Clinical Goals and Barriers to Effective Psoriasis Care

High Systemic Disease Risk and Therapeutic Delays in Plaque Psoriasis: A Retrospective Analysis of Apremilast Use in the British Association of Dermatologists Biologic and Immunomodulators Register (BADBIR)

INTRODUCTION

We describe comorbidities and cardiovascular diseases (CVD) risk in patients with psoriasis prescribed apremilast in UK clinical practice. Such real-world data are currently sparse.

METHODS

This observational, retrospective analysis of British Association of Dermatologists Biologic and Immunomodulators Register (BADBIR) included adults with plaque psoriasis first prescribed apremilast between October 2015 and March 2021. We evaluated patient comorbidities, 10-year CVD risk (Framingham risk score), time from psoriasis diagnosis, prior therapy, psoriasis severity and patient-reported quality of life (QoL) at first apremilast prescription or registry enrolment. Patient characteristics were also assessed by CVD risk and Fitzpatrick skin type.

RESULTS

Of 265 eligible patients, 47.5% were female; median (Q1, Q3) age at first apremilast prescription was 50 (38, 60) years. The most common comorbidities were hypertension (23.4%), depression (21.5%), psoriatic arthritis (18.1%) and diabetes (15.8%). Median (Q1, Q3) time from psoriasis diagnosis to first apremilast prescription was 19 (11, 30) years; median (Q1, Q3) number of prior psoriasis therapies was 1 (1, 2). Most patients had a Physician Global Assessment score ≥ 3 (moderate/moderate-to-severe/severe disease; 75.5%), psoriasis area severity index ≥ 10 (severe/extensive disease; 82.6%), nail or scalp involvement (52.8% and 75.5%, respectively), and reported moderate or extreme pain/discomfort (57.4%) and/or a Dermatology Life Quality Index (DLQI) > 10 (large/extremely large effect; 59.2%). Among 186 patients without CVD, 63.4% had an intermediate/high 10-year risk of CVD. Patients with darker skin (Fitzpatrick skin types IV-VI) reported worse QoL than those with lighter skin (Fitzpatrick skin types IV-VI, mean [SD] DLQI, 15.7 [7.9]; I-III, 13.9 [7.8]).

CONCLUSIONS

Our data indicate that patients with plaque psoriasis prescribed apremilast in UK clinical practice have a high comorbidity burden and long-term, moderate-to-severe disease with special-site involvement, uncontrolled by systemic therapy, and which had a large detrimental impact on their QoL. These data highlight the need for timely treatment with appropriate therapy following diagnosis.

Efficacy and Safety of Risankizumab in Patients with Psoriasis Showing Suboptimal Response to Secukinumab or Ixekizumab: Results from a Phase 3b, Open-Label, Single-Arm (aIMM) Study

INTRODUCTION

Risankizumab has demonstrated superior efficacy compared to other psoriasis treatments, including secukinumab, adalimumab, and ustekinumab; switching to risankizumab from other psoriasis treatments has shown superior clinical and quality of life (QoL) outcomes. We evaluated the efficacy and safety of directly switching patients with moderate-to-severe plaque psoriasis and a suboptimal response to interleukin (IL)-17 inhibitors (secukinumab or ixekizumab) to risankizumab.

METHODS

This 52-week, phase 3b study enrolled patients (≥ 18 years) with moderate-to-severe plaque psoriasis who had previously been treated with the recommended dose of secukinumab or ixekizumab for ≥ 6 months but did not achieve an optimal response (static Physician's Global Assessment [sPGA] 2/3; body surface are [BSA] 3- < 10%). Patients received subcutaneous risankizumab (150 mg) without washout. The primary endpoint was the proportion of patients achieving sPGA of 0/1 at week 16. Secondary endpoints included sPGA 0/1 at week 52, sPGA 0, Dermatology Life Quality Index (DLQI) 0/1, and Psoriasis Symptoms Scale (PSS) 0 at weeks 16 and 52. Safety was monitored throughout the study.

RESULTS

The study included 244 patients. sPGA 0/1 was achieved by 57.4% and 62.3% at week 16 and 52. At week 16, sPGA 0, DLQI 0/1, and PSS 0 were achieved by 20.5%, 40.2%, and 20.9%, respectively. At week 52, these proportions increased to 27.1% for sPGA 0, 47.2% for DLQI 0/1, and 27.5% for PSS 0. Most frequently reported adverse events (reported in ≥ 5% of patients) in risankizumab-treated patients were COVID-19 infection (8.6%) and nasopharyngitis (5.7%). No new safety signals were observed.

CONCLUSIONS

Directly switching to risankizumab improved outcomes and QoL in patients with moderate-to-severe psoriasis who had suboptimal responses to anti-IL-17 inhibitors (secukinumab or ixekizumab). The safety results are consistent with previously reported safety of risankizumab. This study supports the efficacy of risankizumab in patients previously treated with biologics, including IL-17 inhibitors, and suggests a direct switch to risankizumab for improved clinical outcomes and QoL.

The Psychology Behind the Efficacy of a Buddy System for Enhancing Retention in Dermatological Clinical Trials

Retention in dermatological clinical trials is critical for ensuring the validity and reliability of study outcomes, yet participant dropout remains a pervasive challenge. In this analysis, the primary aim is to explore the psychological mechanisms underpinning the efficacy of a buddy system in enhancing retention rates in such trials. The buddy system, where participants are paired with peers who have previously participated in similar clinical trials offers mutual support and leverages the principles of social bonding, accountability, and shared experience to foster commitment and reduce attrition. The novelty of this approach lies in its focus on the psychological and emotional dimensions of trial participation, rather than solely on logistical or incentive-based strategies. Implementing a buddy system draws on theories of social support and motivation, suggesting that the presence of a buddy can alleviate anxiety, increase perceived value, and enhance the overall clinical trial experience. Future research should investigate the long-term effects of buddy systems across diverse demographic groups and dermatological conditions, as well as potential adaptations for virtual trial settings. In conclusion, integrating a buddy system into dermatological clinical trials represents an innovative strategy that could significantly improve retention, thereby strengthening the robustness of clinical data and advancing dermatological research.

Patient-Identified Treatment Goals for Psoriatic Disease: Results From a US Patient Survey

Background

Despite advancements in the treatment landscape for psoriasis (PsO) and psoriatic arthritis (PsA), some patients may not achieve the desired disease improvement due to undertreatment. Understanding patient perspectives on treatment expectations can inform patient-centered decisions and enhance treatment satisfaction.

Objective

To describe patient-identified treatment goals and expectations for managing psoriatic disease.

Methods

A cross-sectional study was conducted using a survey through MyPsoriasisTeam, an online social community. The survey was available to its US-based patients aged ≥21 years with self-reported diagnoses of PsO and/or PsA. The study assessed patients' treatment goals, satisfaction with treatment outcomes, and satisfaction with health care providers (HCPs). Responses were summarized using descriptive statistics.

Results

This analysis included 386 patients (PsO, n = 130; PsA with/without PsO, n = 256). Treatment goals varied by psoriatic disease type. The top 3 treatment goals for PsO were reduce itching (73.1%), reduction in size/thickness (68.5%), and reduction in the number of plaques (63.1), and for PsA, were reducing joint pain (77.7%), lessening fatigue (64.8%), and reducing joint stiffness (62.1%). Patient satisfaction with treatment outcomes was low (extremely/very satisfied: PsO, 7.5%/8.5% and PsA, 9.2%/20.2%). Overall, 73.1% with PsO were treated by a dermatologist, and a dermatologist or rheumatologist treated 74.6% with PsA. Overall, patient satisfaction with HCPs who treated their disease was lacking (PsO, 19.3% and 19.3%; PsA, 27.3% and 33.6% were extremely and very satisfied, respectively).

Conclusion

These findings suggest the need for enhanced communication between patients and HCPs to align treatment goals and expectations and to improve treatment satisfaction and disease management.

Disparities and barriers to the access of biologics in moderate-to-severe adult psoriasis

Psoriasis is a chronic, relapsing inflammatory skin disorder that is associated with substantial physical and psychosocial comorbidity. Although biologic agents have offered transformative therapeutic advantages to those unresponsive to traditional treatments, data from recent literature indicate significant undertreatment of certain populations, highlighting potential barriers to access. This review aims to comprehensively elucidate barriers to biological therapy, addressing a recognized gap in the current literature. A search was conducted using MEDLINE, Embase, and Web of Science to investigate the obstacles and disparities that prevent access to biologic treatments in biologic-naïve psoriatic patients. Emergent themes were then systematically categorized into five primary domains: patient-level, prescriber-level, medicine-level, organizational-, and external environment-level factors. Our results demonstrate pronounced barriers and disparities encompassing increased age, race, socioeconomic status, rural location, cost and insurance, and insufficient knowledge that may hinder access to biologic treatments among psoriatic patients. Further research on how these barriers can be effectively addressed is needed to optimize treatment outcomes.

Acceptability of 'as needed' biologic therapy in psoriasis: insights from a multistakeholder mixed-methods study

BACKGROUND

Biologic therapies have led to increasing numbers of patients with psoriasis who have clear or nearly clear skin. It is current practice to continue biologic therapy indefinitely in these patients, which contributes to a substantial long-term drug and healthcare burden. 'As needed' biologic therapy in psoriasis may address this; however, our understanding of patient and clinician perceptions of this strategy is limited.

OBJECTIVES

The aim of this mixed-methods study was to gain insight into the perspectives of both patients and clinicians regarding the acceptability of an 'as needed' approach to biologic therapy in psoriasis, including potential barriers and enablers to implementation in routine care.

METHODS

We first conducted UK-wide online scoping surveys of patients with psoriasis and dermatology clinicians to explore their views on 'as needed' biologic therapy. Using topic guides informed by these survey findings, we then carried out qualitative focus groups with patients and clinicians. Themes were identified using reflexive thematic analysis.

