Effectiveness and safety of secukinumab in Italian patients with psoriasis: an 84 week, multicenter, retrospective real-world study

Real-world safety and effectiveness of secukinumab in adult patients with moderate to severe plaque psoriasis: results from postmarketing surveillance in Korea

Background

Secukinumab, a fully human monoclonal antibody, was approved in Korea for the treatment of moderate to severe psoriasis in September 2015.

Objectives

To assess the safety and effectiveness of secukinumab in patients with moderate to severe psoriasis in Korea.

Design

Multicenter, real-world, noninterventional study conducted over 6 years.

Methods

Adults with moderate to severe psoriasis were enrolled. Safety was assessed by evaluating adverse events (AEs), treatment-related AEs, and serious AEs (SAEs). Effectiveness was assessed using the change in absolute Psoriasis Area and Severity Index (PASI) score, percentage of patients achieving PASI 75/90/100 and PASI ⩽2; at weeks 12 and 24.

Results

Overall, 829 and 542 patients were included in the safety and effectiveness sets, respectively. AEs, treatment-related AEs, and SAEs occurred in 29.0%, 9.5%, and 4.1% of patients, with incidence rates of 39.43, 12.98, and 5.59 per 100 patient years, respectively. The absolute PASI score decreased from 16.1 ± 7.1 (baseline) to 1.6 ± 2.4 (week 24), with a similar reduction in biologic-naïve (16.4 ± 7.3 to 1.5 ± 2.2) and biologic-experienced (14.8 ± 5.9 to 2.4 ± 3.2) groups. At week 24, PASI 75/90/100 was achieved by 95.1%, 62.4%, and 24.9% of patients. At week 24, PASI 75/90 were higher in biologic-naïve (96.6%/65.8%) than biologic-experienced patients (88.3%/48.6%), whereas PASI 100 was similar in both cohorts (24.1% and 28.6%). A similar trend in PASI ⩽ 2 was observed in both cohorts.

Conclusion

Secukinumab showed sustained effectiveness and favorable safety profile in adult patients with moderate to severe psoriasis in Korea.

Response to Interleukin-17A Inhibitors According to Prior Biologic Exposures: A Danish Nationwide Study

Whether response to an interleukin (IL-17) inhibitor is different in patients with previous exposure to an IL-17 inhibitor compared with patients with exposure to biologics with other cytokine targets remains to be elucidated. Therefore, the aim of this study was to  assess whether previous exposure to an IL-17A inhibitor was associated with worse response than exposure to (an)other biologic(s). All patients in the DERMBIO register treated with an IL-17A inhibitor (secukinumab or ixekizumab) were included. With an absolute Psoriasis Area and Severity Index (PASI) ≤ 2 as response, the proportion of responders treated with IL-17A inhibitors was assessed in patients previously treated with another IL-17A inhibitor and compared with patients with previous exposure to (an)other biologic(s), using a χ2 test. In total, 100, 93 and 83 patients with  previous exposure to an IL-17A inhibitor and 414, 372 and 314 patients with previous exposure to (an) other biologic(s) were assessed after 3, 6 and 12 months, respectively. No differences in the proportion of  patients achieving PASI ≤ 2 were observed between the 2 groups after 3 months (54% vs 57%, p = 0.59), 6months (70% vs 66%, p = 0.42) and 12 months (69% vs 60%, p = 0.14). In conclusion, when treating patients with IL-17A inhibitors the cytokine target of the previous biologic does not appear to affect the  response.

Treatment outcomes of secukinumab in adult patients with moderate-to-severe plaque psoriasis in China: A real-world multicenter retrospective study

Secukinumab is effective in treating patients with moderate-to-severe plaque psoriasis. However, most studies assessing its effectiveness in routine clinical settings in China are mostly single-center studies with a limited sample size. The objective of this study was to assess secukinumab's efficacy, treatment patterns, and characteristics in patients with moderate-to-severe plaque psoriasis. This 24-week, multicenter (n = 5) retrospective study analyzed the data of Chinese adult patients with moderate-to-severe plaque psoriasis who initiated secukinumab treatment between May 2019 and March 2020. The Psoriasis Area and Severity Index (PASI), body surface area (BSA), Investigator's Global Assessment Modified 2011 (IGA mod 2011), and Dermatology Life Quality Index (DLQI) were assessed. Dermatologists documented the treatment dosage and modification reasons. Of the 244 secukinumab-naïve patients, most were men (73.4%, 179/244) and weighed 60-90 kg (72.8%, 177/243). The mean (SD) age at secukinumab initiation was 38.1 (11.6) years, and the disease duration was 13.5 (7.9) years. Most patients (97.1%, 237/244) received secukinumab 300 mg. At weeks 4, 12, 16, and 24, the proportion of patients achieving PASI 75 (≥75% reduction from baseline) was 40.0%, 92.1%, 88.4%, and 88.9%, respectively; PASI 90 was 15.0%, 73.7%, 81.4%, and 68.3%, respectively; and PASI 100 was 8.7%, 40.8%, 58.1%, and 41.3%, respectively. During the same periods, BSA and IGA mod 2011 showed similar improvement trends. An increasing proportion of patients achieved DLQI of 0-1 (21.6%, 65.7%, 75.0%, and 80.3%, respectively). Treatment modification was highest at week 12. The average interval between two administrations after week 4 was 62.95 days. Secukinumab was highly effective in improving the PASI, IGA, BSA, and DLQI in Chinese patients with moderate-to-severe plaque psoriasis throughout the first 24 weeks. The treatment pattern for Chinese patients differs from that in the clinical guidelines.

