RESUMEN
Purpose: SUPREME, a phase IIIb study conducted in Italy, demonstrated safety and high efficacy of secukinumab for up to 72 weeks in patients with moderate-to-severe plaque-type psoriasis. SUPREME 2.0 study aimed to provide real-world data on the long-term drug survival and effectiveness of secukinumab beyond 72 weeks. Patients and Methods: SUPREME 2.0 is a retrospective observational chart review study conducted in patients previously enrolled in SUPREME study. After the end of the SUPREME study, eligible patients continued treatment as per clinical practice, and their effectiveness and drug survival data were retrieved from medical charts. Results: Of the 415 patients enrolled in the SUPREME study, 297 were included in SUPREME 2.0; of which, 210 (70.7%) continued secukinumab treatment throughout the 42-month observation period. Patients in the biologic-naïve cohort had higher drug survival than those in the biologic-experienced cohort (74.9% vs 61.7%), while HLA-Cw6-positive and HLA-Cw6-negative patients showed similar drug survival (69.3% and 71.9%). After 42 months, Psoriasis Area and Severity Index (PASI) 90 was achieved by 79.6% of patients overall; with a similar proportion of biologic-naïve and biologic-experienced patients achieving PASI90 (79.8% and 79.1%). The mean absolute PASI score reduced from 21.94 to 1.38 in the overall population, 21.90 to 1.24 in biologic-naïve and 22.03 to 1.77 in biologic-experienced patients after 42 months. The decrease in the absolute PASI score was comparable between HLA-Cw6-positive and HLA-Cw6-negative patients. The baseline Dermatology Life Quality Index scores also decreased in the overall patients (10.5 to 2.32) and across all study sub-groups after 42 months. Safety was consistent with the known profile of secukinumab, with no new findings. Conclusion: In this real-world cohort study, secukinumab showed consistently high long-term drug survival and effectiveness with a favourable safety profile.
RESUMEN
Purpose: Secukinumab is a fully human monoclonal antibody that inhibits interleukin (IL)-17A approved for the treatment of moderate to severe plaque psoriasis in adults and children. We compared the efficacy and safety of secukinumab in patients aged < 65 years (adult patients) versus patients aged ≥ 65 years (elderly patients) in a post-hoc analysis of the SUPREME study. Patients and Methods: Patients with moderate to severe plaque psoriasis received subcutaneous secukinumab 300 mg per week for the first 5 weeks, then 300 mg per month. We compared the following outcomes in patients aged ≥ 65 years vs < 65 years: baseline characteristics; PASI50/75/90/100 response rates (improvements ≥ 50%/75%/90%/100% in Psoriasis Area and Severity Index (PASI) from baseline); changes in Dermatology Life Quality Index (DLQI); Hospital Anxiety and Depression Scale (HAD-A, HAD-D) score changes; treatment-emergent adverse events (TEAEs). Results: Secukinumab was slightly less effective in elderly patients than in adult patients (response rates at week 16: PASI90, 69.4% vs 80.9%, p = 0.4528; PASI100, 44.4% vs 56.7%, p = 0.8973). Elderly and adult patients showed a similar time course of changes in absolute PASI scores. Patients aged ≥ 65 years had a statistically significantly lower improvement in quality of life (mean DLQI reduction) than patients aged < 65 years at week 16 [-5.4 (±4.3) vs -8.8 (±6.9), p = 0.0065] and at week 24 [-5.3 (±4.4) vs -9.2 (±7.1), p = 0.0038]. Secukinumab treatment resulted in comparable mean reductions in anxiety and depression scores in both cohorts at 24 weeks [HAD-A, -1.3 (±3.3) vs -2.1 (±3.8), p = 0.9004; HAD-D, -1.0 (±3.3) vs -1.5 (±3.1), p = 0.4598]. The frequency of TEAEs in the two cohorts was similar (16.7% vs 14.6%, p = 0.7391). Conclusion: Secukinumab is a valid option for the management of moderate to severe psoriasis in elderly patients.
RESUMEN
BACKGROUND: Recent developments improved outcomes in patients with autoimmune diseases. Biologics were approved as first-line treatment in selected naïve patients with plaque psoriasis (PsO), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA). Among them, secukinumab was most recently approved for treatment of active nr-axSpA in adults. In this work, we assessed the budget impact of new secukinumab treatment options in the Italian market. METHODS: A cross-indication budget impact model was designed to estimate the effects of adding secukinumab in the Italian market from the National Health System perspective over a 3-year period. The model included all adults with PsO, PsA, AS and nr-axSpA, treated with biologics or biosimilars. It compared costs between two scenarios, secukinumab availability or absence, for the four diseases combined and taken individually. A sensitivity analyses was conducted. RESULTS: There were 68,121 adult patients treated with biologics in 2021 and 68,341 in 2023. The budget impact analysis (BIA) on all indications showed a cost reduction of 33.7 million (- 1.5%) over 3 years with the introduction of secukinumab. PsA patients had the highest saving (- 34.9 million), followed by PsO patients (- 7.8 million). Cost saving in PsO patients was balanced by increased budget reported in AS patients (+ 8.0 million). In nr-axSpA patients, secukinumab reported no significant budget increase (+ 1.0%). CONCLUSION: This BIA accounted for the new indication of secukinumab in nr-axSpA patients, reporting no significant changes in the required budget and adding an effective treatment option. Considering all indications, secukinumab is a sustainable treatment option.
RESUMEN
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.
RESUMEN
Secukinumab, a fully human monoclonal antibody, neutralizes interleukin-17A, a cornerstone cytokine driving the multiple manifestations of psoriasis. This post-hoc analysis of the SUPREME study was performed to determine the sustainability of response to secukinumab in terms of Psoriasis Area and Severity Index (PASI) 90 in patients with moderate-to-severe plaque psoriasis. Based on PASI 90 response at week 16, patients were stratified as PASI 90 responders (PASI90R, n = 337) or non-responders (PASI90NR, n = 72). At week 20, 94.2% (n = 295/313) achieved PASI 90/100 response in PASI90R, with response maintained through week 48 (89.6%, n = 189/211). An increased proportion of patients achieved PASI 90/100 response in PASI90NR (week 20: 29.9%, n = 20/67; week 48: 57.1%, n = 20/35). Overall, 64.4% patients achieved absolute PASI score = 0 at week 24 with response sustained to week 48 (66.9%). Secukinumab showed sustained and stable efficacy in maintaining PASI 90 response in patients with moderate-to-severe plaque psoriasis up to week 48.

