Superior effect of adalimumab versus secukinumab on ultrasound-confirmed synovitis in psoriatic arthritis: comprehensive evidence from musculoskeletal ultrasound and clinical assessments.

Background and objectives: Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disorder affecting 30% of psoriatic patients. Effective treatment, especially with biologics like IL-17 and TNF inhibitors, is vital for improving patient outcomes. This study aimed to compare the efficacy of secukinumab and adalimumab in PsA patients through clinical and ultrasonographic evaluations.Materials and methods: We enrolled 116 PsA patients, with 58 patients receiving secukinumab and 58 receiving adalimumab. Regular follow-ups were conducted at weeks 4, 12, 24, and 52. The primary outcome was the proportion of patients achieving at least a 20% improvement in the ACR response (ACR20) at week 12, with additional evaluations for axial arthritis, enthesitis, skin involvement, minimal disease activity, health assessment questionnaire, and ultrasound changes.Results: There was no significant difference in ACR20 response between the two groups at week 12 (OR: 0.59, 95% CI: 0.26-1.37, p = 0.22). However, secukinumab demonstrated superior efficacy in achieving Psoriasis Area and Severity Index (PASI)90 (OR: 2.25, 95%CI: 1.07-4.74, p = 0.03), while adalimumab showed better improvement in ultrasound synovitis count (ß: 0.94, 95%CI: 0.09-1.79, p = 0.03) and synovitis PD signal (ß: 0.20, 95%CI: 0.03-0.36, p = 0.02).Conclusions: In conclusion, both treatments were highly effective for PsA, with secukinumab being more suitable for severe skin involvement and adalimumab for significant ultrasound-confirmed synovitis.

Four-year effectiveness, safety and drug retention rate of secukinumab in psoriatic arthritis: a real-life Italian multicenter cohort.

OBJECTIVES: to evaluate over a 48-month follow-up period the: 1) long-term effectiveness and safety; 2) drug retention rate (DRR); 3) impact of comorbidities and bDMARDs line on MDA and DAPSA remission/low disease activity (LDA) of secukinumab in a multicenter Italian cohort of PsA patients. METHODS: Consecutive PsA patients receiving secukinumab were followed prospectively in Italian centers between 2016 and 2023. Disease characteristics, previous/ongoing treatments, comorbidities and follow-up duration were recorded. Treatment response was evaluated at 6 and 12 months after initiation, and every year up to 48 months (T48). DRR was assessed according to clinical and demographic features, comorbidities and bDMARDs line. Adverse events (AE) were recorded. RESULTS: Six hundred eighty-five patients [42.5% male] were enrolled; 32.9% naïve received secukinumab; 74.2% had ≥ 1 comorbidity. Overall, secukinumab yielded improved outcomes at T48: naïve maintained lower disease activity vs. non-naïve [DAPSA 4.0 (1.4-8.1) vs. 6.0 (2.2-10.4);p = 0.04]; 76.9% naïve and 66.2% non-naïve achieved MDA; MDA no comorbidities vs. 1-3 comorbidities 78.8% vs. 73.3% (p < 0.05), and MDA no comorbidities vs. > 3 comorbidities 78.8% vs. 48.7% (p < 0.001). DAPSA-REM and DAPSA-LDA rates were higher in naïve patients, albeit similar between those without comorbidities vs. 1-3 comorbidities, and slightly lower in those with > 3 comorbidities. Treatment was discontinued in 233 patients due to loss of effectiveness, and in 41 due to AE. The overall DRR at T48 was 66%, with differences according to bDMARDs line (p < 0.001), use of combined csDMARDs (p = 0.016), BMI (p = 0.037) and mono/oligoarthritis vs. polyarthritis (p = 0.012). CONCLUSIONS: Secukinumab proved safe and effective, and patients achieved sustained remission with a notable drug retention rate at 4 years.

Comparative Efficacy and Safety of Ustekinumab and Secukinumab in the Treatment of Generalized Pustular Psoriasis: A 48-Week Retrospective Cohort Study with Genetic Background Analysis.

