RESUMEN
BACKGROUND: Real-world studies assessing the comparative effectiveness of biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) as first-line targeted therapy are scarce. We analyzed the real-world persistence and effectiveness of etanercept (ETN), adalimumab (ADA), and Janus kinase inhibitors (JAKis) as first-line therapy in b/tsDMARD-naïve patients with rheumatoid arthritis (RA). METHODS: Adults (≥ 18 years) enrolled in the CorEvitas RA Registry and initiating ETN, ADA, or a JAKi (alone or in combination with csDMARDs) between November 2012 and June 2021 were included if they had 6 and/or 12 months' follow-up. Treatment persistence and effectiveness outcomes including the change in Clinical Disease Activity Index (CDAI) and patient-reported outcomes (PROs) were evaluated at follow-up, adjusting for covariates using linear and logistic regression models. An exploratory analysis for patients on monotherapy was also conducted. RESULTS: Of 1059 ETN, 1327 ADA, and 581 JAKi initiators; 803 ETN, 984 ADA, and 361 JAKi initiators had 6 months' follow-up. JAKi initiators were older and had a relatively longer disease duration than ETN or ADA initiators (mean age: 61.3 vs 54.5 and 55.5 years; mean duration of RA: 8.1 vs 5.7 and 5.6 years). Unadjusted mean improvements in CDAI and PROs were similar between the groups at 6 months, except the proportion achieving LDA, remission, and MCID in CDAI, which were numerically higher in the ETN and ADA groups vs JAKi group (LDA: 43.4% and 41.9% vs 32.5%; remission: 18.2% and 15.1% vs 11.5%; MCID: 46.5% and 47.8% vs 38.0%). Adjusted effectiveness results did not reveal statistically significant differences between treatment groups at 6 months, with an exception in MCID (odds ratio [95% CI] for JAKi vs ETN: 0.65 [0.43-0.98]). At 6 months, 68.2% of ETN, 68.5% of ADA, and 66.5% of JAKi initiators remained on therapy. The findings at 12 months' follow-up and sensitivity analysis among monotherapy initiators also showed no differences in effectiveness outcomes between the groups. CONCLUSIONS: This analysis of real-world data from the CorEvitas RA Registry did not show differences in clinical effectiveness and treatment persistence rates in b/tsDMARD-naïve patients initiating ETN, ADA, or JAKi as first-line targeted therapy either alone or in combination with csDMARDs.

