Efficacy, safety, and drug survival of patients with psoriasis treated with IL-17 inhibitors – brodalumab, ixekizumab, and secukinumab: real-world data from the Czech Republic BIOREP registry

The role of bDMARDs in the prevention and treatment of inflammatory-related comorbidities in Psoriatic Arthritis

INTRODUCTION

Psoriatic arthritis (PsA) is an immune-inflammatory disease that affects both joints and entheses, and with diverse extra-articular manifestations (psoriasis, inflammatory bowel disease (IBD), and uveitis). A wide range of comorbid conditions, including cardiovascular diseases, obesity, metabolic syndrome (MetS), nonalcoholic fatty liver disease (NAFLD), mental health disorders (depression/anxiety), and osteoporosis are highly prevalent in course of PsA.Biological DMARDs (bDMARD), including TNF-inhibitors (TNFi), Interleukin (IL-17i) and IL-23i represent the cornerstone of the management of active disease. The use of these therapies obviously requires considering comorbidities presence, safety aspects and contraindications.

AREAS COVERED

The aim of this review is to describe the inflammatory mechanisms behind PsA comorbidities, and the role of bDMARDs in the prevention and treatment of these conditions in course of PsA.

EXPERT OPINION

Tailoring therapeutic strategies to the individual characteristics of each PsA patient can be an effective approach to manage comorbidities, maximizing the efficacy of bDMARDs, and reducing the incidence of AEs. Identifying targets within disease pathways can guide research into therapeutics that address both PsA and comorbidities simultaneously, but more studies are advocated for clarifying the potential prevention and management of bDMARDs used for PsA.

Drug Survival of IL-17 and IL-23 Inhibitors for Psoriasis: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVE

The most recently approved biologics for moderate-to-severe psoriasis are the interleukin (IL)-17 and IL-23 inhibitors. Drug survival is a frequently used outcome to assess drug performance in practice. An overview of the available drug survival studies regarding IL-17 and IL-23 inhibitors is lacking. Therefore, our objective was to assess the drug survival of IL-17 and IL-23 inhibitors for psoriasis.

METHODS

A search of PubMed, Embase, Cochrane Library and Web of Science was conducted (last search 27 December, 2023). Inclusion criteria were (1) cohort study; (2) patients aged ≥ 18 years with plaque psoriasis; and (3) evaluation of drug survival of at least one of the IL-17 and IL-23 inhibitors. Exclusion criteria were: primary focus on patients with psoriatic arthritis, fewer than ten study subjects and another language than English. The Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline was followed. Survival probabilities at monthly intervals were extracted from Kaplan-Meier curves using a semi-automated tool. Data were pooled using a non-parametric random-effects model to retrieve distribution-free summary survival curves. Summary drug survival curves were constructed per biologic for different discontinuation reasons: overall, ineffectiveness and adverse events, and split for the effect modifier biologic naivety. Results were analysed separately for registry/electronic health record data and for pharmacy/claims data.

RESULTS

A total of 69 studies aggregating drug survival outcomes of 48,704 patients on secukinumab, ixekizumab, brodalumab, guselkumab, risankizumab, and tildrakizumab were included. Summary drug survival estimates of registry/electronic health record studies for overall, ineffectiveness and adverse event related drug survival were high (all point estimates ≥ 0.8 at year 1) for included biologics, with highest estimates for guselkumab and risankizumab. All estimates for drug survival were higher in biologic naive than in experienced patients. Estimates of pharmacy/claims databases were substantially lower than estimates from the primary analyses based on registry/electronic health record data.

CONCLUSIONS

This meta-analysis showed that the investigated IL-17 and IL-23 inhibitors had high drug survival rates, with highest rates for guselkumab and risankizumab drug survival. We showed that effect modifiers such as biologic naivety, and the source of data used (registry/electronic health record data vs pharmacy/claims databases) is relevant when interpreting drug survival studies.

