Secukinumab demonstrates high sustained efficacy and a favourable safety profile in patients with moderate-to-severe psoriasis through 5 years of treatment (SCULPTURE Extension Study)

Successful treatment of generalized pustular psoriasis during pregnancy with secukinumab in a patient hypersensitive to spesolimab: a case report

OBJECTIVE

Generalized pustular psoriasis (GPP) is a rare autoinflammatory skin disease characterized by recurrent, widespread eruption of sterile pustules rich in neutrophils. In addition to skin manifestations, this condition may be accompanied by fever, muscle pain, joint pain, systemic inflammation, or organ failure. GPP during pregnancy poses a serious threat to both mother and fetus, with limited options for medication. This study aimed to evaluate the safety of secukinumab during pregnancy as a treatment option for psoriasis.

MATERIALS AND METHODS

We report the case of a 35-year-old pregnant woman presenting with extensive, confluent erythematous scaly plaques and numerous pustules, accompanied by fever. Over the past few years, her lesions showed remission following treatment with corticosteroids, traditional Chinese medicine, and secukinumab. However, after a brief remission with spesolimab, the lesions recurred and no significant improvement was obtained with glucocorticoid therapy. Secukinumab treatment was then initiated.

RESULTS

Secukinumab was administered subcutaneously at a dose of 300 mg at weeks 0, 1, 2, 3, 4, and 8. Following treatment, GPP symptoms were reduced, and fetal development remained normal. A healthy boy was delivered vaginally at term.

CONCLUSION

Our findings provide evidence that secukinumab is an effective and safe treatment option for GPP during pregnancy.

The preclinical discovery and development of secukinumab for the treatment of moderate-to-severe hidradenitis suppurativa

INTRODUCTION

Hidradenitis suppurativa (HS) is a chronic skin condition with a significant impact on patient quality of life, highlighting the need for innovative therapeutic approaches. HS is characterized by its chronicity; it presents in the form of painful nodules, abscesses, and sinus tracts or fistulas, typically localized in intertriginous areas, emerging in early adulthood and in predominantly the female population.

AREAS COVERED

In this review, the authors discuss the preclinical discovery and development of secukinumab for HS, highlighting target identification, validation, and compound selection. Methodologies such as high-content screening, chemoinformatics, and animal models that validate the IL-17 pathway's role in HS are explored. The transition from preclinical to clinical development, including pharmacokinetics (PK), pharmacodynamics (PD), and ADME-Tox studies, is elaborated. The literature search was conducted using PubMed, Web of Science, Scopus, UpToDate, Cochrane Library, Embase, and Google Scholar, covering relevant studies published up to December 2024.

EXPERT OPINION

The integration of secukinumab into HS treatment highlights the critical role of targeting the IL-17A pathway. Although efficacious and safe in trials, understanding secukinumab's long-term effects and optimal treatment placement remains challenging. Future research should prioritize the development of tailored therapeutic strategies that align with individual disease phenotypes and immune profiles to enhance treatment outcomes in HS management.

Tumor necrosis factor (TNF) inhibitors for psoriatic arthritis

BACKGROUND

Psoriatic arthritis (PsA) is a chronic arthritis affecting people with psoriasis. If untreated, it may lead to disability. Recommended drugs are non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), biologic DMARDs (bDMARDs), and targeted synthetic DMARDs (tsDMARDs). Tumour necrosis factor inhibitors (TNFi) are the first choice bDMARDs.

OBJECTIVES

To assess the benefits and harms of TNFi in adults with psoriatic arthritis.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, ClinicalTrials.gov and the World Health Organization trials portal up to 28 March 2024.

SELECTION CRITERIA

We included randomized controlled trials (RCTs) in adults with PsA, comparing TNFi to placebo, physiotherapy, NSAIDs, corticosteroids, and cs/b/tsDMARDs. Major outcomes included clinical improvement, minimal disease activity, physical function, health-related quality of life, radiographic progression, serious adverse events, and withdrawals due to adverse events.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. The primary comparison was TNFi versus placebo. The primary time point was 12 weeks for clinical improvement; 24 weeks for minimal disease activity, function, quality of life, and radiographic progression; and the end of the trial period for serious adverse events and withdrawals due to adverse events.

MAIN RESULTS

We included 25 RCTs randomizing 7857 participants. Four studies compared TNFi to methotrexate and one to ustekinumab in DMARD-naïve participants. In csDMARD-inadequate responders, 11 studies compared TNFi to placebo; four studies compared TNFi to placebo and ixekizumab, bimekizumab, tofacitinib, or upadacitinib; and three studies compared TNFi to ixekizumab, secukinumab, and ustekinumab. Two studies compared different TNFi. We found no studies with b/tsDMARD-inadequate responders (b/tsDMARD-IR). No studies compared TNFi to NSAIDs, corticosteroids, or physiotherapy. Performance (32%), detection (56%) and reporting (80%) biases were at high or unclear risk across studies. Only one study had a low risk of bias in all domains. We limit reporting to the primary comparison, TNFi versus placebo. DMARD-naïve We found no studies comparing TNFi with placebo in DMARD-naïve participants. csDMARD-inadequate responders TNFi probably result in a large clinical improvement compared to placebo. At 12 weeks, 149/1926 (8%) participants in the placebo group showed a clinical improvement (ACR50) compared to 784/2141 (37%) participants in the TNFi group (risk ratio (RR) 5.63, 95% confidence interval (CI) 3.98 to 7.96; I2 = 65%; 14 studies, 4067 participants; moderate-certainty evidence). TNFi probably result in a higher proportion of participants in minimal disease activity. At 24 weeks, 95/1017 (9%) participants in the placebo group were in minimal disease activity compared to 428/1336 (32%) participants in the TNFi group (RR 3.76, 95% CI 2.39 to 5.92; I2 = 72%; 5 studies, 2353 participants; moderate-certainty evidence). At 24 weeks, TNFi may improve function compared to placebo. The mean change in function from baseline (assessed with the Health Assessment Questionnaire; score from 0 to 3, 0 = no disability; minimal clinically important difference (MCID) = 0.35) was -0.14 points with placebo and 0.33 points lower (0.41 lower to 0.25 lower) with TNFi (I2 = 72%; 8 studies, 2949 participants; low-certainty evidence). TNFi probably result in a clinically important improvement in health-related quality of life. The mean change in quality of life from baseline (assessed with the Short Form 36-item Mental Component Summary questionnaire; score from 0 to 100, 100 = best score; MCID = 1.7) was 2.4 points with placebo and 3.29 points higher (2.18 points higher to 4.40 points higher) with TNFi (I2 = 52%; 8 studies, 2928 participants; moderate-certainty evidence). TNFi probably slightly reduce radiographic progression. The mean change in radiographic progression (assessed with the Sharp/Van der Heijde-PsA score; scale from 0 to 528, 0 = no damage) was 0.25 points with placebo and 0.37 points lower with TNFi (0.48 lower to 0.25 lower) (I2 = 32%; 7 studies, 2478 participants; moderate-certainty evidence) at 24 weeks. We downgraded the evidence to moderate certainty for clinical improvement, minimal disease activity, quality of life, and radiographic progression due to risk of bias. For function, we downgraded the evidence to low certainty for risk of bias and imprecision. TNFi may result in little to no difference in serious adverse events, but may slightly increase withdrawals due to adverse events, compared to placebo. At the end of follow-up: 56/1826 participants (3%) given placebo and 69/1900 (4%) participants given TNFi experienced serious adverse events (RR 1.00, 95% CI 0.70 to 1.42; I2 = 0%; 13 studies, 3866 participants; low-certainty evidence); and 35/1926 (2%) participants given placebo and 65/2140 (3%) given TNFi withdrew due to adverse events (RR 1.53, 95% CI 1.01 to 2.33; I2 = 0%; 14 studies, 4066 participants; low-certainty evidence). We downgraded the evidence to low certainty for risk of bias and imprecision.

AUTHORS' CONCLUSIONS

In csDMARD-inadequate responders, moderate-certainty evidence showed that TNFi probably result in a large clinical improvement, lower disease activity, small decrease in radiographic progression, and better quality of life compared to placebo. Low-certainty evidence showed that TNFi may lead to a slight improvement in physical function compared to placebo. Low-certainty evidence suggested that TNFi may lead to a slight increase in withdrawals due to adverse events, whereas they may result in little to no difference in serious adverse events compared to placebo. No trials assessed TNFi compared to placebo in DMARD-naïve participants or in b/tsDMARD-IR.

From the Masterclasses in Dermatology 2024 Meeting: Updates in Psoriasis Treatments

Psoriasis (PsO) is an immune-mediated, chronic inflammatory skin disease that significantly impairs quality of life. Its treatment landscape is rapidly evolving, providing better disease control. Here, we highlight updates in biologics, obtaining coverage for biologics under Medicare, the PsO-to-psoriatic arthritis (PsA) transition, and orally administered drugs, as presented at the 2024 Masterclass in Dermatology in Puerto Rico. We provide a concise overview of the evolving therapeutic landscape and its impact on personalized care for patients with PsO. The toolkit of biologics is expanding, with agents that target interleukin (IL)-17 and IL-23 pathways addressing symptoms across multiple disease domains. Interchangeable biosimilars reduce financial barriers to access, particularly for tumor necrosis factor (TNF) inhibitors. An IL-36 receptor antibody, spesolimab, demonstrates efficacy in generalized pustular psoriasis. Further, Medicare has expanded coverage of certain biologics, addressing challenges to treating patients of this population. PsA is an important comorbidity that can significantly reduce quality of life. Recent studies suggest that biologic therapies-including TNF inhibitors, as well as anti-IL-17, anti-IL-23, and anti-IL-12/23 agents-protect against arthritis onset in PsO patients. In addition to traditional modes of delivery, novel formulations address widespread preference for orally administered therapies. Deucravacitinib, a tyrosine kinase (TYK) 2 inhibitor, is highly selective, effective, and safe. Additionally, JNJ-77242113, an investigational IL-23 receptor antagonist, constitutes an orally administered, targeted biologic therapy. Together, these developments are shaping the future for patients with PsO. It is our goal to simplify the complexities of emerging treatment options, offering clinicians a concise and useful guide for patient management.

Real-Life Data of Secukinumab in Patients with Moderate to Severe Plaque Psoriasis, Psoriatic Arthritis, and Ankylosing Spondylitis: Patient Baseline Characteristics Data from the PROMPT Study

INTRODUCTION

Secukinumab has proven to be effective and safe in psoriasis (PsO), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) in the phase 3 studies. However, data on real-world practice is limited.

METHODS

This study is an ongoing, multicenter, 2-year observational study that focuses on patients with moderate to severe plaque PsO, active PsA, or AS receiving secukinumab. The aim of this study is to present baseline data for the entire study population.

