Secukinumab in the Treatment of Psoriasis: A Narrative Review on Early Treatment and Real-World Evidence.

Psoriasis is a chronic, immune-mediated, inflammatory skin disease, associated with multiple comorbidities and psychological and psychiatric disorders. The quality of life of patients with this disease is severely compromised, especially in moderate-to-severe plaque psoriasis. Secukinumab, a fully humanized monoclonal antibody, was the first anti-interleukin (IL)-17 biologic approved for treating psoriasis. Secukinumab demonstrated long-lasting efficacy and a good safety profile in individuals with plaque psoriasis, and it is associated with an improvement in health-related quality of life. While there is evidence that early treatment with systemic therapy can affect disease progression and improve long-term outcomes in other autoimmune diseases, evidence is limited in psoriasis, especially in real-world settings. This review provides an overview of studies describing the effectiveness of secukinumab in the treatment of psoriasis summarizing the literature and focusing on real-world evidence and early intervention.

Do interleukin-17 and interleukin-23 inhibitors alter the coagulation parameters in psoriasis patients?: A retrospective study.

Psoriasis is a chronic inflammatory skin condition associated with systemic inflammation and a higher risk of cardiovascular comorbidities. This study retrospectively evaluates coagulation parameters in psoriasis vulgaris patients treated with IL-17 inhibitors (secukinumab, ixekizumab) and IL-23 inhibitors (risankizumab, guselkumab), compared to those untreated systemically. The study reviewed records from 177 patients treated between January 2019 and March 2023. Patients were grouped into control (n = 77), secukinumab (n = 36), ixekizumab (n = 19), guselkumab (n = 24), and risankizumab (n = 21). Coagulation parameters, including PT, aPTT, PLT, MPV, INR, fibrinogen, D-dimer, and B12 levels, were analyzed. The primary endpoint was the comparison of coagulation parameters between groups. Significant differences were found in PT, with secukinumab-treated patients showing a significantly shorter PT compared to controls (p = 0.002). No significant differences were observed in other coagulation parameters across the groups. The study highlights a potential effect of secukinumab on coagulation pathways, possibly related to IL-17's role in inflammation and endothelial function. Despite current literature suggest a risk of cerebrovascular events with risankizumab, this study did not show any significant changes in coagulation parameters with risankizumab, indicating no hypercoagulability risk associated with this IL-23 inhibitor. Our findings suggest IL-17 and IL-23 inhibitors are generally safe concerning coagulation parameters, but regular monitoring may be warranted for patients on secukinumab due to its effect on PT. Further long-term studies are needed to fully understand the cardiovascular risks associated with these therapies.

Secukinumab Ameliorates Oxidative Damage Induced by Subarachnoid Hemorrhage

This study aimed to investigate the histological and biochemical neuroprotective effects of secukinumab (SEC) on brain damage induced by subarachnoid hemorrhage (SAH) in male Wistar Albino rats. Forty male Wistar Albino rats were randomly divided into 4 groups of equal size: control, SEC, SAH, and SAH+SEC. SAH was induced the SAH and SAH+SEC groups by injecting autologous blood collected from the hearts of the rats into the subarachnoid space via the foramen magnum. SEC was administered intraperitoneally once a week to the SEC and SAH+SEC groups after the surgical procedure. On the 14th day of surgery, the rats were sacrificed and their cerebral tissues were collected for biochemical analysis and histopathological examination. SAH led to changes in oxidative stress parameters by increasing malondialdehyde levels and decreasing superoxide dismutase, glutathione, catalase, and glutathione peroxidase levels. Histopathologically, cerebral tissues in the SAH groups showed alterations such as congestion and cell infiltration. Treatment with SEC significantly reduced malondialdehyde levels and increased superoxide dismutase, glutathione, catalase, and glutathione peroxidase levels. SEC also decreased histopathological alterations in brain tissues. This study revealed that SEC (3mg/kg) therapeutically influenced oxidative and histopathological changes in blood parameters and brain tissues caused by experimental SAH. SEC helps reduce brain damage in rats with SAH and possesses antioxidant and neuroprotective properties. Further advanced studies are needed to prove its potential benefits for humans.

