Upadacitinib for moderate-to-severe atopic dermatitis: Stratified analysis from three randomized phase 3 trials by key baseline characteristics.

BACKGROUND: Atopic dermatitis (AD) is a heterogeneous inflammatory skin disease with different clinical phenotypes based on factors such as age, race, comorbidities, and clinical signs and symptoms. The effect of these factors on therapeutic responses in AD has only been scarcely studied and not for upadacitinib. Currently, there is no biomarker predicting response to upadacitinib. OBJECTIVES: Evaluate the efficacy of the oral Janus kinase inhibitor upadacitinib across patient subgroups (baseline demographics, disease characteristics and prior treatment) in patients with moderate-to-severe AD. METHODS: Data from phase 3 studies (Measure Up 1, Measure Up 2 and AD Up) were utilized for this post hoc analysis. Adults and adolescents with moderate-to-severe AD were randomized to receive once daily oral upadacitinib 15 mg, upadacitinib 30 mg or placebo; patients enrolled in the AD Up study received concomitant topical corticosteroids. Data from the Measure Up 1 and Measure Up 2 studies were integrated. RESULTS: A total of 2584 patients were randomized. A consistently greater proportion of patients achieved at least 75% improvement in the Eczema Area and Severity Index, a 0 or 1 on the validated Investigator Global Assessment for Atopic Dermatitis, and improvement in itch (including an achievement of a reduction of ≥4; and score of 0/1 in Worst Pruritus Numerical Rating Scale) with upadacitinib compared with placebo at Week 16, regardless of age, sex, race, body mass index, AD severity, body surface area involvement, history of atopic comorbidities or asthma, or previous exposure to systemic therapy or cyclosporin. CONCLUSIONS: Upadacitinib had consistently high skin clearance rates and itch efficacy across subgroups of patients with moderate-to-severe AD through Week 16. These results support upadacitinib as a suitable treatment option in a variety of patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifiers: NCT03569293 (Measure Up 1), NCT03607422 (Measure Up 2) and NCT03568318 (AD Up).

Efficacy of spesolimab for the treatment of generalized pustular psoriasis flares across pre-specified patient subgroups in the Effisayil 1 study.

Effisayil 1 was a multicentre, randomized, double-blind, placebo-controlled study of the anti-interleukin (IL)-36 receptor monoclonal antibody, spesolimab, in patients presenting with a generalized pustular psoriasis (GPP) flare. Previously published data from this study revealed that within 1 week, rapid pustular and skin clearance were observed in patients receiving spesolimab versus placebo. In this pre-specified subgroup analysis, the efficacy of spesolimab was evaluated according to patient demographic and clinical characteristics at baseline in patients receiving spesolimab (n = 35) or placebo (n = 18) on Day 1. Efficacy was by assessed by achievement of primary endpoint (Generalized Pustular Psoriasis Physician Global Assessment [GPPGA] pustulation subscore of 0 at Week 1) and key secondary endpoint (GPPGA total score of 0 or 1 at Week 1). Safety was assessed at Week 1. Spesolimab was found to be efficacious and had a consistent and favourable safety profile in patients presenting with a GPP flare, regardless of patient demographics and clinical characteristics at baseline.

Estimands for atopic dermatitis clinical trials: Expert opinion on the importance of intercurrent events.

Despite the emergence of novel targeted treatments for atopic dermatitis (AD), there is a lack of guidelines on standardizing analysis of clinical trial data. To define and estimate meaningful treatment comparisons, several factors, including intercurrent events, must be taken into account. Intercurrent events are defined as events occurring after treatment initiation that affect either the interpretation or existence of the measurements associated with clinical questions of interest. Due to the relapsing, unpredictable nature of AD, intercurrent events frequently occur in AD trials, such as use of rescue therapy for intense itch and sleep deprivation. Despite the impact of intercurrent events in AD, they are often handled in an inconsistent manner across trials, which limits results interpretation. The estimand framework is increasingly used to estimate treatment effects while accounting for intercurrent events. This review explores how guidance from the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) on the use of estimands can be applied to support AD clinical trial design and analysis. We propose that estimands are used in AD trials and defined early during trial design. The use of estimands can provide clinicians with interventional trial results that are more reflective of clinical practice, help facilitate comparisons across clinical trials, and are more informative to enable improved treatment selection for patients.

