. A significant difference (P=0.006) was only observed for PASI% improvement between patients with and without nail involvement. CONCLUSION: For most efficacy measures, patients treated with ixekizumab over 5 years achieved similar clear responses and cumulative clinical benefits regardless of baseline involvement of challenging body areas.

A Practical Guide to Using Biologics in Pediatric Dermatology.

Psoriasis, hidradenitis suppurativa (HS), atopic dermatitis (AD), and chronic spontaneous urticaria (CSU), are common, immune-mediated, chronic, inflammatory skin diseases that can affect the pediatric population. While there is adequate evidence supporting the use of biologics in pediatric patients, concerns regarding safety and efficacy amongst healthcare providers are not uncommon. However, new emerging evidence in this population highlights the safety of biologic therapy, making it crucial to review and establish a practical guide for their use. This article describes a methodological framework for initiating biologics in the management of pediatric psoriasis, HS, AD, and CSU, with a special focus on baseline work-up, monitoring, dosing, and considerations in this population.

Real-World Experience of Vitiligo Patients: A Retrospective Chart Review.

BACKGROUND: Vitiligo is a common depigmenting skin disorder with an estimated prevalence of 0.5% to 2% worldwide. OBJECTIVE: We conducted a study to characterize the presentation of vitiligo in community dermatology clinic setting in Ontario, Canada. METHODS: A retrospective cross-sectional study was performed through an electronic chart review at a community dermatology clinic with 2 sites in Ontario, Canada. RESULTS: We found a male to female ratio of 1:1.3. The average age at the time of assessment was 40.8 years (ranging from 7 to 75 years). Sixteen percent of the patients were children (less than 18 years of age). Hands were the most common location for vitiligo (55.8%). CONCLUSIONS: Our findings are in keeping with previously described epidemiologic data. To our knowledge, this is the first Canadian study looking at the population in a community setting.

Trial of Roflumilast Cream for Chronic Plaque Psoriasis.

BACKGROUND: Systemic oral phosphodiesterase type 4 (PDE-4) inhibitors have been effective in the treatment of psoriasis. Roflumilast cream contains a PDE-4 inhibitor that is being investigated for the topical treatment of psoriasis. METHODS: In this phase 2b, double-blind trial, we randomly assigned adults with plaque psoriasis in a 1:1:1 ratio to use roflumilast 0.3% cream, roflumilast 0.15% cream, or vehicle (placebo) cream once daily for 12 weeks. The primary efficacy outcome was the investigator's global assessment (IGA) of a status of clear or almost clear at week 6 (assessed on a 5-point scale of plaque thickening, scaling, and erythema; a score of 0 indicates clear, 1 almost clear, and 4 severe). Secondary outcomes included an IGA score indicating clear or almost clear plus a 2-grade improvement in the IGA score for the intertriginous area and the change in the Psoriasis Area and Severity Index (PASI) score (range, 0 to 72, with higher scores indicating worse disease). Safety was also assessed. RESULTS: Among 331 patients who underwent randomization, 109 were assigned to roflumilast 0.3% cream, 113 to roflumilast 0.15% cream, and 109 to vehicle cream. An IGA score indicating clear or almost clear at week 6 was observed in 28% of the patients in the roflumilast 0.3% group, in 23% in the roflumilast 0.15% group, and in 8% in the vehicle group (P<0.001 and P = 0.004 vs. vehicle for roflumilast 0.3% and 0.15%, respectively). Among the approximately 15% of patients overall who had baseline intertriginous psoriasis of at least mild severity, an IGA score at week 6 indicating clear or almost clear plus a 2-grade improvement in the intertriginous-area IGA score occurred in 73% of the patients in the roflumilast 0.3% group, 44% of those in the roflumilast 0.15% group, and 29% of those in the vehicle group. The mean baseline PASI scores were 7.7 in the roflumilast 0.3% group, 8.0 in the roflumilast 0.15% group, and 7.6 in the vehicle group; the mean change from baseline at week 6 was -50.0%, -49.0%, and -17.8%, respectively. Application-site reactions occurred with similar frequency in the roflumilast groups and the vehicle group. CONCLUSIONS: Roflumilast cream administered once daily to affected areas of psoriasis was superior to vehicle cream in leading to a state of clear or almost clear at 6 weeks. Longer and larger trials are needed to determine the durability and safety of roflumilast in psoriasis. (Funded by Arcutis Biotherapeutics; ARQ-151 201 ClinicalTrials.gov number, NCT03638258.).

