Background: Certolizumab pegol (CZP) is an Fc‐free, PEGylated anti‐tumor necrosis factor biologic. Objectives: To report 3‐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 mg 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. [ABSTRACT FROM AUTHOR]

Background: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin-17A and interleukin-17F. The efficacy and safety of bimekizumab as compared with the tumor necrosis factor inhibitor adalimumab in patients with moderate-to-severe plaque psoriasis have not been extensively examined.Methods: We randomly assigned patients with moderate-to-severe plaque psoriasis in a 1:1:1 ratio to receive subcutaneous bimekizumab at a dose of 320 mg every 4 weeks for 56 weeks; bimekizumab at a dose of 320 mg every 4 weeks for 16 weeks, then every 8 weeks for weeks 16 to 56; or subcutaneous adalimumab at a dose of 40 mg every 2 weeks for 24 weeks, followed by bimekizumab at a dose of 320 mg every 4 weeks to week 56. The primary end points were a 90% or greater reduction from baseline in the Psoriasis Area and Severity Index (PASI) score (PASI 90 response; PASI scores range from 0 to 72, with higher scores indicating worse disease) and an Investigator's Global Assessment (IGA) score of 0 or 1, signifying clear or almost clear skin (scores range from 0 [clear skin] to 4 [severe disease]), at week 16. The analysis of the primary end points tested noninferiority at a margin of -10 percentage points and then tested for superiority.Results: A total of 614 patients were screened, and 478 were enrolled; 158 patients were assigned to receive bimekizumab every 4 weeks, 161 to receive bimekizumab every 4 weeks and then every 8 weeks, and 159 to receive adalimumab. The mean age of the patients was 44.9 years; the mean PASI score at baseline was 19.8. At week 16, a total of 275 of 319 patients (86.2%) who received bimekizumab (both dose groups combined) and 75 of 159 (47.2%) who received adalimumab had a PASI 90 response (adjusted risk difference, 39.3 percentage points; 95% confidence interval [CI], 30.9 to 47.7; P<0.001 for noninferiority and superiority). A total of 272 of 319 patients (85.3%) who received bimekizumab and 91 of 159 (57.2%) who received adalimumab had an IGA score of 0 or 1 (adjusted risk difference, 28.2 percentage points; 95% CI, 19.7 to 36.7; P<0.001 for noninferiority and superiority). The most common adverse events with bimekizumab were upper respiratory tract infections, oral candidiasis (predominantly mild or moderate as recorded by the investigator), hypertension, and diarrhea.Conclusions: In this 56-week trial, bimekizumab was noninferior and superior to adalimumab through 16 weeks in reducing symptoms and signs of plaque psoriasis but was associated with a higher frequency of oral candidiasis and diarrhea. Longer and larger trials are required to determine the efficacy and safety of bimekizumab as compared with other agents in the treatment of plaque psoriasis.

Abstract: Fumaric acid esters (FAEs) are a group of small molecules that were first investigated for the treatment of psoriasis in 1959. The first fumarate‐based drug – Fumaderm® – was approved in Germany in 1994 for severe psoriasis and then in 2008, the label was expanded to include moderate psoriasis. Fumaderm is a combination of different FAEs: dimethyl fumarate (DMF), which is regarded as the main active component, plus calcium, magnesium and zinc salts of monoethyl fumarate (MEF). FAEs are the most frequently used first‐line systemic psoriasis treatment in Germany, with an overall treatment experience comprising more than 220 000 patient‐years. FAEs have demonstrated good, sustained clinical efficacy with an acceptable safety profile for the long‐term treatment of patients with moderate‐to‐severe psoriasis. Indeed, the European S3‐Guideline on the systemic treatment of Psoriasis vulgaris recommends FAEs for induction and long‐term treatment. Until recently, FAEs were only licensed (for the psoriasis indication) in Germany, but were imported to many other European countries, such as The Netherlands, UK, Ireland, Austria and Italy, for the treatment of psoriasis. In 2017, the European Medicines Agency (EMA) approved Skilarence®, a new oral formulation of DMF, for the treatment of adult patients with moderate‐to‐severe chronic plaque psoriasis in need of systemic therapy. Skilarence only contains DMF and is the first FAE for the treatment of psoriasis that has been approved by the EMA. This approval has given rise to a new oral treatment option for patients with moderate‐to‐severe plaque psoriasis across Europe. Here, we report the results of an expert meeting which was convened to deliver clinician‐agreed consensus and real‐world guidance on the clinical use of DMF in moderate‐to‐severe chronic plaque psoriasis. Guidance on appropriate patient selection, DMF dosage considerations, monitoring and side‐effect management is offered based upon available evidence and collective real‐world clinical experience.

