Tapinarof Cream 1% Once Daily: Significant Efficacy in the Treatment of Moderate to Severe Atopic Dermatitis in Adults and Children Down to 2 Years of Age in the Pivotal Phase 3 ADORING Trials

BACKGROUND

Tapinarof cream 1% once daily (QD), a topical aryl hydrocarbon receptor agonist, downregulates pro-inflammatory Th2 cytokines, upregulates skin-barrier components, and reduces oxidative stress.

OBJECTIVE

To assess tapinarof efficacy and safety in adults and children down to 2 years of age with atopic dermatitis (AD).

METHODS

813 patients were randomized to tapinarof or vehicle QD in two 8-week phase 3 trials.

RESULTS

The primary efficacy endpoint, Validated Investigator Global Assessment for Atopic DermatitisTM score of 0 or 1 and ≥2-grade improvement from baseline at Week 8, was met with statistical significance in both trials: 45.4% vs 13.9% and 46.4% vs 18.0% (tapinarof versus vehicle; both P<0.0001). Significantly superior EASI75 responses were also observed with tapinarof versus vehicle at Week 8: 55.8% vs 22.9% and 59.1% vs 21.2% (both P<0.0001). Rapid improvements in patient-reported pruritus were also significant with tapinarof versus vehicle. Common adverse events (≥5%) of folliculitis, headache, and nasopharyngitis were mostly mild or moderate, with lower discontinuations due to adverse events in the tapinarof groups than with vehicle.

LIMITATIONS

Long-term efficacy was not assessed.

CONCLUSION

Tapinarof demonstrated highly significant efficacy and favorable safety and tolerability in a diverse population of patients with AD down to 2 years of age.

Circulating Monocytes Are Predictive and Responsive in Moderate-to-Severe Plaque Psoriasis Subjects Treated with Apremilast

Monocytes play a critical role in the inflammation associated with psoriasis, and their abnormalities have been reported as biomarkers of cardiovascular event risk, a psoriasis comorbidity. Monocytic cells in chronic inflammatory disorders express elevated levels of cAMP phosphodiesterase. Restoring cAMP levels using the oral cAMP phosphodiesterase-4 inhibitor, apremilast, improves clinical outcomes for a subset of patients with psoriasis. We asked whether aberrant monocyte subsets or transcriptomic pathways can function as biomarkers of psoriasis endotypes that can predict enhanced clinical responses to cAMP phosphodiesterase inhibition. A 16-week open-label study of 22 patients with monocyte flow cytometric and transcriptomic analysis was performed. Subjects with elevated hyperadhesive monocyte doublets at baseline were more likely to be responders to apremilast (P < .0001); 82% of subjects with elevated hyperadhesive monocyte doublets achieved 50% reduction in PASI compared with 46% in those without elevated doublets. We observed a significant reduction in hyperadhesive monocyte-containing doublets and monocyte-platelet aggregates, suggesting an effect of apremilast on the adhesiveness of blood monocytes during chronic inflammation. Monocyte differentially expressed gene transcripts predictive of clinical response uncovered pharmacoendotypes with distinct patterns of nucleotide metabolism, energetics, and differentiation. Further study to understand the basis of drug responsiveness and to develop an apremilast psoriasis treatment algorithm using monocyte-refined gene expression is required to validate and become practical in clinical use, offering patients a test that personalizes their likelihood of clinical response.

The Efficacy and Safety of Bimekizumab for Plaque Psoriasis: An Expert Consensus Panel

INTRODUCTION

Psoriasis is a chronic inflammatory condition affecting the skin, joints, and several other organ systems with significant disease burden. Bimekizumab is the first monoclonal antibody targeting both interleukin (IL)-17A and interleukin-17F and has demonstrated efficacy for treating moderate to severe psoriasis. Limited guidelines exist for incorporating this drug into clinical practice. The purpose of this study was for a panel of experts in psoriasis management to synthesize current literature and provide consensus statements with guidance on use of bimekizumab.

METHODS

A comprehensive literature search of PubMed, Scopus, and Google Scholar was completed for English-language original research articles on the use of bimekizumab for moderate to severe psoriasis and psoriatic arthritis. A panel of nine dermatologists with significant expertise in treatment of psoriasis gathered to review the articles and create consensus statements on this new medication. A modified Delphi process was used to approve each statement and a strength of recommendation was assigned using Strength of Recommendation Taxonomy criteria.

RESULTS

The literature search produced 102 articles that met criteria. A thorough screening of the studies for relevance to the research question resulted in 19 articles. These were distributed to all panelists for review prior to a roundtable discussion. The panel unanimously voted to adopt 14 consensus statements and recommendations, 12 of which were given a strength of "A", one of which was given a strength of "B", and one of which was given a strength of "C".

CONCLUSION

Bimekizumab results in rapid and long-lasting clinical improvement for patients with moderate to severe plaque psoriasis and psoriatic arthritis. It has demonstrated superior efficacy when compared to several other biologics. The safety profile is consistent with other biologics, except for an increased incidence of oropharyngeal candidiasis.

Efficacy of Baricitinib in Patients with Various Degrees of Alopecia Areata Severity: Post-Hoc Analysis from BRAVE AA1 and BRAVE AA2

BACKGROUND

Baricitinib, an oral selective JAK1/JAK2 inhibitor, is approved for the treatment of adults with severe alopecia areata (AA).

OBJECTIVE

To evaluate differences in response up to week 52 among subgroups based on the baseline severity of AA assessed with the Severity of Alopecia Tool (SALT) score.

METHODS

Data were pooled from BRAVE-AA1 and BRAVE-AA2, two randomized, placebo-controlled, phase 3 trials, which enrolled adults with a SALT score ≥ 50. Patients were subdivided by the degree of AA severity at baseline.

RESULTS

Among the 855 patients treated with baricitinib 2 mg and 4 mg, improvements in scalp hair growth continued through to week 52. A superior response was observed in patients with a SALT score of 50-94 versus a score of 95-100. Patients on baricitinib 4 mg had a faster and higher response rate compared to baricitinib 2 mg.

CONCLUSION

Across all degrees of severity for baricitinib 2 mg and 4 mg doses, the proportion of patients responding was yet to plateau up to week 52. Response to treatment was longer for patients with a baseline SALT score 95-100. Further studies are needed to analyze other parameters that may impact observed response rates.