Purpose: Recent studies have shown that novel biologics may provide significant clinical benefits for patients with generalized pustular psoriasis (GPP). Ustekinumab and secukinumab have been approved in Japan for GPP treatment in adult patients. However, the differences in efficacy and safety of these two drugs in GPP are not known. Aim: Based on the genetic background, we aimed to compare the efficacy and safety of secukinumab and ustekinumab in patients with GPP. Methods: Patients with moderate to severe GPP who were treated with ustekinumab/secukinumab at our department from July 2019 to May 2022 were included in this study and followed up for 48 weeks. The difference in efficacy between ustekinumab and secukinumab was evaluated by assessing changes in body temperature, laboratory indices, recovery of skin lesions, and changes in quality of life. Additionally, we collected patients' saliva for genotyping and explored the effect of CARD14 genetic mutations on clinical efficacy. Results: A total of 65 patients (32 adults and 33 children) with moderate to severe GPP were included in this study. 31 patients received ustekinumab therapy, and 34 patients were treated with secukinumab. Secukinumab demonstrated superiority to ustekinumab, as evidenced by a higher GPPASI 90 response at week 2. Additionally, the efficacy of ustekinumab and secukinumab was found to be independent of the presence of the CARD14 mutation. Conclusion: Secukinumab is superior to ustekinumab in rapidly clearing the skin and improving health-related quality of life. Moreover, the responses to ustekinumab/secukinumab in patients were not influenced by CARD14 gene mutations.

A Randomized, Double-Blind, Parallel-Group Phase I Study Comparing the Pharmacokinetics, Safety, and Immunogenicity of CMAB015, a Candidate Secukinumab Biosimilar, with Its Reference Product Cosentyx® in Healthy Chinese Male Subjects.

Purpose: Secukinumab, a monoclonal antibody targeting interleukin (IL)-17A, is approved for the treatment of psoriasis, psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, enthesitis-related arthritis, and hidradenitis suppurativa. This study compared the pharmacokinetics (PK), safety, and immunogenicity of CMAB015, a candidate secukinumab biosimilar, with the reference product secukinumab (Cosentyx®) in healthy Chinese male subjects. Patients and methods: This double-blind, parallel-group study randomized healthy Chinese male subjects (N=130) to receive either a single dose of 150 mg CMAB015 or secukinumab subcutaneously. Primary study endpoints were PK parameters such as the maximum concentration (Cmax) and area under the curve from zero to infinity (AUC0-inf), while safety and immunogenicity were secondary endpoints. Results: The 90% confidence intervals (CIs) of the geometric mean ratios (GMRs) of Cmax and AUC0-inf for CMAB015 to secukinumab were all within the bioequivalence limits (80.00-125.00%). Other PK parameters were comparable between the groups. The safety profile of CMAB015 was similar to that of secukinumab, with no serious adverse events related to treatment. The incidence of TEAEs was slightly higher in the CMAB015 group, but these events were mild to moderate in severity and did not lead to any withdrawals from the study. Immunogenicity analysis revealed low rates of anti-drug antibody (ADA) positivity, with similar rates between CMAB015 and secukinumab. Conclusion: This study demonstrated equivalent PK, comparable safety, and immunogenicity of CMAB015 to secukinumab in healthy Chinese male subjects. These findings support further clinical evaluation of CMAB015 as a secukinumab biosimilar. Trial Registration: The trial was registered on Clinicaltrials.gov (Identifier No. NCT05734482) and Chinadrugtrials.org.cn (Identifier No. CTR20230105).

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.

Differential Pharmacodynamic Effects on Psoriatic Biomarkers by Guselkumab Versus Secukinumab Correlate with Long-Term Efficacy: An ECLIPSE Substudy.

IL-23 is a cytokine produced by myeloid cells that drives the T helper 17 pathway and plays an essential role in the pathophysiology of plaque psoriasis. IL-23 activation initiates a cascade of cytokines subsequently inducing the expression of many psoriasis-related proteins. This study aimed to better understand the underlying mechanisms driving the differences between IL-23 and IL-17A blockade in patients with psoriasis and their implications for durability of clinical responses. Serum and/or skin biopsies were isolated from patients treated with guselkumab or secukinumab for evaluation of potential biomarkers of pharmacodynamic response to treatment. Guselkumab treatment led to significantly greater reductions of IL-17F and IL-22 serum levels than treatment with secukinumab at weeks 24 and 48, demonstrating sustained regulation of the IL-23/T helper 17 pathway. Analyses of proteomic and transcriptomic profiles of patient sera and skin biopsies demonstrated differential regulation of proteins involved in chemokine, TNF, and relevant immune signaling pathways to a greater degree with guselkumab than with secukinumab treatment. These data provide insights into the differences between the mechanisms and impact of IL-23 and IL-17A blockade in psoriasis, with implications for efficacy observations and treatment paradigms. Trial Registration: The original study was registered at ClinicalTrials.gov (NCT03090100).

