Interim 2-Year Analysis from SERENA: A Real-World Study in Patients with Psoriatic Arthritis or Ankylosing Spondylitis Treated with Secukinumab

Safety and effectiveness of secukinumab subcutaneous injection in Japanese patients with psoriasis vulgaris and psoriatic arthritis: A post-marketing surveillance

Secukinumab is the first human monoclonal antibody that targets human interleukin-17A. This open-label, multicenter, uncontrolled, single-arm, prospective observational surveillance evaluated the long-term safety and effectiveness of secukinumab in patients with psoriasis vulgaris and psoriatic arthritis (PsA) in Japan. Of 997 patients whose surveillance forms were collected, 976 were included in the safety analysis and 729 in the effectiveness analysis. Prior to the start of secukinumab treatment, biologics were used in 42.52% of patients for the treatment of conditions including psoriasis. The mean ± standard deviation (SD) duration of secukinumab administration was 288.1 ± 106.51 days and the median (range) was 344.0 (1-365) days. The most commonly used dose per administration was 300 mg in 96.21% (939 patients) and the mean ± SD total number of administrations was 13.6 ± 3.87. Adverse events (AEs), AEs suspected to be related to secukinumab, AEs that led to secukinumab treatment discontinuation, serious AEs, and deaths were reported in 36.17%, 18.85%, 8.09%, 5.84%, and 1.13%, respectively. The proportion of patients with an Investigator's Global Assessment score improvement to 0/1 increased over time from the start of secukinumab treatment to week 24 and remained stable thereafter. The Psoriasis Area and Severity Index 75 response rates and the proportions of patients with a Dermatology Life Quality Index score of 0/1 increased from baseline and were maintained up to week 52. This surveillance did not show any new safety concerns of secukinumab treatment. The effectiveness of secukinumab treatment was observed in patients with psoriasis vulgaris and PsA.

IL-17 inhibitors in axial spondyloarthritis. An overview

INTRODUCTION

The therapeutic armamentarium for spondyloarthritis has expanded considerably in recent years, and there is growing evidence to support the increasing use of IL-17 inhibitors (IL-17i) in axial spondyloarthritis (axSpA).

AREAS COVERED

This literature review provides an update on the role of IL-17 in the pathogenesis of axSpA, efficacy and safety from clinical trials and real-life studies on the use of IL17i in axSpA. We also review the impact of extra-musculoskeletal manifestations on the decision to treat with IL17i and the efficacy of IL17i on structural progression.

EXPERT OPINION

There are still some unanswered questions concerning the use of IL-17i in axSpA in clinical practice such as their respective place in the management of axSpA compared to TNFα inhibitors (TNFi). Their main differences rely on their specific efficacy in extra-articular manifestations such as psoriasis, uveitis, and inflammatory bowel diseases leading to the choice of the best treatment in a given patient. Regarding their real impact on structural progression, the rate of progression under IL-17i appears to be low and presumably similar to TNFi. One final question is the advantage of blocking the two IL-17 isoforms A and F compared to the single inhibition of IL-17A.

Four-year real-world experience of secukinumab in a large Italian cohort of axial spondyloarthritis

Objectives

This study aims to evaluate in a real-life Italian multicenter cohort of axial spondyloarthritis (axSpA) (1) the 4-year effectiveness and safety of secukinumab, (2) the drug retention rate (DRR), and (3) the impact of the line of bDMARDs treatment, subtype of axSpA, and sex on achieving low disease activity (LDA) and very low disease activity (VLDA).

Methods

Consecutive axSpA patients receiving secukinumab between 2016 and 2023 were prospectively evaluated. Data on disease characteristics, previous/ongoing treatments, comorbidities, and follow-up duration were collected. Treatment response was evaluated at 6 and 12 months after initiation and yearly up to 48 months (T48). DRR and effectiveness outcomes were evaluated according to bDMARDs treatment, axSpA subtype, and sex. Infections and adverse events (AEs) were recorded.

Results

We enrolled 272 patients (48.2% male; median age, 51; 39.7% HLA-B27+; 40.4% nr-axSpA), of whom 30.9% were naïve to secukinumab. Overall, secukinumab yielded improvement in effectiveness outcomes; the naïve patients maintained lower disease activity vs. the non-naïve ones. At T48, the LDA and VLDA rates were higher in naïve patients and in male individuals. Treatment was discontinued in 104 patients due to primary/secondary loss of effectiveness and in 34 patients due to AEs. The DRR at T48 was 67.4% in the whole population, regardless of treatment line, axSpA subtype, and sex.

Conclusions

Secukinumab was safe and effective in all axSpA patients irrespective of treatment line, disease subtype, and sex. The patients achieved sustained 4-year remission and DRR.

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.

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.

Real-world effectiveness and persistence of secukinumab in the treatment of patients with psoriatic arthritis

Introduction

Psoriatic arthritis (PsA) is a complex and heterogeneous inflammatory disease. Secukinumab, a biologic disease-modifying antirheumatic drug (bDMARD), has extensive clinical evidence of efficacy and safety in the treatment of PsA but data in clinical practice are still limited. This study aims to provide real-world evidence on secukinumab use, effectiveness, and persistence in PsA.

Methods

A retrospective, multicenter study was conducted on patients diagnosed with PsA and treated with secukinumab up to June 2021 at 12 centers in the Valencian Community (Spain). Data on DAS28-CRP, DAPSA, Tender and Swollen Joint Counts (TJC, SJC), enthesitis, dactylitis, skin and nail involvement, pain, patient and physician global assessment (ptGA, phGA) using 100-mm visual analog scale (VAS), and persistence for up to 24 months were collected.

Results

A total of 178 patients were included (49% men; mean [standard deviation, SD] age: 51.4 [10.5] years; 39% obese). Secukinumab was used as a first-, second-, or ≥ third-line bDMARD in 37, 21, and 42% of patients, respectively. The percentage of patients achieving at least low disease activity (DAS28-CRP ≤ 3.2) increased from 25% at baseline to 66% at month 6 (M6) and was maintained (75%) up to M24. Mean (SD) DAS28-CRP baseline values (3.9 [1.2]) decreased to 2.9 (1.1) (p < 0.001) at M6 and remained low through M24 (2.6 [1.1]) (p < 0.001). Secukinumab also improved peripheral arthritis increasing the percentage of patients with TJC = 0 (20% baseline; 57% M24) and SJC = 0 (37% baseline; 80% M24). Treatment reduced the percentage of patients with enthesitis (25% baseline; 6% M24), dactylitis (20% baseline; 4% M24), and skin (70% baseline; 17% M24), and nail (32% baseline; 2% M24) involvement. Additionally, we observed improvements in the mean pain VAS (-26.4 mm M24), ptGA (-26.2 mm M24), and phGA (-24.8 mm M24). Secukinumab showed an overall 24-month persistence rate of 67% (95% confidence interval [CI]: 60-74%). Patients receiving first-line secukinumab showed the highest 24-month persistence rate (83, 95% CI: 73-92; p = 0.024).

Conclusion

Secukinumab showed long-term effectiveness across the six key PsA domains thus reducing disease activity and pain, which are major treatment goals. This was accompanied by high persistence rates, especially in bDMARD naive patients.

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.
