Evolution of Patient Perceptions of Psoriatic Disease : Results from the Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) Survey

Since the 2012 Multinational Assessment of Psoriasis and Psoriatic Arthritis (MAPP) survey, several systemic treatments for psoriasis (PsO) and/or psoriatic arthritis (PsA) have been approved. The population-based UPLIFT survey was conducted to understand how perceptions of treatment-related outcomes have evolved, particularly for patients with mild to moderate PsO and/or PsA and their dermatologists. This population- and web-based survey was conducted from 2 March to 3 June 2020, in North America, Europe, and Japan. Adults with self-reported healthcare practitioner (HCP)-diagnosed PsO and/or PsA and dermatologists who spent > 50% of time treating patients and treated ≥ 20 patients with PsO, including plaque PsO, per month were included. Patient participants were recruited at random from online panels; dermatologists were recruited randomly from representative physician panels. Of 264,054 patient responses, 3806 who self-reported an HCP diagnosis of PsO and/or PsA were included in the final sample; 67% had PsO alone, 28% had PsO and PsA, and 5% had PsA alone. The estimated population prevalence of psoriatic disease was 7% (PsO only: 4%; PsO and PsA: 2%; PsA only: 1%). Most patients (78%) reported PsO-involved body surface area (BSA) ≤ 3 palms, and ~ 90% or more reported itching, redness, flaking, and scales. Many PsO patients without diagnosed PsA reported musculoskeletal symptoms suggestive of PsA (63%). Across BSA categories, approximately one in four patients was not currently receiving treatment and > 50% had Dermatology Life Quality Index score > 5. Patients and dermatologists had different perceptions of PsO severity, office visit discussions, treatment goals, and treatment satisfaction. The survey was conducted during the coronavirus disease 2019 (COVID-19) pandemic, which could have affected assessments of patient-reported outcomes and ability to have in-person HCP visits. Patients with PsO and PsA in UPLIFT reported high disease burden, including patients with limited skin involvement. An opportunity exists to align patient and dermatologist perceptions to optimize management of PsO and PsA. The online version contains supplementary material available at 10.1007/s13555-021-00635-4.

27874 Correlation of itch response to roflumilast cream with disease severity and patient-reported outcomes in patients with chronic plaque psoriasis

Roflumilast cream is a nonsteroidal, selective phosphodiesterase-4 inhibitor in development for plaque psoriasis (PsO). A Phase 2b, double-blinded trial randomized adults with PsO (2-20% body surface area) to once daily roflumilast 0.3%, roflumilast 0.15%, or vehicle for 12 weeks (NCT03638258). Throughout the trial, itch and its impact were evaluated via patient reported outcomes (PROs): Worst Itch Numeric Rating Scale (WI–NRS), Itch related Sleep Loss (IRSL), and Dermatology Life Quality Index (DLQI). This posthoc analysis reports correlation of WI–NRS with other PROs and with disease severity. Overall, 331 patients were randomized (109 to roflumilast 0.3%, 113 to 0.15%, and 109 to vehicle). At baseline, the mean WI–NRS score was 5.87. Throughout the trial, both roflumilast doses showed similar improvements in WI–NRS starting at Week 2 and were significantly superior to vehicle (P ≤.002). At baseline, Pearson correlation coefficients (PCCs) for WI–NRS and Psoriasis Area and Severity Index (PASI) were 0.189, 0.282, 0.205 for roflumilast 0.3%, roflumilast 0.15%, and vehicle, respectively (P ≤.033 for all correlations); for WI–NRS and IRSL: 0.548, 0.646, 0.652 (P ˂.001); for WI–NRS and DLQI: 0.445, 0.617, 0.422 (P ˂.001). At Week 8, PCCs for WI–NRS and PASI were 0.420, 0.409, 0.365 (P ˂.001); for WI–NRS and IRSL: 0.673, 0.725, 0.696 (P ˂.001); for WI–NRS and DLQI: 0.607, 0.823, 0.529. Treatment with roflumilast resulted in rapid and robust improvement in the severity of itch associated with PsO. Itch response to roflumilast was independent of disease severity and positively correlated with patient-reported sleep loss and quality of life improvement

28043 Roflumilast cream significantly improves chronic plaque psoriasis in patients with steroid-sensitive area involvement