Tofacitinib for Pityriasis Rubra Pilaris: A Case Report.

Purpose: At present, we have entered the era of using biological agents and small molecule targeted drugs to treat diseases. Although there have been many reports of biological agents treating pityriasis rubra pilaris recently, the clinical application of the JAK inhibitors in the treatment of pityriasis rubra pilaris has been rarely reported, and there is a lack of evidence on the safety and efficacy of these drugs. We explore the use of the JAK inhibitor tofacitinib in the treatment of pityriasis rubra pilaris with significant efficacy and no significant side effects, providing new ideas for the clinical treatment of pityriasis rubra pilaris. Methods: We cover a case of pityriasis rubra pilaris treated with the JAK inhibitor tofacitinib, which showed significant efficacy without any adverse effects. Results: This case report showed that the JAK inhibitor tofacitinib had significant clinical efficacy in the treatment of pityriasis rubra pilaris. We speculated that the treatment of pityriasis rubra pilaris with the JAK inhibitors may be related to blocking the activation of the JAK/STAT pathway, thereby blocking the high expression of cytokines IL-17, IL-12/IL-23, IL-23, TNF-α. Conclusion: The JAK inhibitor tofacitinib can become a new option for treating pityriasis rubra pilaris.

Biologic anti-IL17 drugs in erythrodermic psoriasis.

Background: Erythrodermic psoriasis (EP) is a potentially life-threatening disease, and there is currently no consensus regarding its optimal treatment. Biological drugs approved for Psoriasis Vulgaris treatment have been used as alternatives to traditional medications. Objective: To evaluate the clinical response and tolerability of anti- interleukin 17 (IL17) biologic drugs during a 2-year-follow-up. Methods: This was a retrospective prospective study. EP cases, defined as >75% body surface area involvement, in patients ≥18 years old treated with anti-IL17 for at least 6 consecutive months were enrolled and then followed until 104 weeks. Patient characteristics, overall clinical responses, Psoriasis Area Severity Index score changes, and adverse events were analyzed. Results: Sixteen patients met the criteria, of which 50% had achieved the Psoriasis Area Severity Index 100 response at week 12 and in 93.7% at week 24. In the prospective observation of the cohort, 87.5% were still in remission at week 52 and 81.25% at 104 weeks, without adverse events. The 3 patients in whom the treatment was interrupted lost efficacy and were switched to other therapies. Limitations: Only descriptive analysis was conducted due to the limited number of patients. Conclusions: A satisfactory long-term clinical response without adverse effects was observed in this case series, suggesting the interest of anti-IL17 in EP treatment.

Management of Drug-Induced Psoriasis With Secukinumab in a Patient With Schizoaffective Disorder: A Case Report.

Psoriasis is a chronic inflammatory systemic disorder often associated with psychiatric comorbidities such as depression and anxiety. This case report describes a 25-year-old man with schizoaffective disorder, bipolar type, whose suicidal ideation was worsened by a severe psoriasis flare that was induced by the initiation of lithium for psychiatric management. Lithium was switched to valproate, and treatment with secukinumab, an IL-17A inhibitor, was initiated, resulting in significant improvement in both psoriasis and mental health. This case highlights the phenomenon of drug-induced psoriasis, emphasizing the need for a high index of suspicion and careful review of past medical history. It underscores the reciprocal relationship between psoriasis and psychiatric comorbidities, advocating for a tailored approach to treating both conditions to achieve optimal outcomes.

Clinical efficacy and safety of secukinumab in the treatment of generalized pustular psoriasis in the pediatric population: a systematic review of the literature.

Background: Generalized pustular psoriasis (GPP) is a severe type of psoriasis. The current treatment primarily relies on corticosteroids and immunosuppressants. In recent years, biologics have been increasingly utilized in the treatment of this disease, and have demonstrated good clinical efficacy. However, children and adolescents are primarily treated with immunosuppressants, which have limited clinical application due to the serious side effects they may cause. At the same time, the effectiveness of current treatments is unsatisfactory. Secukinumab has been widely reported to be effective and safe in treating this disease. However, there are still insufficient data on its use in treating GPP in children. Objective: To conduct a systematic review of the existing literature on the use of secukinumab for treating generalized pustular psoriasis in children and adolescents, and to evaluate its clinical effectiveness and safety. Methods: We conducted a systematic review of all the literature reporting on the treatment of GPP in children and adolescents with secukinumab. Results: A total of 7 papers (46 patients) were included in this study. After 12 weeks of treatment, all 46 participants were able to achieve a GPPASI score of 90 or higher, with approximately 96% of patients achieving complete clearing of the lesions (GPPASI 100 or JDA0). Adverse events were reported in 8 patients, the rate of adverse reactions was approximately 17%. Conclusion: The treatment of GPP in children and adolescents with secukinumab has a rapid onset of action and a high safety profile. However, the results of the literature may be influenced by publication bias.

