Efficacy of risankizumab across subgroups in patients with active psoriatic arthritis: a post hoc integrated analysis of the phase 3 KEEPsAKE 1 and KEEPsAKE 2 randomized controlled trials

In the KEEPsAKE 1 (NCT03675308) and KEEPsAKE 2 (NCT03671148) phase 3 trials, risankizumab demonstrated greater efficacy compared with placebo in patients with active psoriatic arthritis (PsA). This post hoc integrated analysis evaluated achieving the following efficacy outcomes at weeks 24 and 52 by baseline demographics and clinical characteristics: ≥20%/50%/70% improvement in American College of Rheumatology response criteria (ACR20/50/70), ≥90% improvement in Psoriasis Area and Severity Index, minimal disease activity status, Low Disease Activity status (Disease Activity in Psoriatic Arthritis), and minimal clinically important difference in pain. Baseline demographics and clinical characteristics were similar between risankizumab (n = 707) and placebo (n = 700) groups. Numerically higher ACR20 response rates at week 24 (primary endpoint) were observed among the risankizumab (46.3%-60.1%) vs. placebo (15.5%-36.2%) cohorts, regardless of subgroups. At week 52, consistent proportions of patients randomized to risankizumab achieved ACR20 (48.6%-75.8%) while those initially randomized to placebo and switched to risankizumab experienced an improvement from week 24 (43.7%-63.9%), regardless of subgroups. Similar trends were observed for other efficacy measures assessing rigorous skin response criteria, composite measures of overall disease activity, and PsA-related symptoms. Risankizumab treatment was efficacious among patients with varying demographic and psoriatic disease characteristics through 52 weeks.

Venous thromboembolism risk is lower in patients with atopic dermatitis than other immune-mediated inflammatory diseases: A retrospective, observational, comparative cohort study using US claims data

BACKGROUND

Certain immune-mediated inflammatory diseases (IMIDs) may increase patients' risk for venous thromboembolisms (VTEs), yet how atopic dermatitis (AD) influences VTE risk remains unclear.

OBJECTIVE

Describe VTE incidence in patients with AD compared with other IMIDs and unaffected, AD-matched controls.

METHODS

This retrospective, observational, comparative cohort study used Optum Clinformatics United States claims data (2010-2019) of adults with AD, rheumatoid arthritis (RA), Crohn's disease (CD), ulcerative colitis (UC), psoriasis (PsO), psoriatic arthritis (PsA), or ankylosing spondylitis (AS). Unaffected control patients were matched 1:1 with patients with AD.

RESULTS

Of 2,061,222 patients with IMIDs, 1,098,633 had AD. Patients with AD had a higher VTE incidence (95% CI) than did unaffected, AD-matched controls (0.73 [0.72-0.74] versus 0.59 [0.58-0.60] cases/100 person-years). When controlling for baseline VTE risk factors, however, AD was not associated with increased VTE risk (HR 0.96 [0.90-1.02]). VTE risk was lower in patients with AD versus RA, UC, CD, AS, or PsA; VTE risk was similar to patients with PsO.

LIMITATIONS

Disease activity and severity were not accounted for.

CONCLUSION

AD did not increase VTE risk when accounting for underlying risk factors. AD was associated with lower VTE risk compared with several rheumatologic and gastrointestinal IMIDs.

Bimekizumab safety in moderate to severe plaque psoriasis: Rates of hepatic events and changes in liver parameters over 2 years in randomized phase 3/3b trials

BACKGROUND

Patients with psoriasis are at increased risk of liver function abnormalities.

OBJECTIVE

Explore rates of hepatic treatment-emergent adverse events (TEAEs) and changes in liver parameters in bimekizumab-treated patients with psoriasis.

METHODS

Data are reported from five phase 3/3b trials over 2 years. Hepatic TEAEs, laboratory elevations in alanine aminotransferase (ALT) or aspartate aminotransferase (AST), and changes in clinical markers of liver fibrosis (Fibrosis-4 [FIB-4] Index and AST to Platelet Ratio Index [APRI]) are reported. TEAEs are presented using exposure-adjusted incidence rates (EAIRs) per 100 patient-years (PY).

RESULTS

2,186 patients received ≥1 bimekizumab dose. Over 2 years, the EAIR of hepatic TEAEs was 3.5/100 PY and did not increase from first to second year. 2-year EAIRs of ALT/AST elevations >3x and >5x ULN were 2.3 and 0.6/100 PY; rates were similar to placebo, adalimumab, secukinumab, and ustekinumab during controlled study periods. FIB-4 and APRI scores did not increase through 2 years, regardless of fibrosis risk at baseline.

LIMITATIONS

Obesity, diabetes, dyslipidemia, chronic alcohol consumption, and medication changes are confounding factors for hepatic dysfunction.

CONCLUSION

Rates of hepatic adverse events with bimekizumab were consistent through 2 years; incidences of transaminase elevations were similar to comparators during phase 3/3b controlled study periods.

TYK2: an emerging therapeutic target in rheumatic disease

Tyrosine kinase 2 (TYK2) is a member of the JAK kinase family of intracellular signalling molecules. By participating in signalling pathways downstream of type I interferons, IL-12, IL-23 and IL-10, TYK2 elicits a distinct set of immune events to JAK1, JAK2 and JAK3. TYK2 polymorphisms have been associated with susceptibility to various rheumatic diseases including systemic lupus erythematosus and dermatomyositis. In vitro and animal studies substantiate these findings, highlighting a role for TYK2 in diseases currently managed by antagonists of cytokines that signal through TYK2. Various inhibitors of TYK2 have now been studied in human disease, and one of these inhibitors, deucravacitinib, has now been approved for the treatment of psoriasis. Phase II trials of deucravacitinib have also reported positive results in the treatment of psoriatic arthritis and systemic lupus erythematosus, with a preliminary safety profile that seems to differ from that of the JAK1, JAK2 and JAK3 inhibitors. Two other inhibitors of TYK2, brepocitinib and ropsacitinib, are also in earlier stages of clinical trials. Overall, TYK2 inhibitors hold promise for the treatment of a distinct spectrum of autoimmune diseases and could potentially have a safety profile that differs from other JAK inhibitors.

Deucravacitinib, a selective, allosteric tyrosine kinase 2 inhibitor, in scalp psoriasis: A subset analysis of two phase 3 randomized trials in plaque psoriasis

BACKGROUND

Scalp involvement in plaque psoriasis is challenging to treat.

OBJECTIVE

To evaluate the efficacy and safety of deucravacitinib (DEUC) in scalp psoriasis.

METHODS

POETYK PSO-1 and PSO-2 were global phase 3, 52-week, double-blinded trials in adults with moderate to severe psoriasis. Patients were randomized 1:2:1 to oral placebo, DEUC 6 mg once daily, or apremilast 30 mg twice daily. This pooled secondary analysis evaluated scalp-specific Physician Global Assessment score of 0 or 1 (0/1), ≥90% improvement from baseline in Psoriasis Scalp Severity Index, and change from baseline in Psoriasis Scalp Severity Index. Adverse events were evaluated through week 16.

