Baseline characteristics of patients with moderate‐to‐severe psoriasis according to previous systemic treatment exposure: the PROSE study population

Guselkumab-Treated Patients with Plaque Psoriasis Who Achieved Complete Skin Clearance for ≥ 156 Consecutive Weeks: A Post-Hoc Analysis From the VOYAGE 1 Clinical Trial

BACKGROUND

Treatment of moderate-to-severe plaque psoriasis with biologics, such as guselkumab, has demonstrated greater efficacy over traditional non-biologic treatments. However, given patient diversity, greater understanding of the relationship between patient characteristics, positive clinical outcomes, and long-term response to biologics is crucial for optimizing treatment choices.

MATERIALS AND METHODS

This post-hoc analysis of the 5-year VOYAGE 1 clinical trial compares baseline characteristics of patients maintaining a Psoriasis Area and Severity Index (PASI) score of 0 at all visits for ≥ 156 consecutive weeks (PASI = 0 group) with those that never achieve PASI = 0 (comparator group), using descriptive statistics and a multiple logistic regression model. Guselkumab plasma trough concentrations in both response groups were assessed from Weeks 4-156.

RESULTS

Of patients who started guselkumab treatment at Week 0 or at Week 16 after switching from placebo, 22.7% (112/494) maintained PASI = 0 for ≥ 156 consecutive weeks. Numerical differences in baseline characteristics, including age, obesity, diabetes, PASI score, disease duration, smoking status, and psoriatic arthritis comorbidity, were identified between the PASI = 0 group and comparator group. Plasma guselkumab levels were consistently higher in the PASI = 0 group. Multiple logistic regression analysis revealed absence of diabetes, lower Dermatology Life Quality Index score at baseline, and higher Week 4 guselkumab plasma concentration as significantly (p < 0.05) associated with the PASI = 0 group.

CONCLUSION

A substantial (22.7%) number of guselkumab-treated patients in the VOYAGE 1 clinical trial maintained complete skin clearance for a consecutive period of ≥ 156 weeks. Factors associated with this outcome may suggest clinical benefits of holistic treatment approaches.

The Burden of Psoriasis in China and Global Level from 1990 to 2019: A Systematic Analysis from the Global Burden of Disease Study 2019

Objectives

Psoriasis is a skin disease thought to be related to immune system dysfunction. Our study is aimed at analyzing the prevalence of psoriasis in China in multiple different categories and compared the prevalence at the global level, in order to bring insights to policymakers for treating this disease.

Methods

We analyzed psoriasis trends from 1990 to 2019 in China as well as around the globe with data from the Global Burden of Disease 2019 study. Multiple metrics such as age-standardized prevalence rates, percent change in age-standardized prevalence rates, disability-adjusted life years (DALYs), and age and sex patterns were included. We also predicted the trends of psoriasis prevalence and DALYs in the following 30 years.

Results

In China, the age-specific prevalence cases showed a right shift in 2019 compared to 1990 with a peak between the ages of 50 and 54 years and an obvious surpass in males between 40 and 69. Though China still had the largest number of psoriasis cases in 2019, the increase rate was below global level. A positive linear relationship between psoriasis prevalence and comorbidities was seen with rheumatoid arthritis, diabetes mellitus, multiple sclerosis, nonrheumatic valvular heart disease, cardiomyopathy and myocarditis, nonmelanoma skin cancer, non-Hodgkin lymphoma, and multiple myeloma in China within the male group in 2019. Discussion. The burden of psoriasis, as measured by the absolute number of DALYs, continues to increase around the world. The scarcity of modifiable risks for most psoriasis burdens suggests that new knowledge is needed to develop effective prevention and treatment strategies.

Fast and sustained Improvement of Patient-reported outcomes in psoriatic patients treated with secukinumab in a daily practice setting

Psoriasis is a chronic dermatological disease with great impact on patients' quality of life (QoL). The main objective of this study was to assess the impact of secukinumab treatment on different patient-reported outcomes (PROs) during a long-term follow-up in Spanish patients with moderate-to-severe psoriasis under real-world conditions. Retrospective, observational, open-label, nationwide multicenter cohort study that included patients who initiated treatment with secukinumab in daily clinical practice conditions. PROs assessing disease impact and QoL included Dermatology Life Quality Index (DLQI), Patient's Global Psoriasis Assessment, Itch Numerical Rating Scale and EuroQoL Thermometer Visual Analogue Scale. Outcomes, including PROs and Psoriasis Area and Severity Index (PASI), were assessed at months 3, 6, 12, 18 and 24 during treatment. A total of 238 patients were enrolled in the study. Patients had a mean DLQI score of 14.9 at baseline; 78.3%, 73.7% and 71.7% of them achieved a DLQI 0/1 response at months 6, 12 and 24, respectively. DLQI score was lower in the long term for naïve patients. A sharp decrease in mean DLQI was observed during the first three months, reaching a plateau that was maintained until the end of follow-up. Similar findings were observed for the rest of QoL assessments. There was a close association between improvement in QoL and skin clearance (PASI), which progressively increased during follow-up. In this study, secukinumab sustainably improved patient's QoL during a 24-month follow-up, with strongest effects in patients naïve to biological therapies and with a direct correlation with PASI improvement.

