Five-year maintenance of clinical response and health-related quality of life improvements in patients with moderate-to-severe psoriasis treated with guselkumab: results from VOYAGE 1 and VOYAGE 2

Bibliometric analysis and description of research trends in the treatment of psoriasis with biologic agents in the past two decades (2004-2023)

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.

Durable control of psoriatic arthritis with guselkumab across domains and patient characteristics: post hoc analysis of a phase 3 study

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.

IL-23 past, present, and future: a roadmap to advancing IL-23 science and therapy

Interleukin (IL)-23, an IL-12 cytokine family member, is a hierarchically dominant regulatory cytokine in a cluster of immune-mediated inflammatory diseases (IMIDs), including psoriasis, psoriatic arthritis, and inflammatory bowel disease. We review IL-23 biology, IL-23 signaling in IMIDs, and the effect of IL-23 inhibition in treating these diseases. We propose studies to advance IL-23 biology and unravel differences in response to anti-IL-23 therapy. Experimental evidence generated from these investigations could establish a novel molecular ontology centered around IL-23-driven diseases, improve upon current approaches to treating IMIDs with IL-23 inhibition, and ultimately facilitate optimal identification of patients and, thereby, outcomes.

The Role of Interleukin 23/17 Axis in Psoriasis Management: A Comprehensive Review of Clinical Trials

Psoriasis pathogenesis is influenced by genetic factors and characterized by a complex interplay between genetic predisposition and various environmental triggers. These triggers set off metabolic processes involving inflammation, cell signaling, immune response dysregulation, and antigen presentation. Several types of innate and adaptive immune cells are involved in psoriasis. Among the cytokine cascade which leads to psoriasis development, the interleukin (IL)-23/Th17 axis, especially IL-17 production, emerges as crucial. Recognizing the pivotal role of this axis has facilitated the development of selective and effective biological drugs, such as anti-IL17 and anti-IL23 monoclonal antibodies. These drugs aim to achieve the complete or near-complete disappearance of psoriatic lesions, as indicated by PASI100 and PASI90 responses, respectively. In this context, the aim of our review was to delve into the functioning of the IL-23/Th17 axis, its dysregulation in psoriasis pathogenesis, and the therapeutic potential of its inhibition. Currently, 4 anti-IL17 (secukinumab, ixekizumab, bimekizumab and brodalumab) and 3 anti-IL23 (guselkumab, risankizumab and tildrakizumab) have been approved. All these drugs showed high levels of effectiveness in both clinical trials and real-life experiences, with an excellent profile in terms of safety. Certainly, furthers studies will allow for better characterization of biologics' profile, in order to administer the right drug for the right patients at the right moment.

Guselkumab provides durable improvement across psoriatic arthritis disease domains: post hoc analysis of a phase 3, randomised, double-blind, placebo-controlled study

OBJECTIVE

Evaluate long-term guselkumab effectiveness across Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-recognised domains/related conditions of psoriatic arthritis (PsA).

METHODS

Post hoc analyses used data from DISCOVER-2 (NCT03158285) biologic/Janus-kinase inhibitor-naïve participants with active PsA (≥5 swollen/≥5 tender joints, C-reactive protein ≥0.6 mg/dL), randomised (1:1:1) to guselkumab every 4 or 8 weeks (Q4W/Q8W) or placebo with crossover to guselkumab. Outcomes aligned with key GRAPPA-recognised domains of overall disease activity, peripheral arthritis, axial disease, enthesitis/dactylitis and skin psoriasis (nail psoriasis was not evaluated). PsA-related conditions (inflammatory bowel disease (IBD)/uveitis) were assessed via adverse events through W112. Least squares mean changes from baseline through W100 in continuous outcomes employed repeated measures mixed-effects models adjusting for baseline scores. Binary measure response rates were determined with non-responder imputation for missing data.

RESULTS

442/493 (90%) of guselkumab-randomised patients completed treatment through W100. Following early reductions in disease activity with guselkumab, durable improvements were observed across key PsA domains (swollen/tender joints, psoriasis, spinal pain, enthesitis/dactylitis) through W100. Response rates of therapeutically relevant targets generally increased through W100 with guselkumab Q4W/Q8W: Disease Activity Index for PsA low disease activity (LDA) 62%/59%, enthesitis resolution 61%/70%, dactylitis resolution 72%/83%, 100% improvement in Psoriasis Area and Severity Index 59%/53%, Psoriatic Arthritis Disease Activity Score LDA 51%/49% and minimal disease activity 38%/40%. Through W112, no cases of IBD developed among guselkumab-randomised patients and one case of uveitis was reported.

CONCLUSION

In biologic-naïve patients with active PsA, guselkumab provided early and durable improvements in key GRAPPA-recognised domains through 2 years, with substantial proportions achieving important treatment targets.

Guselkumab-Treated Patients with Plaque Psoriasis Who Achieved Complete Skin Clearance for ≥ 156 Consecutive Weeks: A Post-Hoc Analysis From the VOYAGE 1 Clinical Trial

BACKGROUND

Treatment of moderate-to-severe plaque psoriasis with biologics, such as guselkumab, has demonstrated greater efficacy over traditional non-biologic treatments. However, given patient diversity, greater understanding of the relationship between patient characteristics, positive clinical outcomes, and long-term response to biologics is crucial for optimizing treatment choices.

MATERIALS AND METHODS

This post-hoc analysis of the 5-year VOYAGE 1 clinical trial compares baseline characteristics of patients maintaining a Psoriasis Area and Severity Index (PASI) score of 0 at all visits for ≥ 156 consecutive weeks (PASI = 0 group) with those that never achieve PASI = 0 (comparator group), using descriptive statistics and a multiple logistic regression model. Guselkumab plasma trough concentrations in both response groups were assessed from Weeks 4-156.

RESULTS

Of patients who started guselkumab treatment at Week 0 or at Week 16 after switching from placebo, 22.7% (112/494) maintained PASI = 0 for ≥ 156 consecutive weeks. Numerical differences in baseline characteristics, including age, obesity, diabetes, PASI score, disease duration, smoking status, and psoriatic arthritis comorbidity, were identified between the PASI = 0 group and comparator group. Plasma guselkumab levels were consistently higher in the PASI = 0 group. Multiple logistic regression analysis revealed absence of diabetes, lower Dermatology Life Quality Index score at baseline, and higher Week 4 guselkumab plasma concentration as significantly (p < 0.05) associated with the PASI = 0 group.