RESULTS

Of 67 patients and 27 clinicians completing the scoping surveys, 67% (43 of 64 patients) and 78% (21 of 27 clinicians) supported the use of 'as needed' biologic therapy, respectively. Respondents highlighted advantages such as a reduction in healthcare burden and greater ownership of care. Challenges included logistics of 'as needed' drug provision and potential risks of disease flare and drug immunogenicity. Focus groups comprised 15 patients with psoriasis [9 female patients (60%), average disease duration 32 years (range 9-64)] and 9 dermatology clinicians [8 female clinicians (89%), average dermatology experience 20 years (range 8-33)]. Both patients and clinicians felt that an 'as needed' treatment approach will deliver a reduction in treatment burden and present an opportunity for patient-led ownership of care. Both groups highlighted the importance of ensuring ongoing access to medication and discussing the potential impact of psoriasis recurrence. Patient preferences were influenced by their lived experiences, particularly previous difficulties with medication delivery logistics and establishing disease control. Clinician perspectives were informed by personal experience of their patients adapting their own dosing schedules. Clinicians highlighted the importance of targeted patient selection for an 'as needed' approach, ongoing disease monitoring, and prompt reaccess to medications upon psoriasis recurrence.

CONCLUSIONS

These data indicate that 'as needed' biologic therapy in psoriasis is acceptable for both patients and clinicians. Formal assessment of clinical effectiveness and cost-effectiveness is warranted to enable the real-world potential of this approach to be realized.

Inflammatory memory in psoriasis: From remission to recurrence

The routine use of targeted systemic immunomodulatory therapies has transformed outcomes for people with severe psoriasis, with skin clearance (clinical remission) rates up to 60% at 1 year of biologic treatment. However, psoriasis may recur following drug withdrawal, and as a result, patients tend to continue receiving costly treatment indefinitely. Here, we review research into the "inflammatory memory" in resolved psoriasis skin and the potential mechanisms leading to psoriasis recurrence following drug withdrawal. Research has implicated immune cells such as tissue resident memory T cells, Langerhans cells, and dermal dendritic cells, and there is growing interest in keratinocytes and fibroblasts. A better understanding of the interactions between these cell populations, enabled by single cell technologies, will help to elucidate the events underpinning the shift from remission to recurrence. This may inform the development of personalized strategies for sustaining remission while reducing long-term drug burden.

Granzyme K mediates IL-23-dependent inflammation and keratinocyte proliferation in psoriasis

Psoriasis is an inflammatory disease with systemic manifestations that most commonly presents as itchy, erythematous, scaly plaques on extensor surfaces. Activation of the IL-23/IL-17 pro-inflammatory signaling pathway is a hallmark of psoriasis and its inhibition is key to clinical management. Granzyme K (GzmK) is an immune cell-secreted serine protease elevated in inflammatory and proliferative skin conditions. In the present study, human psoriasis lesions exhibited elevated GzmK levels compared to non-lesional psoriasis and healthy control skin. In an established murine model of imiquimod (IMQ)-induced psoriasis, genetic loss of GzmK significantly reduced disease severity, as determined by delayed plaque formation, decreased erythema and desquamation, reduced epidermal thickness, and inflammatory infiltrate. Molecular characterization in vitro revealed that GzmK contributed to macrophage secretion of IL-23 as well as PAR-1-dependent keratinocyte proliferation. These findings demonstrate that GzmK enhances IL-23-driven inflammation as well as keratinocyte proliferation to exacerbate psoriasis severity.

A value-based healthcare model for initiating and switching psoriasis therapies-Results from the prospective multicentre IMPROVE study

BACKGROUND

Little is known about the therapeutic benefits of a value-based healthcare model compared to a traditional activity-based incentive model in psoriasis (PsO).

OBJECTIVES

This prospective non-interventional study evaluated an outcome-based, patient-centred management model for patients with PsO.

METHODS

In total, 49 patients with a Psoriasis Area and Severity Index (PASI) ≥3 who were starting or switching between treatments were included. Patients were assessed at baseline, 3 and 9 months. The patient benefit index (PBI) was calculated using predefined questionnaires. An expected PBI was calculated and adjusted for risk factors known to complicate treatment, that is overweight and smoking. The model remunerated the department on whether the observed PBI exceeded the expected PBI to incentivize over-performance.

RESULTS

In total, 40 patients (80%) completed all three visits; 32.7% were smokers and 73.5% were overweight. Mean PASI at baseline was 11.5 (SD 9.1); PASI improved significantly from baseline through 3 months: mean reduction, 8.0 (SD 9.2), p < 0.001 and was maintained until 9 months: mean further reduction, 0.1 (SD 3.3), p = 0.893. The mean PBI was 2.5 (SD 1.3) and 2.8 (SD 1.1) at 3 and 9 months, respectively. A PBI ≥1 was achieved by 87.8% at 3 and 95.1% at 9 months. Overall, the department was remunerated a mean 2721.1 DKK (SD 4472.8) per patient. In subgroup analysis, the department was remunerated a mean of, respectively, 2428.6 (SD 5089.5), 2636.6 (SD 4471.3) and 3196.5 (SD 4497.1) DKK for patients with none, 1 or 2 risk factors, that is smoking or/and overweight.

CONCLUSIONS

The model evaluated herein is the first value-based model to calculate remuneration from patient reported outcomes and showed to successfully predict the expected PBI and remunerate treatment based on whether the expected treatment goal was met or exceeded. This can be utilized in the patient-centred management of PsO.

Disease clearance in ulcerative colitis: A new therapeutic target for the future

Advancements in murine modeling systems for ulcerative colitis have diversified our understanding of the pathophysiological factors involved in disease onset and progression. This has fueled the identification of molecular targets, resulting in a rapidly expanding therapeutic armamentarium. Subsequently, management strategies have evolved from symptomatic resolution to well-defined objective endpoints, including clinical remission, endoscopic remission and mucosal healing. While the incorporation of these assessment modalities has permitted targeted intervention in the context of a natural disease history and the prevention of complications, studies have consistently depicted discrepancies associated with ascertaining disease status through clinical and endoscopic measures. Current recommendations lack consideration of histological healing. The simultaneous achievement of clinical, endoscopic, and histologic remission has not been fully investigated. This has laid the groundwork for a novel therapeutic outcome termed disease clearance (DC). This article summarizes the concept of DC and its current evidence.

Implementing well-being in the management of psoriasis: An expert recommendation

Psoriasis causes detriment in a person's physical, mental and social health which impairs their quality of life (QoL). However, the current psoriasis management may not adequately address all relevant health domains. Since the goal of healthcare is to restore or maintain health, health outcomes should include all areas of the patient's overall health. Life satisfaction, QoL and patient well-being are essential to a comprehensive approach to the disease. With the inclusion of more people-centred policies, care of patients with psoriasis should evolve towards a holistic and integrated assessment of the disease impact, including subjective measures of well-being in order to encompass all aspects of health. The main objective of this expert review is to give the concept of well-being a place as an entity within the holistic therapeutic approach for patients with psoriasis. Identifying and defining common goals beyond the skin with the patient and testing them throughout the course of treatment will benefit and enhance treatment success. We propose a series of recommendations for application in clinical practice, providing tangible clinical guidance for implementing well-being in the management of psoriasis. Among the recommendations are the need to initially listen to the patient, to know their level of empowerment or what they want to achieve, their preferences in decision making, the evaluation of not only the physical but also the emotional impact of the disease (well-being), the definition of the aspects that can generate a cumulative deterioration of the disease throughout life, and a continuous assessment of the patient's preferences with the opinion of the expert clinician and the integration of the knowledge of external clinical evidence.

Tapinarof cream 1% once daily for the treatment of adults with mild to severe plaque psoriasis: A novel topical therapy targeting the aryl hydrocarbon receptor

Plaque psoriasis is a chronic, immunemediated skin disease characterized by scaly, erythematous, pruritic plaques. The effects of psoriasis are often debilitating and stigmatizing, significantly impacting patients' physical and psychological well-being and quality of life. Current guideline-recommended psoriasis therapies (topicals, oral systemics, and biologics) have substantial limitations that include overall efficacy, safety, tolerability, sites of application, disease severity, and duration and extent of body surface area treated. Due to these limitations, psoriasis treatment regimens often require combination therapy, especially for moderate to severe disease, leading to increased treatment burden. Psoriasis is also associated with increased indirect costs (eg, reduced work productivity), leading to greater total costs expenditures. Thus, more effective, safe, well-tolerated, and cost-effective therapeutic options are needed. Tapinarof cream 1% once daily is a first-in-class, nonsteroidal, topical aryl hydrocarbon receptor agonist approved by the US Food and Drug Administration in 2022 for the treatment of plaque psoriasis in adults. Tapinarof cream has been evaluated in plaque psoriasis, including 2 pivotal phase 3 trials (NCT03956355 and NCT03983980) and a long-term extension trial (NCT04053387). These trials demonstrated high rates of complete skin clearance with tapinarof cream, durable effects while on treatment (a lack of tachyphylaxis for up to 52 weeks), an approximately 4-month remittive effect off therapy after achieving complete clearance and stopping treatment (ie, duration during which psoriasis does not recur off therapy), and no rebound effects after cessation of therapy. According to the US Food and Drug Administration-approved prescribing information, tapinarof may be used to treat plaque psoriasis of any severity and in any location, has no restrictions on duration of use or extent of total body surface area treated, and has no contraindications, warnings, precautions, or drug-drug interactions. Tapinarof cream is thus an efficacious, well-tolerated, steroid-free topical option that addresses many of the limitations of current recommended therapies. Here we review current knowledge on the physical, psychological, and financial burdens of plaque psoriasis and identify how the clinical profile of tapinarof cream can address key treatment gaps important in the management of plaque psoriasis and patient quality of life. In this article, we aim to assist pharmacists and other managed care practitioners by providing an evidence-based overview of tapinarof cream to support patient-centric decision-making.

Comparison of risankizumab and apremilast for the treatment of adults with moderate plaque psoriasis eligible for systemic therapy: results from a randomized, open-label, assessor-blinded phase IV study (IMMpulse)

BACKGROUND

Treatment of psoriasis with risankizumab has demonstrated superior efficacy to other treatments, such as adalimumab, ustekinumab and secukinumab.