Direct comparison of risankizumab and fumaric acid esters in systemic therapy-naïve patients with moderate-to-severe plaque psoriasis: a randomized controlled trial.

BACKGROUND: Fumaric acid esters (FAEs; Fumaderm® ) are the most frequently prescribed first-line systemic treatment for moderate-to-severe plaque psoriasis in Germany. Risankizumab (Skyrizi® ) is a humanized IgG1 monoclonal antibody that specifically binds to the p19 subunit of interleukin 23. OBJECTIVES: To compare risankizumab treatment to FAEs in patients with psoriasis. METHODS: This phase III randomized, active-controlled, open-label study with blinded assessment of efficacy was conducted in Germany. Patients were randomized (1 : 1) to subcutaneous risankizumab 150 mg (weeks 0, 4 and 16) or oral FAEs at increasing doses from 30 mg daily (week 0) up to 720 mg daily (weeks 8-24). Enrolled patients were adults naïve to and candidates for systemic therapy, with chronic moderate-to-severe plaque psoriasis. Phototherapy was not allowed within 14 days before or during the study. RESULTS: Key efficacy endpoints were met at week 24 for risankizumab (n = 60) vs. FAEs (n = 60) (P < 0·001): achievement of a ≥ 90% improvement in Psoriasis Area and Severity Index (PASI; primary endpoint 83·3% vs. 10·0%), ≥ 100% improvement in PASI (50·0% vs. 5·0%), ≥ 75% improvement in PASI (98·3% vs. 33·3%), ≥ 50% improvement in PASI (100% vs. 53·3%) and a Static Physician's Global Assessment of clear/almost clear (93·3% vs. 38·3%). The rates of gastrointestinal disorders, flushing, lymphopenia and headache were higher in the FAE group. One patient receiving risankizumab reported a serious infection (influenza, which required hospitalization). There were no malignancies, tuberculosis or opportunistic infections in either treatment arm. CONCLUSIONS: Risankizumab was found to be superior to FAEs, providing earlier and greater improvement in psoriasis outcomes that persisted with continued treatment, and more favourable safety results, which is consistent with the known safety profile. No new safety signals for risankizumab or FAEs were observed.

Quality of life and patient-perceived symptoms in patients with psoriasis undergoing proactive or reactive management with the fixed-dose combination Cal/BD foam: A post-hoc analysis of PSO-LONG.

BACKGROUND: Psoriasis has important physical and psychosocial effects that extend beyond the skin. Understanding the impact of treatment on health-related quality of life (HRQoL) and patient-perceived symptom severity in psoriasis is key to clinical decision-making. OBJECTIVES: This post hoc analysis of the PSO-LONG trial data assessed the impact of long-term proactive or reactive management with fixed-dose combination calcipotriene 50 µg/g and betamethasone dipropionate 0.5 mg/g (Cal/BD) foam on patient-reported outcomes (PROs) in patients with psoriasis vulgaris. METHODS: Five hundred and twenty-one patients from the Phase 3, randomized, double-blind PSO-LONG trial were included. An initial 4-week, open-label phase of fixed-dose combination Cal/BD foam once daily (QD) was followed by a 52-week maintenance phase, at the start of which patients were randomized to a proactive management arm (Cal/BD foam twice weekly) or reactive management arm (vehicle foam twice weekly). Patient-perceived symptom severity and HRQoL were assessed using the Psoriasis Symptom Inventory (PSI), the Dermatology Life Quality Index (DLQI) and the EuroQol-5D for psoriasis (EQ-5D-5L-PSO). RESULTS: Statistically and clinically significant improvements were observed across all PRO measures. The mean difference (standard deviation) from baseline to Week 4 was -8.97 (6.18) for PSI, -6.02 (5.46) for DLQI and 0.11 (0.15) for EQ-5D-5L-PSO scores. During maintenance, patients receiving reactive management had significantly higher DLQI (15% [p = 0.007]) and PSI (15% [p = 0.0128]) and a numerically lower EQ-5D-5L-PSO mean area under the curve score than patients receiving proactive management (1% [p = 0.0842]). CONCLUSIONS: Cal/BD foam significantly improved DLQI, EQ-5D-5L-PSO and PSI scores during the open-label and maintenance phases. Patients assigned to proactive management had significantly better DLQI and PSI scores and numerically better EQ-5D-5L-PSO versus reactive management. Additionally, baseline flare was associated with worse PROs than the start of a relapse, and patients starting a relapse also had worse PROs than patients in remission.

