Introduction The phase 3 PSO LONG study (NCT02899962) demonstrated superior efficacy of proactive (PM) versus reactive management (RM) using calcipotriene 0.005%/betamethasone dipropionate 0.064% (Cal/BD) foam in adults with psoriasis. Here, we evaluated whether certain baseline parameters had an effect on time to first relapse (TTFR), number of relapses, and assessed interactions between treatment effect. Methods PSO LONG included an initial 4-week open-label phase (once-daily Cal/BD foam) and a 52-week maintenance phase where patients were randomized to twice-weekly Cal/BD (PM) or vehicle foam (RM), with a 4-week once-daily Cal/BD foam rescue treatment for relapse. Baseline parameters analyzed using a stepwise variable selection procedure included body surface area, modified Psoriasis Area Severity Index (mPASI), Physician Global Assessment (PGA), body mass index, age, sex, Dermatology Life Quality Index, and duration of psoriasis. Continuous variables were divided into groups based on standard criteria. Results Overall, the effect of treatment on TTFR did not vary across any baseline parameters. Variables with a statistically significant effect on TTFR were: treatment group (PM vs. RM hazard ratio [HR]: 0.56; p

A stratified medicine approach for the treatment of psoriasis promises greater certainty of clinical decision making through prediction of response on the basis of clinical, pharmacological, and -omics data from an individual patient. As yet, there is no predictive model for treatment response in routine clinical use for psoriasis. The Psoriasis Stratification to Optimise Relevant Therapy (PSORT) Consortium is a United Kingdom Medical Research Council‒funded, academic‒industrial stratified medicine consortium established with the objective of discovering the predictors and stratifiers of response of psoriasis to biologic therapies. A showcase meeting was convened and attended by 80 stakeholders at the Royal College of Physicians, London, United Kingdom on 18 November 2019. The purpose was to disseminate the research findings from the PSORT consortium discovered thus far. This report summarizes the presentations made on the day and the significant advances made by PSORT toward a stratified medicine approach to the management of psoriasis.

Background The effectiveness and cost-effectiveness of biologic therapies for psoriasis are significantly compromised by variable treatment responses. Thus, more precise management of psoriasis is needed. Objectives We aim to identify subgroups of psoriasis patients treated with biologic therapies, based on changes in their disease activity over time, that may better inform patient management. Methods Here we apply latent class mixed modelling, to identify trajectory-based patient subgroups from longitudinal, routine clinical data on disease severity, as measured by the Psoriasis Area and Severity Index (PASI), from 3546 patients in the British Association of Dermatologists Biologics and Immunomodulators Register, as well as in an independent cohort of 2889 subjects pooled across four clinical trials. Results We discovered four, discrete classes of global response trajectories, each characterised in terms of time to response, size of effect and relapse. Each class was associated with differing clinical characteristics, e.g. Body Mass Index, baseline PASI, and prevalence of different manifestations. Our results were verified in a second cohort of clinical trials subjects, where similar trajectories following initiation of biologic therapy were identified. Further, we found differential associations of the genetic marker HLA-C*06:02 between our registry-identified trajectories. Conclusion These subgroups, defined by change in disease over time, may be indicative of distinct endotypes driven by different biological mechanisms and may help inform the management of patients with psoriasis. Future work will aim to further delineate these mechanisms by extensively characterising the subgroups with additional molecular and pharmacological data.

Background In practice, the goal of treatment for patients with psoriasis is to achieve almost clear or clear skin and maintain disease control, regardless of baseline disease severity. However, identifying absolute Psoriasis Area and Severity Index (PASI) values for new treatment goals is challenging, as most clinical trials report relative PASI 50, 75, 90 or 100 improvements but rarely absolute PASI values achieved. Objective Our objective was to illustrate a statistical conversion method that was developed to derive absolute PASI values from available clinical trial data on relative PASI improvements. The results of network meta‐analyses (NMAs) based on these derived data were then compared with those of NMAs based on the corresponding relative PASI improvement data for selected biologics for moderate‐to‐severe psoriasis. Methods The PASI statistical conversion method was applied to relative PASI improvement data for 11 biologic treatment regimens and placebo at 12 weeks using data from 50 published studies. The respective proportions of patients reaching absolute PASI values ≤1, 2, 3 or 5 were then calculated. Frequentist NMAs (Rücker method) were subsequently used to compare efficacy results across relative and absolute PASI data. Results The ranking of included treatment regimens for patients achieving absolute PASI 0 to 8 was aligned with results for relative PASI scores (from 100 to 60) at end of induction therapy. Across the range of PASI scores considered, the most effective treatment regimens based on both absolute and relative PASI NMAs were brodalumab 210 mg every 2 weeks and ixekizumab 80 mg every 2 weeks, followed by guselkumab 100 mg every 8 weeks and risankizumab 150 mg every 12 weeks. Conclusion Data generated using this mathematical model will be useful to inform ongoing scientific discussions on treatment goals in the absence of primary absolute PASI data for all available treatments for moderate‐to‐severe plaque psoriasis.

There is an unmet need for a treatment for psoriasis that results in complete skin clearance with a reliably quick response. Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A. We aimed to compare the efficacy and safety of bimekizumab with placebo and ustekinumab in patients with moderate to severe plaque psoriasis over 52 weeks.BE VIVID was a multicentre, randomised, double-blind, active comparator and placebo controlled phase 3 trial done across 105 sites (clinics, hospitals, research units, and private practices) in 11 countries in Asia, Australia, Europe, and North America. Adults aged 18 years or older with moderate to severe plaque psoriasis (Psoriasis Area and Severity Index [PASI] score ≥12, ≥10% body surface area affected by psoriasis, and Investigator's Global Assessment [IGA] score ≥3 on a five point scale) were included. Randomisation was stratified by geographical region and previous exposure to biologics; patients, investigators, and sponsors were masked to treatment assignment. Patients were randomly assigned (4:2:1) using an interactive response technology to bimekizumab 320 mg every 4 weeks, ustekinumab 45 mg or 90 mg (baseline weight-dependent dosing) at weeks 0 and 4, then every 12 weeks, or placebo every 4 weeks. At week 16, patients receiving placebo switched to bimekizumab 320 mg every 4 weeks. All study treatments were administered as two subcutaneous injections. Coprimary endpoints were the proportion of patients with 90% improvement in the PASI (PASI90) and the proportion of patients with an IGA response of clear or almost clear (score 0 or 1) at week 16 (non-responder imputation). Efficacy analyses included the intention-to-treat population; safety analysis included patients who received at least one dose of study treatment. This trial was registered at ClinicalTrials.gov, NCT03370133 (completed).Between Dec 6, 2017, and Dec 13, 2019, 735 patients were screened and 567 were enrolled and randomly assigned (bimekizumab 320 mg every 4 weeks n=321, ustekinumab 45 mg or 90 mg every 12 weeks n=163, placebo n=83). At week 16, 273 (85%) of 321 patients in the bimekizumab group had PASI90 versus 81 (50%) of 163 in the ustekinumab group (risk difference 35 [95% CI 27-43]; p0·0001) and four (5%) of 83 in the placebo group (risk difference 80 [74-86]; p0·0001). At week 16, 270 (84%) patients in the bimekizumab group had an IGA response versus 87 (53%) in the ustekinumab group (risk difference 30 [95% CI 22-39]; p0·0001) and four (5%) in the placebo group (risk difference 79 [73-85]; p0·0001). Over 52 weeks, serious treatment-emergent adverse events were reported in 24 (6%) of 395 patients in the bimekizumab group (including those who switched from placebo at week 16) and 13 (8%) of 163 in the ustekinumab group.Bimekizumab was more efficacious than ustekinumab and placebo in the treatment of moderate to severe plaque psoriasis. The bimekizumab safety profile was consistent with that observed in previous studies.UCB Pharma.