OBJECTIVE: Real-world studies assessing treatment response by psoriatic arthritis (PsA) domains are limited. This study aimed to describe the patient characteristics, frequency and combinations of disease domains, disease activity, and patient-reported outcomes (PROs) by PsA domains in patients who initiated treatment with a tumor necrosis factor inhibitor (TNFi) or interleukin-17 inhibitor (IL-17i). METHODS: Adults with PsA who initiated treatment with a TNFi or an IL-17i between January 2013 and January 2021 and had a 6 (±3)-month follow-up were included. The prevalence of PsA domains, the most common domain combinations, treatment persistence, and unadjusted change in disease activity and PROs from baseline to 6 months for each PsA domain were summarized descriptively. RESULTS: Of the 1005 eligible patients, 63% were receiving TNFi and 37% were receiving IL-17i. Forty percent of TNFi and 14% of IL-17i initiators received these treatments as first-line therapy. Peripheral arthritis and skin disease were the most common PsA domains identified in 86% and 82% of patients, respectively, and the triad of peripheral arthritis, skin disease, and nail psoriasis was the most common domain combination observed in 14% of patients. More than two thirds (68%) of patients remained on therapy at 6 months' follow-up. Improvements in disease activity and PROs were observed across all PsA domains in those receiving TNFi or IL-17i. CONCLUSION: This real-world analysis highlights the heterogeneity in domain presentation; therefore, assessing all PsA domains is important for optimal disease management. Improvements in outcomes across all PsA domains demonstrate the effectiveness of TNFi and IL-17i in diverse patient groups exhibiting different phenotypes of PsA.
RESUMEN
OBJECTIVE: We used the Study of Etanercept And Methotrexate in Combination or as Monotherapy in Subjects with Psoriatic Arthritis (SEAM-PsA) data set to examine the impact of presence of enthesitis, dactylitis, nail disease and/or psoriasis on treatment response in patients with early psoriatic arthritis (PsA). METHODS: This post hoc analysis evaluated the effect of baseline Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index (EI), Leeds Enthesitis Index (LEI), Leeds Dactylitis Index (LDI), modified Nail Psoriasis Severity Index (mNAPSI) scores and body surface area (BSA) on composite outcomes of minimal disease activity (MDA) responses, Psoriatic Arthritis Disease Activity Score (PASDAS) low disease activity (LDA), PASDAS changes and Good Responses and Disease Activity Index for Psoriatic Arthritis (DAPSA) scores at Week 24. RESULTS: Overall, 851 patients completed the SEAM-PsA trial and were included in the analysis. Baseline enthesitis (SPARCC EI>0 vs SPARCC EI=0 or LEI>0 vs LEI=0) was not associated with improved outcomes. Baseline dactylitis (LDI>0 vs LDI=0) was positively associated with improved MDA (OR: 1.4, p=0.0457), PASDAS LDA (OR: 1.8, p=0.0014) and Good Responses (OR: 1.6, p=0.0101) and greater reductions in PASDAS (estimate: -0.9, p<0.0001) and DAPSA scores (estimate: -3.8, p=0.0155) at Week 24. Similarly, baseline nail disease (mNAPSI >1 vs mNAPSI≤1) was positively associated with improved MDA (OR: 1.8, p=0.0233) and PASDAS LDA (OR: 1.8, p=0.0168) responses and greater reduction in PASDAS (estimate: -0.7, p=0.0005) at Week 24. CONCLUSIONS: Results from our analysis suggest that presence of dactylitis and nail disease, but not enthesitis, are associated with improved outcomes in patients with early PsA who were treated with methotrexate and/or etanercept.

INTRODUCTION: The magnitude and frequency of temporally related methotrexate (MTX)-associated side effects in rheumatoid arthritis (RA) or psoriatic arthritis (PsA) patients are difficult to quantify using traditional research methods. As proof of concept designed in part to implement digital data collection for remote patient monitoring, we conducted a study implementing self-controlled case series analytic methods to understand MTX-related symptoms in RA or PsA. METHODS: In study phase 1, adults with RA or PsA from the ArthritisPower® Registry (past or current oral MTX users) participated in a cross-sectional survey. In phase 2, current MTX users participated in a longitudinal study and completed the Patient-Reported Outcomes Measurement Information System (PROMIS®) 1-day nausea/vomiting and fatigue measure. Within-person change in PROMIS scores between risk (6-36 h post-dose) and control (96-144 h post-dose) windows were compared using mixed models. RESULTS: The baseline survey was completed by 671 participants (mean age: 54 years, 88% female, 92% white, 79% with RA). Among current MTX users (353/671 [53%]), most reported MTX-associated side effects (216/353 [61%]), most frequently fatigue (161/353 [46%]). Among phase 2 participants with (n = 39) and without (n = 84) baseline nausea, mean increase in PROMIS nausea was 5.1 units (P < 0.0001) and 0.7 units (P = 0.135), respectively; among those with (n = 51) and without (n = 72) baseline fatigue, mean increase in PROMIS fatigue was 3.9 units (P = 0.0003) and 0.4 units (P = 0.554), respectively. CONCLUSIONS: Digital remote patient monitoring presents an opportunity to detect and address medication tolerability in real time. Using a novel study design to control for between-person confounding, the magnitude of nausea and fatigue experienced by participants with RA and PsA temporally related to weekly MTX use was substantial.
RESUMEN
OBJECTIVES: We examined patient-reported outcomes (PROs) in The Study of Etanercept And Methotrexate in Patients with Psoriatic Arthritis (PsA); a 48-week, phase 3, randomised controlled trial that compared outcomes with methotrexate (MTX) monotherapy, etanercept monotherapy, and MTX+ etanercept in patients with PsA. METHODS: Efficacy endpoints included: mean changes from baseline and proportion of patients who reported improvements≥minimal clinically important difference (MCID) at week 24 in treatment groups for Health Assessment Questionnaire-Disability Index, Patient Global Assessment (PtGA), Patient Global Assessment of Joint Pain (PtGAJP) and Medical Outcomes Study Short Form-36 Questionnaire (SF-36) Physical Component Summary (PCS), and Mental Component Summary, and eight domain scores. PROs were analysed as reported (observed), without multiplicity adjustment; therefore, p values are descriptive. RESULTS: At week 24, patients receiving etanercept monotherapy or MTX+ etanercept combination reported greater improvements (p≤0.05) in PtGA, PtGAJP and SF-36 PCS scores compared with those receiving MTX monotherapy. Compared with MTX monotherapy, higher proportions of patients receiving etanercept monotherapy and combination therapy reported improvements≥MCID in PtGA (etanercept vs MTX, p=0.005) and PtGAJP (MTX +etanercept vs MTX, p=0.038). Across PROs, proportions of patients reporting scores≥age and gender-matched normative values at week 24 ranged from 20.8% to 51.0% with MTX monotherapy, 30.9% to 48.8% with etanercept monotherapy, and 30.6% to 52.3% with MTX+ etanercept combination. CONCLUSIONS: Patients receiving etanercept monotherapy or MTX+ etanercept reported greater improvements from baseline in several PROs compared with those receiving MTX monotherapy. PROs should be incorporated in discussions between patients and clinicians regarding their treatment choices as they can help determine which treatments are more beneficial in patients with PsA.