RESULTS

Overall, 1084 patients with moderate to severe scalp psoriasis at baseline were included. At week 16, response rates were greater with DEUC versus placebo or apremilast for scalp-specific Physician Global Assessment 0/1 (64.0% vs 17.3% vs 37.7%; P < .0001), ≥90% improvement from baseline in Psoriasis Scalp Severity Index (50.6% vs 10.5% vs 26.1%; P < .0001), and change from baseline in Psoriasis Scalp Severity Index. Responses were maintained through 52 weeks with continuous DEUC. Safety was consistent with the entire study population.

LIMITATIONS

Lack of data in milder scalp psoriasis.

CONCLUSION

DEUC was significantly more efficacious than placebo or apremilast in improving moderate to severe scalp psoriasis and was well tolerated.

Mental health outcomes in patients with moderate to severe psoriasis treated with bimekizumab: Analysis of phase 2/3 randomized trials

BACKGROUND

Patients with psoriasis have increased risk of suicidal ideation and behavior (SIB) and depression. Bimekizumab, a biologic that inhibits interleukin (IL)-17A and IL-17F, received Food and Drug Administration approval in 2023 for moderate to severe plaque psoriasis, following 2021 European Medicines Agency approval.

OBJECTIVE

To report SIB and depression in patients with moderate to severe psoriasis treated in bimekizumab clinical trials.

METHODS

Mental health changes, including neuropsychiatric events, were actively monitored across 9 bimekizumab clinical trials in psoriasis phase 2/3 trials. The patient-reported electronic Columbia-Suicide Severity Rating Scale (measuring SIB) and Patient Health Questionnaire-9 (measuring depression) were administered, monitored by an independent Neuropsychiatric Adjudication Committee.

RESULTS

Throughout 7166 patient-years (PY) of bimekizumab exposure, the adjudicated SIB rate was 0.13/100PY; SIB ranges for the general psoriasis population and patients receiving anti-IL-17A/anti-IL-23 therapies are 0.09 to 0.54/100PY and 0.09 to 0.19/100PY, respectively. At week 16, 92.9% vs 81.1% of bimekizumab- vs placebo-treated patients had no/minimal depression. Newonset positive electronic Columbia-Suicide Severity Rating Scale responses and mean Patient Health Questionnaire-9 scores were low for bimekizumab-treated patients.

LIMITATIONS

Patient exclusion for significant/severe prespecified SIB/depression history.

CONCLUSION

The long-term adjudicated SIB rate with bimekizumab was low and within ranges reported in the general psoriasis patient population and psoriasis patients treated with anti-IL-17A/anti-IL-23 biologics. Screening/monitoring questionnaires reported low SIB and depression levels.

Efficacy and safety of apremilast in patients with moderate-to-severe genital psoriasis: Results from DISCREET, a phase 3 randomized, double-blind, placebo-controlled trial

BACKGROUND

Genital psoriasis can be stigmatizing, is highly prevalent among patients with psoriasis, and has limited treatment options. Apremilast is a unique oral immunomodulating phosphodiesterase 4 inhibitor approved for psoriasis treatment.

OBJECTIVE

To assess the efficacy and safety of apremilast 30 mg twice daily in patients with genital psoriasis.

METHODS

DISCREET, a phase 3, placebo-controlled trial (NCT03777436), randomized patients with moderate-to-severe genital psoriasis (stratified by affected body surface area <10% or ≥10%) to apremilast or placebo for a 16-week period, followed by an apremilast extension period. Week 16 results are presented.

RESULTS

Patients were randomized to apremilast (n = 143) or placebo (n = 146). At Week 16, 39.6% and 19.5% of apremilast and placebo patients, respectively, achieved a modified static Physician Global Assessment of Genitalia response (primary endpoint; score of 0/1, ≥2-point reduction); treatment difference was significant (20.1%, P = .0003). Improvements in genital signs and symptoms, skin involvement, and quality of life were observed. Common treatment-emergent adverse events were diarrhea, headache, nausea, and nasopharyngitis.

LIMITATIONS

Lack of active-comparator.

CONCLUSIONS

Apremilast demonstrated statistically and clinically meaningful genital Physician Global Assessment responses and improvement of signs, symptoms, severity, and quality of life in this first randomized, controlled study of an oral systemic treatment in patients with genital psoriasis.

Improvements in Patient-Reported Outcomes Through Six Months of Guselkumab Treatment in Patients With Active Psoriatic Arthritis: Real-World Data From the CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry

OBJECTIVE

Evaluate patient-reported outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry.

METHODS

This analysis includes registry participants who initiated and persisted with on-label guselkumab (after US Food and Drug Administration approval for PsA; 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (On-Label Persisters). Among patients not meeting response criteria at baseline, responses at 6 months were determined for patient-reported outcomes, including patient-reported pain (0-100 mm visual analog scale), patient global assessment of arthritis + psoriasis (PtGA; 0-100 visual analog scale), and Health Assessment Questionnaire-Disability Index (HAQ-DI; 0-3). Unadjusted, nominal P values were calculated via single-proportion, one-sided test (H0 = 0%; α = 0.05).

RESULTS

Of 90 On-Label Persisters, most had treatment-resistant PsA (92.2% and 73.3% previously received ≥1 and ≥2 biologic/targeted synthetic disease-modifying antirheumatic drugs, respectively), with mean (SD) baseline patient-reported pain, PtGA, and HAQ-DI scores of 57.0 (24.6), 50.3 (24.4), and 0.9 (0.6), respectively. Among those with patient-reported pain and PtGA scores of at least 15 at baseline, 40.2% (33/82) and 46.8% (36/77), respectively, achieved at least 15-mm reductions at 6 months; among those with HAQ-DI scores of at least 0.35 and more than 0.5 at baseline, respectively, 30.4% (21/69) achieved improvements of at least 0.35 and 10.3% (6/58) achieved scores of 0.5 or lower at 6 months (all nominal P < 0.001).

CONCLUSION

Pain and physical function are important contributors to health-related quality of life. In this real-world population of patients with treatment-resistant PsA and 6 months of persistent guselkumab treatment, clinically meaningful improvements in pain and physical function were achieved by approximately 40% and 30% of patients, respectively.

Bimekizumab treatment in patients with active psoriatic arthritis and prior inadequate response to tumour necrosis factor inhibitors: 52-week safety and efficacy from the phase III BE COMPLETE study and its open-label extension BE VITAL

OBJECTIVES

To assess 52-week safety and efficacy of bimekizumab in patients with active psoriatic arthritis (PsA) and prior inadequate response/intolerance to tumour necrosis factor inhibitors.