Management of moderate to severe psoriasis with brodalumab-Real-world evidence from the LIBERO study

BACKGROUND

Brodalumab, a fully human monoclonal immunoglobulin IgG2 antibody that binds the human interleukin 17 receptor subunit A, is available for the treatment of moderate-to-severe plaque psoriasis in Europe since September 2017, but so far there are only a few studies on its use in real-world conditions.

OBJECTIVES

To assess the management of moderate-to-severe psoriasis with brodalumab 210 mg in daily practice after 12 and 52 weeks (W). In addition, patient profiles and treatment pathways are described.

METHODS

LIBERO is a prospective, multicenter, non-interventional study including adult patients with plaque psoriasis treated with brodalumab 210 mg.

RESULTS

In total, 638 patients (65% male, mean age: 49.3 ± 14.4 years) from 148 sites in Germany were enrolled. The majority suffered from severe (51.1%) or very severe (13.1%) psoriasis according to physician global assessment (PGA0-5). When starting with brodalumab, 58.5% were biologic naïve and 41.5% were previously treated with another biologic, mainly adalimumab (18.5%) and secukinumab (17.9%). About 74.0% of patients met the primary endpoint of an absolute PASI ≤3 at ~W12 (n = 618, LOCF). The mean PASI was reduced significantly as of ~W2 from 17.2 (±11.7) to 9.7 (±8.8) and improved further to 3.3 (±6.3) at ~W12 (p < 0.001). At ~W52 85.5% of patients reached a PGA0/1-response (primary endpoint) and 54.1% patients were assessed as completely clear (PGA0) (both n = 399, as observed). Effectiveness of brodalumab was confirmed in relevant subgroup analysis by previous treatment regimen. Most frequently reported adverse events were nasopharyngitis (4.6%), psoriasis (4.6%) and arthralgia (4.1%), new safety signals were not detected.

CONCLUSION

This representative, non-interventional study confirms the short- and long-term effectiveness and safety profile of brodalumab in the management of psoriasis in daily practice as well as in relevant treatment pathways.

Long-Term Effectiveness of Brodalumab for the Treatment of Moderate-To-Severe Psoriasis: A Real-Life Multicenter Study of Up to 3 Years in a Real-Life Italian Cohort

INTRODUCTION

Data about the long-term effectiveness of brodalumab could be valuable in assessing patient adherence to treatment and improving psoriasis management.

OBJECTIVE

The aim of our study was to evaluate the drug survival of brodalumab and identify any predictive factors for discontinuation.

METHODS

A multicenter retrospective study was conducted in patients with moderate-to-severe psoriasis who were treated for up to 3 years. We extracted data from patient files, related to the characteristics of the patients and the disease. Drug survival analysis was descriptively analyzed using Kaplan-Meier survival curves. Univariable and multivariable analyses were performed to assess baseline patient characteristics that predicted clinical response.

RESULTS

The study included 90 patients. Among them, 28 (31.1%) suspended brodalumab through the observation period. At weeks 52, 104 and 156 the median PASI score were 0.0 [0.0 - 0.8], 0.0 [0.0 - 1.0] and 0.0 [0.0 - 0.0], respectively. The estimated cumulative survival rates at weeks 52 and 104 were 86.32% and 78.09%, respectively. In the multivariable survival analysis, predictor factors for overall discontinuation included body mass index (BMI) (OR 1.10, 95% CI 1.03 - 1.18), baseline PASI (OR 1.06, 95% CI 1.02 - 1.10), and psoriatic arthritis (OR 5.05, 95% CI 0.89 - 13.50).

CONCLUSIONS

Brodalumab has shown long-term effectiveness for up to 3 years. Considering baseline disease severity and patient characteristics could aid in optimizing the long-term management of psoriasis.

Drug survival, effectiveness and safety of ixekizumab for moderate-to-severe psoriasis up to 5 years

INTRODUCTION

Ixekizumab proved to be effective and safe for psoriasis treatment in several randomized clinical trials and real-life studies. Nevertheless, long-term real-world experiences are still lacking, with little data up to 4 years of treatment.