[Quality of care for patients with atopic dermatitis in Germany-no improvements in indicators after ten years]. / Qualität der dermatologischen Versorgung von Neurodermitis in Deutschland ­ keine Verbesserung der Indikatoren nach 10 Jahren.

BACKGROUND: With AtopicHealth1, the first national care study on atopic dermatitis (AD) was conducted in 2010. At that time, about one third of the patients undergoing treatment by dermatologists showed severe limitations in quality of life, which indicated an insufficient quality of care. The aim of the present study was to characterise the current care of patients with AD undergoing dermatological treatment in comparison between different severity grades, as well as in comparison to 2010 and to psoriasis. METHODS: The Germany-wide multicentre cross-sectional study "AtopicHealth2" recorded clinical data, quality of life (DLQI), therapies, preventive behaviour and patient-defined treatment benefit (PBI). Patients with an indication for systemic therapy were considered moderately to severely affected for subgroup analyses, the others mildly affected. RESULTS: Between 2017 and 2019, 1291 patients (median age 41 years, 56.5% female) were enrolled by 111 centres. Compared with 2010, there were no improvements in quality of life (DLQI 8.5 in both studies), severity (SCORAD 45.4 vs. 42.3 in 2010) or treatment benefit (PBI 2.2 vs. 2.4 in 2010). Moderately to severely affected patients were more likely to show impaired quality of life (45.4% vs. 23.6%) and less likely to have relevant treatment benefits (PBI < 1: 21.3% vs. 13.2%) than mildly affected patients. In contrast to psoriasis, patients with AD revealed higher quality of life limitations (DLQI 8.5 vs. 6.1) and lower treatment benefit (PBI 2.2 vs. 2.8). DISCUSSION: Compared to 2010, there is no improvement in the quality of care for AD in Germany. Compared to psoriasis, patients with AD show higher burden and lower treatment benefit, which underlines the need for therapeutic innovations.

Association of sex and systemic therapy treatment outcomes in psoriasis: a two-country, multicentre, prospective, noninterventional registry study.

BACKGROUND: Few systematic data on sex-related treatment responses exist for psoriasis. OBJECTIVES: To evaluate sex differences with respect to systemic antipsoriatic treatment. METHODS: Data from patients with moderate-to-severe psoriasis in the PsoBest or Swiss Dermatology Network of Targeted Therapies (SDNTT) registries were analysed. Treatment response was defined as achieving a ≥ 75% reduction in Psoriasis Area and Severity Index (PASI 75) or PASI ≤ 3 at treatment months 3, 6 and 12, supplemented by patient-reported outcomes [i.e. Dermatology Life Quality Index (DLQI) ≤ 1 and delta DLQI ≥ 4]. RESULTS: In total, 5346 patients registered between 2007 and 2016 were included (PsoBest, n = 4896; SDNTT, n = 450). The majority received nonbiological treatment (67·3% male, 69·8% female). Women showed slightly higher PASI response rates after 3 (54·8% vs. 47·2%; P ≤ 0·001), 6 (70·8% vs. 63·8%; P ≤ 0·001) and 12 months (72·3% vs. 66·1%; P ≤ 0·004). A significantly higher proportion of women achieved a reduction in DLQI ≥ 4 [month 3: 61·4% vs 54·8% (P ≤ 0·001); month 6: 69·6% vs. 62·4% (P ≤ 0·001); month 12: 70·7% vs. 64·4% (P ≤ 0·002)]. Regarding PASI ≤ 3, women on biologics showed a significantly superior treatment response compared with men at 3 (57·8% vs. 48·5%; P ≤ 0·004) and 6 months (69·2% vs. 60·9%; P ≤ 0·018). Women in the nonbiological treatment group had a significantly better treatment response (PASI response, PASI 75 and PASI ≤ 3) over 12 months compared with men. CONCLUSIONS: We provide evidence that women experience better treatment outcomes with systemic antipsoriatic therapy than men.