Drug Survival, Safety, and Effectiveness of Secukinumab for up to 5 Years in Patients with Psoriasis and Psoriatic Arthritis: A Long-Term Real-Life Experience.

the selective IL-17 inhibitor secukinumab has demonstrated efficacy and safety in the treatment of moderate-severe psoriasis in recent years. evaluate effectiveness and drug survival (DS) of secukinumab in patients with psoriasis for up to 5 years. This is a retrospective study on a monocentric cohort of patients with psoriasis on secukinumab evaluating the achievement of PASI100, PASI90, and PASI ≤ 3 and DS analysis up to 260 weeks. DS multivariate analysis was carried out considering sex, age, age of onset of the disease, obesity, cardiovascular comorbidities, diabetes, involvement of difficult-to-treat sites, psoriatic arthritis, treatment-naïve status, and mean baseline PASI. At baseline, we evaluated 255 patients on secukinumab. PASI100 was reached by 41.7% and 70.6% of patients at weeks 16 and 260, respectively. PASI90 showed a similar trend with 46.5% of patients achieving it at week 16 and 88.2% at week 260. Non-obese patients showed a faster response than patients with obesity in achieving PASI100, PASI90, and PASI ≤ 3, with significant differences at 28 weeks [55% vs. 40% (p = 0.033), 64% vs. 49% (p = 0.038), and 76% vs. 62% (p = 0.036), respectively]. The estimated DS for secukinumab was 84.3% at 12 and 48% at 60 months. Obesity and smoking habits were associated with a higher risk of discontinuation in multivariate models (HR 1.6 CI 1.05-2.45, p = 0.028; HR 1.48 CI 1.01-2.17, p = 0.043, respectively). Secukinumab showed effectiveness for up to 5 years of treatment, with a high DS and achievement of PASI100, PASI90, and PASI < 3 at these time points. Only obesity reduced the response and maintenance of DS.

Long-Term Persistence Rate of Secukinumab in Psoriatic Patients: A Six-Year Multicenter, Real-World Experience, Retrospective Study.

Background: Psoriatic disease, a chronic immune-mediated systemic inflammatory condition, significantly impairs patients' quality of life. The advent of highly targeted biological therapies has transformed treatment strategies, emphasizing the importance of selecting the most effective and cost-efficient option. Secukinumab, an IL-17A inhibitor, has demonstrated efficacy and safety in treating moderate-to-severe plaque psoriasis (PsO). However, long-term real-world data on its effectiveness and persistence rate are limited. Methods: This retrospective study, conducted across eight Italian dermatology centers, aimed to evaluate the 6-year persistence rate and effectiveness of secukinumab in patients with PsO. Additionally, the study investigated the onset of psoriatic arthritis during treatment. Results: Overall, 166 adult patients were analyzed. Their median age was 53.9 years. The mean BMI was 26.5. Of the 166 patients, 64 were bio-experienced while 102 were bio-naïve. A progressive reduction in PsO severity measured by PASI scores over 6 years of treatment was revealed: the PASI score decreased from a baseline value of 18.1 (±9.1) to 0.7 (±1.6) after 6 years of follow-up. Adverse events, including mucocutaneous fungal infections and cardiovascular disturbances, were reported in 19.9% of patients. The persistence rate was 86.8% at 24 months, decreasing to 66.4% at 72 months. Psoriatic arthritis onset during treatment was observed in 15 (9.0%) of patients. Conclusions: This study highlights the sustained effectiveness and favorable safety profile of secukinumab over 6 years, providing valuable real-world evidence. Understanding the long-term persistence rate and predictors of discontinuation could help clinicians optimize treatment decisions and improve patient outcomes in PsO management. We found that the absence of scalp PsO, no involvement of the genital area and normal weight were the best factors of persistence in secukinumab treatment in the long term.

Effectiveness and safety of secukinumab updosing in patients with moderate to severe plaque psoriasis: data from the PURE registry

Secukinumab is a fully human IgG1 antibody that selectively binds to and neutralizes the proinflammatory cytokine interleukin-17A. Secukinumab is an effective and well-tolerated treatment for plaque psoriasis. There is a limited real-word evidence for dose optimisation of secukinumab based on clinical response. PURE is a multi-national, 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 indicated therapies. The aim of the current snapshot analysis was to evaluate the effectiveness and safety of on-label dose and updosed secukinumab in patients with plaque psoriasis enrolled in the PURE study. At the time of analysis, 676 patients received secukinumab, of which 84.6% (n = 572) remained on the on-label dose, while 15.4% (n = 104) were updosed. With on-label secukinumab, the absolute Psoriasis Area and Severity Index (PASI) score was reduced from 13.6 at baseline to 1.2 over 36 months, with treatment persistence of 73% at 40 months. At Month 36, 73.2% of the patients receiving on-label secukinumab achieved Investigator’s Global Assessment (IGA) 0/1. With updosed secukinumab (300 mg every 2 weeks, 300 mg every 3 weeks, 450 mg every 4 weeks, or 450 mg every 3 weeks), 57.9% of the patients showed improvement in the absolute PASI score at the first visit after updosing, with treatment persistence of 50% at 12 months after updosing. At Month 15, 40% of patients receiving updosed secukinumab achieved IGA 0/1. Patients with previous biologic exposure (odds ratio [OR]: 3.25; 95% confidence interval [CI]: 2.03, 5.18, p < 0.0001) were more likely to be updosed while those with a body weight < 90 kg (OR: 0.49; 95% CI [0.31, 0.77], p = 0.0019) were less likely to be updosed. Previous biologic exposure (HR [hazard ratio]: 1.47; 95% CI [1.24, 1.75], p < 0.0001) and current biologic exposure (secukinumab vs. other indicated therapies: HR 0.57; 95% CI [0.43, 0.75], p = 0.0001) were significantly associated with time to secukinumab updosing. No new or unexpected safety signals were observed with updosed secukinumab. Secukinumab updosing was efficacious and well-tolerated in patients with psoriasis who failed to respond to the approved on-label regimen, suggesting that updosing may be a useful therapeutic option for approved dose non-responders.

