Management of Moderate to Severe Plaque Psoriasis with Brodalumab in Daily Practice: Real-World Evidence from the LIBERO Study in the Czech Republic

INTRODUCTION

Psoriasis is a chronic, immune-mediated inflammatory skin disease. Despite the availability of several therapies, many patients affected by this disease remain untreated, do not have adequate response, or suffer from treatment-related toxic effects. It has been shown that the interleukin (IL)-17 pathway plays a key role in the immunopathogenesis of psoriasis. Brodalumab, the first human monoclonal IgG2 antibody that selectively binds to subunit A of the human IL-17 receptor, blocking interactions with a number of cytokines of the IL-17 family, has confirmed fast onset of action, high complete clearance rates, and sustained efficacy. Nevertheless, there is only a limited amount of published real-world evidence (RWE) data.

METHODS

This was an open-label, multicenter, real-world, prospective, non-interventional, non-controlled (single-arm) observational study (LIBERO-CZ) assessing the management of moderate to severe psoriasis with brodalumab in daily practice for up to 52 weeks of treatment.

RESULTS

Fifty-four patients (70.4% male, mean age 46.9 ± 13.4 years, weight 95.6 ± 22.7 kg, disease duration 18.6 ± 12.7 years) were enrolled and included in the final analysis. Forty-nine of the patients completed the study and five discontinued prematurely; 51.8% of all the enrolled patients were biologic-naïve. At baseline, 28% patients were classified as severe (psoriasis area severity index (PASI) ≥ 20). Overall, the mean PASI decreased by 15.6 from 16.1 (± 5.0) at baseline to 0.5 (± 1.2) at the last visit. The primary endpoint of an absolute PASI ≤ 3 at week 12 (as observed analysis) was achieved by 95.9% of patients. The static Physician's Global Assessment (sPGA) success (defined as clear = 0 and almost clear = 1) at week 52 was achieved by 92.1% of patients. PASI 75, PASI 90, and PASI 100 were achieved by 98.0%, 87.8%, and 75.5% of patients, respectively, after approximately 52 weeks of treatment. The study also recorded very positive results concerning patient-reported outcomes.

CONCLUSIONS

LIBERO-CZ confirms the fast onset and high clearance rates of brodalumab in real life in both biologic-naïve and biologic-experienced patients.

Secukinumab demonstrates superiority over narrow-band ultraviolet B phototherapy in new-onset moderate to severe plaque psoriasis patients: Week 52 results from the STEPIn study

BACKGROUND

Biologic treatments have been studied mainly in patients with a long-term history of psoriasis and previous treatment failures.

OBJECTIVES

The purpose of this primary analysis of the STEPIn study is to determine whether early intervention with secukinumab in patients with new-onset moderate to severe plaque psoriasis is superior to standard of care treatment with narrow band ultraviolet B (nb-UVB) phototherapy.

METHODS

The STEPIn study is a randomized, open-label, multicentre study to investigate early intervention with 52 weeks of secukinumab 300 mg administered subcutaneously versus standard treatment with nb-UVB phototherapy in patients with new-onset (≤12 months) moderate to severe plaque psoriasis (NCT03020199). The primary and additional secondary endpoints were ≥90% improvement in Psoriasis Area and Severity Index (PASI 90) at Week 52 and Investigator's Global Assessment (IGA mod 2011) 0/1 response at Week 52, respectively.

RESULTS

In the secukinumab and nb-UVB study arms, 77/80 and 76/80 randomized patients received at least one dose of study treatment, respectively. The primary endpoint was achieved: 91.1% (70/77) of patients achieved a PASI 90 response at Week 52 in the secukinumab arm versus 42.3% (32/76) in the nb-UVB arm (p < 0.0001, odds ratio [OR] estimate [95% confidence intervals, CI] = 16.3 [5.6, 46.9]). The additional secondary endpoint was also achieved: 85.7% of patients achieved an IGA 0/1 response at Week 52 in the secukinumab arm versus 36.8% in the nb-UVB arm (p < 0.0001). The safety data were consistent with the safety profiles of secukinumab and nb-UVB with no new or unexpected safety signals.