OBJECTIVES

To analyse survival, effectiveness and safety of ixekizumab in a real-life cohort of patients affected by moderate-to-severe psoriasis or psoriatic arthritis up to 260 weeks (5 years).

METHODS

We included all patients treated with ixekizumab from December 2017 to March 2021. Drug survival (DS) was analysed in patients at risk for up to 5 years. Cox analysis was adopted to evaluate possible predictive factors of discontinuation. Psoriasis Area Severity Index (meanPASI and PASI100, 90, and ≤3) was used as outcomes of effectiveness on observed patients at 16, 52, 104, 156, 208 and 260 weeks. Logistic regression was performed to identify possible predictive factors of response.

RESULTS

DS was 65.5% at 260 weeks, with being a super-responder patient (achievement of PASI100 at 16 weeks and maintained at 28 weeks) correlated with less risk of discontinuation. PASI100, 90 and ≤3 was achieved by 54.1%, 60.5% and 73% of observed patients, respectively, at 16 weeks, and by 59.1%, 81.8% and 95.5%, respectively, at 260 weeks. High mean BMI was the only factor strongly associated with less achievement of the outcomes at the earlier time points: PASI100 at 16 weeks (OR 0.93, CI 0.87-0.98, p = 0.014) and at 104 weeks (OR 0.91, CI 0.84-0.98, p = 0.019), PASI90 achievement at 16 weeks (OR 0.94, CI 0.88-0.99, p = 0.028) and 104 weeks (OR 0.91, CI 0.83-0.99, p = 0.027), and PASI ≤3 (OR 0.86, CI 0.76-0.97, p = 0.018) at 104 weeks. No severe adverse events were observed.

CONCLUSIONS

Ixekizumab showed high effectiveness and safety for up to 5 years, with survival of 2/3 of treated patients. Rapid response to treatment is predictive of long-term response.

Drug survival and clinical effectiveness of secukinumab, ixekizumab, brodalumab, guselkumab, risankizumab, tildrakizumab for psoriasis treatment

BACKGROUND

Biologics targeting IL-23 and IL-17 show efficacy and safety in the treatment of moderate-to-severe psoriasis.

OBJECTIVE

To investigate drug survival in patients with psoriasis treated with biologics.

PATIENTS AND METHODS

We performed a comparative evaluation of the achievement of PASI 90 and PASI ≤ 3 at 16, 28, and 52 weeks along with a DS (drug survival) analysis with IL-17 and IL-23 inhibitors brodalumab, ixekizumab, secukinumab, risankizumab, tildrakizumab, and guselkumab on 1,057 patients.

RESULTS

IL-17 inhibitors showed a faster achievement of PASI 90 and PASI ≤ 3 with significant superiority over IL-23 inhibitors at week 16 (p < 0.001; 56% vs. 42% and 70% vs. 59%, respectively). A difference was shown in favor of IL-23 inhibitors regarding DS (p < 0.001), which was 88% at 24 months vs. 75% for IL-17 inhibitors. In multivariate analysis, IL-23 inhibitors (HR 0.54 CI 0.37-0.78, p = 0.001), and male sex (HR 0.57 CI 0.42-0.76, p < 0.001) were all associated with a lower probability of drug interruption. Risankizumab (HR 0.42 CI 0.26-0.69, p = 0.001), guselkumab (HR 0.49 CI 0.24-0.99, p = 0.046), and male sex (HR 0.57 CI 0.43-0.77, p < 0.001) were associated with a lower probability of drug interruption than secukinumab.

CONCLUSIONS

IL-23 inhibitors showed the best performance on DS. Overall, the most effective class was IL-17 inhibitors considering the short-term effectiveness, but long-term effectiveness is in favor of anti-IL-23.