Secukinumab effects on disease burden, patient needs and benefits, and treatment satisfaction in patients with plaque psoriasis across European regions: patient perspective data from the PROSE study

BACKGROUND

Cross-cultural differences in healthcare policies and patient-physician communication may influence the quality of care and patients' perceived benefits and satisfaction with psoriasis treatment.

OBJECTIVES

To compare the disease burden and patient needs at baseline, and patient benefits and satisfaction with secukinumab treatment across Europe.

METHODS

PROSE was an open-label, prospective, non-randomized, stratified multicentre study of 52 weeks of secukinumab treatment, in 16 European countries. Secondary analysis of the PROSE study data by European regions was performed to identify cross-cultural differences in disease burden and patient needs at baseline, and in clinical improvement, patient-reported treatment benefits and satisfaction at 52 weeks post-treatment.

RESULTS

At baseline, Dermatology Life Quality Index impairment was reported to be greater in patients from Eastern Europe (EE: 15.4 ± 7.1) vs. Northern Europe (NE: 13.3 ± 6.7) and Western Europe (WE: 13.6 ± 6.9), but while differences were statistically significant (F-test = 5.5, P < 0.001), their clinical significance is uncertain. There were no significant differences between regions in Psoriasis Area and Severity Index at baseline (F-test = 1.6). There were considerable differences in patients' needs (Patient Need Questionnaire) between geographical regions, with WE focused more on reducing physical impairment [vs. Southern Europe (SE)/EE], EE on reducing social impairment (vs. NE/WE) and SE on reducing impairment due to therapy (vs. NE/WE). At Week 52, patients from EE reported more benefits (Patient Benefit Index) with secukinumab treatment (vs. WE/SE), while patients from NE reported higher global treatment satisfaction (vs. SE).

CONCLUSIONS

Differences in patients' needs and treatment satisfaction across Europe are likely a result of diverse medical systems, socio-economic status and infrastructural access. A patient-centred approach to treating psoriasis may fulfil patient needs and maximize treatment satisfaction. (NCT02752776).

Major Role of the IL17/23 Axis in Psoriasis Supports the Development of New Targeted Therapies

Psoriasis is a frequent, chronic disease characterized by cutaneous inflammatory plaques and/or arthritis. It may be associated with few other diseases, mainly Crohn’s disease and metabolic syndrome. The medical and psychosocial burden of psoriasis remains high even since biological treatments arose, stressing that efforts to decipher its physiopathology are constantly needed. Tumor-necrosis factor α, interleukin (IL) 12 and IL17 have been previously associated with psoriasis and successfully targeted by monoclonal antibodies. IL17 in particular has been initially described as a T helper (Th) 17—produced cytokine, but it is now established that other cell types, such as γδ T lymphocytes, Mucosal-Associated Invariant T (MAIT) cells and Innate Lymphoïd Cells (ILC) 3 are also important sources of IL17 in the skin in response to inflammatory stimuli. Th17 phenotype has been shown to be stabilized by IL23, which is synthetized by macrophages and dendritic cells in response to Toll Like Receptors and C-type Lectin Receptors stimulation. Recent data also reported a crucial role for IL23 in MAIT17 and ILC3 homeostasis. Genome-wide association studies have found a significant link between IL23 receptor polymorphism and psoriasis susceptibility. IL23 signals through Janus kinase 2 and Tyrosine kinase 2, against which specific inhibitors are currently being tested. Monoclonal antibodies against IL17 and IL23 are only the beginning of a new avenue in psoriasis treatment. This review focuses on the molecular basis underlying IL23/IL17 axis blockade in psoriasis, and on future targets in this pathway.

A review of secukinumab in psoriasis treatment

Psoriasis is a systemic immunologic disorder associated with decreased quality of life and numerous co-morbidities, including psoriatic arthritis and cardiovascular disease. Secukinumab, a fully human IgG1 monoclonal antibody, selectively binds IL-17A and is approved by the US FDA and European Medicines Agency for moderate-to-severe plaque psoriasis and psoriatic arthritis. This review examines the efficacy and safety of secukinumab for the treatment of psoriasis using the literature retrieved from the PubMed database. In clinical trials, treatment with secukinumab led to rapid and sustained improvement in Psoriasis Area and Severity Index (PASI) scores, with PASI 90 response rates up to 68.5% at 5 years. Long-term clinical trial and real-world data have established secukinumab as a safe and effective treatment for psoriasis.

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.