Long-Term Effectiveness and Drug Survival of Secukinumab in Vietnamese Patients with Psoriasis: Results from a Retrospective ENHANCE Study

INTRODUCTION

Psoriasis (PsO), an immune-mediated inflammatory skin disorder, has substantial negative impact on patients' quality of life. Secukinumab, an approved treatment for moderate-to-severe plaque PsO, has an established long-term efficacy and safety profile. This study aims to provide real-world evidence of long-term effectiveness and retention rate of secukinumab in Vietnamese patients with PsO.

METHODS

This retrospective, observational study collected medical records of adult patients with moderate-to-severe PsO receiving secukinumab treatment from Ho Chi Minh City Hospital of Dermato-Venereology. The primary objective was to evaluate secukinumab effectiveness in PsO as measured by 75% improvement in psoriasis area and severity index (PASI 75) at month 12. Secondary objectives were PASI 90/100, absolute PASI ≤ 3 and ≤ 5, Dermatology Life Quality Index (DLQI), and retention rate over 48 months.

RESULTS

In total, 232 patients with moderate-to-severe PsO met inclusion criteria; 68.1% were male, with median age and age of onset of 39 and 27.5 years, respectively. Median time from onset of PsO to secukinumab treatment was 120 months, 95.3% were prior biologics/disease-modifying antirheumatic drugs naive and 41.4% received concomitant therapies for PsO; 82.3% had national insurance coverage. At month 12, 93.9% of patients achieved PASI 75 (primary endpoint); 80.2/56.9% achieved PASI 90/100; 91.4 and 84.8% patients achieved absolute PASI ≤ 5 and ≤ 3, respectively. The response was sustained over 48 months, with 91.9%/78.0%/52.0% of patients achieving PASI 75/90/100, 89.5% and 82.1% patients achieving absolute PASI ≤ 5 and ≤ 3, respectively. At month 12, 61.4% of patients achieved DLQI 0/1 which was sustained up to month 48 (69.2%). Secukinumab adherence rate of 84.9% at month 12 dropped to 34.2% at month 48. Patients receiving concomitant therapy and national insurance showed higher adherence rate.

CONCLUSION

Secukinumab demonstrated long-term effectiveness in real-world Vietnamese patients with moderate-to-severe PsO, with treatment adherence being higher in patients having concomitant therapies and national insurance.

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.

Gradually increasing the dosing interval of Secukinumab for moderate to severe plaque psoriasis: A single-center, uncontrolled, prospective study in 36 weeks

Secukinumab is a recombinant, fully human monoclonal anti-IL-17A antibody approved to treat moderate-to-severe psoriasis and psoriatic arthritis. Its effectiveness and safety have been confirmed, but a gradual increase in the secukinumab dosing interval has not been investigated. To assess the feasibility, efficacy, and safety of gradually increasing the secukinumab dosing interval; the interval duration was determined by changes in the Psoriasis Area and Severity Index scores. Patients with moderate-to-severe plaque psoriasis received secukinumab 300 mg subcutaneously at baseline and weeks 0, 1, 2, and 3. At week 4, the improvement from baseline PASI guided the next injection time until week 36. In total, 83 patients were recruited. PASI 75 was achieved by 80%, 96%, and 95% of patients at weeks 4, 12, and 36, respectively. PASI 90 was achieved by 54%, 95%, and 84% of patients at weeks 4, 12, and 36, respectively. PASI 100 was achieved by 28%, 89%, and 68% of patients at weeks 4, 12, and 36, respectively. The average PASI score (1.05 ± 1.83) was significantly lower at week 36 than at baseline. Most patients reached PASI 75 at week 36 in our modified study. This study may provide information for future biotherapies.

Secukinumab is effective and safe in the long-term treatment of plaque psoriasis in a daily practice setting: Multicenter study in 384 Spanish patients

The aim of the study was to assess the long-term effectiveness and safety of secukinumab in Spanish patients with moderate-to-severe psoriasis in a daily practice setting. Nationwide multicenter, observational, retrospective, non-interventional, single-cohort study including patients who initiated treatment with secukinumab in daily clinical practice conditions. Subjects were followed for a minimum of 3 months and a maximum of 24 months. Psoriasis Area Severity Index (PASI), Body Surface Area and Physician's Global Assessments were collected at baseline and months 3, 6, 12, 18 and 24 during treatment. Adverse events and reasons for secukinumab withdrawal were collected and classified for analyses. A total of 384 patients were enrolled in the study. Median PASI declined rapidly from 14.3 at baseline to 2.7 at month 3, 2.1 at month 12, and remained low (2.8) at month 24. Within the group of patients with PASI ≥10 at baseline (n = 278), 58.3%, 60.4% and 56.5% achieved a PASI90 response at months 3, 12 and 24, respectively. As for absolute PASI, 86.5%, 69.5%, 42.7% and 37% achieved PASI <5, < 3, < 1 and 0, respectively, at month 3. Secukinumab was more effective in biologic-naïve patients and in those with lower Body Mass Index. Secukinumab presented a good long-term safety profile. Secukinumab was effective and safe in a routine clinical setting, in a large cohort of patients with moderate-to-severe plaque psoriasis, in the short-, medium- and long-term (up to 24 months).