METHODS

Patients completing the 16-week phase III double-blind, placebo-controlled BE COMPLETE (NCT03896581) study entered the open-label extension, BE VITAL (NCT04009499). All patients in BE VITAL received 160 mg bimekizumab every 4 weeks. Safety and efficacy are reported to week 52.

RESULTS

A total of 347/400 (86.8%) patients completed week 52. To week 52, the exposure-adjusted incidence rate/100 patient-years for ≥1 treatment-emergent adverse event (TEAE) was 126.0, and was 7.0 for serious TEAEs. The most frequent TEAEs were SARS-CoV-2 (COVID-19), oral candidiasis, nasopharyngitis and urinary tract infection. All fungal infections were mild or moderate in severity and localised; two patients discontinued the study due to oral candidiasis. No cases of active tuberculosis, uveitis or inflammatory bowel disease were reported. One sudden death occurred. Sustained efficacy was observed with bimekizumab from week 16 to ‍52 across clinical and patient-reported outcomes. At week 52, 51.7% bimekizumab-randomised and 40.6% placebo/bimekizumab patients (receiving bimekizumab from week 16 to 52) had ≥50% improvement in the American College of Rheumatology criteria. Complete skin clearance (Psoriasis Area and Severity Index 100) was achieved by 65.9% bimekizumab and 60.2% placebo/bimekizumab patients at week 52. Minimal disease activity was achieved by 47.2% bimekizumab and 33.1% placebo/bimekizumab patients at week 52.

CONCLUSIONS

Bimekizumab demonstrated a safety profile consistent with previous reports; no new safety signals were identified. Sustained efficacy was observed from week 16 to 52.

Long-term safety of Ixekizumab in adults with psoriasis, psoriatic arthritis, or axial spondyloarthritis: a post-hoc analysis of final safety data from 25 randomized clinical trials

BACKGROUND

We report long-term, end-of-study program safety outcomes from 25 randomized clinical trials (RCTs) in adult patients with psoriasis (PsO), psoriatic arthritis (PsA), or axial spondyloarthritis (axSpA) [including ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA)] who received ≥ 1 dose of Ixekizumab (IXE) over 5 years (PsO) or up to 3 years (PsA, axSpA).

METHODS

This integrated safety analysis consists of data from patients who received any dose of IXE, across 25 RCTs (17 PsO, 4 PsA, 4 axSpA). Rates of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs) and selected adverse events (AEs) of interest were analyzed for all pooled studies by years of therapy and overall, through March 2022. Results were reported as exposure-adjusted incidence rates (IRs) per 100 patient-years (PY) overall and at successive year intervals.

RESULTS

Six thousand eight hundred ninety two adult patients with PsO, 1401 with PsA, and 932 with axSpA (including AS and nr-axSpA), with a cumulative IXE exposure of 22,371.1 PY were included. The most commonly reported TEAE across indications was nasopharyngitis (IRs per 100 PY: 8.8 (PsO), 9.0 (PsA), 8.4 (axSpA)). SAEs were reported by 969 patients with PsO (IR 5.4), 134 patients with PsA (IR 6.0), and 101 patients with axSpA (IR 4.8). Forty-five deaths were reported (PsO, n = 36, IR 0.2; PsA, n = 6, IR 0.3; axSpA, n = 3, IR 0.1). TEAEs did not increase during IXE exposure: IRs per 100 PY, PsO: 88.9 to 63.2 (year 0-1 to 4-5), PsA: 87 to 67.3 (year 0-1 to 2-3), axSpA: 82.1 to 55.4 (year 0-1 to >  = 2). IRs per 100 PY of discontinuation from IXE due to AE were 2.9 (PsO), 5.1 (PsA), and 3.1 (axSpA). IRs per 100 PY of injection site reactions were 5.9 (PsO), 11.6 (PsA) and 7.4 (axSpA); Candida: 1.9 (PsO), 2.0 (PsA), and 1.2 (axSpA); depression, major adverse cerebro-cardiovascular events and malignancies: ≤ 1.6 across all indications. Adjudicated IRs per 100 PY of inflammatory bowel disease were ≤ 0.8 across indications (0.1 [PsO]; 0.1 [PsA]; 0.8 [axSpA]).

CONCLUSIONS

In this integrated safety analysis, consisting of over 22,000 PY of exposure, the long-term safety profile of IXE was found to be consistent with previous, earlier reports, with no new safety signals identified.

Association of the clinical components in the distal interphalangeal joint synovio-entheseal complex and subsequent response to ixekizumab or adalimumab in psoriatic arthritis

OBJECTIVES

To assess the frequency of simultaneous distal interphalangeal (DIP) joint disease and adjacent nail psoriasis (finger unit) among patients with psoriatic arthritis (PsA) and compare the efficacy of the interleukin (IL)-17A antagonist ixekizumab (IXE) and the tumour necrosis factor (TNF)-α inhibitor adalimumab (ADA).

METHODS

This post hoc analysis evaluated the simultaneous occurrence of DIP joint involvement (tenderness and/or swelling) and adjacent nail psoriasis among patients with PsA from the SPIRIT-H2H (NCT03151551) trial comparing IXE to ADA. Among patients with simultaneous DIP joint involvement and adjacent nail psoriasis in ≥ 1 digit at baseline, treatment effects were assessed through week 52 for each affected finger unit; 'finger unit' defines the connected DIP joint and adjacent nail of an individual digit.

RESULTS

A total of 354 patients had simultaneous DIP joint involvement and adjacent nail psoriasis in ≥ 1 finger unit at baseline. Among them, 1309 (IXE = 639, ADA = 670) finger units had baseline DIP joint tenderness and/or swelling and adjacent nail psoriasis. Proportions of affected finger units achieving complete resolution were significantly higher with IXE vs ADA as early as week 12 (38.8% vs 28.4%, p< 0.0001) and at all post-baseline assessments through week 52 (64.9% vs 57.5%, p= 0.0055).

CONCLUSIONS

In this study cohort, patients with DIP joint involvement almost always had adjacent nail psoriasis. Greater resolution of DIP joint tenderness, swelling, and adjacent nail psoriasis was achieved at all timepoints over 52 weeks through targeting IL-17A with IXE than TNF-α with ADA, which is noteworthy given prior comparable musculoskeletal outcomes for both drug classes.

The Efficacy and Safety of Bimekizumab for Plaque Psoriasis: An Expert Consensus Panel

INTRODUCTION

Psoriasis is a chronic inflammatory condition affecting the skin, joints, and several other organ systems with significant disease burden. Bimekizumab is the first monoclonal antibody targeting both interleukin (IL)-17A and interleukin-17F and has demonstrated efficacy for treating moderate to severe psoriasis. Limited guidelines exist for incorporating this drug into clinical practice. The purpose of this study was for a panel of experts in psoriasis management to synthesize current literature and provide consensus statements with guidance on use of bimekizumab.