Durability and long-term outcomes of biologic therapies in psoriasis

INTRODUCTION

Significant advances in psoriasis treatment have taken place since the introduction of biologics. Tumor necrosis factor inhibitors were the first class of biologics approved and at that time greatly improved psoriasis treatment. However, newer biologics, directed to interleukin(IL)-23/IL-17 pathways central to psoriasis pathogenesis, have improved complete or nearly complete clearance rates and are characterized by an excellent safety profile.Real-world setting experiences have generally confirmed the results of clinical trials, but real-world data regarding newer biologics is relatively scarce.

AREAS COVERED

We provide an extensive review of real-world survival of biologic treatments for moderate to severe psoriasis.

EXPERT OPINION

There is growing and consistent evidence of higher drug survival of IL-23 inhibitors, possibly due to their favorable efficacy and safety profiles, dosing convenience and persistence of response despite treatment interruption; eventual confirmation of their potential role as modifiers of the natural history of psoriasis might provide additional reasons for therapeutic persistence of this class of biologics.

Drug survival und klinische Wirksamkeit von Secukinumab, Ixekizumab, Brodalumab, Guselkumab, Risankizumab und Tildrakizumab in der Behandlung der Psoriasis: Drug survival and clinical effectiveness of secukinumab, ixekizumab, brodalumab, guselkumab, risankizumab, tildrakizumab for psoriasis treatment

Hintergrund

Biologika, die die Interleukine IL‐23 and IL‐17 hemmen, haben sich in der Behandlung der mittelschweren bis schweren Psoriasis als sicher und wirksam erwiesen.

Studienziel

Medikamenten‐Überleben bei Patienten mit Psoriasis zu untersuchen, die mit Biologika behandelt werden.

Patienten und Methoden

Wir haben die Erreichung des PASI 90 und PASI ≤3 nach 16, 28, and 52 Wochen im Vergleich der IL‐17‐ und IL‐23‐Inhibitoren Brodalumab, Ixekizumab, Secukinumab, Risankizumab, Tildrakizumab und Guselkumab bei insgesamt 1057 Patienten untersucht sowie eine Drug Survival‐Analyse durchgeführt.

Ergebnisse

Unter IL‐17‐Inhibitoren wurden PASI 90 und PASI ≤3 schneller erreicht; nach 16 Wochen waren sie den IL‐23‐Inhibitoren signifikant überlegen (p <0,001; 56% vs. 42% beziehungsweise 70% vs. 59%). Im Drug Survival zeigte sich allerdings ein Vorteil für die IL‐23‐Inhibitoren; dieses betrug nach 24 Monaten 88% im Gegensatz zu 75% für die IL‐17‐Inhibitoren (p <0,001). In der multivariaten Analyse waren die IL‐23‐Inhibitoren (HR 0,54 CI 0,37–0,78, p =  0,001) sowie männliches Geschlecht (HR 0,57 CI 0,42–0,76, p <0,001) mit einer geringeren Wahrscheinlichkeit des Absetzens der Medikation assoziiert. Risankizumab (HR 0,42 CI 0,26‐0,69, p =  0,001), Guselkumab (HR 0,49 CI 0,24–0,99, p =  0,046) und männliches Geschlecht (HR 0,57 CI 0,43–0,77, p <0,001) waren mit geringerer Wahrscheinlichkeit des Absetzens der Medikation assoziiert als Secukinumab.

Schlussfolgerung

IL‐23‐Inhibitoren zeigten bezüglich des Drug Survival die besten Ergebnisse. Auf kürzere Sicht waren die IL‐17‐Inhibitoren wirksamer, aber die Langzeitergebnisse sprechen eher für die IL‐23‐Inhibitoren.

Effectiveness and safety of brodalumab in the treatment of plaque, scalp and palmoplantar psoriasis: A multicentre retrospective study in a Spanish population

BACKGROUND AND OBJECTIVE

The data in clinical practice regarding the effectiveness and safety of brodalumab in psoriasis are scarce, especially at scalp and palmoplantar locations. The main objective was the percentage of patients achieving absolute PASI ≤3/ ≤1/ =0 for plaque psoriasis and the percentage of patients achieving an IGA 0-1/IGA 0 for the special locations at Week 52 of treatment.