RESULTS

A total of 127 patients were enrolled, with 101 having PsO, 12 with PsA, and 14 with AS. Among the patients, approximately 54.0% were male. The mean body mass index ranged from 25.0 to 27.4 kg/m2 across all groups. Patients with PsO had the longest disease duration with an average of 11.0 years, followed by AS (3.0 years) and PsA (1.0 year). Previous biologic therapy was observed in 6.9-8.1% of patients. Baseline disease severity scores revealed moderate to severe disease. In the PsO group, the mean Psoriasis Area and Severity Index score was 16.1. For patients with PsA, the mean Tender Joint Count was 9.1, and the mean Swollen Joint Count was 6.7. In the AS group, the mean Bath Ankylosing Spondylitis Disease Activity Index score was 4.6, and the mean Ankylosing Spondylitis Disease Activity Score was 3.7.

CONCLUSION

The study demonstrates disease durations, disease activity, and treatment history in Thai patients that were generally consistent with previous randomized controlled studies. Long-term data on the efficacy and safety of the treatment will be presented in future publications.

The role of interleukin-17 and interleukin-23 inhibitors in the development, progression, and recurrence of cancer: A systematic review

Background

Biologicals targeting interleukin (IL)-17 and IL-23 improve quality of life in psoriasis and other chronic autoimmune disorders with a favorable safety profile. However, current guidelines do not recommend their use in patients with recent oncologic history due to limited evidence.

Objective

To understand the impact of IL-17 and IL-23 inhibitors on cancer development, progression, and recurrence by systematically reviewing available literature.

Methods

We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results

Most studies investigating the use of IL-23 and IL-17 blockers did not find a higher incidence of cancer compared to the general population. One study observed no relapse in patients with a history of cancer.

Limitations

The systematic review is limited due to variations in study designs and outcomes, making it difficult to achieve a comprehensive synthesis and comparison between studies. Furthermore, small sample sizes were notable.

Conclusion

Preclinical studies suggest that treating psoriasis with IL-17 or IL-23 blockers is safe, also in patients witch active cancer or a history of it. Pharmacovigilance data show no increased malignancy rate in patients treated with these treatment modalities. However, data on relapse in patients with a history or active malignancy are limited.

Dual blockade of IL-17A and IL-36 pathways via a bispecific antibody exhibits enhanced anti-inflammatory potency

Antibody drugs targeting single inflammatory cytokines have revolutionized the treatment of immune-mediated inflammatory diseases. To investigate whether dual targeting interleukin-17 (IL-17) and IL-36 enhances anti-inflammatory activity, bispecific Ab HB0043 was generated by linking the single chain fragment variables (scFvs) from humanized anti-IL-36R antibody (HB0034) to the C-terminus of the heavy chain of anti-IL-17A IgG1 (HB0017) Fc using a flexible peptide linker. HB0043 largely maintained the binding affinities and biological activities of the two parent monoclonal antibodies (mAbs) in vitro. IL-17 and IL-36 cooperated to amplify the expression of pro-inflammatory and pro-fibrotic genes in normal human dermal fibroblasts (NHDF). However, HB0043 more effectively blocked IL-6 and IL-8 production in NHDF stimulated by IL-17A and IL-36 compared to two monoclonal antibodies. In a mouse model of Oxazolone (OXA)-induced atopic dermatitis and Imiquimod (IMQ)-induced skin inflammation, administration of both anti-IL17A mAb HB0017 and anti-mouse IL-36R surrogate antibody HB0034SA showed improved effectiveness in alleviating skin thickening and inflammation based on histological assessment. Further, in cynomolgus monkeys, HB0043 showed no enhanced target-related toxicity compared with the two parental mAbs in vivo and with a moderate increase in production of anti-drug antibodies. Together, dual blockade of IL-17A and IL-36R in the form of a bispecific antibody may have advantages in blocking the overlapping and non-overlapping functions of these two cytokines in skin inflammation that could not optimally be curtailed with single mAbs. In conclusion, as monotherapy may reach therapeutic celling for certain difficult-to-treat inflammatory and fibrotic diseases, dual targeting could potentially pave a way to combat these diseases.

Assessing the 5-year persistence in positive clinical response with innovative psoriasis treatments: a network meta-analysis of Psoriasis Area and Severity Index score

BACKGROUND

Psoriasis is a chronic skin condition, for which the approval of several biologics has made a dramatic impact. Despite their initial treatment effectiveness, the challenge lies in understanding the long-term responses, as they may diminish over time. Limitations of drug survival analysis warrant the application of additional outcomes to fully capture the performance of a biologic.

OBJECTIVES

To provide a broader perspective on the global landscape of biologic agents' persistence in positive clinical response by comparing innovative therapies over a 5-year period through a systematic review and network meta-analysis.

METHODS

We comprehensively identified studies in PubMed, Embase, Scopus and ClinicalTrials.gov. We defined two outcomes: (i) 'persistence at optimal response' (POR) or 'clinical remission', and (ii) 'persistence at suboptimal response' (PSR) or 'low disease activity'. Outcomes were measured as the proportions of patients with continuous exposure to a biologic who achieved ≥ 90% or 100% improvement in Psoriasis Area and Severity Index at the end of the predefined 5-year follow-up period.

RESULTS

Eleven publications, comprising 18 randomized controlled trials and 11 202 patients, met the inclusion criteria and were included in the network meta-analysis. In the ranking analysis, guselkumab exhibited the highest cumulative probability of POR (0.84), followed by ixekizumab (0.82) and risankizumab (0.76). Conversely, etanercept (0.42), brodalumab (0.36), apremilast (0.25) and placebo (0.026) showed the lowest cumulative probabilities of POR. For PSR, guselkumab (0.86), ixekizumab (0.75) and risankizumab (0.71) also ranked highest, while brodalumab (0.42), secukinumab (0.23), etanercept (0.19) and placebo (0.019) presented the lowest PSR probabilities.

CONCLUSIONS

The highest rates of persistence with clear or almost clear skin can be expected with guselkumab, ixekizumab and risankizumab compared with other biologics. The proposed proxy definitions of long-term persistence (POR and PSR) are reliable measures of patients being successfully treated that warrant further exploration and validation.

Biologics as a novel treatment option for palmoplantar pustulosis: a comprehensive review

Introduction

Palmoplantar pustulosis (PPP) is a complex inflammatory skin disease. Currently, no standardized treatments exist, and traditional systemic therapies often display limited effectiveness and substantial adverse effects. Biologics, however, have shown potential for enhanced clinical outcomes in psoriasis patients, thereby prompting this investigation into their applicability in PPP treatment.

Aim

This study constitutes the first comprehensive review to assess the effectiveness and underlying mechanisms of biologics for PPP.

Material and methods

We conducted a PubMed search to identify studies on biologics for PPP from 1992 onward. The review focused on assessing the efficacy of biologics targeting cytokines like IL-1, IL-8, IL-17, IL-12/23, IL-36, and TNF-α.

Results

Biologics for PPP are generally less effective than for psoriasis. Secukinumab and guselkumab, IL-17 and IL-23 inhibitors respectively, have shown better results compared to other biologics in trials. However, the effectiveness of other biologics remains uncertain due to limited data.

Conclusions

More research is needed to find effective treatments for PPP, and selecting the right biologic for each patient is challenging.

Safety, Pharmacokinetics, and Pharmacodynamics of Etrasimod: Single and Multiple Ascending Dose Studies in Healthy Adults

Etrasimod is an investigational, once-daily, oral, selective sphingosine 1-phosphate receptor 1,4,5 modulator in development for immune-mediated inflammatory diseases (IMIDs). Here, we report the human safety, pharmacokinetics, and pharmacodynamics of etrasimod obtained from both a single ascending dose (SAD; 0.1-5 mg) study and a multiple ascending dose (MAD; 0.35-3 mg once daily) study. Overall, 99 healthy volunteers (SAD n = 40, MAD n = 59) completed the 2 studies. Evaluated single and multiple doses were well tolerated up to 3 mg without severe adverse events (AEs). Gastrointestinal disorders were the most common etrasimod-related AEs. Over the evaluated single- and multiple-dose ranges, dose-proportional and marginally greater-than-dose-proportional etrasimod plasma exposure were observed, respectively. At steady state, etrasimod oral clearance and half-life mean values ranged from 1.0 to 1.2 L/h and 29.7 to 36.4 hours, respectively. Dose-dependent total peripheral lymphocyte reductions occurred following etrasimod single and multiple dosing. Etrasimod multiple dosing resulted in reductions from baseline in total lymphocyte counts ranging from 41.1% to 68.8% after 21 days. Lymphocyte counts returned to normal range within 7 days following treatment discontinuation. Heart rate lowering from pretreatment baseline on etrasimod dosing was typically mild, with mean reductions seen after the first dose of up to 19.5 bpm (5 mg dose). The favorable safety, pharmacokinetic, and pharmacodynamic properties of etrasimod in humans supported its further development and warranted its investigation for treatment of IMIDs.

Effectiveness of secukinumab in patients with psoriasis and psoriatic arthritis in a Saudi real-world setting

INTRODUCTION

Psoriasis (PsO) is an immune-mediated chronic inflammatory disease that results in severe outcomes that impact the patient's quality of life and work productivity. We investigated the effectiveness of secukinumab in patients with chronic plaque psoriasis and psoriatic arthritis (PsA) over a 12-month period.

METHODS

This was a longitudinal, retrospective study of the medical records of 81 patients with psoriasis and/or psoriatic arthritis who had been treated with secukinumab for at least 12 weeks.

RESULTS

The Psoriasis Area Severity Index (PASI), Body Surface Area (BSA) percentage, and Dermatology Quality of Life Index (DLQI) among patients with PsO and PsO-PsA showed a statistically significant decrease from baseline over 12 months by approximately 9.86, 19.3%, and 9.7, respectively (p values < 0.001 for each). Moreover, there was a statistically significant decrease in the overall Disease Activity in Psoriatic Arthritis score (DAPSA) by approximately 22.35 from baseline over 12 months of treatment (p < 0.001). Considering the patients who started secukinumab 12 months or more prior to the study cutoff date, the 12-month retention rate was 85%.

CONCLUSION

In a Saudi real-world setting, secukinumab proved to be an efficient medication with high efficacy and retention rates.

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.

A Real-Life 208 Week Single-Centred, Register-Based Retrospective Study Assessing Secukinumab Survival and Long-Term Efficacy and Safety Among Greek Patients with Moderate to Severe Plaque Psoriasis, Including Difficult-to-Treat Manifestations Such as Genitals and Scalp

INTRODUCTION

Psoriasis is a chronic inflammatory disease with multiple skin manifestations, and in case of lesions affecting the genital area, sexual health impairment and psychological distress can furthermore impair the patients quality of life. Secukinumab is a fully humanized immunoglobulin G1 kappa antagonist of IL-17A and is indicated for the treatment of moderate-to-severe psoriasis, since it shows a significant efficacy in clinical outcomes, with rapid onset of remission, prolonged treatment response rate, advantageous safety profile and a valuable improvement of the patients quality of life.