OBJECTIVES

This study compared the efficacy and safety of risankizumab and apremilast in adults with moderate plaque psoriasis eligible for systemic therapy. It also evaluated the efficacy and safety of switching to risankizumab vs. continuing apremilast in patients who did not achieve ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75 nonresponders) after 16 weeks of treatment with apremilast.

METHODS

This 52-week, phase IV, multicentre, randomized, open-label, efficacy assessor-blinded study (NCT04908475) enrolled patients (aged ≥ 18 years) with a diagnosis of moderate chronic plaque psoriasis (≥ 6 months) and who were candidates for systemic therapy. The enrolled patients (randomized 1 : 2) received subcutaneous risankizumab (150 mg at weeks 0 and 4) or oral apremilast (30 mg twice daily). At week 16, all patients treated with apremilast were re-randomized (1 : 1) to risankizumab or apremilast, stratified by week-16 PASI 75 response. The co-primary outcomes in period A at week 16 were the achievement of ≥ 90% improvement in Psoriasis Area and Severity Index (PASI 90) and static Physician's Global Assessment (sPGA) 0/1 with a two-grade or better improvement from baseline. At week 52, the primary endpoint in period B was the achievement of PASI 90 in PASI 75 nonresponders with apremilast at week 16. Safety was monitored throughout the study. All patients who received one dose of treatment were included in the efficacy and safety analysis.

RESULTS

At baseline, 118 and 234 patients were assigned to receive risankizumab and apremilast, respectively. At week 16, PASI 90 was achieved by 55.9% [95% confidence interval (CI) 47.0-64.9] and 5.1% (95% CI 2.3-8.0), and sPGA 0/1 by 75.4% (95% CI 67.7-83.2) and 18.4% (95% CI 13.4-23.3), respectively. In period B, among PASI 75 nonresponders with apremilast at week 16, 83 switched to risankizumab and 78 continued apremilast. At week 52, 72.3% (95% CI 62.7-81.9) who switched to risankizumab achieved PASI 90 vs. 2.6% (95% CI 0.0-6.1) who continued apremilast. The most frequent adverse events (reported in ≥ 5%) in risankizumab-treated patients were COVID-19 infection and nasopharyngitis. Diarrhoea, nausea and headache were most frequent among apremilast-treated patients.

CONCLUSIONS

For patients with moderate psoriasis, treatment with risankizumab demonstrated superior efficacy to those treated with apremilast, including those who did not benefit from prior treatment with apremilast. The safety profile of risankizumab was similar to prior studies, and no new safety signals were identified. These results show that, compared with apremilast, risankizumab treatment can significantly improve clinical outcomes in systemic-eligible patients with moderate psoriasis.

Pain associated with psoriasis: a qualitative study

BACKGROUND

Pain is a major factor in the psychosocial impact of psoriasis. There is a paucity of qualitative reports of dermatologists' views on psoriasis-related pain.

OBJECTIVES

The aim of this study was to explore the views of dermatologists on the presence and importance of pain associated with psoriasis.

METHODS

This qualitative study, based on semi-structured interviews, included dermatologists from different cities working in the hospital and private sector in Croatia between May and July, 2022. We collected demographic and occupational data on participants and information about their experiences and attitudes toward psoriasis-related pain. Data were analysed by applying interpretative descriptive and thematic analysis using the 4-stage method for systematic text condensation.

RESULTS

We included 19 dermatologists, all women, aged 38 (range: 31 to 63 years). Most dermatologists acknowledged the presence of pain in patients with psoriasis. They indicated that they sometimes do not sufficiently address this pain in daily practice. Some indicated that pain was a neglected symptom in psoriasis, while for others it was not crucial. Most indicated that it is necessary to focus more on psoriasis-related pain in clinical practice, to disambiguate between skin pain and joint pain in psoriatic conditions, and to better educate family physicians about psoriasis-related pain. They emphasized the importance of considering pain during psoriatic patient assessment and management. Further research on psoriasis-related pain was suggested.

CONCLUSIONS

More emphasis is needed on psoriasis-related pain for effective management of psoriasis, informing decision-making in the context of patient-centric care and improving the quality of life in patients with psoriasis.

Phytochemical investigation, structural elucidation, in silico study and anti-psoriatic activity of potent bioactive from Betula utilis

Psoriasis is a chronic autoimmune pathological condition characterized by hyperactivation of proinflammatory cytokines (IL-6, TNF-α, IL-17, IL-23, etc.). Severe drug-associated toxicities like hepatotoxicity and nephrotoxicity (Methotrexate), teratogenicity (Tazarotene), hypercholesterolemia (Cyclosporine) and hypercalcemia (tacalcitol), are the forefront challenges that demand an alternative approach for the treatment of psoriasis. In the present study, a natural lead molecule 'Betulin' (BE, lup-20(29)-ene-3b,28-diol) was isolated from Betula utilis and subsequently, structure-based molecular docking was employed to identify the molecular target for psoriasis. The computational analysis reflects better affinity of BE towards pro-inflammatory cytokine as compared to standard drugs. Apart from this BE shows a greater affinity towards the overexpressed Glut-1 receptor in comparison to standard drug Metformin (Met). Based on the in silico screening the isolated lead compound was further processed for the evaluation of anti-psoriatic activity via imiquimod (IMQ 5%) induced psoriasis-like skin inflammation model. In vivo screening models were characterized by different parameters (psoriasis area and severity index (PASI) scores, macroscopically and behavioral evaluation, splenomegaly, cytokine levels and histological changes) and compared among the experimental groups. The experimental finding reflects comparable results of PASI score, i.e., 57.14% and 61.9% recovery of test BE-solution (180 mg/kg) and standard Betamethasone di-propionate ointment (BD-oint.0.5 mg/g), respectively. Focusing on other parameters, BE shows relative results such as an enhanced macroscopically with behavioral conditions, reducing the expression of proinflammatory cytokine as well as restoring histological changes with that of BD. These findings suggest that BE-isolated phytoconstituents from Betula utilis could be a potential agent and a step closer to psoriasis treatment. HIGHLIGHTPsoriasis is a multifaceted, immunologically mediated disease consequences production of high levels of proinflammatory mediators and overexpression of Glut-1 transporters that trigger keratinocyte proliferation and inflammatory cascades.A Himalayan silver birch, Betula utilis (Bhojpatra) contains many steroidal terpenes which are responsible for various pharmacological activities that could be exploited in drug development in psoriasis.The computational analysis of BE reflects a better affinity toward the proinflammatory cytokines with their target receptors and indicates a satisfactory range with a slight deviation from Jorgensen and Lipinski's rule and possesses a significant drug choice for psoriasis.Preclinical findings of BE-solution (BE-sol) give a positive response towards IMQ-induced psoriasis-like skin inflammation model.[Figure: see text]Communicated by Ramaswamy H. Sarma.

Psoriasis immunometabolism: progress on metabolic biomarkers and targeted therapy

Psoriasis is a common inflammatory disease that affects mainly the skin. However, the moderate to severe forms have been associated with several comorbidities, such as psoriatic arthritis, Crohn's disease, metabolic syndrome and cardiovascular disease. Keratinocytes and T helper cells are the dominant cell types involved in psoriasis development via a complex crosstalk between epithelial cells, peripheral immune cells and immune cells residing in the skin. Immunometabolism has emerged as a potent mechanism elucidating the aetiopathogenesis of psoriasis, offering novel specific targets to diagnose and treat psoriasis early. The present article discusses the metabolic reprogramming of activated T cells, tissue-resident memory T cells and keratinocytes in psoriatic skin, presenting associated metabolic biomarkers and therapeutic targets. In psoriatic phenotype, keratinocytes and activated T cells are glycolysis dependent and are characterized by disruptions in the TCA cycle, the amino acid metabolism and the fatty acid metabolism. Upregulation of the mammalian target of rapamycin (mTOR) results in hyperproliferation and cytokine secretion by immune cells and keratinocytes. Metabolic reprogramming through the inhibition of affected metabolic pathways and the dietary restoration of metabolic imbalances may thus present a potent therapeutic opportunity to achieve long-term management of psoriasis and improved quality of life with minimum adverse effects.

Patient-reported well-being in value-based care using tildrakizumab in a real-world setting: protocol of a multinational, phase IV, 1-cohort prospective observational study (the POSITIVE study)

INTRODUCTION

Psoriasis is a chronic inflammatory skin disease that negatively impacts the quality of life of patients and their families. However, the most commonly used decision-making tools in psoriasis, Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA) and Dermatology Life Quality Index (DLQI), do not fully capture the impact of psoriasis on patients' lives. In contrast, the well-established 5-item WHO Well-being Index (WHO-5) assesses the subjective psychological well-being of patients. Moreover, while drug innovations became available for psoriasis, data on the impact of these therapies on patients' lives and their closest environment (family, physicians) are limited. This study will assess the effect of tildrakizumab, an interleukin-23p19 inhibitor, on the overall well-being of patients with moderate-to-severe psoriasis. Moreover, the long-term benefit of tildrakizumab on physicians' satisfaction and partners' lives of patients with psoriasis will be evaluated.

METHODS AND ANALYSIS

This non-interventional, prospective, observational, real-world evidence study will involve multiple sites in Europe and approximately 500 adults with moderate-to-severe psoriasis treated with tildrakizumab. Each patient will be followed for 24 months. The primary endpoint is well-being measured by the WHO-5 questionnaire. Key secondary endpoints include Physician's Satisfaction and partner's quality of life (FamilyPso). Other endpoints will evaluate skin-generic quality of life (DLQI-R), Treatment Satisfaction Questionnaire for Medication (TSQM-9), Treatment-related Patient Benefit Index 'Standard', 10 items (PBI-S-10) and work productivity and activity impairment due to psoriasis (WPAI:PSO). Statistical analyses will be based on observed cases. Multiple imputations will be performed as a sensitivity analysis, and adverse events will be reported.

ETHICS AND DISSEMINATION

The study will be conducted according to the protocol, which received ethics committee approval and applicable regulatory requirements of each participating country. The results will be disseminated through scientific publications and congress presentations.