Secukinumab in Patients with Psoriasis and a Personal History of Malignancy: A Multicenter Real-Life Observational Study

Introduction

There is limited evidence to guide clinicians on the treatment of psoriasis with biologics in patients with a history of malignancy who are often excluded from clinical trials investigating biologics. The aim of this work is to report a multicenter real-life experience of secukinumab treatment in patients with psoriasis and a personal history of cancer.

Methods

This retrospective observational study included adult patients with moderate-to-severe plaque psoriasis treated with secukinumab for at least 24 weeks and a previous diagnosis of cancer at 15 Italian referral centers. The primary endpoint of the study was tumor recurrence or progression and new cancer diagnosis during treatment. Secondary outcome assessment of secukinumab effectiveness (reduction of Psoriasis Area and Severity Index [PASI] score, improvement of Dermatology Life Quality Index [DLQI], itch and pain).

Results

Forty-two patients (27 male) were included. Malignancy was diagnosed in the previous 5 years in 21 (56.8%) and in the previous 10 years in 37 (88.1%). The mean interval between cancer diagnosis and the start of secukinumab treatment was 3.5 ± 3.3 years. No tumor recurrence nor progression occurred over a mean of 56 ± 31.7 weeks of treatment. Three patients developed a new malignancy not related to the previous cancer. At week 48, PASI 90 was reached by 64.7% of patients and PASI 100 by 38.2%. Mean DLQI, itch, and pain VAS scores significantly improved during treatment.

Conclusions

Our multicenter real-life experience is the largest reported to date focusing on a specific biologic and adds evidence to the safety of secukinumab in psoriatic patients with a personal history of cancer.

Efficacy of Tildrakizumab Across Different Body Weights in Moderate-to-Severe Psoriasis Over 5 Years: Pooled Analyses from the reSURFACE Pivotal Studies

Introduction

Tildrakizumab (TIL), a monoclonal antibody that selectively targets interleukin-23p19, has been approved for the treatment of moderate-to-severe plaque psoriasis. According to the European Medicines Agency Summary of Product Characteristics, the recommended dose is 100 mg, but a 200 mg dose can be used in patients with certain characteristics, such as a high disease burden or body weight (BW) ≥ 90 kg. Fixed one-dose biological therapies tend to become less effective in patients with high BW. This post-hoc study describes the long-term efficacy of TIL across different BWs in pivotal clinical trials.

Methods

A 5-year pooled analysis of two double-blind, randomised, controlled phase III trials—reSURFACE 1 and 2—was performed. Efficacy measures were the proportions of the patients with an absolute Psoriasis Area and Severity Index (PASI) of < 3 and < 1 and a Dermatology Life Quality Index (DLQI) of 0/1. The study population included patients randomised to TIL 100 mg or TIL 200 mg who received ≥ 1 TIL dose up to week 12 (part 1 of the trial) or up to week 28 (part 2) and patients who were responders (≥ 75% improvement in PASI) to TIL 100 or TIL 200 mg at week 28 and who were maintained on the same dose up to week 244. Efficacy was evaluated by analysing BW subgroups at weeks 28, 52 and 244. Missing data were analysed using multiple imputation. Safety was assessed in the all-patients-as-treated population.

Results

The proportions of TIL-treated patients with PASI < 3 and < 1 (up to week 244) and DLQI 0/1 (up to week 52) were similar for patients with BW < 90 or ≥ 90 kg, regardless of dose. Patients ≥ 120 kg had greater efficacy outcomes at the 200 mg dose. Safety outcomes were similar regardless of treatment dose and weight (< 120/≥ 120 kg).

Conclusion

In patients with BW ≥ 120 kg, TIL 200 mg is more efficacious than TIL 100 mg, with similar favourable safety profiles obtained regardless of dose and BW group.

On and off-label uses of interleukin-17 inhibitors for patients with plaque-type psoriasis in Thailand: a real-world study

BACKGROUND

Off-label uses of biologics in the treatment of psoriasis are usually implemented in limited-resource settings and studies regarding their response profiles are limited.

METHOD

This was a retrospective study performed in moderate-to-severe plaque-type psoriasis patients who had been treated with either secukinumab, ixekizumab or brodalumab at a university hospital in Thailand between 1 January 2017 and 1 April 2021.

RESULTS

A total of 142 patients were included in the data analysis consisting of three groups of 48 patients, 86 patients, and 8 patients treated by secukinumab, ixekizumab, and brodalumab, respectively. Patients were then classified into five groups according to the dosing pattern they received; on-label, off-label with induction, off-label with specific pattern, off-label with irregular dosing interval <8 weeks and >8 weeks. Considering both secukinumab and ixekizumab, the adjusted hazard ratios (95%CI) for complete skin clearance of the four off-label regimens were 2.2(0.9-5.2), 1.9 (0.9-3.9), 1.0 (0.4-2.2), and 1.6 (0.7-3.6), compared to on-label regimen, respectively. In each biologic drug, almost all off-label dosing regimens demonstrated higher adjusted hazard ratios compared to on-label regimen.

CONCLUSION

Off-label, patient-oriented regimens could be a promising choice of IL-17 inhibitors for administration in special settings. Off-label regimens are not inferior in terms of skin clearance to an on-label regimen in the efficacy of psoriasis treatment of secukinumab and ixekizumab but do cause more flares. The decision to use off-label regimens must account for the benefits and associated risks.

