RESUMEN
BACKGROUND: Psoriasis is an inflammatory skin disease that impacts a heterogeneous group of patients and can have multiple clinical manifestations. Risankizumab is approved for the treatment of moderate-to-severe plaque psoriasis. OBJECTIVES: To evaluate the long-term efficacy of risankizumab according to baseline patient characteristics, and for the treatment of high-impact disease manifestations (nail, scalp and palmoplantar psoriasis), through 256 weeks of continuous treatment in the phase 3 LIMMitless study. METHODS: This subgroup analysis evaluated pooled data from patients with moderate-to-severe plaque psoriasis who were randomized to risankizumab 150 mg during two double-blind, phase 3, 52-week base studies (UltIMMa-1/2; NCT02684370/NCT02684357) and were enrolled in the phase 3 LIMMitless open-label extension study (NCT03047395). Subgroup assessments included the proportion of patients who achieved ≥90%/100% improvement in Psoriasis Area and Severity Index (PASI 90/100). Among patients with nail, scalp and/or palmoplantar psoriasis in addition to skin psoriasis, assessments included changes from baseline in and resolution of these three psoriatic manifestations. RESULTS: Overall, a numerically similar proportion of patients (N = 525) achieved PASI 90/100 through Week 256, regardless of their baseline age, sex, body mass index, weight, PASI or psoriatic arthritis status. Patients with nail, scalp and/or palmoplantar psoriasis experienced substantial improvements in manifestation-specific indices (mean improvement from baseline to Week 256 of >81%, >94% and >97%, respectively); in patients with all three manifestations (N = 121), 44.6% achieved complete clearance of these manifestations at Week 256. CONCLUSIONS: Risankizumab demonstrated generally consistent efficacy through 256 weeks across patient subgroups and showed durable long-term efficacy for psoriatic disease manifestations.

This Summary of Research overviews the results of the VOLTAIRE-X study (NCT03210259), which looked at what happened when people with plaque psoriasis continually took the adalimumab reference product (adalimumab RP; known by the brand name Humira®) or switched three times between taking the adalimumab RP and BI 695501 (adalimumab-adbm, known by the brand name Cyltezo®), an adalimumab biosimilar. The VOLTAIRE-X study showed that the pharmacokinetics of adalimumab were similar in people who stayed continuously on adalimumab RP and people who switched between adalimumab RP and adalimumab-adbm. There were no differences in effectiveness, side effects, or antibodies to adalimumab when comparing people who stayed continuously on adalimumab RP with those who switched between adalimumab RP and the adalimumab biosimilar adalimumab-adbm. On the basis of these results, adalimumab-adbm was approved by the US Food and Drug Administration (FDA) as interchangeable with adalimumab RP, meaning that a pharmacist can substitute the biosimilar adalimumab-adbm for adalimumab RP without requiring permission from the original prescriber (unless required to by state law).

Importance: Other than single-center case studies, little is known about generalized pustular psoriasis (GPP) flares. Objective: To assess GPP flares and their treatment, as well as differences between patients with and patients without flares documented in US electronic health records (EHRs). Design, Setting, and Participants: This retrospective cohort study included adult patients with GPP (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision code L40.1) identified in Optum deidentified EHR data between July 1, 2015, and June 30, 2020. The index GPP diagnosis was the first occurrence in the EHR, with no coded history of GPP for at least 6 months prior. Flare episodes were identified using an algorithm based on diagnosis coding, care setting, type of clinician, GPP disease terms, and flare terms and attributes in the EHR. Main Outcomes and Measures: Flare episodes were characterized by the frequency of occurrence per patient, the care setting in which they were identified, the type of specialist managing the episode, associated symptoms, and the type of treatment before, during, and after the episode. Patients were divided into groups based on whether or not they had a flare episode documented in their EHR. Comparisons were made between the groups based on demographic characteristics, comorbidity burden, health care use, and treatments. Results: Of 1535 patients with GPP (1018 women [66.3%]; mean [SD] age, 53.4 [14.7] years), 271 had 513 flares documented. Compared with patients without flares, patients with flares had a 34% higher mean (SD) Charlson Comorbidity Index score (2.80 [3.11] vs 2.09 [2.52]), were almost 3 times more likely to have inpatient visits (119 of 271 [44%] vs 194 of 1264 [15%]), were more than twice as likely to have emergency department (ED) visits (126 of 271 [47%] vs 299 of 1264 [24%]), and had higher use of almost all treatment classes. Flares were identified in outpatient (271 of 513 [53%]), inpatient (186 of 513 [36%]), and ED (48 of 513 [9%]) settings. The most common treatments during flares were topical corticosteroids (35% of episodes [178 of 513]), opioids (21% [106 of 513]), other oral treatments, (eg, methotrexate, cyclosporine, tacrolimus; 13% [67 of 513]), and oral corticosteroids (11% [54 of 513]). Almost one-fourth of flare episodes (24% [122 of 513]) had no dermatologic treatment 30 days before, during, or 30 days after a flare episode. Conclusions and Relevance: This cohort study suggests that there is significant unmet need for the treatment of GPP and its flares, as evidenced by patients seeking treatment in inpatient and ED settings, as well as the lack of advanced treatments.

