The article discusses the real-world effectiveness and drug survival of guselkumab over a 3-year period in treating moderate-to-severe plaque psoriasis, including difficult-to-treat areas. Guselkumab, an anti-IL23 biologic, has shown superior efficacy compared to adalimumab in clinical trials, with sustained high levels of clinical response over 5 years of treatment. Real-life studies have confirmed the effectiveness and safety of guselkumab, particularly in difficult-to-treat areas like scalp, palmoplantar, and genital psoriasis. The study emphasizes the importance of being treatment-naive for achieving complete or almost complete clinical clearance at Week 52. [Extracted from the article]

Background: The term "super responder" identifies a group of patients who exhibit a rapid and optimal response to biological treatment compared to the overall treated population. The primary objective of our study is to characterize this subgroup of patients to enable the early identification of those who will respond most effectively to the proposed treatment while also evaluating clinical efficacy. Methods: This retrospective study evaluated 232 patients treated with guselkumab in monotherapy for at least 20 weeks between November 2018 and November 2023. Patients were divided into two groups: those who achieved complete clear skin (PASI = 0) during the first 20 weeks of treatment were defined as super responders (SRe) and non-super responders (nSRe) were the remaining patients. PASI was assessed at weeks 0, 4, and subsequently every eight weeks. Predictors of the SRe status were evaluated by univariate and multivariate logistic regression analyses. Results: The univariate analyses showed that patients with psoriatic arthritis at the baseline, bio-naïve patients, or those who had not received an interleukin (IL) 17 inhibitor as their last therapy before guselkumab administration were more likely to be super responders to the proposed treatment. Multivariate logistic analysis models suggested that the combination of psoriatic arthritis at the baseline and the bio-naïve condition was the strongest predictive model for the SRe status. At week 204, the main difference between the two groups concerned the achievement of PASI100, maintained by 86.8 of SRe compared to 62.8% of nSRe. Conclusions: The efficacy and safety of guselkumab are confirmed in our real-life experience. Identifying the SRe status will undoubtedly play a role in clinical practice and the therapeutic decision-making algorithm. [ABSTRACT FROM AUTHOR]

Introduction: Treating plaque psoriasis (PsO) with guselkumab (GUS) promotes skin clearance and is associated with improvements in health-related quality of life (HRQoL), anxiety, and depression. It is unclear whether improvements in patient-reported outcomes are due to resolution of skin symptoms or the direct result of GUS treatment. Methods: Two phase 3, placebo- and active-comparator-controlled studies randomized patients with moderate-to-severe PsO to GUS, placebo (crossing over to GUS at week 16), or adalimumab. Post hoc mediation analyses examined direct and indirect effects of GUS, versus adalimumab, on Dermatology Life Quality Index (DLQI) or Hospital Anxiety and Depression Scale (HADS) after adjusting for indirect effects mediated by skin clearance, evaluated via Psoriasis Area and Severity Index (PASI), to determine the direct effect of GUS on dermatology HRQoL, depression, and anxiety. Results: Compared with adalimumab, the natural direct effect (NDE) of GUS on change in DLQI from baseline was − 2.04 (P < 0.001), using PASI improvement as a mediator, indicating 89.2% of the total treatment effect was due to direct effects of GUS; using PASI 90 as a mediator, NDE of GUS was − 1.43 (P < 0.001), with 62.2% of the total treatment effect attributed to direct effects of GUS. Compared with adalimumab, 25.5% of change in HADS anxiety score was mediated through PASI improvement (NDE − 0.74; P = 0.002), indicating 74.5% of the total effect was independent of PASI improvement. Similarly, 24% of treatment effect was mediated through PASI 90 (NDE − 0.76; P = 0.002). Comparable proportions of the total improvement in HADS depression scores were due to direct and indirect effects of GUS mediated through PASI improvement (direct, 50.2%; indirect, 49.8%) or PASI 90 (direct, 59.5%; indirect, 40.5%). Conclusions: GUS-mediated improvements in anxiety, depression, and overall HRQoL are not solely mediated by resolution of PsO signs, suggesting GUS use has a potential direct effect on anxiety and depression.

Abstract Pityriasis Rubra Pilaris (PRP) is a rare papulosquamous inflammatory dermatosis with variable clinical presentation and poorly understood pathogenesis that often poses diagnostic and therapeutic challenges. Data on currently available treatment options are limited, particularly when facing refractory cases. Both ustekinumab, an interleukin‐12 (IL‐12) and IL‐23 inhibitor, and guselkumab, an IL‐23p19 inhibitor, target the Th‐17 axis and are well established treatment options in moderate to severe psoriasis. However, increasing evidence, mostly derived from case reports and supported by recent understanding of the role of Th‐17 axis in PRP, also favours the use of IL‐17/IL‐23 pathway inhibitors in this disease. We present an adult female patient with long history of recalcitrant PRP refractory to multiple treatment options. Although initial improvement with ustekinumab was achieved, late disease progression ensued, leading to transition to guselkumab with remarkable clinical response.

Guselkumab is an anti-interleukin-23 monoclonal antibody that is approved for plaque psoriasis and psoriatic arthritis. We present a case of a 28-year-old female patient with acute onset of guttate psoriasis after a blistering sunburn. She had no personal or family history of psoriasis or chronic inflammatory skin disease. The guttate psoriasis was refractory to topical treatment. After the first dose of guselkumab (100 mg subcutaneous injection), the patient experienced near-clearance of her guttate psoriasis, with continued improvement and drug-free remission 8 months after cessation of treatment. Dermatologists could consider guselkumab as a treatment option for patients with guttate psoriasis. Future studies should examine the potential for guselkumab to induce drug-free remissions in guttate psoriasis.

Purpose: Real-world data comparing long-term performance of interleukin (IL)-23 and IL-17 inhibitors in psoriasis are limited. This study compared treatment persistence and remission among patients initiating guselkumab versus IL-17 inhibitors. Methods: Adults with psoriasis initiating guselkumab, secukinumab, or ixekizumab treatment (index date) were identified from Merative™ MarketScan® Research Databases (01/01/2016–10/31/2021). Persistence was defined as no index biologic supply gaps of twice the labeled maintenance dosing interval. Remission was defined using an exploratory approach as index biologic discontinuation for ≥6 months without psoriasis-related inpatient admissions and treatments. Results: There were 3516 and 6066 patients in the guselkumab versus secukinumab comparison, and 3805 and 4674 patients in guselkumab versus ixekizumab comparison. At 18 months, the guselkumab cohort demonstrated about twice the persistence rate as secukinumab (hazard ratio [HR] = 2.15; p < 0.001) and ixekizumab cohorts (HR = 1.77; p < 0.001). At 6 months after index biologic discontinuation, the guselkumab cohort was 31% and 40% more likely to achieve remission than secukinumab (rate ratio [RR] = 1.31; p < 0.001) and ixekizumab cohorts (RR = 1.40; p < 0.001). Conclusions: Guselkumab was associated with greater persistence and likelihood of remission than IL-17 inhibitors, indicating greater disease control and modification potential.