Addressing challenges associated with long-term topical treatment and benefits of proactive management in patients with psoriasis.

The majority of patients with psoriasis vulgaris (chronic plaque psoriasis) can be treated successfully with short-term topical therapies. However, long-term management of psoriasis with topicals is challenging and tends to take a reactive approach to disease relapse, rather than a proactive approach aimed at maintaining disease remission. Patients are often dissatisfied with the delay in treatment response and inconvenience of applying topical treatments, and therefore frequently discontinue treatment leading to poor outcomes. Relapse is common, particularly with reactive management, as underlying residual disease can remain following initial skin clearance; some patients find that their disease at relapse may be worse than their initial symptoms. This can have a detrimental effect on patient quality of life (QoL) and increase the risk of psoriasis-associated depression. A long-term proactive management approach, with maintenance treatment following initial treatment success, could help sustain disease remission and improve clinical and QoL outcomes for patients. Treatment with fixed-dose calcipotriol 50 µg/g betamethasone dipropionate 0.5 mg/g cutaneous foam (Cal/BD foam) is effective in the short term, providing a fast onset of action and improvements in disease at 4 weeks. Results from the Phase III PSO-LONG study demonstrated that long-term proactive management was superior to reactive management in prolonging time to first relapse, reducing number of relapses and increasing days in remission in adults with psoriasis vulgaris. Furthermore, Cal/BD foam was well tolerated in PSO-LONG. No new safety concerns were identified over 52 weeks; the safety profile was consistent with that described previously. Given this, Cal/BD foam should be considered when prescribing topicals for the long-term proactive management for patients with psoriasis.

Five-year efficacy and safety of tildrakizumab in patients with moderate-to-severe psoriasis who respond at week 28: pooled analyses of two randomized phase III clinical trials (reSURFACE 1 and reSURFACE 2).

BACKGROUND: The phase III reSURFACE 1 and reSURFACE 2 (NCT01722331/NCT01729754) trials of the anti-interleukin-23p19 monoclonal antibody tildrakizumab (TIL) for psoriasis treatment are complete. OBJECTIVES: We present 5-year pooled data from reSURFACE 1 and reSURFACE 2. METHODS: reSURFACE 1 and reSURFACE 2 were double-blind, randomized, controlled studies with optional long-term extensions. Adults with moderate-to-severe chronic plaque psoriasis were randomized 2 : 2 : 1 to TIL 100 mg (TIL 100) or 200 mg (TIL 200) or placebo at weeks 0 and 4, and every 12 weeks thereafter [reSURFACE 2 included an etanercept (ETN) arm]. Efficacy outcomes included proportions of patients achieving absolute and relative improvement from baseline Psoriasis Area and Severity Index (PASI) score through week 244 in TIL responders (≥ 75% improvement from baseline PASI; PASI 75 response) continuously receiving the same dose and ETN partial responders and nonresponders (PASI < 75 response) switched to TIL 200 at week 28. Safety was assessed from adverse events (AEs) in all patients as treated. RESULTS: Efficacy analyses included 329 and 227 week 28 responders to TIL 100 and TIL 200, respectively, and 121 ETN partial responders/nonresponders switched to TIL 200 at week 28. Of TIL 100 or TIL 200 responders and ETN partial responders/nonresponders entering the extensions, 235/302, 176/213 and 85/107, respectively, were evaluated at week 244, and 88·7%, 92·5% and 81·3%, respectively, achieved PASI 75 response. Exposure-adjusted rates of serious AEs were 6·3 and 6·0 patients with events per 100 patient-years of TIL 100 and TIL 200, respectively. CONCLUSIONS: TIL treatment provided sustained disease control over 5 years in week 28 TIL responders and ETN partial responders/nonresponders, with a reassuring safety profile.