Bimekizumab efficacy and safety in patients with moderate-to-severe plaque psoriasis who switched from adalimumab, ustekinumab or secukinumab: results from phase III/IIIb trials.

BACKGROUND: Discontinuation of biologics is common among patients with psoriasis due to treatment failure or adverse events. To achieve improvements in disease management, patients and clinicians may choose to switch biologics. OBJECTIVES: To evaluate the efficacy and safety of switching to bimekizumab from adalimumab, ustekinumab and secukinumab. METHODS: Data are reported for up to 80 weeks after patients switched to bimekizumab from adalimumab at week 24 in BE SURE, ustekinumab at week 52 in BE VIVID [upon entry into the BE BRIGHT open-label extension (OLE)] and secukinumab at week 48 in BE RADIANT (upon entry into the BE RADIANT OLE). Efficacy outcomes are reported by number of weeks after switching to bimekizumab and were split based on whether patients had achieved a ≥ 90% improvement from baseline in Psoriasis Area and Severity Index (PASI 90) at the time of switch. Treatment-emergent adverse events (TEAEs) are reported using exposure-adjusted incidence rates (EAIRs) per 100 patient-years. Trial registration: BE SURE (NCT03412747), BE VIVID (NCT03370133), BE BRIGHT (NCT03598790), BE RADIANT (NCT03536884). RESULTS: Rapid and durable improvements in clinical responses and benefits in health-related quality of life were observed among PASI 90 nonresponders who switched to bimekizumab. Most PASI 90 nonresponders achieved PASI 90 4 weeks after switching to bimekizumab from adalimumab (67%), ustekinumab (79%) and secukinumab (53%). After 48 weeks of bimekizumab, 91%, 90% and 79% of PASI 90 nonresponders had achieved PASI 90 after switching from adalimumab, ustekinumab or secukinumab, respectively. Durable improvements were also observed for PASI 100, Investigator's Global Assessment score 0/1, body surface area affected by psoriasis ≤ 1%, absolute PASI ≤ 2, and Dermatology Life Quality Index 0/1. Among PASI 90 responders, existing treatment responses were maintained or improved after switching to bimekizumab. The majority of TEAEs were mild or moderate. EAIRs were generally similar between active-comparator treatment periods and after switching to bimekizumab. EAIRs typically decreased with a longer duration of bimekizumab exposure. CONCLUSIONS: High proportions of patients who did not adequately respond to adalimumab, ustekinumab or secukinumab achieved high levels of skin clearance after switching to bimekizumab. Bimekizumab was well tolerated and there were no new safety findings.

Once-daily roflumilast foam 0.3% for scalp and body psoriasis: a randomized, double-blind, vehicle-controlled phase IIb study.

BACKGROUND: Scalp psoriasis affects most patients with psoriasis, but it can be difficult to treat. OBJECTIVES: To evaluate the efficacy and safety of once-daily roflumilast foam 0.3% on scalp and body psoriasis. METHODS: In a phase IIb randomized controlled trial, adults and adolescents aged ≥ 12 years with scalp and body psoriasis were randomized (2 : 1) to roflumilast foam 0.3% or vehicle for 8 weeks. The primary efficacy endpoint was scalp Investigator Global Assessment (S-IGA) success (score of 'clear' or 'almost clear' plus ≥ 2-grade improvement from baseline) at week 8. Safety and tolerability were also evaluated. RESULTS: Significantly more roflumilast-treated patients (59.1%) than vehicle-treated patients (11.4%) achieved S-IGA success at week 8 (P < 0.001); differences favoured roflumilast as early as the first postbaseline visit at week 2 (P < 0.001). Significant improvements were also seen for secondary endpoints, including body IGA success, Scalp Itch Numeric Rating Scale and the Psoriasis Scalp Severity Index. The safety of roflumilast was generally similar to vehicle. Patients treated with roflumilast experienced low rates of treatment-emergent adverse events (AEs), with few discontinuations due to an AE. Few patients with skin of colour (11%) and few adolescents (0.7%) were included. CONCLUSIONS: The results support the further development of roflumilast foam for treating scalp and body psoriasis.