BACKGROUND: BI 695501 is an FDA-approved biosimilar to adalimumab reference product (RP). VOLTAIRE-X was a randomized clinical trial to assess outcomes with a biosimilar monoclonal antibody in line with the FDA requirements for designation as an 'interchangeable' biosimilar. OBJECTIVE: The aim of this study was to assess whether multiple switches between adalimumab RP and BI 695501 lead to equivalent pharmacokinetics and a similar safety and immunogenicity profile compared with continuous adalimumab RP. METHODS: We conducted a phase III, double-blind, randomized controlled trial between July 19, 2017, and April 16, 2019. There were 49 investigational sites across Europe and North America. Of 323 screened patients with moderate-to-severe chronic plaque psoriasis, 259 were treated with adalimumab RP during the run-in period. Of these, 118 and 120 were randomized to the continuous or switching arms, respectively. Interventions consisted of a run-in period with adalimumab RP 80 mg subcutaneously (SC) on Day 1, then 40 mg SC every other week (EOW) Weeks 2-12. Patients were then randomized to receive adalimumab RP 40 mg EOW Weeks 14-48 (continuous arm) or BI 695501 40 mg Weeks 14 and 16, adalimumab RP 40 mg Weeks 18 and 20, and BI 695501 40 mg EOW Weeks 22 to 48 (switching arm); all interventions were given SC. Primary endpoints were pharmacokinetics parameters, area under the plasma concentration-time curve (AUCτ,30-32) and maximum observed drug plasma concentration (Cmax,30-32), measured after the third switch during the Week 30-32 dosing interval. RESULTS: 238 patients (mean [standard deviation] age 44.9 [13.8]; 66.0% male) were treated in the switching (n = 118) or continuous arms (n = 120). Adjusted mean Cmax,30-32 was 7.08 and 7.00 µg/mL in the switching and continuous treatment arms, respectively; adjusted mean AUCτ,30-32 was 2025.8 and 1925.9 µg h/mL. Point estimate for mean ratio for AUCτ,30-32 was 105.2% (90.2% confidence interval [CI] 96.6-114.6), and 101.1% (90.2% CI 93.3-109.7) for Cmax,30-32. Both CIs were within a predefined bioequivalence range of 80.0-125.0%. Treatment-emergent adverse events led to discontinuation in 0.8% and 1.7% of patients in the switching and continuous treatment arms, and Psoriasis Area and Severity Index (PASI) scores were highly similar in the two arms across the entire trial period. CONCLUSIONS: Pharmacokinetic equivalence was demonstrated, with highly similar efficacy and immunogenicity, and comparable safety observed in patients with chronic plaque psoriasis who received either adalimumab RP continuously or who switched between adalimumab RP and BI 695501.

Psoriatic involvement in areas of the body such as nails, palms and soles (palmoplantar), and scalp is associated with dramatically negative effects on quality of life relative to involvement elsewhere in the body. Although numerous evidence-based studies demonstrate the efficacy of biologics for overall skin clearance in moderate-to-severe plaque psoriasis (including tumor necrosis factor α [TNFα] inhibitors and interleukin [IL]-17A, IL-12/IL-23, IL-23, IL-17F, and IL-17A/F inhibitors), large, randomized, placebo-controlled clinical studies of psoriasis with nail, palmoplantar, and scalp involvement are needed to better inform decision-making in clinical practice. Moreover, biologic failure caused by drug ineffectiveness is a common occurrence in patients who do not respond, lose response, or are intolerant to treatment. Brodalumab is a fully human IL-17 receptor A antagonist that demonstrates high rates of skin clearance among the latest generation of biologic therapies for treatment of moderate-to-severe psoriasis. This review summarizes current literature on the efficacy of brodalumab and other therapies in difficult-to-treat psoriasis including psoriasis in difficult-to-treat locations (such as psoriasis with nail, palmoplantar, or scalp involvement) and psoriasis in patients whose disease did not respond to other biologics.