Effectiveness of secukinumab for overlapping hidradenitis suppurativa and ankylosing spondylitis

AbstractHidradenitis suppurativa is a chronic inflammatory disease of the hair follicle that affects the axillary and gluteal regions. Hidradenitis can coincide with other inflammatory diseases, such as ankylosing spondylitis. We present a patient suffering from an overlap of both conditions, who had a rapid improvement with secukinumab.

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

IntroductionPsoriasis (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.MethodsThis 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.ResultsThe 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%.ConclusionIn a Saudi real-world setting, secukinumab proved to be an efficient medication with high efficacy and retention rates.

Drug Survival, Effectiveness and Safety of Secukinumab in Axial Spondyloarthritis up to 4 Years: A Real-Life Single Center Experience.

(1) Objective: The main aims of our study were to explore the drug survival and effectiveness of secukinumab in patients with axial spondyloarthritis (axSpA). (2) Methods: We underwent a retrospective analysis of consecutive axSpA treated with secukinumab as a first line of biologics or at switch in a biologic-experienced population. Efficacy data, indicating improvement in inflammation parameters (such as C-reactive protein and erythrocyte sedimentation rate) and disease activity scores (such as Ankylosing Spondylitis Disease Activity Score [ASDAS-CRP], Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]), and patient-reported outcomes (pain), were assessed at 6, 12, 24, 36 and 48 months. The drug survival rate, dropout rate and discontinuation reasons (efficacy versus safety) of secukinumab were assessed in subgroup analysis (axSpA with and without exposure to biologics). (3) Results: In total, 46 patients were exposed to the IL-17A inhibitor secukinumab. The drug survival for axSpA patients 59.7% at 12 months and 31.3% at 24 months. There were no statistically significant differences in the median drug survival between biologic-naïve versus biologic-experienced subgroups. (4) Conclusions: Secukinumab has demonstrated effectiveness and safety in treating a cohort of axSpA patients in real-world settings, with a notable retention rate of the drug.

Targeting Common Inflammatory Mediators in Experimental Severe Asthma and Acute Lung Injury.

Neutrophils, known to be mobilized and activated in high amounts through Il-17 stimulation, are a key factor for clinical manifestation and imbalance of redox systems favoring a dominant oxidative state in both severe asthma and acute lung injury (f). The aim of this study was to evaluate in mice, the effect of Secukinumab (SECU) in a model of ovalbumin-induced asthma exacerbated with LPS administration to induce ALI, compared to dexamethasone (DEXA), already known for its benefit in both asthma and ALI. Results on cytokine levels for specific Th1, Th2 and Th17 revealed an interplay of immune responses. For Th1 effector cytokines in BALF, DEXA treatment increased TNF-α levels, but TNF-α was not modified by SECU; DEXA and SECU significantly decreased IFN-γ and IL-6 levels. For typical Th2 cytokines, DEXA significantly increased Il-4, Il-5 and Il-13 levels, while SECU significantly inhibited Il-5 levels. Both SECU and DEXA significantly decreased Il-17 levels. Cytokine level changes in lung tissue homogenate were partly similar to BALF cytokines. Conclusion: in addition to DEXA, SECU possesses the ability to modulate inflammatory cytokine release and to decrease Th17 responses in ALI overlapped on exacerbated asthma in mice.

Deep resolution of clinical, cellular and transcriptomic inflammatory markers of psoriasis over 52 weeks of interleukin-17A inhibition by secukinumab.