CONCLUSION

A substantial (22.7%) number of guselkumab-treated patients in the VOYAGE 1 clinical trial maintained complete skin clearance for a consecutive period of ≥ 156 weeks. Factors associated with this outcome may suggest clinical benefits of holistic treatment approaches.

A systematic review of 454 randomized controlled trials using the Dermatology Life Quality Index: experience in 69 diseases and 43 countries

BACKGROUND

Over 29 years of clinical application, the Dermatology Life Quality Index (DLQI) has remained the most used patient-reported outcome (PRO) in dermatology due to its robustness, simplicity and ease of use.

OBJECTIVES

To generate further evidence of the DLQI's utility in randomized controlled trials (RCTs) and to cover all diseases and interventions.

METHODS

The methodology followed PRISMA guidelines and included seven bibliographical databases, searching articles published from 1 January 1994 until 16 November 2021. Articles were reviewed independently by two assessors, and an adjudicator resolved any opinion differences.

RESULTS

Of 3220 screened publications, 454 articles meeting the eligibility criteria for inclusion, describing research on 198 190 patients, were analysed. DLQI scores were primary endpoints in 24 (5.3%) of studies. Most studies were of psoriasis (54.1%), although 69 different diseases were studied. Most study drugs were systemic (85.1%), with biologics comprising 55.9% of all pharmacological interventions. Topical treatments comprised 17.0% of total pharmacological interventions. Nonpharmacological interventions, mainly laser therapy and ultraviolet radiation treatment, comprised 12.2% of the total number of interventions. The majority of studies (63.7%) were multicentric, with trials conducted in at least 42 different countries; 40.2% were conducted in multiple countries. The minimal clinically importance difference (MCID) was reported in the analysis of 15.0% of studies, but only 1.3% considered full score meaning banding of the DLQI. Forty-seven (10.4%) of the studies investigated statistical correlation of the DLQI with clinical severity assessment or other PRO/quality of life tools; and 61-86% of studies had within-group scores differences greater than the MCID in 'active treatment arms'. The Jadad risk-of-bias scale showed that bias was generally low, as 91.8% of the studies had Jadad scores of ≥ 3; only 0.4% of studies showed a high risk of bias from randomization. Thirteen per cent had a high risk of bias from blinding and 10.1% had a high risk of bias from unknown outcomes of all participants in the studies. In 18.5% of the studies the authors declared that they followed an intention-to-treat protocol; imputation for missing DLQI data was used in 34.4% of studies.

CONCLUSIONS

This systematic review provides a wealth of evidence of the use of the DLQI in clinical trials to inform researchers' and -clinicians' decisions for its further use. Recommendations are also made for improving the reporting of data from future RCTs using the DLQI.

Effectiveness and Safety of Biological Therapies in Very Severe Plaque Psoriasis: A Real-Life Retrospective Study

Psoriasis can have a significant impact on quality of life and productivity, especially with increased severity. However, there is limited evidence on biologics' efficacy in highly severe cases compared to moderate-to-severe ones. This study aimed to evaluate the effectiveness and safety of novel biological therapies in very severe psoriasis. We conducted a retrospective analysis on patients ≥ 18 years old affected by very severe psoriasis who had received a biological agent for at least 16 weeks. We used PASI to assess disease severity and effectiveness at weeks 16, 52, 104, and 156. Safety was evaluated by tracking treatment discontinuation rates and adverse events. This study included 29 males and 11 females, with a mean age of 55.80 years (SD 13.82). Cardiometabolic diseases were the most common comorbidities (25.00%). Twenty-eight (70.00%) patients had psoriasis involvement in at least one difficult-to-treat area. All patients completed 16 weeks of treatment. The mean PASI was 31.60 (SD 2.57) at baseline, 3.48 (SD 4.13) at week 16, 0.58 (SD 1.70) at week 52, 0.77 (SD 1.66) at week 104, and 1.29 (SD 2.12) at week 156. PASI90 and 100 were achieved by 52.50% and 30.00% of patients at week 16, by 96.15% and 80.77% at week 52, by 93.33% and 66.67% at week 104, and by 85.71% and 42.86% at week 156. PASIs ≤ 2 were achieved by 50.00% of patients at week 16, 88.46% at week 52, 86.67% at week 104, and 85.71% at week 156. Only two patients discontinued biologics due to complete remission, and mild AEs were reported by four patients. Our findings show that biologics are effective and well tolerated for treating very severe psoriasis, maintaining long-term effectiveness.

Implementing well-being in the management of psoriasis: An expert recommendation

Psoriasis causes detriment in a person's physical, mental and social health which impairs their quality of life (QoL). However, the current psoriasis management may not adequately address all relevant health domains. Since the goal of healthcare is to restore or maintain health, health outcomes should include all areas of the patient's overall health. Life satisfaction, QoL and patient well-being are essential to a comprehensive approach to the disease. With the inclusion of more people-centred policies, care of patients with psoriasis should evolve towards a holistic and integrated assessment of the disease impact, including subjective measures of well-being in order to encompass all aspects of health. The main objective of this expert review is to give the concept of well-being a place as an entity within the holistic therapeutic approach for patients with psoriasis. Identifying and defining common goals beyond the skin with the patient and testing them throughout the course of treatment will benefit and enhance treatment success. We propose a series of recommendations for application in clinical practice, providing tangible clinical guidance for implementing well-being in the management of psoriasis. Among the recommendations are the need to initially listen to the patient, to know their level of empowerment or what they want to achieve, their preferences in decision making, the evaluation of not only the physical but also the emotional impact of the disease (well-being), the definition of the aspects that can generate a cumulative deterioration of the disease throughout life, and a continuous assessment of the patient's preferences with the opinion of the expert clinician and the integration of the knowledge of external clinical evidence.

Long-Term Safety of Guselkumab in Patients with Psoriatic Disease: An Integrated Analysis of Eleven Phase II/III Clinical Studies in Psoriasis and Psoriatic Arthritis

INTRODUCTION

The benefit/risk profiles of biologics can be affected by comorbidities, certain demographic characteristics, and concomitant medications; therefore, it is important to evaluate the long-term safety profiles of biologics across broad patient populations. Guselkumab was well tolerated and efficacious across individual pivotal clinical studies in adults with moderate-to-severe psoriasis and/or active psoriatic arthritis (PsA).

OBJECTIVES

The objective of the current analysis was to evaluate guselkumab safety in a large population of patients with psoriatic disease by pooling adverse event (AE) data from 11 phase II/III studies (seven in psoriasis; four in PsA).