Ustekinumab is an effective treatment for psoriasis, but response varies between patients. The formation of anti-drug antibodies (ADAs) may explain part of this variation by reducing the free ustekinumab level. Currently, published analyses of the clinical impact of ADAs are incomplete. In this observational cross-sectional multicenter study of 340 patients, we evaluated the impact of ADAs on ustekinumab level and clinical response as assessed by the PASI. Circulating ADA levels were measured using two assays: a drug-sensitive radioimmunoassay and a drug-tolerant ELISA. Circulating ustekinumab levels were measured using an ELISA. ADAs were detected in 3.8% (95% confidence interval [CI] = 3.2–4.2) and in 10.6% (95% CI = 7.9–13.9) of patients using the radioimmunoassay and drug-tolerant ELISA, respectively. At least 85% of the ADAs were neutralizing. Compared with patients negative for ADAs, ADA positivity in the radioimmunoassay and drug-tolerant ELISA were associated with lower median ustekinumab levels (−0.62 μg/ml [95% CI = −1.190 to −0.30] and −0.74 μg/ml [95% CI = −1.09 to −0.47], respectively) and higher absolute PASI (6.6 [95% CI = 3.0–9.9] and 1.9 [95% CI = 0.4–4.0], respectively). Absence of detectable ustekinumab regardless of ADA status correlated with poor clinical outcome (median sample PASI 10.1, 6.5 [95% CI = 3.9–8.8] compared with patients positive for ustekinumab). In conclusion, substantially reduced drug exposure resulting from ADAs formation is associated with impaired clinical response.

Background Psoriasis vulgaris is commonly treated with topical corticosteroids and vitamin D analogues. Although potent and super-potent topical corticosteroids are very effective at clearing psoriasis, with short-term reactive treatment durations, symptoms usually recur after treatment discontinuation, necessitating long-term disease management strategies. A foam formulation of calcipotriol and betamethasone dipropionate (Cal/BD foam), consisting of calcipotriol 50 μg/g and betamethasone dipropionate 0.5 mg/g, is approved for the daily treatment of psoriasis for up to 4 weeks. Here, we describe a clinical trial protocol for evaluating the long-term safety and efficacy of twice-weekly Cal/BD foam as a proactive topical maintenance therapy for plaque psoriasis for up to 52 weeks. Objective The aim of this trial was to evaluate the safety and efficacy of Cal/BD foam when applied twice weekly for up to 52 weeks as proactive maintenance therapy, with the goal of preventing or delaying disease relapse as long as possible while minimizing adverse effects. Methods Once-daily Cal/BD foam treatment responders from an initial 4-week open-label period were randomized to receive Cal/BD foam or foam vehicle applied to previously cleared plaques twice weekly for up to 52 weeks. In case of relapse, affected subjects in either group received rescue therapy with once-daily Cal/BD foam for 4 weeks on active areas. Thus, the trial (NCT02899962) compared the long-term use of Cal/BD foam in a proactive approach with a conventional, reactive approach. Planned Outcomes Efficacy endpoints included the time to first relapse, the number of relapse-free days, and the number of relapses during the maintenance phase. Safety assessments included adverse events, incidence of rebound, local safety and tolerability scores, and effects on calcium metabolism and hypothalamic–pituitary–adrenal axis function.

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.

Summary Background Patients with plaque psoriasis treated with biologic therapies need more efficacious, safe and convenient treatments to improve quality of life. Risankizumab and secukinumab inhibit interleukin‐23 and interleukin‐17A, respectively, and are effective in adult patients with moderate‐to‐severe plaque psoriasis but have different dosing regimens. Objectives To compare directly the efficacy and safety of risankizumab vs. secukinumab over 52 weeks. Methods IMMerge was an international, phase III, multicentre, open‐label, efficacy–assessor‐blinded, active‐comparator study, in which adult patients with chronic, moderate‐to‐severe plaque psoriasis were randomized in a 1 : 1 ratio to treatment with risankizumab 150 mg or secukinumab 300 mg. Primary efficacy endpoints were the proportions of patients achieving ≥ 90% improvement from baseline in Psoriasis Area and Severity Index (PASI 90) at week 16 (noninferiority comparison with margin of 12%) and week 52 (superiority comparison). Results In total 327 patients from nine countries were treated with risankizumab (n = 164) or secukinumab (n = 163). Risankizumab was noninferior to secukinumab in the proportion of patients achieving PASI 90 at week 16 [73·8% vs. 65·6%; difference of 8·2%, 96·25% confidence interval (CI)−2·2 to 18·6; within the 12% noninferiority margin] and superior to secukinumab at week 52 (86·6% vs. 57·1%; difference of 29·8%, 95% CI 20·8–38·8; P < 0·001), thus meeting both primary endpoints. All secondary endpoints (PASI 100, static Physician's Global Assessment 0 or 1, and PASI 75) at week 52 demonstrated superiority for risankizumab vs. secukinumab (P < 0·001). No new safety concerns were identified. Conclusions At week 52, risankizumab demonstrated superior efficacy and similar safety with less frequent dosing compared with secukinumab., What is already known about this topic? The need remains for treatments with sustained efficacy and a more convenient dosing schedule in moderate‐to‐severe psoriasis.Risankizumab and secukinumab are indicated for the treatment of adults with moderate‐to‐severe plaque psoriasis and target interleukin‐23 and interleukin‐17, respectively.To date, risankizumab and secukinumab have not been directly compared. What does this study add? IMMerge directly compared the safety and efficacy of risankizumab and secukinumab in patients with moderate‐to‐severe plaque psoriasis using ≥ 90% improvement in Psoriasis Area and Severity Index at weeks 16 (noninferiority) and 52 (superiority) as primary endpoints.In terms of efficacy risankizumab was noninferior to secukinumab at week 16 and superior to secukinumab at week 52 of treatment based on primary endpoint analyses. The two medications had a similar safety profile. Linked Comment: Schmitt-Egenolf. Br J Dermatol 2021; 184: 3–4. Plain language summary available online

Introduction Patients with plaque psoriasis experience a variety of signs and symptoms that can impact daily life, which may not be evaluated by clinician-reported outcomes. This study aimed to develop and assess the content validity of a new patient-reported outcome (PRO) measure to capture patient experiences of the signs, symptoms and impacts of psoriasis and aid integration of the patient perspective in treatment benefit-risk decision-making. Methods The psoriasis symptoms and impacts measure (P-SIM) was developed based on a literature search and interviews with five clinical experts in psoriasis to identify frequent signs, symptoms and impacts of psoriasis. Hybrid concept elicitation, cognitive debriefing and usability testing interviews were conducted with moderate to severe psoriasis patients to evaluate the content validity and patient understanding of the preliminary P-SIM. The preliminary P-SIM was refined using initial quantitative analyses of phase 2b data from psoriasis patients to inform the removal of any items. Results A preliminary 19-item P-SIM was developed for administration on a hand-held electronic tablet device using a 0–10 numerical response scale over a 24-h recall period. Patient interviews and testing demonstrated most patients interpreted the items and responses as intended, would not re-word any items, felt the responses matched the items and rated the device as easy to use. After quantitative testing, five items were removed from the preliminary 19-item measure because of conceptual overlap, floor effects and/or skewed distributions to generate the final 14-item P-SIM. Conclusions The P-SIM questionnaire has good content validity; patients reported it was easy to understand and reflective of their experiences. Following psychometric validation, the P-SIM may be a useful PRO measure for capturing the signs, symptoms and impacts of psoriasis and may support clinician-reported outcomes when assessing treatment benefits in clinical trials.

Stratified medicine is the tailoring of treatment to the individual characteristics of each patient. This is a challenging task in the context of psoriasis, a complex disease with a variety of phenotypic presentations and a comorbidity burden that extends beyond cutaneous manifestations. In recent years, considerable progress has been made in understanding the immunology of psoriasis, and this has informed the development of increasingly precise and efficacious therapies. However, not all patients respond to biologic therapy, and access is limited to patients with moderate to severe disease. However, subpopulations of patients are emerging with distinct patterns of response to therapy, largely determined by clinical and pharmacogenomic factors. Despite progress to date, the natural history of psoriasis remains poorly understood. It is likely that disease onset, progression, development of comorbidities and response to therapy are due to a combination of genetic, inflammatory and environmental factors. We envision that a greater understanding of the natural history of psoriasis will be a key factor in progressing a stratified medicine approach to patient care, as will earlier intervention in the course of the disease.