Secukinumab, an anti-interleukin (IL)-17A monoclonal antibody, induces histological and molecular resolution of psoriatic plaques by 12 weeks. However, the long-term effects of secukinumab on the molecular resolution of psoriatic inflammation remain unknown. To investigate the molecular resolution of psoriasis following 52 weeks of secukinumab treatment. This was a two-part phase II randomized double-blinded placebo-controlled 52-week study of patients with moderate-to-severe psoriasis receiving secukinumab 300 mg (NCT01537432). Psoriatic lesional and nonlesional skin biopsies were obtained at baseline and at weeks 12 and 52, and the composition of the residual disease genomic profile (RDGP; i.e. 'molecular scar') of biopsies from secukinumab responders analysed. After 52 weeks of treatment, 14 of 24 enrolled patients were considered to be clinical responders [≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75)], 4 of 24 were considered to be nonresponders (< PASI 75) and 6 of 24 patients were lost to follow-up; both the histological and transcriptomic profiles of PASI 75 responders improved from week 12 to week 52. RDGP transcripts of histological responders only partially overlapped between weeks 12 and 52, despite a similar number of transcripts in each RDGP; specifically, four novel transcript subsets showed distinct expression dynamics between weeks 12 and 52 ('slow-resolving', 'recurring', 'persistent' and 'resolved'), with anti-inflammatory and immunomodulatory genes (e.g. SOCS1, CD207 and IL37) notably restored at week 52. Shorter disease duration prior to secukinumab treatment coincided with greater transcript improvements at weeks 12 and 52. Secukinumab improves the histological and molecular phenotype of psoriatic lesional skin up to 52 weeks of treatment; these results suggest possible mechanisms that drive long-term control of psoriasis.

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

Secukinumab, a fully human monoclonal antibody, was approved in Korea for the treatment of moderate to severe psoriasis in September 2015. To assess the safety and effectiveness of secukinumab in patients with moderate to severe psoriasis in Korea. Multicenter, real-world, noninterventional study conducted over 6 years. 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. 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. Secukinumab showed sustained effectiveness and favorable safety profile in adult patients with moderate to severe psoriasis in Korea.

Efficacy and NSAID-sparing effect of secukinumab 150 mg in ankylosing spondylitis: results from phase IV ASTRUM study

Efficacy and NSAID-sparing effect of secukinumab 150 mg in ankylosing spondylitis: results from phase IV ASTRUM study

Effects of secukinumab combined with tretinoin on metabolism, liver enzymes, and inflammatory factors in patients with moderate to severe psoriasis vulgaris.

Psoriasis is a T cell-mediated polygenic chronic inflammatory disease. Interleukin (IL)-17A plays a major role in psoriasis pathogenesis. Secukinumab is a high-affinity human monoclonal antibody against IL-17A. This article explored efficacy and safety of secukinumab plus tretinoin in moderate to severe psoriasis (MSP) vulgaris, and assessed metabolism, liver function, and inflammation. A total of 135 patients diagnosed with moderate or severe psoriasis vulgaris were enrolled and randomized into three groups at a 1 : 1 : 1 ratio, receiving treatment with rretinoin, secukinumab, or combination therapy for a duration of 16 weeks. Psoriasis area and severity index (PASI) scores, serum T lymphocyte subsets, glucose, lipid, and uric acid (UA) metabolism, liver enzymes, and inflammatory factors (IFs) were measured. Following the therapy, subjects had decreased PASI scores, increased serum CD3+, CD4+, and CD4+/CD8+, decreased serum CD8+, and decreased serum UA and IL-2, IL-6, IL-23, interferon-γ (IFN-γ), and tumor necrosis factor (TNF)-α (p < 0.05). Total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, apolipoproteins A1, B, fasting blood glucose, alanine transaminase, aspartate transaminase, and alkaline phosphatase had no obvious differences among the subjects (p > 0.05). As against the Tretinoin and the Secukinumab groups, the PASI score was visiblysmaller, the changes in serum T lymphocyte subsets were more obvious, and serum UA and IFs were lower in the Combination group following the therapy (p < 0.05). Secukinumab combined with tretinoin is more effective in MSP vulgaris, which can visibly reduce inflammatory response without affecting glucose and lipid metabolism and liver function.

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.

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

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

Biologics targeting IL-23 and IL-17 show efficacy and safety in the treatment of moderate-to-severe psoriasis. To investigate drug survival in patients with psoriasis treated with biologics. We performed a comparative evaluation of the achievement of PASI90 and PASI ≤ 3 at 16, 28, and 52weeks 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. IL-17 inhibitors showed a faster achievement of PASI90 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. 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.