METHODS

Guselkumab was generally administered as 100 mg subcutaneous injections at Week 0, Week 4, then every 8 weeks (Q8W) in psoriasis studies and at Week 0, Week 4, then every 4 weeks (Q4W) or Q8W in PsA studies. Safety data were summarized for the placebo-controlled period (Weeks 0-16 in psoriasis; Weeks 0-24 in PsA) and through the end of the reporting period (up to 5 years in psoriasis; up to 2 years in PsA). Using the integrated data, incidence rates of key AEs were determined post hoc, adjusted for duration of follow-up, and reported per 100 patient-years (PYs). AE rates were also determined in subgroups of patients defined by sex, age, body mass index (BMI), and prior biologic use.

RESULTS

During the placebo-controlled period, 1061 patients received placebo (395 PYs) and 2257 received guselkumab (856 PYs). Through the end of the reporting period, 4399 guselkumab-treated patients contributed 10,787 PYs of follow-up. During the placebo-controlled period, in the guselkumab and placebo groups, respectively, rates of AEs were 281 versus 272/100 PYs, and infections were 76.0 versus 72.2/100 PYs. Rates of serious AEs (5.6 vs. 7.8/100 PYs), AEs leading to discontinuation (4.9 vs. 6.6/100 PYs), serious infections (1.0 vs. 2.3/100 PYs), malignancy (0.59 vs. 0.25 patients/100 PYs), and major adverse cardiovascular events (MACE; 0.35 vs. 0.25/100 PYs) were low and comparable between guselkumab and placebo. Among guselkumab-treated patients, safety event rates through the end of the reporting period were numerically lower than or comparable with rates observed during the placebo-controlled period: AEs, 164/100 PYs; infections, 61.2/100 PYs; serious AEs, 5.4/100 PYs; AEs leading to discontinuation, 1.8/100 PYs; serious infections, 1.0/100 PYs; malignancy, 0.6/100 PYs; and MACE, 0.3/100 PYs. No AEs of Crohn's disease, ulcerative colitis, or active tuberculosis were reported among guselkumab-treated patients. In the psoriasis studies, no opportunistic infections were reported among guselkumab-treated patients. Three AEs of opportunistic infections were reported in guselkumab-treated patients with PsA (0.14/100 PYs; all after Week 52 in DISCOVER-2). AE rates were largely consistent across subgroups of guselkumab-treated patients defined by sex, age, BMI, and prior biologic use.

CONCLUSIONS

In this analysis of 4399 guselkumab-treated patients with psoriatic disease followed for 10,787 PYs, guselkumab had a favorable AE profile. AE rates were similar between guselkumab- and placebo-treated patients and were consistent throughout long-term guselkumab treatment and across broad subgroups of patients with psoriatic disease.

Long-term efficacy and safety of guselkumab in Chinese patients with moderate-to-severe plaque psoriasis

Background

Randomized controlled trials indicated guselkumab, the first anti-interleukin-23 monoclonal antibody, is efficacious in plaque psoriasis. However, guselkumab's performance in real life is scarcely examined, especially in China.

Objectives

This work aimed to assess the long-term effectiveness of guselkumab in actual clinical practice in China.

Methods

A retrospective study was performed for plaque psoriasis cases administered guselkumab in Shanghai Skin Disease Hospital between January 2020 and September 2022.

Results

A total of 37 patients were included (29 men, 78.4%), with a mean follow-up period of 72.3 ± 26.7 weeks (range of 12-108 weeks). At baseline, clinical examination revealed a mean PASI of 12.3 ± 7.1, a mean BSA of 17.1 ± 18.1, and a mean DLQI of 7.7 ± 4.3. Twenty-two (62.9%) and 17 (48.6%) cases achieved PASI 90 and PASI 100 responses at week 28. From weeks 60 to 92, >80% of cases achieved PASI 90 and PASI 100 responses. Regarding safety, no cases of serious AEs were recorded. A total of nine cases (24.3%) had different abnormal results in HBV markers, and two were T-SPOT positive. There was no hepatitis B virus or tuberculosis outbreak in these patients.

Conclusion

This real-life study confirmed the long-term efficacy and safety of guselkumab in daily clinical practice.

Long-term safety and efficacy of risankizumab for the treatment of moderate-to-severe plaque psoriasis: Interim analysis of the LIMMitless open-label extension trial up to 5 years of follow-up

BACKGROUND

Psoriasis is a chronic, inflammatory skin disease often requiring long-term therapy.

OBJECTIVE

To evaluate the long-term safety and efficacy of risankizumab in patients with psoriasis.

METHODS

LIMMitless is an ongoing phase 3, open-label extension study evaluating the long-term safety and efficacy of continuous risankizumab 150 mg every 12 weeks for adults with moderate-to-severe plaque psoriasis following multiple phase 2/3 base studies. This interim analysis assessed safety (ie, monitored treatment-emergent adverse events [TEAEs]) through 304 weeks. Efficacy assessments included determining the proportion of patients who achieved ≥90% or 100% improvement in Psoriasis Area and Severity Index (PASI 90/100), static Physician's Global Assessment of clear/almost clear (sPGA 0/1), and Dermatology Life Quality Index of no effect on patient's life (DLQI 0/1) through 256 weeks.

RESULTS

Among 897 patients randomized to risankizumab in the base studies, 706 were still ongoing at data cutoff. Rates of TEAEs, TEAEs leading to discontinuation, and TEAEs of safety interest were low. At week 256, 85.1%/52.3% of patients achieved PASI 90/100, respectively, 85.8% achieved sPGA 0/1, and 76.4% achieved DLQI 0/1.

LIMITATIONS

Open-label study with no placebo or active-comparator group.

CONCLUSIONS

Long-term continuous risankizumab treatment for up to 5 years was well tolerated and demonstrated high and durable efficacy.

Five-year Maintenance of Clinical Response and Consistent Safety Profile for Guselkumab in Asian patients with Psoriasis from VOYAGE 1 and VOYAGE 2

INTRODUCTION

Guselkumab is a human monoclonal antibody against IL-23 used in the treatment of moderate-to-severe psoriasis. This post-hoc analysis evaluated the efficacy and safety of guselkumab in the Asian subpopulation of VOYAGE 1 and VOYAGE 2 through 5 years.