The social value of a PASI 90 or PASI 100 response in patients with moderate-to-severe plaque psoriasis in Spain

Introduction

Psoriasis is a chronic disease involving the skin, which significantly impacts the quality of life. Disease severity and treatment efficacy (i.e., response) are assessed through the Psoriasis Area and Severity Index (PASI). A PASI 75 response, i.e., an improvement of at least 75% with respect to the baseline PASI score, has traditionally been used as a therapeutic benchmark in clinical trials. Therapeutic advances have made PASI 90 or PASI 100 responses possible in most patients treated with some biologics. A greater response may generate social value beyond clinical outcomes that would benefit both patients and society.

Methods

A 1-year economic model was applied to estimate the impact of having a PASI 75, PASI 90, or PASI 100 response in four areas of analysis (quality of life, activities of daily living, work productivity, and out-of-pocket expenditures) and the social value of having a PASI 90 or PASI 100 response in comparison with a PASI 75 response. A mixed-methods approach based on the scientific literature, a focus group with patient, and an advisory committee with psoriasis stakeholders was used. The model included three different scenarios: having a PASI 90 vs a PASI 75 response; a PASI 100 vs a PASI 90 response; and a PASI 100 vs a PASI 75 response. A sensitivity analysis was included.

Results

The annual economic impact per patient with moderate-to-severe plaque psoriasis having a PASI 75 response was estimated at Ł 6,139, mainly related to labour productivity losses and quality of life reductions. Having a PASI 90 or a PASI 100 response would reduce this impact to €3,956 or €1,353, respectively. Accordingly, the social value of having a PASI 90 instead of a PASI 75 response was estimated at €2,183, and €4,786 with a PASI 100 response.

Discussion

A PASI 90 or PASI 100 response would have a lower economic impact and a greater social value than a PASI 75 response for patients with moderate-to-severe plaque psoriasis.

Engaging psoriasis patients in adherence and outcomes to topical treatments: A summary from the Symposium 'Tailoring topical psoriasis treatments to patients' needs and expectations' of the 30th EADV Congress 2021

This article is based on a presentation given by authors at the Satellite Symposium titled 'Tailoring topical psoriasis treatments to patients' needs and expectations' held during the 30^th European Academy of Dermatology and Venereology Congress. During this session, the factors affecting adherence and outcomes to topical treatments were presented, with a particular focus on the patients' point of view. Psoriasis is not just a skin condition. Psoriasis can cause negative psychosocial effects, such as depression and anxiety. The risk of suicidality in patients with psoriasis is higher than in the background population. Psychosocial comorbidities can be prevented by patient involvement in psoriasis management and need to be treated in a multidisciplinary manner. Adherence may be the largest barrier to treatment success with topical therapies. Improvement in several areas of disease management may lead to benefits in treatment adherence and hence clinical benefit. There are several treatment-related factors for non-adherence, such as patient dissatisfaction, side effects, treatment regimen or the drug vehicle. Delivering comprehensive treatment information to the patient will help develop realistic objectives and expectations. Patients need to be involved in the selection of treatment strategies, as psoriasis patients have various preferences for their use of topical treatments. A shared decision-making with the patient has been shown to improve medication adherence and treatment success. Prescribing therapy in line with a patient preference for treatment vehicle and improving the communication between healthcare professionals and patients may be key factors to maximize adherence. The calcipotriol (CAL) and betamethasone dipropionate (BDP) cream, a novel formulation of the CAL/BDP fixed-dose combination based on Poly-Aphron Dispersion (PAD) Technology, is a topical treatment of mild-to-moderate plaque psoriasis, including scalp psoriasis, that has high cosmetic acceptance and overall treatment satisfaction.

Switching to risankizumab from ustekinumab or adalimumab in plaque psoriasis patients improves PASI and DLQI outcomes for sub-optimal responders

BACKGROUND

Psoriasis is often treated with biologic therapies. While many patients see improvement in their symptoms with treatment, some achieve only partial success.Objective and Methods: In this post-hoc analysis we assess Psoriasis Area Severity Index (PASI) and Dermatology Life Quality Index (DLQI) results from patients who switched to RZB due to suboptimal results that originally received ADA (N = 53, IMMvent NCT02694523) or UST (N = 172, UltIMMa-1 [NCT02684370], UltIMMa-2 [NCT02684357]).

RESULTS

For patients originally treated with ADA, after three doses of RZB, 83.3% of PASI 50 to <75 patients improved to PASI ≥75 and for PASI 75 to <90 patients, 77.1% improved to PASI ≥90. For patients originally treated with UST, after 7 doses of RZB, 86.8% of PASI <75 patients improved to PASI ≥75 and 75.5% of PASI 75 to ≤90 patients improved to PASI ≥90. No patients demonstrated worsening from their initial PASI group after switching. There were no significant safety events associated with switching patients to RZB without a washout period.

CONCLUSION

For patients with an inadequate or incomplete response to UST or ADA, switching to RZB improved PASI scores and DLQI for patients with moderate to severe plaque psoriasis with no significant safety risks.

Health literacy and medication adherence in psoriasis patients: a survey in Iran

BACKGROUND

Medication adherence among Psoriasis patients is often inadequate identified as a significant problem in Psoriasis symptoms management. Poor medication adherence could necessitate stronger and more expensive medications, which could place a significant burden on the healthcare system. Moreover, the importance of health literacy assessment as a factor influencing adherence in psoriasis patients cannot be overstated. This study aimed to evaluate the medication adherence level of Iranian Psoriasis patients and its relationship with the patients' health literacy level and demographic conditions.

METHODS

This is a cross-sectional study among Iranian psoriasis patients conducted through a web-based questionnaire survey between 26 July 2020 and 5 January 2021 and a total of 575 samples were collected. The questionnaire consisted of 3 sections: First, demographic information and disease characteristics were evaluated. Second, the medication adherence was evaluated by using valid Morisky Medication Adherence Scale-8 (MMAS-8), and, finally, the health literacy was evaluated by using Health Literacy for Iranian Adults (HELIA). Data were analyzed using SPSS software, version 22 with descriptive statistics; Chi-square and Kruskal-Wallis tests. Stepwise multiple linear regression was also used to evaluate the impact of independent variables related on medication adherence score.

RESULTS

Results showed that the mean health literacy score in the study population was 74.3 ± 14.23, and the mean medication adherence score was 4.1 ± 2.18. Out of the total participants, 28.8% had high health literacy, 67.1% had adequate health literacy, and 4% had inadequate health literacy. The majority of the participants (70.7%) reported low adherence, while 24.1% reported moderate and 5.2% reported high adherence. The results of the Chi-square test showed a significant relationship between age, comorbidities, type of treatment, satisfaction with treatment, the experience of adverse effects, and health literacy with medication adherence (P < 0.05 for all). The final constructed model of stepwise multiple linear regression was highly statistically significant. The highest beta coefficient in the final model belonged to the total health literacy score.

CONCLUSIONS

Based on the results, medication adherence among Iranian psoriasis patients is low. Health literacy correlates most strongly with medication adherence and is the best variable to determine it. Improving the access to the internet and the ICTs to enhance the patients` health literacy along with developing the patient education approaches and techniques should be considered by health policymakers.

Short Term and Long-Term Efficacy of Calcipotriene/ Betamethasone Dipropionate Foam Combination

Psoriasis is a well-known chronic disease characterized by the development of erythematous, indurated, scaly, pruritic plaques on the skin with cycles of remission and symptom flare-ups. The management of patients with chronic plaque psoriasis has been more challenging since the Covid-19 pandemic as health care professionals have had to adapt to remote consultations for some patients, and patients have had to adapt to the changing health landscape. The rapid resolution of psoriasis symptoms especially those with a substantial impact on quality of life can improve patient satisfaction and adherence, making it an important factor in successful treatment. Cal/BD foam contributes to improved patient adherence and treatment outcome through its rapid action and superior efficacy versus Cal or BD monotherapy, Cal/BD ointment and gel and clobetasol cream in the short-term flare treatment of psoriasis. Moreover, the benefits of proactive long-term management of psoriasis compared to reactive management and its favourable safety profile are higher efficacy and a better health-related quality of life. Cal/BD foam should be considered an effective topical treatment for short-term flare treatment and long-term control of adult psoriatic patients.

Relevant associations between alexithymia and health-literacy in persons with psoriasis

OBJECTIVE

To explore possible associations between alexithymia and health literacy (HL) in persons with psoriasis.

METHODS

We conducted a cross-sectional study, including 825 persons with moderate to severe psoriasis, using the Toronto Alexithymia Scale, and the Health Literacy Questionnaire. Descriptive statistics compare HL means between alexithymic and not alexithymic participants. Associations between alexithymia and HL are analyzed using a linear multiple regression model.

RESULTS

Twenty-six percent of the participants were characterized as alexithymic, and 26.8% had borderline alexithymia. Higher alexithymia scores were associated with lower education, biological medicines, and more comorbidities, together with lower self-efficacy. The HL domains with the strongest associations with alexithymia were those focusing on managing and getting support for health, as well as the ability to find health information.

CONCLUSION

A more elevated alexithymia score is associated with lower HL. Further studies of these associations may contribute to a more comprehensive perspective of psoriasis. To know a patient's alexithymia level and HL needs may guide health care personnel's understanding of possible associations between health status, clinical presentation, behavior, and response to treatment.

Treatment Goals for Psoriasis as Measured by Patient Benefit Index: Results of a National Psoriasis Foundation Survey

INTRODUCTION

This cross-sectional survey was conducted with National Psoriasis Foundation (NPF) to capture treatment perspectives and expectations in patients with psoriasis (PsO) using Patient Needs Questionnaire (PNQ) of Patient Benefit Index (PBI).

METHODS

Adult participants with self-reported diagnosis of PsO responded to the PNQ portion of PBI by indicating how much they valued different treatment attributes. All the treatment goals were captured on a five-point Likert scale (0 = "Not important", 4 = "Very important"). Treatment goals were obtained for overall population and subgroups based on severity of disease Patient Global Assessment (PGA), age, gender, and Dermatology Life Quality Index (DLQI) total score. All data were expressed as mean and standard deviation [SD].