Analysis of the shorter drug survival times for Janus kinase inhibitors and interleukin-17 inhibitors compared with tumor necrosis factor inhibitors in a real-world cohort of axial spondyloarthritis patients - a retrospective analysis from the RHADAR network.

In recent years Janus kinase inhibitors (JAKi) have joined tumor necrosis factor inhibitors (TNFi) and interleukin (IL)-17 inhibitors (IL-17i) as approved disease modifying anti-rheumatic drugs (DMARD) for moderate to severe forms of axial spondyloarthritis (axSpA). Drug survival in axSpA patients has not been well studied in a real-world outpatient scenario since the approval of JAKi. We aimed to analyze the three drug classes based on modes of actions (MoA) for their persistence rates among German axSpA outpatients. A retrospective analysis of the RHADAR database for axSpA patients with a new initiation of TNFi, IL-17i, or JAKi treatment between January 2015 and October 2023 was conducted. Analyses included Kaplan-Meier curves and adjusted Cox regressions for drug discontinuation. 1222 new biological DMARD (TNFi [n = 954], IL-17i [n = 190]) or JAKi (n = 78) treatments were reported. The median drug survival was 31 months for TNFi, 25 for IL-17i, and 18 for JAKi. The corresponding 2-year drug survival rate was 79.6%, 72.6%, and 62.8% for TNFi, IL-17i, and JAKi, respectively. The probability for discontinuation for JAKi was significantly higher compared with TNFi (HR 1.91 [95% CI 1.22-2.99]) as well as for IL-17i compared with TNFi (HR 1.43 [95% CI 1.02-2.01]), possibly related to more frequent use of TNFis as first-line therapy. IL-17i and JAKi discontinuation probabilities were similar. Primary non-response was the reason for drug discontinuation in most cases across all MoA. TNFi treatment might persist longer than JAKi and IL-17i in German axSpA outpatients, possibly related to more severe or refractory disease in patients with JAKi-treated or IL-17i-treated axSpA.

Secukinumab Ameliorates Oxidative Damage Induced by Subarachnoid Hemorrhage.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: This study revealed that SEC (3 mg/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.

A secukinumab dose-escalation study in patients with ankylosing spondylitis not achieving inactive disease after 16 weeks of treatment.

OBJECTIVE: To investigate the clinical response at week 52 in patients with ankylosing spondylitis (AS) who received secukinumab 300 vs 150 mg after inadequate response to 150 mg at week 16. METHODS: ASLeap (NCT03350815) was a randomized, double-blind, parallel-group, multicentre, phase 4 trial. After 16 weeks of open-label secukinumab 150 mg (Treatment Period 1), patients who did not achieve inactive disease (Ankylosing Spondylitis Disease Activity Score [ASDAS] <1.3) at both Weeks 12 and 16 were considered to have an inadequate response and were randomized 1:1 to receive secukinumab 300 or 150 mg every 4 weeks until week 52 (Treatment Period 2). The primary efficacy variable was achievement of ASDAS <1.3 at week 52 using week 16 as baseline. Safety was evaluated by the incidence of treatment-emergent adverse events through week 52. RESULTS: Of 322 patients treated with secukinumab in Treatment Period 1, 207 (64.3%) had inadequate response. Similar proportions of patients with inadequate response randomized to secukinumab 300 mg (n = 101) and 150 mg (n = 105) in Treatment Period 2 completed the study (83.8% and 84.3%, respectively). At week 52, 8.8% and 6.7% of patients receiving secukinumab 300 and 150 mg, respectively, achieved ASDAS <1.3. The incidence of treatment-emergent adverse events was similar in both groups through week 52. No new safety signals were observed. CONCLUSION: Patients with AS who did not achieve ASDAS <1.3 after receiving secukinumab 150 mg for 16 weeks experienced similar clinical response and safety through week 52 regardless of dose escalation. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03350815.