Patient-reported outcomes with risankizumab versus fumaric acid esters in systemic therapy-naïve patients with moderate to severe plaque psoriasis: a phase 3 clinical trial.

BACKGROUND: In a phase 3 clinical study, patients from Germany with moderate to severe psoriasis who were naïve to systemic treatment and received risankizumab had greater and more rapid disease improvements compared with those who received fumaric acid esters (FAEs). OBJECTIVE: To evaluate patient-reported outcomes (PROs) in patients treated with risankizumab compared with FAEs. METHODS: Adult patients were randomized 1:1 to receive either risankizumab 150 mg subcutaneous injections at weeks 0, 4 and 16 or FAEs (Fumaderm® ) provided according to the prescribing label. PRO secondary endpoints assessed were Psoriasis Symptom Scale (PSS), Dermatology Life Quality Index (DLQI), 36-Item Short Form Health Survey, version 2 (SF-36v2), Patient Benefit Index (PBI), Hospital Anxiety and Depression Scale (HADS), Patient Global Assessment (PtGA) and European Quality of Life 5 Dimensions 5 Level (EQ-5D-5L). PROs were assessed at weeks 0, 16 and 24. RESULTS: Sixty patients each were randomized to receive risankizumab or FAEs. A significant PSS improvement was observed with risankizumab vs. FAEs at weeks 16 and 24 for total and psoriasis-associated redness, itching and burning scores (P < 0.001). DLQI scores were significantly lower (reflecting better health-related quality of life) with risankizumab vs. FAEs, with least squares (LS) mean differences of -7.4 and -7.6 at weeks 16 and 24, respectively (both P < 0.001). Patients randomized to risankizumab also had larger improvements in SF-36 Physical and Mental Component Summary scores, HADS anxiety and depression scores, PtGA, and EQ-5D-5L index and visual analogue scale scores (all P ≤ 0.002) at weeks 16 and 24 compared with FAEs. PBI was significantly higher, indicating greater benefit, with risankizumab vs. FAEs, with an LS mean difference of 1.1 and 1.3 at weeks 16 and 24, respectively (both P < 0.001). CONCLUSIONS: Risankizumab provides significant benefits over FAEs in improving PROs across several dimensions in patients with moderate to severe psoriasis.

Dupilumab provides favourable long-term safety and efficacy in children aged ≥ 6 to < 12 years with uncontrolled severe atopic dermatitis: results from an open-label phase IIa study and subsequent phase III open-label extension study.

BACKGROUND: Children aged ≥ 6 to < 12 years with severe atopic dermatitis (AD) have limited treatment options. In a 16-week, randomized, placebo-controlled, phase III trial in children, dupilumab, a monoclonal antibody inhibiting interleukin (IL)-4/IL-13 signalling, significantly improved signs and symptoms with acceptable safety; longer-term safety and efficacy data are lacking. OBJECTIVES: To report the pharmacokinetic profile and long-term safety and efficacy of dupilumab in children (aged ≥ 6 to < 12 years) with severe AD. METHODS: Children (aged ≥ 6 to < 12 years) with severe AD were enrolled in a global, multicentre, phase IIa, open-label, ascending-dose, sequential cohort study and subsequent open-label extension (OLE) study. Patients received single-dose dupilumab 2 or 4 mg kg-1 followed by 8-week pharmacokinetic sampling, then 2 or 4 mg kg-1 weekly for 4 weeks (phase IIa), followed by the same weekly regimen (OLE). Primary endpoints were dupilumab concentration-time profile and treatment-emergent adverse events (TEAEs); secondary assessments included Eczema Area and Severity Index (EASI) and Peak Pruritus Numeric Rating Scale (PP-NRS) score. RESULTS: Of 38 children enrolled, 37 completed phase IIa and 33 continued to the OLE. Nonlinear, target-mediated pharmacokinetics characterized dupilumab concentrations (week 24-48 mean serum concentrations: 2 mg kg-1 , 61-77 mg L-1 ; 4 mg kg-1 , 143-181 mg L-1 ). TEAEs were mostly mild to moderate and transient; none led to treatment discontinuation. The most commonly reported TEAEs were nasopharyngitis (2 mg kg-1 , 47%; 4 mg kg-1 , 56%) and AD exacerbation (29% and 13%, respectively). Single-dose dupilumab rapidly improved AD with further improvements through week 52. Mean EASI and PP-NRS improved by -37%/-33% and -17%/-20% at week 2 (phase IIa) and -92%/-84% and -70%/-58% at week 52 (OLE), respectively. CONCLUSIONS: These safety and efficacy results support the use of dupilumab as a continuous long-term treatment for children aged ≥ 6 to < 12 years with severe AD.