Equity in the usage of biologics for psoriasis in the working poor

Biologic therapy often produces excellent outcomes for psoriasis; however, their high cost may create a barrier to appropriate usage, especially in the working poor population. This study defines working poor as income below 150% of the federal poverty level and holding or seeking work at least half a year. Our study aims to identify gaps in access to biologic therapy for psoriasis based on working poor status. This retrospective cross-sectional study was conducted utilizing data from the Medical Expenditure Panel Survey (MEPS) from 2007 to 2018. Patients were stratified into working poor (57,091), non-working poor (43,421), and non-poor (693,841) groups for analysis. In univariate analysis, WP (4.0%, ph p = 0.003) and NWP (2.8%, ph p = 0.006) were less likely to use biologics than NP (15.8%) (X² p < 0.001). A binary logistic regression showed that WP vs. NP status (OR 0.27, p = 0.05), female vs. male sex (OR 0.55, p = 0.05), Black vs. White race (OR 0.14, p = 0.02), and Medicare vs. private insurance (OR 0.09, p = 0.03) had lower odds of using biologics. After correcting for age, sex, race, and insurance, WP confers an independent risk factor to lower biologic prescriptions. The high cost of biologics in the setting of financial barriers for some patients should be considered by physicians prescribing biologic therapy for psoriasis.

Efficacy and Safety of Topical Hypericin Photodynamic Therapy for Early-Stage Cutaneous T-Cell Lymphoma (Mycosis Fungoides): The FLASH Phase 3 Randomized Clinical Trial

Importance

Given that mycosis fungoides-cutaneous T-cell lymphoma (MF/CTCL) is chronic, there is a need for additional therapies with minimal short- and long-term adverse effects. Topical synthetic hypericin ointment, 0.25%, activated with visible light is a novel, nonmutagenic photodynamic therapy (PDT).

Objectives

To determine the efficacy and safety of topical synthetic hypericin ointment, 0.25%, activated with visible light as a nonmutagenic PDT in early-stage MF/CTCL.

Design, Settings, and Participants

This was a multicenter, placebo-controlled, double-blinded, phase 3 randomized clinical trial (FLASH study) conducted from December 2015 to November 2020 at 39 academic and community-based US medical centers. Participants were adults (≥18 years) with early-stage (IA-IIA) MF/CTCL.

Interventions

In cycle 1, patients were randomized 2:1 to receive hypericin or placebo to 3 index lesions twice weekly for 6 weeks. In cycle 2, all patients received the active drug for 6 weeks to index lesions. In cycle 3 (optional), both index and additional lesions received active drug for 6 weeks.

Main Outcomes and Measures

The primary end point was index lesion response rate (ILRR), defined as 50% or greater improvement in modified Composite Assessment of Index Lesion Severity (mCAILS) score from baseline after 6 weeks of therapy for cycle 1. For cycles 2 and 3, open label response rates were secondary end points. Adverse events (AEs) were assessed at each treatment visit, after each cycle, and then monthly for 6 months. Data analyses were performed on December 21, 2020.

Results

The study population comprised 169 patients (mean [SD] age, 58.4 [16.0] years; 96 [57.8%] men; 120 [72.3%] White individuals) with early-stage MF/CTCL. After 6 weeks of treatment, hypericin PDT was more effective than placebo (cycle 1 ILRR, 16% vs 4%; P = .04). The ILRR increased to 40% in patients who received 2 cycles of hypericin PDT (P < .001 vs cycle 1 hypericin) and to 49% after 3 cycles (P < .001 vs cycle 1 hypericin). Significant clinical responses were observed in both patch and plaque type lesions and were similar regardless of age, sex, race, stage IA vs IB, time since diagnosis, and number of prior therapies. The most common treatment-related AEs were mild local skin (13.5%-17.3% across cycles 1-3 vs 10.5% for placebo in cycle 1) and application-site reactions (3.2%-6.9% across cycles 1-3 vs 4% for placebo in cycle 1). No drug-related serious AEs occurred.

Conclusion and Relevance

The findings of this randomized clinical trial indicate that synthetic hypericin PDT is effective in early-stage patch and plaque MF/CTCL and has a favorable safety profile.

How Do Experts Treat Patients with Bullous Pemphigoid around the World? An International Survey

Many treatments are currently proposed for treating patients with bullous pemphigoid (BP). We assessed treatment modalities of BP depending on the different countries, BP extent, and patients' comorbidities. We surveyed worldwide experts about how they treat patients with BP. A total of 61 experts from 27 countries completed the survey. Severe and moderate BP were treated with oral prednisone (61.4 and 53.7%, respectively) or superpotent topical corticosteroids (CSs) (38.6 and 46.3%, respectively). Conventional immunosuppressants were more frequently combined with oral prednisone (74.5%) than with superpotent topical CS (37.5%) in severe BP. Topical CSs were mainly used in Europe in mild (81.1%), moderate (55.3%), and severe (54.3%) BP. In the United States of America and Asia, systemic CSs were mainly proposed for treating severe (77.8 and 100%, respectively), moderate (70 and 77.8%, respectively), and also mild (47.1 and 33.3%, respectively) BP. Most experts reduced the initial dose of oral CS in patients with diabetes mellitus (48.1%) or cardiac insufficiency (40.2%) but rarely changed BP treatment in patients with neurological disorders or neoplasia. This survey showed major differences in the way patients with BP are treated between AmeriPac countries (United State of America, Latin America, and Australia) and Asia on the one hand and Europe and the Middle East on the other hand.

Effect of Costimulatory Blockade With Abatacept After Ustekinumab Withdrawal in Patients With Moderate to Severe Plaque Psoriasis: The PAUSE Randomized Clinical Trial

Question

Does blockade of CD28/B7 costimulatory signaling with abatacept suppress the psoriasis molecular signature and prevent psoriasis relapse after ustekinumab withdrawal?

Findings

In this parallel-design, double-blind randomized clinical trial of 91 adults with moderate to severe plaque psoriasis, costimulatory blockade with abatacept did not prevent psoriasis relapse and did not maintain suppression of the pathogenic psoriasis molecular signature following ustekinumab withdrawal.

Meaning

In this study, abatacept did not prevent psoriasis relapse, which may rely on alternative, compensatory mechanisms of residual T-cell activation in skin.

Importance

Psoriasis relapse may involve compensatory T-cell activation pathways in the presence of CD28-CD80/CD86 blockade with abatacept.