Utilization Trends and Impact of Secukinumab Treatment on Clinical Outcomes in Biologic-Naive Patients with Psoriasis in a US Real-World Setting

INTRODUCTION

Real-world evidence has demonstrated the effectiveness of secukinumab in the treatment of psoriasis; however, limited data are available on patient profiles of US secukinumab initiators over time and clinical outcomes in biologic-naive patients. This study describes clinical characteristics of secukinumab initiators by year, and the clinical outcomes in patients after 6- and/or 12-month follow-up visits, stratified by prior biologic use.

METHODS

This observational study included patients enrolled in the CorEvitas (formerly Corrona) Psoriasis Registry. Analyses were conducted in two patient cohorts: (1) all secukinumab initiators, stratified by year, and (2) those who initiated and maintained secukinumab through a 6- and/or 12-month follow-up visit. For all secukinumab initiators, patient characteristics at initiation were described per calendar year; in initiators with follow-up visits, mean (SD) differences in percentage affected body surface area (BSA), five-point Investigator's Global Assessment (IGA), and Psoriasis Area and Severity Index (PASI) scores between baseline and follow-up visits were calculated. Analyses were conducted separately for biologic-naive and biologic-experienced patients.

RESULTS

Between 2015 and 2020, the proportion of secukinumab initiators in the registry who were biologic-naive increased each year from 12.5% to 49.7%. Overall, 1518 patients initiated secukinumab at or after enrollment; 980 (64.6%) were biologic experienced, and 538 (35.4%) were biologic naive. At 6 months, biologic-experienced and biologic-naive patients reported mean (SD) decreases in BSA (-9.3 [14.5] versus -11.7 [16.6]), IGA (-1.4 [1.3] versus -1.7 [1.4]), and PASI (-5.2 [6.6] versus -6.7 [7.8]). The proportion of patients with an IGA score of clear/almost clear (0/1) increased over fivefold, irrespective of biologic experience. At 12 months, similar improvements were seen.

CONCLUSIONS

The proportion of biologic-naive secukinumab initiators increased over time. Biologic-naive patients demonstrated similar improvements in clinical outcomes compared with biologic-experienced patients, suggesting that secukinumab may be considered as a first-line therapy for psoriasis.

Successful use of secukinumab in two melanoma patients with immune checkpoint inhibitor-induced inflammatory arthropathy

Immune-related adverse events (irAEs) are a major concern when treating cancer patients with immune checkpoint inhibitor (ICI) therapy. Selecting the most appropriate management of irAEs remains an ongoing challenge because prolonged use of glucocorticoids come with their own side effects and may counteract the antineoplastic effects from immunotherapy. In this case report, we present two patients with metastatic melanoma who developed symptoms of inflammatory arthritis attributed to ICI therapy. We found that treatment with secukinumab, an anti-IL-17A inhibitor, effectively managed their symptoms and did not lead to tumor progression. Our study suggests that secukinumab can be a safe and effective treatment option for ICI-induced inflammatory arthropathy.

The dark side of the moon: the immune-mediated adverse events of IL-17A/IL-17R inhibition

As aberrant IL-17 signaling plays a critical role in the pathogenesis of psoriasis, biologic agents targeting this pathway have become an important weapon against this disease. Some biologic agents such as IL-17 inhibitors (secukinumab and ixekizumab) and the IL-17 receptor (IL17R) inhibitor (brodalumab) are relatively safe, tolerable and efficacious drugs. Nevertheless, side effects of IL-17 pathway inhibition occur. This review focuses on the dermatological manifestations linked to these treatments. Paradoxical psoriasis and atopic-like eczema may be the most common cutaneous adverse events, while manifestations such as neutrophilic dermatoses, hypersensitivity reactions, lichenoid eruptions, vasculitides, bullous diseases, lupus-like reactions, pigmentation disorders, adnexal diseases and granulomatous dermatoses have been described less frequently.

Secukinumab demonstrates efficacy, safety and tolerability upon administration by 2 mL autoinjector in adult patients with plaque psoriasis: 52-week results from MATURE, a randomized, placebo-controlled trial

Convenient administration is an important factor for treatment adherence in patients with psoriasis. MATURE study reports the efficacy, safety, tolerability, and pharmacokinetics of secukinumab 300 mg 2 mL autoinjector (AI) from MATURE trial (NCT03589885). Eligible patients were randomized to secukinumab 300 mg 2 mL AI or 2x 1 mL pre-filled syringe (PFS) or placebo. The co-primary endpoints were Psoriasis Area and Severity Index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 response rates at Week 12 versus placebo. Other endpoints included PASI90/100 response, Dermatology Life Quality Index (DLQI) 0/1, pharmacokinetics, 2 mL AI usability rated using Self-Injection Assessment Questionnaire (SIAQ), and safety. The study met both co-primary and secondary endpoints (p < 0.0001). Secukinumab 300 mg 2 mL AI and 2x 1 mL PFS treatments led to superior PASI75/90/100 (2 mL AI: 95.1%/75.6%/43.9%; 2x 1 mL PFS: 83.2%/62.6%/37.5% and placebo: 10%/5.0%/0.0%, respectively), IGA, and DLQI 0/1 responses compared with placebo, and efficacy was sustained through 52 weeks. SIAQ results showed high usability of self-injection with 2 mL AI device. No new safety signals were observed. Study design may bias the interpretation of safety profile after Week 12, due to different exposure of secukinumab versus placebo. Secukinumab 300 mg administered with the 2 mL AI demonstrated superior efficacy over placebo, good tolerability and convenient administration. This article is protected by copyright.