Clindamycin phosphate 1.2%/adapalene 0.15%/benzoyl peroxide 3.1% gel for moderate-to-severe acne: Efficacy and safety results from two randomized phase 3 trials.

BACKGROUND: A three-pronged acne treatment approach-combining an antibiotic, antibacterial agent, and retinoid-may provide greater efficacy than single/double treatments. Topical clindamycin phosphate 1.2%/adapalene 0.15%/benzoyl peroxide (BPO) 3.1% gel (IDP-126) is the first fixed-dose triple-combination in development for acne. OBJECTIVE: To confirm efficacy, safety, and tolerability of IDP-126 gel in acne treatment. METHODS: Two phase 3, double-blind, 12-week studies randomized participants aged ≥9 years with moderate-to-severe acne (N = 183; N = 180) 2:1 to once-daily IDP-126 or vehicle gel. Co-primary endpoints comprised participants achieving ≥2-grade reduction from baseline in Evaluator's Global Severity Score (EGSS) and clear/almost clear skin (treatment success) and change from baseline in inflammatory/noninflammatory lesion counts. Treatment-emergent adverse events (TEAEs) were assessed. RESULTS: At week 12, 49.6% and 50.5% of participants achieved treatment success with IDP-126 versus 24.9% and 20.5% with vehicle (P < .01, both). IDP-126 also provided significantly greater reductions in inflammatory/noninflammatory lesions versus vehicle (least-squares mean percent range: 72.7% to 80.1% vs 47.6% to 59.6%; P < .001, all). Most TEAEs were of mild-moderate severity. LIMITATIONS: Inter-observer bias/variation in acne severity ratings, limited treatment duration, and population differences that may not generalize to real-world populations. CONCLUSION: The innovative fixed-dose, triple-combination IDP-126 gel was efficacious and well tolerated in 2 clinical studies of participants with moderate-to-severe acne.

Deucravacitinib versus placebo and apremilast in moderate to severe plaque psoriasis: Efficacy and safety results from the 52-week, randomized, double-blinded, placebo-controlled phase 3 POETYK PSO-1 trial.

BACKGROUND: Effective, well-tolerated oral psoriasis treatments are needed. OBJECTIVE: To compare the efficacy and safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, versus placebo and apremilast in adults with moderate to severe plaque psoriasis. METHODS: Participants were randomized 2:1:1 to deucravacitinib 6 mg every day (n = 332), placebo (n = 166), or apremilast 30 mg twice a day (n = 168) in the 52-week, double-blinded, phase 3 POETYK PSO-1 trial (NCT03624127). Coprimary end points included response rates for ≥75% reduction from baseline in Psoriasis Area and Severity Index (PASI 75) and static Physician's Global Assessment score of 0 or 1 (sPGA 0/1) with deucravacitinib versus placebo at week 16. RESULTS: At week 16, response rates were significantly higher with deucravacitinib versus placebo or apremilast for PASI 75 (194 [58.4%] vs 21 [12.7%] vs 59 [35.1%]; P < .0001) and sPGA 0/1 (178 [53.6%] vs 12 [7.2%] vs 54 [32.1%]; P < .0001). Efficacy improved beyond week 16 and was maintained through week 52. Adverse event rates with deucravacitinib were similar to those with placebo and apremilast. LIMITATIONS: One-year duration, limited racial diversity. CONCLUSION: Deucravacitinib was superior to placebo and apremilast across multiple efficacy end points and was well tolerated in moderate to severe plaque psoriasis.

Long-term safety and efficacy of risankizumab for the treatment of moderate-to-severe plaque psoriasis: Interim analysis of the LIMMitless open-label extension trial up to 5 years of follow-up.