CONCLUSIONS

Secukinumab was superior to nb-UVB in treating patients with new-onset moderate to severe plaque psoriasis. The high and sustained skin clearance observed indicates that biologic treatment for psoriasis may be more effective if used early in the disease course.

CITY-PSO: Prescribing behaviour of French private-practice dermatologists in psoriasis management: An observational, multicentre, cross-sectional study

BACKGROUND

Information regarding the prescribing behaviour of French private-practice dermatologists (PPDs) is scarce.

OBJECTIVES

First, to describe the population of PPDs involved in psoriasis management. Second, to describe the population of adult patients treated for psoriasis and their management.

METHODS

We published a call for participation targeting PPDs; we first asked respondents to complete a form regarding their prescribing behaviour, and then to include consecutive patients consulting for psoriasis during a one-month study period and to collect patient data.

RESULTS

The 94 participating PPDs included 1022 patients of mean age 52.9±17.9 years. The average body mass index was 28, and 25% had vascular comorbidities. Two thirds of patients had chronic psoriasis, for which 45% had consulted at least 5 times. Psoriasis was mostly with plaques (70.8%) and 11.4% of patients had psoriatic arthritis. The average body surface area (BSA) affected was 10.1%. Among the 679 patients without initial systemic treatment, 159 were started on systemic treatment. The main agents initiated were phototherapy (n=63), methotrexate (n=40), acitretin (n=30) and apremilast (n=20). In multivariate analysis, a higher BSA [Odds Ratio (OR) 1.10, 95% Confidence Interval (CI): 1.07-1.13; P<10^-4] and Dermatology Life Quality Index (DLQI) [OR 1.09, 95% CI: 1.03-1.15; P=0.04] were associated with prescription of systemic therapy at the end of the consultation.

CONCLUSION

The main limitation of our study was that participating PPDs were strongly involved in psoriasis management, which accounts for the high proportion of moderate-to-severe psoriasis and prescription of systemic treatments. Such committed PPDs and the development of psoriasis networks are key factors for improving the quality of care provided to psoriasis patients.

Demographic data, comorbidities, quality of life, and survival probability of biologic therapy associated with sex-specific differences in psoriasis in the Czech Republic

BIOREP is a Czech registry of patients with psoriasis undergoing biological treatment. The objective of the study was to compare differences in demographic data, previous therapy, comorbidities, severity of psoriasis, quality of life, drug survival rates, and reasons for discontinuation between men and women. We analyzed a cohort of patients from the registry treated between May 2005 and January 2020. The total study population of 2472 patients (4051 treatment series) included 913 females and 1559 males. Women were significantly older than men at the onset of the biological treatment (47.8 vs 45.4 years, P < .0012) and the mean durations of psoriasis and that from its diagnosis until initiation of biological therapy, were longer in women (29.6 vs 27.2 years and 23.2 vs 20.6 years, P < .0012). Women as compared with men were also more often diagnosed with psoriatic arthritis (43.5% vs 33.0%, P < .0012). The prevalence rate of comorbidities was equivalent for both sexes except for that of depression (11.4% females vs 3.7% males, P < .0012). Both the DLQI and PASI scores were significantly different at baseline (DLQI = 16.0 and PASI = 19.5 for men vs DLQI 17.6 = and PASI = 17.7 for women, P < .0012). The survival probability with biological therapy was significantly lower in women for both biologically naïve and non-naïve patients, and there was more evidence of adverse effects in women. Our research demonstrates significant differences relative to multiple factors associated with psoriasis between men and women.