Long-term efficacy of certolizumab pegol for the treatment of plaque psoriasis: 3-year results from two randomized phase III trials (CIMPASI-1 and CIMPASI-2).

BACKGROUND: Certolizumab pegol (CZP) is an Fc-free, PEGylated anti-tumour necrosis factor biologic. OBJECTIVES: To report the 3-year efficacy of CZP in plaque psoriasis, pooled from the CIMPASI-1 (NCT02326298) and CIMPASI-2 (NCT02326272) phase III trials. METHODS: Adults with moderate-to-severe psoriasis for ≥ 6 months were randomized 2 : 2 : 1 to CZP 200 mg, CZP 400 mg or placebo, every 2 weeks (Q2W) for up to 48 weeks. Patients entering the open-label period (weeks 48-144) from double-blinded CZP initially received CZP 200 mg Q2W. Patients not achieving ≥ 50% improvement in Psoriasis Area and Severity Index (PASI 50) at week 16 entered an open-label CZP 400 mg Q2W escape arm (weeks 16-144). Dose adjustments based on PASI response were permitted during open-label treatment. Outcomes included PASI 75, PASI 90 and Physician's Global Assessment (PGA) 0/1 responder rates, based on a logistic regression model (missing data imputed using Markov Chain Monte Carlo methodology). RESULTS: In total, 186 patients were randomized to CZP 200 mg Q2W and 175 to CZP 400 mg Q2W. At week 48, PASI 75/90 was achieved by 72·7%/51·3% of patients randomized to CZP 200 mg and 84·4%/62·7% randomized to CZP 400 mg. Patients entering the open-label period at week 48, from blinded treatment, received CZP 200 mg Q2W. At week 144, PASI 75/90 was achieved by 70·6%/48·7% patients randomized to CZP 200 mg and 72·9%/42·7% randomized to CZP 400 mg. At week 16, 72 placebo-randomized patients entered the CZP 400 mg Q2W escape arm; 75.7%/58.5% achieved PASI 75/90 at week 144. CONCLUSIONS: Both CZP 200 mg and 400 mg Q2W demonstrated sustained, durable efficacy, with numerically higher responses for some outcomes with 400 mg Q2W.

Pooled safety analysis of baricitinib in adult patients with atopic dermatitis from 8 randomized clinical trials.

BACKGROUND: Janus kinase (JAK) inhibition is a new mode of action in atopic dermatitis (AD); clarity about drug class safety considerations in the context of AD is important. Baricitinib, an oral, reversible, selective inhibitor of JAK1/JAK2, is in late-stage development for adult patients with moderate-to-severe AD. OBJECTIVE: To report pooled safety data for baricitinib in patients with moderate-to-severe AD in the clinical development program including long-term extension (LTE) studies. METHODS: This analysis included patient-level safety data from six double-blinded, randomized, placebo-controlled studies (one phase 2 and five phase 3), one double-blinded, randomized, LTE study and one open-label LTE study, reported in three data sets: placebo-controlled, 2-mg - 4-mg extended and All-bari AD. Safety outcomes include treatment-emergent adverse events, adverse events of special interest and abnormal laboratory changes. Proportions of patients with events and incidence rates were calculated. RESULTS: Data were collected for 2531 patients who were given baricitinib for 2247 patient-years (median duration 310 days). The frequency of serious infections, opportunistic infections and conjunctival disorders was low and similar between treatment groups in the placebo-controlled period. The most common serious infections were eczema herpeticum [n = 11, incidence rates (IR) = 0.5], cellulitis (n = 6, IR = 0.3) and pneumonia (n = 3, IR = 0.1). There were four opportunistic infections (IR = 0.2). No malignancies, gastrointestinal perforations, positively adjudicated cardiovascular events or tuberculosis were reported in the placebo-controlled period in baricitinib-treated patients. Frequency of herpes simplex was higher in the 4-mg group (6.1%) vs. the 2-mg (3.6%) and placebo group (2.7%); IRs in the extended data set (2-mg IR = 9.6; 4-mg IR = 14.5) were lower vs. the placebo-controlled data set (2-mg IR = 12.4; 4-mg IR = 21.3). In the All-bari AD data set, there were two positively adjudicated major adverse cardiovascular events (2-mg group): two venous thrombosis events (4-mg group) and one death. CONCLUSION: This integrated safety analysis in patients with moderate-to-severe AD confirms the established safety profile of baricitinib.