METHODS

A comprehensive literature search of PubMed, Scopus, and Google Scholar was completed for English-language original research articles on the use of bimekizumab for moderate to severe psoriasis and psoriatic arthritis. A panel of nine dermatologists with significant expertise in treatment of psoriasis gathered to review the articles and create consensus statements on this new medication. A modified Delphi process was used to approve each statement and a strength of recommendation was assigned using Strength of Recommendation Taxonomy criteria.

RESULTS

The literature search produced 102 articles that met criteria. A thorough screening of the studies for relevance to the research question resulted in 19 articles. These were distributed to all panelists for review prior to a roundtable discussion. The panel unanimously voted to adopt 14 consensus statements and recommendations, 12 of which were given a strength of "A", one of which was given a strength of "B", and one of which was given a strength of "C".

CONCLUSION

Bimekizumab results in rapid and long-lasting clinical improvement for patients with moderate to severe plaque psoriasis and psoriatic arthritis. It has demonstrated superior efficacy when compared to several other biologics. The safety profile is consistent with other biologics, except for an increased incidence of oropharyngeal candidiasis.

A Case Series of TNF Inhibitor-Induced Psoriasis Successfully Treated With Upadacitinib

Tumor necrosis factor-alpha inhibitors (TNF-i) are commonly used to treat immune-mediated diseases such as psoriasis, psoriatic arthritis (PsA), inflammatory bowel disease (IBD), spondyloarthritis (SpA) and rheumatoid arthritis (RA). However, paradoxical psoriasis induced by TNF-i has been described and is not uncommon, particularly with infliximab and etanercept. The presentation of TNF-i-induced psoriasis is most commonly plaque or palmoplantar morphology. Optimal treatment strategies for recalcitrant psoriatic disease are not well understood. In this case series, we report three patients with TNF-i-induced psoriasis who were treated with upadacitinib and experienced complete resolution of their psoriatic eruptions. The efficacy of Janus kinase inhibitors (JAK-i) is possibly explained by mechanisms involving uncontrolled production of type 1 IFNs as well as increases in IL-23 and T-helper 17 cells upstream of relevant JAK/STAT pathways. We also offer a proposed treatment algorithm that includes the use of JAK-i as a promising management option in patients with recalcitrant disease. However, larger studies are needed to confirm the efficacy and safety of JAK-i in this patient population. J Drugs Dermatol. 2024;23(2): doi:10.36849/JDD.7645.

A New Tool to Improve Communication Between Hidradenitis Suppurativa Patients and Health Care Providers

BACKGROUND

Hidradenitis suppurativa (HS) patients tend to experience diagnosis delay, misdiagnosis, and embarrassment due to their condition. To address these issues, the International Dermatology Outcome Measure (IDEOM) HS Workgroup collaborated with patients to modify an existing Novartis questionnaire to better suit the needs of HS patients. This quality improvement project aimed to use the resulting Shine a Light on HS as Modified by the IDEOM HS Workgroup Questionnaire to enhance communication between HS patients and providers, improve clinical experience for HS patients, and gather relevant demographic data.

METHOD

Patients with HS presenting to Mount Sinai Union Square over a 9-month long period were invited to complete the Shine a Light on HS as Modified by the IDEOM HS Workgroup Questionnaire before seeing their providers. After the visit, patients rated their overall clinical experience and the helpfulness of the survey on a 5-point scale.

RESULTS

The analysis cohort (n=30) consisted of a racially and ethnically diverse patient population. On a scale of 0-4, the mean helpfulness rating was 3.1 (SD=1), and the mean clinical experience rating was 3.5 (SD=0.78). There was a positive correlation between survey helpfulness and overall clinical experience and a moderately strong relationship by linear regression analysis (r=0.73, R2=0.53). 80% reported frequent flares, 54% reported >10 years of symptoms, and the most commonly affected areas were the axillae, gluteal cleft, groin, and inguinocrural folds. The mean pain rating was 8 out of 10 (SD=2.55, Var=6.5). The majority of patients reported scars, tunnels, open wounds, ER/Urgent Care visits, inflammatory skin symptoms, and systemic symptoms. 39% had a positive HS family history. Biologics were the least common previous treatment reported (43%). Emotional burden was reported by nearly all patients, and comorbidities included depression, heart disease, arthritis, polycystic ovary syndrome (PCOS), diabetes, and irritable bowel disease (IBD).

CONCLUSION

The Shine a Light on HS as Modified by the IDEOM HS Workgroup Questionnaire was successful in improving HS patient-provider conversations, enhancing the overall clinical experience for HS patients, and collecting insightful demographic data. Healthcare providers should consider incorporating the questionnaire as part of their routine care for HS to enhance clinical discussion and improve outcomes for patients. J Drugs Dermatol. 2024;23(2):105-109.   doi:10.36849/JDD.7624.

A clinical review of structural damage in psoriatic arthritis for dermatologists: From pathogenesis to ongoing controversies

Psoriatic arthritis (PsA) is a chronic inflammatory disease that often goes unrecognized in patients with psoriasis. As a result, patients may develop significant structural damage before diagnosis and initiation of adequate treatment. Dermatologists are in an unique position to identify early signs and symptoms of PsA. Here, we briefly review the pathogenesis of PsA, differences in PsA presentation within real-world dermatology practice versus rheumatology clinical trials, and imaging modalities that can be used to assess structural damage. We then discuss several ongoing controversies related to prediction, assessment, and treatment of PsA-related structural damage. Debated questions include the following: (1) Does subclinical enthesitis predict progression from psoriasis to PsA?, (2) Does methotrexate inhibit progression of structural damage?, (3) Does structural damage correlate with clinical disease activity?, and (4) Can progression from psoriasis to PsA be prevented? Evidence presented herein suggests that dermatologists, together with rheumatologists, can play important roles in the early diagnosis and treatment of PsA, thereby potentially preventing irreversible structural damage.

Patient-Reported Outcome Measures for Health-Related Quality of Life in Patients With Psoriasis: A Systematic Review

Importance

Multiple patient-reported outcome measures (PROMs) for health-related quality of life (HRQL) exist for patients with psoriasis. Evidence for the content validity and other measurement properties of these PROMs is critical to determine which HRQL PROMs could be recommended for use.

Objective

To systematically review the validity of HRQL-focused PROMs used in patients with psoriasis.

Evidence Review

Using PubMed and Embase, full-text articles published in English or Spanish on development or validation studies for psoriasis-specific, dermatology-specific, or generic HRQL PROMs were included. Development studies included original development studies, even if not studied in psoriasis patients per Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) recommendations. If a study included multiple diagnoses, more than 50% of patients had to have psoriasis or psoriasis-specific subgroup analyses available. Data extraction and analysis followed the COSMIN guidelines. Two independent reviewers extracted and analyzed the data, including PROM characteristics, quality of measurement properties (structural validity, internal consistency, cross-cultural validity, reliability, measurement error, criterion validity, construct validity, and responsiveness), and level of evidence. PROMs were classified into 3 levels of recommendations: (1) PROM recommended for use; (2) PROM requires further validation; and (3) PROM not recommended for use.