Background Cumulative clinical improvement and speed of improvement are important to psoriasis patients. Objective Compare cumulative benefits of biologics over 12 to 16 weeks in the treatment of moderate to severe psoriasis. Methods A systematic literature review identified phase III trial data on Psoriasis Area and Severity Index (PASI) responses for biologics during 12 and 16 weeks of treatment. Cumulative clinical benefit, measured by the area under the curve for PASI ≥75% improvement (PASI 75), ≥90% improvement (PASI 90), and 100% improvement (PASI 100), was compared using the network meta-analysis and Bayesian methodology on the relative probability of achieving percentage of maximum area under the curve. Results Among biologics approved for psoriasis treatment, anti–interleukin-17 biologics demonstrated consistently greater cumulative clinical benefits on PASI 75, PASI 90, and PASI 100 over the 12- or 16-week period than anti–interleukin-23 and other biologics. For biologics with 12-week data, ixekizumab and brodalumab showed greater cumulative benefits for PASI 75, PASI 90, and PASI 100 than secukinumab, followed by guselkumab, infliximab, adalimumab, ustekinumab, and etanercept. Ixekizumab showed greater cumulative benefits than all other biologics reporting 16-week data. Limitations Recently approved biologics were not included. Conclusion Ixekizumab (at 12 weeks and 16 weeks) and brodalumab (at 12 weeks) had greater cumulative clinical benefit than all of other biologics studied.

BACKGROUND The cardiovascular safety profile of biologic therapies used for psoriasis is unclear. OBJECTIVES To compare the risk of major cardiovascular events (CVEs; acute coronary syndrome, unstable angina, myocardial infarction and stroke) in patients with chronic plaque psoriasis treated with adalimumab, etanercept or ustekinumab in a large prospective cohort.METHODS Prospective cohort study examining the comparative risk of major CVEs was conducted using the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR). The main analysis compared adults with chronic plaque psoriasis receiving ustekinumab with tumour necrosis-α inhibitors (TNFi: etanercept and adalimumab) while the secondary analyses compared ustekinumab, etanercept, or methotrexate against adalimumab. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using overlap weights by propensity score to balance baseline covariates among comparison groups.RESULTS We included 5,468 biologic-naïve patients subsequently exposed (951 ustekinumab; 1,313 etanercept; and 3,204 adalimumab) in the main analysis. The secondary analyses also included 2,189 patients receiving methotrexate. The median (p25 - p75) follow up times for patients using ustekinumab, TNFi, adalimumab, etanercept and methotrexate were: 2.01 (1.16 - 3.21), 1.93 (1.05 - 3.34), 1.94 (1.09 - 3.32), 1.92 (0.93 - 3.45) and 1.43 (0.84 - 2.53) years, respectively. Ustekinumab, TNFi, adalimumab, etanercept and methotrexate groups had 7, 29, 23, 6 and 9 patients experiencing major CVEs, respectively. No differences in the risk of major CVEs were observed between biologic therapies (adjusted HR for ustekinumab vs TNFi: 0.96 [95%CI 0.41 - 2.22]; ustekinumab vs adalimumab: 0.81 [0.30 - 2.17]; etanercept vs adalimumab: 0.81 [0.28 - 2.30]) and methotrexate against adalimumab (1.05 [0.34 - 3.28]). CONCLUSIONS In this large prospective cohort study, we found no significant differences in the risk of major CVEs between three different biologic therapies and methotrexate. Additional studies, with longer term follow-up, are needed to investigate the potential effects of biologic therapies on incidence of major CVEs.

Introduction: Skin conditions are common and highly varied in their etiology; therefore, a diverse array of therapeutics are utilized. Drug safety studies in dermatology can be challenging as there are over 3000 diagnoses to consider. As a result, dermatologists rely on data from multiple sources including clinical trials and real-world evidence.Areas covered: In this review, we cover the main sources of safety data available, their strengths and weaknesses and how dermatologists should utilize such data. We use real-world examples of the different types of adverse events reported and how they are best captured by either randomized controlled trials or post-marketing pharmacovigilance methods. With multiple new therapies in dermatology, such as dupilumab for atopic dermatitis and janus-kinase inhibitors for alopecia areata the specialty is awash with evolving high-level evidence for their use. It is important to understand the optimal way to assess safety from trials but also appreciate the need for ongoing capture of safety data in clinical practice.Expert opinion: In dermatology, there is a plethora of conditions to treat and clinical trials, post-marketing surveillance, such as drug registries and spontaneous reporting, all enable dermatologists to gain a more comprehensive understanding of the safety profiles of drugs being used.

The standard of care for suspected cancer referrals in the National Health Service (NHS) is two weeks from presentation to specialist review.1 National hospital data has shown a 70.4% median reduction in Two Week Wait (TWW) referrals for suspected cancer as a direct result of the COVID‐19 pandemic and the national lockdown.2 Colleagues from our institution reported a 56.4% reduction in TWW suspected skin cancer referrals in April 2020.3 This trend is reflected in our dermatopathology workload data. The number of suspected cancer referrals began to climb steadily once restrictions were relaxed.2 Our dermatopathology workload normalised in September 2020.

Introduction Rapid improvement of psoriasis is valued by patients and should be considered to be an important factor in treatment selection. We investigated Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) response rates within the first 12 weeks of treatment to compare the rapid response of 11 biologic therapies for moderate-to-severe psoriasis using Bayesian and Frequentist network meta-analyses (NMA). Methods A systematic literature review was conducted to identify phase 3, double-blind, randomized, controlled trials for adult patients with moderate-to-severe psoriasis treated with interleukin (IL)-17 (brodalumab, ixekizumab, secukinumab), IL-12/-23 (ustekinumab), IL-23 (guselkumab, risankizumab, tildrakizumab), or tumor necrosis factor inhibitors (adalimumab, certolizumab pegol, etanercept, infliximab). Outcome measures extracted from 32 publications were ≥ 75, ≥ 90, or 100% improvement in PASI score (PASI 75, PASI 90, or PASI 100, respectively) at weeks 2, 4, 8, and 12 and DLQI (0,1), where score (0,1) indicates no effect on patient's life, at week 12. Bayesian NMA (BNMA) used fixed-treatment effect and random-baseline effect, normal independent models. Frequentist NMA (fNMA) was conducted as sensitivity analyses to test the robustness of the findings. Results Based on BNMA and fNMA, brodalumab and ixekizumab showed the most rapid treatment effects on PASI 75 at weeks 2, 4, and 8 and on PASI 90 and PASI 100 at weeks 2, 4, 8, and 12; ixekizumab overlapped with risankizumab on PASI 75 at week 12. Brodalumab, ixekizumab, and secukinumab yielded higher DLQI (0,1) gains at week 12 compared to all of the other biologics studied. Additional measures of quality of life were not assessed in this report. Conclusions Ixekizumab and brodalumab provide the most rapid response and earliest clinical benefit at week 2 among all of the biologics studied, including other biologic treatments such as secukinumab, ustekinumab, guselkumab, adalimumab, and etanercept. BNMA and fNMA results showed similar relative effect estimates and treatment rankings. Funding Eli Lilly and Company.

Introduction We review the literature evaluating certolizumab in psoriasis and report our experience of treatment outcomes in a joint dermatology and rheumatology clinic. Methods Patients with concomitant psoriatic arthritis (PsA) and psoriasis who had been commenced on certolizumab were included within our retrospective review. Data was collected for patient demographics, Patient Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI) and previous treatments. The literature was systematically searched using Pubmed and Scopus. Results Very recent results from the CIMPASI-1 and CIMPASI-2 studies have demonstrated the high efficacy of certolizumab in the treatment of psoriasis at both week 16 and 48. Pooled results from these studies showed a PASI75 at week 16 and week 48 of 82% and 83.6% respectively, in the certolizumab 400 mg group. In our cohort of eight patients (two female; six male; median age 49 and mean PASI of 20.8) all had failed at least two systemic non-biologic agents. Objective improvements were observed in seven patients, with five achieving PASI90 and two demonstrating either PASI75 or PASI50. Conclusion Certolizumab is efficacious in both psoriasis and PsA, including in patients who are biologic failures, and could be considered as an alternative treatment modality.