METHODS

The proportions of guselkumab-treated Asian patients (VOYAGE 1 and 2) achieving Psoriasis Area and Severity Index (PASI) 90 and PASI 100, Investigator's Global Assessment (IGA) scores of 0/1 and 0, and Dermatology Life Quality Index (DLQI) scores of 0/1 (week 100 through week 252) were assessed. Non-responders were patients who met the treatment failure rules. Efficacy endpoints were analyzed using the as-observed methodology (no missing data imputation) for both studies and using non-responder imputation (for patients with any missing data) in VOYAGE 1. Safety outcomes were based on pooled data through week 252.

RESULTS

Response rates through week 252 for 199 Asian patients in the guselkumab group in VOYAGE 1 and VOYAGE 2, respectively, were 76.8% and 80.6% (PASI 90), 26.8% and 38.7% (PASI 100), 64.3% and 87.1% (IGA 0/1), and 26.8% and 45.2% (IGA 0). DLQI (0/1) at week 252 was achieved by 52.7% of patients in VOYAGE 1 and 61.3% in VOYAGE 2, while DLQI (0) at week 252 was achieved by 32.7% of patients in VOYAGE 1 and 40.3% in VOYAGE 2. The safety profile was similar to the global population and remained consistent through 5 years. Asian patients were followed for a total of 814 patient-years (PY). Over 85% of the guselkumab-treated patients continued treatment through week 264. The rate of serious adverse events (AEs) at week 252 was 3.07/100 PY. Rates of AEs of interest were low: serious infections, 0.74/100 PY; nonmelanoma skin cancer (NMSC), no patients; malignancies other than NMSC, 0.12/100 PY; and no major adverse cardiovascular events (MACE).

CONCLUSION

These analyses confirm a continuous response over 5 years, indicating that guselkumab shows therapeutic longevity in Asian patients requiring long-term treatment for moderate-to-severe psoriasis.

Durability of Near-Complete Skin Clearance in Patients with Psoriasis Using Systemic Biologic Therapies: Real-World Evidence from the CorEvitas Psoriasis Registry

INTRODUCTION

Near-complete skin clearance has become a rapidly achievable treatment goal for patients with psoriasis receiving systemic biologic therapies. However, real-world evidence for durability of near-complete skin clearance and risk factors associated with loss of near-complete skin clearance is limited.

METHODS

This study described durability of near-complete skin clearance (≥ 90% improvement in Psoriasis Area and Severity Index from initiation; PASI90) and identified clinical factors or patient characteristics associated with loss of PASI90 among patients with psoriasis from the CorEvitas Psoriasis Registry (April 2015-August 2021). Included patients had PASI > 5 at biologic initiation and achieved PASI90 at approximately 6 months from initiation (index). A Kaplan-Meier estimate described time to loss of treatment response over 24 months follow-up from index. Proportional hazards regression was used to identify independent predictors of loss of treatment response.

RESULTS

This study included 687 patient initiations (instances of patients initiating a biologic). Following achievement of PASI90, treatment response was maintained in more than half of patient initiations (54%). Treatment response was maintained at 6, 12, and 18 months from index in an estimated 73% (95% [confidence interval] CI 70-77%), 60% (95% CI 56-63%), and 50% (95% CI 47-54%) of patient initiations, respectively. Adjusted hazards regression suggested non-White race, full-time employment, greater body weight, concomitant psoriatic arthritis, prior use of biologics, and clinically meaningful skin symptoms were associated with loss of treatment response.

CONCLUSIONS

Among real-world patients with psoriasis who achieved PASI90 with biologic therapy, about one-quarter lost response at 6 months, and half lost response at 18 months. Prior use of a biologic therapy and clinically meaningful skin symptoms at index, including itch and skin pain, were associated with loss of treatment response. Therefore, dermatologists may consider focusing on patient-reported symptoms as part of any intervention designed to reduce the likelihood of loss of response to biologic therapies.

Efficacy of Guselkumab in Treating Nails, Scalp, Hands, and Feet in Patients with Psoriasis and Self-reported Psoriatic Arthritis

INTRODUCTION

The aim of this study was to evaluate guselkumab efficacy on regional psoriasis in a subset of psoriasis patients with a self-reported psoriatic arthritis (PsA) diagnosis.

METHODS

In the phase 3 VOYAGE-1 and -2 studies, at week (W)0, patients with moderate-to-severe psoriasis were randomized to guselkumab 100 mg, placebo → guselkumab 100 mg at W16 through W44, or adalimumab 80 mg then 40 mg at W1 through W48 (VOYAGE-1) or W24 (VOYAGE-2). Pooled efficacy outcomes, including scalp-specific Investigator's Global Assessment (ss-IGA), hands and/or feet Physician's Global Assessment (hf-PGA), fingernail PGA (f-PGA), Nail Psoriasis Area and Severity Index (NAPSI), and Dermatology Life Quality Index (DLQI), were compared (nominal p-values) through W24 in patients with self-reported PsA diagnosis. Response rates/percentage improvement from baseline were determined, employing treatment failure rules and non-response/no improvement data imputation.

RESULTS

A total of 76, 153, and 106 psoriasis patients with self-reported PsA were randomized to the placebo, guselkumab, or adalimumab groups, respectively; the baseline characteristics of patients in all three arms were comparable. At W16, a greater proportion of guselkumab- versus placebo-treated patients achieved ss-IGA 0/1 (80.6% vs. 22.7%, p < 0.001), hf-PGA 0/1 (68.9% vs. 14.8%, p < 0.001), f-PGA 0/1 (47.6% vs. 17.0%, p < 0.001), and DLQI 0/1 (45.6% vs. 2.7%, p < 0.001) responses; mean percentage NAPSI improvement was also greater with guselkumab (39.5% vs. 6.5%, p < 0.001). At W24, patients receiving guselkumab had higher ss-IGA 0/1 (77.5% vs. 58.5%, p = 0.003) and DLQI 0/1 (47.7% vs. 34.3%, p = 0.024) response rates versus those receiving adalimumab. Response rates/mean percentage improvements at W48 (VOYAGE-1) were numerically greater with guselkumab than adalimumab (e.g., NAPSI improvement: 75.6% vs. 60.9%).

CONCLUSIONS

Guselkumab-treated patients with psoriasis and self-reported PsA showed meaningful improvements in nail, scalp, and palmoplantar psoriasis.