Findings

Overall, 97 articles were identified for extraction. This included 19 psoriasis-specific, 8 skin-specific, and 6 generic PROMs. According to COSMIN standards, most measures identified received a B recommendation for use, indicating their potential but requiring further validation. Only the Rasch reduced version of the Impact of Psoriasis Questionnaire (IPSO-11 Rasch) received an A recommendation for use given that it had sufficient content validity, structural validity, and internal consistency.

Conclusions and Relevance

This study identified a significant lack of information concerning the quality of HRQL measures in psoriasis. This gap in knowledge can be attributed to the fact that traditional measures were developed using validation criteria that differ from the current standards in use. Consequently, additional validation studies in accordance with contemporary standards will be useful in aiding researchers and clinicians in determining the most suitable measure for assessing HRQL in patients with psoriasis.

Comparative efficacy and safety of bimekizumab in psoriatic arthritis: a systematic literature review and network meta-analysis

OBJECTIVES

To understand the relative efficacy and safety of bimekizumab, a selective inhibitor of interleukin-17F in addition to IL-17A, vs other biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) for psoriatic arthritis (PsA) using network meta-analysis (NMA).

METHODS

A systematic literature review (most recent update conducted on 01 January 2023) identified randomised controlled trials (RCTs) of b/tsDMARDs in PsA. Bayesian NMAs were conducted for efficacy outcomes at Weeks 12-24 for b/tsDMARD-naïve and tumour necrosis factor inhibitor (TNFi) -experienced (exp) patients. Safety at Weeks 12-24 was analysed in a mixed population. Odds ratios (ORs) and differences of mean change with the associated 95% credible interval (CrI) were calculated for the best-fitting models, and the surface under the cumulative ranking curve (SUCRA) values were calculated to determine relative rank.

RESULTS

The NMA included 41 RCTs for 22 b/tsDMARDs. For minimal disease activity (MDA), bimekizumab ranked 1st in b/tsDMARD-naïve patients and 2nd in TNFi-exp patients. In b/tsDMARD-naïve patients, bimekizumab ranked 6th, 5th, and 3rd for American College of Rheumatology response (ACR)20/50/70, respectively. In TNFi-experienced patients, bimekizumab ranked 1st, 2nd, and 1st for ACR20/50/70, respectively. For Psoriasis Area and Severity Index [PASI]90/100, bimekizumab ranked 2nd and 1st in b/tsDMARD-naïve patients, respectively, and 1st and 2nd in TNFi-exp patients, respectively. Bimekizumab was comparable to b/tsDMARDs for serious adverse events.

CONCLUSION

Bimekizumab ranked favourably among b/tsDMARDs for efficacy on joint, skin, and MDA outcomes, and showed comparable safety, suggesting it may be a beneficial treatment option for patients with PsA.

Six-Month Persistence and Multi-domain Effectiveness of Guselkumab in Adults with Psoriatic Arthritis: Real-World Data from the CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry

INTRODUCTION

The aim of this work is to evaluate treatment persistence and clinical outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry.

METHODS

Participants with PsA who initiated and persisted with on-label guselkumab use post-Food and Drug Administration (FDA) approval for active PsA (7/13/2020; subcutaneous 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (occurring through 3/31/2023) comprised the primary analysis population (On-Label Persisters). Hierarchical, multiplicity-controlled primary and secondary outcomes were mean (95% confidence interval) changes from baseline at 6 months in clinical Disease Activity Index for PsA (cDAPSA; primary), Physician Global Assessment (PGA) of arthritis and psoriasis (visual analog scale [VAS] 0-100), patient-reported pain (VAS 0-100), and percent body surface area with psoriasis (%BSA). Paired t tests determined changes that were statistically significantly different from 0 (α = 0.05).

RESULTS

Among 114 patients who initiated on-label guselkumab and had eligible baseline and 6-month visits, 90 (78.9%) had persistent use. Among these On-Label Persisters at baseline, mean duration of PsA symptoms = 13.6 years; mean cDAPSA, PGA, and patient-reported pain = 22.0, 42.3, and 57.0, respectively; 94.4% had a history of psoriasis (mean BSA 7.6%); and 18.9% and 73.3%, respectively, previously received 1 or ≥ 2 biologic/targeted synthetic disease-modifying antirheumatic drugs. The mean change (improvement) in cDAPSA was - 5.4 (- 8.5, - 2.3; p < 0.001) at 6 months. Significant mean improvements in PGA (- 19.0 [- 24.2, - 13.8]), patient-reported pain (- 9.1 [- 14.4, - 3.8]), and %BSA (- 5.1 [- 7.6, - 2.7]) were also observed (all p < 0.001).

CONCLUSIONS

In this real-world PsA population, generally characterized by longstanding, treatment-resistant, active disease at baseline, persistent guselkumab use in nearly 80% of patients with on-label use was accompanied by significant improvements in joint and skin symptoms and patient-reported pain at 6 months. These registry data support results from randomized clinical trials demonstrating the efficacy of guselkumab in improving PsA signs and symptoms.

Successful Treatment of Keloids and Hypertrophic Scars With Systemic and Intralesional Dupilumab

Keloids and hypertrophic scars negatively impact the quality of life for millions of people in the world. Unfortunately, though many thera-peutic approaches are used to treat scars, they are often limited in efficacy with high rates of recurrence. Lately, a better understanding of the immune dysregulation of several dermatologic conditions has led to the emergence of multiple cytokine-targeted therapies for numerous conditions. Several studies have implicated T helper 2 (Th2) immune dysregulation in the development of scars and keloids, with interleukins (IL)-4 and -13 identified as pro-fibrotic mediators. Dupilumab is an IL-4 receptor alpha antagonist that inhibits the ex-pression of both IL-4 and -13. Herein, we describe a 44-year-old woman who developed numerous disfiguring hypertrophic scars and keloids after suffering from a severe herpes zoster infection. Given the number of scars, intralesional corticosteroid injections were not feasible. Therefore, treatment with systemic dupilumab was initiated. Many scars flattened, several even developing a cigarette-paper-like texture due to rapid involution. The largest and most recalcitrant keloid was further treated with intralesional dupliumab injec-tions every 2 weeks with an even more dramatic improvement noted in 2 months. To our knowledge, this is the first report of treating multiple keloids and hypertrophic scars with both systemic and intralesional dupilumab. Dermatologists may want to consider treating keloids that cover a large area with systemic dupilumab, a therapy with an established, reassuring safety profile. The most recalcitrant areas may further benefit from concentrating dupilumab by intralesional delivery. J Drugs Dermatol. 2023;22(12):1220-1222.  doi:10.36849/JDD.6385.