RESUMEN
INTRODUCTION: We sought to understand key symptoms of generalized pustular psoriasis (GPP) and to confirm the relevance to patients and content validity of the Psoriasis Symptom Scale (PSS) in GPP. METHODS: A targeted literature review and clinical expert interviews were conducted as background research. Patients were interviewed individually (involving concept elicitation and cognitive interviews), and a separate patient workshop was conducted to determine disease-specific symptoms of importance. RESULTS: Seven participants with moderate (n = 4), severe (n = 2), and mild (n = 1) GPP and clinician diagnosis were interviewed. During concept elicitation, all participants indicated that pustules may underlie other symptoms. Symptoms reported by all patients were pain, redness, itch, burning, and discomfort. The PSS symptoms of pain, itching, burning, and redness were reported by ≥ 86% of patients as most frequently experienced. Upon debriefing, the PSS was well understood. Relevance and importance of these symptoms was confirmed in the GPP patient workshop. CONCLUSION: Participant feedback found the PSS measure to be relevant and easy to understand. The symptoms included in the instrument, pain, redness, itch, and burning, were most frequently reported, important, and well understood by patients. Study results provided support for the content validity of the PSS for use as endpoints in GPP clinical trials.
Generalized pustular psoriasis (GPP) is a severe rare disease, including redness and boils that sometimes come with fever and other general symptoms. This study asked patients with GPP about their key symptoms, and whether the Psoriasis Symptom Scale (PSS) is relevant to them as patients. The PSS is a questionnaire with the symptoms pain, itching, burning, and redness. We searched the literature and interviewed clinical experts to guide the patient interviews. Patients were recruited through clinical sites and the National Psoriasis Foundation (NPF). The interviews discussed GPP symptoms and the PSS questionnaire. Patients with GPP were also asked about commonly experienced symptoms in a workshop. Most patients had moderate to severe GPP. Patients in both the interviews and workshop described experiencing pain, redness, itch, burning, and discomfort with their boils. During interviews, the patients said the PSS questionnaire was easy to understand. Patients in the workshop also found the PSS to be relevant and easy to understand. Patients agreed the symptoms in the PSS, pain, redness, itch, and burning, were common and important. Study results support the PSS for use with patients in clinical trials.
RESUMEN
Invasive fungal infection is a rare but serious potential consequence of biologic therapy. Herein, we report a case of cryptococcal meningitis in an otherwise immunocompetent patient receiving ixekizumab for the treatment of severe plaque psoriasis. We also discuss the relevant immunologic role of interleukin-17, the potential for synergistic effects when transitioning biologic therapies, and clinical considerations when treating patients with such medications. To the best of our knowledge, this is the first case of cryptococcal meningitis reported in a patient treated with ixekizumab.

BACKGROUND: Despite the emergence of multiple biologic drug options for psoriasis, unmet treatment needs remain. Biologic therapies can vary in their effectiveness and adverse events, and many patients experience a loss of treatment effect over time. After lack of response, treatment may be switched to a biologic with a different mechanism of action. Brodalumab, a human interleukin-17 (IL-17) receptor A antagonist, is approved for the treatment of adult patients with moderate-to-severe psoriasis with inadequate response or loss of response to prior systemic therapies. Because brodalumab targets the IL-17 receptor instead of the ligand itself, it not only targets a broader set of IL-17 isoforms but also may be effective in patients who received prior IL-17 inhibitors or failed to respond to anti–IL-17 treatment. This is supported by long-term evidence from clinical trials and real-world studies of patients receiving brodalumab who were previously treated with IL-17 inhibitors. Additionally, brodalumab produces reliable treatment effects after use of biologics with other mechanisms of action, such as tumor necrosis factor α and IL-12/IL-23 inhibitors, as well as after the use of multiple biologic therapies. For patients with psoriasis with inadequate response to one or more biologic therapies, brodalumab is an option that has the ability to lead to long-term skin clearance.