OBJECTIVES: To examine which composite measures are most sensitive to change when measuring psoriatic arthritis (PsA) disease activity, analyses compared the responsiveness of composite measures used in a 48-week randomized, controlled trial of MTX and etanercept in patients with PsA. METHODS: The trial randomised 851 patients to receive weekly: MTX (20 mg/week), etanercept (50 mg/week) or MTX plus etanercept. Dichotomous composite measures examined included ACR 20/50/70 responses, minimal disease activity (MDA) and very low disease activity (VLDA). Continuous composite measures examined included Disease Activity Score (28 joints) using CRP (DAS28-CRP), Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), Disease Activity for Psoriatic Arthritis (DAPSA) and Psoriatic Arthritis Disease Activity Score (PASDAS). RESULTS: At week 24, etanercept-treated groups were significantly more effective than MTX monotherapy to achieve ACR 20 (primary end point) and MDA (key secondary end point). When examining score changes from baseline at week 24 across the five continuous composite measures, PASDAS demonstrated relatively greater changes in the etanercept-treated groups compared with MTX monotherapy and had the largest effect size and standardized response. Joint count changes drove overall score changes at week 24 from baseline in all the continuous composite measures except for PASDAS, which was driven by the Physician and Patient Global Assessments. CONCLUSION: PASDAS was the most sensitive continuous composite measure examined with results that mirrored the protocol-defined primary and key secondary outcomes. Composite measures with multiple domains, such as PASDAS, may better quantify change in PsA disease burden. TRAIL REGISTRATION: https://ClinicalTrials.gov, number NCT02376790.

Background: Patients with moderate-to-severe psoriasis can have symptoms resulting in significant impact on patient-reported outcomes (PROs). The effect of etanercept (ETN) in moderate-to-severe psoriasis patients who previously received apremilast (APR) was studied, including impact on PRO endpoints. Methods: In this multicenter, open-label, single-arm, phase 4 estimation study, patients with moderate-to-severe psoriasis who did not have adequate response to APR in the opinion of the investigator received ETN 50mg subcutaneous (SC) twice weekly for 12 weeks, followed by ETN 50mg SC once weekly for an additional 12 weeks. Analysis was conducted for PROs directly and by the Psoriasis Area and Severity Index (PASI) achievement thresholds. Results: Of the 80 patients enrolled, the Psoriasis Symptom Inventory (PSI; total and individual items) had substantial improvement at weeks 12 and 24. Improvement in PSI total score (percent; mean [SD]) in patients who achieved PASI 50, -75, and -90 at week 12 was 57% (30), 67% (24), and 83% (18), respectively and at week 24 was 56% (40), 68% (29), and 80% (25). DLQI responders by PASI 50, -75, and 90 achievements were 69%, 68%, and 90%, respectively, at week 12 and 68%, 77%, and 82% at week 24. The percent of patients reported being "very satisfied" or "satisfied" with treatment at week 12 was 79%, 81%, and 100%, respectively, and at week 24 was 77%, 86%, and 88%. Conclusion: Patient-reported symptoms are important outcomes to consider in psoriasis management. ETN provided benefits in patients who did not have adequate response with APR, with improvements seen in both psoriasis symptoms and patient impact.