Dupilumab significantly improves sleep in adults with atopic dermatitis: results from the 12-week placebo-controlled period of the 24-week phase IV randomized double-blinded placebo-controlled DUPISTAD study

BACKGROUND

Sleep disturbance is a prominent symptom of atopic dermatitis (AD) and can result in insomnia, daytime fatigue, drowsiness, reduced productivity and impaired quality of life (QoL).

OBJECTIVES

The Dupilumab Effect on Sleep in AD Patients (DUPISTAD) phase IV randomized double-blinded placebo-controlled study evaluated the impact of dupilumab treatment on sleep and other patient- and physician-reported outcomes.

METHODS

Adults with moderate-to-severe AD were randomized 2 : 1 to dupilumab 300 mg once every 2 weeks (q2w) or placebo for 12 weeks; concomitant topical corticosteroids were permitted. Patients subsequently entered an open-label phase and received dupilumab 300 mg q2w for a further 12 weeks. The primary endpoint was the percentage change in sleep quality from baseline to week 12, assessed using a novel numeric rating scale (NRS). Secondary and exploratory endpoints included percentage change in peak pruritus NRS (PP NRS), change in SCORing Atopic Dermatitis (SCORAD), SCORAD sleep visual analogue scale (VAS), Eczema Area and Severity Index, Patient-Reported Outcomes Measurement Information System (PROMIS) sleep-related impairment T-score and the Epworth Sleepiness Scale. Sleep diary and wrist actigraphy measurements were recorded throughout the study.

RESULTS

In total, 127 patients received dupilumab and 61 patients received placebo. Demographic and baseline disease characteristics were balanced between groups. Sleep quality NRS significantly improved in patients treated with dupilumab by week 12 vs. placebo [least squares mean of the difference (LSMD) -15.5%, P < 0.001]. PP NRS (LSMD -27.9%, P < 0.001), SCORAD (LSMD -15.1, P < 0.001), SCORAD sleep VAS (LSMD -2.1, P < 0.001) and PROMIS T-score (LSMD -3.6, P < 0.001) were also significantly improved at week 12 with dupilumab vs. placebo. The overall percentage of patients reporting treatment-emergent adverse events was lower in the dupilumab group (56.7%) than in the placebo group (67.2%).

CONCLUSIONS

Dupilumab significantly improved sleep quality and perception of sleep continuity, itch, metrics of AD severity and QoL in adults with moderate-to-severe AD, with an acceptable safety profile compared with placebo.

Prevalence of Musculoskeletal Symptoms in Patients with Psoriasis and Predictors Associated with the Development of Psoriatic Arthritis: Retrospective Analysis of a US Claims Database

INTRODUCTION

Psoriasis (PsO) is associated with the development of psoriatic arthritis (PsA). Patients with PsO often experience pre-PsA musculoskeletal (MSK) symptoms, leading to potential structural damage and substantial disease burden with impact on function. The objective of this study is to describe prevalence rates and evidence of MSK symptoms, including incidence of comorbid PsA diagnosis, in patients newly diagnosed with PsO and identify factors associated with PsA diagnosis.

METHODS

This retrospective analysis included administrative claims from the Optum Research Database for adult patients with a new PsO diagnosis between January 2008 and February 2019. Eligible patients had ≥ 2 claims for PsO on unique dates, were aged ≥ 18 years at the date of the first claim with a diagnosis of PsO (index date), and had continuous enrollment with medical and pharmacy coverage for 12 months before (baseline period) and ≥ 12 months following the index date. Primary outcomes were incidence of comorbid PsA diagnosis, prevalence of MSK symptoms other than PsA, and evidence of MSK symptoms collected at baseline and assessed in 12-month intervals through 60 months.

RESULTS

Of the 116,203 patients with newly diagnosed PsO, 110,118 were without baseline comorbid PsA. High prevalence rates of MSK symptoms among patients with only PsO were seen at baseline (47.1%), 12 months (48.2%), and 60 months (82.1%). Patient age, baseline MSK symptoms, and baseline MSK symptom-related healthcare utilization were associated with increased hazard of a PsA diagnosis.

CONCLUSION

Increased prevalence rates of MSK symptoms and burden are experienced by patients newly diagnosed with PsO through 60 months of follow-up. Several baseline factors were associated with increased risk of PsA diagnosis.

Screening and Referral Strategies for the Early Recognition of Psoriatic Arthritis Among Patients With Psoriasis: Results of a GRAPPA Survey

OBJECTIVE

This study aimed to explore the experiences of dermatologists and rheumatologists in the early recognition of psoriatic arthritis (PsA) and to identify potential improvements to the current shared-care model.

METHODS

A 24-question survey addressing referral strategies was constructed by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) project steering committee and sent to all members (n = 927). Questions addressed the use of screening tools, frequency of PsA in patients with psoriasis, therapeutic decision making, and suggestions for earlier PsA recognition and current unmet needs.

RESULTS

There were 149 respondents (16.1% response rate), which included 113 rheumatologists from 37 countries and 26 dermatologists from 16 countries. Of the dermatologists, 81% use PsA-specific screening instruments. Conversely, rheumatologists reported that only 26.8% of patients referred to them from all sources had been assessed with screening tools. Although dermatologists reported that a mean of 67% of suspected PsA cases were confirmed, rheumatologists reported a mean of 47.9% of confirmed cases. Both specialties reported similar views regarding optimization of the diagnostic process and indicated that the best approach involved combining patient-reported (ie, screening tools) and physician-confirmed findings. Moreover, both specialties identified the education of primary care physicians (PCPs) and dermatologists as the greatest priority to improve PsA screening.

CONCLUSION

The survey indicated the current unmet needs in the early recognition of PsA. Important areas to address include improving the use of screening instruments, increasing the education of community-based dermatologists and PCPs, and using a combination of patient-reported and physician-confirmed findings in the screening approach.

Interleukin (IL)-17 Versus IL-23 Inhibitors: Which Is Better to Treat Patients With Moderate-to-Severe Psoriasis and Mild Psoriatic Arthritis in Dermatology Clinics?

Interleukin (IL)-17 and IL-23 inhibitors are both approved for the treatment of moderate-to-severe plaque psoriasis (PsO), as well as psoriatic arthritis (PsA). In the absence of head-to-head studies, it is not clear which agent is better suited to treat patients with moderate-to-severe PsO and mild PsA. During the 2022 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) conference, Dr. April Armstrong and Dr. Joseph Merola debated which of these 2 biologic classes should be used in this patient population. Armstrong argued in favor of IL-17 inhibition, whereas Merola presented reasons for IL-23 inhibition. An overview of their main arguments is described in this manuscript.

Proceedings of the GRAPPA 2022 Executive Retreat

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) leadership congregated for a strategic planning meeting before the 2022 GRAPPA annual meeting in New York, USA. Meeting aims were to review GRAPPA's performance in relation to its 2016 goals and identify successes and areas for further improvement, identify key GRAPPA priorities and activities for the next 5 years, and explore committee structures to best support these aims.