In this case report, we present a 29-year-old patient with Down syndrome (DS) who manifested both psoriasis and hidradenitis suppurativa (HS) concurrently. The utilization of guselkumab, an interleukin 23 p19 subunit inhibitor that is approved for moderate to severe psoriasis vulgaris, resulted in significant improvement in symptoms for both conditions following the initial administration. The patient achieved a psoriasis area and severity index 90 response with significant amelioration of psoriatic plaques. Simultaneously, more than 50% improvement in abscess and inflammatory nodules secondary to HS was observed 4 weeks after the start of guselkumab therapy, resulting in a HiSCR score achievement. Throughout the 52-week follow-up, there were no observed exacerbations of symptoms or adverse effects. This case highlights the potential benefit of guselkumab in the simultaneous treatment of HS and psoriasis, and suggests that guselkumab is an effective and safe biologic agent of choice in individuals with DS, where the prevalence of both these diseases is increased, and treatment adherence may pose additional challenges compared to the normal population.

Objectives: Evaluate patterns of stringent disease control with 2 years of guselkumab across key disease-identified domains and patient-reported outcomes (PROs) in subgroups of patients with psoriatic arthritis (PsA) defined by baseline characteristics. Method: This post hoc analysis of DISCOVER-2 (Clinicaltrials.gov NCT03158285) evaluated biologic-naïve PsA patients (≥ 5 swollen/ ≥ 5 tender joints, C-reactive protein [CRP] ≥ 0.6 mg/dL) randomized to guselkumab every 4 weeks (Q4W); guselkumab at Weeks 0 and 4, then Q8W; or placebo with crossover to guselkumab Q4W at Week 24. Achievement of American College of Rheumatology 50/70% improvement (ACR50/70), Investigator's Global Assessment (IGA) 0, dactylitis/enthesitis resolution, Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue response (≥ 4-point improvement), HAQ-Disability Index (HAQ-DI) response (≥ 0.35-point improvement), PsA Disease Activity Score (PASDAS) low disease activity (LDA), and minimal disease activity (MDA) was assessed at Weeks 24, 52, and 100 in subgroups defined by sex and baseline medication use, body mass index, PsA duration, swollen/tender joints, CRP, and psoriasis severity/extent. Patients with missing categorical response data were considered nonresponders. Results: 442/493 (90%) guselkumab-randomized patients completed treatment through Week 100. Significant multi-domain efficacy of guselkumab versus placebo was shown across adequately sized patient subgroups. A pattern of continuous improvement was observed across key PsA domains and PROs within patient subgroups: 65%–85% of guselkumab-randomized patients had enthesitis/dactylitis resolution, 50%–70% achieved complete skin clearance, 60%–80% reported meaningful improvements in function/fatigue, 40%–65% achieved PASDAS LDA, and 35%–50% achieved MDA at Week 100. Conclusion: Patients with active PsA receiving guselkumab demonstrated durable achievement of stringent endpoints associated with disease control across key PsA domains and PROs, regardless of baseline characteristics. Key Points • Among biologic-naïve patients with highly active psoriatic arthritis (PsA), efficacy of guselkumab across stringent disease endpoints and patient-reported outcomes (PROs) at Week 24 was consistent regardless of baseline demographics and disease characteristics. • Within guselkumab-randomized PsA patient subgroups, major improvements in joint disease activity, complete skin clearance, dactylitis/enthesitis resolution, clinically meaningful improvements in PROs, and achievement of low overall disease activity were maintained through Week 100. • Durable stringent endpoint achievement indicating disease control was observed with guselkumab, regardless of baseline patient or disease characteristics.

Pityriasis rubra pilaris (PRP) is a rare and chronic inflammatory dermatologic condition characterized by hyperkeratotic salmon-colored plaques and palmoplantar keratoderma. Traditional therapeutic modalities have shown limited efficacy and often entail potential adverse effects, highlighting the need for alternative treatment options. Our review aims to summarize the current evidence on the off-label use of IL-23 inhibitors, risankizumab and guselkumab, in the treatment of PRP. These biologic agents have been approved for psoriasis, and their potential role in managing PRP has recently garnered interest. We conducted a comprehensive literature search on PubMed and Scopus databases, identifying relevant studies published in English up to June 2023 following PRISMA guidelines. A total of 10 studies were selected for data extraction and review. Results from the selected studies demonstrated encouraging outcomes with both risankizumab and guselkumab in managing PRP. Among 11 patients treated with risankizumab, 10 showed notable improvements in various disease manifestations, including pruritus, erythema, and affected body surface area. DLQI scores and BSA percentages reported a significant improvement before and after risankizumab treatment (p = 0.0322; p = 0.0216). However, two cases also reported symptom aggravation or even disease worsening. Patients treated with guselkumab exhibited ultimate improvement in all five cases, with complete clearance in three out of five cases. DLQI and BSA percentages also reported significant improvement with treatment with guselkumab (p = 0.0172; p < 0.0001). While most cases demonstrated positive outcomes, there were isolated instances of worsening symptoms, emphasizing the need for caution and further investigation. Further research with larger sample sizes and longer follow-up periods is necessary to establish the efficacy, optimal dosing, and long-term safety of risankizumab and guselkumab in treating PRP. Overall, we provide valuable insights into the potential use of IL-23 inhibitors, risankizumab, and guselkumab, as promising treatment options for PRP. These biologics have shown efficacy in improving symptoms in treatment-resistant cases, offering new avenues for clinicians to explore in the treatment of PRP. [ABSTRACT FROM AUTHOR]

Vitiligo is a chronic depigmenting disorder that significantly impacts the quality of life of patients. Though there have been significant advancements in targeted therapies in skin diseases such as psoriasis or eczema, the progress in the treatment of vitiligo has been slow, with minimal studies assessing the effect of biologics, though there has been recent evidence of the effectiveness of JAK inhibition. This paper reviews the published case reports and studies for the use of systemic targeted therapies including biologics and JAK inhibitors in vitiligo. [ABSTRACT FROM AUTHOR]

Introduction: Matching-adjusted indirect comparisons (MAIC) were used to assess the relative efficacy of bimekizumab 160 mg every 4 weeks (Q4W) compared to guselkumab 100 mg Q4W or every 8 weeks (Q8W) at 48/52 weeks in patients with psoriatic arthritis (PsA) who were biologic disease-modifying antirheumatic drug-naïve (bDMARD-naïve) or with previous inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR). Methods: Relevant trials were identified as part of a systematic literature review. For patients who were bDMARD-naïve, individual patient data (IPD) from BE OPTIMAL (N = 431) was matched to summary data from DISCOVER-2 (Q4W, n = 245; Q8W, n = 248). For patients who were TNFi-IR, IPD from BE COMPLETE (n = 267) and summary data from COSMOS (Q8W, N = 189). Trial populations were re-weighted using propensity scores. Unanchored comparisons of recalculated bimekizumab and guselkumab 48- or 52-week non-responder imputation outcomes for 20/50/70% improvement in American College of Rheumatology score (ACR20/50/70) and minimal disease activity (MDA) index were analyzed. Results: In patients who were bDMARD-naïve, bimekizumab was associated with a greater likelihood of ACR50 (odds ratio [95% confidence interval] 1.62 [1.07, 2.44]; p = 0.021), ACR70 (2.20 [1.43, 3.38]; p < 0.001), and MDA (1.82 [1.20, 2.76]; p = 0.005) compared to guselkumab Q4W at week 52. Bimekizumab also had a greater likelihood of ACR70 response (2.08 [1.34, 3.22]; p = 0.001) and MDA (2.07 [1.35, 3.17]; p < 0.001) compared to guselkumab Q8W at week 52. In patients who were TNFi-IR, bimekizumab had a greater likelihood in achieving all evaluated outcomes compared to guselkumab Q8W at week 48/52 (ACR20, 1.77 [1.15, 2.72]; p = 0.010; ACR50, 1.56 [1.03, 2.36]; p = 0.037; ACR70, 1.66 [1.05, 2.61]; p = 0.028; and MDA, 1.95 [1.27, 3.02]; p = 0.003). Conclusions: According to MAICs, bimekizumab demonstrated greater or comparable efficacy on ACR50/70 and MDA outcomes than guselkumab in patients with PsA who were bDMARD-naïve and TNFi-IR at week 48/52. Bimekizumab had a more favorable likelihood than guselkumab in achieving more stringent treatment outcomes. Trial Registrations: NCT03895203, NCT03896581, NCT04009499, NCT03158285, NCT03796858.