Patients with bullous pemphigoid and comorbid psoriasis present with less blisters and lower serum levels of anti-BP180 autoantibodies.

BACKGROUND: Although the association of bullous pemphigoid (BP) and psoriasis is well-established, the clinical and immunological features of patients with coexisting BP and psoriasis are yet to be investigated. OBJECTIVE: We aimed to estimate the prevalence of psoriasis amongst patients with BP and to elucidate the clinical and immunological characteristics of BP patients with comorbid psoriasis. METHODS: A retrospective cohort study including all consecutive patients diagnosed with BP throughout the years 2009-2019 in a tertiary referral centre. RESULTS: The study encompassed 273 patients with BP, of whom 11 (4.0%; 95% CI, 2.3-7.1%) had comorbid psoriasis. The onset of psoriasis preceded that of BP in 81.8% of patients by a median (range) latency of 26.5 (5.0-34.0) years. Compared to BP patients without psoriasis, those with BP and comorbid psoriasis were significantly younger at the onset of BP [71.8 (9.3) vs. 79.4 (9.8) years; P = 0.023], had a milder erosive phenotype [erosion/blister BPDAI mean (SD)score; 5 (4.1) vs. 22.3 (15.2); P = 0.025], lower levels of anti-BP180 NC16A serum autoantibodies [236.6 (266.3) vs. 556.2 (1323.6) U/mL; P = 0.008] and a higher prevalence of isolated linear C3 deposits (36.4% vs. 14.1%; P = 0.043) and a lower prevalence of linear immunoglobulin G deposits (36.4% vs. 68.7%; P = 0.025) along the dermal-epidermal junction by direct immunofluorescence microscopy. CONCLUSIONS: Patients with BP and comorbid psoriasis present at a younger age with milder erosive phenotype and lower levels of pathogenic autoantibodies.

International observational atopic dermatitis cohort to follow natural history and treatment course: TARGET-DERM AD study design and rationale.

INTRODUCTION: As new topical and systemic treatments become available for atopic dermatitis (AD), there is a need to understand how treatments are being used in routine clinical practice, their comparative effectiveness and their long-term safety in diverse clinical settings. METHODS AND ANALYSIS: The TARGET-DERM AD cohort is a longitudinal, observational study of patients with AD of all ages, designed to provide practical information on long-term effectiveness and safety unobtainable in traditional registration trials. Patients with physician-diagnosed AD receiving prescription treatment (topical or systemic) will be enrolled at academic and community clinical centres. Up to 3 years of retrospective medical records, 5 years of prospective medical records, and optional biological samples and patient-reported outcomes will be collected. The primary aims include characterisation of AD treatment regimens, evaluation of response to therapy, and description of adverse events. ETHICS AND DISSEMINATION: TARGET-DERM has been approved by a central IRB (Copernicus Group IRB, 5000 Centregreen Way Suite 200, Cary, North Carolina 27513) as well as local and institutional IRBs. No additional Ethics Committee reviews. Results will be reviewed by a publications committee and submitted to peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03661866, pre-results.