OBJECTIVE: To examine the efficacy of methotrexate monotherapy relative to etanercept monotherapy and the value of combining methotrexate and etanercept for the treatment of patients with psoriatic arthritis (PsA). METHODS: In this double-blind study, 851 patients with PsA were randomized to 1 of 3 treatment arms, as follows: oral methotrexate (20 mg) plus subcutaneous placebo given weekly (n = 284), subcutaneous etanercept (50 mg) plus oral placebo given weekly (n = 284), or subcutaneous etanercept (50 mg) plus oral methotrexate (20 mg) given weekly (combination therapy; n = 283). The American College of Rheumatology 20% improvement (ACR20) response and Minimal Disease Activity (MDA) response at week 24 were the primary end point and key secondary end point, respectively. Other measures of inflammatory arthritis, radiographic progression, and nonarticular disease manifestations were also assessed. RESULTS: Patients with PsA had a mean ± SD age of 48.4 ± 13.1 years, and the mean ± SD duration of PsA was 3.2 ± 6.3 years (median 0.6 years). ACR20 and MDA response rates at week 24 were significantly greater in patients who received etanercept monotherapy compared with those who received methotrexate monotherapy (ACR20, 60.9% versus 50.7% of patients [P = 0.029]; MDA, 35.9% versus 22.9% of patients [P = 0.005]), and both were significantly greater in the combination therapy group compared with the methotrexate monotherapy group at week 24 (ACR20, 65.0% versus 50.7% of patients [P = 0.005]; MDA, 35.7% versus 22.9% of patients [P = 0.005]). Other secondary outcomes (ACR50 and ACR70 response rates, proportions of patients achieving a Very Low Disease Activity score, and PsA disease activity scores) showed between-group differences that were consistent with the primary and key secondary end point results. Furthermore, patients in both etanercept treatment arms showed less radiographic progression at week 48 compared with patients who received methotrexate monotherapy. Outcomes were similar in the combination therapy and etanercept monotherapy groups, except for some skin end points. No new safety signals were seen. CONCLUSION: Etanercept monotherapy and combination therapy with etanercept and methotrexate showed greater efficacy than methotrexate monotherapy in patients with PsA, according to the ACR and MDA response rates and extent of radiographic progression at follow-up. Overall, combining methotrexate and etanercept did not improve the efficacy of etanercept.

BACKGROUND/OBJECTIVE: Compared with the adult psoriasis population, knowledge about the incidence of comorbidities in the pediatric psoriasis population is limited. The objective of this study was to assess the prevalence and incidence of comorbidities, including psychiatric comorbidities, in patients with pediatric psoriasis. METHODS: In this claims-based, retrospective cohort study, patients with pediatric psoriasis were matched 1:3 with a nonpsoriasis cohort based on age, sex, and index date (the earliest of inpatient claims or the latter of two outpatient claims). RESULTS: Obesity, serious infection, and juvenile idiopathic arthropathy had higher prevalence and incidence rates in the psoriasis cohort than the nonpsoriasis cohort. Psychiatric comorbidities were also more common in the psoriasis cohort than the nonpsoriasis cohort, as were ulcerative colitis and Crohn disease. Stratifying the psoriasis cohort by disease severity-mild and moderate-to-severe-found no differences in incidence rates of comorbidities between the two subsets. CONCLUSION: The incidence rates of many comorbid conditions were higher for patients with pediatric psoriasis compared with patients without pediatric psoriasis, and similar between patients with moderate-to-severe and mild pediatric psoriasis.