Introduction: Guselkumab is an interleukin-23 (IL-23) inhibitor licensed for the treatment of psoriatic arthritis (PsA). This study aimed to evaluate the 6-month effectiveness of guselkumab in patients with PsA in a "real-life" multicentre patient cohort. We also estimated the drug retention rate (DRR) of gusulkumab, also assessing the impact of comorbidities and patient clinical characteristics, in a collective 18-month prospective follow-up. Methods: Between December 2021 and September 2023, consecutive patients with PsA were evaluated if treated at least for 6 months with guselkumab in a prospective multicentre study to evaluate the effectiveness of the drug by means of disease activity index for psoriatic arthritis (DAPSA) and cumulative DRR. Results: A total of 111 patients with PsA were evaluated and treated with guselkumab (age 56.8 ± 9.9, male sex 20.7%). These patients were mainly characterised by active and long-standing PsA with median disease duration of 6.0 (7.0) years (55.9% disease duration ≥ 5 years), 55.0% showed comorbidities, 78.4% of patients were previously treated with biologic disease-modifying anti-rheumatic drugs (bDMARDs), and 60.4% concomitantly with conventional synthetic DMARDs (csDMARDs). After 6 months, a significant reduction of DAPSA was observed (β − 15.47, p = 0.001, 95% CI − 23.15 to − 9.79) with 39.6% of patients achieving a DAPSA ≤ 14. At the end of cumulative follow-up, 71.2% of patients were still treated with guselkumab whereas 24.3% discontinued the drug because of inefficacy. An 18-month DRR of guselkumab of 66.7% was estimated with a mean time of administration of 9.8 ± 4.1 months. The results of the DRR were stratified according to patient clinical characteristics. The DRR of guselkumab appeared to be not influenced by long disease duration, comorbidities, obesity, concomitant csDMARDs, and previous bDMARDs. Conclusion: The "real-life" 6-month effectiveness of guselkumab was shown in patients with PsA, mainly characterised by active long-standing disease, previously treated with bDMARDs, and with comorbidities. Furthermore, a good DRR of guselkumab was estimated in the cumulative 18 months of follow-up and appeared to be not influenced by long disease duration, comorbidities, obesity, and previous bDMARDs.

OBJECTIVE: To evaluate the four kinds of interleukin biological agents of ustekinumab, ixekizumab, secukinumab and guselkumab, so as to provide scientific basis for drug selection and clinical rational drug use in medical institutions. METHODS: According to the Selection and Evaluation Form of Drug Use (Chemical Drugs) List in the Tertiary Public Medical Institutions in Hebei Province published by Hebei Provincial Health Commission, four kinds of interleukin biological agents were comprehensively evaluated from effectiveness, pharmaceutical characteristics, safety, economy and other properties. RESULTS: The total scores of ustekinumab, ixekizumab, secukinumab and guselkumab were 79. 3, 77. 8, 68. 3 and 76. 3 points respectively. Guselkumab could achieve complete clearing of skin lesions, and the drug retention rate was high. Ustekinumab was the “ dual-targeted ” interleukin-12 and interleukin-23 inhibitor for moderately to severely active Crohn’ s disease in addition to psoriasis. Ixekizumab was a non-whole-human biological preparation, with the highest incidence of adverse reactions among the four types of biological preparations, yet was relatively inexpensive. Sekucizumab and ustekinumab were approved for psoriasis in children and adolescents. CONCLUSIONS: Guselkumab may be considered for patients seeking complete clearance and wishing to maintain better outcomes over time. Ustekinumab may be considered for patients with a history of inflammatory bowel disease or a family history of inflammatory bowel disease. Secukinumab and ustekinumab may be considered for pediatric psoriasis. Ixekizumab may be an option for patients wishing to achieve a rapid onset of action and who have limited ability to pay, yet patients who are susceptible to allergies and at high risk for connective tissue disease should be avoided. Ixekizumab and secukinumab may cause or aggravate inflammatory bowel disease and should be used with caution in clinic. [ABSTRACT FROM AUTHOR]

In this case report, we present a 29-year-old patient with Down syndrome (DS) who manifested both psoriasis and hidradenitis suppurativa (HS) concurrently. The utilization of guselkumab, an interleukin 23 p19 subunit inhibitor that is approved for moderate to severe psoriasis vulgaris, resulted in significant improvement in symptoms for both conditions following the initial administration. The patient achieved a psoriasis area and severity index 90 response with significant amelioration of psoriatic plaques. Simultaneously, more than 50% improvement in abscess and inflammatory nodules secondary to HS was observed 4 weeks after the start of guselkumab therapy, resulting in a HiSCR score achievement. Throughout the 52-week follow-up, there were no observed exacerbations of symptoms or adverse effects. This case highlights the potential benefit of guselkumab in the simultaneous treatment of HS and psoriasis, and suggests that guselkumab is an effective and safe biologic agent of choice in individuals with DS, where the prevalence of both these diseases is increased, and treatment adherence may pose additional challenges compared to the normal population.

For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. Studies regarding infection rates after vaccination are lacking. Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases. [ABSTRACT FROM AUTHOR]

A 52‐week postmarketing surveillance study was initiated to evaluate the safety and effectiveness of guselkumab, a human anti–interleukin 23 subunit p19 monoclonal antibody, in Japanese patients with psoriasis vulgaris, psoriatic arthritis, generalized pustular psoriasis, and erythrodermic psoriasis in real‐world practice. Here, we report results of the 20‐week interim analysis of the ongoing postmarketing surveillance study. Patients who received guselkumab between May 2018 (the date of commercial launch in Japan) and October 2020 were registered in this study. In total, 411 and 245 patients were included in the safety and effectiveness analysis sets, respectively. Adverse drug reactions (ADRs) occurred in 6.6% (27 of 411) and serious ADRs in 2.2% (nine of 411) of patients. The most frequent ADRs by System Organ Class were "Infections and infestations" (2.4%), with nasopharyngitis being the most frequently observed ADR (0.7%). The mean Psoriasis Area Severity Index score decreased from 11.6 at baseline to 6.5 at week 4 and 2.2 at week 20, with improvements achieving statistical significance at each time point. Clinical Global Impression, Dermatology Life Quality Index, and Nail Psoriasis Severity Index outcomesalso showed substantial improvements. Our findings demonstrate that guselkumab is well tolerated and effective in Japanese patients with psoriasis through 20 weeks of treatment in real‐world clinical practice, showing significant effectiveness observed as early as 4 weeks. The study was officially registered with the University Hospital Medical Information Network Clinical Trials Registry with the identifier UMIN000032969. [ABSTRACT FROM AUTHOR]