OBJECTIVES

This study was conducted in order to gather retrospective real-world data regarding the efficacy of secukinumab in treating patients with moderate-to-severe plaque psoriasis in Greece. To fill the relevant literature gap, we included difficult-to-treat manifestations in our analysis, specifically regarding the efficacy in the genital area and on the skin folds where relevant data are missing both from the drug clinical program as well as from the real-world setting.

METHODS

All adult patients receiving 300 mg secukinumab and attending follow-up visits on a regular basis, according to routine medical practice were included. The timeline of the study was from 2015 to 2020. Primary endpoint of the study was the percentage of patients who achieved a psoriasis area and severity index (PASI) 75 response rate at week 16 and week 52 post baseline. Secondary endpoints were the evaluation at baseline (week 0), week 4 (±1), week 16 (±1), week52 (±1), and week 104 (±1), week 156 (±1), week 208 (±1) of clinical outcomes, incidence of adverse events and potential predictive variables influencing response rate.

RESULTS

Ninety-nine patients were included in the study population, from whom sixty six patients (66.67%) were bio-naive, whereas 33 patients had never received systemic treatment. Regarding difficult-to-treat manifestations, we recorded scalp involvement in 74.74% (74/99) of our patients, genital psoriasis in 27.27% (27/99) and skin folds involvement (psoriasis inversa) in 17% (17/99). At week 16, PASI75/PASI90/PASI100 were observed in 87.5%/69.8%/49%, respectively. At week 4 lesions affecting the genital area and patients with skin fold involvement experienced a rapid regression and 84.1% of patients achieved sPGA 0/1 (Physician Global Assessment). Treatment with secukinumab during the 208 weeks of observation did not reveal any major adverse event or systemic infection and generally it was well tolerated.

CONCLUSIONS

According to our outcomes secukinumab is an effective treatment choice for treating chronic plaque psoriasis, but, additionally, it can be efficacious in the subgroups of patients with difficult-to-treat manifestations, as our patients experienced great improvement starting even 5 weeks after treatment initiation. This real-life study offers information about clinical efficacy, retention and safety profile of secukinumab in patients from everyday clinical practice over a long-term, 4-year, follow-up period in Greece.

Dose reduction is a feasible strategy in patients with plaque psoriasis who achieve sustained response with secukinumab: a retrospective, multicenter cohort study in daily practice setting

BACKGROUND

Biological therapy dose modification is a common practice in the long-term treatment of plaque psoriasis.

OBJECTIVE

The objective of the study was to determine prevalence, characteristics of patients, effectiveness, treatment survival of secukinumab dose reduction (SEC-DR) strategy and assess its safety and cost implications.

METHODS

A retrospective, observational, multicenter cohort study was conducted in patients with plaque psoriasis treated with secukinumab and up to 2 years of follow-up.

RESULTS

In 63/347 patients with an initial standard dose regimen, SEC-DR was tried at any moment in 18.2% of them after sustained response. In 51 patients, the interval between administrations was increased while in 12 patients, monthly dose was reduced to 150 mg. Successful SEC-DR was achieved in 77.8% of the patients, with sustained PASI response to the end of the study. Survival of secukinumab treatment and safety profile were not compromised by DR. The use of DR saved 33% of the cost, including failures in which standard treatment was resumed.

LIMITATIONS

The proper of the study designed and the arbitrary definition of "DR success."

CONCLUSION

Off-label SEC-DR strategy was used in patients with sustained response to standard dose regimen; this strategy showed long-term efficacy without compromising treatment survival or worsening the safety profile while also being cost saving.

Long-Term Drug Survival and Effectiveness of Secukinumab in Patients with Moderate to Severe Chronic Plaque Psoriasis: 42-Month Results from the SUPREME 2.0 Study

Purpose

SUPREME, a phase IIIb study conducted in Italy, demonstrated safety and high efficacy of secukinumab for up to 72 weeks in patients with moderate-to-severe plaque-type psoriasis. SUPREME 2.0 study aimed to provide real-world data on the long-term drug survival and effectiveness of secukinumab beyond 72 weeks.

Patients and Methods

SUPREME 2.0 is a retrospective observational chart review study conducted in patients previously enrolled in SUPREME study. After the end of the SUPREME study, eligible patients continued treatment as per clinical practice, and their effectiveness and drug survival data were retrieved from medical charts.

Results

Of the 415 patients enrolled in the SUPREME study, 297 were included in SUPREME 2.0; of which, 210 (70.7%) continued secukinumab treatment throughout the 42-month observation period. Patients in the biologic-naïve cohort had higher drug survival than those in the biologic-experienced cohort (74.9% vs 61.7%), while HLA-Cw6-positive and HLA-Cw6-negative patients showed similar drug survival (69.3% and 71.9%). After 42 months, Psoriasis Area and Severity Index (PASI) 90 was achieved by 79.6% of patients overall; with a similar proportion of biologic-naïve and biologic-experienced patients achieving PASI90 (79.8% and 79.1%). The mean absolute PASI score reduced from 21.94 to 1.38 in the overall population, 21.90 to 1.24 in biologic-naïve and 22.03 to 1.77 in biologic-experienced patients after 42 months. The decrease in the absolute PASI score was comparable between HLA-Cw6-positive and HLA-Cw6-negative patients. The baseline Dermatology Life Quality Index scores also decreased in the overall patients (10.5 to 2.32) and across all study sub-groups after 42 months. Safety was consistent with the known profile of secukinumab, with no new findings.

Conclusion

In this real-world cohort study, secukinumab showed consistently high long-term drug survival and effectiveness with a favourable safety profile.

Entwicklung der Patientencharakteristika und der Wirksamkeit der Biologika-Therapie bei Patienten des Österreichischen Psoriasis-Registers von 2004 bis 2022

Hintergrund und Ziele

In dieser Studie wurde untersucht, inwieweit die Einführung wirksamerer Medikamente in jüngster Zeit zu einer Verbesserung der Behandlungsergebnisse von Psoriasis‐Patienten im klinischen Alltag geführt hat.

Patienten und Methodik

Es wurden Patientencharakteristika und die Wirksamkeit der Therapie im ersten Behandlungsjahr bei Biologika‐naiven Patienten von 2004 bis heute analysiert, unabhängig von Therapiewechseln.

Ergebnisse

Die Daten von 2729 Patienten eigneten sich für die Analyse. Der Anteil der weiblichen Patienten stieg über die Jahre signifikant von 29,9% auf 36,2% (p < 0,028), während der Anteil der Patienten mit einer Psoriasis‐Arthritis von 36,6% auf 30,0% sank (p < 0,001). Außerdem nahm die Dauer der Psoriasis‐Erkrankung und der PASI‐Wert zu Beginn der Behandlung in Verlauf der Zeit signifikant ab. Die „letzte Beobachtung übernommen“ (LOCF)‐Analyse zeigte, dass das PASI‐90‐Ansprechen drei Monate nach Therapiebeginn von 18,9% auf 44,6% und 12 Monate nach Therapiebeginn von 32,9% auf 66,8% anstieg. Ebenso stiegen die PASI<3 Befunde von 33,2% auf 66,0% 3 Monate und von 41,9% auf 78,9% 12 Monate nach Behandlungsbeginn.

Schlussfolgerungen

Die kontinuierliche Einführung wirksamerer Biologika hat zu einer deutlichen Verbesserung des klinischen Ansprechens und der Patientenversorgung geführt. Dennoch erreicht auch heute noch, je nach gewähltem Endpunkt, jeder dritte bis fünfte Patient kein vollständig zufriedenstellendes Behandlungsergebnis (d.h. PASI 90 oder PASI ≤ 3).

Evolution of characteristics and biologic treatment effectiveness in patients of the Austrian psoriasis registry from 2004-2022

BACKGROUND AND OBJECTIVES

This study analyzed the extent to which the recent introduction of more effective treatments has led to an improvement in real-world psoriasis patients.

PATIENTS AND METHODS

Patient characteristics and the first-year treatment effectiveness in biologic-naive patients have been analyzed since 2004 until now, irrespective of treatment switches.

RESULTS

Data from 2,729 patients were eligible for this analysis. The proportion of female patients increased significantly over the years from 29.9% to 36.2% (p < 0.028), while the number of patients with psoriatic arthritis declined from 36.6% to 30.0% (p < 0.001). Moreover, the duration of psoriatic disease and PASI at the start of the treatment significantly decreased. Last observation carrief forward (LOCF) analysis indicated that PASI 90 response increased from 18.9 to 44.6% at 3 months and from 32.9 to 66.8% at 12 months after treatment started. Similary, the PASI ≤ 3 rates increased from 33.2% to 66.0% at 3 months and from 41.9% to 78.9% at 12 months after the treatment started.

CONCLUSIONS

The continuous introduction of more efficient biologics has led to significant improvements in patient care and clinical outcomes. Though one out of three to five patients, depending on the endpoint selected, nowadays still does not achieve an entirely satisfactory treatment response (i.e., PASI 90 or PASI ≤ 3).

Short-term risk and long-term incidence rate of infection and malignancy with IL-17 and IL-23 inhibitors in adult patients with psoriasis and psoriatic arthritis: a systematic review and meta-analysis

The risk of infection and malignancy may be a concern for patients with psoriasis receiving interleukin (IL)-17 and IL-23 inhibitors, particularly with long-term treatments. We aimed to estimate the short-term risks and long-term incidence rates of infection and malignancy with IL-17 or IL-23 antagonists in adult patients with psoriasis and psoriatic arthritis through this comprehensive meta-analysis (PROSPERO registration number: CRD42022363127). We searched PubMed, MEDLINE, Web of Science and ClinicalTrials.gov until May 17, 2023 for randomized placebo-controlled trials and long-term (≥ 52 weeks) open-label extension studies. The estimates of short-term risk ratios (RRs) and long-term exposure-adjusted incidence rates (EAIRs) were pooled using R software 4.1.1 and STATA 16.0. This review included 45 randomized placebo-controlled studies and 27 open-label extension studies. Short-term RRs of serious infection, overall infection and malignancy were 1.45 (95% confidence intervals, 95% CI: 0.81-2.59), 1.20 (95% CI: 1.06-1.35), 0.83 (95% CI: 0.41-1.71) with IL-17 inhibitors; and 0.68 (95% CI: 0.38-1.22), 1.13 (95% CI: 1.00-1.28), 0.87 (95% CI: 0.37-2.04) with IL-23 inhibitors. Increased short-term risks of nasopharyngitis and Candida infection with IL-17 inhibitors were found. Long-term EAIRs of serious infection, overall infection, nonmelanoma skin cancer (NMSC), malignancies excluding NMSC, nasopharyngitis and upper respiratory tract infection were 1.11/100 patient-years (PYs), 57.78/100PYs, 0.47/100PYs, 0.24/100PYs, 15.07/100PYs, 8.52/100PYs, 3.41/100PYs with IL-17 inhibitors; and 1.09/100PYs, 48.50/100PYs, 0.40/100PYs, 0.43/100PYs, 10.75/100PYs, 5.84/100PYs with IL-23 inhibitors. Long-term EAIR of Candida infection was 3.41/100PYs with IL-17 inhibitors. No active or reactivated tuberculosis was ever reported in all the trials, and only a few cases of latent tuberculosis, hepatitis, and herpes zoster were reported during the long-term extension periods. No evidence of increased EAIRs of infection and malignancy with longer durations was found. Our study suggested that short-term risk and long-term incidence of infections and malignancies in psoriasis patients receiving IL-17 inhibitors and IL-23 inhibitors are generally low. However, close monitoring is required for nasopharyngitis and Candida infection with IL-17 inhibitors.