Objective

To determine whether costimulatory signaling blockade with abatacept prevents psoriasis relapse after ustekinumab withdrawal.

Design, Setting, and Participants

Psoriasis Treatment with Abatacept and Ustekinumab: a Study of Efficacy (PAUSE), a parallel-design, double-blind, placebo-controlled randomized clinical trial, was conducted at 10 sites in the US and Canada. Participant enrollment opened on March 19, 2014, and concluded on April 11, 2016. Participants were adults with moderate to severe plaque psoriasis and received ustekinumab in a lead-in phase. Those who responded to ustekinumab at week 12 were randomized 1:1 to either the continued with ustekinumab group (ustekinumab group) or the switched to abatacept group (abatacept group). Treatment was discontinued at week 39, and participants were followed up for psoriasis relapse until week 88. Statistical analyses were performed in the intention-to-treat (ITT) and safety samples from May 3, 2018, to July 6, 2021.

Interventions

Participants received subcutaneous ustekinumab at weeks 0 and 4 (45 mg per dose for those ≤100 kg; 90 mg per dose for those >100 kg). Participants randomized to the abatacept group at week 12 received subcutaneous abatacept, 125 mg weekly, from weeks 12 to 39 and ustekinumab placebo at weeks 16 and 28. Participants randomized to the ustekinumab group received ustekinumab at weeks 16 and 28 and abatacept placebo weekly from weeks 12 to 39.

Main Outcomes and Measures

The primary end point was the proportion of participants with psoriasis relapse (loss of ≥50% of the initial Psoriasis Area and Severity Index improvement) between weeks 12 and 88. Secondary end points included time to psoriasis relapse, proportion of participants with psoriasis relapse between weeks 12 and 40, and adverse events. The psoriasis transcriptome and serum cytokines were evaluated.

Results

A total of 108 participants (mean [SD] age, 46.1 [12.1] years; 73 [67.6%] men) were treated with open-label ustekinumab; 91 were randomized to blinded treatment. Similar proportions of participants in the abatacept group and the ustekinumab group relapsed between weeks 12 and 88 (41 of 45 [91.1%] vs 40 of 46 [87.0%]; P = .41). Median time to relapse from the last dose of ustekinumab was similar between groups as well: 36 weeks (95% CI, 36-48 weeks) in the abatacept group vs 32 weeks (95% CI, 28-40 weeks) in the ustekinumab group. Similar numbers and rates of adverse events occurred. Abatacept did not maintain suppression of the pathogenic IL-23-mediated psoriasis molecular signature in lesions after ustekinumab withdrawal, and serum IL-19 levels increased.

Conclusions and Relevance

This parallel-design, double-blind randomized clinical trial found that abatacept did not prevent psoriasis relapse that occurred after ustekinumab withdrawal because it did not completely block the pathogenic psoriasis molecular pathways that led to relapse.

Mixed Individual-Aggregate Data on All-Cause Mortality in Bullous Pemphigoid: A Meta-analysis

Importance

The 1-year standardized mortality ratio (SMR) of bullous pemphigoid (BP) has been reported as 2.15 to 7.56 and lower in the US than in Europe.

Objective

To estimate the worldwide 1-year SMR of BP.

Data Sources

PubMed, Embase, Cochrane Library, Google Scholar, Lissa, and gray literature (eg, medRxiv) were screened for studies of BP published from inception to June 10, 2020, with review of reference lists.

Study Selection

Retrospective and prospective studies reporting 1-year all-cause mortality rate in patients with BP and providing age statistics (eg, mean [SD]).

Data Extraction and Synthesis

Two reviewers independently extracted the data. The 1-year SMR was computed in studies reporting 1-year mortality by combining information on age obtained from studies with aggregate data and individual data. Risk of representativity, misclassification, and attrition bias were assessed by a custom tool.

Main Outcomes and Measures

The primary end point was the worldwide 1-year SMR. Secondary analysis included comparison of 1-year SMRs between continents in a meta-regression.

Results

Three studies were performed in the US (n = 260), 1 in South America (n = 45), 16 in Asia (n = 1903), and 36 in Europe (n = 10 132) for a total of 56 unique studies and 12 340 unique patients included in the meta-analysis (mean [SD] age, 77.3 [12.7] years; 55.9% women). The mean (SD) patient age in the United States was 75.6 (13.7) years; in Asia, 73.8 (13.6) years; and in Europe, 78.1 (12.3) years. The worldwide 1-year SMR was estimated at 2.93 (95% CI, 2.59-3.28; I2 = 85.6%) for all 56 studies. The 1-year SMR in the US was 2.40 (95% CI, 0.89-3.90; I2 = 86.3%) for 3 studies; in Asia, 3.53 (95% CI, 2.85-4.20; I2 = 86.3%) for 16 studies; and in Europe, 2.77 (95% CI, 2.35-3.19; I2 = 86.3%) for 36 studies. After adjustment on the expected 1-year mortality rate, the European 1-year SMR did not differ significantly from the 1-year SMR in the United States (-0.48 vs Europe; 95% CI, -2.09 to 1.14; P = .56) and Asia (0.51 vs Europe; 95% CI, -0.56 to 1.58; P = .35). Risk of attrition bias was high (>10% censorship) in 16 studies (28.6%), low in 16 (28.6%), and unclear in 24 (42.9%). Only 4 studies (7.1%) had a sampling method guaranteeing the representativity of BP cases in a population.

Conclusions and Relevance

Although heterogeneity was high and overall quality of follow-up was poor, this meta-analysis confirms the high mortality rate among patients with BP.

Joint AAD-NPF Guidelines of care for the management and treatment of psoriasis with topical therapy and alternative medicine modalities for psoriasis severity measures

Psoriasis is a chronic, inflammatory, multisystem disease that affects up to 3.2% of the United States population. This guideline addresses important clinical questions that arise in psoriasis management and care and provides recommendations based on the available evidence. The treatment of psoriasis with topical agents and with alternative medicine will be reviewed, emphasizing treatment recommendations and the role of dermatologists in monitoring and educating patients regarding benefits as well as risks that may be associated. This guideline will also address the severity assessment methods of psoriasis in adults.