Pustular psoriasis is an unusual form of psoriasis that frequently presents clinical challenges for dermatologists. The condition presents with pustules on an erythematous background and has two distinct subtypes: localized disease on the palms and soles, called palmoplantar pustulosis (PPP), and generalized pustular psoriasis (GPP). The involvement of the fingers, toes, and nails is defined as a separate localized variant, acrodermatitis continua of Hallopeau, and is now thought to be a subset of PPP. The rarity of pustular psoriasis frequently makes the correct diagnosis problematic. In addition, treatment is limited by a relative lack of evidence-based therapeutic options. Current management is often based on existing therapies for standard plaque psoriasis. However, there remains a need for treatments with high, sustained efficacy and a rapid onset of action in pustular psoriasis. Recent advances in understanding of the pathogenesis of pustular psoriasis have provided insights into potential therapies. Treatment of pustular psoriasis is generally determined by the extent and severity of disease, and recent years have seen an increasing use of newer agents, including biologic therapies. Current classes of biologic therapies with US Food and Drug Administration and European Medicines Agency approval for treatment of moderate-to-severe plaque psoriasis in the USA (and elsewhere) include tumor necrosis factor alpha inhibitors (adalimumab, certolizumab pegol, etanercept, infliximab), interleukin (IL)-17 inhibitors (brodalumab, ixekizumab, secukinumab), an IL-12/23 inhibitor (ustekinumab), and IL-23 inhibitors (guselkumab, risankizumab, tildrakizumab). Recently, specific inhibitors of the IL-36 pathway have been evaluated in GPP and PPP, including spesolimab, an IL-36 receptor inhibitor which has shown promising results in GPP. The emerging drugs for pustular psoriasis offer the possibility of rapid and effective treatment with lower toxicities than existing therapies. Further research into agents acting on the IL-36 pathway and other targeted therapies has the potential to transform the future treatment of patients with pustular psoriasis. This article reviews the clinical features of PPP and GPP, and current understanding of the genetics and immunopathology of these conditions; it also provides an update on emerging treatments.
Pustular psoriasis is a skin condition where people develop small pus-filled blisters on their skin. Pustular psoriasis may affect certain areas of the body, such as the palms and/or the soles. This is called palmoplantar pustulosis (PPP for short). Another type of pustular psoriasis can affect most of the body called generalized pustular psoriasis (GPP for short). Not many people have PPP or GPP. Around 512 in every 10,000 people worldwide develop PPP. GPP is even rarer, affecting only 27 out of every 1 million people. In addition to being relatively uncommon, these conditions are challenging to treat. This article aims to help doctors who treat skin conditions (dermatologists) to identify and treat people with pustular psoriasis. Currently there is no standard treatment for GPP and PPP in the USA or Europe, but several medicines are approved for treatment of GPP in Japan. Doctors often use treatments that have been shown to work in plaque psoriasis, which is the most common type of psoriasis, to treat people with GPP and PPP. Traditional treatments for PPP and GPP are often not effective. Researchers are working on developing new effective treatments for pustular psoriasis that may work more rapidly and have fewer side effects. These are expected to be available in the next few years.
RESUMEN
INTRODUCTION: In the USA, psoriasis affects approximately 3% of the population and costs more than $110 billion annually. The development of targeted biologics has revolutionized psoriasis management, but at an increasing cost. According to Joint AAD/NPF guidelines, an important need exists to identify biomarkers that can predict the appropriate biologic agent for patients. METHODS: A survey of community dermatologists was developed to address (1) significant factors influencing biologic therapy utilization in psoriasis; (2) the clinical utility of a test stratifying biologic response. RESULTS: Respondents confirmed that trial and error leads to frequent biologic switching. The survey indicated that 82% of dermatologists switch 10-30% of their patients in the first year and 98% switch intra-class for at least 50% of non-responding patients. The trial and error is due, in part, to formularies influencing the physician 77% of the time, with only 14% reporting that their first choice and the formulary alignment is greater than 75%. Compounding trial and error, 93% of the physicians report that they wait at least 12 weeks before determining non-response, in alignment with AAD/NPF guidelines. The lack of precision medicine and this trial-and-error approach result in unnecessary wasted spending and suboptimal patient outcomes. After being given an overview of Mind.Px, a dermal biomarker patch used to predict therapeutic response to a biologic class, survey participants expressed that: 93% would utilize Mind.Px results to determine first-line therapy even if this differed from initial clinical choice 100% would utilize Mind.Px if part of the prior authorization process 98% say Mind.Px would improve patient outcomes 81% reported Mind.Px would help with prior authorization process CONCLUSIONS: Surveyed dermatologists believe a test that predicts psoriasis treatment response to a class of biologic drugs would lessen trial and error, provide a tool for physicians to make more informed decisions about drug selection, improve patient outcomes, and significantly reduce wasted spending.