Topical medications for chronic plaque psoriasis: A 3-year longitudinal study in France

Topical treatments are first-line therapies, prescribed to most patients with chronic plaque psoriasis. This non-interventional, longitudinal study examined data regarding the treatment pathways of French patients with psoriasis vulgaris using a pharmacy database. From this database, patients with an initial prescription of a topical treatment of interest (ie, calcipotriol alone and/or calcipotriol/betamethasone) between March and October 2013 were included in the study. The primary objective was to capture the switch from a topical treatment, from treatment initiation to receipt of a systemic therapy over a period of 3 years. A total of 26 605 patients were included in the study. The mean age was 58.5 years. The majority of patients (94.7%) maintained topical treatment during the 3 years, receiving a mean of 1.1 different therapies. Of 1400 patients who switched to a systemic therapy, 93.1% switched to a non-biological (mean time to switching >400 days), maintaining this for the remainder of the follow-up period. The most commonly prescribed first non-biological systemic therapy was methotrexate (37%). Less than 1% of patients switched to a biological therapy during follow up. Cohort analyses suggest that patients progressing to use of a systemic therapy within 12 months were those with more severe disease. There was a low rate of transition from topical to systemic therapies in patients with chronic plaque psoriasis during the first 3 years of treatment, suggesting stability of disease severity over time with topical therapy alone, potentially due to good patient adherence.

Complete clearance and psoriasis area and severity index response for brodalumab and ustekinumab in AMAGINE-2 and -3

BACKGROUND

Modern biologics achieve complete skin clearance [100% improvement in psoriasis area and severity index (PASI 100)] in 30-45% of psoriasis patients. Cumulative benefit considering rapidity, frequency and sustainability of response has not been thoroughly investigated.

OBJECTIVES

Compare the frequency, rapidity and sustainability of PASI 90 and 100 response in patients with moderate-to-severe psoriasis treated with brodalumab or ustekinumab.

METHODS

Integrated analyses of the brodalumab Phase III AMAGINE-2 (NCT01708603) and -3 (NCT01708629) trials were performed to determine proportion of patients achieving PASI response per visit; corresponding odds ratios (OR) were calculated. Cumulative clinical benefit of treatment was determined with area-under-the-curve (AUC) analysis. Cumulative incidence of response was analysed using a competing risk model of PASI response or rescue. Sustained response was evaluated by time to inadequate response using Kaplan-Meier methods. Proportion of time spent in different response states was descriptively analysed. Association between PASI response and health-related quality of life [Dermatology Life Quality Index (DLQI)] was assessed using data from all treatment groups from AMAGINE-1, -2 and -3.

RESULTS

A significantly higher proportion of patients treated with brodalumab achieved PASI 100 vs. ustekinumab (Week 52: 51% vs. 28%; OR [95% CI] 2.8 [2.1, 3.7]; P < 0.0001), with significant differences observed from Week 4. Cumulative benefit through 52 weeks was 69% higher with brodalumab (AUC ratio: 1.69; P < 0.001). Brodalumab patients were also significantly more likely to achieve a PASI 100 at least once over 52 weeks vs. ustekinumab (76% vs. 52%; P < 0.0001). Once response was achieved, brodalumab patients had a low likelihood of failure or need for rescue. There was significant positive association between PASI response level and DLQI0/1 achievement (P < 0.0001).

CONCLUSION

Brodalumab treatment resulted in significantly higher levels of skin clearance, longer sustained response and greater cumulative treatment benefit vs. ustekinumab.

Multidisciplinary approach to psoriasis in the Spanish National Health System: A social return on investment study

Introduction

Psoriasis is a chronic disease in which patients feel stigmatization, social rejection, and suffer from low self-esteem. There are still unmet needs that make it necessary to define a new multidisciplinary approach to provide benefits not only to patients and their families but also to the Spanish National Health System (SNHS) and society. The aim was to define a new approach to better address the unmet needs of patients with psoriasis within the SNHS and to measure its impact from a social perspective, that is, in clinical, health care, economic, and social terms.