Roflumilast cream is a nonsteroidal, selective phosphodiesterase-4 inhibitor in development for plaque psoriasis (PsO). A double-blind, phase 2b trial randomized adults with PsO to once daily roflumilast 0.3%, 0.15%, or vehicle for 12 weeks (NCT03638258).(1) Efficacy was assessed using Investigator Global Assessment (IGA), Worst Itch Numeric Rating Scale (WI–NRS), and Psoriasis Symptom Diary (PSD). This posthoc analysis reports efficacy and safety in patients with steroid-sensitive area involvement (plaques on the face, neck, or in intertriginous areas). Of 331 patients, 160 had steroid-sensitive area involvement. The primary endpoint in the study, IGA status clear/almost clear at Week 6 was met by 27.2% patients with steroid sensitive areas (P =.007 vs vehicle), 22.3% (P =.026), and 6.3% on roflumilast 0.3%, roflumilast 0.15%, and vehicle, respectively; relative to 30.1% (P =.026), 24.1% (P =.098), and 12.0% patients without steroid-sensitive areas. Among patients with baseline WI–NRS score ≥4, 73.5%, 55.6%, and 32.6% of those with steroid-sensitive areas and 45.9%, 72.7%, and 23.7% of those without steroid-sensitive areas achieved a 4-point reduction with roflumilast 0.3%, 0.15%, or vehicle at Week 12. PSD improvement from baseline at Week 12 for patients with steroid-sensitive areas was -48.3 (P ˂.001), -43.1 (P =.012), and -24.9, and for patients without steroid-sensitive areas -35.7 (P =.003), -44.6 (P ˂.001), and -17.1. Most treatment emergent adverse events were mild to moderate and there was no evidence of local irritation. Once-daily roflumilast cream was well tolerated with significant improvements in investigator and patient assessed PsO outcomes in patients with steroid-sensitive area involvement on the face, neck, or intertriginous areas

Psychometric validation of the generalized pustular psoriasis physician global assessment (GPPGA) and generalized pustular psoriasis area and severity index (GPPASI)

Background: Generalized pustular psoriasis (GPP) is a rare and life-threatening skin disease often accompanied by systemic inflammation. There are currently no standardized or validated GPP-specific measures for assessing severity. Objective: To evaluate the reliability, validity, and responder definitions of the generalized pustular psoriasis physician global assessment (GPPGA) and generalized pustular psoriasis area and severity index (GPPASI). Methods: The GPPGA and GPPASI were validated using outcome data from Week 1 of the Effisayil™ 1 study. The psychometric analyses performed included confirmatory factor analysis, item-to-item/item-to-total correlations, internal consistency reliability, test-retest reliability, convergent validity, known-groups validity, responsiveness analysis, and responder definition analysis. Results: Using data from this patient cohort (N=53), confirmatory factor analysis demonstrated unidimensionality of the GPPGA total score (root mean square error of approximation <0.08), and GPPGA item-to-item and item-to-total correlations ranged from 0.58–0.90. The GPPGA total score, pustulation subscore, and GPPASI total score all demonstrated good test-retest reliability (intraclass correlation coefficient: 0.70, 0.91, and 0.95, respectively), and good evidence of convergent validity. In anchor-based analyses, all three scores were able to detect changes in symptom and disease severity over time; reductions of -1.4, -2.2, and -12.0 were suggested as clinically meaningful improvement thresholds for the GPPGA total score, GPPGA pustulation subscore, and GPPASI total score, respectively. Anchor-based analyses also supported the GPPASI 50 as a clinically meaningful threshold for improvement. Conclusions: Overall, our findings indicate that the GPPGA and GPPASI are valid, reliable, and responsive measures for the assessment of GPP disease severity, and support their use in informing clinical endpoints in trials in GPP

Biological treatment for psoriasis and the risk of herpes zoster: Results from the Psoriasis Longitudinal Assessment and Registry (PSOLAR).

PURPOSE: To describe the risk of herpes zoster (HZ) in patients with psoriasis and its relation to non-biologic systemic therapies or biologic treatment. MATERIALS AND METHODS: Psoriasis Longitudinal Assessment and Registry (PSOLAR) is an international, prospective, registry that follows adult patients with psoriasis eligible to receive non-biologic systemic therapies or biologic therapies. Mutually exclusive therapy cohorts were defined. HZ incident rates were calculated for each therapy cohort and rates between cohorts were compared using hazard ratios (HR) adjusted for potential confounders, in new users and prevalent-exposure patients. RESULTS: A total of 55 HZ events were identified in 10,469 patients in PSOLAR. The adjusted hazard ratio in the overall study population (new user and prevalent-exposed patients) was 2.22 (95% CI: 0.82-5.97; p = 0.116) for tumor necrosis factor-alpha (TNF) inhibitors, 2.73 (0.98-7.58; p = 0.054) for ustekinumab, and 1.04 (0.20-5.41; p = 0.966) for methotrexate vs. reference (combined phototherapy, systemic steroids, topical therapy, and immunomodulators other than methotrexate). CONCLUSIONS: Exposure to ustekinumab, TNF-alpha inhibitors, and methotrexate was not associated with a statistically significant increased risk of HZ. However, HRs were elevated for ustekinumab and TNF-alpha inhibitors; a larger number of herpes zoster events would be needed to assess the presence or absence of risk

Psychometric validation of the Psoriasis Symptom Scale, Functional Assessment of Chronic Illness Therapy–Fatigue and pain‐Visual Analogue Scale in patients with generalized pustular psoriasis