INTRODUCTION: Response to etanercept therapy in patients who have failed apremilast therapy has not been well characterized. METHODS: In this multicenter, open-label, single-arm, phase 4, estimation study, subjects with moderate to severe plaque psoriasis received etanercept 50 mg SC twice weekly for 12 weeks, followed by etanercept 50 mg SC once weekly for an additional 12 weeks. Subjects had BSA greater than equal to 10%, PASI greater than equal to 10, and sPGA greater than equal to 3 at screening and baseline; and had failed apremilast-because of either failure to achieve or loss of adequate clinical response, or intolerability to apremilast in the opinion of the investigator. Primary endpoint was PASI 75 at week 12. Secondary endpoints included PASI 75 at week 24, PASI 90 at weeks 12 and 24, and patient-reported outcomes: Psoriasis Symptom Inventory (PSI) score (total and individual items) at baseline and weeks 12 and 24, and over time; DLQI responder analysis (5-point improvement in DLQI from baseline or score of 0) at weeks 12 and 24; and patient assessment of treatment satisfaction at baseline and weeks 12 and 24. RESULTS: Among 80 patients, PASI 75 at weeks 12 and 24 was 41.6% (95% CI, 30.4%-53.4%) and 45.5% (34.1%-57.1%), respectively; PASI 90 was 13.0% (6.4%-22.6%) and 22.1% (13.4%-33.0%), respectively. Mean total PSI score (LOCF) improved from 16.6 (95% CI, 15.1-18.0) at baseline to 8.8 (7.3-10.2) and 9.6 (7.9-11.4) at weeks 12 and 24, respectively; improvements in item PSI scores were similar. The percentage of DLQI responders was 66.2% (95% CI, 54.3%-76.8%) and 57.3% (45.4%-68.7%) at weeks 12 and 24, respectively. The percentage of subjects who were satisfied/very satisfied with their psoriasis treatment improved from 5.0% at baseline to 60.8% and 53.3% at weeks 12 and 24, respectively. During the 24-week study, 23.8% and 2.5% of subjects reported an adverse event and serious adverse event, respectively; there were no new safety signals in this study. DISCUSSION: In patients who have failed apremilast, etanercept may represent an effective therapeutic option.

OBJECTIVES: The Psoriasis Symptom Inventory (PSI) is a patient-reported outcome instrument that measures the severity of psoriasis signs and symptoms. This study evaluated measurement properties of the PSI in patients with moderate to severe plaque psoriasis. METHODS: This secondary analysis used pooled data from a phase 3 brodalumab clinical trial (AMAGINE-1). Outcome measures included the PSI, Psoriasis Area and Severity Index (PASI), static Physician's Global Assessment (sPGA), psoriasis-affected body surface area, 36-item Short-Form Health Survey version 2, and the Dermatology Life Quality Index (DLQI). The PSI was evaluated for dimensionality, item performance, reliability (internal consistency and test-retest), construct validity, ability to detect change, and agreement between PSI response and response measures based on the PASI, sPGA, and DLQI. RESULTS: Results supported unidimensionality, good item fit, ordered responses, and PSI scoring. The PSI demonstrated reliability: baseline Cronbach's alpha ≥ 0.92 and intraclass correlation coefficients ≥ 0.95. Correlations between PSI total score and DLQI item 1 (r = 0.86), DLQI symptoms and feelings (r = 0.87), and 36-item Short-Form Health Survey version 2 bodily pain (r = -0.61) supported convergent validity. PSI scores differed significantly (P < 0.001) among severity groups based on the PASI (< 12/≥ 12), sPGA (0-1/2-3/4-5), body surface area (< 5%/5%-10%/> 10%), and DLQI (≤ 5/> 5) at weeks 8 and 12. At week 12, the PSI detected significant changes in severity based on PASI responses (< 50/50- < 75/≥ 75) and sPGA (0-1/≥ 2), and showed good agreement (k ≥ 0.66) between PSI response and PASI, sPGA, and DLQI responses. CONCLUSION: The PSI demonstrated excellent validity, reliability, and ability to detect change in the severity of psoriasis signs and symptoms.