RESULTS

A total of 1200 participants completed the survey (mean age 51.5 years). Top treatment goal in the overall population was "to have confidence in the therapy" (3.46 [1.01]). Unique to the higher severity subgroup (PGA ≥ 3), "to find a clear diagnosis and therapy" was a top five goal and "to get better skin quickly" was for those with lesser severity (PGA < 3). "To be free of itching" (3.36 [0.99]) was the unique goal in the < 40 age group whereas it was "to get better skin quickly" (3.27 [1.12]) in the ≥ 40 group. In women and men, "to be free of itching" (3.38 [1.13]) and "to get better skin quickly" (3.20 [1.09]) were top five goals, respectively. Patients with ≥ 10 DLQI scores expressed higher treatment goal "to regain control of the disease" (3.66 [0.67]) compared to those with ≤ 10 DLQI scores who expressed "to have confidence in the therapy" (3.40 [1.11]) as the topmost treatment goal.

CONCLUSION

Our results suggest that in patients with PsO, treatment preferences can vary with different characteristics such as age, severity, and gender as measured by using PNQ. Further exploration of this data will help inform treatment decisions and optimize patient outcomes.

Using the patient-acceptable symptom state to evaluate patients' perspectives of living with psoriasis: A cross-sectional study

BACKGROUND

Taking the perspectives of patients into consideration is of the utmost importance when defining treatment goals for psoriasis. The patient-acceptable symptom state (PASS) is a dichotomised question that captures patients' perceptions of their overall health state.

OBJECTIVES

To evaluate PASS and determine the factors associated with a satisfactory PASS for psoriatic patients.

METHODS

Three questions were asked: (Q1) Considering the ways that your skin symptoms affect your functioning, is your current skin psoriasis satisfactory? (Current PASS), (Q2) Considering the ways that your psoriasis is affecting you, if you were to remain in this state for the next few months, would this be satisfactory? (Future PASS) and (Q3) If you were to remain for the rest of your life as you were during the last 48 hours, would this be satisfactory? (Lifelong PASS). Disease severity, symptoms and health-related quality of life (HRQoL) were collected.

RESULTS

Of 140 patients, 74.3%, 70.0% and 85.7% expressed satisfaction with their current, future and lifelong skin psoriasis conditions respectively. A satisfactory PASS was significantly associated with older and married patients; lower disease severity; fewer skin symptoms; and a higher HRQoL. A multivariate analysis revealed that the independent factors associated with a satisfactory PASS were being older than 40 years, being married, practising meditation, not having extensive lesions at sensitive areas and having a high HRQoL.

CONCLUSIONS

PASS is a simple and easily administered questionnaire that reflects both disease severity and HRQoL. Understanding patients' needs and satisfaction levels will result in better care for psoriatic patients than otherwise.

Freedom from disease in psoriasis: a Delphi consensus definition by patients, nurses and physicians

Background

Physician‐reported clinical outcome and quality of life (QoL) measures are currently used to assess outcomes and direct treatment of plaque psoriasis. However, people with psoriasis may have different criteria for judging treatment success.

Objectives

To build a unified consensus on the definition of ‘freedom from disease’ from a European stakeholder group, including people with psoriasis, dermatologists and nurses.

Methods

The modified Delphi consensus methodology was used to define ‘freedom from disease’, with a consensus group consisting of people with psoriasis, nurses and dermatologists. This methodology involved people with psoriasis during the entire process and consisted of a 15‐member Facilitating Consensus Panel to drive the programme content and a larger Voting Consensus Panel to vote on defining ‘freedom from disease’. The Facilitating Panel agreed on disease domains, and aspects of each domain were put forward to the Voting Consensus Panel to establish relative importance. Following two voting rounds, a meeting was held to agree on a final consensus statement.

Results

The Facilitating Panel consisted of six patient advocacy group representatives, three specialist nurses and six dermatologists. Voting rounds 1 and 2 were completed by 166 and 130 respondents from the Voting Consensus Panel, respectively. The outputs from both rounds of voting were similar, focusing on normality of living, symptom control, and a relationship of mutual respect and trust between the individual with psoriasis and their healthcare professional. The consensus statement emphasizes that ‘freedom from disease’ is multifaceted and includes the following domains ‘management of clinical symptoms’, ‘psychosocial elements’, ‘QoL and well‐being’, ‘treatment’ and ‘healthcare team support’. ‘Freedom from disease’ means all aspects are addressed.

Conclusions

Freedom from disease in psoriasis is a multicomponent concept including five main domains. This diverse and multifaceted patient perspective will help us to improve understanding of the outcomes of treatment interventions in people with psoriasis.

Long-term maintenance treatment of psoriasis: the role of calcipotriol/betamethasone dipropionate aerosol foam in clinical practice

Most patients with psoriasis present with localized mild-to-moderate disease. In this case, the application of topical treatments in the first-line setting is recommended in most cases.Among different topical options, the fixed-dose combination of betamethasone dipropionate (BD) and vitamin D analogue (Cal) aerosol foam (Enstilar®, Leo Pharma) is approved as first-line topical therapy for the treatment of psoriasis in USA and the EU, due to its high efficacy and its favorable administration scheme.The PSO-LONG was the first trial to report on the long-term efficacy and safety of the Cal/DB foam treatment for the proactive management of psoriasis and now, the indications of Cal/BD foam included its use in the psoriasis maintenance treatment. However, the precise role of this treatment and the potential therapeutic schemes in the long-term management of psoriasis need further clarification.This Position Paper, authored by a group of Italian Expert Dermatologists, critically discusses the long-term management of psoriasis with Cal/BD foam in clinical practice. In particular, the biological rationale in the proactive treatment with Cal/BD foam and current evidence regarding this therapeutic approach are presented, along with its application also in patients with moderate-to-severe disease, difficult-to-treat lesions, or within combination regimens. In addition, strategies to improve adherence to long-term treatment of psoriasis are discussed.

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

Background

Psoriasis has important physical and psychosocial effects that extend beyond the skin. Understanding the impact of treatment on health‐related quality of life (HRQoL) and patient‐perceived symptom severity in psoriasis is key to clinical decision‐making.

Objectives

This post hoc analysis of the PSO‐LONG trial data assessed the impact of long‐term proactive or reactive management with fixed‐dose combination calcipotriene 50 µg/g and betamethasone dipropionate 0.5 mg/g (Cal/BD) foam on patient‐reported outcomes (PROs) in patients with psoriasis vulgaris.

Methods

Five hundred and twenty‐one patients from the Phase 3, randomized, double‐blind PSO‐LONG trial were included. An initial 4‐week, open‐label phase of fixed‐dose combination Cal/BD foam once daily (QD) was followed by a 52‐week maintenance phase, at the start of which patients were randomized to a proactive management arm (Cal/BD foam twice weekly) or reactive management arm (vehicle foam twice weekly). Patient‐perceived symptom severity and HRQoL were assessed using the Psoriasis Symptom Inventory (PSI), the Dermatology Life Quality Index (DLQI) and the EuroQol‐5D for psoriasis (EQ‐5D‐5L‐PSO).

Results

Statistically and clinically significant improvements were observed across all PRO measures. The mean difference (standard deviation) from baseline to Week 4 was −8.97 (6.18) for PSI, −6.02 (5.46) for DLQI and 0.11 (0.15) for EQ‐5D‐5L‐PSO scores. During maintenance, patients receiving reactive management had significantly higher DLQI (15% [p = 0.007]) and PSI (15% [p = 0.0128]) and a numerically lower EQ‐5D‐5L‐PSO mean area under the curve score than patients receiving proactive management (1% [p = 0.0842]).

Conclusions

Cal/BD foam significantly improved DLQI, EQ‐5D‐5L‐PSO and PSI scores during the open‐label and maintenance phases. Patients assigned to proactive management had significantly better DLQI and PSI scores and numerically better EQ‐5D‐5L‐PSO versus reactive management. Additionally, baseline flare was associated with worse PROs than the start of a relapse, and patients starting a relapse also had worse PROs than patients in remission.

Effectiveness and clinical predictors of drug survival in psoriasis patients receiving apremilast: A registry analysis

Background

Little is known about the effectiveness and drug survival associated with apremilast under real-world conditions.

Objective

To investigate the influence of patient and disease characteristics on drug survival associated with apremilast and to elucidate clinical effectiveness with regard to the psoriasis area and severity index (PASI) reduction.

Methods

This was an observational, retrospective, multicenter analysis from the Austrian Psoriasis Registry.

Results

Data from 367 patients were eligible for analysis. The 12-month drug survival rate associated with apremilast (ie, the proportion of patients on the drug) was 57.3% and decreased significantly in patients younger than 40 years (relative hazard ratio = 1.49, P = .007918). Sex; concomitant arthritis; previous biologic therapy; obesity; and palmoplantar, scalp, nail, and intertriginous involvement did not significantly affect drug survival. At 12 months, the response rates in patients receiving apremilast per protocol with a PASI of 50, 75, 90, and 100 were 80.0%, 56.4%, 38.2%, and 22.7%, respectively.

Limitations

Inclusion of a substantial number of patients with no record of absolute PASI at study entry and lack of PASI reduction follow-up data of 103 patients (28.1%) after starting apremilast treatment.

Conclusion

Apremilast is a robust antipsoriatic drug for which the drug survival is not strongly influenced by most patient- or disease-related factors except age. Drug survival is significantly shorter in patients younger than 40 years.

Network analysis of potential risk genes for psoriasis

Background

Psoriasis is a complex chronic inflammatory skin disease. The aim of this study was to analyze potential risk genes and molecular mechanisms associated with psoriasis.

Methods

GSE54456, GSE114286, and GSE121212 were collected from gene expression omnibus (GEO) database. Differentially expressed genes (DEGs) between psoriasis and controls were screened respectively in three datasets and common DEGs were obtained. The biological role of common DEGs were identified by enrichment analysis. Hub genes were identified using protein–protein interaction (PPI) networks and their risk for psoriasis was evaluated through logistic regression analysis. Moreover, differentially methylated positions (DMPs) between psoriasis and controls were obtained in the GSE115797 dataset. Methylation markers were identified after comparison with the common genes.