Methods

Multidisciplinary experts identified, agreed on, and selected several health care interventions that were feasible for implementation in the SNHS. This process was carried out in four different areas: diagnosis, mild psoriasis, moderate psoriasis, and severe psoriasis. To estimate investment and social return, the social return on investment (SROI) method was used.

Results

The new approach to psoriasis management in the SNHS comprised 18 proposals. The investment needed for the implementation of this new approach would amount to €222.77 million and its return to €1,123.11 million. This would yield a SROI ratio of €5.04 for every euro invested.

Conclusion

The new approach to psoriasis management would yield a positive social return. The results will allow optimal strategic planning adapted to each assistance situation, to achieve a comprehensive and multidisciplinary approach.

Remission Duration and Long-Term Outcomes in Patients with Moderate-to-Severe Psoriasis Treated by Biologics or Tofacitinib in Controlled Clinical Trials: A 15-Year Single-Center Experience

INTRODUCTION

Relapse is common after treatment discontinuation for patients with moderate-to-severe psoriasis. The objective of this study was to understand the remission duration and long-term outcomes in psoriasis patients after biologic withdrawal.

METHODS

We retrospectively included the follow-up data of 184 patients with moderate-to-severe psoriasis after the end of 11 biologic or tofacitinib trials conducted between 2004 and 2016.

RESULTS

Among the 232 treatment courses, 95 achieved (psoriasis area and severity index) PASI 75 at the end of the studies. At 6 months after treatment discontinuation, the systemic treatment-free rates of our patients who entered the PRESTA, PRISTINE, PEARL, ERASURE, CLEAR, the global tofacitinib study, and the IXORA-P study were 66.7%, 66.7%, 75.0%, 16.7%, 22.2%, 33.3%, and 29.2%, respectively. Pooled data showed a serious adverse event incidence rate of 1.5/100 person-years. The proportions of systemic treatment-free episodes were 16.8%, 7.4%, 4.3%, 3.2%, and 3.2% at 1, 2, 3, 4, and 5 years, respectively. Biologics were reinitiated in 41.9%, 66.7%, 77.1%, 83.5%, and 86.1% at 1, 2, 3, 4, and 5 years, respectively. Multivariate generalized estimating equation (GEE) regression analysis demonstrated that predictors for a longer relapse-free duration were baseline PASI, PASI improvement, biologic naivety, and early biologic intervention. Patients who received early biologic intervention, who achieved PASI 90, and who were biologic naive showed significantly higher relapse-free rate by Kaplan-Meier analysis with log rank test.

CONCLUSIONS

Systemic treatment was required in 86.1% of patients within 12 months after biologic withdrawal and biologics were reinitiated in 77.1% of patients after 3 years. However, early biologic administration within 2 years after diagnosis demonstrated a lower risk of relapse in patients with moderate-to-severe psoriasis.

Compounded topical preparations in plaque psoriasis: Still a place for it in 2018?

Compounded topical preparations (CTP) were used to treat psoriasis until the last century and have disappeared from guidelines. The present authors report two severe psoriasis patients who were treated with CTP. A man had psoriasis with a PASI of 23 and a body surface area (BSA) of 43%. He had been using daily for several weeks a CTP including minoxidil, clobetasol propionate and hydroxyprogesterone formulated in an alcohol based vehicle. A woman suffered from psoriasis with an annular inflammatory pattern and a central healing. The PASI was 20 and the BSA was 30%. She had been using a CTP daily for 4 months including resorcinol, salicylic acid, 0.05% tretinoin cream, bethamethasone dipropionate cream. Until the 1970s, the dermatological textbooks recommended to treat severe psoriasis with CTP. Nowadays, CTP are considered outdated because of the large therapeutic armamentarium. The stability and benefit risks of the CTP used here were not documented. The use of CTP in psoriasis should be regulated and must be evidence based. Strict protocol and stability evaluation for preparations must be confirmed prior to compounding.