BACKGROUND: OBSERVE-5 was a 5-year Food and Drug Administration-mandated surveillance registry of patients with psoriasis. OBJECTIVE: We sought to assess long-term etanercept safety and effectiveness. METHODS: Patients with moderate to severe psoriasis enrolled; a single baseline dose of etanercept was required. Key outcome measures included serious adverse events, serious infectious events, events of medical interest, psoriasis-affected body surface area, physician global assessment score, and Dermatology Life Quality Index score. Safety outcomes were assessed relative to data from the MarketScan database. RESULTS: For 2510 patients, 5-year cumulative incidence was 22.2% (95% confidence interval [CI] 20.3%-24.2%) for serious adverse events; 6.5% (95% CI 5.4%-7.7%) for serious infectious events; 3.2% (95% CI 2.3%-4.1%) for malignancies excluding nonmelanoma skin cancer; 3.6% (95% CI 2.7%-4.5%) for nonmelanoma skin cancer; 2.8% (95% CI 2.0%-3.6%) for coronary artery disease; 0.7% (95% CI 0.3%-1.2%) for psoriasis worsening; 0.2% (95% CI 0.0%-0.4%) for central nervous system demyelinating disorder; 0.1% (95% CI 0.0%-0.3%) for lymphoma and for tuberculosis; and 0.1% (95% CI 0.0%-0.2%) for opportunistic infection and for lupus; 55 fatal events were reported. Rates of malignancies, lymphomas, nonmelanoma skin cancer, and hospitalization-associated infections were not higher than expected relative to administrative claims data. The percentage of patients rated as clear/almost clear was 12% at baseline, which increased to 51% at month 6 and remained relatively stable throughout 5 years. LIMITATIONS: No internal comparator group was included; rare events may not have been detected. CONCLUSION: No new safety signals were observed with long-term, real-world etanercept use.

BACKGROUND: Etanercept is approved for the treatment of chronic moderate to severe plaque psoriasis in adults. OBJECTIVE: We sought to evaluate the long-term safety of etanercept in a real-world clinical setting. Assessment of etanercept efficacy was a secondary objective. METHODS: OBSERVE-5 is a 5-year observational safety registry initiated in May 2006 at multiple sites in the United States and Canada. Data collection includes the number of serious adverse events, serious infectious events, and prespecified events of medical interest. Efficacy data include body surface area assessments, physician and patient global assessments of psoriasis, and the Dermatology Life Quality Index. This interim analysis presents data from the first 3 years of the follow-up period. RESULTS: A total of 2511 patients were enrolled. Of 1890 patients continuing in the registry after 3 years, 113 were inactive for 1 to 2 years, and 115 were inactive for longer than 2 years. The 3-year incidence proportions of serious adverse events and serious infectious events based on Kaplan-Meier methodology were 0.14 and 0.04, respectively. The observed numbers of patients experiencing lymphoma, serious infectious events requiring hospitalization, nonmelanoma skin cancer, and malignancies excluding nonmelanoma skin cancer were not higher than the expected number of cases estimated from a large US administrative health claims database. LIMITATIONS: The registry lacks a control group, and the study is too small to measure the frequency of rare events. CONCLUSION: Etanercept demonstrated good tolerability in patients with plaque psoriasis in the clinical setting in this interim analysis. No new or unexpected safety concerns were observed.

BACKGROUND: A retrospective study utilizing administrative claims from a US commercial health plan was performed to examine etanercept and adalimumab treatment patterns among patients with psoriasis (PSO). METHODS: Biologic-naïve PSO patients initiating etanercept or adalimumab therapy between 18 January 2008 and 31 December 2008 were identified. Patients continuously enrolled in the health plan for 6 months before and ≥12 months after therapy initiation were followed until disenrollment from the plan or 31 December 2009. Persistence was defined as continuous use of index TNF blocker without a gap in therapy ≥60 days. Patients with gaps in index therapy ≥60 days were classified as discontinuing, switching, or restarting the index therapy. RESULTS: In total, 497 patients initiated etanercept and 330 the adalimumab therapy. Mean age for both groups was 43 years. Approximately 40-42% of patients were persistent on their index TNF blocker for 1 year. Among patients with a ≥60-day gap in therapy, discontinuation without restart or switch occurred in 37% of etanercept and 45% of adalimumab patients (p = 0.04). Differences in therapy restart or switching between the groups were not statistically significant. CONCLUSIONS: TNF-blocker therapy persistence is low among PSO patients in this health plan.