Introduction Plaque psoriasis can significantly impact patients’ quality of life. We assessed psychometric properties of the Psoriasis Symptoms and Impacts Measure (P-SIM), developed to capture patients’ experiences of signs, symptoms and impacts of psoriasis. Methods Pooled, blinded, 16-week data from 1002 patients in the BE VIVID and BE READY bimekizumab phase 3 trials were analysed. The suitability of the P-SIM missing score rule (weekly scores considered missing if ≥ 4 daily scores were missing) was assessed. Test–retest reliability was evaluated using intraclass correlation coefficients (ICCs). Convergent validity was assessed between P-SIM and relevant patient-reported outcome (PRO) (Dermatology Life Quality Index [DLQI], DLQI item 1 [skin symptoms], Patient Global Assessment of Psoriasis) and clinician-reported outcome (ClinRO) scores (Psoriasis Area and Severity Index [PASI], Investigator’s Global Assessment [IGA]) at baseline and week 16. Known-groups validity was assessed, comparing P-SIM scores between patient subgroups predefined using PASI/IGA scores. Sensitivity to change over 16 weeks was evaluated; responder definition (RD) thresholds were explored. Results The missing score rule used did not impact P-SIM scores. Test–retest reliability analyses demonstrated excellent score reproducibility (ICC 0.91–0.98). Inter-item correlations at baseline and week 16 were strong (> 0.5), apart from “choice of clothing” with “skin pain” and “burning” at baseline (both 0.49). All P-SIM scores were moderately to strongly correlated with other outcomes, demonstrating convergent validity, apart from ClinROs (PASI, IGA) at baseline that had low variability. P-SIM scores discriminated known groups at week 16, confirming known-groups validity. Changes from baseline to week 16 in P-SIM and other clinically relevant outcomes were strongly correlated (> 0.5; weaker with ClinROs), establishing sensitivity to change. Anchor-based RD analyses determined a four-point P-SIM item score decrease as indicative of marked clinically meaningful improvement. Conclusion P-SIM scores demonstrated good reliability, validity and sensitivity to change. A four-point RD threshold could be used to assess 16-week treatment effects.

Introduction This analysis assessed the psychometric properties of the Psoriasis Symptoms and Impacts Measure (P-SIM), a novel patient-reported outcome (PRO) tool designed to capture patient experiences of the signs, symptoms and impacts of psoriasis. Methods Blinded data from the BE RADIANT phase 3b trial of bimekizumab were analysed. In BE RADIANT, patients were randomised 1:1 to bimekizumab 320 mg every 4 weeks (Q4W) or secukinumab 300 mg (weekly until Week 4, then Q4W). Three items (itching, skin pain and scaling) of the P-SIM were electronically assessed throughout the trial and were scored from 0 to 10 (none to very severe signs/symptoms/impacts). Test–retest reliability was determined using intraclass correlations. Convergent validity was assessed between P-SIM and other relevant PRO and clinician-reported outcome (ClinRO) scores. Known-groups validity was assessed by comparing mean P-SIM item scores between patient subgroups based on the Psoriasis Area and Severity Index (PASI)/Investigator’s Global Assessment (IGA) scores. Responsiveness was assessed via correlations between changes from baseline in P-SIM item scores and other relevant PRO and ClinRO scores. Anchor-based responder analyses and empirical cumulative distribution function (eCDF) curves determined responder thresholds. Results The three P-SIM items yielded high intraclass coefficients (> 0.70). By Week 48, the three P-SIM items had moderate (> 0.30 and ≤ 0.50) to strong (> 0.50) correlations with other PROs and weaker correlations with ClinROs, demonstrating good convergent validity. For almost all known-group comparisons, statistically significant between-subgroup score differences were seen across all three P-SIM items. Changes from baseline in the P-SIM and other relevant outcomes were above the acceptable threshold of ≤ 0.30, demonstrating sensitivity to change. Anchor-based analyses determined a ≥ four-point reduction from baseline to indicate marked clinically meaningful improvement for the P-SIM. Conclusion These results support the validity, reliability and sensitivity to change of the P-SIM in assessing key symptoms (itching, skin pain and scaling) in patients with moderate to severe plaque psoriasis.

Background Certolizumab pegol (CZP) is an Fc-free, PEGylated anti-tumor necrosis factor biologic. Objectives To report three-year outcomes from the CIMPACT (NCT02346240) phase 3, CZP in moderate to severe plaque psoriasis, randomized controlled trial. Methods Adults were randomized 3:3:3:1 to CZP 200 mg every other week (Q2W), CZP 400 mg Q2W, etanercept biweekly, or placebo. At Week 16, CZP- and etanercept-treated PASI 75 responders were re-randomized to CZP 200 mg Q2W, CZP 400 mg Q4W, CZP 400 mg Q2W, or placebo for maintenance treatment; PASI 75 non-responders entered an open-label escape CZP 400 mg Q2W arm. Patients entering the open-label extension (OLE; Weeks 48-144) from blinded treatment received CZP 200 mg Q2W. Results Double-blinded results have been reported previously. 261 patients received 200 mg Q2W upon OLE entry. PASI 75 response was maintained in patients continuing 200 mg Q2W treatment through Weeks 16-144 (Week 144: 96.2%). In patients dosed down at Week 48 (double-blinded 400 to 200 mg Q2W), PASI 75 decreased (Week 48: 98.7%; Week 144: 85.9%). In patients who received placebo through Weeks 16-48, PASI 75 response decreased (Week 48: 60.4%), then increased following Week 48 switch to 200 mg Q2W (Week 144: 95.1%). 48 and 36 patients initially randomized to 200 and 400 mg Q2W, respectively, were Week 16 PASI 75 non-responders and entered the escape arm; at Week 144, 71.8% and 78.2% achieved PASI 75. No new safety signals were identified. Conclusions Response to CZP was durable over three years; no new safety signals were identified.

BackgroundIndirect excess morbidity has emerged as a major concern in the COVID-19 pandemic. People with psoriasis may be particularly vulnerable to this because of prevalent anxiety and depression, multimorbidity and therapeutic use of immunosuppression.ObjectiveCharacterise the factors associated with worsening psoriasis in the COVID-19 pandemic, using mental health status (anxiety and depression) as the main exposure of interest.MethodsGlobal cross-sectional study using a primary outcome of self-reported worsening of psoriasis. Individuals with psoriasis completed an online self-report questionnaire (PsoProtectMe; Psoriasis Patient Registry for Outcomes, Therapy and Epidemiology of COVID-19 Infection Me) between May 2020 and January 2021. Each individual completed a validated screen for anxiety (Generalized Anxiety Disorder-2) and depression (Patient Health Questionnaire-2). Odds ratios (OR) and 95% confidence intervals (CI) were estimated using multivariable logistic regression.Results4,043 people with psoriasis (without COVID-19) from 86 countries self-reported to PsoProtectMe (mean age 47.2 years [SD 15.1]; mean BMI 27.6kg/m2 [SD 6.0], 2,684 [66.4%] female and 3,016 [74.6%] of white European ethnicity). 1,728 (42.7%) participants (1322 [77%] female) reported worsening of their psoriasis in the pandemic. A positive screen for anxiety or depression associated with worsening psoriasis in age and gender adjusted (OR 2.04, 95% CI 1.77-2.36), and fully adjusted (OR 2.01, 95% CI 1.72-2.34) logistic regression models. Female sex, obesity, shielding behaviour and systemic immunosuppressant non-adherence also associated with worsening psoriasis. The commonest reason for non-adherence was concern regarding complications related to COVID-19.ConclusionsThese data indicate an association between poor mental health and worsening psoriasis in the pandemic. Access to holistic care including psychological support may mitigate potentially long-lasting effects of the pandemic on health outcomes in psoriasis. The study also highlights an urgent need to address patient concerns about immunosuppressant-related risks, which may be contributing to non-adherence.

Many studies have investigated risk factors for poor outcomes following COVID-19; these are important to be able to plan targeted prevention and/or intervention. A UK cohort study found that a composite variable of autoimmune diseases, representing rheumatoid arthritis, lupus or psoriasis, was associated with an increased risk of death due to COVID-19 (hazard ratio 1.19, 95% confidence intervals [CI] 1.11-1.27).

There are concerns that immunomodulatory therapies may increase the risks of developing basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (SCC) in patients with moderate-severe psoriasis. A systematic review showed that psoriasis patients were significantly more likely to develop SCC than the general population, though included studies lacked adequate comparator cohorts and adjustment for relevant confounding factors including heterogeneity between BCC and SCC in association with phototherapy and immunomodulatory therapies and lacked data on newer biologic therapies. We therefore followed-up a large prospective patient cohort to determine whether the risks of developing BCC and SCC are increased in patients with psoriasis receiving biologic therapy compared with those treated with non-biologic systemic therapies only.