Depression, a major comorbidity of psoriatic disease, is caused by metabolic inflammation

Psoriatic disease is a chronic, systemic immune-mediated inflammatory disorder comprising three major domains, skin, vascular and bone/joint inflammation. It is known for a long time that psoriatic disease is associated with a number of conditions such as hypertension, dyslipidemia, diabetes (metabolic syndrome) and depression. Up to one out of five people with psoriasis show concomitant depression. In the past, this was attributed to psychological stress of suffering from a chronic condition that is often visible and itchy, leading to stigmatization and adding to a significant burden of disease. Recent data provide evidence that depression associated with psoriatic disease is linked to the specific inflammatory pattern with IL-23, IL-17 family cytokines, TNF, IL-6 and IL-8 causing neuroinflammation and subsequently depression or depressive behaviour and/or anxiety. Psoriatic disease shows a distinct pattern of immune cells (e.g. dendritic cells, Th17 cells, neutrophils), mediators (e.g. IL-17A/F, IL-23, TNF) and tissue-related factors in all major domains that is different from other inflammatory dermatoses. There is a striking similarity between the inflammatory pattern in psoriatic disease and neuroinflammation that leads to depression. A number of risk factors have been identified in psoriatic disease, the most important of which are obesity and tobacco smoking. Obesity is known as a major risk factor for depression and anxiety due to its inflammatory signature. Apart from psychotherapy and anti-depressive medication, targeted treatments for psoriasis, including TNF, IL-17 and IL-23 inhibitors, can improve depression/depressive symptoms. The review summarizes the current knowledge about depression as a comorbidity in psoriatic disease.

Efficacy of guselkumab in difficult-to-treat psoriasis regions: Data from VOYAGE 1 and VOYAGE 2 Asian subpopulations

Patients with psoriasis were randomized to guselkumab, placebo or adalimumab in the VOYAGE 1 and VOYAGE 2 studies. In this post hoc analysis, difficult-to-treat psoriasis regions in the Asian subpopulation for both the guselkumab and adalimumab groups were compared with placebo at week 16 and the active treatment groups were compared at week 24. Endpoints included patients achieving scores of 0 or 1 (clear or near clear) or 0 (clear) on the scalp-specific Investigator's Global Assessment (ss-IGA), Physician's Global Assessment of the hands and/or feet (hf-PGA), and fingernail PGA (f-PGA), and percentage improvement in target Nail Psoriasis Severity Index (NAPSI) score through week 24. Efficacy was also assessed by prior biologic experience at baseline. A total of 199 eligible Asian patients were included. The proportion of patients achieving "clear" or "near clear" with guselkumab was superior to adalimumab at week 24 for scalp psoriasis ss-IGA (Asian patients, 72 [85.7%] vs 35 [67.3%], P = 0.004), hands and/or feet psoriasis hf-PGA (29 [82.9%] vs 16 [61.5%], P = 0.054), and similar for fingernail psoriasis f-PGA (28 [63.6%] vs 17 [54.8%], P = 0.412). Guselkumab mean improvements in NAPSI were comparable to adalimumab (39.9% vs 35.9%, P = 0.618). Overall, the complete clearance response of scalp, and hands and/or feet at week 24 occurred in a greater proportion of patients in the guselkumab group, irrespective of baseline biologic status (treatment-naïve or treatment-experienced). Guselkumab was superior to adalimumab for the treatment of scalp, and hands and/or feet psoriasis, and proportionally higher for fingernail psoriasis. Findings were comparable to the global study population.

Effectiveness, safety and quality-of-life effects of guselkumab and ustekinumab in patients with psoriasis: Week 104 results from the non-interventional, prospective, German multicentre PERSIST study

BACKGROUND

PERSIST was a prospective, non-interventional, real-world study of guselkumab and ustekinumab in adult patients with moderate-to-severe plaque psoriasis in Germany.

OBJECTIVES

To examine effectiveness, safety and quality-of-life (QoL) outcomes to Week (W) 104 of treatment with guselkumab and ustekinumab in patients with moderate-to-severe plaque psoriasis.

METHODS

Patients (≥18 years of age) received guselkumab or ustekinumab as per routine clinical practice. Outcomes to W104 were examined separately in guselkumab and ustekinumab recipients. An ad hoc exploratory analysis of outcomes with guselkumab versus ustekinumab was also performed following propensity score matching.

RESULTS

Overall, 302 and 313 patients received guselkumab and ustekinumab, respectively. Patients in both cohorts experienced improvements in disease activity and QoL that were maintained to W104, with 64.7% and 63.6% of guselkumab- and 54.6% and 64.4% of ustekinumab-treated patients achieving a Psoriasis Area and Severity Index (PASI) 90 response and a Dermatology Life Quality Index (DLQI) 0/1 score, respectively. Propensity score matching yielded well-balanced baseline characteristics except for prior biologic use, which was higher in guselkumab versus ustekinumab recipients (51.7% vs. 32.0%). Achievement of PASI ≤1 at W104 was more common in guselkumab versus ustekinumab recipients (58.7% vs. 49.7%). The W104 PASI90 response rate was 65.6% with guselkumab and 56.0% with ustekinumab; corresponding rates for PASI100 were 44.3% and 28.5%. In guselkumab recipients, response rates were higher in biologic-naïve versus biologic-experienced patients (PASI90, 77.1% vs. 53.4%; PASI100, 55.0% vs. 33.0%). A high level of response for QoL outcomes was observed for both treatments.

CONCLUSIONS

Ustekinumab and guselkumab led to improvements in physician-assessed and patient-reported outcomes that were sustained for up to 2 years, with no new safety signals identified. Following propensity score matching, greater improvements in PASI outcomes were observed with guselkumab versus ustekinumab. Improvements with guselkumab were highest in biologic-naïve patients, highlighting the value of early treatment.

Safety of guselkumab treatment for up to 5 years in patients with moderate-to-severe psoriasis: pooled analyses across seven clinical trials with more than 8600 patient-years of exposure

BACKGROUND

Guselkumab has demonstrated favourable safety and efficacy across individual clinical studies in adults with moderate-to-severe plaque psoriasis.

OBJECTIVES

To evaluate the safety of guselkumab in patients with psoriasis using pooled data from seven phase II/III studies (X-PLORE, VOYAGE 1, VOYAGE 2, NAVIGATE, ORION, ECLIPSE, Japan registration).

METHODS

All studies, except NAVIGATE and ECLIPSE (active comparator-controlled only), included a 16-week placebo-controlled period; X-PLORE, VOYAGE 1 and VOYAGE 2 included both placebo and active controls. In most studies, guselkumab-treated patients received 100-mg subcutaneous injections at week 0, week 4, and then every 8 weeks thereafter. Safety data were summarized for the placebo-controlled period (weeks 0-16) and through the end of the reporting period (up to 5 years). Incidence rates of key safety events were integrated post hoc, adjusted for the duration of follow-up and reported per 100 patient-years (PY).