Although the histological changes seen in psoriasis have long been well characterized, the underlying cellular and molecular mechanisms have only begun to be elucidated over the past 20 years. Proinflammatory factors such as tumor necrosis factor (TNF)-α have a central role in psoriasis pathogenesis, and many T-helper 1 (Th1) cytokines and messenger RNAs are elevated in psoriatic lesions. IL-17A, IL-17F, and other Th17 cell-derived cytokines have been shown in murine models to induce features that mimic human psoriasis. This review focuses on the emerging biology of the IL-17 cytokine family in psoriasis, and on the molecular and genetic information gained from animal models and human clinical studies that confirm IL-17 as a crucial proinflammatory cytokine in psoriasis. Expression of IL-17A, IL-17C, and IL-17F is strikingly increased in psoriatic lesions, and successful therapy is associated with restoration of the expression of a wide range of genes (including effector molecules downstream of IL-17 such as cytokines, chemokines, and antimicrobial peptides) to near-normal levels. Therapeutic agents in development that target IL-17 are discussed, and an emerging model of the key role of IL-17 in the pathogenesis of psoriasis is presented.

OBJECTIVE: To develop and assess content validity of the Psoriasis Symptom Inventory (PSI), a patient-reported outcome (PRO) measure of psoriasis symptoms. METHODS: Following initial literature exploration and input from experts, concept elicitation was conducted in two rounds (focus groups and individual interviews) with 59 subjects with mild to severe psoriasis. Transcripts were coded to identify symptom concepts and develop a conceptual framework using ATLAS.ti software. Qualitative content analysis and clinical expert input supported item generation and development of a draft measure. Two rounds of face-to-face cognitive interviews with 40 subjects with moderate to severe psoriasis were conducted to test subject comprehension and content coverage. RESULTS: Concepts of itching, scaling, flaking, tearing/cracking, burning, stinging, pain, bleeding and color of appearance were the most common symptom-related expressions. Saturation of concept was demonstrated. Severity was identified as the most meaningful attribute of psoriasis symptoms. A final 8-item measure was developed to assess patient-perceived symptom severity for itch, pain, burning, stinging, cracking, scaling, flaking and redness. Twenty-four-hour recall and 7-day recall versions were prepared for future quantitative assessment of measurement properties. CONCLUSIONS: The PSI is a short, low burden, patient-reported measure of psoriasis symptom severity with documented evidence of content validity.

BACKGROUND: The objective of this study was to evaluate the measurement properties of the Psoriasis Symptom Inventory (PSI), an eight-item patient-reported outcome measure for assessing severity of plaque psoriasis symptoms. METHODS: In this prospective, randomized study using data from adults with moderate-to-severe plaque psoriasis, patients completed the PSI, Dermatology Life Quality Index (DLQI), SF-36v2 Acute, and Patient Global Assessment (PtGA). PSI construct validity was assessed using Spearman rank correlations between PSI and DLQI and SF-36; test-retest reliability and sensitivity to change were evaluated using PtGA as an anchor. Daily 24-h and weekly 7-day PSI versions were evaluated. RESULTS: Eight US sites enrolled 143 patients; 139 (97.2%) completed the study. All symptoms (itch, redness, scaling, burning, cracking, stinging, flaking, and pain) were reported across all response options (not at all severe, mild, moderate, severe, very severe). Test-retest reliability was acceptable (intraclass correlation coefficients range = 0.70-0.80). A priori hypotheses of convergent and discriminant validity were confirmed by correlations of PSI with DLQI items and SF-36 domains. The PSI demonstrated good construct validity and was sensitive to within-subject change (p < 0.0001). CONCLUSIONS: The PSI is brief, valid, reproducible, and responsive to change and has the potential to be a useful PRO measure in psoriasis clinical trials.