Real-world retention rates and effectiveness of secukinumab in psoriasis: Results from a multicenter cohort study (RAILWAY)

Psoriasis is a chronic, immune-mediated inflammatory skin disease with a high negative impact on patient's quality of life. Secukinumab, the first interleukin 17A inhibitor, has been used for the systemic treatment of psoriasis, but its long-term, real-world retention rates in Japan have not been fully investigated. In this multicenter, noninterventional, retrospective chart review study, the retention rate of secukinumab and its effectiveness among patients with psoriasis in Japan was evaluated up to 5 years. Data of patients who received secukinumab after December 26, 2014, were collected from medical charts obtained from seven sites, all certified for biologics use by the Japanese Dermatological Association. Patient characteristics, secukinumab retention, factors affecting secukinumab retention, reason for drug discontinuation, and effectiveness data were collected. The primary end point was secukinumab retention rate at week 52. A total of 123 patients were included in the analysis. Of these, 27 patients discontinued secukinumab by week 52, yielding a 78.0% (95% confidence interval, 69.6-84.4) retention rate at week 52. For patients whose Psoriasis Area and Severity Index (PASI) score was available, mean ± standard deviation PASI at baseline and at week 52 were 9.21 ± 7.37 and 1.4 ± 2.6, respectively. During the entire study period, "insufficient response" was the most common reason for discontinuation, and "history of biologics use" was a factor significantly associated with secukinumab discontinuation (hazard ratio, 1.72; p = 0.018). This study demonstrates the real-world retention rate and effectiveness of secukinumab in patients with psoriasis in Japan for up to 5 years and provides clinical insights into psoriasis treatment strategies.

Real-world evidence for secukinumab in UK patients with psoriatic arthritis or radiographic axial spondyloarthritis: interim 2-year analysis from SERENA

Objectives

The aim was to evaluate retention rates for secukinumab in patients with active PsA or radiographic axial spondyloarthritis (r-axSpA) treated in routine UK clinical practice.

Methods

SERENA (CAIN457A3403) is an ongoing, non-interventional, international study of patients with moderate-to-severe chronic plaque psoriasis, active PsA or active r-axSpA, who had received secukinumab for ≥16 weeks before enrolment. The primary objective of this interim analysis was to assess treatment retention rates in patients with PsA or r-axSpA who were enrolled and followed for ≥2 years at centres in the UK. The safety analysis set includes all patients who received at least one dose of secukinumab. The target population set includes all patients who fulfilled the patient selection criteria.

Results

The safety set comprised 189 patients (PsA, n = 81; r-axSpA, n = 108), and the target population set comprised 183 patients (PsA, n = 78; r-axSpA, n = 105). In the safety set, 107 patients (45 of 81 with PsA and 62 of 108 with r-axSpA) had previously received a biologic agent. Retention rates were similar between patients with PsA and r-axSpA after 1 year (PsA 91.0%, 95% CI: 84.0, 98.0; r-axSpA 89.2%, 95% CI: 82.7, 95.7) and 2 years (PsA 77.6%, 95% CI: 67.6, 87.7; r-axSpA 76.2%, 95% CI: 67.4, 85.0) of observation. Overall, 17.5% of patients (33 of 189) experienced at least one treatment-related adverse event, and 12.7% of patients (24 of 189) discontinued secukinumab because of adverse events.

Conclusion

This analysis of real-world data from the UK demonstrates high retention rates for secukinumab over 2 years in patients with PsA or r-axSpA, with a favourable safety profile.

Systemic pharmacological treatments for chronic plaque psoriasis: a network meta-analysis

BACKGROUND

Psoriasis is an immune-mediated disease with either skin or joints manifestations, or both, and it has a major impact on quality of life. Although there is currently no cure for psoriasis, various treatment strategies allow sustained control of disease signs and symptoms. The relative benefit of these treatments remains unclear due to the limited number of trials comparing them directly head-to-head, which is why we chose to conduct a network meta-analysis.

OBJECTIVES

To compare the benefits and harms of non-biological systemic agents, small molecules, and biologics for people with moderate-to-severe psoriasis using a network meta-analysis, and to provide a ranking of these treatments according to their benefits and harms.

SEARCH METHODS

For this update of the living systematic review, we updated our searches of the following databases monthly to October 2022: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of systemic treatments in adults over 18 years with moderate-to-severe plaque psoriasis, at any stage of treatment, compared to placebo or another active agent. The primary outcomes were: proportion of participants who achieved clear or almost clear skin, that is, at least Psoriasis Area and Severity Index (PASI) 90; proportion of participants with serious adverse events (SAEs) at induction phase (8 to 24 weeks after randomisation).

DATA COLLECTION AND ANALYSIS

We conducted duplicate study selection, data extraction, risk of bias assessment, and analyses. We synthesised data using pairwise and network meta-analysis (NMA) to compare treatments and rank them according to effectiveness (PASI 90 score) and acceptability (inverse of SAEs). We assessed the certainty of NMA evidence for the two primary outcomes and all comparisons using CINeMA, as very low, low, moderate, or high. We contacted study authors when data were unclear or missing. We used the surface under the cumulative ranking curve (SUCRA) to infer treatment hierarchy, from 0% (worst for effectiveness or safety) to 100% (best for effectiveness or safety).

MAIN RESULTS

This update includes an additional 12 studies, taking the total number of included studies to 179, and randomised participants to 62,339, 67.1% men, mainly recruited from hospitals. Average age was 44.6 years, mean PASI score at baseline was 20.4 (range: 9.5 to 39). Most studies were placebo-controlled (56%). We assessed a total of 20 treatments. Most (152) trials were multicentric (two to 231 centres). One-third of the studies (65/179) had high risk of bias, 24 unclear risk, and most (90) low risk. Most studies (138/179) declared funding by a pharmaceutical company, and 24 studies did not report a funding source. Network meta-analysis at class level showed that all interventions (non-biological systemic agents, small molecules, and biological treatments) showed a higher proportion of patients reaching PASI 90 than placebo. Anti-IL17 treatment showed a higher proportion of patients reaching PASI 90 compared to all the interventions. Biologic treatments anti-IL17, anti-IL12/23, anti-IL23, and anti-TNF alpha showed a higher proportion of patients reaching PASI 90 than the non-biological systemic agents. For reaching PASI 90, the most effective drugs when compared to placebo were (SUCRA rank order, all high-certainty evidence): infliximab (risk ratio (RR) 49.16, 95% CI 20.49 to 117.95), bimekizumab (RR 27.86, 95% CI 23.56 to 32.94), ixekizumab (RR 27.35, 95% CI 23.15 to 32.29), risankizumab (RR 26.16, 95% CI 22.03 to 31.07). Clinical effectiveness of these drugs was similar when compared against each other. Bimekizumab and ixekizumab were significantly more likely to reach PASI 90 than secukinumab. Bimekizumab, ixekizumab, and risankizumab were significantly more likely to reach PASI 90 than brodalumab and guselkumab. Infliximab, anti-IL17 drugs (bimekizumab, ixekizumab, secukinumab, and brodalumab), and anti-IL23 drugs except tildrakizumab were significantly more likely to reach PASI 90 than ustekinumab, three anti-TNF alpha agents, and deucravacitinib. Ustekinumab was superior to certolizumab. Adalimumab, tildrakizumab, and ustekinumab were superior to etanercept. No significant difference was shown between apremilast and two non-biological drugs: ciclosporin and methotrexate. We found no significant difference between any of the interventions and the placebo for the risk of SAEs. The risk of SAEs was significantly lower for participants on methotrexate compared with most of the interventions. Nevertheless, the SAE analyses were based on a very low number of events with very low- to moderate-certainty evidence for all the comparisons. The findings therefore have to be viewed with caution. For other efficacy outcomes (PASI 75 and Physician Global Assessment (PGA) 0/1), the results were similar to the results for PASI 90. Information on quality of life was often poorly reported and was absent for several of the interventions.

AUTHORS' CONCLUSIONS

Our review shows that, compared to placebo, the biologics infliximab, bimekizumab, ixekizumab, and risankizumab were the most effective treatments for achieving PASI 90 in people with moderate-to-severe psoriasis on the basis of high-certainty evidence. This NMA evidence is limited to induction therapy (outcomes measured from 8 to 24 weeks after randomisation), and is not sufficient for evaluating longer-term outcomes in this chronic disease. Moreover, we found low numbers of studies for some of the interventions, and the young age (mean 44.6 years) and high level of disease severity (PASI 20.4 at baseline) may not be typical of patients seen in daily clinical practice. We found no significant difference in the assessed interventions and placebo in terms of SAEs, and the safety evidence for most interventions was very low to moderate quality. More randomised trials directly comparing active agents are needed, and these should include systematic subgroup analyses (sex, age, ethnicity, comorbidities, psoriatic arthritis). To provide long-term information on the safety of treatments included in this review, an evaluation of non-randomised studies is needed. Editorial note: This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available.

Secondary immunodeficiencies and infectious considerations of biologic immunomodulatory therapies

Biologic immunomodulatory medications have rapidly expanded in the previous decades, providing new treatment options for individuals with a spectrum of oncologic, allergic, rheumatologic, and neurologic conditions. Biologic therapies alter immune function and can impair key host defense mechanisms, resulting in secondary immunodeficiency and increased infectious risks. Biologic medications can increase general risk for upper respiratory tract infections but can also be associated with unique infectious risks owing to distinct mechanisms of action. With the widespread use of these medications, providers in every area of medicine will likely care for individuals receiving biologic therapies and understanding their potential infectious complications can help mitigate these risks. This practical review discusses the infectious implications of biologics by class of medication and provides recommendations regarding the examination and screening both before therapy initiation and while the patient is receiving the medication. With this knowledge and background, providers can reduce risk whereas patients receive the treatment benefits of these biologic medications.

Identification immune response genes in psoriasis after treatment with secukinumab

BACKGROUND

Secukinumab is a fully human IgG1κ MoAb that selectively binds to IL-17A with high affinity, and it has been proven effective for the treatment of psoriasis. However, the immune response pathways and mechanisms during the treatment are still masked. Therefore, the current study was designed to investigate the potential immune response genes via bioinformatics approaches.