Mild psoriasis may be burdensome; if symptoms are inadequately controlled, switching therapy may be warranted. In the Phase 3 NAVIGATE trial, patients with moderate-to-severe plaque psoriasis received ustekinumab for 16 weeks. Patients with inadequate response (Investigator’s Global Assessment [IGA] ≥ 2) were randomized to switch to guselkumab or continue ustekinumab. This post-hoc analysis evaluated the patient subgroup with residual mild psoriasis (IGA = 2) after initial ustekinumab therapy. Outcomes assessed included the Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI), and Psoriasis Symptoms and Signs Diary (PSSD). Initially, 871 patients received ustekinumab. At Week 16, 161 randomized patients had residual mild psoriasis (IGA = 2). Among guselkumab- vs ustekinumab-treated patients at Week 28, 59.0% vs 27.7% achieved PASI 90, and 50.0% vs 21.0% achieved DLQI 0/1. Mean changes from baseline in PSSD score were –44 vs –28 and –50 vs –32, respectively, with thresholds of –40 considered clinically meaningful. Mean changes in PSSD itch score were –4.6 vs –2.9, with reductions ≥ 4.0 considered clinically meaningful. Treatment differences were maintained/increased through Week 52. Among patients with residual mild psoriasis after 16 weeks of ustekinumab, those switching to guselkumab had greater improvements in skin clearance, health-related quality of life, and patient-reported symptoms and signs than those continuing ustekinumab.

IL-23 is a cytokine produced by myeloid cells that drives the T helper 17 pathway and plays an essential role in the pathophysiology of plaque psoriasis. IL-23 activation initiates a cascade of cytokines subsequently inducing the expression of many psoriasis-related proteins. This study aimed to better understand the underlying mechanisms driving the differences between IL-23 and IL-17A blockade in patients with psoriasis and their implications for durability of clinical responses. Serum and/or skin biopsies were isolated from patients treated with guselkumab or secukinumab for evaluation of potential biomarkers of pharmacodynamic response to treatment. Guselkumab treatment led to significantly greater reductions of IL-17F and IL-22 serum levels than treatment with secukinumab at weeks 24 and 48, demonstrating sustained regulation of the IL-23/T helper 17 pathway. Analyses of proteomic and transcriptomic profiles of patient sera and skin biopsies demonstrated differential regulation of proteins involved in chemokine, TNF, and relevant immune signaling pathways to a greater degree with guselkumab than with secukinumab treatment. These data provide insights into the differences between the mechanisms and impact of IL-23 and IL-17A blockade in psoriasis, with implications for efficacy observations and treatment paradigms. Trial Registration: The original study was registered at ClinicalTrials.gov (NCT03090100).

Background: Psoriasis is an immune-mediated inflammatory disease characterized by activation of IL-23–driven IL-17–producing T cell and other IL-23 receptor–positive IL-17–producing cell responses. Selective blockade of IL-23p19 with guselkumab was superior to blockade of TNF-α with adalimumab (ADA) in treating moderate-to-severe psoriasis. Objective: Pharmacodynamic responses of guselkumab versus ADA were compared in patients with psoriasis in VOYAGE 1. Design: Inflammatory cytokine serum levels were assessed (n = 118), and lesional and nonlesional skin biopsies were collected (n = 38) in patient subsets at baseline and 4, 24, and 48 weeks after treatment to evaluate pharmacodynamic responses of guselkumab versus those of ADA. Results: Guselkumab provided rapid reductions in serum IL-17A, IL-17F, and IL-22 levels by week 4 versus at baseline, which were maintained through weeks 24 and 48 (P < .001). The magnitude of reduction of IL-17A and IL-22 at week 48 and IL-17F at weeks 4, 24, and 48 were greater with guselkumab than with ADA (all P < .05). In the skin, guselkumab reduced the expression of IL-23/IL-17 pathway–associated and psoriasis-associated genes. Conclusion: These data provide extensive characterization of pharmacodynamic anti-inflammatory responses to IL-23p19 and TNF-α inhibition in human blood and tissue over time with FDA-approved doses of guselkumab and ADA. Trial registration: ClinicalTrials.govClinicalTrials.gov (NCT02207231).

IntroductionEmerging evidence suggests psoriatic arthritis (PsA) with axial involvement (axPsA) and radiographic axial spondyloarthritis (r-axSpA) may possibly represent distinct disorders, with some differing clinical manifestations, genetic associations, and radiographic findings. Moreover, axPsA and r-axSpA may respond differently to therapies: guselkumab (interleukin [IL]-23p19 subunit inhibitor [i]) and ustekinumab (IL-12/23p40i) demonstrated improvements in axial symptoms in patients with PsA; however, neither risankizumab (IL-23p19i) nor ustekinumab demonstrated efficacy versus placebo in patients with r-axSpA. Current analyses aim to further understand potential molecular distinctions between axPsA and r-axSpA and examine the pharmacodynamic effects of guselkumab in patients with axPsA and those with PsA without axial involvement (non-axPsA).MethodsPost hoc analyses utilized biomarker data from blood and serum samples collected from a subset of participants in phase 3 studies of ustekinumab in r-axSpA and guselkumab in PsA (DISCOVER-1 and DISCOVER-2). Participants with axPsA were identified by investigator-verified sacroiliitis (imaging-confirmed) and axial symptoms. HLA mapping, serum cytokine analysis, and whole-blood RNA sequencing were conducted.ResultsRelative to r-axSpA, patients with axPsA had a lower prevalence of HLA-B27, HLA-C01, and HLA-C02 alleles and a higher prevalence of HLA-B13, HLA-B38, HLA-B57, HLA-C06, and HLA-C12 alleles. Compared with r-axSpA, patients with axPsA had elevated baseline levels of serum IL-17A and IL-17F cytokines, enrichment of IL-17 and IL-10 pathway-associated genes, and neutrophil gene markers. Across axPsA and non-axPsA cohorts, reductions in cytokine levels and normalization of pathway-associated gene expression with guselkumab treatment were comparable.ConclusionThe differences in HLA genetic associations, serum cytokines, and enrichment scores support the concept that axPsA and r-axSpA may be distinct disorders. The comparable pharmacodynamic effects of guselkumab on cytokine levels and pathway-associated genes observed in patients with axPsA and non-axPsA are consistent with demonstrated clinical improvements across PsA cohorts. These findings contribute to the understanding of potential genetic and molecular distinctions between axPsA and r-axSpA.Trial registrationClinicalTrials.gov identifiers, NCT03162796, NCT0315828, NCT02437162, and NCT02438787.