BACKGROUND: Psoriasis is a chronic, inflammatory skin disease often requiring long-term therapy. OBJECTIVE: To evaluate the long-term safety and efficacy of risankizumab in patients with psoriasis. METHODS: LIMMitless is an ongoing phase 3, open-label extension study evaluating the long-term safety and efficacy of continuous risankizumab 150 mg every 12 weeks for adults with moderate-to-severe plaque psoriasis following multiple phase 2/3 base studies. This interim analysis assessed safety (ie, monitored treatment-emergent adverse events [TEAEs]) through 304 weeks. Efficacy assessments included determining the proportion of patients who achieved ≥90% or 100% improvement in Psoriasis Area and Severity Index (PASI 90/100), static Physician's Global Assessment of clear/almost clear (sPGA 0/1), and Dermatology Life Quality Index of no effect on patient's life (DLQI 0/1) through 256 weeks. RESULTS: Among 897 patients randomized to risankizumab in the base studies, 706 were still ongoing at data cutoff. Rates of TEAEs, TEAEs leading to discontinuation, and TEAEs of safety interest were low. At week 256, 85.1%/52.3% of patients achieved PASI 90/100, respectively, 85.8% achieved sPGA 0/1, and 76.4% achieved DLQI 0/1. LIMITATIONS: Open-label study with no placebo or active-comparator group. CONCLUSIONS: Long-term continuous risankizumab treatment for up to 5 years was well tolerated and demonstrated high and durable efficacy.

Generalized pustular psoriasis: A global Delphi consensus on clinical course, diagnosis, treatment goals and disease management.

BACKGROUND: Generalized pustular psoriasis (GPP) is a rare and highly heterogeneous skin disease, characterized by flares of neutrophilic pustules and erythema. As a rare disease with few clinical studies and no standardized management approaches, there is a paucity of knowledge regarding GPP. OBJECTIVES: Conduct a Delphi panel study to identify current evidence and gain advanced insights into GPP. METHODS: A systematic literature review was used to identify published literature and develop statements categorized into four key domains: clinical course and flare definition; diagnosis; treatment goals; and holistic management. Statements were rated on a Likert scale by a panel of dermatologists in two rounds of online questionnaires; the threshold for consensus was agreement by ≥80%. RESULTS: Twenty-one panellists reached consensus on 70.9%, 61.8%, 100.0% and 81.8% of statements in the 'clinical course and flare definition', 'diagnosis', 'treatment goals' and 'holistic management of GPP' domains, respectively. There was clear consensus on GPP being phenotypically, genetically and immunologically distinct from plaque psoriasis. Clinical course is highly variable, with an extensive range of complications. Clinical and histologic features supporting GPP diagnosis reached high levels of agreement, and although laboratory evaluations were considered helpful for diagnosis and monitoring disease severity, there was uncertainty around the value of individual tests. All acute and long-term treatment goals reached consensus, including rapid and sustained clearance of pustules, erythema, scaling and crust, clearance of skin lesions and prevention of new flares. Potential triggers, associated comorbidities and differential diagnoses achieved low rates of consensus, indicating that further evidence is needed. CONCLUSIONS: Global consensus between dermatologists was reached on clinically meaningful goals for GPP treatment, on key features of GPP flares and on approaches for assessing disease severity and multidisciplinary management of patients. On this basis, we present a management algorithm for patients with GPP for use in clinical practice.

The burden of alopecia areata: A scoping review focusing on quality of life, mental health and work productivity.

Alopecia areata (AA) is a common inflammatory autoimmune disease of the hair which can have a significant negative impact on quality of life (QoL), mental health and productivity. The aim of this scoping review is to elucidate the burden of AA focusing on these three realms. Inclusion criteria included all original manuscripts with no restriction on study type or statistical method written in English (or having an English abstract). For QoL 40 articles were included, 85 for psychiatric comorbidities, and 9 for work/school absenteeism/presenteeism mostly consisting of cross-sectional and observational cohort studies. QoL impairment was detected in over 75% of patients and up to one-third reported extremely severe QoL impairments. Specific QoL dimensions with the greatest impact were embarrassment, social functioning, as well as shopping and/or housework. Cross-sectional studies assessing the psychological burden of adult patients with AA found that the presence of signs of anxiety and/or depression ranged from 30% to 68% and affected all age groups. Rates of work absenteeism and unemployment were significantly higher in AA patients compared to healthy controls. Up to 62% reported making major life decisions including relationships, education and career based on their AA. Additionally, the extensive camouflage techniques and time lost from work led to a strong financial burden for patients and the numerous physician visits added to the healthcare costs. The overall impact of AA stretches much further than simply being an aesthetic concern and can negatively impact every part of an individual's life. An individualized approach and effective treatments will help reduce the psychosocial consequences and distress and return patients to their normal state of health.