Background: Registry data suggest that people with immune-mediated inflammatory diseases (IMIDs) receiving targeted systemic therapies have fewer adverse coronavirus disease 2019 (COVID-19) outcomes compared with patients receiving no systemic treatments. Objectives: We used international patient survey data to explore the hypothesis that greater risk-mitigating behaviour in those receiving targeted therapies may account, at least in part, for this observation. Methods: Online surveys were completed by individuals with psoriasis (globally) or rheumatic and musculoskeletal diseases (RMDs) (UK only) between 4 May and 7 September 2020. We used multiple logistic regression to assess the association between treatment type and risk-mitigating behaviour, adjusting for clinical and demographic characteristics. We characterized international variation in a mixed-effects model. Results: Of 3720 participants (2869 psoriasis, 851 RMDs) from 74 countries, 2262 (60·8%) reported the most stringent risk-mitigating behaviour (classified here under the umbrella term 'shielding'). A greater proportion of those receiving targeted therapies (biologics and Janus Kinase inhibitors) reported shielding compared with those receiving no systemic therapy [adjusted odds ratio (OR) 1·63, 95% confidence interval (CI) 1·35-1·97]. The association between targeted therapy and shielding was preserved when standard systemic therapy was used as the reference group (OR 1·39, 95% CI 1·23-1·56). Shielding was associated with established risk factors for severe COVID-19 [male sex (OR 1·14, 95% CI 1·05-1·24), obesity (OR 1·37, 95% CI 1·23-1·54), comorbidity burden (OR 1·43, 95% CI 1·15-1·78)], a primary indication of RMDs (OR 1·37, 95% CI 1·27-1·48) and a positive anxiety or depression screen (OR 1·57, 95% CI 1·36-1·80). Modest differences in the proportion shielding were observed across nations. Conclusions: Greater risk-mitigating behaviour among people with IMIDs receiving targeted therapies may contribute to the reported lower risk of adverse COVID-19 outcomes. The behaviour variation across treatment groups, IMIDs and nations reinforces the need for clear evidence-based patient communication on risk-mitigation strategies and may help inform updated public health guidelines as the pandemic continues.

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.

Background The multi-morbid burden and use of systemic immunosuppressants in people with psoriasis may confer greater risk of adverse COVID-19 outcomes but data are limited. Objective Characterize the course of COVID-19 in psoriasis and identify factors associated with hospitalization. Methods Clinicians reported psoriasis patients with confirmed/suspected COVID-19 via an international registry, PsoProtect. Multiple logistic regression assessed the association between clinical/demographic characteristics and hospitalization. A separate patient-facing registry characterized risk-mitigating behaviours. Results Of 374 clinician-reported patients from 25 countries, 71% were receiving a biologic, 18% a non-biologic and 10% no systemic treatment for psoriasis. 348 (93%) fully recovered from COVID-19, 77 (21%) were hospitalized and nine (2%) died. Increased hospitalization risk was associated with older age (multivariable-adjusted OR 1.59 per 10 years, 95% CI 1.19-2.13), male sex (OR 2.51, 95% CI 1.23-5.12), non-white ethnicity (OR 3.15, 95% CI 1.24-8.03) and comorbid chronic lung disease (OR 3.87, 95% CI 1.52-9.83). Hospitalization was more frequent in patients using non-biologic systemic therapy than biologics (OR 2.84, 95% CI 1.31-6.18). No significant differences were found between biologic classes. Independent patient-reported data (n=1,626 across 48 countries) suggested lower levels of social isolation in individuals receiving non-biologic systemic therapy compared to biologics (OR 0.68, 95% CI 0.50-0.94). Conclusion In this international moderate-severe psoriasis case series, biologics use was associated with lower risk of COVID-19-related hospitalization than non-biologic systemic therapies, however further investigation is warranted due to potential selection bias and unmeasured confounding. Established risk factors (being older, male, non-white ethnicity, comorbidities) were associated with higher hospitalization rates. Clinical Implications We identify risk factors for COVID-19-related hospitalization in psoriasis patients, including older age, male sex, non-white ethnicity and comorbidities. Use of biologics was associated with lower hospitalization risk than non-biologic systemic therapies., Capsule summary: In this global registry-based study, risk factors for COVID-19-related hospitalization in psoriasis patients were older age, male sex, non-white ethnicity and comorbidities. Use of biologics was associated with lower hospitalization risk than non-biologic systemic treatment.

Summary Background Certolizumab pegol (CZP) is an Fc‐free, PEGylated anti‐tumour necrosis factor biologic. Objectives To report 3‐year safety data from three phase III trials of CZP in adults with plaque psoriasis. Methods Data were pooled from CIMPASI‐1 (NCT02326298), CIMPASI‐2 (NCT02326272) and CIMPACT (NCT02346240). Included patients had moderate‐to‐severe plaque psoriasis of ≥ 6 months’ duration; had been randomized to CZP 200 mg every 2 weeks (Q2W) (400 mg at weeks 0, 2 and 4) or CZP 400 mg Q2W; and had received at least one dose of CZP with up to 144 weeks of exposure. Treatment‐emergent adverse events (TEAEs) were classified using MedDRA v18·1. Reported incidence rates (IRs) are incidence of new cases per 100 patient‐years (PY). Results Over 144 weeks, 995 patients received at least one dose of CZP (exposure: 2231·3 PY); 731 and 728 received at least one dose of CZP 200 mg Q2W (1211·4 PY) and/or 400 mg Q2W (1019·9 PY), respectively. The IR [95% confidence interval (CI)] of TEAEs was 144·9 (135·3–155·0) for all patients, 134·1 (123·2–145·7) for CZP 200 mg Q2W and 158·3 (145·5–171·9) for CZP 400 mg Q2W. The IR (95% CI) of serious TEAEs for all patients was 7·5 (6·4–8·8); the IRs were 6·7 (5·2–8·3) and 8·7 (6·9–10·8) for CZP 200 mg and 400 mg Q2W, respectively. Overall, 3·2% of patients reported serious infections (2·2% within each of the CZP 200 and 400 mg Q2W groups). Overall, there was one case of active tuberculosis, 16 malignancies in 14 patients and seven deaths (two considered treatment‐related). The cumulative IR of TEAEs did not increase over time. Conclusions No new safety signals were identified compared with previously reported data. Risk did not increase with longer or higher CZP exposure., What is already known about this topic? Certolizumab pegol is an Fc‐free, PEGylated, anti‐tumour necrosis factor biologic approved for adults with moderate‐to‐severe plaque psoriasis.Safety data from phase III trials in plaque psoriasis have found the incidence of adverse events to be generally similar over 16 weeks of treatment between the evaluated certolizumab pegol doses 200 mg and 400 mg every 2 weeks and placebo.Additionally, the safety profile was in line with the class over 48 weeks. What does this study add? Plaque psoriasis is a chronic disease for which patients require lifetime management; long‐term safety data are important to understand the benefits and risks of prolonged treatment.Here, 3‐year data from a pooled analysis of three phase III trials of certolizumab pegol in plaque psoriasis are presented, representing 2231·3 patient‐years of exposure.No new safety signals were identified and the risk of treatment‐emergent adverse events did not increase with longer or higher certolizumab pegol exposure.

Importance Treatments for psoriasis may be less effective in everyday practice than in clinical trials. Emulating a target trial using data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) can provide treatment effect estimates that are robust and can inform both clinicians and regulatory bodies. Objectives To assess the comparative effectiveness of ustekinumab and secukinumab in patients with psoriasis, and to test whether the relative effectiveness estimate of the CLEAR trial, a randomized clinical trial that compared secukinumab with ustekinumab for psoriasis, can be replicated. Design, Setting, and Participants This comparative effectiveness research study used a target trial emulation approach and was performed between November 2007 and August 2019. Data were obtained from BADBIR, a multicenter longitudinal pharmacovigilance register of patients with moderate to severe psoriasis in the United Kingdom and Republic of Ireland. Participants had chronic plaque psoriasis, were 18 years or older, and had at least 1 record of a Psoriasis Area and Severity Index (PASI) of 12 or higher before their initiation to secukinumab or ustekinumab. Propensity score (PS) 1:1 matched analysis and inverse probability treatment weighted analysis were performed. Main Outcomes and Measures The primary outcomes were the risk ratio (RR) and the risk difference (RD) for achieving PASI of 2 or lower after 12 months of therapy for secukinumab compared with ustekinumab. Methods to account for missing outcome data were complete case analysis, nonresponder imputation, last observation carried forward, inverse probability of censoring weighting, and multiple imputation. Regulatory and estimate agreement metrics were used to benchmark the effect estimates in this study against those in the CLEAR trial. Results A total of 1231 patients were included in the analysis, with 917 receiving ustekinumab and 314 receiving secukinumab. Secukinumab was superior to ustekinumab in all analyses, except under the nonresponder imputation method, in the proportion of participants achieving a PASI of 2 or lower (PS-weighted complete case analysis: RR, 1.28 [95% CI, 1.06-1.55]; RD, 11.9% [1.6-22.1]). All analyses, except for nonresponder imputation, reached regulatory agreement in both PS-matching and PS-weighted analyses. Conclusions and Relevance This comparative effectiveness study found that secukinumab resulted in more patients achieving a PASI of 2 or lower after 12 months of therapy compared with ustekinumab in patients with psoriasis. Target trial emulation in this study resulted in regulatory and estimate agreement with the CLEAR randomized clinical trial; further such studies may help fill the evidence gap when comparing other systemic therapies for psoriasis.