RESULTS

During the placebo-controlled period, 544 patients received placebo (165 PY) and 1220 received guselkumab (378 PY). Through the end of the reporting period, 2891 guselkumab-treated patients contributed 8662 PY of follow-up. During the placebo-controlled period, in the guselkumab and placebo groups, respectively, rates of adverse events (AEs) were 346/100 PY and 341/100 PY, and infections were 95.9/100 PY and 83.6/100 PY. Rates of serious AEs (6.3/100 PY vs. 6.7/100 PY), AEs leading to discontinuation (5.0/100 PY vs. 9.7/100 PY), serious infections (1.1/100 PY vs. 1.2/100 PY), malignancy (0.5 patients/100 PY vs. 0.0 patients/100 PY) and major adverse cardiovascular events (MACE; 0.3/100 PY vs. 0.0/100 PY) were low and comparable between guselkumab and placebo. Through the end of the reporting period, safety event rates were lower than or comparable to the placebo-controlled period in guselkumab-treated patients: AEs, 169/100 PY; infections, 65.9/100 PY; serious AEs, 5.3/100 PY; AEs leading to discontinuation, 1.6/100 PY; serious infections, 0.9/100 PY; malignancy, 0.7/100 PY; and MACE, 0.3/100 PY. There were no cases of Crohn disease, ulcerative colitis, opportunistic infection or active tuberculosis related to guselkumab.

CONCLUSIONS

In this comprehensive analysis of 2891 guselkumab-treated patients with psoriasis followed for up to 5 years (8662 PY), guselkumab demonstrated favourable safety, consistent with previous reports. Safety event rates in guselkumab-treated patients were similar to those observed with placebo and were consistent throughout long-term treatment.

Guselkumab More Effectively Neutralizes Psoriasis-Associated Histologic, Transcriptomic, and Clinical Measures than Ustekinumab

Given the key role of the IL-23/Th17 axis in the pathogenesis of moderate-to-severe plaque psoriasis, several specific inhibitors of the p19 subunit of IL-23 have been approved to treat this chronic inflammatory disease. Clinical data indicate that guselkumab, one such selective IL-23 inhibitor, achieves greater clinical efficacy compared with ustekinumab, which inhibits both IL-12 and IL-23 via binding their shared p40 subunit. To understand mechanisms underlying the enhanced efficacy observed with the p19 subunit of IL-23-specific inhibition, we explored cellular and molecular changes in skin of psoriasis patients treated with ustekinumab or guselkumab and in ustekinumab inadequate responders (Investigator's Global Assessment of psoriasis score ≥ 2) subsequently treated with guselkumab (ustekinumab→guselkumab). Skin biopsies were collected pretreatment and posttreatment to assess histologic changes and molecular responses in ustekinumab- and guselkumab-treated patients. Serum cytokines and skin transcriptomics from the subset of ustekinumab→guselkumab-treated patients were also analyzed to characterize differential treatment effects. Ustekinumab and guselkumab demonstrated differential effects on secretion of pathogenic Th17-related cytokines induced by IL-23 in in vitro assays, which suggest guselkumab is a more potent therapeutic agent. Consistent with these findings, guselkumab elicited a significantly greater reduction in cellular and molecular psoriasis-related disease indicators than ustekinumab. In ustekinumab→guselkumab patients, suppression of serum IL-17A and IL-17F levels and neutralization of molecular scar and psoriasis-related gene markers in skin were significantly greater compared with patients continuing ustekinumab. This comparative study demonstrates that guselkumab inhibits psoriasis-associated pathology, suppresses Th17-related serum cytokines, and normalizes the psoriasis skin gene expression profile more effectively than ustekinumab.

Guselkumab for treatment of moderate-to-severe plaque psoriasis: real-life effectiveness and drug-survival for up to 148 weeks

BACKGROUND

Real-world data are useful to guide the management of psoriasis. Here, we present data on the effectiveness and survival of guselkumab in moderate-to-severe chronic plaque psoriasis for up to 148 weeks.

RESEARCH DESIGN AND METHODS

Cross-sectional study of 122 patients receiving guselkumab (100 mg at weeks 0 and 4, and then every 8 weeks thereafter) for>12 weeks, from November 2018 to April 2022.

MAIN OUTCOME MEASURES

Clinical features and drug survival were analyzed up to 148 weeks.

RESULTS

Obese patients (32.8%) and those receiving prior biologics (64.8%) were included. Guselkumab treatment was associated with a rapid decrease in PASI, from 16.2 to 3.2 at week 12, and long-term improvements in all subgroups (97.6%, 82.9%, and 63.4% of patients, respectively, achieved PASI 75, 90, and 100 after 148 weeks). More non-obese than obese patients achieved PASI 100 at week 148 (86.4% vs 38.9%), as did bio-naïve vs bio-experienced patients (86.7% vs 50.0%). Previous biologic therapy was a negative prognostic factor for achieving PASI 100 over the long-term by multivariate analysis (p = 0.005). Overall, 96% of patients were on treatment after 2 years.

CONCLUSIONS

Real-world data confirm the long-term effectiveness of guselkumab in patients with psoriasis.

Effectiveness of Guselkumab Therapy among Patients with Plaque Psoriasis with Baseline IGA Score ≥ 2 in the CorEvitas Psoriasis Registry

INTRODUCTION

In clinical trials, treatment with the interleukin-23 inhibitor guselkumab was associated with significantly improved disease severity and patient-reported outcome measures (PROMs) among patients with moderate-to-severe plaque psoriasis. However, limited information is available regarding the real-world effectiveness of guselkumab among patients with psoriasis of mild, moderate, and severe Investigator's Global Assessment (IGA) severities living in the USA and Canada.

METHODS

Patients participating in the CorEvitas Psoriasis Registry between 18 July 2017 and 10 July 2019 who met the following criteria were included: IGA ≥ 2 (mild or greater disease severity), initiated guselkumab at a registry (index) visit, and had a registry follow-up visit after persistent guselkumab treatment for 9 to 12 months. Data were collected for patient demographics, disease characteristics, treatment history, disease activity, and PROMs. At follow-up, outcome measure response rates and mean changes from the index visit were calculated.