Results

A total of 118 common DEGs were identified, which were mainly involved in keratinocyte differentiation and IL-17 signaling pathway. Through PPI network, we identified top 10 degrees as hub genes. Among them, high expression of CXCL9 and SPRR1B may be risk factors for psoriasis. In addition, we selected 10 methylation-modified genes with the higher area under receiver operating characteristic curve (AUC) value as methylation markers. Nomogram showed that TGM6 and S100A9 may be associated with an increased risk of psoriasis.

Conclusion

This suggests that immune and inflammatory responses are active in keratinocytes of psoriatic skin. CXCL9, SPRR1B, TGM6 and S100A9 may be potential targets for the diagnosis and treatment of psoriasis.

Correlation Between Change in Psoriasis Area and Severity Index and Dermatology Life Quality Index in Patients with Psoriasis: Pooled Analysis from Four Phase 3 Clinical Trials of Secukinumab

INTRODUCTION

Patients with psoriasis (PsO) experience impaired health-related quality of life due to physical and psychosocial burdens. The objective of this study was to assess the correlation between change in Psoriasis Area and Severity Index (PASI) score and selected Dermatology Life Quality Index (DLQI) domain scores in patients with moderate-to-severe PsO and those with PsO and comorbid psoriatic arthritis (PsA).

METHODS

This post hoc analysis of four phase 3 clinical trials included patients with moderate-to-severe PsO randomized to secukinumab 150/300 mg, etanercept, or placebo. Pairwise latent growth models were applied to assess the longitudinal correlation between change in PASI scores and changes in three DLQI domain scores (daily activities, leisure activities, and symptoms/feelings). The initial (baseline to week 12) and sustained (week > 12 to week 52) treatment exposures were analysed by population type (total, PsO only, and PsO with comorbid PsA) and treatment arm (secukinumab, etanercept, or placebo).

RESULTS

Among the total population (N = 2401), PASI change was positively correlated with change in each assessed DLQI domain; correlations were weak to moderate over the initial treatment exposure period (β range, 0.20-0.29; all P < 0.001) and moderate to strong over the sustained exposure period (β range, 0.63-0.69; all P < 0.001). Similar trends were observed regardless of the presence of comorbid PsA. These relationships were confirmed among patients treated with secukinumab, etanercept, or placebo.

CONCLUSIONS

Improvements in PASI scores were directly moderately related to improvements in DLQI domain scores from initiation of treatment and extended over time, regardless of presence of comorbid PsA or treatment received.

Systematic review and practical guidance on the use of topical calcipotriol and topical calcipotriol with betamethasone dipropionate as long-term therapy for mild-to-moderate plaque psoriasis

While many patients with psoriasis are candidates for topical agents, long-term treatment effects are unclear. This systematic review evaluated global findings from clinical trials and real-world studies of topical calcipotriol and the two-compound formulation of calcipotriol and betamethasone dipropionate for mild-to-moderate plaque psoriasis (including scalp psoriasis). PubMed, Embase and MEDLINE were searched for relevant English-language publications along with Chinese, Japanese, Korean and Latin American publication databases. Identified articles were screened by title and abstract against predefined inclusion/exclusion criteria. A narrative synthesis of key efficacy and safety findings from the full papers of selected publications was developed. Thirty-seven relevant papers were identified (25 English, 11 Chinese and one Japanese-language study) including 28 randomized controlled trials. While there was significant heterogeneity in study length, treatment intensity and clinical measures, following a critical review of the published data combined with expert opinion, the following clinical practice recommendations were agreed in order to assist healthcare providers: in adults, long-term treatment with calcipotriol/betamethasone dipropionate is well tolerated and efficacious for up to 1 year on an 'as needed' basis, and for up to 16 weeks on a fixed-treatment regimen. Calcipotriol is also well tolerated and efficacious when used long term (up to 52 weeks) 'as needed' and for up to 20 weeks on a fixed-treatment regimen. Used on an 'as needed' basis for up to 1 year, the safety and efficacy profile of fixed-dose combination calcipotriol/betamethasone dipropionate is more favorable than calcipotriol alone; regular consultation between patients and their dermatologist/primary care physician is required to review psoriasis symptoms and adjust treatment accordingly; a specific treatment goal should be agreed on initiation of topical agent(s) to determine when long-term treatment can begin or if a regimen change is warranted; and application frequency during the continued treatment phase should consider the patients' treatment expectations and goals.

Dermatology Life Quality Index in Patients with Moderate-to-Severe Plaque Psoriasis Treated with Brodalumab or Ustekinumab

Introduction

Targeted biological therapies for psoriasis have resulted in significant benefits, with therapeutic goals such as clear or almost clear skin accompanied by improvements in health-related quality of life (HRQoL). The objective of this study was to compare the effects of 52 weeks of treatment with brodalumab or ustekinumab on HRQoL in patients with moderate-to-severe plaque psoriasis.

Methods

Data were pooled from two randomised controlled phase 3 trials (AMAGINE-2 and -3) which included patients with moderate-to-severe plaque psoriasis treated with brodalumab 210 mg or ustekinumab 45 or 90 mg for 52 weeks. HRQoL outcomes were measured using the Dermatology Life Quality Index (DLQI) as well as the DLQI-Relevant (DLQI-R) version which excludes ‘not relevant’ responses.

Results

A total of 929 patients were included, 339 in the brodalumab group and 590 in the ustekinumab group. A significantly greater reduction (improvement) in DLQI score from baseline was observed in the brodalumab group compared with the ustekinumab group at weeks 4 [least-squares (LS) mean difference − 2.9, 95% confidence interval [CI] − 3.6 to  − 2.2; p < 0.001), 12 (LS mean difference − 0.85, 95% CI − 1.5 to − 0.2; p = 0.01) and 52 (LS mean difference − 0.94, 95% CI − 1.6 to − 0.2; p = 0.009)]. Significantly greater proportions of patients treated with brodalumab achieved a DLQI score of 0 at weeks 4 (15.0 vs. 5.4%; p < 0.0001), 12 (37.5 vs. 28.0%; p = 0.0140) and 52 (46.3 vs. 30.3%; p < 0.0001), or of ≤ 1 [DLQI (0/1): 33.9 vs. 15.4%, 59.9 vs. 45.6% and 54.9 vs. 39.8%, respectively; all p < 0.0001]. Similar results were observed using the DLQI-R scoring system. Significantly more patients achieved a ≥ 4 or ≥ 5 improvement in DLQI with brodalumab compared to ustekinumab at weeks 4 and 52. Treatment with brodalumab was associated with significantly more patients achieving a DLQI of 0 compared to ustekinumab for all domains after 4 and 52 weeks.

Conclusion

Brodalumab was associated with a significantly greater improvement in HRQoL compared to ustekinumab in patients with moderate-to-severe psoriasis.

Comparative Efficacy and Relative Ranking of Biologics and Oral Therapies for Moderate-to-Severe Plaque Psoriasis: A Network Meta-analysis

INTRODUCTION

The clinical benefits of biologic and oral treatments for moderate-to-severe plaque psoriasis are well-established, but efficacy outcomes can vary across therapies. Comparative efficacy analysis can be highly informative in clinical settings with multiple therapeutic options. This study assessed the short-term and long-term comparative efficacy of biologic and oral treatments for moderate-to-severe psoriasis.

METHODS

A systematic literature review identified phase 2/3/4 randomized controlled trials (RCTs) through to 1 July 2020 for Food and Drug Administration- or European Medicines Agency-licensed treatments for moderate-to-severe psoriasis. Psoriasis Area and Severity Index (PASI) 75/90/100 response rates at the end of the primary response (short-term: 10-16 weeks from baseline) and maintenance periods (long-term: 48-52 weeks from baseline) were estimated using Bayesian network meta-analysis. Surfaces under the cumulative ranking curves (SUCRA) were estimated to present the relative ranking of treatments.

RESULTS

In the short term (N = 71 RCTs), the PASI 90 response rates were highest for ixekizumab (72.9%, SUCRA 0.951), risankizumab (72.5%, 0.940), and brodalumab (72.0%, 0.930), which were significantly higher than those for guselkumab (65.0%, 0.795), secukinumab (65.0%, 0.794), infliximab (56.8%, 0.702), certolizumab (400 mg: 49.6%, 0.607; 200 mg: 42.2%, 0.389), ustekinumab (90 mg: 47.9%, 0.568; weight-based: 45.7%, 0.505; 45 mg: 44.6%, 0.460), adalimumab (43.0%, 0.410), tildrakizumab (200 mg: 39.7%, 0.327; 100 mg: 37.2%, 0.268), etanercept (18.0%, 0.171), apremilast (12.4%, 0.090), and dimethyl fumarate (12.2%, 0.092). The PASI 100 response rates were highest for ixekizumab (41.4%), risankizumab (40.8%), and brodalumab (40.3%). In the long term (N = 11 RCTs), the PASI 90 rate was highest for risankizumab (85.3%, SUCRA: 0.998), which were significantly higher than those for brodalumab (78.8%, 0.786), guselkumab (78.1%, 0.760), ixekizumab (72.1%, 0.577), secukinumab (67.0%, 0.450), ustekinumab (weight-based: 55.0%, 0.252), adalimumab (51.6%, 0.176), and etanercept (37.9%, 0.001). Risankizumab had the highest PASI 100 response rate (65.4%), followed by brodalumab (55.7%) and guselkumab (54.8%).

CONCLUSIONS

Ixekizumab, risankizumab, and brodalumab had the highest short-term efficacy, and risankizumab had the highest long-term efficacy.

Modeling the optimal sequence of biologic therapies in plaque psoriasis in Spain

AIM

The purpose of this manuscript was to illustrate the impact of the place in the treatment sequence on the cost and cost-effectiveness of different biologics for patients with moderate-to-severe plaque psoriasis.