Trends in hospitalization rates for psoriasis flares since the introduction of biologics: a time series in France between 2005 and 2015

BACKGROUND

In the late 2000s, the introduction of biologics transformed the prognosis for patients with moderate-to-severe psoriasis. We hypothesized that treatment with biologics may associate with a reduction in the hospitalization rate for psoriasis flares.

OBJECTIVE

To analyse changes over time in the hospitalization rate for psoriasis flares.

METHODS

We included inpatient stays in any of nine French hospitals between 2005 and 2015 for a psoriasis flare, as documented in the national inpatient database. In two centres, we also analysed data from the individual patients' electronic medical records.

RESULTS

A total of 3572 stays were included. The introduction of biologics was not associated with a decrease in the number of hospitalizations for a psoriasis flare; on the contrary, we observed a non-significant increase in the number of hospitalizations (13 hospitalizations for psoriasis flares per quarter per 10 000 beds). In the two-centre study, the introduction of biologics was associated with a significant increase in the hospitalization of patients receiving topical treatments only (520 hospitalizations per year per 10 000 beds) and those with a first psoriasis flare.

CONCLUSION

The number of hospitalizations for a psoriasis flare tended to increase between 2005 and 2015. The availability of additional treatment options might have increased patient demand and/or broadened the indications in clinical practice.

Characteristics and risk profile of psoriasis patients included in the Czech national registry BIOREP and a comparison with other registries

BACKGROUND

BIOREP is a Czech registry of psoriatic patients on biological treatment in a clinical setting. We describe the characteristics of patients with psoriasis at the time of enrollment and present comparisons with published data from other national registries.

METHODS

We analyzed the cohort of patients treated with biologics between May 2005 and May 2015. Demographic data, previous therapies, comorbidities, and severity of psoriasis were compared with data from other registries - DERMBIO, BIOBADADERM, BADBIR, and PSOBEST.

RESULTS

A total of 1412 psoriatic patients initiating biological treatment were included with a predominance of males (63.4%). The mean patient age was 50.2 years, and approximately 70.5% of patients were either overweight or obese. The mean baseline Psoriasis Area and Severity Index was 19.8, and the Dermatology Life Quality Index was 16.6. More than one-third of patients (41.0%) reported a history of psoriatic arthritis, and a high proportion of patients (49.5%) with cardiovascular risk factors (hypertension [35.2%], hyperlipidemia [27.7%], diabetes mellitus [11.4%], coronary heart disease [4.9%], and obesity [15.2%]) were observed. Most of the patients had been previously treated with phototherapy (85.4%), acitretin (74.0%), methotrexate (65.7%), or cyclosporine (53.1%).

CONCLUSION

BIOREP is one of the first registries of patients with psoriasis treated with biologics in Central and Eastern Europe. Our results found a similar or higher prevalence of comorbidities, long disease duration, and high impact on the quality of life among patients included in Western European registries.

Quality of life and patient benefit following transition from methotrexate to ustekinumab in psoriasis

BACKGROUND

TRANSIT (NCT01059773) compared immediate and gradual transition from methotrexate to ustekinumab in psoriasis patients via multiple measures, including patient-reported outcomes.

OBJECTIVE

To evaluate patient perception of treatment benefits in TRANSIT.

METHODS

A total of 489 psoriasis patients received ustekinumab, with immediate cessation of methotrexate (Arm 1) or 4 weeks' overlap with decreasing methotrexate dose (Arm 2). Ustekinumab was administered at weeks 0, 4, 16, 28 and 40. Dermatology Life Quality Index (DLQI), EuroQol 5-item (EQ-5D), visual analogue scale (VAS) valuation technique and patient benefit index (PBI) were employed. Mean global PBI and sub-scores were calculated from the sum of the benefit items weighted by their respective relevance at baseline. Patient-relevant benefit was defined as PBI ≥1 (scale: 0 [no benefit] to 4 [maximum benefit]). Correlations of global PBI with Psoriasis Area and Severity Index (PASI) and DLQI were examined.