Initiating Evaluation of Composite Outcome Measures for Psoriatic Arthritis: 2022 Updates From the GRAPPA-OMERACT Working Group

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) Psoriatic Arthritis (PsA) working group-comprising rheumatologists, dermatologists, methodologists, and patient research partners-provided updates at the GRAPPA 2022 annual meeting on its work to evaluate composite outcome measures for PsA. Ten composite outcome measures were considered. Initial steps were to define the population, the purpose of use, and the proposed pros and cons of the 10 candidate composite instruments for PsA. Preliminary Delphi exercises within the working group and GRAPPA stakeholders confirmed high priority for evaluating minimal disease activity (MDA); moderate priority for Disease Activity in PsA (DAPSA), American College of Rheumatology (ACR) response criteria, Psoriatic Arthritis Disease Activity Score (PASDAS), Composite Psoriatic Disease Activity Index (CPDAI), 3 visual analog scale (VAS), and 4VAS; and low priority for Disease Activity Score in 28 joints (DAS28), Psoriatic Arthritis Responder Criteria (PsARC), and Routine Assessment of Patient Index Data 3 (RAPID3). Further appraisal of candidate composite instruments is ongoing.

Bimekizumab treatment in biologic DMARD-naïve patients with active psoriatic arthritis: 52-week efficacy and safety results from the phase III, randomised, placebo-controlled, active reference BE OPTIMAL study

OBJECTIVES

Bimekizumab (BKZ) is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A. BKZ treatment has demonstrated superior efficacy versus placebo (PBO) at Week 16 in biologic disease-modifying antirheumatic drug (DMARD)-naïve patients with active psoriatic arthritis (PsA). Here, we report long-term efficacy and safety to Week 52.

METHODS

BE OPTIMAL comprised a 16-week, double-blind, PBO-controlled period, then 36 weeks treatment-blind. Patients were randomised 3:2:1 to subcutaneous BKZ 160 mg every 4 weeks, PBO with switch to BKZ at Week 16, or reference arm (adalimumab (ADA) 40 mg every 2 weeks). Efficacy outcomes included the American College of Rheumatology (ACR) response criteria 20/50/70, Psoriasis Area and Severity Index (PASI) 75/90/100 in patients with baseline psoriasis affecting ≥3% body surface area and minimal disease activity (MDA); non-responder imputation.

RESULTS

ACR20/50/70, PASI75/90/100 and MDA responses were sustained with BKZ to Week 52, consistent with results observed at Week 16. Patients who switched to BKZ at Week 16 demonstrated improvements in efficacy with similar results to BKZ-randomised patients by Week 52.To Week 52, 555/702 (79.1%) patients had ≥1 treatment-emergent adverse event (TEAE) during BKZ treatment; 113/140 (80.7%) on ADA. On BKZ, 46 (6.6%) patients had serious TEAEs. 54 (7.7%) Candida infections occurred during BKZ treatment and 1 (0.7%) during ADA; all cases were localised and non-serious. One death occurred in a BKZ-treated patient, unrelated to treatment.

CONCLUSIONS

The efficacy of BKZ in bDMARD-naïve patients with PsA was sustained from Week 16 to Week 52. BKZ was well tolerated with no new safety signals observed.

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.

Report of the Skin Research Workgroups From the IDEOM Breakout at the GRAPPA 2022 Annual Meeting

The International Dermatology Outcome Measures (IDEOM) organization presented an update on its progress related to patient-centered outcome measures for psoriasis (PsO) and psoriatic arthritis (PsA) at the 2022 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA). The Musculoskeletal (MSK) Symptoms working group presented an update on the development of the IDEOM Musculoskeletal Questionnaire (IDEOM MSK-Q). The IDEOM MSK-Q is a patient-reported outcome measure intended to capture MSK symptoms and describe their intensity and impact on health-related quality of life in patients with psoriatic disease. IDEOM also presented the progress of the integration of the Psoriasis Epidemiology Screening Tool (PEST) and Psoriatic Arthritis Impact of Disease (PsAID) questionnaires into the Epic electronic health record system. This will allow for automated PsA screening and symptom measurement in the hopes of improving disease detection and treat-to-target strategies. The Treatment Satisfaction working group discussed the development of the DermSat-7, a 7-item treatment satisfaction questionnaire specific for dermatological conditions. The DermSat-7 is currently being validated in a multicenter study of patients with PsO.

Dupilumab-Associated Arthritis: A Dermatology-Rheumatology Perspective

Dupilumab is an interleukin (IL)-4/13 inhibitor approved by the US FDA for multiple atopic indications. It is well-known to have favorable efficacy and safety profiles; however, emerging reports of dupilumab-associated arthritis suggest an underrecognized potential adverse effect. In this article, we summarize the literature to date to better characterize this clinical phenomenon. Arthritic symptoms were most commonly peripheral, generalized, and symmetric. Onset was generally within 4 months following initiation of dupilumab, and most patients resolved fully after a matter of weeks following discontinuation. Mechanistic insights suggest that suppression of IL-4 may lead to increased activity of IL-17, a prominent cytokine in inflammatory arthritis. We propose a treatment algorithm that stratifies patients by severity, recommending that patients with more mild disease continue dupilumab and treat through symptoms, while patients with more severe disease discontinue dupilumab and consider switching to another class (e.g., Janus kinase inhibitors). Lastly, we discuss important ongoing questions that should be addressed in future studies.

Safety and Efficacy of Tralokinumab in Older Adults With Moderate-to-Severe Atopic Dermatitis: A Secondary Analysis

Importance

Older adults with atopic dermatitis (AD) face unique treatment challenges, including comorbidities, polypharmacy, and a higher risk for infections (eg, herpes zoster). Furthermore, limited data are available from clinical trials for treatments in this population. In phase 3 studies, tralokinumab showed superior efficacy in moderate-to-severe AD vs placebo, but results were not stratified by age group.

Objective

To evaluate the safety and efficacy of tralokinumab in older (≥65 years) patients with moderate-to-severe AD.

Design, Setting, and Participants

A post hoc analysis for adults 65 years or older was conducted from a subset of patients in the US, Canada, Europe, and Asia in 3 randomized, placebo-controlled, phase 3 trials (ECZTRA 1 and 2 [monotherapy] and ECZTRA 3 [tralokinumab + topical corticosteroids as needed]). The post hoc data were analyzed in 2022.

Main Outcomes and Measures

Pooled data from up to 16 weeks of treatment from ECZTRA 1, 2, and 3 were used to assess safety. Statistical analyses followed prespecifications of primary end points. Separate efficacy analyses were conducted in these trials respectively at 16 weeks.