BACKGROUND: In this phase 2, randomized, double-blind, placebo-controlled, dose-ranging study, we assessed the efficacy and safety of brodalumab (AMG 827), a human anti-interleukin-17-receptor monoclonal antibody, for the treatment of moderate-to-severe plaque psoriasis. METHODS: We randomly assigned patients with a score of 12 or higher on the psoriasis area-and-severity index (PASI, on which scores range from 0 to 72, with higher scores indicating more severe disease) and with 10% or more of their body-surface area affected by psoriasis to receive brodalumab (70 mg, 140 mg, or 210 mg at day 1 and weeks 1, 2, 4, 6, 8, and 10 or 280 mg monthly) or placebo. The primary end point was the percentage improvement from baseline in the PASI score at week 12. Secondary end points included improvement of at least 75% and at least 90% in the PASI score and the score on the static physician's global assessment at week 12. RESULTS: A total of 198 patients underwent randomization. At week 12, the mean percentage improvements in the PASI score were 45.0% among patients receiving 70 mg of brodalumab, 85.9% among those receiving 140 mg, 86.3% among those receiving 210 mg, 76.0% among those receiving 280 mg, and 16.0% among those receiving placebo (P<0.001 for all comparisons with placebo). An improvement of at least 75% and at least 90% in the PASI score at week 12 was seen in 77% and 72%, respectively, of the patients in the 140-mg brodalumab group and in 82% and 75%, respectively, of the patients in the 210-mg group, as compared with 0% in the placebo group (P<0.001 for all comparisons). The percentage of patients with a static physician's global assessment of clear or minimal disease was 26%, 85%, 80%, and 69% with the 70-mg, 140-mg, 210-mg, and 280-mg doses, respectively, of brodalumab, as compared with 3% with placebo (P<0.01 for all comparisons with placebo). Two cases of grade 3 neutropenia were reported in the 210-mg brodalumab group. The most commonly reported adverse events in the combined brodalumab groups were nasopharyngitis (8%), upper respiratory tract infection (8%), and injection-site erythema (6%). CONCLUSIONS: Brodalumab significantly improved plaque psoriasis in this 12-week, phase 2 study. (Funded by Amgen; ClinicalTrials.gov number, NCT00975637.).

BACKGROUND: Biologic therapies are used to treat moderate to severe psoriasis, but evidence from randomized, controlled studies is lacking regarding scalp-related effectiveness. OBJECTIVE: To evaluate the efficacy and safety of etanercept for scalp symptoms (erythema, induration, scale, and percentage of scalp involvement) in patients with moderate to severe plaque psoriasis and scalp involvement. METHODS: In this randomized, placebo-controlled study, adult patients with stable plaque psoriasis and significant scalp symptoms received etanercept 50 mg twice weekly (BIW) by subcutaneous injection (SC) for 12 weeks, followed by etanercept 50 mg once weekly (QW) and placebo QW (Group A, n = 62) or SC placebo BIW for 12 weeks, followed by etanercept 50 mg BIW for 12 weeks (Group B, n = 62). The primary end point was percentage change in Psoriasis Scalp Severity Index (PSSI) at week 12. RESULTS: Demographics and disease characteristics were balanced: 56% men, 73% white, median age 41 years, median BMI 30.2 kg/m(2). At week 12, mean PSSI improvement was 86.8% (standard deviation [SD], 18.0%) in Group A and 20.4% (SD, 39.3%) in Group B (P < .0001). At week 24, mean PSSI improvements were as follows: Group A, 90.6% (SD 13.1%); Group B, 79.1% (SD 33.6%). At week 12, 51 of 59 (86%) Group A patients and 7 of 61 (11%) Group B patients achieved PSSI 75 (P <.0001). Three patients (2.7%) reported 5 serious adverse events: cholecystitis/cholelithiasis, fall/rib fracture, and metastatic malignant melanoma. LIMITATIONS: The study was insufficiently powered to detect rare adverse events potentially associated with etanercept. CONCLUSIONS: Etanercept is an effective, well-tolerated treatment for plaque psoriasis involving the scalp.