Abstract Background Tumor necrosis factor inhibitors (TNFi) are frequently chosen as the first biologic for patients with psoriatic arthritis (PsA). Given that many patients with PsA are TNFi inadequate responders (TNF-IR; either inadequate efficacy or intolerance), treatments utilizing alternative mechanisms of action are needed. In phase 3 studies, the fully human interleukin (IL)-23p19 subunit-inhibitor, guselkumab, was efficacious in patients with active PsA, including TNFi-IR. Efficacy was generally consistent between TNFi-naïve and TNFi-experienced cohorts; however, in the latter, higher response rates have been observed with the Q4W dosing regimen relative to the Q8W dosing regimen for some endpoints, suggesting the need to evaluate whether more frequent dosing may provide an incremental clinical benefit for TNFi-IR patients. Methods The phase 3b SOLSTICE study will assess guselkumab efficacy and safety in TNFi-IR PsA patients. Eligibility criteria include a PsA diagnosis for ≥ 6 months; active disease (≥ 3 swollen, ≥ 3 tender joints, C-reactive protein ≥ 0.3 mg/dL); and inadequate efficacy with, and/or intolerance to, one prior TNFi. Participants will be randomized 1:1:1 to guselkumab Q4W or Q8W or placebo→guselkumab Q4W (at Week 24). The primary endpoint is the proportion of patients achieving ≥ 20% improvement in the American College of Rheumatology criteria (ACR20) at Week 24. Major secondary endpoints include ACR50, ACR70; an Investigator’s Global Assessment (IGA) of psoriasis score of 0/1 plus ≥ 2-grade reduction and ≥ 90% improvement in Psoriasis Area and Severity Index (both among patients with ≥ 3% body surface area affected by psoriasis and baseline IGA ≥ 2); minimal/very low disease activity; and changes from baseline in Health Assessment Questionnaire-Disability Index, the 36-item Short-Form Health Survey Physical Component Summary, and Functional Assessment of Chronic Illness Therapy-Fatigue scores. The target sample size (N = 450) is estimated to provide > 90% power in detecting differences between each guselkumab group and the placebo group for the primary endpoint assuming a 2-sided α = 0.05. Cochran-Mantel–Haenszel testing and analyses of covariance will be used to compare efficacy for binary and continuous endpoints, respectively. Discussion Findings from the phase 3b SOLSTICE study, the design of which was informed by results from previously conducted phase 3 studies, is expected to provide important efficacy and safety information on guselkumab therapy in TNFi-IR patients with PsA. Trial registration This trial was registered at ClinicalTrials.gov, NCT04936308, on 23 June 2021.

Objective To observe the clinical efficacy and safety of guselkumab injection in the treatment of moderate to severe plaque psoriasis. Methods Twenty three patients with moderate to severe plaque psoriasis were treated with subcutaneous injection of guselkumab at a dose of 100 mg at weeks 0 and 4, followed by once every 8 weeks. The psoriasis lesion area and severity index (PASI) were evaluated at weeks 4 and 12, and adverse reactions were recorded. Results All 23 patients received treatment at least 3 times (0, 4, 12 weeks). At week 12, 23 patients (100%) achieved PASI 75 or above, including PASI 90 in 19 patients (82.61%) and PASI 100 in 10 patients (43.48%). No serious adverse reactions were observed. Conclusions Guselkumab is safe and effective for moderate to severe plaque psoriasis, and can rapidly improve skin lesions. It provides a new treatment option for patients with moderate to severe plaque psoriasis.

Abstract Introduction Guselkumab is an interleukin-23 (IL-23) inhibitor licensed for the treatment of psoriatic arthritis (PsA). This study aimed to evaluate the 6-month effectiveness of guselkumab in patients with PsA in a “real-life” multicentre patient cohort. We also estimated the drug retention rate (DRR) of gusulkumab, also assessing the impact of comorbidities and patient clinical characteristics, in a collective 18-month prospective follow-up. Methods Between December 2021 and September 2023, consecutive patients with PsA were evaluated if treated at least for 6 months with guselkumab in a prospective multicentre study to evaluate the effectiveness of the drug by means of disease activity index for psoriatic arthritis (DAPSA) and cumulative DRR. Results A total of 111 patients with PsA were evaluated and treated with guselkumab (age 56.8 ± 9.9, male sex 20.7%). These patients were mainly characterised by active and long-standing PsA with median disease duration of 6.0 (7.0) years (55.9% disease duration ≥ 5 years), 55.0% showed comorbidities, 78.4% of patients were previously treated with biologic disease-modifying anti-rheumatic drugs (bDMARDs), and 60.4% concomitantly with conventional synthetic DMARDs (csDMARDs). After 6 months, a significant reduction of DAPSA was observed (β − 15.47, p = 0.001, 95% CI − 23.15 to − 9.79) with 39.6% of patients achieving a DAPSA ≤ 14. At the end of cumulative follow-up, 71.2% of patients were still treated with guselkumab whereas 24.3% discontinued the drug because of inefficacy. An 18-month DRR of guselkumab of 66.7% was estimated with a mean time of administration of 9.8 ± 4.1 months. The results of the DRR were stratified according to patient clinical characteristics. The DRR of guselkumab appeared to be not influenced by long disease duration, comorbidities, obesity, concomitant csDMARDs, and previous bDMARDs. Conclusion The “real-life” 6-month effectiveness of guselkumab was shown in patients with PsA, mainly characterised by active long-standing disease, previously treated with bDMARDs, and with comorbidities. Furthermore, a good DRR of guselkumab was estimated in the cumulative 18 months of follow-up and appeared to be not influenced by long disease duration, comorbidities, obesity, and previous bDMARDs.

Abstract Introduction Matching-adjusted indirect comparisons (MAIC) were used to assess the relative efficacy of bimekizumab 160 mg every 4 weeks (Q4W) compared to guselkumab 100 mg Q4W or every 8 weeks (Q8W) at 48/52 weeks in patients with psoriatic arthritis (PsA) who were biologic disease-modifying antirheumatic drug-naïve (bDMARD-naïve) or with previous inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR). Methods Relevant trials were identified as part of a systematic literature review. For patients who were bDMARD-naïve, individual patient data (IPD) from BE OPTIMAL (N = 431) was matched to summary data from DISCOVER-2 (Q4W, n = 245; Q8W, n = 248). For patients who were TNFi-IR, IPD from BE COMPLETE (n = 267) and summary data from COSMOS (Q8W, N = 189). Trial populations were re-weighted using propensity scores. Unanchored comparisons of recalculated bimekizumab and guselkumab 48- or 52-week non-responder imputation outcomes for 20/50/70% improvement in American College of Rheumatology score (ACR20/50/70) and minimal disease activity (MDA) index were analyzed. Results In patients who were bDMARD-naïve, bimekizumab was associated with a greater likelihood of ACR50 (odds ratio [95% confidence interval] 1.62 [1.07, 2.44]; p = 0.021), ACR70 (2.20 [1.43, 3.38]; p

Abstract Introduction This study aimed to understand treatment response dynamics, including factors associated with favorable response, among patients with moderate-to-severe psoriasis who received guselkumab, adalimumab, or secukinumab. Methods These post hoc analyses used data from the phase III clinical trials ECLIPSE and VOYAGE 1, which were conducted between September 2021 and November 2022. On the basis of absolute Psoriasis Area and Severity Index (aPASI) scores, patients were divided into short-term response types (SRT1–6, based on week 20–48 response) and long-term response types (LRT1–4, based on week 52–252 response). Response types (RTs) were based on aPASI cutoffs deemed clinically relevant by the investigators; SRT1/LRT1 were the most favorable response types. Baseline characteristics were compared across RTs, and logistic regression analyses established factors associated with SRT1/LRT1. Results Overall, 1045, 662, and 272 patients were included in the ECLIPSE short-term, VOYAGE 1 short-term, and VOYAGE 1 long-term analyses, respectively. Mean age, body mass index (BMI), baseline aPASI score, and body surface area were lower in SRT1 than SRT6. In VOYAGE 1, adalimumab treatment, high BMI, and current/former smoking status resulted in less favorable responses. In the VOYAGE 1 long-term analysis, patients in LRT4 had the highest baseline aPASI score, were older, and were more often obese compared with other LRT groups. Regression analyses showed that SRT1 (both treatments) in VOYAGE 1 and ECLIPSE, and LRT1 (guselkumab group) in the VOYAGE 1 long-term analysis, were associated with week 16 aPASI response. In VOYAGE 1, SRT1 was associated with psoriasis duration and smoking status. Conclusions Early treatment response and baseline characteristics, including smoking, psoriasis duration, and obesity, may be associated with longer-term response to biologics. Trial Registration Numbers ECLIPSE: NCT03090100, VOYAGE 1: NCT02207231.