Assessment of the benefit of achieving complete versus almost complete skin clearance in psoriasis: a patient's perspective

Background: Psoriasis is characterized by thick and scaly plaques. The Dermatology Life Quality Index (DLQI) and Physician Global Assessment (PGA) can be used to define its severity.Objective: To assess the impact of complete clearance of skin versus almost clear skin across various disease measures.Methods: Data were collected in a survey of US dermatologists and patients with psoriasis from November 2016-January 2017. Dermatologists completed a 6-point PGA (0 = clear skin, 1 = almost clear skin). Patients completed the DLQI and Work Productivity and Activity Impairment questionnaire (WPAI). Patients with clear and almost clear skin were compared using analysis of covariance for continuous variables, and multivariate logistic regression analysis for categorical variables.Results: Data for 99 and 160 patients with clear and almost clear skin, respectively, were included in the analyses. Patients with clear skin reported less frequent and lower intensity itching, lower total DLQI score (indicating better health-related quality of life), and less impairment of overall work productivity than patients with almost clear skin (all: p < 0.05).Limitations: Limitations relating to general survey methodology.Conclusion: Patients perceived a meaningful difference between clear and almost clear skin. Clear skin is now a realistic treatment target with newer biologics approved in psoriasis.

Disease activity and treatment efficacy using patient-level Psoriasis Area and Severity Index scores from tildrakizumab phase 3 clinical trials

BACKGROUND

It is unclear whether primary efficacy outcomes in plaque psoriasis clinical trials represent residual disease during treatment.

OBJECTIVES

To evaluate supplementing dichotomous efficacy with residual disease activity.

METHODS

This post hoc analysis used pooled, patient-level data after tildrakizumab 100 mg (N = 616) or placebo (N = 309) treatment from reSURFACE 1/2 (NCT01722331/NCT01729754) phase 3 clinical trials of patients with moderate to severe plaque psoriasis.

RESULTS

Median baseline Psoriasis Area and Severity Index (PASI) was 17.9 for patients receiving tildrakizumab 100 mg. At Week 12, median PASI was 2.9, whereas dichotomous PASI 90 response rate was 36.9%, and absolute PASI <5.0, <3.0, and <1.0 were 64.0%, 50.8%, and 23.3%, respectively. At Week 28, median PASI was 1.7, whereas PASI 90 response rate was 51.9%, and absolute PASI <5.0, <3.0, and <1.0 were 75.3%, 62.8%, and 38.0%, respectively. Dermatology Life Quality Index and PASI scores were correlated through Week 28 (r = 0.51, p ≤ .0001).

CONCLUSIONS

Disease activity was more reliably estimated by PASI scores than percentage PASI improvement; this may partially explain efficacy disparities between clinical trials and practice. These results suggest supplementing dichotomous PASI improvement with PASI scores and consideration of patient treatment goals could facilitate clinical decisions.

Joint American Academy of Dermatology-National Psoriasis Foundation guidelines of care for the management of psoriasis with systemic nonbiologic therapies

Psoriasis is a chronic inflammatory disease involving multiple organ systems and affecting approximately 2% of the world's population. In this guideline, we focus the discussion on systemic, nonbiologic medications for the treatment of this disease. We provide detailed discussion of efficacy and safety for the most commonly used medications, including methotrexate, cyclosporine, and acitretin, and provide recommendations to assist prescribers in initiating and managing patients on these treatments. Additionally, we discuss newer therapies, including tofacitinib and apremilast, and briefly touch on a number of other medications, including fumaric acid esters (used outside the United States) and therapies that are no longer widely used for the treatment of psoriasis (ie, hydroxyurea, leflunomide, mycophenolate mofetil, thioguanine, and tacrolimus).

Management of psoriasis as a systemic disease: what is the evidence?

Background

Psoriasis is a chronic, systemic immune‐mediated disease characterized by development of erythematous, indurated, scaly, pruritic and often painful skin plaques. Psoriasis pathogenesis is driven by proinflammatory cytokines and psoriasis is associated with increased risk for comorbidities, including, but not limited to, psoriatic arthritis, cardiovascular disease, diabetes mellitus, obesity, inflammatory bowel disease and nonalcoholic fatty liver disease compared with the general population.

Objectives

To explore the pathophysiological relationship between psoriasis and its common comorbidities and discuss the need for new treatment paradigms that include strategies to reduce systemic inflammation in patients with moderate‐to‐severe psoriasis.

Methods

This narrative review summarizes the published evidence related to the ability of biological therapies to ameliorate the consequences of systemic inflammation in patients with psoriasis.

Results

Current evidence suggests that preventing damage associated with inflammation, and preventing development of future inflammatory damage and comorbidities, may be a potentially achievable treatment goal for many patients with moderate‐to‐severe plaque psoriasis when biological therapies are utilized early in the disease. Encouraging data from recent studies suggest that the loftier goal of reversing existing inflammatory damage and improving signs and symptoms of inflammatory comorbidities could also possibly be attainable.

Conclusions

Results from ongoing prospective studies regarding the effects of biologics on markers of systemic inflammation in patients with psoriasis will strengthen the clinical evidence base that can be used to inform treatment decisions for patients with moderate‐to‐severe psoriasis.

What's already known about this topic?

Psoriasis is a systemic inflammatory disease and treatments are needed to optimize patient outcomes.

What does this study add?

This review discusses new psoriasis treatment paradigms that may potentially reduce effects of systemic inflammation.

Evidence demonstrating that biological treatment may prevent or reverse inflammatory damage associated with psoriasis comorbidities is reviewed.

Perspective From the 5th International Pemphigus and Pemphigoid Foundation Scientific Conference

The 5th Scientific Conference of the International Pemphigus and Pemphigoid Foundation (IPPF), “Pemphigus and Pemphigoid: A New Era of Clinical and Translational Science” was held in Orlando, Florida, on May 15–16, 2018. Scientific sessions covered recent, ongoing, and future clinical trials in pemphigus and bullous pemphigoid, disease activity and quality of life instruments, and the IPPF Natural History Study. Furthermore, the meeting provided an opportunity to hear firsthand from patients, investigators, and industry about their experience enrolling for clinical trials.