Results

A total of 75 older adults (42 women [56%]) treated with tralokinumab from the ECZTRA 1, 2, and 3 trials were included in this post hoc analysis. Similar proportions of patients reported adverse events (AEs) with tralokinumab and placebo (44 [58%]). Three patients (4%) in the tralokinumab arm and 3 (10.3%) in the placebo arm experienced severe AEs, and 4 (5.3%) and 2 (6.9%), respectively, had AEs leading to discontinuation. More patients achieved 75% or greater improvement in Eczema Area and Severity Index scores with tralokinumab than placebo (33.9% vs 4.8%; P < .001) in ECZTRA 1 and 2. Similar trends, although not statistically significant, were seen in ECZTRA 3. Safety and efficacy outcomes in this population were similar compared with the younger patient cohorts. The small sample size limited generalizations from this analysis.

Conclusion and Relevance

The results of this post hoc analysis suggest that tralokinumab is well tolerated and efficacious in patients 65 years or older with moderate-to-severe AD.

A Comprehensive Review of Ixekizumab Efficacy in Nail Psoriasis from Clinical Trials for Moderate-to-Severe Psoriasis and Psoriatic Arthritis

Nail psoriasis is a difficult-to-treat manifestation of psoriatic disease affecting up to 80% of patients with psoriatic arthritis (PsA) and 40-60% of patients with plaque psoriasis (PsO). Ixekizumab (IXE), a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for the treatment of patients with PsA and patients with moderate-to-severe PsO. This narrative review aims to summarize nail psoriasis data generated from IXE clinical trials in patients with PsA (SPIRIT-P1, SPIRIT-P2, and SPIRIT-H2H) and/or moderate-to-severe PsO (UNCOVER-1, -2, -3, IXORA-R, IXORA-S, and IXORA-PEDS) with an emphasis on head-to-head clinical trial data. Across numerous trials explored, IXE treatment was associated with greater improvement in resolution of nail disease versus comparators at week 24, results which were maintained up to and beyond week 52. Additionally, patients experienced higher rates of resolution of nail disease versus comparators at week 24 and maintained high levels of resolution up to week 52 and beyond. In both PsA and PsO, IXE demonstrated efficacy in treating nail psoriasis, and therefore may be an effective therapy option.

Cardiovascular Risk Management in Patients Treated with JAK Inhibitors

ABSTRACT

The Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway plays a critical role in the pathogenesis of many immune-mediated inflammatory diseases (IMIDs). Although Janus kinase inhibitors (JAKi) are an effective treatment for several IMIDs, they have come under scrutiny as a class due to a potential risk of venous thromboembolism (VTE) and cardiovascular (CV) events, specifically noted with the oral JAKi, tofacitinib, as reported in the ORAL Surveillance Trial of a high CV risk rheumatoid arthritis population. This trial resulted in a black box warning from the Food and Drug Administration and European Medicines Agency regarding risk of VTE and CV events that was extended across several types of JAKi (including topical ruxolitinib) when treating IMIDs, leading to considerable controversy. Included is an up-to-date review of the current and rapidly evolving literature on CV risk in patients with IMIDs on JAKi therapy, including identification of potential risk factors for future VTE and CV events on JAKi therapy. We suggest a comprehensive, multimodal, and systematic approach for evaluation of CV risk in patients considering taking JAKi and emphasize that cardiologists play an important role in risk stratification and mitigation for patients with high CV risk factors or on long-term JAKi therapies.

Ixekizumab Real-World Effectiveness at 24 Weeks in Patients with Psoriasis: Data from the United States Taltz Customer Support Program

INTRODUCTION

Ixekizumab, a highly selective interleukin-17A monoclonal antibody, was approved for the treatment of moderate-to-severe psoriasis (PsO) in 2016. Limited real-world data are available on its effectiveness from a patient's perspective shortly (2 to 4 weeks) after initiation and upon continuation for 24 weeks.

OBJECTIVE

To describe patient-reported clinical and quality-of-life outcomes after initiating ixekizumab using data collected from the United States Taltz® Customer Support Program.

METHODS

This was a 24-week prospective, observational study of commercially insured diagnosis-confirmed adults with PsO. Surveys were completed at weeks 0 (baseline), 2, 4, 8, 12, and 24 and included the Patient Report of Extent of Psoriasis Involvement questionnaire to assess the extent of body surface area (BSA) affected by PsO, itch and pain numeric rating scales, Patient Global Assessment of Disease Severity (PatGA), and Dermatology Life Quality Index (DLQI).

RESULTS

523 patients were included in the analysis. Proportions of patients with ≤ 2% BSA involvement were 34.5%, 40.1%, 50.9%, and 79.9% at weeks 0, 2, 4, and 24, respectively; 54.8% and 75.1% achieved National Psoriasis Foundation preferred (BSA ≤ 1%) and acceptable (BSA ≤ 3% or ≥ 75% improvement) responses at week 12, respectively. Improvements of ≥ 4 points in itch and pain were seen by week 2 in 21.1% and 28.0% of patients, respectively, which increased to 63.1% and 64.8% at week 24. Proportions of patients with PatGA scores of 0 (clear) or 1 were 13.4%, 24.1%, 34.0%, and 69.6% at weeks 0, 2, 4, and 24, respectively; and proportions with DLQI total scores of 0 or 1 [no or minimal impact] were 8.4%, 17.6%, 27.3%, and 53.8% at weeks 0, 2, 4, and 24, respectively.

CONCLUSION

Patient-reported improvements in BSA, itch, skin pain, dermatology-specific quality of life, and overall PsO severity were seen as early as 2 weeks after initiation and continued through week 24.

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.

A national survey comparing practice patterns and residency training satisfaction for categorical dermatology versus combined internal medicine and dermatology trained physicians

Combined internal medicine and dermatology (med-derm) training programs were created to advance complex medical dermatology and inpatient dermatology care. A prior study demonstrated that compared to categorical dermatology residents, med-derm residents had less program satisfaction, yet indicated a stronger desire to pursue careers in academia. No follow-up data on practice patterns after training has been reported. We aimed to characterize differences in residency program satisfaction and practice patterns between physicians trained in categorical dermatology compared to med-derm residency programs. We surveyed physicians who graduated from combined med-derm programs along with their counterparts, from six institutions, that either currently or historically had a combined med-derm training, from 2008-2017. Fifty-five percent of med-derm and forty-one percent of categorical-trained physicians responded. The practice patterns between the two groups were similar. A quarter of med-derm physicians continued to provide general internal medicine services. Categorical trained physicians were significantly more satisfied with their training (P=0.03) and performed more excisions on the head/neck (P=0.02). The combined graduates had significantly greater confidence in multidisciplinary care (P=0.003), prescribed more biologic (P<0.001) and non-biologic immunosuppressive agents (P=0.002), and volunteered more for the underserved patients in their communities (P=0.04). Although few differences in overall practice patterns between categorical and med-derm trained graduates were appreciated, med-derm graduates seem more comfortable with multidisciplinary care and may care for more medically complex patients requiring immunosuppression.