RESULTS

Relationships between PBI and clinical data were evaluable in 340 patients. The most important treatment goals at baseline included: 'be healed of all skin defects', 'have confidence in therapy', 'get better skin quickly' and 'regain control of the disease'. Benefit in PBI global score was achieved at week 4 by 93% of patients in Arm 1 and 91% in Arm 2. Global PBI scores increased in both Arms between weeks 4 and 52. Global PBI correlated weakly with PASI change from baseline (correlation coefficient range: -0.22 to -0.40), and moderately with DLQI (-0.29 to -0.54). Overall DLQI score was lower than baseline at all times; and the percentage of patients with an overall score of 0 or 1 increased with time. Correspondingly, EQ VAS scores increased with time. DLQI and EQ VAS results were similar between arms.

CONCLUSIONS

Regardless of the strategy for transitioning from methotrexate, ustekinumab was associated with rapid and sustained improvement in patient-reported outcomes. PBI appears a suitable tool for assessing patient-relevant treatment benefits in psoriasis patients.

A prospective phase III, randomized, double-blind, placebo-controlled study of brodalumab in patients with moderate-to-severe plaque psoriasis

BACKGROUND

The interleukin-17 cytokine family plays a central role in psoriasis pathogenesis.

OBJECTIVES

To evaluate the efficacy and safety of brodalumab, a human anti-interleukin-17 receptor antibody, in treating patients with moderate-to-severe plaque psoriasis.

METHODS

In this phase III, double-blind, placebo-controlled study (NCT01708590; AMAGINE-1), adult patients in the U.S.A., Canada and Europe were randomized to brodalumab (140 or 210 mg) or placebo every 2 weeks (Q2W), with an additional dose at week 1, for a 12-week induction phase. At week 12, patients receiving brodalumab who achieved static Physician's Global Assessment 0 or 1 (sPGA success) were rerandomized to the placebo or induction dose. After week 16, patients with sPGA ≥ 3 were re-treated with the induction dose. After ≥ 12 weeks of retreatment, patients with sPGA 2 for ≥ 4 weeks or sPGA ≥ 3 were rescued with brodalumab 210 mg Q2W. At week 12, patients randomized to brodalumab with sPGA ≥ 2 or placebo received brodalumab 210 mg Q2W. Coprimary end points were the percentage of patients with ≥ 75% improvement in Psoriasis Area and Severity Index score (PASI 75) and sPGA success at week 12.

RESULTS

There were 661 patients randomized: 220 placebo, 219 brodalumab 140 mg and 222 brodalumab 210 mg. At week 12, 60% (140 mg) and 83% (210 mg) vs. 3% (placebo) achieved PASI 75, and 54% (140 mg) and 76% (210 mg) vs. 1% (placebo) achieved sPGA success. The safety profile was considered acceptable.

CONCLUSIONS

Brodalumab therapy resulted in significant clinical benefit and an acceptable safety profile in patients with moderate-to-severe plaque psoriasis.

Tofacitinib versus etanercept or placebo in patients with moderate to severe chronic plaque psoriasis: patient-reported outcomes from a Phase 3 study

BACKGROUND

Tofacitinib is an oral Janus kinase inhibitor that is being investigated for psoriasis. Psoriasis impacts on physical and psychological well-being; improvements in health-related quality of life (HRQoL) with etanercept in psoriasis are well documented.

OBJECTIVE

To evaluate HRQoL with tofacitinib, vs. placebo or etanercept, in the Phase 3, randomized, placebo-controlled, non-inferiority, Oral-treatment Psoriasis Trial (OPT) Compare Study (NCT01241591).

METHODS

Adults with moderate to severe chronic plaque psoriasis were randomized 3:3:3:1 to tofacitinib 10 or 5 mg twice daily (BID), etanercept 50 mg twice weekly or placebo, for 12 weeks. Patient-reported outcomes (PROs) included Dermatology Life Quality Index (DLQI), Itch Severity Item and Patient Global Assessment of psoriasis.