PATIENTS AND METHODS

Observational retrospective multicentre study in 28 Spanish Hospitals that included adult patients with plaque psoriasis treated with brodalumab, from September 2018 until March 2021.

RESULTS

A total of 200 patients were included. The mean baseline PASI was 10.97 (±6.28) with a mean basal scalp (n = 58) and palmoplantar (n = 40) IGA of 2.10 (±0.97) and 2.15 (±1.26), respectively. At Week 52, 93.98%/75.90%/68.67% of patients reached an absolute PASI ≤3/ ≤1/ =0 in plaque psoriasis (n = 83), with a percentage of patients achieving scalp (n = 27) and palmoplantar (n = 19) IGA 0-1/IGA 0 of 96.3%/88.9% and 100%/88.9%, respectively. Fifteen per cent of patients reported any adverse events with candidiasis being the most reported (6%), but only 6% of the adverse events required the withdrawal.

CONCLUSIONS

Brodalumab demonstrated high PASI and IGA responses and was well tolerated in clinical practice in plaque, scalp and palmoplantar psoriasis.

Brodalumab for the treatment of plaque psoriasis in a real-life setting: a 3 years multicenter retrospective study-IL PSO (Italian landscape psoriasis)

Introduction

Brodalumab is a monoclonal antibody that targets the subunit A of the interleukin-17A receptor (IL17RA), inhibiting the signaling of various isoforms of the IL-17 family. It has been approved for the treatment of moderate-to-severe plaque psoriasis after being evaluated in three Phase-3 trials. However, long-term data on brodalumab in a real-life setting are still limited.

Methods

The aim of this study was to evaluate the long-term effectiveness and safety of brodalumab in psoriasis. We also assessed the drug survival of brodalumab in a 3 years timespan. We conducted a retrospective multicenter study on 606 patients followed up at 14 Italian dermatology units, all treated with brodalumab according to Italian guidelines. Patients' demographics and disease characteristics were retrieved from electronic databases. At baseline and weeks 12, 24, 52, 104 and 156, we evaluated the psoriasis area and severity index (PASI) score and investigated for adverse events. The proportions of patients reaching 75, 90 and 100% (PASI 75, PASI 90 and PASI 100, respectively) improvement in PASI, compared with baseline, were also recorded.

Results

At week 12, 63.53% of the patients reached PASI 90 and 49.17% PASI 100. After 3 years of treatment, 65.22% of patients maintained a complete skin clearance, and 91.30% had an absolute PASI of 2 or less. Patients naïve to biological therapies had better clinical responses at weeks 12, 24 and 52. However, after 2 years of treatment, no significant differences were observed. Body mass index did not interfere with the effectiveness of brodalumab throughout the study. No new safety findings were recorded. After 36 months, 85.64% of our patients were still on treatment with brodalumab.

Conclusion

Our data confirm the effectiveness and the safety of brodalumab in the largest real-life cohort to date, up to 156 weeks.

Long-Term Efficacy, Safety, and Drug Survival of Guselkumab in Patients with Psoriasis: Real-World Data from the Czech Republic BIOREP Registry

BACKGROUND

Real-world data on the long-term use of guselkumab for treatment of psoriasis are still limited.

OBJECTIVE

We aimed to evaluate long-term efficacy, safety, and drug survival of guselkumab in a real-world setting.

METHODS

This is a retrospective study analyzing Czech Republic registry (BIOREP) data of patients treated with guselkumab.