MATERIALS AND METHODS

We developed a treatment sequence model and focused on seven different biological treatment options and 840 combinations of treatment sequences. The model converted cost of treatment to a cost per responder by dividing treatment cost by expected number of patients achieving PASI100 after 52 weeks of treatment. We used Spanish ex-factory price levels, dosing recommendations and real-world data on drug survival to calculate the treatment costs.

RESULTS

The most cost-effective treatment sequence was brodalumab-risankizumab-guselkumab-ixekizumab, with a cost per responder of €139,281 during the first five years of treatment. In comparison, if brodalumab was not recommended as first-line therapy, total costs would increase by 7.4% to €149,616. If brodalumab was not recommended as any of the first four lines of treatment, total costs would increase by 13.1% to €157,527 relative to the most cost-effective treatment sequence.

CONCLUSIONS

A sequential therapy model may improve efficiency in the treatment of psoriasis. According to our results, brodalumab as the first-line therapy in Spain leads to the most cost-effective treatment sequence.

Cost per cumulative clinical benefit of biologic therapies for patients with plaque psoriasis: a systematic review

BACKGROUND: Measuring cumulative clinical treatment benefit over time captures speed and magnitude of effects. Assessing the cost of biologics relative to their cumulative clinical benefits versus a single time point represents an alternative to evaluate the value of a given biologic used to treat psoriasis. OBJECTIVE: To compare cumulative benefit and cost per cumulative benefit of biologics in treatment of moderate to severe psoriasis from a network meta-analysis (NMA). METHODS: Biologics included in the analysis were ixekizumab, adalimumab, guselkumab, ustekinumab, secukinumab, risankizumab, and certolizumab pegol. Psoriasis Area and Severity Index (PASI) responses over the initial 16-week treatment period were obtained from 31 articles. Cumulative benefits for PASI 75, PASI 90, and PASI 100 responses were measured as area under the curve (AUC) using the trapezoidal method. Bayesian-based NMA modeled percent maximum AUC through week 16 (%Max_AUCW16). The AUC estimates over 16 weeks were converted to total skin clearance threshold days achieved for PASI 75, PASI 90, and PASI 100 with each biologic. Cost per cumulative benefit was estimated by multiplying number of doses (per FDA label) by nationally representative discounted wholesale acquisition costs (WACs) for 16 weeks of treatment divided by %Max_AUCW16. The primary cost analysis used WACs, including week 16 doses. Co-primary cost analysis used discounted WACs, including week 16 doses. Sensitivity analysis was conducted using WACs and discounted WACs, excluding doses administered at week 16. RESULTS: Among biologics with available week 16 AUC data for PASI 90 and PASI 100, cumulative benefits over the initial 16-week treatment period ranged from 20.2% (certolizumab pegol) to 47.0% (ixekizumab) for PASI 90 and from 7.4% (adalimumab) to 22.2% (ixekizumab) for PASI 100. The total number of estimated PASI 90 and PASI 100 days achieved over the first 16 weeks of treatment was highest with ixekizumab (53 days and 25 days, respectively). In the primary analysis, guselkumab had the lowest cost per cumulative benefit (95% credible interval [CrI]; $99,742 [$89,941-$111,653]), followed by ixekizumab ($108,906 [$95,928-$126,093]) and adalimumab ($111,233 [$97,549-$129,022]) for PASI 90, and ixekizumab had the lowest cost per cumulative benefit ($230,884 [$191,611-$291,115]), followed by secukinumab ($238,945 [$204,029-$288,072]) and risankizumab ($279,968 [$250,683-$316,872]) for PASI 100 responses. In the co-primary analysis, ixekizumab had the lowest discounted cost per AUC (95% CrI; $60,988 [$53,719-$70,612]), followed by guselkumab ($66,827 [$60,260-$74,807]) and secukinumab ($69,622 [$61,783-$79,786]) for PASI 90, and ixekizumab had the lowest cost per cumulative benefit ($129,295 [$107,302-$163,024]), followed by secukinumab ($148,146 [$126,498-$178,605]) and guselkumab ($188,190 [$166,791-$215,969]) for PASI 100 responses. Conclusions: Among biologics studied, ixekizumab demonstrated the greatest cumulative clinical benefit, maintaining the lowest cost per cumulative benefit for PASI 100 responses and lowest discounted cost per cumulative benefit for PASI 90 and PASI 100 responses for moderate to severe psoriasis over the initial 16-week treatment period.

'Treat to Target' in Mild to Moderate Ulcerative Colitis: Evidence to Support this Strategy

BACKGROUND

The management of chronic conditions, above all rheumatic disease and diabetes, now incorporates a "treat to target" strategy where treatment aims to achieve objective outcomes. This is applicable in ulcerative colitis (UC) as well. Targets are demonstrated to prevent endorgan dysfunction, specifically bowel damage and its complications, and lastly colorectal cancer. Recently, the scientific community has tried to define further targets beyond those currently recommended, namely mucosal healing and clinical remission. Studies that prospectively investigated this approach in UC are scanty and a treat-to-target (T2T) algorithm is not routinely used in daily clinical practice.

OBJECTIVE

We aim to review current evidence on T2T in UC and discuss its adoption in routine clinical practice as well as in clinical trials.

METHODS

A PubMed search was conducted in February 2020 to identify published papers investigating targets' achievement rates in UC.

RESULTS

Different targets can be achieved through approved drugs for mild to moderate UC; histological remission is emerging as a robust target with respect to long-term outcomes.

CONCLUSION

Further studies to compare a T2T strategy with the traditional care are needed, particularly in the mild to moderate spectrum of disease.

Biologic drug survival rates in the era of anti-interleukin-17 antibodies: a time-period-adjusted registry analysis

Background

Drug survival rates reflect efficacy and safety and may be influenced by the availability of alternative treatment options. Little is known about time‐dependent drug survival in psoriasis and the effect of increasing numbers of biologic treatment options.

Objectives

To determine whether drug survival is influenced by the availability of treatment options and by factors such as gender, psoriatic arthritis or previous biologic treatment.

Methods

This observational, retrospective, multicentre cohort study analysed data from patients registered in the Austrian Psoriasis Registry (PsoRA) who were treated with biologics between 1 January 2015 and 30 November 2019.

Results

A total of 1572 patients who received 1848 treatment cycles were included in this analysis. The highest long‐term Psoriasis Area and Severity Index improvement was observed after treatment with ixekizumab, followed by ustekinumab and secukinumab, adalimumab and etanercept. Overall, ustekinumab surpassed all other biologics in drug survival up to 48 months. However, when adjusted for biologic naïvety, its superiority vanished and drug survival rates were similar for ixekizumab (91·6%), secukinumab (90·2%) and ustekinumab (92·8%), all of them superior to adalimumab (76·5%) and etanercept (71·9%) at 12 months and beyond. Besides biologic non‐naïvety (2·10, P < 0·001), the introduction of a new drug such as secukinumab or ixekizumab (relative hazard ratio 1·6, P = 0·001) and female gender (1·50, P = 0·019) increased the risk of treatment discontinuation overall, whereas psoriatic arthritis did not (1·12, P = 0·21).

Conclusions

The time‐dependent availability of drugs should be considered when analysing and comparing drug survival. Previous biologic exposure significantly influences drug survival. Women are more likely to stop treatment.

What is already known about this topic?

Female gender and previous biologic exposure have been discussed as predictors for decreased drug survival in patients with psoriasis, but it remains unknown whether a time‐dependent increased availability of treatment options alters biologic drug survival.

What does this study add?

The increased availability of alternative biologic treatments over time leads to an elevated risk for treatment discontinuation overall; therefore, drug survival analysis has to be time adjusted.

Moreover, the study reveals that the impact of previous biologic treatment on drug survival is tremendous and confirms worse drug survival in female patients.

Disease response and patient-reported outcomes among initiators of ixekizumab

OBJECTIVES

There is limited real-world evidence on using ixekizumab in psoriasis patients. Therefore, we characterized patients with psoriasis initiating ixekizumab and report 6-month changes in disease and patient-reported outcomes.

METHODS

Adult patients with psoriasis who initiated ixekizumab and completed a 6-month follow-up visit were enrolled from the Corrona Psoriasis Registry. Disease characteristics and outcomes were assessed at ixekizumab initiation. Outcomes included the mean 6-month change in Psoriasis Area and Severity Index (PASI), body surface area (BSA), Investigator Global Assessment (IGA), and IGA*BSA.

RESULTS

From baseline to follow-up in all patients (n = 136), means decreased for IGA*BSA (-45.5) and BSA (-12.4), and a higher % achieved an absolute PASI ≤ 5 (84.6%), BSA 0-3 (72.1%), and IGA 0/1 (50.7%). Within stratified groups, means decreased for PASI <12 for IGA*BSA (-21.1) and BSA (-6.3); PASI≥12 for IGA*BSA (-94.8) and BSA (-24.6); weight <100 kg for IGA*BSA (-45.1) and BSA (-12.4); weight ≥100 kg for IGA*BSA (-46.2) and BSA (-12.3); concomitant PsA for IGA*BSA (-56.0) and BSA (-15.3); and in no concomitant PsA for IGA*BSA (-36.9) and BSA (-10.0).

CONCLUSIONS

We provide real-world evidence on the benefits of ixekizumab for treating psoriasis, regardless of baseline disease severity, weight, or concomitant PsA.

Maintenance of Response Through up to 4 Years of Continuous Guselkumab Treatment of Psoriasis in the VOYAGE 2 Phase 3 Study

BACKGROUND

Guselkumab effectively treats moderate-to-severe psoriasis.

OBJECTIVES

Results of continuous guselkumab treatment through 4 years from VOYAGE 2 are presented.

METHODS

At baseline, 992 patients were randomized to receive guselkumab 100 mg every 8 weeks, placebo, or adalimumab 40 mg every 2 weeks. Placebo-treated patients crossed over to guselkumab at week 16. Weeks 28-76 incorporated randomized withdrawal, and all patients received open-label guselkumab through to week 204. Efficacy was analyzed using pre-specified treatment failure rules (patients were considered nonresponders after discontinuing due to lack of efficacy, worsening of psoriasis, or use of a prohibited treatment). There was no missing data imputation after treatment failure rules. Safety was analyzed through 4 years.