Many governments around the world have enforced social distancing strategies in an effort to prevent the spread of the novel coronavirus, termed SARS-Co-V-2, which can lead to a fatal respiratory disease known as coronavirus disease 2019 (COVID-19). On 22nd March 2020 the UK government announced that over 1.5 million "extremely vulnerable" adults (those likely to suffer from more severe symptoms of COVID-19, such as age over 70, significant comorbidities or concurrent immunosuppression) would have to take additional measures and shield1 .

ObjectivesRegistry data suggest that people with immune-mediated inflammatory diseases (IMIDs) receiving targeted systemic therapies have fewer adverse COVID-19 outcomes compared to patients receiving no systemic treatments. We used international patient survey data to explore the hypothesis that greater risk-mitigating behaviour in those receiving targeted therapies may account, at least in part, for this observation.MethodsOnline surveys were completed by individuals with Rheumatic and Musculoskeletal Diseases (RMD) (UK only) or psoriasis (globally) between 4th May and 7th September 2020. We used multiple logistic regression to assess the association between treatment type and risk-mitigating behaviour, adjusting for clinical and demographic characteristics. We characterised international variation in a mixed effects model.ResultsOf 3,720 participants (2,869 psoriasis, 851 RMD) from 74 countries, 2,262 (60.8%) reported the most stringent risk-mitigating behaviour (classified here under the umbrella term ‘shielding’). A greater proportion of those receiving targeted therapies (biologics and JAK inhibitors) reported shielding compared to those receiving no systemic therapy (adjusted odds ratio [OR] 1.63, 95% CI 1.35-1.97) and standard systemic agents (OR 1.39, 95% CI 1.22-1.56). Shielding was associated with established risk factors for severe COVID-19 (male sex [OR 1.14, 95% CI 1.05-1.24], obesity [OR 1.38, 95% CI 1.23-1.54], comorbidity burden [OR 1.43, 95% CI 1.15-1.78]), a primary indication of RMD (OR 1.37, 95% CI 1.27-1.48) and a positive anxiety or depression screen (OR 1.57, 95% CI 1.36-1.80). Modest differences in the proportion shielding were observed across nations.ConclusionsGreater risk-mitigating behaviour among people with IMIDs receiving targeted therapies may contribute to the reported lower risk of adverse COVID-19 outcomes. The behaviour variation across treatment groups, IMIDs and nations reinforces the need for clear evidence-based patient communication on risk mitigation strategies and may help inform updated public health guidelines as the pandemic continues.Key messagesWhat is already known about this subject?At the beginning of the COVID-19 pandemic, patients with immune mediated inflammatory diseases (IMIDs) on targeted systemic immunosuppressive therapy were considered to be at higher risk of severe COVID-19. Subsequent registry data suggest that this may not the case.What does this study add?Here we characterise shielding behaviour in patients with IMIDs from a global survey. We identified that targeted systemic therapy associates with increased shielding behaviour, as do demographic risk factors for severe COVID-19 including male gender and obesity.Shielding behaviour varies across nations, albeit modestly when case-mix is taken into account.How might this impact on clinical practice or future developments?Variable shielding behaviour amongst patients with IMIDs may be an important confounder when considering differential COVID-19 risk between therapy types, so should be accounted for in analyses where possible.

Introduction Dupilumab is a biologic therapy approved for treatment of moderate to severe atopic dermatitis (AD). Our objective was to assess the real-world effectiveness, safety and laboratory monitoring practices for dupilumab in a tertiary centre. Methods A retrospective review of medical records of all patients receiving dupilumab between September 2017 and October 2019 was undertaken. Eczema Area and Severity Index (EASI) and Dermatology Life Quality Index (DLQI) were collected at weeks 0, 12–16 and 26–30. Data on laboratory tests undertaken for dupilumab screening and monitoring were also collected. Results At 12–16 weeks, 58.9% and 37.3% of patients achieved ≥ EASI 75 and ≥ EASI 90, respectively (n = 156). Ninety-four patients underwent further analysis at weeks 26–30 with those achieving ≥ EASI 75 increasing from 61.7% (12–16 weeks) to 75.31%, and EASI 90 increasing from 35.8% (12–16 weeks) to 49.8%. The most common side effects were eye symptoms occurring in 43.1% of patients, with 16.3% developing conjunctivitis. The mean treatment duration was 255 days, during which an average of three sets of blood tests were performed (n = 149). Of all laboratory abnormalities recorded, 24% started after initiation of dupilumab, and 93% were classified as ‘mild’. Dupilumab was not documented as causative in any of the cases, nor was treatment stopped on account of laboratory abnormalities. Conclusion Dupilumab provides an effective and safe treatment option for patients with AD. Clinical response continued to improve past 16 weeks in this real-world population. No laboratory abnormalities were felt to be secondary to dupilumab; screening and monitoring tests did not influence dupilumab prescribing.

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., Video abstract

Background As treatment interruptions occur during psoriasis management in clinical practice, it is important to know the duration of clinical response after treatment withdrawal. Objectives To report time to and predictors of relapse in patients who were tildrakizumab 100 and 200 mg responders (≥75% improvement in Psoriasis Area and Severity Index, PASI 75) at week 28 re‐randomized to placebo from reSURFACE 1 trial. Methods Post hoc analysis of adult patients with moderate‐to‐severe plaque psoriasis from a 64‐week phase 3 trial. Relapse was primarily defined as loss of PASI 75 response. Both relapses defined as loss of PASI 90 and loss of absolute PASI < 2 response were included as sensitivity analyses. PASI 75, PASI 90 and PASI < 2 responders re‐randomized to placebo at week 28 and followed up until week 64 were included. The Kaplan–Meier (KM) estimates of the 64‐week relapse rate were calculated. The log‐rank test to compare KM curves from responders to tildrakizumab 100 and 200 mg was used. Independent predictors of relapse were explored. Results Median time to loss of PASI 75/PASI 90/PASI < 2 response from week 28 was 142/111/112 days with tildrakizumab 100 mg and 172/140/113 days with tildrakizumab 200 mg, respectively (all not significant). Around 20% of patients did not relapse (either maintained a PASI 75 response or were lost to follow‐up) during the 36‐week period. Increase in body mass index (BMI) (hazard ratio, HR [95% confidence interval, CI] for loss of PASI 75 response: 1.0345 [1.0112–1.0582]) and increase in disease duration (HR [95% CI]: 1.0151 [1.0028–1.0275] for loss of PASI 75 response) were associated with an increased risk of relapse, regardless of the relapse definition. Conclusions When treatment is interrupted, tildrakizumab provides durable maintenance of efficacy with a median time to loss of PASI 75 response of 5–6 months, irrespective of the dose. Interventions on modifiable risk factors for relapse, such as BMI, may improve personalized long‐term psoriasis management.

Introduction A range of treatments are available for moderate-to-severe psoriasis; however, there remains a paucity of direct comparisons of these in head-to-head trials. Network meta-analyses (NMA) allow comparisons of these to support clinical decision making. This systematic literature review assesses the methodological quality of NMAs available for moderate-to-severe psoriasis and compares their methods and results. Their validity and applicability for current practice is also assessed. Methods A systematic review of published NMAs of at least two biologics for moderate-to-severe psoriasis was undertaken. Embase, MEDLINE, MEDLINE In-Process, and the Cochrane Library were last searched on 19 February 2020. The quality of NMAs was assessed using the International Society of Pharmacoeconomics and Outcomes Research (ISPOR) criteria. NMA methodology, funding, and results were compared and differences in results explored. Results Twenty-five analyses evaluating up to 19 different treatments at 8–24 weeks, and two analyses at 1 year, were included. Psoriasis Area Severity Index (PASI) response was assessed in 23, facilitating comparisons between NMAs. All NMAs met at least half of the ISPOR criteria. The major limitations were explaining the rationale for methodology, exploring effect modifiers, and consistency between direct and indirect estimates. The analyses differed in model type (Bayesian or frequentist), analysis of PASI response (binomial or multinomial), and analysis of different treatment doses (separate or pooled). PASI results were broadly similar, except for the Cochrane Collaboration NMA which provided lower estimates of treatment efficacy versus placebo. This analysis differed methodologically from others, including pooling data for different doses. Conclusions Based on PASI 90 at induction, the majority of recent NMAs came to similar conclusions: interleukin (IL) 17 inhibitors (brodalumab, ixekizumab, secukinumab), IL-23 inhibitors (guselkumab and risankizumab) and infliximab were most efficacious, supporting the validity of NMAs in this clinical area. Decisions should be made using high-quality, up-to-date NMAs with assumptions relevant to clinical practice.