This study evaluated whether secukinumab treatment for patients with moderate to severe plaque psoriasis correlates with improvements in symptoms of anxiety and depression. SUPREME was a 24-week, phase IIIb, multicentre, prospective study conducted across 50 centres in Italy with an extension period of up to 72 weeks. Assessments used were: Psoriasis Area Sever-ity Index (PASI), Hospital Anxiety and Depression Scale (HADS) - Anxiety (HADS-A), and HADS - Depression (HADS-D) scores and Dermatology Quality Life Index (DLQI). Compared with baseline, a significantly greater proportion of patients who reported moderate to severe clinical symptoms of anxiety or depression (HADS-A or HADS-D ≥ 11) were free of moderate to severe symptoms at weeks 16 and 48. The PASI and DLQI scores reduced over time with secukinumab treatment. Psoriasis treatment with secukinumab for 48 weeks resulted in significantly improved skin clearance and a parallel improvement in symptoms of anxiety and depression, assessed by HADS.

In fragile X syndrome (FXS), sensory hypersensitivity and impaired habituation is thought to result in attention overload and various behavioral abnormalities in reaction to the excessive and remanent salience of environment features that would normally be ignored. This phenomenon, termed sensory defensiveness, has been proposed as the potential cause of hyperactivity, hyperarousal, and negative reactions to changes in routine that are often deleterious for FXS patients. However, the lack of tools for manipulating sensory hypersensitivity has not allowed the experimental testing required to evaluate the relevance of this hypothesis. Recent work has shown that BMS-204352, a BKCa channel agonist, was efficient to reverse cortical hyperexcitability and related sensory hypersensitivity in the Fmr1-KO mouse model of FXS. In the present study, we report that exposing Fmr1-KO mice to novel or unfamiliar environments resulted in multiple behavioral perturbations, such as hyperactivity, impaired nest building and excessive grooming of the back. Reversing sensory hypersensitivity with the BKCa channel agonist BMS-204352 prevented these behavioral abnormalities in Fmr1-KO mice. These results are in support of the sensory defensiveness hypothesis, and confirm BKCa as a potentially relevant molecular target for the development of drug medication against FXS/ASD.

Metabotropic glutamate receptor subtype 5 (mGluR5) is crucially implicated in the pathophysiology of Fragile X Syndrome (FXS); however, its dysfunction at the sub-cellular level, and related synaptic and cognitive phenotypes are unexplored. Here, we probed the consequences of mGluR5/Homer scaffold disruption for mGluR5 cell-surface mobility, synaptic N-methyl-D-aspartate receptor (NMDAR) function, and behavioral phenotypes in the second-generation Fmr1 knockout (KO) mouse. Using single-molecule tracking, we found that mGluR5 was significantly more mobile at synapses in hippocampal Fmr1 KO neurons, causing an increased synaptic surface co-clustering of mGluR5 and NMDAR. This correlated with a reduced amplitude of synaptic NMDAR currents, a lack of their mGluR5-activated long-term depression, and NMDAR/hippocampus dependent cognitive deficits. These synaptic and behavioral phenomena were reversed by knocking down Homer1a in Fmr1 KO mice. Our study provides a mechanistic link between changes of mGluR5 dynamics and pathological phenotypes of FXS, unveiling novel targets for mGluR5-based therapeutics.

Intellectual disability (ID) and autism are present in several neurodevelopmental disorders and are often associated in genetic syndromes, such as Fragile X and Rett syndromes. While most evidence indicates that a genetic component plays an important role in the aetiology of both autism and ID, a number of studies suggest that immunological dysfunctions may participate in the pathophysiology of these disorders. Brain-specific autoantibodies have been detected in the sera of many autistic children and autoimmune disorders are increased in families of children with autism. Furthermore, cytokine imbalance has been reported in children with autism. These results may reflect an inappropriate immune response to environmental factors, such as infectious or toxic exposure. The role of microglia as sensors of pre- and post-natal environmental stimuli and its involvement in the regulation of synaptic connectivity, maturation of brain circuitry and neurogenesis has recently emerged. An abnormal immune response during critical windows of development and consequent abnormal production of neuro-inflammatory mediators may have an impact on the function and structure of brain and can play a role in the pathogenesis of non syndromic autism. Recent evidence suggests an involvement of neuro-inflammation also in syndromic forms of autism and ID. Immune dysregulation has been found in children with Fragile X syndrome and an intrinsic microglia dysfunction has been recently reported in Rett syndrome. The present review summarizes the current literature suggesting that neuro-inflammatory mechanisms may contribute to the pathogenesis of different ID- and autism-associated disorders, thus representing common pathophysiological pathways and potential therapeutic targets.