Initiating and Monitoring Patients on Biologic Therapy for Psoriasis beyond the FDA: Our more Cautious Approach

Biologics are offering new hope for patients with moderate to severe chronic plaque psoriasis and psoriatic arthritis, and every day more dermatologists are prescribing these medications for their patients. Prior to prescribing a biologic it is important to conduct the proper screening to determine if your patient is an appropriate candidate. While patients are being treated with biologics they need to be monitored carefully to maximize the benefit of the agent and minimize harmful side effects. Apart from the recommendations and requirements of the U.S. Food and Drug Administration (FDA), there are as yet no consensus statements or guidelines addressing the appropriate approach to initiating and monitoring patients being treated with biologics. In this article we will discuss our own approach to initiating and monitoring that we believe is appropriate for patients being treated with biologics. Our recommendations, which in many ways go beyond the recommendations and requirements of the FDA, should not be interpreted as the standard of care.

Ixekizumab treatment for psoriasis: integrated efficacy analysis of three double-blinded, controlled studies (UNCOVER-1, UNCOVER-2, UNCOVER-3)

BACKGROUND

Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin (IL)-17A, is approved for the treatment of moderate-to-severe psoriasis.

OBJECTIVES

This analysis represents an overview of the efficacy outcomes from three phase III psoriasis studies.

METHODS

Data were integrated from the 12-week induction period of three studies in which patients received ixekizumab 80 mg every 2 weeks (IXE Q2W; n = 1169) or every 4 weeks (IXE Q4W; n = 1165) after an initial 160-mg dose for both; etanercept (50 mg biweekly; n = 740; two studies) or placebo (n = 792). The coprimary end points were the percentages of patients with response of static Physician's Global Assessment (sPGA; score 0 or 1) and ≥ 75% improvement in baseline Psoriasis Area and Severity Index (PASI 75) at week 12. Response rates were compared between treatments using the Cochran-Mantel-Haenszel test stratified by study. Treatment comparisons with placebo included data from three studies, whereas etanercept comparisons were based on two studies.

RESULTS

Ixekizumab treatment was superior to placebo (P < 0·001) and etanercept (P < 0·001) on sPGA (0, 1) and PASI 75, with significant differences in PASI improvement at week 1. With IXE Q2W, at week 12, the frequencies of patients achieving PASI 75, 90 and 100 were nearly 90%, 70% and 40%, respectively. Ixekizumab-treated patients showed significantly greater improvement vs. placebo and etanercept in percentage body surface area involvement and fingernail psoriasis. IXE Q2W was superior to IXE Q4W on all treatment outcomes.

CONCLUSIONS

Ixekizumab therapy at both dosing regimens demonstrated rapid onset and superior efficacy to placebo and etanercept, with IXE Q2W providing better outcomes than IXE Q4W during the first 12 weeks of treatment.

Diagnosis and management of pemphigus: Recommendations of an international panel of experts

BACKGROUND

Several European countries recently developed international diagnostic and management guidelines for pemphigus, which have been instrumental in the standardization of pemphigus management.

OBJECTIVE

We now present results from a subsequent Delphi consensus to broaden the generalizability of the recommendations.

METHODS

A preliminary survey, based on the European Dermatology Forum and the European Academy of Dermatology and Venereology guidelines, was sent to a panel of international experts to determine the level of consensus. The results were discussed at the International Bullous Diseases Consensus Group in March 2016 during the annual American Academy of Dermatology conference. Following the meeting, a second survey was sent to more experts to achieve greater international consensus.

RESULTS

The 39 experts participated in the first round of the Delphi survey, and 54 experts from 21 countries completed the second round. The number of statements in the survey was reduced from 175 topics in Delphi I to 24 topics in Delphi II on the basis of Delphi results and meeting discussion.

LIMITATIONS

Each recommendation represents the majority opinion and therefore may not reflect all possible treatment options available.

CONCLUSIONS

We present here the recommendations resulting from this Delphi process. This international consensus includes intravenous CD20 inhibitors as a first-line therapy option for moderate-to-severe pemphigus.

Effect of secukinumab on quality of life and psoriasis-related symptoms: A comparative analysis versus ustekinumab from the CLEAR 52-week study

BACKGROUND

Secukinumab has demonstrated greater sustained skin clearance than ustekinumab through week 52, greater improvement in symptoms and health-related quality of life, and comparable safety profile.

OBJECTIVE

To assess the impact of secukinumab versus that of ustekinumab on complete relief from psoriasis-related symptoms, time to response in terms of health-related quality of life, and cumulative benefit among patients with moderate-to-severe plaque psoriasis.

METHODS

Psoriasis-related pain, itching, and scaling and the Dermatology Life Quality Index (DLQI) score were compared between treatments on the basis of time to complete relief of symptoms and time to DLQI response in the CLEAR trial. Cumulative benefit over 52 weeks based on Psoriasis Area and Severity Index score, symptom relief, and DLQI response were evaluated by area under the curve analysis.

RESULTS

Significantly more patients treated with secukinumab achieved complete relief of pain at weeks 16 and 52 (all P < .05). Complete relief of itching and scaling occurred significantly faster with secukinumab (median, 4 weeks faster for itching and 8 weeks faster for scaling [P < .001]). Response as measured by the DLQI was 4 weeks faster with secukinumab (P < .0001). Cumulative benefits were greater with secukinumab (all P < .05).

LIMITATIONS

Analyses were post hoc.

CONCLUSION

This patient-reported outcome analysis confirms greater and sustained benefits of secukinumab versus those of ustekinumab treatment on patients' lives.

Secukinumab provides better relief from the impact of psoriasis on daily activities and personal relationships than etanercept: results of two phase 3 placebo-controlled randomized clinical trials in moderate-to-severe psoriasis

BACKGROUND

Psoriasis can greatly impact patients' lives, influencing what clothing they wear and impairing their sexual functioning.

OBJECTIVE

To provide a detailed comparison of the impact of secukinumab vs. etanercept on enabling patients with psoriasis to have more normal lives with respect to daily activities (DA) (e.g. choosing clothing) and personal relationships (PR) (e.g. sexual functioning).

METHODS

Baseline to Week 52 ERASURE and FIXTURE data for secukinumab 300 mg and etanercept were analyzed. Treatment differences in mean scores on the DA and PR subscales and items from the Dermatology Life Quality Index were compared. The proportions of subscale and item responders (score = 0) were compared.

RESULTS

Subjects receiving secukinumab (n = 572) achieved greater mean improvement in DA and items (q3 and q4) than subjects receiving etanercept (n = 326; all p < .01 through Week 52). Subjects receiving secukinumab achieved greater mean improvement in PR and items (q8 and q9) than subjects receiving etanercept (subscale: p < .05 at Weeks 8 and 12). Response rates were significantly higher for secukinumab than for etanercept for DA (all p < .0001) and PR (all p < .05 except Weeks 4 and 36).