Background Biologics are essential in treating psoriasis. In recent years, the pathogenesis exploration and development of new target drugs have provided a more complete evidence-based foundation for the biological treatment of psoriasis. This study aims to use bibliometrics to analyze the research status and development trends of biologics in psoriasis.Methods The bibliometric analysis of publications related to biologics in psoriasis from 2004 to 2023 was conducted using the Web of Science Core Collection (WoSCC) database as the search data source. To perform the bibliometric analysis and create visual knowledge graphs, CiteSpace, the Bibliometrix R package, and VOSviewers were utilized.Results The study included a total of 3800 articles. The United States had the highest number of publications. The leading authors and institutions were Steven R. Feldman and the University of Manchester, respectively, in the global partnership. The cluster plot divided all keywords into 11 categories. Currently, Secukinumab and Guselkumab are representative biological agents being studied due to their considerable efficacy and long-term safety.Conclusions Targeted therapy has emerged as a significant trend in the current treatment of psoriasis. Early and active use of biologics can effectively control disease progression, prevent or delay the occurrence of comorbidities, and may even alter the natural course of psoriasis. However, further investigation is required to fully understand the specific mechanisms of psoriasis and the use of biological agents.

AbstractPurpose: Real-world data comparing long-term performance of interleukin (IL)-23 and IL-17 inhibitors in psoriasis are limited. This study compared treatment persistence and remission among patients initiating guselkumab versus IL-17 inhibitors.Methods: Adults with psoriasis initiating guselkumab, secukinumab, or ixekizumab treatment (index date) were identified from Merative™ MarketScan® Research Databases (01/01/2016–10/31/2021). Persistence was defined as no index biologic supply gaps of twice the labeled maintenance dosing interval. Remission was defined using an exploratory approach as index biologic discontinuation for ≥6 months without psoriasis-related inpatient admissions and treatments.Results: There were 3516 and 6066 patients in the guselkumab versus secukinumab comparison, and 3805 and 4674 patients in guselkumab versus ixekizumab comparison. At 18 months, the guselkumab cohort demonstrated about twice the persistence rate as secukinumab (hazard ratio [HR] = 2.15; p < 0.001) and ixekizumab cohorts (HR = 1.77; p < 0.001). At 6 months after index biologic discontinuation, the guselkumab cohort was 31% and 40% more likely to achieve remission than secukinumab (rate ratio [RR] = 1.31; p < 0.001) and ixekizumab cohorts (RR = 1.40; p < 0.001).Conclusions: Guselkumab was associated with greater persistence and likelihood of remission than IL-17 inhibitors, indicating greater disease control and modification potential.

AbstractThe purpose of the article: Generalized pustular psoriasis (GPP) is a rare auto-inflammatory disease. Patients with GPP may develop life-threatening complications, including sepsis, acute renal failure, neutrophilic cholangitis, high-output congestive heart failure, acute respiratory distress syndrome and death. The therapy of GPP is very limited and the course of the disease is unpredictable.Materials and methods: We report a 60-year-old woman presenting with widespread and confluent erythematous-desquamative plaques with numerous small pustules covering almost 70% of the body surface area. Over the past years patient had undergone different types of conservative treatment regimens including topical therapy, acitretin, cyclosporin, methotrexate and long-term treatment with systemic corticosteroids. Considering the patient’s overall clinical condition, we proceed to initiate the biologic therapy with guselkumab.Results: Guselkumab (anti-IL-23) in the standard dose of 100 mg was administered subcutaneously at weeks 0, 4 and followed by a maintenance dose every 8 weeks. The remission of GPP was observed already after 12 weeks of treatment. The maintenance treatment in the period of 18 months shows stable clinical response.Conclusions: Our results support the evidence that guselkumab could provide an effective therapeutic approach in the treatment of GPP.

Guselkumab is the first approved human IgG1λ monoclonal antibody selectively targeting the p19 subunit of interleukin (IL)-23. Despite its effectiveness and safety, which have been widely reported by clinical trials and real-life experiences, data regarding its use on patients who previously failed anti-IL17 are limited or characterized by a reduced follow-up period. These data are essential to guide clinicians in biologic switching, considering that anti-IL23 and anti-IL17 partially share their therapeutic targets, as well as some patients who may have to interrupt treatment with anti-IL17 for loss of efficacy over time or the development of adverse events (AEs). In this context, we performed a retrospective study with the aim of evaluating the long-term use (2 years) of guselkumab in psoriasis patients who previously failed at least one anti-IL17 in a real-life setting, also focusing attention on psoriasis located in difficult-to-treat areas (the scalp, palms or soles, fingernails, genitals). A total of 61 patients (35 male, 57.4%; mean age 57.6 ± 8.8 years) were enrolled. Of these, 30 (49.2%) patients failed secukinumab, 21 (34.4%) failed ixekizumab, 7 (11.5%) failed brodalumab, and 3 (4.9%) failed both secukinumab and ixekizumab. At the baseline, the mean PASI and BSA were 12.8 ± 8.4 and 24.5 ± 26.6, respectively. During week 16, PASI90 and PASI100 responses were achieved by 60.7% and 37.7% of patients, respectively, which continued to improve up to week 104 (PASI90: 73.8%, PASI100: 59.0%). Clinical improvement in difficult-to-treat areas was detected as well. In particular, a slower improvement for fingernails and the palmoplantar region was reported compared to scalp and genital psoriasis at week 16. However, no differences were found following 28 weeks of therapy. Primary and secondary inefficacy were reported by 1 (1.6%) and 5 (8.2%) patients. As regards safety, no severe AEs were collected.

Background: Guselkumab is the first approved human IgG1λ monoclonal antibody selectively targeting the p19 subunit of IL23. Its effectiveness and safety were widely reported by clinical trials. However, these results must be confirmed in real life since its safety deals with more complicated subjects with respect to trials. Currently, real-life data on the use of guselkumab following treatment failure with ustekinumab are limited, and existing studies usually show a small cohort and/or a reduced follow-up period. In this context, the aim of our study was to evaluate the use of guselkumab in patients who previously did not respond to ustekinumab after up to 3 years of treatment. Methods: A multicenter retrospective study was performed. The study enrolled patients affected by moderate-to-severe plaque psoriasis undergoing treatment with guselkumab who were attending the Psoriasis Center of nine different centers in the Campania region of Italy. Demographic and clinical features were collected for each patient at baseline. Moreover, data on psoriasis severity and adverse events (AEs) were collected at each follow-up visit (week (W)16-W36-W52-W104-W156). Results: A total of 112 patients (70 male, 62.5%; mean age 54.8 ± 11.7 years old) were enrolled. Of these, 48 (42.9%), 34 (30.4%), and 16 (14.3%) reached 1, 2, and 3 years, respectively, of follow-up under guselkumab. A statistically significant clinical improvement was observed since W16, and sustained effectiveness was reported at each timepoint up to W156. No serious AEs were collected. Moreover, a sub analysis on the body mass index, involvement of difficult-to-treat areas, and presence of psoriatic arthritis (PsA) showed that the presence of PsA or palmoplantar psoriasis was associated with a reduced clinical improvement at W16 and W36, without differences from W52. In contrast, the efficacy of guselkumab does not seem to be affected by the BMI, involvement of fingernails, or location in the genital or scalp area. Conclusions: To sum up, our long-term real-life multicenter retrospective study confirmed the efficacy and safety of guselkumab following ustekinumab discontinuation up to 156 weeks of treatment.