RESULTS

Among 130 patients, the mean age was 50.2 years, 39.2% were female, and 56.9% had a body mass index ≥ 30 kg/m2. Mean psoriasis duration was 17.5 years and 79.2% of patients had previously received one or more biologic therapy. At the index visit, mean IGA, Psoriasis Area Severity Index (PASI), and Dermatology Life Quality Index (DLQI) scores were 3.0, 9.9, and 8.0, respectively. At follow-up, IGA 0/1 and IGA 0 were achieved by 64.6% and 36.2% of patients, respectively. PASI 75, 90, and 100 were achieved by 61.5%, 46.9%, and 36.9% of patients; 55.4% had maintained or achieved DLQI 0/1. Mean improvements were observed in all evaluated disease activity outcomes and PROMs, with all differing significantly from zero except for the percent of work hours missed due to psoriasis.

CONCLUSION

In this real-world study, patients with a baseline IGA score ≥ 2 experienced improvements in disease activity and PROMs after 9-12 months of persistent guselkumab treatment.

Efficacy and safety of combination targeted therapies in immune-mediated inflammatory disease: the COMBIO study

BACKGROUND

Use of a combination of targeted therapies (COMBIO) in patients with refractory/overlapping immune-mediated inflammatory diseases (IMIDs) has increased, but reported data remain scarce. We aimed to assess effectiveness and safety of COMBIO in patients with IMIDs.

METHODS

We conducted a French ambispective multicenter cohort study from September 2020 to May 2021, including adults' patients with 1 or 2 IMIDs and treated at least 3-month with COMBIO.

RESULTS

Overall, 143 patients were included. The most common IMIDs were Crohn's disease (63.6%), axial spondyloarthritis (37.7%), and ulcerative colitis (14%). Half of patients had only one IMID, of which 60% were Crohn's disease. Mean duration of COMBIO was 274.5±59.3 weeks, and COMBIO persistence at 104 weeks was estimated at 64.1%. The most frequent COMBIOs combined anti-TNF agents with vedolizumab (30%) or ustekinumab (28.7%). Overall, 50% of patients achieved significant and 27% mild-to-moderate improvement in patient-reported outcomes. Extended duration of COMBIO (aOR=1.09; 95% CI: 1.03-1.14; p=0.002) and diagnoses of two IMIDs (aOR=3.46; 95%CI: 1.29-9.26; p=0.013) were associated with significant improvement in patient-reported outcomes. Incidence of serious infection during COMBIO was 4.51 per 100 person-years (95% CI 2.20-8.27) and 5 COMBIOs were discontinued due to adverse events.

CONCLUSIONS

COMBIO can be effective and safe in patients with refractory/overlapping IMIDs.

Anti-IL 23 biologics for the treatment of plaque psoriasis

INTRODUCTION

Psoriasis is a chronic inflammatory disease that can drastically affect a patient's quality-of-life and is associated with multiple comorbid conditions. The most common form of psoriasis is plaque psoriasis, commonly presenting as sharply demarcated, erythematous plaques with overlying silvery scale on the trunk, extensor surfaces, limbs, and scalp. Although initially limited to oral therapies, the choices in systemic therapies for moderate-to-severe plaque psoriasis have evolved with biologic immunotherapies being the main focus.

AREAS COVERED

In this review, we describe the IL-23/Th17 axis and IL-23 inhibitors as targets for a growing family of biologics. This family includes the FDA-approved medications ustekinumab, guselkumab, tildrakizumab, and risankizumab. We will review the safety and efficacy of these medications throughout various Phase 1,2, and 3, trials for moderate-to-severe psoriasis. A literature search of PubMed was utilized for the following terms: 'psoriasis and IL-23,' 'ustekinumab,' 'guselkumab,' 'tildrakizumab,' and 'risankizumab.' We also searched for clinical trials involving IL-23 inhibitors registered at ClinicalTrials.gov.

EXPERT OPINION

Anti-IL 23 therapy, especially anti-p19 monoclonal antibodies, should be considered first-line therapy for moderate-to-severe plaque psoriasis due to their efficacy and relative safety. More research is required to expand the scope of anti-p19 therapy to pediatric populations and additional indications such as psoriatic arthritis.

Real-world outcomes in patients with moderate-to-severe plaque psoriasis treated with guselkumab for up to 1 year

BACKGROUND

Real-world data on guselkumab, especially at times >6 months, are limited.

RESEARCH DESIGN AND METHODS

We performed a longitudinal, retrospective analysis on 307 patients with moderate-severe chronic plaque psoriasis (Psoriasis Area Severity Index [PASI] >10) treated with guselkumab for up to 12 months.

MAIN OUTCOME MEASURES

PASI 75, PASI 90, and PASI 100 were assessed at baseline and at 4, 12, 20, 28, 36, 44, and 52 weeks.

RESULTS

At 12 weeks, PASI 75, PASI 90, and PASI 100 were achieved in 56.4%, 33.6%, and 24.1% of patients, respectively. At 52 weeks, PASI 75, PASI 90, and PASI 100 were achieved in 82.7%, 68.7%, and 51.1% of patients, respectively. Patients without comorbidities and those naïve to previous biological therapy had better responses. The mean Dermatology Life Quality Index score decreased from 14.0 at baseline to 3.1 at 12 weeks and 1.6 at 6 months, which was maintained at later times. Similar improvements were seen in pruritus visual analog scale.

CONCLUSIONS

Guselkumab maintains its efficacy for up to 12 months among responders in a real-world cohort of patients with moderate-severe plaque psoriasis, confirming data from prior real-world studies with smaller cohorts and shorter duration of follow-up.

Long-Term Efficacy and Safety of Guselkumab for Moderate to Severe Psoriasis: A 3-Year Real-Life Retrospective Study

Introduction

Guselkumab safety and efficacy profiles in psoriasis have been showed by VOYAGE (1 and 2) trials. Although trial results have been already previously confirmed by real-life studies, long-term real-life data, and drug survival data about guselkumab are still poor.

Patients and Methods

We performed a 3-year retrospective study, with the aim of assessing guselkumab efficacy and safety profile in the management of plaque psoriasis in a real-life setting.