CONCLUSIONS

Secukinumab 300 mg provides greater improvements and more effective relief from psoriasis impact on DA and PR than etanercept.

Feasibility of carotid artery PET/MRI in psoriasis patients

We report our initial experience of performing integrated PET/MR imaging of the carotid arteries in psoriatic patients. Eleven patients with psoriasis and ten controls underwent carotid PET/MRI. Following injection of the FDG tracer, 3d T1w gradient echo sequence (atMR) was obtained for attenuation correction of PET data. High resolution images of carotid artery were then obtained, including pre-and post-contrast T1-w, T2-w and proton-density images as well as TOF images followed by PET imaging of the torso. From the fused axial PET/MRI, the arterial wall SUVmax and TBRmax was quantified in each slice. MRI images were also evaluated for vessel wall volume, plaque and internal composition. SUVmax and TBRmax were respectively, 1.72 ± 0.38 & 1.17 ± 0.27 in L- CCA, 1.75 ± 0.39 & 1.24 ± 0.19 in R-CCA, 1.59 ± 0.24 & 1.08 ± 0.14 in L-ICA and 1.62 ± 0.27 & 1.15 ± 0.17 in R-ICA in psoriatic patients and 1.74 ± 0.22 & 1.28 ± 0.44 in L- CCA, 1.74 ± 0.33 & 1.07 ± 0.28 in R-CCA, 1.78 ± 0.32 & 1.29 ± 0.39 in L-ICA and 1.60 ± 0.29 & 0.98 ± 0.25 in R-ICA in the controls. No discrete plaques were identified in any of the vessel segments in MRI. PET/MRI is feasible in evaluation of carotid arteries in psoriatic patients.

Two Phase 3 Trials of Adalimumab for Hidradenitis Suppurativa

BACKGROUND

Hidradenitis suppurativa is a painful, chronic inflammatory skin disease with few options for effective treatment. In a phase 2 trial, adalimumab, an antibody against tumor necrosis factor α, showed efficacy against hidradenitis suppurativa.

METHODS

PIONEER I and II were similarly designed, phase 3 multicenter trials of adalimumab for hidradenitis suppurativa, with two double-blind, placebo-controlled periods. In period 1, patients were randomly assigned in a 1:1 ratio to 40 mg of adalimumab weekly or matching placebo for 12 weeks. In period 2, patients were reassigned to adalimumab at a weekly or every-other-week dose or to placebo for 24 weeks. The primary end point was a clinical response, defined as at least a 50% reduction from baseline in the abscess and inflammatory-nodule count, with no increase in abscess or draining-fistula counts, at week 12.

RESULTS

We enrolled 307 patients in PIONEER I and 326 in PIONEER II. Clinical response rates at week 12 were significantly higher for the groups receiving adalimumab weekly than for the placebo groups: 41.8% versus 26.0% in PIONEER I (P=0.003) and 58.9% versus 27.6% in PIONEER II (P<0.001). Patients receiving adalimumab had significantly greater improvement than the placebo groups in rank-ordered secondary outcomes (lesions, pain, and the modified Sartorius score for disease severity) at week 12 in PIONEER II only. Serious adverse events in period 1 (excluding worsening of underlying disease) occurred in 1.3% of patients receiving adalimumab and 1.3% of those receiving placebo in PIONEER I and in 1.8% and 3.7% of patients, respectively, in PIONEER II. In period 2, the rates of serious adverse events were 4.6% or less in all the groups in both studies, with no significant between-group differences.

CONCLUSIONS

Treatment with adalimumab (40 mg weekly), as compared with placebo, resulted in significantly higher clinical response rates in both trials at 12 weeks; rates of serious adverse events were similar in the study groups.

Visualization of atherosclerosis as detected by coronary artery calcium and carotid intima-media thickness reveals significant atherosclerosis in a cross-sectional study of psoriasis patients in a tertiary care center

Background

Psoriasis is a chronic inflammatory disease of the skin and joints that may also have systemic inflammatory effects, including the development of cardiovascular disease (CVD). Multiple epidemiologic studies have demonstrated increased rates of CVD in psoriasis patients, although a causal link has not been established. A growing body of evidence suggests that sub-clinical systemic inflammation may develop in psoriasis patients, even from a young age. We aimed to evaluate the prevalence of atherosclerosis and identify specific clinical risk factors associated with early vascular inflammation.

Methods

We conducted a cross-sectional study of a tertiary care cohort of psoriasis patients using coronary artery calcium (CAC) score and carotid intima-media thickness (CIMT) to detect atherosclerosis, along with high sensitivity C-reactive protein (hsCRP) to measure inflammation. Psoriasis patients and controls were recruited from our tertiary care dermatology clinic. Presence of atherosclerosis was defined using validated numeric values within CAC and CIMT imaging. Descriptive data comparing groups was analyzed using Welch’s t test and Pearson Chi square tests. Logistic regression was used to analyze clinical factors associated with atherosclerosis, and linear regression to evaluate the relationship between psoriasis and hsCRP.

Results

296 patients were enrolled, with 283 (207 psoriatic and 76 controls) having all data for the hsCRP and atherosclerosis analysis. Atherosclerosis was found in 67.6 % of psoriasis subjects versus 52.6 % of controls; Psoriasis patients were found to have a 2.67-fold higher odds of having atherosclerosis compared to controls [95 % CI (1.2, 5.92); p = 0.016], after adjusting for age, gender, race, BMI, smoking, HDL and hsCRP. In addition, a non-significant trend was found between HsCRP and psoriasis severity, as measured by PASI, PGA, or BSA, again after adjusting for confounders.

Conclusions

A tertiary care cohort of psoriasis patients have a high prevalence of early atherosclerosis, increased hsCRP, and psoriasis remains a risk factor for the presence of atherosclerosis even after adjustment of key confounding clinical factors. Psoriasis may contribute to an accelerated systemic inflammatory cascade resulting in increased risk of CVD and CV events.