The therapeutic landscape for psoriasis is ever-changing. Risankizumab is the newest approved biologic and one of three currently licensed that targets the p19 subunit of interleukin-23 (IL-23). It is increasingly clear that different biologics vary in their efficacy, effectiveness, and safety profiles, highlighting that there is a need to understand for which patients and in which circumstances to use each drug.This article summarizes original clinical trial data, and reviews in more detail recent post-marketing studies and meta-analyses that differentiate risankizumab from other biologics. It also briefly explores the evidence for risankizumab in the treatment of other immune-mediated inflammatory diseases.Risankizumab is a highly effective biologic for the treatment of moderate-to-severe plaque psoriasis. Recent open-label extension data for risankizumab shows sustained treatment responses to week 136. Indirect comparisons suggest IL-17 inhibitors have a faster onset, though head-to-head comparison with secukinumab shows non-inferiority at week 16 and superiority of risankizumab at week 52. Risankizumab is very well tolerated and data from the IMMhance trial suggests that risankizumab can be used in patients with latent tuberculosis without risk of reactivation.

Key Points Question Are clinical and demographic factors associated with the severity of palmoplantar pustulosis? Findings In a cross-sectional study of 203 patients in the UK, the Palmoplantar Pustulosis Psoriasis Area Severity Index score was significantly higher in women compared with men and in current smokers vs former and never smokers. Both of these findings were replicated in an independently ascertained, Northern European cohort including 159 patients. Meaning The findings of this study suggest that smoking cessation interventions may be beneficial in patients with palmoplantar pustulosis and should be investigated in clinical studies., Importance Although palmoplantar pustulosis (PPP) can significantly impact quality of life, the factors underlying disease severity have not been studied. Objective To examine the factors associated with PPP severity. Design, Setting, and Participants An observational, cross-sectional study of 2 cohorts was conducted. A UK data set including 203 patients was obtained through the Anakinra in Pustular Psoriasis, Response in a Controlled Trial (2016-2019) and its sister research study Pustular Psoriasis, Elucidating Underlying Mechanisms (2016-2020). A Northern European cohort including 193 patients was independently ascertained by the European Rare and Severe Psoriasis Expert Network (2014-2017). Patients had been recruited in secondary or tertiary dermatology referral centers. All patients were of European descent. The PPP diagnosis was established by dermatologists, based on clinical examination and/or published consensus criteria. The present study was conducted from October 1, 2014, to March 15, 2020. Main Outcomes and Measures Demographic characteristics, comorbidities, smoking status, Palmoplantar Pustulosis Psoriasis Area Severity Index (PPPASI), measuring severity from 0 (no sign of disease) to 72 (very severe disease), or Physician Global Assessment (PGA), measuring severity as 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), and 4 (severe). Results Among the 203 UK patients (43 men [21%], 160 women [79%]; median age at onset, 48 [interquartile range (IQR), 38-59] years), the PPPASI was inversely correlated with age of onset (r = −0.18, P = .01). Similarly, in the 159 Northern European patients who were eligible for inclusion in this analysis (25 men [16%], 134 women [84%]; median age at onset, 45 [IQR, 34-53.3] years), the median age at onset was lower in individuals with a moderate to severe PGA score (41 years [IQR, 30.5-52 years]) compared with those with a clear to mild PGA score (46.5 years [IQR, 35-55 years]) (P = .04). In the UK sample, the median PPPASI score was higher in women (9.6 [IQR, 3.0-16.2]) vs men (4.0 [IQR, 1.0-11.7]) (P = .01). Likewise, moderate to severe PPP was more prevalent among Northern European women (57 of 134 [43%]) compared with men (5 of 25 [20%]) (P = .03). In the UK cohort, the median PPPASI score was increased in current smokers (10.7 [IQR, 4.2-17.5]) compared with former smokers (7 [IQR, 2.0-14.4]) and nonsmokers (2.2 [IQR, 1-6]) (P = .003). Comparable differences were observed in the Northern European data set, as the prevalence of moderate to severe PPP was higher in former and current smokers (51 of 130 [39%]) compared with nonsmokers (6 of 24 [25%]) (P = .14). Conclusions and Relevance The findings of this study suggest that PPP severity is associated with early-onset disease, female sex, and smoking status. Thus, smoking cessation intervention might be beneficial., This cross-sectional study examines factors that may contribute to the severity of symptoms in patients with palmoplantar pustulosis.

We wish to bring your attention to the PsoPROTECT (Psoriasis Patient Registry for Outcomes, Therapy and Epidemiology of Covid‐19 infecTion) and SECURE‐AD (Surveillance Epidemiology of Coronavirus Under Research Exclusion‐Atopic Dermatitis) registries; two urgent global initiatives that address an unmet need for delineating the determinants of COVID‐19 outcomes in the common cutaneous immune‐mediated inflammatory diseases (IMIDs) psoriasis and atopic dermatitis.

Topical psoriasis treatment relies on a reactive rather than a long-term proactive approach to disease relapse.Assess long-term efficacy and safety of proactive psoriasis management with twice-weekly calcipotriene 0.005%/betamethasone dipropionate 0.064% (Cal/BD) foam.Phase III trial (NCT02899962) included a 4-week open-label lead-in phase (Cal/BD foam once daily) and a 52-week, randomized, double-blind, maintenance phase. A total of 545 patients achieved treatment success (physician's global assessment "clear"/"almost clear," ≥2-grade improvement from baseline) and were randomized to proactive management (Cal/BD foam; n = 272) or reactive management (vehicle foam; n = 273) twice-weekly, with rescue treatment of Cal/BD foam once daily for 4 weeks upon relapse. Primary endpoint was time to first relapse (physician's global assessment "mild" or higher).A total of 251 randomized patients (46.1%) completed the trial. Median time to first relapse was 56 days (proactive) and 30 days (reactive). Patients in the proactive group had an additional 41 days in remission compared with the reactive group over 1 year (P .001). Number of relapses per year of exposure was 3.1 (proactive) and 4.8 (reactive). Cal/BD foam was well tolerated.Maintenance phase dropout rate (53.9%) was within the expected range but provides challenges in statistical analysis.Long-term proactive management with Cal/BD foam demonstrated superior efficacy vs reactive management.

BackgroundPsoriasis is associated with risk factors for serious infections, but the independent relationship between psoriasis and serious infection is as yet unclear.ObjectivesTo determine whether people with psoriasis have a higher risk of hospitalization due to any infection, respiratory infections, soft‐tissue and skin infections, or a higher risk of death due to infection.MethodsWe conducted a cohort study of people (≥ 18 years) with psoriasis using the UK Clinical Practice Research Datalink (CPRD GOLD) linked to Hospital Episode Statistics (HES) and Office for National Statistics (ONS) mortality records between 1 April 2003 and 31 December 2016, and matched with up to six comparators on age, sex and general practice. Hospitalization was ascertained from HES records; death was ascertained from ONS mortality records. Stratified Cox proportional hazard models were estimated, with stepwise adjustment in different models for potential confounders or mediators between psoriasis and serious infection.ResultsThere were 69 315 people with psoriasis and 338 620 comparators who were followed up for a median (interquartile range) of 4·9 (5·9) and 5·1 (6·3) years, respectively. People with psoriasis had a higher incidence rate of serious infection [20·5 per 1000 person‐years, 95% confidence interval (CI) 20·0–21·0, n = 7631] compared with those without psoriasis (16·1 per 1000 person‐years, 95% CI 15·9–16·3, n = 30 761). The fully adjusted hazard ratio for the association between psoriasis and serious infection was 1·36 (95% CI 1·31–1·40), with similar results across the other outcomes.ConclusionsPsoriasis is associated with a small increase in the risk of serious infection. Further research is needed to understand how psoriasis predisposes to a higher risk of infection.