RESULTS

The proportions of guselkumab-treated patients who achieved and maintained designated clinical responses at weeks 100 and 204, respectively, were as follows: at least a 75% improvement in Psoriasis Area and Severity Index from baseline (PASI 75): 94.1% and 92.3%; PASI 90: 79.1% and 79.7%; PASI 100: 48.4% and 51.0%; Investigator's Global Assessment (IGA) score of 0/1: 83.1% and 81.9%; IGA score of 0: 52.7% and 52.7%; Dermatology Life Quality Index score of 0/1: 70.2% and 69.1%; Psoriasis Symptoms and Signs Diary (PSSD) symptom score of 0: 35.7% and 39.7%; PSSD sign score of 0: 22.0% and 27.2%; ≥ 5% improvement in Short Form-36 (SF-36) physical component score: 48.8% and 45.0%; ≥ 5% improvement in SF-36 mental component score: 45.1% and 43.2%; Hospital Anxiety and Depression Score (HADS)-anxiety score ≥ 8: 22.9% and 21.7%; and HADS-depression score ≥ 8: 16.6% and 21.0%. Similar findings were reported for the adalimumab → guselkumab group. No new safety signals were identified.

CONCLUSIONS

High efficacy levels were maintained from week 100 through to week 204 with continuous guselkumab treatment, across multiple endpoints, in VOYAGE 2. Guselkumab was well tolerated.

PSO-LONG: Design of a Novel, 12-Month Clinical Trial of Topical, Proactive Maintenance with Twice-Weekly Cal/BD Foam in Psoriasis

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.

Methods to improve quality of life, beyond medicines. Position statement of the European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes

The pharmaceutical approach to skin disease has been hugely successful, but despite effective drugs being available and used, there are still vast numbers of people who continue to have some level of persisting skin disease and continue to experience quality of life (QoL) impairment. So the question that needs to be answered, while we await further advances in our drug-based armamentarium, is how can we improve patients' QoL, beyond drugs? A working group was formed from members of the EADV Task Force on QoL and Patient Oriented Outcomes. Participants were asked to suggest all the ways in which they considered patients' QoL may be improved beyond medicines. Four groups of management approaches that may improve QoL in dermatology were identified: interventions within the dermatology service (hospitalization, multidisciplinary teams, patch testing and establishing relevant allergens and education), external services (corrective make-up, climatotherapy and balneotherapy), psychological (psychological intervention, cognitive therapy, hypnosis), lifestyle (lifestyle behavioural changes, religion and spirituality and music). The ultimate aim of therapy is to eradicate a disease in an individual and return the person's life to normal. But until the day comes when this has been achieved for every skin disease and for every patient there will be a need to support and assist many patients in additional non-pharmaceutical ways. These 'adjuvant' approaches receive too little attention while dermatologists and researchers strive for better pharmacological therapy. The different ways in which patients may benefit have been reviewed in our paper, but the reality is that most have a very poor evidence base. The research challenges that we have to meet are to identify those approaches that might be of value and to provide evidence for their optimal use. In the meantime, clinicians should consider the use of these approaches where QoL remains impaired despite optimal use of standard therapy.

Adjunctive Use of Calcipotriene/Betamethasone Dipropionate Foam in a Real-World Setting Curtails the Cost of Biologics Without Reducing Efficacy in Psoriasis

Introduction

Although the efficacy of monotherapy with biologics for psoriasis is well established, many patients fail to achieve complete plaque clearance from their initial biologic treatment alone. Adjunctive treatment with topical calcipotriene plus betamethasone dipropionate (Cal/BD) foam may offer substantial clinical benefit and potential cost savings.

Methods

We conducted a 16-week, open-label, single-arm study of adjunctive therapy with Cal/BD foam in subjects who had been treated with etanercept or adalimumab for ≥ 24 weeks but had not obtained a satisfactory treatment response. Assessments included affected body surface area (BSA), Physician’s Global Assessment (PGA) of disease severity, BSA × PGA, National Psoriasis Foundation (NPF) Treat to Target status, and likelihood of the physician to switch biologics. In parallel, a cost analysis was performed to compare the cost of switching to a different biologic versus adding Cal/BD foam to the original biologic.

Results

Four weeks of daily adjunctive treatment with Cal/BD foam led to notable reductions in BSA, PGA, and BSA × PGA relative to baseline. Additionally, by week 4, > 75% of subjects achieved NPF Treat to Target status, and the likelihood of the investigator to switch biologics decreased from 90.0% at baseline to 7.1%. The improved efficacy was maintained throughout the additional 12 weeks of maintenance Cal/BD foam application. The pharmacoeconomic evaluation demonstrated that adjuvant use of Cal/BD foam led to cost savings compared with switching biologic treatments.

Limitations

Due to the nature of the open-label study lacking a vehicle-treated control, no statistical comparison can be made.

Conclusions

The results of this study demonstrate that the addition of Cal/BD foam to plaque psoriasis patients who still have significant disease activity despite being on stable biologic therapy improves treatment outcomes to the point where switching to a more expensive biologic therapy is a less suitable treatment option.

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

Background

Certolizumab pegol (CZP) is an Fc‐free, PEGylated anti‐tumour necrosis factor biologic.

Objectives

To report the 3‐year efficacy of CZP in plaque psoriasis, pooled from the CIMPASI‐1 (NCT02326298) and CIMPASI‐2 (NCT02326272) phase III trials.

Methods

Adults with moderate‐to‐severe psoriasis for ≥ 6 months were randomized 2 : 2 : 1 to CZP 200 mg, CZP 400 mg or placebo, every 2 weeks (Q2W) for up to 48 weeks. Patients entering the open‐label period (weeks 48–144) from double‐blinded CZP initially received CZP 200 mg Q2W. Patients not achieving ≥ 50% improvement in Psoriasis Area and Severity Index (PASI 50) at week 16 entered an open‐label CZP 400 mg Q2W escape arm (weeks 16–144). Dose adjustments based on PASI response were permitted during open‐label treatment. Outcomes included PASI 75, PASI 90 and Physician’s Global Assessment (PGA) 0/1 responder rates, based on a logistic regression model (missing data imputed using Markov Chain Monte Carlo methodology).

Results

In total, 186 patients were randomized to CZP 200 mg Q2W and 175 to CZP 400 mg Q2W. At week 48, PASI 75/90 was achieved by 72·7%/51·3% of patients randomized to CZP 200 mg and 84·4%/62·7% randomized to CZP 400 mg. Patients entering the open‐label period at week 48, from blinded treatment, received CZP 200 mg Q2W. At week 144, PASI 75/90 was achieved by 70·6%/48·7% patients randomized to CZP 200 mg and 72·9%/42·7% randomized to CZP 400 mg. At week 16, 72 placebo‐randomized patients entered the CZP 400 mg Q2W escape arm; 75.7%/58.5% achieved PASI 75/90 at week 144.

Conclusions

Both CZP 200 mg and 400 mg Q2W demonstrated sustained, durable efficacy, with numerically higher responses for some outcomes with 400 mg Q2W.

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.

Efficacy data from the first 48 weeks of phase III trials have shown significant improvements in the signs and symptoms of psoriasis with certolizumab pegol dosed at either 400 mg or 200 mg every 2 weeks.

Numerically greater improvements were observed for patients treated with the higher dose.

What does this study add?

Plaque psoriasis is a chronic, systemic disease that requires long‐term management and sustained efficacy of therapies.

Three‐year efficacy data pooled from the CIMPASI‐1 and CIMPASI‐2 phase III trials demonstrate a sustained and durable response to certolizumab pegol dosed at either 400 mg or 200 mg every 2 weeks.

Additional long‐term clinical benefits may be obtained from the higher dose.

Treat to target or 'treat to clear' in inflammatory bowel diseases: one step further?

INTRODUCTION

Inflammatory bowel diseases (IBD) are chronic and progressive diseases. Long-term complications are demolitive surgery and colon-rectal cancer. A 'treat to target' strategy, in which the treatment aims to achieve objective outcomes, has already been introduced in the management of chronic conditions as rheumatic diseases. This approach is emerging as suitable for ulcerative colitis and Crohn's disease. Targets are predefined therapeutic goals demonstrated to prevent end-organ dysfunction. An optimization or switch of therapy is considered depending on the target's achievement, with regular monitoring.

AREAS COVERED

According to the Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) indications, mucosal healing and clinical remission are the main targets in IBDs. Histological remission is increasingly being considered as a novel target and has given rise to the new concept of 'disease clearance' which includes clinical, endoscopic and microscopic remission. We aim to review current evidence on the treat-to-target strategy in comparison to a stricter treat-to-clear in the IBD field.

EXPERT OPINION

Prospective studies on treat-to-target algorithm are sparse; a treat-to-clear approach is desirable but far from adoption in the daily practice and clinical trials. The ultimate goals of a treat-to-clear strategy differ in UC and in CD, including histological healing and transmural healing, respectively.

Spotlight on Topical Long-Term Management of Plaque Psoriasis

During the 28th Congress of the European Academy of Dermatology and Venereology (EADV) held in Madrid in October 2019, an industry hub was dedicated to the long-term management of psoriasis. Psoriasis is a systemic inflammatory disease primarily involving the skin that affects up to 4% of the European population, the majority of whom present with chronic plaque psoriasis. Topical therapies are well established in the first-line treatment of psoriatic plaque flares. Nevertheless, as psoriasis is a chronic disease, long-term control should be considered. The aim of the session was to provide expert opinion on the benefit of long-term maintenance therapy in chronic plaque psoriasis and introduce the concept of pro-active management to decrease the number of relapses and improve patient quality of life. The current guidelines and recommendations were reviewed, as well as the available data on published clinical trials. There is still an important role for topical therapy in psoriasis and current recommendations suggest a maintenance regimen for psoriasis. Adherence optimization and proactive management of relapse can be key factors for obtaining clinical outcomes in topical long-term therapy. Calcipotriol/betamethasone dipropionate foam is the only topical formulation with long-term data as a twice-weekly proactive treatment approach for up to 52 weeks for chronic plaque psoriasis.