Summary: This review provides a summary of key findings from 27 systematic reviews of 51 articles first published or indexed during 2015, focusing on the treatment of psoriasis and on precision medicine in psoriasis. The evidence supports weight‐loss interventions by dieting and exercise for improvement in disease severity in overweight and obese patients with psoriasis. No significant increased risk of serious infections was reported for the biologic therapies adalimumab, etanercept and ustekinumab compared with appropriate comparators. Evidence could not provide reliable estimates of rare adverse events, emphasizing the need for large prospective registries. Polymorphisms in the tumour necrosis factor (TNF)‐α gene may confer improved responses to TNF inhibitor (TNFI) therapy, but the studies to date lack power to detect a true association. From the limited available evidence, multidisciplinary management is both more effective and more satisfactory for patients with psoriasis and psoriatic arthritis than conventional consultations. This summary of reviews provides a succinct guide for clinicians and patients wishing to remain up to date with high‐quality evidence for the treatment of psoriasis. [ABSTRACT FROM AUTHOR]

Abstract: Background: Many patients with psoriasis have undiagnosed psoriatic arthritis. Low specificity is found with many PsA screening tools. A new instrument, the CONTEST questionnaire, was developed utilizing the most discriminative items from existing instruments. Objective: The aim of this study was to compare the CONTEST and PEST screening tools. Methods: People attending secondary care clinics with psoriasis, but not PsA, completed the questionnaires, were assessed for function and quality of life, and had a physical examination. Patients thought to have PsA were compared to those without. The performance of CONTEST and PEST was compared using area under the receiver operating curve (AUC), and sensitivity and specificity at the previously published cut‐offs. Results: A total of 451 dermatology patients were approached, 35% were reviewed and 27 (17%, 95% CI 12.3–21.7) had unidentified psoriatic arthritis. The sensitivity and specificity (95% CI) of PEST were 0.60 (0.42–0.78)/0.76 (0.69–0.83) and for CONTEST 0.53 (0.34–0.72)/0.71 (0.63–0.79). The confidence limits for the AUC overlapped (AUC for PEST 0.72 (0.61–0.84), for CONTEST 0.66 (0.54–0.77). Conclusions: PEST and CONTEST questionnaires performed equally well, with no superiority of the new CONTEST tool. [ABSTRACT FROM AUTHOR]

Summary: Background: Head‐to‐head randomized studies comparing ixekizumab and secukinumab in the treatment of psoriasis are not available. Objectives: To assess efficacy and quality of life using matching‐adjusted indirect comparisons for treatment with ixekizumab vs. secukinumab. 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 dosages 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) method and two modified versions of the Signorovitch (SG) method (SG total and SG separate). Subsequently, results based on active treatment common comparators were combined using generic inverse‐variance meta‐analysis. Results: In the meta‐analysis of studies with active comparators, PASI 90 response rates were 12·7% [95% confidence interval (CI) 5·5–19·8, P = 0·0005], 10·0% (95% CI 2·1–18·0, P = 0·01) and 11·2% (95% CI 3·2–19·1, P = 0·006) higher and PASI 100 response rates were 11·7% (95% CI 5·9–17·5, P < 0·001), 12·7% (95% CI 6·0–19·4, P < 0·001) and 13·1% (95% CI 6·3–19·9, P < 0·001) higher for ixekizumab compared with secukinumab using BU, SG total and SG separate methods. PASI 75 results were comparable when SG methods were used and favoured ixekizumab when the BU method was used. Week 12 DLQI 0/1 response rates did not differ significantly. Conclusions: Ixekizumab had higher PASI 90 and PASI 100 responses at week 12 compared with secukinumab using adjusted indirect comparisons. [ABSTRACT FROM AUTHOR]