Le rhumatisme psoriasique axial a de nombreuses caractéristiques en commun avec la spondyloarthrite axiale, mais il s'en distingue par certains aspects qui lui sont spécifiques. Il présente notamment des différences radiographiques et cliniques par rapport à la spondyloarthrite axiale. L'imagerie montre généralement des syndesmophytes asymétriques touchant essentiellement le rachis cervical, ainsi que, moins fréquemment, une sacro-iliite. Le rhumatisme psoriasique axial se manifeste à un âge plus avancé et est associé à une rachialgie inflammatoire moins sévère que dans le cas de la spondyloarthrite axiale. L'axe interleukine-23/interleukine-17 est au cœur de la pathogenèse des deux maladies, mais des thérapies ciblant ces cytokines ont obtenu des réponses différentes. Les inhibiteurs de l'interleukine-23, qui ne sont pas efficaces dans la spondyloarthrite axiale, pourraient l'être dans le rhumatisme psoriasique. Des analyses post hoc de résultats d'essais cliniques menés sur les inhibiteurs de l'interleukine-23 dans le rhumatisme psoriasique ont récemment suggéré une efficacité possible dans le rhumatisme psoriasique axial et de nouvelles études devraient être conduites pour évaluer cette hypothèse. Par ailleurs, des critères de classification du rhumatisme psoriasique axial et des outils plus adaptés pour évaluer la réponse thérapeutique sont nécessaires. Axial psoriatic arthritis (axPsA) has considerable overlap with axial spondyloarthritis (axSpA) but has some unique features that sometimes preclude classification into axSpA. It has some clinical and radiographic differences compared to axSpA. Imaging typically shows asymmetric syndesmophytes, mainly in the cervical spine, with less frequent sacroiliitis. It more commonly presents later in life and is associated with less severe inflammatory back pain than axSpA. The interleukin (IL) IL-23/IL-17 axis is central to the pathogenesis of both diseases. However, the response to therapies targeting these cytokines has been different. IL-23 inhibitors are ineffective in axSpA but may be effective in psoriatic arthritis (PsA). Recent post hoc analyses of clinical trial data with IL-23 inhibitors in PsA have raised the possibility of their efficacy in axPsA and need evaluation in future clinical trials. Moreover, there is a need for classification criteria for axPsA and better tools to assess therapeutic response. [ABSTRACT FROM AUTHOR]

Introduction: To evaluate the effect of guselkumab on work productivity and nonwork daily activity impairment and general health status through 2 years in patients who were biologic-naïve with active psoriatic arthritis (PsA) in the phase 3 DISCOVER-2 clinical trial. Methods: Adult patients with PsA were randomized to subcutaneous injections of guselkumab 100 mg every 4 weeks (Q4W); at weeks 0, 4, then every 8 weeks (Q8W); or placebo (through week 24 with crossover to guselkumab Q4W). Work productivity and nonwork daily activity impairment were assessed using the Work Productivity and Activity Impairment Questionnaire for PsA (WPAI-PsA) and patient-reported general health status using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) Index and EQ-Visual Analog Scale (EQ-VAS). Least-squares (LS) mean changes from baseline in WPAI-PsA domains and EQ-5D-5L/EQ-VAS were assessed through week 100. Changes in employment status were utilized to estimate potential indirect savings from improved work productivity. Results: Of 739 randomized patients, 738 had available baseline data for the analyses (Q4W 245; Q8W 248; placebo 245). At week 24, greater improvements in work productivity, nonwork daily activity, and EQ-5D-5L/EQ-VAS were observed in the Q4W and Q8W groups versus the placebo group. At week 100, LS mean reductions in work productivity impairment (− 23.8% to − 28.0%) and nonwork daily activity impairment (– 26.6% to − 29.2%) and improvements in EQ-5D-5L/EQ-VAS (0.14 to 0.15/21.2 to 25.0) were maintained in patients receiving guselkumab. Among patients employed at baseline, 12.1–16.4% were not employed at week 100, and 20.0–25.3% shifted from not employed at baseline to employed at week 100. Potential yearly indirect cost savings (USD) from improved work productivity at week 100 ranged from $16,529 to $19,409. Conclusion: Patients with active PsA treated with guselkumab demonstrated reduced impairment in work productivity and nonwork daily activity, together with improvement in general health status and substantial potential cost savings, over a 2-year period.

Introduction: Two biologic therapies for psoriatic arthritis (PsA), guselkumab and ustekinumab, have demonstrated superior efficacy versus placebo in clinical trials. However, no head-to-head studies have been conducted comparing these two treatments for PsA. The objective was to indirectly compare guselkumab and ustekinumab on joint and skin efficacy up to week 52, using pooled individual patient-level data (IPD) from PsA trials. Methods: IPD, including baseline characteristics, American College of Rheumatology (ACR) scores and Psoriasis Area Severity Index (PASI) response from guselkumab (DISCOVER-1 and -2) and ustekinumab (PSUMMIT 1 and 2) trials were pooled. Differences in patient characteristics across trials were adjusted using multivariate logistic regression. Odds ratios (OR) were used to derive absolute response probabilities in the guselkumab trial population and were presented with 95% confidence intervals. Results: Most baseline characteristics for guselkumab-treated patients (100 mg every 8 weeks [Q8W]; 100 mg every 4 weeks [Q4W]) were comparable to ustekinumab-treated patients (45/90 mg). In biologic-naïve patients, both guselkumab doses showed significantly higher ACR 20 (Q8W: 1.97; 1.37, 2.84; Q4W: 2.04; 1.40, 2.96) and PASI 90 (Q8W: 2.33; 1.52, 3.56; Q4W: 2.57; 1.67, 3.97) versus ustekinumab from week 16 onwards. In biologic-experienced patients, both guselkumab doses showed significantly higher ACR 20 (Q8W: 2.57; 1.11, 5.93; Q4W: 2.63; 1.12, 6.17) versus ustekinumab from week 24 onwards; for PASI 90, both guselkumab doses were superior to ustekinumab at week 16 and 52 (Q8W: 3.96; 1.39, 11.27; Q4W: 13.10; 4.18, 41.04). Guselkumab efficacy was similar and robust across primary, scenario, and sensitivity analyses. Conclusions: IPD analysis demonstrated that both guselkumab doses were superior to ustekinumab for ACR 20 from weeks 16 (biologic-naïve) and 24 (biologic-experienced) onwards, and for PASI 90 at weeks 16 and 52 for both subgroups.