Results

Thirty-one patients completed the study. Both Psoriasis Area Severity Index (PASI) and Body Surface Area (BSA) statistically improved since week 16, and up to week 144 [PASI reduction from 16.4 ± 6.2 to 0.6 ± 0.9 (p < 0.0001) at week 144 while BSA from 33.2 ± 14.6 to 1.9 ± 1.4 (p < 0.0001)]. At week 12 PASI90 and PASI100 were achieved by 19 (61.3%) and 11 (35.4%) patients, respectively, as well as 24 (77.4%) and 18 (58.1%) subjects reached PASI 90 and PASI 100 at week 144. As regards the safety, no cases of injection site reaction, candida, serious AEs, malignancy, or major cardiovascular events were reported. Of note, mild AEs were collected with pharyngitis as the main one (7, 22.6%), followed by headache (5, 16.1%) and flu-like illness (5, 16.1%), all without requiring treatment discontinuation.

Conclusion

Our experience confirmed the efficacy and safety of guselkumab in daily clinical practice up to 3 years, suggesting this drug as an effective treatment option in psoriasis long-term management.

Sustained and improved guselkumab response in patients with active psoriatic arthritis regardless of baseline demographic and disease characteristics: pooled results through week 52 of two phase III, randomised, placebo-controlled studies

OBJECTIVES

To evaluate the efficacy through 52 weeks of guselkumab, an interleukin 23-p19 subunit inhibitor, in subgroups of pooled psoriatic arthritis (PsA) patients from the DISCOVER-1 and DISCOVER-2 trials defined by baseline patient characteristics.

METHODS

Adults with active PsA despite standard therapies were enrolled in DISCOVER-1 (≥3 swollen and ≥3 tender joints, C reactive protein (CRP) level ≥0.3 mg/dL) and DISCOVER-2 (≥5 swollen and ≥5 tender joints, CRP ≥0.6 mg/dL, biological-naïve). Randomised patients received 100 mg guselkumab at weeks 0, 4, and then every 4 or 8 weeks (Q4W/Q8W) or placebo. Guselkumab effects on joint (ACR20/50/70), skin (IGA 0/1, IGA 0), patient-reported outcome (Health Assessment Questionnaire Disability Index/Functional Assessment of Chronic Illness Therapy-Fatigue) and disease severity (minimal disease activity/PsA Disease Activity Score low disease activity) endpoints were evaluated by patient sex, body mass index, PsA duration, swollen/tender joint counts, CRP level, percent body surface area with psoriasis, Psoriasis Area and Severity Index score, and conventional synthetic disease-modifying antirheumatic drug use at baseline.

RESULTS

Baseline patients characteristics in DISCOVER-1 (N=381) and DISCOVER-2 (N=739) were well balanced across randomised groups. At week 24, 62% (232/373) and 60% (225/375), respectively, of guselkumab Q4W-treated and Q8W-treated patients pooled across DISCOVER-1 and DISCOVER-2 achieved the primary endpoint of ACR20 response versus 29% (109/372) of placebo-treated patients. Guselkumab treatment effect at week 24 was observed across patient subgroups. Within each patient subgroup, response rates across all disease domains were sustained or increased at week 52 with both guselkumab regimens.

CONCLUSIONS

Guselkumab Q4W and Q8W resulted in robust and sustained improvements in PsA signs and symptoms consistently in subgroups of patients defined by diverse baseline characteristics.

Guselkumab is efficacious and safe in psoriasis patients who failed anti-IL17: a 52-week real-life study

BACKGROUND

Interleukin (IL)23/Th17 axis is the leading actor of psoriasis pathogenesis. Guselkumab is the first anti-IL23 approved for psoriasis. Anti-IL23 and anti-IL17 partially share their therapeutic target currently appearing as the most efficacious available psoriasis treatments. Real-life data on guselkumab performance in anti-IL17 failure patients are scant.

METHODS

A 52-week real-life single-center retrospective study was performed to evaluate the long-term efficacy and safety of guselkumab in patients who previously failed anti-IL17.

RESULTS

A total of 44 patients were enrolled (28 male, 63.6%; mean age 59.0 ± 10.2years). A statistically significant improvement of Psoriasis Area Severity Index (PASI) and Body Surface Area (BSA) was assessed at each follow-up (PASI decreased from 13.9 ± 8.1 to 0.9 ± 0.7 at week52 while BSA from 24.3 ± 19.6 to 1.3 ± 1.4, p < 0.001). Nail Psoriasis Severity Index (NAPSI) improvement was collected as well, even if being statistically significative only at week28 and thereafter [2.9 ± 6.2 at baseline, 0.9 ± 1.5 at week28, (p < 0.05)]. Only 3(6.8%) patients discontinued guselkumab due to secondary inefficacy. No cases of serious Adverse Events were assessed.

CONCLUSION

Our real-life study confirmed the efficacy and safety of guselkumab in daily clinical practice suggesting it as a valuable weapon also in psoriasis patients who previously failed anti-IL17 treatments.

Consistent safety profile with up to 5 years of continuous treatment with guselkumab: Pooled analyses from the phase 3 VOYAGE 1 and VOYAGE 2 trials of patients with moderate-to-severe psoriasis

BACKGROUND

Guselkumab effectively treats moderate-to-severe psoriasis.

OBJECTIVE

To evaluate the cumulative safety experience of guselkumab using pooled data from the VOYAGE 1 and 2 studies through 5 years.

METHODS

Patients were randomized to guselkumab, placebo with crossover to guselkumab at week 16, or adalimumab. The studies were identical through week 24. VOYAGE 1 evaluated continuous guselkumab treatment (adalimumab-crossover-to-guselkumab at week 52), while VOYAGE 2 assessed randomized withdrawal/retreatment (weeks 28-76). Open-label guselkumab treatment was administered starting at week 52 in VOYAGE 1 and week 76 in VOYAGE 2 and continued through week 252. Pooled safety data were adjusted by exposure and analyzed in the guselkumab groups, including placebo-crossover-to-guselkumab (n = 1221) and adalimumab-crossover-to-guselkumab (n = 500), through week 264.

RESULTS

Patients were followed for a total of 7166 patient-years (PY). Overall, 1349 of 1721 guselkumab-treated patients (78.4%) continued treatment through week 252. The rates of adverse and serious adverse events were 149/100 PY and 5.01/100 PY, respectively. Rates of adverse events of interest were low: serious infections (0.85/100 PY), nonmelanoma skin cancer (0.34/100 PY), malignancies other than nonmelanoma skin cancer (0.45/100 PY), and major adverse cardiovascular events (0.29/100 PY). Year-to-year variability was evident, but no increasing trend was observed.

LIMITATIONS

No direct treatment comparisons were possible after week 52.

CONCLUSION

The safety profile remained consistent and favorable during 5 years of continuous guselkumab treatment of psoriasis.