METHODS

Gene expression data of severe plaque-type psoriasis was retrieved from the GEO database. Quantification of immune infiltration by ssGSEA and identification of differentially infiltrated immune cells were conducted to validate the treatment effect of secukinumab. After data processing, differentially expressed genes were identified between the treatment and untreated group. TC-seq was employed to analyze the trend of gene expression and clustering analysis. IL-17 therapeutic immune response genes were selected by taking the intersection of the genes inside the key cluster set and the MAD3-PSO geneset. Based on these therapeutic response genes, protein-protein interaction networks were built for key hub gene selection. These hub genes would work as potential immune response genes, and be validated via an external dataset.

RESULTS

Enrichment scores calculated by ssGSEA illustrated that the immune infiltration level of T cells had a strong difference before and after medication, which validated the treatment effect of Secukinumab. 1525 genes that have significantly different expression patterns before and after treatment were extracted for further analysis, and the enrichment result shows that these genes have the function related to epidermal development, differentiation, and keratinocytes differentiation. After overlapping candidate genes with MAD3-PSO gene set, 695 genes were defined as anti-IL7A treatment immune response genes, which were mainly enriched in receptor signaling and IL-17 signaling pathways. Hub gene were pinpointed from the PPI network constructed by anti-IL7A treatment immune response genes, their expression pattern fits TC-seq gene expression pattern.

CONCLUSION

Our study revealed the potential anti-IL7A treatment immune response genes, and the central hub genes, which may act critical roles in Secukinumab, induced immune response. This would open up a novel and effective avenue for the treatment of psoriasis.

Secukinumab long-term efficacy and safety in psoriasis through to year 5 of treatment: results of a randomized extension of the phase III ERASURE and FIXTURE trials

BACKGROUND

In the long-term extension study of the ERASURE and FIXTURE trials, the efficacy of secukinumab (a fully human anti-interleukin-17A monoclonal antibody) was demonstrated to have been maintained through to year 3 of treatment in moderate-to-severe plaque psoriasis.

OBJECTIVES

To assess the efficacy and safety of secukinumab through to year 5 of treatment in moderate-to-severe plaque psoriasis.

METHODS

Responders with ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) from two core trials - ERASURE and FIXTURE - were randomized 2 : 1 at year 1 (end of core trials) to either the same dose (300 or 150 mg, continuous treatment) or placebo (treatment withdrawal) every 4 weeks, until year 3 or relapse (> 50% reduction in maximal PASI from core study baseline). Partial responders (achieving PASI 50 but not PASI 75) at year 1 continued at the same dose as in the core trials. At year 3, all patients received open-label secukinumab treatment, with those on secukinumab 300 mg continuing on their dose, while those on secukinumab 150 mg or placebo received secukinumab 150 or 300 mg based on the physician's discretion. The study is registered on ClinicalTrials.gov with the identifier NCT01544595.

RESULTS

Most patients randomized to placebo at year 1 relapsed, but the response was rapidly recaptured upon reinitiation of treatment. PASI responses were sustained with secukinumab through to year 5. The PASI responses for the 300 mg responders + partial responders group at year 1 (PASI 75/90/100: 86.8%/72.8%/45.9%) trended downwards until year 3 (PASI 75/90/100: 82.3%/58.4%/32.7%) and then remained stable through year 4 (PASI 75/90/100: 83.3%/60.1%/32.2%) until year 5 (PASI 75/90/100: 81.1%/62.8%/35.1%). Dermatology Life Quality Index showed sustained benefit up to year 5. Absolute PASI responses were maintained throughout the study. The most common adverse events (AEs) were infections and infestations, nasopharyngitis, and upper respiratory tract infections (URTIs). The overall exposure-adjusted incidence rate (EAIR; with 95% confidence interval) for all AEs was 139.9 (130.3-149.9). EAIRs for Crohn's disease and neutropenia were 0.1 (0.0-0.3) and 0.5 (0.3-0.8), respectively.

CONCLUSIONS

The 4-year extension of two pivotal phase III trials demonstrated that secukinumab treatment was effective through to year 5 and improved quality of life in patients with moderate-to-severe plaque psoriasis. The most common AEs were infections and infestations, nasopharyngitis, and URTIs. The safety profile was consistent with that in the secukinumab phase II/III clinical development programme.

English version of Japanese guidance for use of biologics for psoriasis (the 2022 version)

This is the English version of Japanese guidance for use of biologics for psoriasis (the 2022 version). As the first biologics for psoriasis in Japan, infliximab and adalimumab, anti-tumor necrosis factor-α antibodies, became available in the field of dermatology in 2010, followed by ustekinumab, an anti-interleukin (IL)-12/IL-23p40 antibody, which was launched in Japan in 2011. Moreover, after 2015, three IL-17 inhibitors, the IL-17A antibody preparations secukinumab and ixekizumab, and an anti-IL-17 receptor antibody preparation brodalumab were marketed. Furthermore, after 2018, the anti-IL23p19 antibody preparations guselkumab and risankizumab, the TNF inhibitor certolizumab pegol, the IL-23 inhibitor tildrakizumab, and the anti-IL-17A/F antibody bimekizumab were marketed. It is important for physicians to select appropriate biologic therapy for each psoriatic patient after due consideration of disease factors, treatment factors, and patient background factors, sharing such information with patients. The followings can be listed as points to be considered for the selection of biologics: drug effects (e.g., strength of effectiveness, time to onset of effectiveness, effectiveness against arthritis, primary failure, secondary failure), safety (e.g., infections, administration-related reactions, and relationships with other comorbidities), convenience for patients (e.g., hospital visit intervals, self-injection, maintenance therapy at clinics, feasibility of drug discontinuation/re-administration), and payment (medical costs) borne by patients. This guidance has been prepared with the aim of allowing dermatologists experienced in the treatment of psoriasis to use biologics appropriately according to the circumstances of individual patients after consideration of the above-mentioned factors.

Psoriasis improvements and inflammatory biomarker normalization with secukinumab: the randomized ObePso-S study

BACKGROUND

The IL-17A inhibitor secukinumab has demonstrated consistent efficacy and safety in patients with moderate-to-severe plaque psoriasis, with normalization of molecular and histopathologic psoriasis markers.

OBJECTIVE

To investigate treatment effects of secukinumab on clinical signs and psoriatic inflammation markers over 52 weeks in patients with psoriasis.

METHODS

In the ObePso-S study (NCT03055494), patients with psoriasis were randomized 2:1 to receive secukinumab 300 mg (n = 54) or placebo (n = 28), stratified by body weight (<90 or ≥90 kg), for 52 weeks. At Week 12, patients receiving placebo were switched to secukinumab. Psoriasis Area and Severity Index improvement of 90% (PASI90) and Investigator's Global Assessment modified 2011 0/1 responses were assessed at Weeks 12 and 52. Immunohistochemistry for keratin 16 (K16) and gene expression profiles were evaluated in lesional and non-lesional skin biopsies collected at baseline, Week 12, and Week 52.

RESULTS

Of patients receiving secukinumab, 55.8% and 59.6% achieved PASI90 at Weeks 12 and 52, respectively. K16 was absent in 93.1% of Week 12 PASI90 responders and 93.6% of Week 52 PASI90 responders, which mirrored the down-regulated expression of psoriatic inflammation. Week 52 PASI90 non-responders experienced regression of clinical and inflammatory marker responses toward baseline levels. Lower control of inflammatory gene expression at Week 12 was associated with suboptimal clinical responses at Week 52.

CONCLUSION

Sustained clinical responses with secukinumab were associated with rapid and sustained normalization of K16 and inflammatory gene expression in most patients. Molecular anti-inflammatory effects of secukinumab at Week 12 were associated with clinical responses at Week 52.

Secukinumab demonstrates superiority over narrow-band ultraviolet B phototherapy in new-onset moderate to severe plaque psoriasis patients: Week 52 results from the STEPIn study

BACKGROUND

Biologic treatments have been studied mainly in patients with a long-term history of psoriasis and previous treatment failures.

OBJECTIVES

The purpose of this primary analysis of the STEPIn study is to determine whether early intervention with secukinumab in patients with new-onset moderate to severe plaque psoriasis is superior to standard of care treatment with narrow band ultraviolet B (nb-UVB) phototherapy.

METHODS

The STEPIn study is a randomized, open-label, multicentre study to investigate early intervention with 52 weeks of secukinumab 300 mg administered subcutaneously versus standard treatment with nb-UVB phototherapy in patients with new-onset (≤12 months) moderate to severe plaque psoriasis (NCT03020199). The primary and additional secondary endpoints were ≥90% improvement in Psoriasis Area and Severity Index (PASI 90) at Week 52 and Investigator's Global Assessment (IGA mod 2011) 0/1 response at Week 52, respectively.

RESULTS

In the secukinumab and nb-UVB study arms, 77/80 and 76/80 randomized patients received at least one dose of study treatment, respectively. The primary endpoint was achieved: 91.1% (70/77) of patients achieved a PASI 90 response at Week 52 in the secukinumab arm versus 42.3% (32/76) in the nb-UVB arm (p < 0.0001, odds ratio [OR] estimate [95% confidence intervals, CI] = 16.3 [5.6, 46.9]). The additional secondary endpoint was also achieved: 85.7% of patients achieved an IGA 0/1 response at Week 52 in the secukinumab arm versus 36.8% in the nb-UVB arm (p < 0.0001). The safety data were consistent with the safety profiles of secukinumab and nb-UVB with no new or unexpected safety signals.

CONCLUSIONS

Secukinumab was superior to nb-UVB in treating patients with new-onset moderate to severe plaque psoriasis. The high and sustained skin clearance observed indicates that biologic treatment for psoriasis may be more effective if used early in the disease course.

Efficacy of Secukinumab in Psoriasis: Post Hoc Gender-Wise Analysis of the SUPREME Study

Purpose

Psoriasis, a common systemic inflammatory disorder, presents with gender-related differences in the quality of life (QoL) and treatment outcomes. This post hoc analysis from the Phase 3b SUPREME study explored gender-related differences in patient characteristics and efficacy of secukinumab 300 mg on Psoriasis Area and Severity Index (PASI) 75/90/100 and impact on QoL using the Dermatology Life Quality Index (DLQI) in patients with moderate to severe psoriasis through week 24.

Patients and Methods

The proportion of patients achieving PASI 75/90/100 was computed using a nonresponder imputation approach. Differences between cohorts were analyzed using a logistic regression model. The mean change from baseline in DLQI was computed using the Wilcoxon test.

Results

Among the 433 patients (males: 71.6%), females had a higher DLQI than males at baseline (13.1 vs 9.5; P<0.0001). Males had a slightly higher response for PASI 90 than females at week 16 (80.7% vs 78.1%; P=0.0779) and 24 (83.2% vs 79.7%; P=0.0319). No differences were observed between genders in PASI 100/75 responses at week 24. Both genders showed an improvement in DLQI with secukinumab at week 24 (-10.9 vs -8.1, respectively, in females vs males; P=0.0004).

Conclusion

In summary, secukinumab was effective in the treatment of psoriasis, irrespective of gender.