Use of Biological Treatments in Elderly Patients with Skin Psoriasis in the Real World

Biological drugs have prompted a revolution in the treatment of patients with psoriasis because of their favourable efficacy/risk profile. The aims of our study are to determine whether there is any difference in the pattern of use of biological treatments for older (65+ years) and younger patients diagnosed with plaque psoriasis by the Dermatology Service of the Hospital Universitario de Asturias (HUCA), to understand the survival of these drugs, and to identify the factors that predict the discontinuation of treatments. We report a retrospective observational hospital-based study of 300 patients registered at HUCA’s Dermatology Service who were receiving one of the following biological treatments for psoriasis on 30 November 2020: adalimumab, ustekinumab, secukinumab, or ixekizumab. The age groups were compared using Student’s t-test for quantitative variables and the chi-squared test for qualitative variables. We used the Kaplan–Meier estimator to estimate the survival function and the log-rank test to measure differences. No statistically significant differences in the frequency of use were noted between the younger and older groups, for any of the drugs studied. Survival on a drug regime, globally and individually, was similar in the two age groups. Factors predicting lower overall survival were being female, obesity, and having undergone previous biological treatment. The first three factors were influential in the under-65-year-old group, while arthritis was a significant factor for the older group.

Real-world evidence of biologic treatments in moderate-severe psoriasis in Italy: Results of the CANOVA (EffeCtiveness of biologic treAtmeNts for plaque psOriasis in Italy: An obserVAtional longitudinal study of real-life clinical practice) study

EffeCtiveness of biologic treAtmeNts for plaque psOriasis in Italy: An obserVAtional (CANOVA) study was aimed at providing real-world evidence of the effectiveness of biologics in Italian patients with moderate-severe psoriasis. It was an observational, retro-prospective cohort study conducted in 17 Italian dermatology clinics. Adult patients with moderate-severe plaque psoriasis, who started a biologic treatment between 24 weeks and 24 months before enrolment, were included. With a follow-up visit at 6 months after enrolment, each patient had at least 12 months of observation. The primary objective was to describe the clinical response rates (PASI 75) after 16/24/52 weeks from biologic treatment start. Secondary outcomes were sustained response, quality of life, and treatment satisfaction. Of the 669 eligible patients (64% males), 52% were naïve to biologics, though a mean duration of psoriasis since first diagnosis of 18.6 years (SD 13.2). The most frequently prescribed biologics were secukinumab (41%), ustekinumab (25%), TNF-inhibitors (22%) and ixekizumab (12%). PASI 75 was achieved by 86% of patients (95% CI: 82%-89%) at 16 weeks, 90% (87%-93%) at 24 weeks, and 91% (89%-94%) at 52 weeks. Patients achieving PASI 90 and PASI 100 at 52 weeks were 75% (71%-79%) and 53% (49%-57%), respectively. Sustained PASI 75 response after 1 year from treatment start was achieved by 78% (74%-82%) of patients. Mean DLQI total score was 2.3 (SD 3.9) at enrollment and decreased at the final visit to 1.8 (3.6). A high level of treatment satisfaction was expressed by patients over the study period. This large real-world study confirms in the clinical practice the good effectiveness and acceptability of biologics in psoriasis patients.

Costo per responder di risankizumab e secukinumab nel trattamento della psoriasi a placche da moderata a grave in Italia

Purpose:

The objective of this analysis was to compare the cost per responder between risankizumab and secukinumab among patients with moderate-to-severe plaque psoriasis in Italy.

Methods:

The clinical efficacy was assessed based on IMMerge study of published efficacy data as measured by Psoriasis Area and Severity Index response (PASI 90 and PASI 100) for risankizumab and secukinumab. The treatment cost was based on the number of administrations dispensed in the first (induction plus maintenance period) and the second (maintenance period only) year of treatment and the ex-factory price of each treatment. The cost per responder was adopted as a cost-effectiveness indicator.

Results:

Independently of the PASI response (PASI 90 and PASI 100) used and the year of treatment considered, the cost per responder was consistently lower for risankizumab compared to secukinumab in all clinical measures. For example, considering the first-year costs and PASI 100, the cost per responder for risankizumab was € 24,506.83 compared to € 38,000.00 for secukinumab. The differences in the cost per responder between risankizumab and secukinumab increased when higher PASI response levels were considered.

Conclusion:

This economic evaluation suggested that the cost per responder is consistently lower for risankizumab compared to secukinumab from the perspective of the Italian National Health Service in the treatment of moderate-to-severe plaque psoriasis.

Effectiveness of brodalumab after previous treatment failure of interleukin-17A inhibitors in patients with psoriasis

Studies on switch between interleukin (IL)-17 inhibitors are scarce. We assessed the effectiveness of brodalumab in patients with previous treatment failure of IL-17A inhibitor(s). Patients with psoriasis and previous treatment failure of an IL-17A inhibitor were treated with brodalumab at standard dose. Effectiveness was assessed after 12, 26, and 52 weeks of treatment. The primary outcome was the proportion of patients that had achieved an absolute psoriasis area and severity index (PASI) ≤2 and/or a relative reduction of PASI of 75% (PASI75) at week 12. Plasma cytokine levels were measured at baseline and after 12 weeks of treatment. In total, 20 patients were included, seven (35%) were female, the median age was 50 years, and the median baseline PASI was 13.5. Analyzing the data using nonresponder imputation, 14 (70%) patients had achieved either PASI75 and/or PASI ≤2, 8 (40%) had achieved PASI90, and three (15%) had achieved PASI100 at week 12. In total, nine patients (45%) completed the 52-weeks trial and seven patients (35%) still had PASI75 throughout 52 weeks. Seventeen out of 20 patients experienced any adverse events (AEs) during 52 weeks with no serious AEs or deaths. Patients responding to treatment had lower levels of tumor necrosis factor (TNF)-α and IL-6 at baseline compared with those who did not respond to treatment (TNF-α, p = 0.041, IL-6, p = 0.0054). In conclusion, treatment with brodalumab despite previous treatment failure with an IL-17A inhibitor can be effective and well-tolerated.