RESULTS

In total, 333 patients were included. Improvement in Psoriasis Area and Severity Index (PASI) score was significant. Mean PASI score decreased from 16 at baseline to 0.7, 0.9, and 0.8 after 12, 24, and 36 months, respectively. Absolute PASI scores of ≤ 3 and ≤ 1 were achieved in 93.9% and 77.9%, 94.2% and 71.0%, and 94.8% and 70.7% of patients after 12, 24, and 36 months, respectively. Response PASI 90 and PASI 100 were attained in 81.8% and 57.1%, 75.4% and 50.7%, and 75.9% and 55.2% of patients after 12, 24, and 36 months, respectively. The percentage of patients achieving PASI 90 and PASI 100 responses was higher throughout the study in bio-naive and in normal-weight patients, while presence of psoriatic arthritis had no influence. Improvement in Dermatology Life Quality Index (DLQI) score was also significant; mean DLQI score decreased from 14.2 at baseline to 0.9, 1.0, and 0.7 after 12, 24, and 36 months, respectively. Patients with PASI 100 had lower mean DLQI throughout the study compared with patients with PASI 90. Major reason for discontinuation was loss of effectiveness in 7.1% of patients, while only 0.6% were due to adverse events. Overall cumulative drug survival was high, with only a minimal decline over time, reaching 91.6%, 87.0%, and 85.5% after 12, 24, and 36 months, respectively. Drug survival was not affected by previous biological treatment, patient weight, or presence of psoriatic arthritis.

CONCLUSIONS

This real-world study demonstrated the long-term effectiveness, good safety profile, and high drug survival of guselkumab treatment over a period of 36 months.

Why targeted therapeutics have provided benefit in psoriasis: looking at IL-17 biology

INTRODUCTION

Psoriasis is an inflammatory, chronic and immune-mediated disease that can affect the skin and joints. Pro-inflammatory cytokines have a dominant role in the pathogenesis of this heterogeneous disease in which the IL-23/IL-17 axis plays a crucial role. The IL-17 family is involved in numerous processes such as immune defense, intestinal disorders and diseases of the central nervous system. In psoriasis, in particular, many cytokines belonging to the IL-17 family are involved in the inflammatory cascade underlying the disease.

AREAS COVERED

The knowledge of the mechanisms and pathways behind psoriasis is crucial for the development of new target therapies. We focused on IL-17 biology in order to understand why biological drugs against this cytokine are an effective treatment for moderate to severe psoriasis. Clinical trials results of ixekizumab, brodalumab, secukinumab and bimekizumab have been presented.

EXPERT OPINION

Il-17 inhibitors are a very fast and effective treatment against psoriasis; however, fungal infections can occur during their use, due to IL-17 biological functions. Therefore, it should be mandatory to choose the right patients to treat with these monoclonal antibodies in order to have a tailored target therapy for each patient.

Real-world clinical outcomes of treatment with brodalumab in patients with moderate-to-severe psoriasis: a retrospective, 24-month experience from four academic dermatology centers in Greece

OBJECTIVE

To assess the real-world clinical treatment outcomes with brodalumab in patients with moderate-to-severe plaque psoriasis in Greece.

MATERIALS AND METHODS

This was a longitudinal, retrospective, real-world analysis of data from medical records of 106 patients with moderate-to-severe plaque psoriasis, treated with brodalumab for up to 24 months at four University Dermatology Centers in Greece. Efficacy assessments of psoriasis severity [Psoriasis Area and Severity Index (PASI) and Body Surface Area affected (BSA) scores] and its impact on patients' quality of life (QoL) [Dermatology Life Quality Index (DLQI) score] were evaluated at different timepoints up to 24 months.

RESULTS

Treatment with brodalumab reduced both mean PASI (14.0-1.5, p < .001) and BSA scores (21.6-2.5, p < .001) across all visits. This effect was accompanied by reduction in mean DLQI score (12.8-2.1, p < .001) across all visits compared with baseline. Moreover, therapeutic efficacy was affected by prior biologic treatment exposure, as biologic naïve patients had greater reductions in all scores from baseline following treatment with brodalumab (numerical for mean PASI, significant for mean BSA and DLQI scores).

CONCLUSION

Brodalumab is effective long term, improving disease severity and health-related QoL in patients with moderate-to-severe plaque psoriasis in a real-world setting.