Effectiveness and Safety of Secukinumab in Latin American Patients with Moderate to Severe Plaque Psoriasis: PURE Registry 12-Month Data

BACKGROUND

 The efficacy and safety of secukinumab in patients with psoriasis has been established in randomised clinical trials. However, data on effectiveness and safety of secukinumab in Latin American real-world settings are scarce.

OBJECTIVES

To evaluate the effectiveness and safety of secukinumab in real-world settings in patients with psoriasis in Latin America.

METHODS

PURE is an ongoing multinational, prospective, observational study in patients with moderate-to-severe chronic plaque psoriasis in Canada and Latin America assessing the real-world safety and effectiveness of secukinumab and other approved therapies. The study enrolled (1:1) patients treated with secukinumab versus other approved therapies (other Tx) per local standard of care from 81 community- and hospital-based speciality sites (21 in Latin America). Here, we report effectiveness and safety outcomes with secukinumab and other Tx for plaque psoriasis for up to 12 months in a Latin American population.

RESULTS

Overall, 187 patients were included in the analysis, 89 of whom initiated secukinumab treatment and 98 of whom received other Tx. At month 12, 84.4%, 71.1% and 53.3% of patients treated with secukinumab achieved Psoriasis Area and Severity Index (PASI) 75/90/100, respectively, compared with 66.7%, 47.9% and 29.2% of patients who received other Tx. Investigator Global Assessment (IGA) 0/1 responders in secukinumab versus other Tx were 78.3% versus 36.7% at month 3 and 81.8% versus 66.7% at month 12, respectively. Overall, the proportion of patients achieving Dermatology Life Quality Index (DLQI) 0/1 improved from 6.9% at baseline to 76.5% at month 12 in patients treated with secukinumab versus 5.6% at baseline to 54.5% at month 12 in patients on other Tx. No unexpected adverse events were reported during the 12-month observation period.

CONCLUSION

Secukinumab demonstrated real-world effectiveness and improved dermatology quality-of-life in chronic plaque psoriasis patients from Latin America.

Should we be concerned about gastrointestinal-related adverse events in patients with plaque psoriasis receiving secukinumab therapy? A retrospective, real-life study

Real-world secukinumab gastrointestinal-related adverse events (GIRAE) data in psoriatic patients treated with secukinumab are lacking. A descriptive, retrospective study was performed by reviewing the medical records of patients who received secukinumab for plaque psoriasis for at least 1 year and who made a follow-up visit to the dermatology clinic of "Ospedali Riuniti Umberto I" in Ancona between December 1, 2021, and March 31, 2022. The patients' medical history and clinical data were collected at T0, before treatment, and at T1, corresponding to the last follow-up visit. Special attention was given to gastrointestinal adverse events (GIRAE). A total of 108 patients were included in the study. At baseline median PASI was 14.8 (range 2.2-27, SD 6.1), and median DLQI was 9.3 (5-16, SD 2.6). The median PASI for treated patients was 0.7 (0-3, SD 0.8; p < 0.00) 1and median DLQI was 0.3 (0-1, SD 0.5; p < 0.001). At T1 54/114 patients (50%) reached PASI100, of the other 54, 48 (88.9%) reached PASI 90 while the other six discontinued for secondary ineffectiveness. Only three patients reported a GIRAE (diarrhea), however, when screened, no IBD was found. Consistent with data in the literature, secukinumab is an effective and safe drug for the treatment of plaque psoriasis also in a real-life experience context. There should be no concern in choosing the drug for fear of possible IBDs-related GIRAE if there is no personal history or familiarity for IBDs.

Risk of COVID-19 infection, hospitalization and mortality in psoriasis patients treated with interleukin-17 inhibitors: A systematic review and meta-analysis

BACKGROUND

Coronavirus disease 2019 (COVID-19) have brought great disaster to mankind, and there is currently no globally recognized specific drug or treatment. Severe COVID-19 may trigger a cytokine storm, manifested by increased levels of cytokines including interleukin-17 (IL-17), so a new strategy to treat COVID-19 may be to use existing IL-17 inhibitors, which have demonstrated efficacy, safety and tolerability in the treatment of psoriasis. However, the use of IL-17 inhibitors in patients with psoriasis during the COVID-19 pandemic remains controversial due to reports that IL-17 inhibitors may increase the risk of respiratory tract infections.

OBJECTIVES

The systematic review and meta-analysis aimed to evaluate the effect of IL-17 inhibitors on the risk of COVID-19 infection, hospitalization, and mortality in patients with psoriasis.

METHODS

Databases (including Embase, PubMed, SCI-Web of Science, Scopus, CNKI, and the Cochrane Library) were searched up to August 23, 2022, for studies exploring differences in COVID-19 outcomes between psoriasis patients using IL-17 inhibitors and those using non-biologics. Two authors independently extracted data and assessed the risk of bias in a double-blind manner. The risk ratios (RRs) and 95% confidence intervals (CIs) were calculated and heterogeneities were determined by the Q test and I 2 statistic. And the numbers needed to treat (NNTs) were calculated to assess the clinical value of IL-17 inhibitors in preventing SARS-CoV-2 infection and treating COVID-19.

RESULTS

Nine observational studies involving 7,106 participants were included. The pooled effect showed no significant differences in the rates of SARS-CoV-2 infection (P = 0.94; I 2 = 19.5%), COVID-19 hospitalization (P = 0.64; I 2 = 0.0%), and COVID-19 mortality (P = 0.32; I 2 = 0.0%) in psoriasis patients using IL-17 inhibitors compared with using non-biologics. Subgroup analyses grouped by age and COVID-19 cases, respectively, revealed consistent results as above. Meanwhile, the pooled NNTs showed no significant differences between the two groups in the clinical value of preventing SARS-CoV-2 infection and treating COVID-19.

CONCLUSION

The use of IL-17 inhibitors in patients with psoriasis does not increase the risk of SARS-CoV-2 infection or worsen the course of COVID-19.

Available Alternative Biologics and Disease Groups Influence Biologic Drug Survival in Patients with Psoriasis and Psoriatic Arthritis

BACKGROUND

Factors other than efficacy and safety could influence the survival of biologics in patients with psoriasis. Little is known about whether different disease groups affect drug survival of biologics or not.

OBJECTIVE

This study aimed to investigate whether the availability of alternative biologics and disease groups could influence drug survival of biologics approved for psoriasis and psoriasis arthritis (PsA).

METHODS

A nationwide population-based retrospective cohort study was conducted using the Health Insurance and Review Assessment data in Korea between January 2009 and August 2019.

RESULTS

The drug survival analysis included 5,634 biologic episodes. Ustekinumab was the most frequently prescribed drug (n=2,488, 44.2%). Multivariable time-dependent Cox regression analysis showed that higher age, female sex, no comorbidity, concomitant cyclosporine or acitretin use, biologic-experienced and use of tumor necrosis factor (TNF)-α inhibitors were predictors of drug discontinuation. PsA was a predictor of drug persistence, particularly for TNF-α inhibitors. Ustekinumab and adalimumab discontinuation significantly increased after introducing secukinumab and ustekinumab, respectively.

CONCLUSION

The availability of alternative biologics and disease groups affect biologic drug survival in patients with psoriasis and PsA.

Invasive aspergillus infection of middle ear in a patient treated with secukinumab, methotrexate and corticosteroids for psoriasis and psoriatic arthritis

Mucocutaneous mycotic infections are common complications in patients on IL-17 inhibitor therapy. We report a case of a 33-year-old male with severe psoriasis and psoriatic arthritis on secukinumab combined with methotrexate and prednisone with swelling, otorrhoea and pain of the right ear and external auditory canal. Because of progressive hypacusis, a surgical solution was chosen. Tissue samples taken during surgery revealed the presence of Aspergillus fumigatus. Aspergillosis should be suspected in prolonged otorrhoea, especially in immunocompromised patients. Without intervention, the disease could be fatal.

Secukinumab treatment showed improved quality of life in patients with chronic plaque psoriasis in Australia: Results from the HOPE study

BACKGROUND

Psoriasis imposes a disease burden that can have a profound negative impact on patients' quality of life (QoL). HOPE was the first non-interventional study conducted in patients with severe chronic plaque psoriasis in Australia that evaluated health-related QoL in response to treatment with secukinumab.

METHODS

HOPE was a prospective, open-label, single-arm, multicentre, non-interventional, exploratory study in patients with severe chronic plaque psoriasis in Australia. The study investigated the change in QoL, using the Dermatology Life Quality Index (DLQI), Assessment Quality of Life-8 Dimension questionnaire (AQoL-8D) and Psoriasis Area and Severity Index (PASI), and safety profile in response to treatment with secukinumab 300 mg SC weekly for 4 weeks followed by monthly maintenance for 58 weeks.

RESULTS

At Week 14, the mean percentage reduction in total DLQI score from baseline was -82.4% (n = 65), which indicates a substantial improvement in QoL. This level of improvement was sustained up to Week ≥58, with a mean percentage change of -87.4%. The mean percentage change from baseline for AQoL-8D weighted total score decreased from Week 14 (41.1%) to Week 58 (35.2%), indicating an improvement in patients' QoL. A high proportion of patients achieved PASI 75/90/100 responses at Week 14 (97.0%/71.2%/34.8%), with rates sustained up to Week ≥58 (100%/87.9%/43.1%). The safety profile of secukinumab was favourable, with no cumulative or unexpected safety concerns.

CONCLUSION

Secukinumab treatment demonstrated a striking improvement in patients' QoL in the HOPE study, the first real-world study in patients with severe chronic plaque psoriasis in the Australian clinical setting.

Secukinumab treatment demonstrated high drug survival and sustained effectiveness in patients with severe chronic plaque psoriasis: 21-month analysis in Australian routine clinical practice (SUSTAIN study)

BACKGROUND

Drug survival measures the rate and duration of adherence to a given therapeutic agent and evaluates its long-term effectiveness, safety, and real-world utility. The SUSTAIN study sought to establish the drug survival and effectiveness of secukinumab for patients with severe chronic plaque psoriasis (CPP) in the Australian clinical setting.

METHODS

Data of all patients (aged ≥18 years) from Australasian Psoriasis Registry (APR) treated with secukinumab were analysed. The primary objective was to describe the drug survival of secukinumab at 9 months. Key secondary objectives included drug survival of secukinumab at 3, 6, 15, and 21 months, stratified by biologic-naïve vs biologic-experienced patients; proportion of patients achieving Psoriasis Area and Severity Index (PASI) 75/90/100 responses; and changes in health-related quality of life over time utilising the Dermatology Life Quality Index (DLQI).

RESULTS

Of 294 patients included in this analysis, 110 (37.4%) were biologic-naïve and 184 (62.6%) biologic-experienced. Kaplan-Meїer drug survival rates in biologic-naïve vs biologic-experienced patients were 0.92 vs. 0.86 (9 months) and 0.82 vs. 0.68 (21 months), respectively. The proportion of patients with PASI 75/90/100 responses for biologic-naïve vs. biologic-experienced was 100/87.7/38.4 vs 98.5/61.5/27.2 (9 months) and 100/81.0/41.7 vs. 98.4/62.0/24.2 (21 months), respectively. The mean (standard deviation [SD]) DLQI in biologic-naïve vs. experienced patients was 2.2 (4.1) vs. 3.1 (5.2) (9 months) and 1.4 (2.5) vs. 3.1 (5.3) (21 months). No new safety signals were observed.