RESULTS

At baseline, 83.4% (911/1092) of patients had a DLQI score ranging between 6 and 30, indicating a substantial burden of disease. By Week 12, 47.3%, 43.6% and 30.9% of patients in the tofacitinib 10 mg BID, etanercept and tofacitinib 5 mg BID groups, respectively, had a DLQI score of 0 or 1 (no effect of psoriasis on QoL) vs. 7.8% for placebo (all P < 0.0001). Tofacitinib significantly reduced itch vs. placebo (P < 0.05 both doses) and etanercept (P < 0.0001 both doses) within 1 day of starting treatment. Furthermore, reductions in itch were greater with tofacitinib 10 mg BID, vs. etanercept, at Weeks 2-12 (all time points P < 0.05). At Week 2, an Itch Severity Item score of 'little or no itch' was more frequent with tofacitinib 10 mg (68.6%) vs. etanercept (57.4%) and placebo (12.2%), and the PtGA response rate was significantly greater with tofacitinib 10 mg vs. placebo (P < 0.05).

CONCLUSION

Oral tofacitinib provided significant improvements across multiple PROs by Week 12. Improvements with tofacitinib 10 mg BID were comparable to etanercept, and improvements in itch were greater and more rapid with tofacitinib 10 mg BID.

Physician perspectives in the management of psoriasis and psoriatic arthritis: results from the population-based Multinational Assessment of Psoriasis and Psoriatic Arthritis survey

Background

Available literature on psoriasis and psoriatic arthritis (PsA) demonstrates a tremendous burden of disease and suggests underdiagnosis and undertreatment.

Objective

To obtain real‐world physician perspectives on the impact of psoriasis and PsA and its treatment on patients' daily lives, including perceptions of, and satisfaction with, current therapies.

Methods

The Multinational Assessment of Psoriasis and Psoriatic Arthritis (MAPP) surveyed dermatologists (n = 391) and rheumatologists (n = 390) in North America (Canada and the United States) and Europe (France, Germany, Italy, Spain and United Kingdom).

Results

Dermatologists classified 20.3% and 25.7% of their patients as having severe psoriasis and severe PsA respectively; rheumatologists indicated that 48.4% of their PsA patients had active disease. Of the psoriasis patients complaining of joint pain, only 33.0% had a diagnosis of PsA. An impact on daily activities or social/emotional well‐being was recognized by 57.2% to 79.3% of physicians. In patients with moderate‐to‐severe psoriasis, dermatologists reported 74.9% were receiving topical therapy, 19.5% conventional oral therapy and 19.6% biologics. Dermatologists and rheumatologists reported similar rates of topical (≈45%) and biologic (≈30%) therapy utilization for their PsA patients; conventional oral therapy was more often prescribed by rheumatologists (63.4%) vs. dermatologists (35.2%). Reasons for not initiating or maintaining systemic therapies were related to concerns about long‐term safety, tolerability, efficacy and costs (biologics).

Conclusion

Physicians in North America and Europe caring for patients with psoriasis and PsA acknowledge unmet treatment needs, largely concerning long‐term safety/tolerability and efficacy of currently available therapies; evidence suggests underdiagnosis of PsA and undertreatment of psoriasis among dermatologists.

Development and psychometric validation of the REFlective evaLuation of psoriasis Efficacy of Treatment and Severity (REFLETS) questionnaire: a common measure of plaque-type psoriasis severity and treatment efficacy for patients and clinicians

BACKGROUND

To date, there is no global consensus on the definition of the severity of psoriasis. The REFlective evaLuation of psoriasis Efficacy of Treatment and Severity (REFLETS) questionnaire has recently been developed to provide a better understanding of plaque-type psoriasis severity and treatment efficacy from both patient and clinician perspectives.