RESUMEN
Penile calciphylaxis is a rare cause of penile gangrene and is typically associated with multiple comorbidities, most commonly diabetes mellitus and hyperparathyroidism. It demonstrates a high mortality rate of 64% and is seen almost exclusively in patients with end-stage renal disease on hemodialysis. Underreporting of this disease likely occurs, contributing to a paucity of data and lack of formal therapeutic guidelines and approved treatments. Conflicting guidance exists regarding effective treatment strategies, with most formal literature existing in the form of case reports. Herein, we describe a 44-year-old man with end-stage renal disease on hemodialysis who presented with a 2-month history of nonhealing wounds on his penis and lower extremities.
RESUMEN
Psoriasis is an immune-mediated inflammatory skin disease associated with numerous inflammatory comorbidities, including increased cardiovascular risk. The interleukin (IL)-23/IL-17 axis plays a central role in the immunopathogenesis of psoriasis and related comorbidities by acting to stimulate keratinocyte hyperproliferation and feed-forwarding circuits of perpetual T cell-mediated inflammation. IL-17 plays an important role in the downstream portion of the psoriatic inflammatory cascade. This review discusses the distinct mechanisms of action of IL-17 and IL-23 in the immunopathogenesis of psoriasis and related comorbidities plus the significant therapeutic benefits of selectively inhibiting these cytokines in patients with moderate to severe plaque psoriasis.
RESUMEN
Ixekizumab is a humanized monoclonal antibody that exhibits its immunomodulatory effects by binding to interleukin 17A (IL-17A), a proinflammatory cytokine. It was approved for the treatment of plaque psoriasis by the Food and Drug Administration in 2016. Ixekizumab has demonstrated superiority in clinical trials against etanercept, with no significant difference in the side effect profile. The chronicity of psoriasis requires continual treatment to achieve disease clearance. Many factors may affect adherence to treatment including patient satisfaction, patient preferences, medication cost, and medication side effects. Limited data on patient adherence, satisfaction, and preference exists in formal literature. Often, surrogate measures must be used to extrapolate information regarding these measures. In this narrative review, we describe patient adherence, satisfaction, and preferences via both direct and surrogate measures as they relate to ixekizumab treatment for moderate-to-severe plaque psoriasis.

Background: BI 695501 is an approved biosimilar to Humira® reference product (RP). Research design and methods: In this randomized Phase III trial (VOLTAIRE-PSO), patients with moderate-to-severe chronic plaque psoriasis received BI 695501 or adalimumab RP (24-week treatment). Primary efficacy endpoint: the proportion of patients with ≥75% reduction in Psoriasis Area and Severity Index (PASI 75) response at week 16 (±18% equivalence limits for two-sided 95% confidence interval between treatment groups). Safety, pharmacokinetics, and immunogenicity were also assessed. Results: Baseline characteristics were balanced between treated groups (BI 695501, n = 159; adalimumab RP, n = 158). PASI 75 response rates (full analysis set, n = 158; n = 157) were 68.2% (BI 695501) and 70.4% (adalimumab RP) at week 16 (95% CI: -14.4%, 8.7%), and 75.3% and 72.4%, at week 24, respectively. At week 24, 41.5% (BI 695501) and 44.9% (adalimumab RP) of treated patients had treatment-emergent adverse events (AEs), 3.1% and 4.4% had serious AEs, and 0.0% and 1.9% had AEs of special interest. Of treated patients, 75.3% (BI 695501) and 77.9% (adalimumab RP) were anti-drug antibody-positive. Conclusion: These data demonstrate equivalent efficacy and highly similar safety and immunogenicity between BI 695501 and adalimumab RP in patients with chronic plaque psoriasis. Study identifier: NCT02850965.