An evaluation of dermatology patients shielding during the COVID-19 outbreak Retrospective analysis of patient records/pharmacy lists revealed 1071 patients that met the British Association of Dermatologists' criteria for shielding.4 Printed letters were posted to these patients, advising them accordingly. In conclusion, the majority of our highly vulnerable dermatology patients shielded, continued to take their immunosuppressive medication and denied any symptoms of COVID-19.

Experts in psoriasis, hepatology, pharmacokinetics and pharmacogenetics convened to discuss the safety and monitoring of methotrexate with respect to hepatotoxicity when used in the treatment of psoriasis. Methotrexate is an efficacious and cost-effective treatment for psoriasis, but is associated with significant safety issues, particularly relating to hepatotoxicity. Current British, Dutch, German, EU and US guidelines for baseline evaluations, monitoring and prevention of hepatotoxicity in patients with psoriasis receiving methotrexate were evaluated. Liver safety monitoring is currently reliant upon multiple methods, including biopsy, serological tests for biomarkers such as type III procollagen amino terminal propeptide (PIIINP), and liver function tests based on liver enzymes. Monitoring of patients receiving long-term therapy is expected to be improved by the utilization of serum biomarkers currently in development such as the Enhanced Liver Fibrosis (ELF) panel and other non-invasive tests of hepatic architecture, such as fibroelastography, microbubbles and magnetic resonance imaging. Appropriate studies to determine optimal dosing to maximize efficacy and minimize toxicity, potentially utilizing pharmacogenetic principles, are clearly needed. Key questions for future research are identified including needs for optimal screening and monitoring, identification of appropriate biomarkers, assessment of relationships between dosing and safety, utility of liver biopsy, optimal dosing regimens (including route of administration), methods to measure methotrexate levels in blood, and use of methotrexate as a standardized active comparator in trials of experimental drugs used to treat psoriasis.

Tuberculosis (TB), caused by Mycobacterium tuberculosis, is a significant global health problem. In immunocompetent individuals, the microorganism can remain in a latent, non‐contagious form, however, it may become active under conditions of immunosuppression. Tumour necrosis factor (TNF) inhibitors, which are frequently used for the management of immune‐mediated disorders like psoriasis, have been associated with a significantly increased risk of reactivating latent TB. Consequently, international guidelines recommend TB screening and preventive treatment before starting anti‐TNF therapy. These recommendations have extended to IL‐12/23, IL‐17, IL‐23 and TYK2 inhibitors under a caution principle, despite their different mechanisms of action. However, current evidence suggests that some of these agents are arguably not associated with an increased risk of TB reactivation or development of TB disease after infection, which calls for a critical reassessment of these guidelines. We have conducted a literature search evaluating the risk of TB reactivation associated with these innovative therapies, integrating findings from both randomized clinical trials and real‐world evidence. The identified evidence is limited but the low number of identified cases of reactivation with IL‐17 and IL‐23 inhibitors prompts reconsidering the need for preventive treatment for latent TB in all cases, regardless of biologic class or individual patient's risk of TB reactivation or drug toxicity. This review, along with the clinical insight of a panel of experts on behalf of the SPIN‐FRT, led to the development of these consensus recommendations for managing psoriasis treatment in patients with latent TB infection or at risk of TB infection, who are receiving or are intended to receive biologic and non‐biologic targeted therapies. These recommendations highlight the need for updates to the existing guidelines, aiming to provide a more differentiated approach that reflects the evolving landscape of psoriasis treatment and its implications for TB management.