Tofacitinib in psoriatic arthritis patients: skin signs and symptoms and health-related quality of life from two randomized phase 3 studies.

BACKGROUND: Psoriatic arthritis (PsA) is a chronic, systemic immune-mediated inflammatory musculoskeletal disease. The onset of dermatologic symptoms often precedes rheumatic manifestations. Tofacitinib is an oral Janus kinase inhibitor for the treatment of PsA that has been shown to improve dermatologic symptoms in patients with PsA. OBJECTIVES: To investigate the efficacy of tofacitinib in improving dermatologic endpoints in adult patients with active PsA. METHODS: This analysis included data from two placebo-controlled, double-blind, phase 3 studies in patients with active PsA and an inadequate response (IR) to ≥1 conventional synthetic disease-modifying antirheumatic drug (csDMARD) who were tumor necrosis factor inhibitor (TNFi)-naïve (OPAL Broaden; NCT01877668) or an IR to ≥1 TNFi (OPAL Beyond; NCT01882439). Patients had active plaque psoriasis at screening and received a stable dose of one csDMARD during the study. Patients were randomized to tofacitinib 5 mg twice daily (BID), 10 mg BID, adalimumab 40 mg subcutaneous injection once every 2 weeks (OPAL Broaden only) or placebo (to Month 3). Dermatologic endpoints: Psoriasis Area and Severity Index (PASI) total score; PASI90 overall; PASI75 and PASI90 by baseline PASI severity; Physician's Global Assessment of Psoriasis; Nail Psoriasis Severity Index; Dermatology Life Quality Index total and sub-dimension scores; Itch Severity Item; and Patient's Global Joint and Skin Assessment-Visual Analog Scale-Psoriasis question. RESULTS: In patients with active PsA, including those stratified by mild or moderate/severe dermatologic symptoms, greater improvements from baseline and percentage of responders were observed in tofacitinib-treated patients vs. placebo for the majority of analyzed dermatologic endpoints at Months 1 and 3, and improvements were maintained to Month 12 in OPAL Broaden and Month 6 in OPAL Beyond. Similar effects were observed in adalimumab-treated patients vs. placebo in OPAL Broaden across dermatologic endpoints. CONCLUSIONS: Tofacitinib provides a treatment option for patients with active PsA, including the burdensome dermatologic symptoms of PsA.

Secukinumab is effective in treatment of moderate-to-severe plaque psoriasis: real-life effectiveness and safety from the PROSPECT study.

BACKGROUND: Secukinumab, a fully human anti-interleukin-17A monoclonal antibody, has demonstrated efficacy and safety in patients with moderate-to-severe psoriasis. Trial protocols specify transition periods and prohibit concomitant psoriasis medication. Data are therefore needed on secukinumab effectiveness and safety in routine clinical practice. OBJECTIVES: The PROSPECT study assesses prior and concomitant psoriasis treatments and transition periods in subjects receiving secukinumab. Here, we report interim effectiveness and safety data for secukinumab in the context of prior and concomitant treatments. METHODS: PROSPECT is an ongoing 24-week, single-cohort, non-interventional study. Subjects with moderate-to-severe psoriasis with a decision to receive secukinumab 300 mg were included. RESULTS: Of 1988 subjects, 1238/1988 (62.4%) were male, and mean age was 48.1 ± 13.7 years. Mean baseline Psoriasis Area and Severity Index (PASI) score was 17.7 ± 12.5. 90.9% of subjects had prior systemic treatment. Concomitant treatment was recorded in 44.3% of subjects. Median duration of transition period was 14.0, 30.0 and 44.5 days from prior topical, conventional systemic and biologic treatments. At Week 24, PASI75/90/100 was reached by 86.1%, 68.5% and 39.7% of subjects who started secukinumab treatment at baseline. No unexpected safety signals were observed. CONCLUSION: PROSPECT provides a large prospective real-world analysis of secukinumab treatment and includes prior and concomitant use of psoriasis treatments in subjects receiving secukinumab in a real-world setting. Secukinumab effectiveness and safety were comparable to that seen in the phase 2/3 secukinumab clinical trial programme.