Impact of psoriasis flare and remission on quality of life and work productivity: a real-world study in the USA

Although psoriasis patients often report a negative impact on health-related quality of life (HRQoL) and work productivity, less is known about how disease burden varies between periods of flare and remission. The aim of this study was tocompare HRQoL and work productivity by disease activity level. Data were extracted from Adelphi 2011/2013 Disease Specific Programmes, two real world surveys of US dermatologists and psoriasis patients. HRQoL was measured using the EuroQOL 5-Dimension Health Questionnaire (EQ-5D) and Dermatology Life Quality Index (DLQI). Work productivity was measured using the Work Productivity Activity index (WPAI). Three levels of disease activity were constructed based on physician reports: remission, active not flaring, active, and flaring. Multivariable regression analyses explored the relationship between disease activity, HRQoL and work productivity, controlling for differences in demographics and comorbidities. Out of 681 psoriasis patients 24% were in remission, 62% had active disease without flaring, and 15% experienced active disease and were currently flaring. Greater disease activity was associated with worse HRQoL. EQ-5D scores decreased with more active disease (remission vs. active not flaring vs. active and flaring: 0.93 vs. 0.90 vs. 0.82; p&lt;0.05), while DLQI scores increased (remission vs. active not flaring vs. active and flaring: 2.0 vs. 5.00 vs. 8.7; p&lt;0.05). WPAI scores increased with disease activity indicating increased productivity loss (remission vs. active not flaring vs. active and flaring: 5.9 vs. 14.8 vs. 26.9; p&lt;0.05). The same trends were confirmed by multivariable regression analyses.

Satisfaction with current psoriasis treatment: misalignment between physician and patient perceptions

Psoriasis patients often report dissatisfaction with treatment. However, the extent to which patients and their treating dermatologists are aligned regarding satisfaction with psoriasis therapy is largely unknown. This was explored using data derived from the Adelphi 2011/2013 Psoriasis Disease Specific Programmes, two real world surveys of US dermatologists and their patients. Physicians and patients independently reported their satisfaction with psoriasis control (satisfied, dissatisfied). Two levels of satisfaction alignment between physician and patient responses were constructed: aligned (same responses) and misaligned (different responses). In addition, dermatologists provided patient treatment history and disease/symptom severity whereas patients reported data on health-related quality of life (HRQoL), using the EuroQOL 5-Dimension Health Questionnaire (EQ-5D) and Dermatology Life Quality Index (DLQI), and work productivity using the Work Productivity Activity index (WPAI). Multivariate regressions were employed to examine the relationship between satisfaction alignment, overall disease and symptom severity, HRQoL, and work productivity controlling for differences in patient demographics and comorbidities.From 627 paired dermatologist and psoriasis patient records, 512 (81.7%) and 115 (18.3%) cases fell into the 'aligned' and 'misaligned' groups, respectively. Compared with patients in the aligned group, those in the misaligned group had more moderate to severe psoriasis (82.3% vs. 43.7%), moderate to severe itching (45.6% vs. 27.8%), pain (23.0% vs. 10.6%), and scaling (54.8% vs. 36.1%), and had lower current biologics use (27.0% vs. 42%) (all p&lt;0.05). The misaligned group was associated with reduced HRQoL (lower EQ-5D score: 0.86 vs. 0.91; higher DLQI score: 7.06 vs. 4.23) and greater work productivity loss (higher WPAI scores: 18.27 vs. 11.43) (all p&lt;0.05). Multivariate analyses confirmed these results (p&lt;0.05). Almost 1 in 5 patients were misaligned with their dermatologist's level of satisfaction with their psoriasis treatment; misalignment was associated with increased disease and symptom severity, reduced HRQoL, and reduced work productivity.

Evaluation of ELISA testing for BP180 and BP230 as a diagnostic modality for bullous pemphigoid: a clinical experience

Bullous pemphigoid (BP) is a common autoimmune blistering disorder of the elderly. Several diagnostic modalities are available, including clinical impression, histopathology, direct and indirect immunofluorescence, and enzyme-linked immunosorbent assay (ELISA) detection of pathogenic antibodies. In this study, we aim to examine the utility of the newest test, ELISA, in comparison to the constellation of other tests. We describe our clinical experience in which 170 patients diagnosed with bullous pemphigoid had multiple tests performed. BP180 alone showed a sensitivity of 54 % and specificity of 94 %. The positive predictive value (PPV) is 95 % while the negative predictive value (NPV) is 52 %. BP230 alone yielded a sensitivity of 48 % and specificity of 94 %. The PPV is 94 % and the NPV is 49 %. Using both tests in combination yielded a sensitivity of 66 % and specificity of 89 %. The PPV of at least one of two tests returning positive is 92 % while the NPV of dual negative tests is 58 %. Use of ELISAs for suspected cases of BP are an inadequate standalone test, and are only helpful in making the diagnosis should they return positive. However, they would appear to miss about one-third of cases.

Relationship between psoriasis severity, clinical symptoms, quality of life and work productivity among patients in the USA

BACKGROUND

Psoriasis is a chronic disease, and many patients experience itching, painful skin and scaling. The relationship between psoriasis severity and symptom severity, quality of life (QoL) and work productivity is not fully understood.

AIM

To examine how QoL, work productivity and clinical symptoms vary between patients with mild, moderate and severe psoriasis.

METHODS

During a recent US survey, dermatologists provided information on overall disease severity, symptom severity and comorbidities. Patients with psoriasis completed QoL and work productivity instruments: the EuroQoL 5-Dimension Health (EQ-5D) questionnaire, the Dermatology Life Quality Index (DLQI), and the Work Productivity and Activity Impairment (WPAI) questionnaire. Multivariate regression was used to explore the relationship between these outcome variables and psoriasis severity, controlling for differences in demographics and comorbidities.

RESULTS

The study analysed 694 patients (55% male; mean age: 44 years); 48%, 46% and 6% had mild, moderate and severe psoriasis, respectively. Scaling was the most common symptom, which was experienced by 82% of patients, followed by itching (73%) and pain (32%). Increased psoriasis severity was associated with increased itching, pain and scaling, and with reduced QoL (decrease in EQ-5D scores: moderate vs. mild -0.04, severe vs. mild -0.18; increase in DLQI: moderate vs. mild 2.97, severe vs. mild 7.95). WPAI scores increased with severity, indicating greater impairment (moderate vs. mild: 11.77, severe vs. mild 18.73).