CONCLUSIONS

Secukinumab demonstrated high drug survival and sustained effectiveness in Australian real-world setting, in biologic-naïve and biologic-experienced patients with severe CPP.

Therapeutic effects of the extract of Sancao Formula, a Chinese herbal compound, on imiquimod-induced psoriasis via cysteine-rich protein 61

OBJECTIVE

Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis.

METHODS

The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses.

RESULTS

Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1.

CONCLUSION

The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

Secukinumab demonstrated sustained retention, effectiveness and safety in a real-world setting in patients with moderate to severe plaque psoriasis: long-term results from an interim analysis of the SERENA study

BACKGROUND

Randomised controlled trials of secukinumab have shown sustained efficacy and a favourable safety profile in multiple manifestations of psoriatic disease.

OBJECTIVES

To assess the long-term, real-world retention, effectiveness, and safety of secukinumab in routine clinical practice for the treatment of moderate to severe plaque-type psoriasis (PsO).

METHODS

SERENA (CAIN457A3403) is a large, ongoing, longitudinal, observational study conducted at 438 sites and 19 countries across Europe for an expected duration of up to 5 years in adult patients with moderate to severe PsO, psoriatic arthritis, and ankylosing spondylitis. Patients received ≥16 weeks of secukinumab treatment before enrolment. This interim analysis presents data from PsO patients, who were enrolled in the study between October-2016-October-2018 and were observed for ≥2 years.

RESULTS

In total, 1756 patients (67.3% male) with a mean age of 48.4 years and body mass index of 28.8 kg/m² were included in the analysis. The secukinumab treatment retention rates after 1, 2 and 3 years in the study were 88.0%, 76.4% and 60.5%, respectively. Out of the 648 patients who discontinued the study, the most common reasons included lack of efficacy (42.6%), adverse event (17.4%), physician decision (12.2%) and subject decision (11.6%). Mean±SD absolute PASI was 21.0±13.0 at the start of treatment (n=1,564). At Baseline, the mean±SD PASI score reduced to 2.6±4.8 and remained low at Year 1 (2.3±4.3), Year 2 (1.9±3.6) and Year 3 (1.9±3.5). The safety profile of secukinumab during the SERENA study was consistent with its known safety profile, with no new safety signals reported. Particularly low rates of inflammatory bowel disease (0.3%; Incidence Rate [IR]:0.15), candida infections (3.1%; IR:1.43) and MACE (0.9%; IR:0.37) were observed.

CONCLUSIONS

Secukinumab showed high treatment persistence, sustained effectiveness and a favourable safety profile up to 3 years of follow-up in the real-world population of PsO patients observed in SERENA.

Systemic pharmacological treatments for chronic plaque psoriasis: a network meta-analysis

BACKGROUND

Psoriasis is an immune-mediated disease with either skin or joints manifestations, or both, and it has a major impact on quality of life. Although there is currently no cure for psoriasis, various treatment strategies allow sustained control of disease signs and symptoms. The relative benefit of these treatments remains unclear due to the limited number of trials comparing them directly head-to-head, which is why we chose to conduct a network meta-analysis.

OBJECTIVES

To compare the efficacy and safety of non-biological systemic agents, small molecules, and biologics for people with moderate-to-severe psoriasis using a network meta-analysis, and to provide a ranking of these treatments according to their efficacy and safety.

SEARCH METHODS

For this update of the living systematic review, we updated our searches of the following databases monthly to October 2021: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of systemic treatments in adults over 18 years with moderate-to-severe plaque psoriasis, at any stage of treatment, compared to placebo or another active agent. The primary outcomes were: proportion of participants who achieved clear or almost clear skin, that is, at least Psoriasis Area and Severity Index (PASI) 90; proportion of participants with serious adverse events (SAEs) at induction phase (8 to 24 weeks after randomisation).

DATA COLLECTION AND ANALYSIS

We conducted duplicate study selection, data extraction, risk of bias assessment and analyses. We synthesised data using pairwise and network meta-analysis (NMA) to compare treatments and rank them according to effectiveness (PASI 90 score) and acceptability (inverse of SAEs). We assessed the certainty of NMA evidence for the two primary outcomes and all comparisons using CINeMA, as very low, low, moderate, or high. We contacted study authors when data were unclear or missing. We used the surface under the cumulative ranking curve (SUCRA) to infer treatment hierarchy, from 0% (worst for effectiveness or safety) to 100% (best for effectiveness or safety).

MAIN RESULTS

This update includes an additional 19 studies, taking the total number of included studies to 167, and randomised participants to 58,912, 67.2% men, mainly recruited from hospitals. Average age was 44.5 years, mean PASI score at baseline was 20.4 (range: 9.5 to 39). Most studies were placebo-controlled (57%). We assessed a total of 20 treatments. Most (140) trials were multicentric (two to 231 centres). One-third of the studies (57/167) had high risk of bias; 23 unclear risk, and most (87) low risk. Most studies (127/167) declared funding by a pharmaceutical company, and 24 studies did not report a funding source. Network meta-analysis at class level showed that all interventions (non-biological systemic agents, small molecules, and biological treatments) showed a higher proportion of patients reaching PASI 90 than placebo. Anti-IL17 treatment showed a higher proportion of patients reaching PASI 90 compared to all the interventions, except anti-IL23. Biologic treatments anti-IL17, anti-IL12/23, anti-IL23 and anti-TNF alpha showed a higher proportion of patients reaching PASI 90 than the non-biological systemic agents. For reaching PASI 90, the most effective drugs when compared to placebo were (SUCRA rank order, all high-certainty evidence): infliximab (risk ratio (RR) 50.19, 95% CI 20.92 to 120.45), bimekizumab (RR 30.27, 95% CI 25.45 to 36.01), ixekizumab (RR 30.19, 95% CI 25.38 to 35.93), risankizumab (RR 28.75, 95% CI 24.03 to 34.39). Clinical effectiveness of these drugs was similar when compared against each other. Bimekizumab, ixekizumab and risankizumab showed a higher proportion of patients reaching PASI 90 than other anti-IL17 drugs (secukinumab and brodalumab) and guselkumab. Infliximab, anti-IL17 drugs (bimekizumab, ixekizumab, secukinumab and brodalumab) and anti-IL23 drugs (risankizumab and guselkumab) except tildrakizumab showed a higher proportion of patients reaching PASI 90 than ustekinumab and three anti-TNF alpha agents (adalimumab, certolizumab and etanercept). Ustekinumab was superior to certolizumab; adalimumab and ustekinumab were superior to etanercept. No significant difference was shown between apremilast and two non-biological drugs: ciclosporin and methotrexate. We found no significant difference between any of the interventions and the placebo for the risk of SAEs. The risk of SAEs was significantly lower for participants on methotrexate compared with most of the interventions. Nevertheless, the SAE analyses were based on a very low number of events with low- to moderate-certainty for all the comparisons (except methotrexate versus placebo, which was high-certainty). The findings therefore have to be viewed with caution. For other efficacy outcomes (PASI 75 and Physician Global Assessment (PGA) 0/1), the results were similar to the results for PASI 90. Information on quality of life was often poorly reported and was absent for several of the interventions.

AUTHORS' CONCLUSIONS

Our review shows that, compared to placebo, the biologics infliximab, bimekizumab, ixekizumab, and risankizumab were the most effective treatments for achieving PASI 90 in people with moderate-to-severe psoriasis on the basis of high-certainty evidence. This NMA evidence is limited to induction therapy (outcomes measured from 8 to 24 weeks after randomisation), and is not sufficient for evaluating longer-term outcomes in this chronic disease. Moreover, we found low numbers of studies for some of the interventions, and the young age (mean 44.5 years) and high level of disease severity (PASI 20.4 at baseline) may not be typical of patients seen in daily clinical practice. We found no significant difference in the assessed interventions and placebo in terms of SAEs, and the safety evidence for most interventions was low to moderate quality. More randomised trials directly comparing active agents are needed, and these should include systematic subgroup analyses (sex, age, ethnicity, comorbidities, psoriatic arthritis). To provide long-term information on the safety of treatments included in this review, an evaluation of non-randomised studies and postmarketing reports from regulatory agencies is needed. Editorial note: This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available. Please refer to the Cochrane Database of Systematic Reviews for the current status of this review.

Persistence, effectiveness, and real-world outcomes in psoriasis patients treated with secukinumab in Portugal

AIMS

To characterize moderate to severe psoriasis (PsO) adult patients treated with secukinumab, estimate drug persistence and assess any reasons for treatment discontinuation.

METHODS

Non-interventional, retrospective, longitudinal record-based study including patients diagnosed with PsO who started secukinumab between January 2018 and January 2020. Baseline characteristics were analysed by descriptive statistics; drug persistence and predictive factors were assessed through Kaplan-Meier curves and univariate and multivariate analysis, respectively.

RESULTS

A total of 302 patients were included in the study: mean age was 48.4 years, 41.7% were female, median time since diagnosis was 12.9 years. 51.3% of patients were bio-naïve while 48.7% had previously been treated with biologics. PsO in difficult-to-treat locations (DTL) was present in 82.1% of patients, with scalp PsO in about half of patients. At 5-years follow-up, 84 patients discontinued secukinumab, 45 of which due to loss of efficacy. At week 104, overall treatment persistence was 71.7%. A higher probability of drug persistence was identified among those patients who initiated secukinumab ≥5 years after diagnosis, were bio-naïve or treated with only one previous biologic, had no PsO on DTL, and had diabetes mellitus. The predictive factors for discontinuation identified in our study were the start of secukinumab <5 years after diagnosis (p=.001), the bio-experimented status with ≥2 biologics (p=.007), and the presence of PsO on DTL (p=.014).

CONCLUSIONS

A time since diagnosis of ≥5 years, naïve status or previous use of only one biologic are predictors for secukinumab persistence, whereas the presence of PsO on DTL predicts drug discontinuation.

Lack of reactivation of tuberculosis in patients with psoriasis treated with secukinumab in a real-world setting of latent tuberculosis infection

BACKGROUND

Some biologics for psoriasis, especially anti-tumor necrosis factor (TNF)-α therapies, may re-activate latent tuberculosis (TBC) infection with consequent morbidity and mortality. However, there is a low reported incidence of conversion to positive TBC status among patients with psoriasis treated with second-generation biologic therapies, particularly anti-interleukin (IL)-17 therapies such as secukinumab.

OBJECTIVES

To evaluate the safety profile of secukinumab in psoriasis patients with latent TBC infection.