Gastroenterological safety of IL-17 inhibitors: a systematic literature review

INTRODUCTION

Interleukin 17 is a proinflammatory cytokine considered to play a significant role in the immunopathogenesis of many chronic immune-mediated disorders. Interleukin 17 inhibitors provide an excellent treatment option for patients with psoriasis, psoriatic arthritis, or ankylosing spondylitis. However, Interleukin 17 inhibitors have been suspected of worsening or triggering new-onset inflammatory bowel disease.

AREAS COVERED

A literature search was conducted until March 2021 to investigate reporting prevalence, and characteristics of all gastroenterological adverse events in patients treated with Interleukin 17 inhibitors. One hundred and six clinical randomized trials were included, involving 40,053 patients. Inflammatory bowel disease cases were reported in 0.4% of patients exposed to Interleukin 17 inhibitors. The most frequent other gastrointestinal adverse events were diarrhea (2.5%), nausea or vomiting (0.7%), and gastroenteritis (0.2%). Sixty-one uncontrolled or retrospective studies were included, involving 16,791 patients. Sixty (0.36%) inflammatory bowel disease cases were reported, 0.6% of patients reported other gastrointestinal adverse events.

EXPERT OPINION

Interleukin 17 inhibitors are safe and effective in the treatment of psoriasis, psoriatic arthritis, and ankylosing spondylitis. Low incidence rate of developing new-onset inflammatory bowel disease or exacerbating preexisting inflammatory bowel disease with anti-IL-17 agents has been reported. Clinicians should be aware of the possibility of these concerns when considering this therapy.

Secukinumab for the treatment of psoriasis, psoriatic arthritis, and axial spondyloarthritis: Physical and pharmacological properties underlie the observed clinical efficacy and safety

Psoriasis, psoriatic arthritis, and axial spondyloarthritis are systemic inflammatory diseases, each commonly manifesting as a spectrum of symptoms, complications, and comorbidities that arise differently in individual patients. Drugs targeting inflammatory cytokines common to the pathogenesis of each of these conditions have been developed, although their specific actions in the different tissues involved are variable. For a drug to be effective, it must be efficiently delivered to and locally bioactive in disease-relevant tissues. Detailed clinical data shed light on the therapeutic effects of individual biologics on specific domains or clinical manifestations of disease and assist in guiding treatment decisions. Pharmacologic, molecular, and functional properties of drugs strongly impact their observed safety and efficacy, and an understanding of these properties provides complementary insight. Secukinumab, a fully human monoclonal IgG1/κ antibody selectively targeting interleukin (IL)-17A, has been in clinical use for >6 years in the treatment of moderate to severe psoriasis, psoriatic arthritis, and both radiographic (also known as ankylosing spondylitis) and nonradiographic axial spondyloarthritis. In this review, we discuss pharmacokinetic and pharmacodynamic data for secukinumab to introduce clinicians to the pharmacological properties of this widely used drug. Understanding how these properties affect the observed clinical efficacy, safety, and tolerability of this drug in the treatment of IL-17A-mediated systemic inflammatory diseases is important for all physicians treating these conditions.

The risk of malignancy in patients with secukinumab-treated psoriasis, psoriatic arthritis and ankylosing spondylitis: analysis of clinical trial and postmarketing surveillance data with up to five years of follow-up

BACKGROUND

Data on the use of biologic therapy and malignancy risk are inconsistent due to limited long-term robust studies.

OBJECTIVES

To assess the malignancy risk in patients with secukinumab-treated psoriasis, psoriatic arthritis (PsA) and ankylosing spondylitis (AS).

METHODS

This integrated safety analysis from both the secukinumab clinical trial programme and postmarketing safety surveillance data included any patient receiving at least one approved dose of secukinumab with a maximum of 5 years of follow-up. Safety analyses evaluated the rate of malignancy using exposure-adjusted incidence rates [EAIR; incidence rates per 100 patient treatment-years (PTY)]. Standardized incidence ratios (SIRs) were reported using the Surveillance, Epidemiology, and End Results Program (SEER) database as a reference population. Crude incidence of malignancy was also reported using postmarketing surveillance data.

RESULTS

Safety data from 49 clinical trials with secukinumab-treated patients were included: 10 685 patients with psoriasis, 2523 with PsA and 1311 with AS. Across indications over a 5-year period, the EAIR of malignancy was 0·85 per 100 PTY [95% confidence interval (CI) 0·74-0·98] in secukinumab-treated patients, corresponding to 204 patients per 23 908 PTY. Overall, the observed vs. expected number of malignancies from secukinumab clinical trial data were comparable, as indicated by an SIR of 0·99 (95% CI 0·82-1·19) across indications. The estimated crude cumulative incidence reporting rate per 100 PTY for malignancy was 0·27 in the postmarketing surveillance data across indications with a cumulative exposure of 285 811 PTY.