Effect of Secukinumab and Tumor Necrosis Factor Inhibitors on Humoral Response to BNT162b2 mRNA Vaccine in Patients With Spondyloarthritis Compared to Immunocompetent Controls.

To assess the humoral response to the BNT162b2 mRNA vaccine among patients with spondyloarthritis (SpA) receiving secukinumab (SEC) compared to those receiving tumor necrosis factor inhibitors (TNFi) and immunocompetent controls. Consecutive patients with psoriatic arthritis or axial SpA receiving SEC (n = 37) or TNFi (monotherapy, n = 109; + methotrexate [MTX], n = 16), immunocompetent controls (n = 122), and patients with rheumatoid arthritis (RA) receiving TNFi therapy (controls, n = 50) were vaccinated with 2 or 3 doses of the BNT162b2 vaccine. We evaluated humoral response, adverse events, and disease activity, and monitored for breakthrough coronavirus disease 2019 (COVID-19) postvaccination. The 2-dose vaccine regimen induced a comparable seropositive response in all study groups. S1/S2 antibody titers (in binding antibody units/mL; mean [SD]) were higher in the SEC group vs the TNFi + MTX-SpA and TNFi-RA groups (192.5 [68.4] vs 104.6 [46.9], P < 0.001, and 143.1 [81.9], P = 0.004). After 6 months, 96.3%, 96.6%, and 80.9% of the SEC, immunocompetent, and TNFi monotherapy-SpA groups (P = 0.10), respectively; 66.7% of the TNFi + MTX-SpA group (P = 0.03); and 63% of the TNFi-RA group (P = 0.004) remained seropositive. S1/S2 antibody titer decline was steeper in the TNFi groups than the SEC group. After the third dose, 100% of the SpA and immunocompetent and 88.9% of the TNFi-RA (P = 0.25) groups were seropositive. Rate of breakthrough COVID-19 infection was higher in the TNFi groups than in the SEC group (36-37.5% vs 10.8%). No significant between-group differences were observed for postvaccination disease activity and adverse events. SEC did not interfere with the immunogenic response to BNT162b2 vaccine in patients with SpA; however, TNFi therapy was associated with lower S1/S2-antibody titers, faster decline, and higher rate of breakthrough infections.

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.

Effects of secukinumab on synovitis and enthesitis in patients with psoriatic arthritis: 52-week clinical and ultrasound results from the randomised, double-blind ULTIMATE trial with open label extension

ObjectivesIn the ULTIMATE study with an open label extension, we assessed the long-term effect of secukinumab at tissue level on synovitis and enthesitis, and across all psoriatic arthritis (PsA) manifestations, using both clinical evaluations and power Doppler ultrasonography (PDUS). MethodsThis randomised, placebo-controlled, Phase 3 study (ULTIMATE) included biologic-naïve patients with PsA with active PDUS synovitis and clinical enthesitis, and inadequate response to conventional synthetic disease-modifying antirheumatic drugs. The study consisted of 3 treatment periods; in the first period (baseline to week 12) patients were randomised to receive subcutaneous secukinumab (150 mg or 300 mg according to severity of skin psoriasis) or placebo every week until week 4 and once every 4 weeks up to week 12. In the second period (weeks 12–24) all patients received open-label secukinumab with placebo patients switching to secukinumab (150 mg or 300 mg). The third period (weeks 24–52) was an extended open-label treatment period. The long-term responsiveness of the Global EULAR-OMERACT Synovitis Score (GLOESS), clinical enthesitis and global PDUS-detected enthesitis score (using two candidate definitions of activity) at patient level, together with clinical efficacy across key manifestations of PsA and safety were assessed. ResultsOf the 166 patients enrolled, 144 completed week 52. A significant reduction in GLOESS was demonstrated in the secukinumab group vs placebo at week 12, followed by a stable reduction of synovitis until week 52 in the secukinumab group while placebo switchers from week 12 reached a similar level of reduction at week 24 with stability thereafter. Likewise, a significant reduction in the Spondyloarthritis Research Consortium of Canada (SPARCC) enthesitis index was shown in the secukinumab group vs placebo at week 12 with sustained improvement to week 52. Global OMERACT PDUS enthesitis scores were numerically lower in secukinumab vs placebo switchers in the first two treatment periods, with some stability in the third period in both groups. Improvements in clinical responses were also observed across all key domains of PsA up to week 52 in both treatment groups with no new or unexpected safety signals. ConclusionsULTIMATE showed consistent improvements in clinically and ultrasound-assessed synovitis and enthesitis and sustained clinical efficacy through week 52 in patients with PsA treated with secukinumab and placebo switched to secukinumab.