Background: Generalized pustular psoriasis (GPP) is a rare, chronic, inflammatory skin disease associated with considerable patient burden. The Psoriasis Symptom Scale (PSS), Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-Fatigue) and pain-Visual Analogue Scale (pain-VAS) are patient-reported outcomes (PROs) that have not yet been validated in patients with GPP. Objectives: To evaluate the psychometric properties of the PSS, FACIT-Fatigue and pain-VAS using data from Effisayil 1, a randomised trial of spesolimab in patients with moderate-to-severe GPP. Methods: Inter-item correlations and confirmatory factor analysis (CFA) were performed using Week 1 data. Internal consistency was assessed with Cronbach's α coefficient using baseline and Week 1 data. Test–retest reliability was assessed using intraclass correlation coefficients (ICCs); change data for the GPP Physician Global Assessment total score and pustulation subscore were used to define a stable population. Convergent validity was assessed at baseline and Week 1 using Spearman's rank-order correlations. Known-groups validity was measured by analysis of variance using Week 1 data. Ability to detect change from baseline to Week 1 was evaluated by analysis of covariance. Results: Inter-item and item-to-total correlations were moderate or strong for most PSS and FACIT-Fatigue items. CFA demonstrated the unidimensionality of the PSS and FACIT-Fatigue, with high factor loadings for most items (PSS range, 0.75–0.94; FACIT-Fatigue range, 0.11–0.93) and acceptable fit statistics. Both scores demonstrated internal consistency (Cronbach's α, 0.71 and 0.95, respectively). The PSS, FACIT-Fatigue and pain-VAS demonstrated test–retest reliability (ICCs ≥0.70) and good evidence of convergent validity. Furthermore, the PROs could differentiate between known groups of varying symptom severity (range, p < 0.0001–0.0225) and detect changes in symptom severity from baseline to Week 1 (range, p < 0.0001–0.0002). Conclusions: Overall, these results support the reliability, validity and ability to detect change of the PSS, FACIT-Fatigue and pain-VAS as PROs in patients with GPP

Spesolimab treatment for the prevention of flares in people with generalized pustular psoriasis (GPP): a plain language summary of the Effisayil ™ 2 study

What is this study about?: Generalized pustular psoriasis (shortened to GPP) is a rare, potentially life-threatening disease in which pus-filled blisters or pustules may suddenly form all over the body. The drug spesolimab has been approved to treat worsening GPP (known as flares) in many countries. However, it was not known if spesolimab could prevent the symptoms of GPP. This summary reports the results from a clinical study called Effisayil™ 2, that was done to understand if spesolimab was a safe and effective way to prevent flares in people with GPP. In the study, 123 participants, recruited in 20 different countries, were given one of three different doses of spesolimab (low, medium, or high) or a non-active medicine (placebo) over 48 weeks. What were the results?: Participants who received spesolimab had fewer GPP flares over the course of the 48-week study. Different doses of the drug were tested and compared to placebo, and a high dose of spesolimab worked better than low and medium doses. Using spesolimab also reduced the chance of developing skin symptoms, such as redness or pustules, and prevented quality of life getting worse over 48 weeks. While some participants experienced unwanted effects, they were mostly mild or moderate and most did not appear to be caused by spesolimab, or the dose at which it was given. What do the results of the study mean?: The results indicate that a high dose of spesolimab works well to prevent GPP flares and stop the disease getting worse. Health authorities are looking at the results of this study to decide if spesolimab can also be prescribed for the prevention of GPP flares

Study protocol of the global Effisayil 1 Phase II, multicentre, randomised, double-blind, placebo-controlled trial of spesolimab in patients with generalized pustular psoriasis presenting with an acute flare

Introduction: Generalized pustular psoriasis (GPP) is a rare, potentially life-threatening disease characterised by recurrent flares of widespread neutrophilic aseptic skin pustular eruption. Despite the availability of approved biologics for GPP in Japan, Taiwan and Thailand, associated evidence is largely based on uncontrolled studies in which acute flares were not directly assessed. Therefore, there is a high unmet need to investigate new rapid-acting effective treatments that resolve symptoms associated with acute GPP flares. A prior Phase I proof-of-concept study showed rapid improvements in skin and pustule clearance with a single intravenous dose of spesolimab, a novel anti-interleukin-36 receptor antibody, in patients presenting with an acute GPP flare. Here, we present the design and rationale of Effisayil 1, a global, Phase II, placebo-controlled study to evaluate the efficacy, safety and tolerability of spesolimab in patients presenting with an acute GPP flare. Methods and analysis: At least 51 patients with an acute GPP flare will be randomised 2:1 to receive a single 900 mg intravenous dose of spesolimab or placebo and followed for up to 28 weeks. The primary endpoint is a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation subscore of 0 (pustule clearance) at Week 1. The key secondary endpoint is a GPPGA score of 0 or 1 (clear or almost clear) at Week 1. Safety will be assessed over the study duration by the occurrence of treatment-emergent adverse events. Blood and skin biopsies will be collected to assess biomarkers. Superiority of spesolimab over placebo in the proportion of patients achieving the primary and key secondary endpoints will be evaluated. Ethics and dissemination: The study complies with the ethical principles of the Declaration of Helsinki, the International Council for Harmonisation’s Good Clinical Practice and local regulations. Ethics committee approvals have been obtained for each centre from all participating countries and are listed in online supplementary file 1. Primary results will be published in a peer-reviewed journal. Trial registration details: ClinicalTrials.gov identifier: NCT03782792; Pre-results