METHODS

Real-life data were collected by retrospective chart review on patients with moderate-to-severe psoriasis who showed positivity for TBC screening at baseline and underwent secukinumab treatment for psoriasis at six Italian centers. Patients received secukinumab 300 mg at week 0/1/2/3/4, then every 4 weeks.

RESULTS

Fifty-nine patients were enrolled; 30.5% also had psoriatic arthritis and other comorbidities were common. At baseline, the mean psoriasis duration was 14.5 years. Ten (17%) patients did not undergo prophylaxis before starting secukinumab. Conversely, isoniazid ± rifampicin or rifampicin alone prophylaxis was administered in 49/59 (83.1%) patients. After a mean treatment duration of 84 weeks, there were no cases of TBC reactivation and no unexpected safety signals.

CONCLUSIONS

Secukinumab use over an extended period was safe in psoriasis patients with latent TBC, even in patients who did not receive chemoprophylaxis.

Anti-rheumatic drug-induced hepatitis B virus reactivation and preventive strategies for hepatocellular carcinoma

To date, an estimated 3 million people worldwide have been infected with chronic hepatitis B virus (HBV). Although anti-HBV therapies have improved the long-term survival profile of chronic carriers, viral reactivation still poses a significant challenge for preventing HBV-related hepatitis, hepatocellular carcinoma (HCC), and death. Immuno-modulating drugs, which are widely applied in managing rheumatic conditions, are commonly associated with HBV reactivation (HBVr) as a result of drug-induced immune suppression. However, there are few reports on the risk of HBVr and the medication management plan for HBV carriers, especially rheumatic patients. In this review, we summarize immuno-modulating drug-induced HBVr during rheumatoid therapy and its preventive strategies for HBVr-induced liver diseases, especially cirrhosis and HCC. These findings will assist with developing treatments for rheumatic patients, and prevent HBV-related cirrhosis and HCC.

Therapeutic drug monitoring in dermatology: the way towards dose optimization of secukinumab in chronic plaque psoriasis

Background

Despite the favourable efficacy profile of secukinumab, clinicians encounter varying clinical responses among patients potentially associated with under‐ and overdosing. As biologics are expensive, their rational use is crucial and evident. Therapeutic drug monitoring could guide clinicians in making decisions about treatment modifications.

Aim

In this multicentre, prospective study, we aimed to develop and validate a secukinumab immunoassay and searched for the therapeutic window in patients with psoriasis.

Methods

We determined secukinumab concentrations at trough in sera from 78 patients with psoriasis at multiple timepoints (Weeks 12, 24, 36, 48 and 52; after Week 52, measurements could be taken at an additional three timepoints) during maintenance phase, using an in‐house secukinumab immunoassay consisting of a combination of MA‐SEC66A2 as capture antibody and MA‐SEC67A9, conjugated to horseradish peroxidase, as detecting antibody. At each hospital visit, disease severity was assessed using the Psoriasis Area and Severity Index (PASI).

Results

After quantification, 121 serum samples were included for dose–response analysis. Based on a linear mixed‐effects model, secukinumab trough concentrations were found to decrease with increasing body mass index (BMI). Based on receiver operating characteristic (ROC) analysis, we concluded that the minimal effective secukinumab threshold was 39.1 mg/L in steady state, and that this was associated with a 92.7% probability of having an optimal clinical response (PASI ≤ 2 or reduction in PASI of ≥ 90%).

Conclusions

Monitoring and targeting a secukinumab trough concentration of 39.1 mg/L may be a viable treatment option in suboptimal responders. In patients with higher BMI, weight‐based dosing may be needed in order to prevent underdosing.

The Societal Economic Impact of Secukinumab in First-Line Treatment of Moderate to Severe Plaque Psoriasis in Germany: An Open-Cohort Simulation

OBJECTIVES

Moderate to severe plaque psoriasis is a chronic inflammatory disease. In Germany, guidelines recommend fumaric acid esters (FAEs) as first-line systemic treatment. Despite treatment with FAEs, disease burden remains high in Germany. Secukinumab, a fully human monoclonal antibody, has demonstrated greater efficacy and safety than FAEs in the PRIME trial. The aim of the current study, hence, is to quantify the potential societal economic impact of secukinumab in systemic treatment-naïve patients with moderate to severe plaque psoriasis in Germany.

METHODS

We employed a semi-Markov model to capture health gains at an individual level and a dynamic population model to extrapolate the findings in the population of interest. We quantified the health outcomes in two scenarios: (i) patients receiving secukinumab and (ii) patients receiving FAEs. Using estimates on change in work productivity and societal economic parameters, we translated the health outcomes into paid and unpaid economic gains. We used gross value added (GVA) to value these gains and calculated the macroeconomic indirect and induced value-chain effects.

RESULTS

Our calculations show that patients treated with secukinumab spend on average 94% of their time in Psoriasis Area and Severity Index (PASI) ≥ 75 state compared with 80% for patients in the FAEs scenario. When assuming that FAEs are the sole comparator to secukinumab, this difference could lead to 4.3 million active hours gained until 2030. These gained hours translate to a total societal economic impact of €308 million till 2030 for the whole patient population in GVA terms.

CONCLUSION

This study demonstrated that using secukinumab instead of FAEs in moderate to severe plaque psoriasis could lead to substantial macroeconomic GVA gains.

Practical update of the Recommendations Published by the Psoriasis Group of the Spanish Academy of Dermatology and Venereology (GPS) on the Treatment of Psoriasis with Biologic Therapy. Part 1. Concepts and General Management of Psoriasis with Biologic Therapy

BACKGROUND AND OBJECTIVES

A new, updated AEDV Psoriasis Group consensus document on the treatment of moderate to severe psoriasis was needed owing to the approval, in recent years, of a large number of new drugs and changes in the treatment paradigm.

METHODOLOGY

The consensus document was developed using the nominal group technique and a scoping review. First, a designated coordinator selected a group of Psoriasis Group members for the panel. The coordinator defined the objectives and key points for the document and, with the help of a documentalist, conducted a scoping review of articles in Medline, Embase, and the Cochrane Library up to January 2021. The review included systematic reviews and meta-analyses as well as clinical trials not included in those studies and high-quality real-world studies. National and international clinical practice guidelines and consensus documents on the management of moderate to severe psoriasis were also reviewed. Based on these reviews, the coordinator drew up a set of proposed recommendations, which were then discussed and modified in a nominal group meeting. After several review processes, including external review by other GPs members, the final document was drafted.

RESULTS

The present guidelines include general principles for the treatment of patients with moderate to severe psoriasis and also define treatment goals and criteria for the indication of biologic therapy and the selection of initial and subsequent therapies. Practical issues, such as treatment failure and maintenance of response, are also addressed.

Effectiveness and Safety of Secukinumab for Psoriasis in a Real-World Clinical Setting in the Asia-Pacific and Middle East Regions: Results from the REALIA Study

INTRODUCTION

Secukinumab has demonstrated sustained long-term efficacy with a favourable safety profile in various manifestations of psoriatic disease. We investigated effectiveness and safety of secukinumab, other biologics and conventional systemic therapies in patients with chronic plaque psoriasis in a real-world setting.

METHODS

REALIA was a non-interventional, multicentre, prospective, parallel group study. Eligible patients were ≥ 18 years old with chronic plaque psoriasis commencing a new treatment with a biologic agent or conventional systemic therapies.

RESULTS

At baseline, 541 patients were divided into three cohorts based on treatment initiated: conventional systemics (173), secukinumab (184) and other biologics (184). A significantly higher proportion of patients achieved almost clear to clear skin based on physician's judgement in secukinumab versus conventional systemics at month 3 (64.7% versus 22.8%, P < 0.001) and month 6 (61.8% versus 20.8%, P < 0.001). At month 12, clear to almost clear skin was achieved by 52.1% of the patients in secukinumab versus 35.8% in conventional systemics (P = 0.066). The proportion of patients achieving Psoriasis Area Severity Index (PASI) 90 on conventional systemics, secukinumab and other biologics was 18.8%, 59.7% and 40.0% at month 3 and 35.3%, 60.8% and 50.0% at month 12, respectively. Secukinumab patients showed significantly higher change in PASI total score from baseline versus conventional systemics at month 3 {least squares [LS] mean [standard error (SE)]: -14.49 [0.648] versus -8.48 [1.149], P < 0.001} and numerically higher [LS mean (SE): -13.60 (0.475) versus -10.84 (1.733), P = 0.122] at month 12. The proportion of patients with Dermatology Life Quality Index 0/1 score on conventional systemics, secukinumab and other biologics was 22.6%, 65.0% and 41.6% at month 3 and 32.0%, 63.5% and 41.3% at month 12, respectively. Safety profile was comparable across cohorts.

CONCLUSIONS

Secukinumab is effective and well tolerated in patients with chronic plaque psoriasis in a real-world setting in an Asia-Pacific and Middle East population, and these results are in agreement with clinical outcomes of secukinumab reported in randomised clinical trials.

Novel Therapeutic Approaches to Psoriasis and Risk of Infectious Disease

Psoriasis is a chronic immune-mediated skin and joint disease, with a plethora of comorbidities, characterized by a certain genetic predisposition, and a complex pathogenesis based on the IL-23/IL-17 pathway. There is no doubt that the patients affected by psoriasis are more susceptible to infections as well as that the risk of infection is higher in psoriatic subjects than in the general population. The advent of biotechnological agents on the therapeutic arsenal actually available for the treatment of moderate-to-severe patients, given the fact that the severity of the disease is a predictor of the level of infectious risk, has raised the question of whether these ‘new’ drugs could be considered a safer option and how they can be used in selected cases. Old and newer strategies in cases of chronic infectious conditions are reviewed under the light of clinical trials and other studies present in literature.

Secukinumab Loss of Efficacy Is Perfectly Counteracted by the Introduction of Combination Therapy (Rescue Therapy): Data from a Multicenter Real-Life Study in a Cohort of Italian Psoriatic Patients That Avoided Secukinumab Switching

Since psoriasis (PsO) is a chronic inflammatory disease, patients may experience a drug failure also with very effective drugs (i.e., secukinumab) and, consequently, dermatologists have two therapeutic options: switching or perform a combination therapy (rescue therapy) to save the drug that had decreased its efficacy. At the moment no studies focused on combination/rescue therapy of secukinumab, so we performed a 52-weeks multicenter retrospective observational study that involved 40 subjects with plaque psoriasis that experienced a secondary failure and were treated with combination therapy (ciclosporin (n = 11), MTX (n = 15), NB-UVB (n = 7) and apremilast (n = 7)). After 16 weeks of rescue/combination therapy, PASI and a DLQI varied respectively from 8 [7.0-9.0] and 13 [12.0-15.0], to 3 [2.8-4.0] and 3 [2.0-3.3]), suggesting a significant improvement of daily functionality and quality of life. Results were maintained at 52 weeks. No side effects were experienced during the study. Secukinumab remains a safety and effective drug for PsO patients also in the IL-23 and JAK inhibitors era. The rescue therapy is a valid therapeutic option in case of secukinumab secondary failure.