CONCLUSIONS

In this large safety analysis, the risk of malignancy was low for up to 5 years of secukinumab treatment. These data support the long-term use of secukinumab in these indications.

Therapeutics targeting the IL-23 and IL-17 pathway in psoriasis

Psoriasis is a chronic inflammatory disease characterised by sharply demarcated erythematous and scaly skin lesions accompanied by systemic manifestations. Classified by WHO as one of the most serious non-infectious diseases, psoriasis affects 2-3% of the global population. Mechanistically, psoriatic lesions result from hyperproliferation and disturbed differentiation of epidermal keratinocytes that are provoked by immune mediators of the IL-23 and IL-17 pathway. Translational immunology has had impressive success in understanding and controlling psoriasis. Psoriasis is the first disease to have been successfully treated with therapeutics that directly block the action of the cytokines of this pathway; in fact, therapeutics that specifically target IL-23, IL-17, and IL-17RA are approved for clinical use and show excellent efficacy. Furthermore, inhibitors of IL-23 and IL-17 intracellular signalling, such as TYK2 or RORγt, are in clinical development. Although therapies that target the IL-23 and IL-17 pathway also improve psoriatic arthritis symptoms, their effects on long-term disease modification and psoriasis-associated comorbidities still need to be explored.

New generation biologics for the treatment of psoriasis and psoriatic arthritis. State of the art and considerations about the risk of infection

Psoriasis is a chronic immune-mediated disease characterized by inflammation of skin (psoriasis) or joints (psoriatic arthritis) or both, resulting from a dysregulation in particular of the T helper (Th)17 functions. There is no available cure for psoriasis, and a life-long treatment is needed to control signs and symptoms. Research interest is high around the newest biological drugs approved for the treatment of moderate to severe psoriasis and psoriatic arthritis, and especially drugs blocking the IL-23/IL-17 axis. Our aim is to review the new biological drugs for the treatment of psoriasis and their adverse effects, focusing on the risk of infections.

Effectiveness of anti-interleukin 23 biologic drugs in psoriasis patients who failed anti-interleukin 17 regimens. A real-life experience

Among the most recent biologic drugs available for psoriasis therapy, those targeting interleukin-17 (secukinumab and ixekizumab) or its receptor (brodalumab) have been shown to be quickly effective. However, in those patients who failed one or more of the above-cited drugs, real-life data on the effectiveness of switching to one anti-interleukin-23 biologic (guselkumab, risankizumab, or tildrakizumab) are very scarce. Here, we report our experience in treating 12 multi-failure psoriatic patients, prospectively followed-up over 6 months, who showed a significant improvement in their psoriasis after switching from an anti-interleukn-17 to an anti-interleukin-23 drug.

Erythrodermic psoriasis successfully and rapidly treated with brodalumab: Report of two cases

Erythrodermic psoriasis (EP) is a rare form of the disease clinically characterized by a generalized erythema covering ≥90% of the body surface area (BSA). The management of EP is challenging: no standardized guidelines exist with literature suggesting cyclosporine or infliximab as first-line therapy. However, a recent systematic review showed a positive response in EP patients treated with biologic agents. The most common biologic used for EP up until now has been ustekinumab, whereas infliximab might represent a first-line option in case of complicated EP (acute, severe, or unstable). Up until now, no case of brodalumab (a monoclonal antibody blocking IL-17 receptor) treatment for EP in real-life has ever been described. Here, we report the first two cases of efficacy and safety of brodalumab in real-life cases of EP.

Candida infections in patients with psoriasis and psoriatic arthritis treated with interleukin-17 inhibitors and their practical management

INTRODUCTION

Interleukin 17A (IL-17A) is a pro-inflammatory cytokine produced by helper T cells (Th17) and other cells of the immune system and exerts pleiotropic effects on multiple cell lines. The role of IL-17 in the pathogenesis of numerous inflammatory disorders is well-documented. IL-17 activates signaling through the IL-17 receptor, which induces other proinflammatory cytokines, antimicrobial peptides, and neutrophil chemokines that are important for antifungal activity.

EVIDENCE ACQUISITION

Healthy levels of IL-17 can protect the host against extracellular bacterial and fungal infections in mucous membranes and epithelia. IL-17 deficiency reduces control of certain infections, while excessive IL-17 can produce unwanted inflammatory effects.

EVIDENCE SYNTHESIS

Although the efficacy of the therapeutic blockade of this cytokine has been proven in several autoimmune diseases such as psoriasis and psoriatic arthritis, this strategy could also exacerbate fungal infections in such patients. Therefore, a better understanding of IL-17-mediated immunity to Candida is necessary for the development of autoimmune therapeutics that maintain antifungal immunity.

CONCLUSIONS

In this review, we include a study of the new anti-IL-17 biological agents (secukinumab, ixekizumab, and bromalizumab) used for moderate-to-severe psoriasis and psoriatic arthritis treatment in clinical practice, as well as pivotal trials with bimekizumab. We study the relationship of these biological agents and the appearance of candidiasis in its various clinical forms.

Changes in metabolic parameters in psoriatic patients treated with secukinumab

Background:

Psoriasis is associated with cardiovascular disease and metabolic syndrome but the effects of interleukin (IL)-17A inhibitor treatment on metabolic parameters are unknown. This study aimed to determine the effects of secukinumab on metabolic parameters based on the disease activity and treatment response in patients with psoriasis.