BACKGROUND: Real-world biologic drug survival is an important proxy measure for effectiveness. Predictors of drug survival may help patients with psoriasis choose between biologic therapies.\ud \ud OBJECTIVES: (i) To assess the relative drug survival of adalimumab, ustekinumab and secukinumab in patients with psoriasis. (ii) To investigate predictors of biologic drug survival. \ud \ud METHODS: A prospective cohort study was performed in the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) between November 2007 and August 2019. We performed survival analysis and fitted a flexible parametric survival model for biologic discontinuation due to ineffectiveness. \ud \ud RESULTS: In total 9652 patients were included: 5543 starting on adalimumab (57·4%), 991 on secukinumab (10·3%) and 3118 on ustekinumab (32·3%). The overall drug survivals of adalimumab, secukinumab and ustekinumab in year 1 were 0·78 [95% confidence interval (CI) 0·77-0·79], 0·88 (95% CI 0·86-0·91) and 0·88 (95% CI 0·87-0·89), respectively. The adjusted hazard ratios (adjHRs) for discontinuation of adalimumab and secukinumab compared with ustekinumab were 2·11 (95% CI 1·76-2·54) and 0·67 (95% CI 0·40-1·11), respectively. The presence of psoriatic arthritis predicted for survival in the adalimumab and secukinumab cohorts (adjHR 0·67, 95% CI 0·51-0·88 and 0·70, 95% CI 0·40-1·24, respectively), but for discontinuation in the ustekinumab cohort (adjHR 1·42, 95% CI 1·12-1·81). Previous exposure to biologic therapies predicted for discontinuation in the ustekinumab and secukinumab cohorts (adjHR 1·54, 95% CI 1·26-1·89 and 1·49, 95% CI 0·91-2·45, respectively) and for survival in the adalimumab cohort (adjHR 0·71, 95% CI 0·55-0·92). \ud \ud CONCLUSIONS: Secukinumab and ustekinumab have similar sustained drug survival, while adalimumab has a lower drug survival in patients with psoriasis. Psoriatic arthritis and previous biologic experience were predictors with differential effects between the biologic therapies. What is already known about this topic? There is conflicting evidence over the real-world drug survival of secukinumab in patients with psoriasis. Data from registries to date suggest that secukinumab has a lower drug survival than that reported from clinical trials. What does this study add? This study found that secukinumab and ustekinumab had similar sustained drug survival in the real world, while the drug survival of adalimumab was lower, suggesting that the real-world drug survival of secukinumab is higher than previously reported. We found that psoriatic arthritis and previous biologic experience had differential effects on drug discontinuation in the three biologic cohorts. These predictors may help patients and clinicians choose the most appropriate biologic therapy.

Background Adalimumab (Humira® , AbbVie Inc., North Chicago, IL, U.S.A.) is a fully human monoclonal antibody specific for tumour necrosis factor-α that is approved to treat adults with moderate-to-severe chronic plaque psoriasis. Objectives To assess long-term safety for patients with psoriasis receiving adalimumab in clinical studies. Methods Adalimumab safety data from adults with psoriasis who received at least one adalimumab dose in 18 clinical trials were evaluated. Adalimumab was delivered subcutaneously in all treatment regimens. Treatment-emergent adverse events (AEs) were collected from the first dose to 70 days after the last dose or cut-off date (31 December 2015). AE incidence rates were expressed as events per 100 patient-years (E/100 PYs) of adalimumab exposure. Standardized incidence ratios (SIRs) for malignancies and standardized mortality ratios (SMRs) were calculated. Results Cumulative exposure was 5429·7 PYs in 3727 patients. Overall, there were 16 536 AEs (304·6 E/100 PYs). The most common AEs were nasopharyngitis, upper respiratory infection and headache (23·7, 12·9 and 7·9 E/100 PYs, respectively). Incidence rates for serious infections, tuberculosis and opportunistic infections were 1·8, 0·3 and 0·02 E/100 PYs, respectively. Incidence of malignancy excluding nonmelanoma skin cancer (NMSC) was 0·8 E/100 PYs [SIR 0·86, 95% confidence interval (CI) 0·58-1·23]. Incidences of NMSC and melanoma were 0·6 and 0·2 E/100 PYs, respectively. The SIR was 1·55 (95% CI 1·10-2·13) for NMSC and 3·04 (95% CI 1·11-6·62) for melanoma. The SMR was 0·34 (95% CI 0·16-0·65). Conclusions AE rates remained stable in this analysis of patients with psoriasis receiving adalimumab; no new safety signals were identified compared with earlier analyses.

Ustekinumab is an interleukin-12/23 inhibitor used for the treatment of moderate-to-severe psoriasis. Here, we review new evidence since ustekinumab was licensed for relative efficacy in comparison with other biologic therapies from head-to-head randomized controlled trials and network meta-analyses for the treatment of psoriasis. We also review observational data emerging from psoriasis registries reporting the effectiveness and safety of ustekinumab. Overall, new evidence suggests that ustekinumab has a favorable balance between efficacy/effectiveness, safety, and tolerability and should remain a first-line biologic therapy option for patients with severe psoriasis at present.

BACKGROUND: Psoriasis causes work productivity impairment that increases with disease severity. Whether differential treatment efficacy translates into differential indirect cost savings is unknown.OBJECTIVE: To assess work hours lost and indirect costs associated with secukinumab versus ustekinumab and etanercept in the United Kingdom (UK).METHODS: This was a post hoc analysis of work impairment data collected in the CLEAR study (secukinumab vs. ustekinumab) and applied to the FIXTURE study (secukinumab vs. etanercept). Weighted weekly and annual average indirect costs per patient per treatment were calculated from (i) overall work impairment derived from Work Productivity and Activity Impairment data collected in CLEAR at 16 and 52 weeks by Psoriasis Area and Severity Index (PASI) response level; (ii) weekly/annual work productivity loss by PASI response level; (iii) weekly and annual indirect costs by PASI response level, based on hours of work productivity loss; and (iv) weighted average indirect costs for each treatment. In the primary analysis, work impairment data for employed patients in CLEAR at Week 16 were used to compare secukinumab and ustekinumab. Secondary analyses were conducted at different time points and with patient cohorts, including FIXTURE.RESULTS: In CLEAR, 452 patients (67%) were employed at baseline. At Week 16, percentages of weekly work impairment/mean hours lost decreased with higher PASI: PASI < 50: 22.8%/7.60 h; PASI 50-74: 13.3%/4.45 h; PASI 75-89: 6.4%/2.14 h; PASI ≥ 90: 4.9%/1.65 h. Weighted mean weekly/annual work hours lost were significantly lower for secukinumab than ustekinumab (1.96/102.51 vs. 2.40/125.12; P = 0.0006). Results were consistent for secukinumab versus etanercept (2.29/119.67 vs. 3.59/187.17; ΡCONCLUSIONS: Secukinumab significantly reduced work impairment and associated indirect costs of psoriasis compared with ustekinumab and etanercept at Week 16 through 52 in the United Kingdom.

BACKGROUND: Head-to-head randomised studies comparing ixekizumab and secukinumab in the treatment of psoriasis are not available.OBJECTIVE: Assess efficacy and quality of life with ixekizumab vs. secukinumab treatment using matching-adjusted indirect comparisons.METHODS: Psoriasis Area and Severity Index (PASI) improvement of at least 75%, 90% and 100% and Dermatology Life Quality Index (DLQI) 0/1 response rates for approved doses of ixekizumab (160 mg at Week 0, then 80 mg every two weeks for the first 12 weeks) and secukinumab (300 mg at Weeks 0, 1, 2, 3 and 4, then 300 mg every 4 weeks) treatment were compared using data from active (etanercept and ustekinumab) and placebo-controlled studies. Comparisons were made using the Bucher (BU) and two modified versions of the Signorovitch method (SG total and SG separate). Subsequently, results based on active treatment common comparators were combined using generic inverse-variance meta-analysis.RESULTS: In meta-analysis of studies with active comparators, PASI 90 response rates were 12.7% (95% CI: 5.5%-19.8%; p=0.0005), 10.0% (2.1%-18.0%; p=0.01) and 11.2% (3.2%-19.1%; p=0.006) higher and PASI 100 response rates 11.7% (5.9%-17.5%; pCONCLUSION: Ixekizumab had higher PASI 90 and PASI 100 responses at Week 12 compared to secukinumab using adjusted indirect comparisons.