OBJECTIVE

This study aimed to develop and psychometrically validate the new REFLETS questionnaire to evaluate patient and clinician perceptions of plaque-type psoriasis severity and treatment efficacy.

METHODS

Two similar versions of the REFLETS questionnaire were developed following a rigorous methodology for clinicians and patients, referring to 'the psoriasis of your patient' or to 'your psoriasis', respectively. An observational, longitudinal, multicentre study was conducted in France with 34 dermatologists and 430 mild to severe plaque-type psoriasis patients to finalize the questionnaire and evaluate its psychometric properties.

RESULTS

Two dimensions were defined--severity and treatment efficacy--with three subdimensions within severity (impact of psoriasis, symptoms and disease course), and two individual items on joint pain. The questionnaire was well accepted by clinicians and patients. Excellent internal consistency (Cronbach's alpha = 0.66-0.98) and test-retest reliability (intraclass correlation coefficients = 0.83-0.94) were demonstrated. REFLETS scores were moderately to highly correlated to Psoriasis Area and Severity Index (r = 0.35-0.70), Skindex-29 (r = 0.46-0.82) and DLQI scores (r = 0.36-0.82). Patients with decreased psoriasis severity and those with increased treatment efficacy, according to patient global evaluations, had lower severity and higher treatment efficacy REFLETS scores, respectively.

CONCLUSION

REFlective evaLuation of psoriasis Efficacy of Treatment and Severity is a promising tool for assessing plaque-type psoriasis severity and treatment efficacy from patient and clinician perspectives. It may help to improve patient and clinician communication in treatment decision making.

Think beyond the Skin

Objective:

Explore the feasibility of Treat to Target in the area of psoriasis as seen in other therapeutic areas such as hypertension, hyperlipidemia, diabetes and rheumatoid arthritis.

Methods:

Review validated, measurable targets for psoriasis, including physician global assessment (PGA), psoriasis area and severity index (PASI) and dermatology life quality index (DLQI). Examine principles brought forth in the published European consensus on psoriasis and develop a Canadian consensus on Treat to Target in psoriasis.

Results:

As PASI and DLQI are not routinely used in the community setting, we are recommending target at a PGA of zero (clear).

Conclusion:

Recommend that the target is a PGA of zero (clear) as it provides a simple and measurable result that the patient and physician can clearly understand.

Barriers to the prescription of systemic therapies for moderate-to-severe psoriasis--a multinational cross-sectional study

Despite the availability of a plethora of approved systemic treatments, high proportions of patients with moderate-to-severe psoriasis do not receive systemic treatment. This study aims at identifying barriers that hinder dermatologists from prescribing systemic treatments for psoriasis. A cross-sectional online survey in six countries (Canada, Germany, Spain, France, Italy, UK) was performed among 300 dermatologists, assessing the relevance of 15 potential barriers towards prescribing acitretin, cyclosporine, methotrexate, adalimumab, etanercept, infliximab and ustekinumab. Multivariate regression analyses were used to explore provider characteristics related to these barriers. Treatment barriers are perceived differently in the countries investigated, with Spanish, Italian and Canadian dermatologists being particularly concerned about the safety of methotrexate and Canadian dermatologists about the safety of cyclosporine. In general, safety concerns were the most important barrier to the use of cyclosporine, (18 % of participants' moderate/9 % strong or very strong barrier). Costs were being perceived as a strong or very strong barrier to the use of the different biologics by 19-24 % of the participants. Overall, country and work place were the most important determinants of treatment barriers. Sex, age, training, position and experience were minor determinants of treatment barriers. Medical reasons such as safety concerns or an inappropriate risk-benefit profile are particularly relevant barriers to the prescription of conventional treatments; whereas for biological treatments, economic reasons such as costs are more prevalent. Country specific analysis showed national differences in the perception of safety. The treatment barriers identified in this exploratory study should be confirmed in further health services research.