Introduction: This study aimed to understand treatment response dynamics, including factors associated with favorable response, among patients with moderate-to-severe psoriasis who received guselkumab, adalimumab, or secukinumab. Methods: These post hoc analyses used data from the phase III clinical trials ECLIPSE and VOYAGE 1, which were conducted between September 2021 and November 2022. On the basis of absolute Psoriasis Area and Severity Index (aPASI) scores, patients were divided into short-term response types (SRT1–6, based on week 20–48 response) and long-term response types (LRT1–4, based on week 52–252 response). Response types (RTs) were based on aPASI cutoffs deemed clinically relevant by the investigators; SRT1/LRT1 were the most favorable response types. Baseline characteristics were compared across RTs, and logistic regression analyses established factors associated with SRT1/LRT1. Results: Overall, 1045, 662, and 272 patients were included in the ECLIPSE short-term, VOYAGE 1 short-term, and VOYAGE 1 long-term analyses, respectively. Mean age, body mass index (BMI), baseline aPASI score, and body surface area were lower in SRT1 than SRT6. In VOYAGE 1, adalimumab treatment, high BMI, and current/former smoking status resulted in less favorable responses. In the VOYAGE 1 long-term analysis, patients in LRT4 had the highest baseline aPASI score, were older, and were more often obese compared with other LRT groups. Regression analyses showed that SRT1 (both treatments) in VOYAGE 1 and ECLIPSE, and LRT1 (guselkumab group) in the VOYAGE 1 long-term analysis, were associated with week 16 aPASI response. In VOYAGE 1, SRT1 was associated with psoriasis duration and smoking status. Conclusions: Early treatment response and baseline characteristics, including smoking, psoriasis duration, and obesity, may be associated with longer-term response to biologics. Trial Registration Numbers: ECLIPSE: NCT03090100, VOYAGE 1: NCT02207231. [ABSTRACT FROM AUTHOR]

Introduction: Guselkumab is an interleukin 23p19 inhibitor, and the first in this group, to be approved by the US Food and Drug Administration (FDA) for the management of moderate to severe psoriasis. Apart from its utility in psoriasis, there are a number of other dermatologic conditions where guselkumab has demonstrated value. Objectives: The aim of this narrative review is to describe the utility of guselkumab in psoriasis as well as its implication in off-label dermatologic disorders. Methods: Pubmed, Google Scholar, Scopus and ResearchGate were searched for scholarly articles related to guselkumab and its utility in dermatology using the search terms “Guselkumab” AND “Psoriasis” AND “other dermatological disorders”. Results: Guselkumab is a valuable biologic agent for the management of psoriasis and psoriatic arthropathy. It has also been used successfully for other dermatologic disorders like hidradenitis suppurativa, lichen planus, pityriasis rubra pilaris and pyoderma gangrenosum. Recently, its utility in Stewart-Treves angiosarcoma (STA) has been exemplified. Conclusion: Guselkumab’s usage is not limited to psoriasis. Its benefit extends to many more dermatologic conditions. Its utility in STA could open an avenue for its application in the field of oncology. Furthermore, it has an acceptable safety profile.

Results Most baseline characteristics for guselkumab-treated patients (100 mg every 8 weeks [Q8W]; 100 mg every 4 weeks [Q4W]) were comparable to ustekinumab-treated patients (45/90 mg). In biologic-naïve patients, both guselkumab doses showed significantly higher ACR 20 (Q8W: 1.97; 1.37, 2.84; Q4W: 2.04; 1.40, 2.96) and PASI 90 (Q8W: 2.33; 1.52, 3.56; Q4W: 2.57; 1.67, 3.97) versus ustekinumab from week 16 onwards. In biologic-experienced patients, both guselkumab doses showed significantly higher ACR 20 (Q8W: 2.57; 1.11, 5.93; Q4W: 2.63; 1.12, 6.17) versus ustekinumab from week 24 onwards; for PASI 90, both guselkumab doses were superior to ustekinumab at week 16 and 52 (Q8W: 3.96; 1.39, 11.27; Q4W: 13.10; 4.18, 41.04). Guselkumab efficacy was similar and robust across primary, scenario, and sensitivity analyses. Conclusions IPD analysis demonstrated that both guselkumab doses were superior to ustekinumab for ACR 20 from weeks 16 (biologic-naïve) and 24 (biologic-experienced) onwards, and for PASI 90 at weeks 16 and 52 for both subgroups.

Abstract Introduction To evaluate the effect of guselkumab on work productivity and nonwork daily activity impairment and general health status through 2 years in patients who were biologic-naïve with active psoriatic arthritis (PsA) in the phase 3 DISCOVER-2 clinical trial. Methods Adult patients with PsA were randomized to subcutaneous injections of guselkumab 100 mg every 4 weeks (Q4W); at weeks 0, 4, then every 8 weeks (Q8W); or placebo (through week 24 with crossover to guselkumab Q4W). Work productivity and nonwork daily activity impairment were assessed using the Work Productivity and Activity Impairment Questionnaire for PsA (WPAI-PsA) and patient-reported general health status using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) Index and EQ-Visual Analog Scale (EQ-VAS). Least-squares (LS) mean changes from baseline in WPAI-PsA domains and EQ-5D-5L/EQ-VAS were assessed through week 100. Changes in employment status were utilized to estimate potential indirect savings from improved work productivity. Results Of 739 randomized patients, 738 had available baseline data for the analyses (Q4W 245; Q8W 248; placebo 245). At week 24, greater improvements in work productivity, nonwork daily activity, and EQ-5D-5L/EQ-VAS were observed in the Q4W and Q8W groups versus the placebo group. At week 100, LS mean reductions in work productivity impairment (− 23.8% to − 28.0%) and nonwork daily activity impairment (– 26.6% to − 29.2%) and improvements in EQ-5D-5L/EQ-VAS (0.14 to 0.15/21.2 to 25.0) were maintained in patients receiving guselkumab. Among patients employed at baseline, 12.1–16.4% were not employed at week 100, and 20.0–25.3% shifted from not employed at baseline to employed at week 100. Potential yearly indirect cost savings (USD) from improved work productivity at week 100 ranged from $16,529 to $19,409. Conclusion Patients with active PsA treated with guselkumab demonstrated reduced impairment in work productivity and nonwork daily activity, together with improvement in general health status and substantial potential cost savings, over a 2-year period.

Abstract Introduction Despite improved treatment options for plaque psoriasis within the last decades, some patients still have an inadequate response to treatment. Direct clinical evaluation between therapies used after biologic failure could facilitate physicians’ choice of treatment. Methods COBRA (NCT04533737) was a randomized (1:1), blinded (patient and assessor), 28-week, active-comparator trial conducted in Europe from December 2020 to December 2022. The objective was to compare the efficacy and safety of brodalumab versus guselkumab in adults with moderate-to-severe plaque psoriasis and inadequate response to ustekinumab. Patients received either brodalumab 210 mg or guselkumab 100 mg. The primary [having Psoriasis Area and Severity Index (PASI)-100 response at week 16] and key secondary (time to PASI-100 response) endpoints were tested in a fixed sequence. Results Due to delays and enrollment challenges, recruitment was terminated with 113 patients enrolled of 240 planned. The proportion of patients having PASI-100 at week 16 for brodalumab was 53.4% compared with 35.9% for guselkumab [odds ratio (OR) 2.05; 95% confidence interval (CI) 0.95, 4.44; p = 0.069]. As this was not statistically significant, the hierarchical testing procedure was stopped. All other secondary PASI endpoints had nominal p-values below 0.05 in favor of brodalumab. In the time to PASI response analyses, brodalumab separated from guselkumab in estimated cumulative incidence of patients achieving a response from week 2 onward, suggesting fast onset of action with brodalumab. Quality of life measures improved in both treatment groups. The safety findings were consistent with the known safety profiles. Conclusions Brodalumab showed a tendency toward better and earlier effect than guselkumab in patients who had failed ustekinumab. Thus, this trial provides important information in assisting physicians in their choice of therapy for patients who have failed their prior anti-interleukin (IL)-12/23 treatment.