CONCLUSIONS

Patients with more severe psoriasis experienced more severe symptoms and had a greater reduction in QoL and work productivity. It is important that physicians recognize the impact of severe disease on patients' lives and take steps to address this.

Patient satisfaction with current psoriasis treatment: a real-world study in the USA

Psoriasis patients often report dissatisfaction with treatment. However, it is less clear how the severity of key psoriasis symptoms (painful skin, itching, and scaling) as well as overall disease severity influence patient dissatisfaction levels. Using the Adelphi 2011/2013 Psoriasis Disease Specific Programmes, two "real world" surveys of US dermatologists and their patients, patient satisfaction was evaluated. Dermatologists provided data on disease characteristics, while patients indicated their satisfaction with existing treatment. Physician-reported severity (none, mild, moderate/severe) of psoriasis-related itching, pain, and scaling, overall disease severity (mild, moderate and severe) and therapy type were compared by patient satisfaction levels (satisfied vs. dissatisfied). Multivariate regressions examined the relationship between patient satisfaction, clinical symptoms, and psoriasis overall disease severity, controlling for differences in patient demographics and comorbidities. The sample comprised 633 psoriasis patients (56% male) with a mean age of 45. Overall, 18% of patients reported dissatisfaction with their psoriasis treatment. Dissatisfied patients were more likely to have moderate (65% vs. 40%) or severe (21% vs 3%) psoriasis compared to patients who were satisfied (both p<0.05). Dissatisfied patients were also more likely to have more severe pain (30% moderate-to-severe pain vs. 9%), more severe itching (61% moderate-to-severe itching vs. 25%), and more severe scaling (68% moderate-to-severe scaling vs. 33%) than satisfied patients (all p< 0.05). Multivariate analyses confirmed these results. Clinicians should be aware that some psoriasis patients, especially those with severe overall disease or symptoms, may be dissatisfied and are in need of better treatment.

Increased severity of itching, pain, and scaling in psoriasis patients is associated with increased disease severity, reduced quality of life, and reduced work productivity

BACKGROUND

Psoriasis patients report that this disease can impact on their health-related quality of life (HR-QoL) and work productivity. It is important to understand how this is influenced by the clinical characteristics of psoriasis such as symptom severity. Common symptoms include itching, pain, and scaling but the psychosocial impact these features have on patients is not well understood.

OBJECTIVE

To explore the impact of psoriasis symptoms (itching, pain, and scaling) on HR-QoL and work productivity.

METHOD

Data were extracted from the Adelphi 2011 and 2013 Psoriasis Disease Specific Programmes - two real world surveys of US dermatologists and their psoriasis patients.  HR-QoL was measured using the Dermatology Life Quality Index (DLQI) and EuroQOL 5-Dimension Health Questionnaire (EQ-5D). Work productivity loss was measured by the Work Productivity and Activity Impairment (WPAI) questionnaire. The impact of symptom severity (none, mild, moderate/severe) for itching, pain, and scaling on DLQI, EQ-5D, and WPAI scores were examined, controlling for differences in demographics and co-morbidities.

RESULTS

Patient mean age was 44 years and 55% were male. Moderate/severe itching, pain, and scaling were experienced by 33%, 13%, and 41% of patients, respectively. Controlling for differences in demographics and co-morbidities, increased symptom severity was associated with reduced HR-QoL. Accordingly, EQ-5D scores decreased with itching severity (moderate/severe vs. none: -0.07; 95% confidence interval [CI] =-0.09, -0.04), whereas DLQI scores increased (moderate/severe versus none: 4.9; CI = 3.9, 5.9) (both p&lt;0.05). WPAI scores increased with itching severity, indicating increased work productivity loss (moderate/severe versus none: 17.6, CI = 11.8, 23.5, p&lt;0.05). The same pattern was observed for pain and scaling.

CONCLUSIONS

Among the patients studied, increased severity of psoriasis-related itching, pain, and scaling was associated with reduced health-related QoL and work productivity.

Psoriasis disease severity affects patient satisfaction with treatment

BACKGROUND

Patients with psoriasis are often dissatisfied with available treatments, but contributing factors are not well defined.

OBJECTIVE

Examine relationships between psoriasis severity, patient characteristics, and treatment satisfaction.

METHODS

Patients with psoriasis were classified into mild and moderate-to-severe groups based on self-reported data. Demographics, comorbidities, symptoms, and multiple treatment satisfaction outcomes were compared between groups. Predictors of patient satisfaction with treatment were examined using linear regression models.

RESULTS

The analyses included 773 patients (407 mild; 366 moderate-to-severe). The percentage of patients reporting satisfaction with treatment was low overall, ranging from 8.6% to 61.7% for the mild and 13.9% to 49.5% for the moderate-to-severe group. Satisfaction among biologics users was also low (≤53%; 50% of satisfaction rates &lt;40%). Regression results consistently showed greater dissatisfaction with current treatment among moderately to severely affected patients.

CONCLUSION

Many psoriasis patients were dissatisfied with their treatment; moderate-to-severe patients expressed significantly less satisfaction than mild patients.

Clinical symptoms and self-reported disease severity among patients with psoriasis - Implications for psoriasis management

BACKGROUND

Pain, itching, burning and irritation are common symptoms of psoriasis but have not been well characterized by overall psoriasis severity.

METHODS

Using 2012 syndicated psoriasis patient survey data, 1050 subjects were classified into mild (n = 610) and moderate-to-severe (n = 440) psoriasis severity groups based on self-reporting. Demographics, comorbid medical conditions and patient-reported key symptoms (i.e. flare-up frequency, psoriasis-related pain, itching, burning, hurting, irritation) were compared between groups. Multiple regressions were employed to examine the impact of overall psoriasis severity on each key symptom, controlling for demographics and comorbidities.

RESULTS

Mild patients were older; more than 20% in both groups had joint pain and depression. Over 35 and 68% of the moderate-to-severe patients reported severe pain between or during flare-ups, respectively, and over 79% reported frequent bothersome itching. Controlling for between-group differences, moderate-to-severe patients had worse pain, were more likely to have continual flare-ups (odds ratio = 3.0) and flare-ups more than once monthly (odds ratio = 3.0), and reported more bothersome symptoms than patients with mild disease (all p < 0.05).

CONCLUSION

The presence and level of particular symptoms increase with self-reported disease severity in patients with psoriasis. Careful investigation of symptoms in tandem with clinical observation is important for effective psoriasis management.