Methods:

In this retrospective study, we included 99 patients with moderate to severe psoriasis, who received IL-17 inhibitor (secukinumab) treatment for 24 weeks between January 2016 and February 2020. The disease activity [Psoriasis Area and Severity Index (PASI)] and metabolic parameters at baseline and after 12 or 24 weeks of treatment were collected.

Results:

The PASI improved with a significant reduction of high-sensitivity C-reactive protein (hs-CRP) at weeks 12 and 24 respectively. However, body weight and body mass index were significantly increased at week 12 and 24 of treatment. Triglycerides level and atherogenic index of plasma were significantly higher in week 24 in PASI-90 non-responders. The baseline hs-CRP level and PASI-90 non-response correlated with elevated triglyceride levels.

Conclusion:

Our results suggest that obesity and hypertriglyceridemia still existed in patients despite the improved disease activity after secukinumab treatment. Higher baseline hs-CRP level and PASI-90 non-response were predictors for elevated triglyceride levels after treatment. Therefore, patient education, regular screening of the lipid profile, and weight control are recommended during the treatment of secukinumab.

Efficacy of a second interleukin 17 inhibitor in patients with psoriasis: A systematic review and meta-analysis

BACKGROUND

Multiple biologics for psoriasis exist, and interleukin (IL) 17 inhibitors are among those with the best efficacy. However, switching treatment is often required at some point, and intraclass switch of IL-17 inhibitors is not well investigated.

OBJECTIVES

To determine the efficacy of a second IL-17 inhibitor in patients with psoriasis.

METHODS

Two authors independently searched the databases PubMed and EMBASE for studies reporting on efficacy of IL-17 inhibitors in patients with psoriasis previously exposed to another IL-17 inhibitor. The study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

In total, 14 publications comprising 655 patients were included. The proportion of patients achieving a reduction of 75%, 90%, and 100% in Psoriasis Area Severity Index were, respectively, 74.6 (95% confidence interval [CI], 63.9-84.0), 69.4% (95% CI, 53.2-83.4), and 46.4 (95% CI, 30.5-62.7) after short-term treatment (weeks 9, 12, and 16 combined).

LIMITATIONS

Most studies included were on ixekizumab and were retrospective chart reviews with no information on the response to the previous IL-17 inhibitor.

CONCLUSION

Previous treatment with an IL-17 inhibitor does not appear to affect the efficacy of another IL-17 inhibitor in the treatment of psoriasis. However, further prospective studies are needed.

Treatment of Psoriasis with Secukinumab in Challenging Patient Scenarios: A Review of the Available Evidence

Psoriasis (PsO) is a common, systemic, chronic, inflammatory disease characterized by key clinical symptoms, including itching, pain, and scaling. PsO is associated with a high prevalence of comorbidities, including other autoimmune diseases and malignancies. Furthermore, special populations, such as pregnant, pediatric, and elderly patients, and those with erythrodermic PsO, are challenging to treat and require tightly monitored disease and treatment management. Because certain populations have demographic or clinical characteristics that can affect the presentation of PsO and complicate treatment responses, these patient populations are largely excluded from clinical trials; therefore, most clinical evidence for the treatment of these patients is derived from case reports and series. Secukinumab, a fully human monoclonal interleukin-17A antibody, has been shown in several clinical trials to be effective and safe for the treatment of PsO; however, these studies offer only limited data on the use of secukinumab in patients with chronic illnesses or in special populations. This review explores the use of secukinumab for PsO in special populations, including pregnant women, children, elderly people, patients with erythrodermic PsO, and those with chronic illnesses, including latent tuberculosis, hepatitis B and C, HIV, multiple sclerosis, and malignancies.

Real-world evidence of secukinumab in psoriasis treatment - a meta-analysis of 43 studies

Real-world evidence (RWE) meta-analyses provide valuable insights from patients in routine clinical practice. Secukinumab, the first fully human monoclonal antibody that neutralizes IL-17A, has shown long-lasting effectiveness and safety in plaque psoriasis (PsO). Since its licence approval in 2015, many RWE studies have been published. The objective of this study was to review all available literature on RWE studies with secukinumab and the secukinumab arm of comparator studies in patients with moderate-to-severe PsO to evaluate its effectiveness, drug survival and safety. https://www.embase.com and https://clinicaltrials.gov databases were searched using prespecified inclusion criteria between 1 January 2015 and 31 May 2019. Using a meta-package and R statistical software to analyse data, key outcomes were measured at 3, 6 and 12 months. PASI and DLQI score data were recorded for patients who remained on secukinumab treatment. Overall, 43 studies were included. Drug survival was 90% at 3 and 6 months, and 80% at 12 months. At 12 months, 8% of patients had discontinued treatment due to lack of effectiveness. At 3, 6 and 12 months, Psoriasis Area and Severity Index (PASI) 90 scores were as follows: 50%, 53% and 60%, and PASI 100 scores were 36%, 46% and 51%, respectively. At 3, 6 and 12 months, 57%, 55% and 65% of patients achieved a Dermatology Life Quality Index (DLQI) score of 0 or 1, respectively. Adverse events were consistent with rates observed in clinical trials with no new safety signals. This meta-analysis strengthens existing evidence on the clinical effectiveness of secukinumab in patients with moderate-to-severe PsO, demonstrating high drug survival rates, high levels of patient-reported outcomes, and good tolerance.
