Abstract
Subcutaneous delivery of monoclonal antibody therapeutics is often preferred to intravenous delivery due to better patient compliance and overall lower cost to the healthcare system. However, the systemic absorption of biologics dosed subcutaneously is often incomplete. The aim of this work was to describe a human bioavailability prediction method for monoclonal antibodies delivered subcutaneously that utilizes intravenous pharmacokinetic parameters as input. A two-compartment pharmacokinetic model featuring a parallel-competitive absorption pathway and a presystemic metabolism pathway was employed. A training data set comprised 19 monoclonal antibodies (geometric mean bioavailability of 68%), with previously reported human pharmacokinetic parameters, while a validation set included data compiled from 5 commercial drug products (geometric mean bioavailability of 69%). A single fitted absorption rate constant, paired with compound-specific estimates of presystemic metabolism rate proportional to compound-specific systemic clearance parameters, resulted in calculations of human subcutaneous bioavailability closely mimicking clinical data in the training data set with a root-mean-square error of 5.5%. Application of the same approach to the validation data set resulted in predictions characterized by 12.6% root-mean-square error. Factors that may have impacted the prediction accuracy include a limited number of validation data set compounds and an uncertainty in the absorption rate, which were subsequently discussed. The predictive method described herein provides an initial estimate of the subcutaneous bioavailability based exclusively on pharmacokinetic parameters available from intravenous dosing.

Abstract
PURPOSE To demonstrate the effective integration of pharmacometrics and pharmacovigilance in managing medication errors, highlighted by a case involving secukinumab in a patient with hidradenitis suppurativa. METHODS We present the case of a 41-year-old male with progressive hidradenitis suppurativa, unresponsive to multiple antibiotic regimens and infliximab treatment. Due to a medication error, the patient received 300 mg of secukinumab daily for 4 days instead of weekly, totaling 1200 mg. The regional pharmacovigilance center assessed potential toxicity, and a pharmacometric analysis using a population pharmacokinetic model was performed to inform dosing adjustments. RESULTS Clinical data indicated that the received doses were within a non-toxic range. No adverse effects were observed. Pharmacometric simulations revealed a risk of underexposure due to the dosing error. Based on these simulations, it was recommended to restart monthly secukinumab injections on day 35 after the initial dose. Measured plasma concentrations before re-administration confirmed the model's accuracy. CONCLUSION This case highlights the crucial collaboration between clinical services, pharmacovigilance, and pharmacometrics in managing medication errors. Such interdisciplinary efforts ensure therapeutic efficacy and patient safety by maintaining appropriate drug exposure levels.

Abstract
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).

Abstract
OBJECTIVES Interleukin-17 (IL-17) contributes to the pathogenesis of psoriasis. Secukinumab, ixekizumab, and brodalumab are monoclonal antibodies anti-IL-17 antibodies, approved for the treatment of moderate/severe plaque psoriasis.The aim of the study was to describe the effectiveness and safety of anti-IL-17 agents in moderate/severe plaque psoriasis in clinical practice. We also analysed anti-IL-17 therapies' survival, dose adjustment, and clinical patients' factors associated with their effectiveness and safety. METHODS A retrospective, longitudinal study was conducted at a tertiary hospital. We included patients with moderate/severe psoriasis treated with anti-IL-17 agents. The effectiveness was evaluated with Psoriasis Area and Severity Index (PASI) score and safety through the adverse drug reactions (ADRs) collected. RESULTS 38 patients were studied (median age=47.4 years, 71.0% male). The mean number of biological therapies that patients received was 2.6, and anti-IL-17 therapy was the first biological therapy for 36.8% of patients. The median years in treatment were 2.5 (95% CI 1.95 to 2.98) for secukinumab, 1.2 (95% CI 0.36 to 1.47) for ixekizumab, and 0.7 (IQR 0.71) for brodalumab. The median PASI score after 6 months of treatment was 0 (IQR 0) and 85.3% of patients achieved a PASI of 90 (84.0% with secukinumab, 87.5% with ixekizumab, and 100% with brodalumab). Dose adjustment was associated with the line of treatment (p=0.034 for naïve patients), age (p=0.044 for younger patients), and concomitant pathologies (p=0.015 without more diseases).24 patients suffered from ADRs, mainly infections of the upper respiratory tract, and there were no statistically significant differences between the three therapies. CONCLUSIONS Anti-IL-17 agents constitute an effective treatment for patients with moderate/severe plaque psoriasis and for longer. Dose reductions were associated with fewer lines of treatment, younger patients and absence of concomitant pathologies. ADR were minor and similar among the anti-IL-17.

Abstract
INTRODUCTION Interleukin-17A (IL-17A) plays a crucial role in the pathogenesis of ankylosing spondylitis (AS), although not all patients respond to traditional IL-17A antibody treatments. QX002N injection, as a new monoclonal antibody targeting IL-17A, has shown potential in treating AS, offering a new treatment option for patients who do not respond well to existing therapies. METHODS A randomized, open, parallel, single-center, phase I study was conducted to assess the pharmacokinetics, safety, and immunogenicity of single doses of QX002N injection administered intravenously (IV) or subcutaneously (SC) to healthy Chinese volunteers. Blood samples were collected at specified time intervals, and then serum concentrations of QX002N were analyzed by enzyme-linked immunosorbent assay. RESULTS Pharmacokinetic analysis of the drug concentration-time data showed that the mean maximum observed serum QX002N concentration (Cmax) was 110 and 33.9 µg/ml, respectively. The average area under the drug concentration-time curves from 0 to the time of the last quantifiable concentration (AUClast) were 52,656 and 36,269 µg·h/ml, respectively and the average area under the drug concentration-time curves from 0 to infinity (AUCinf) were 54,867 and 38,194 µg·h/ml, respectively. The absolute bioavailability of QX002N after SC injection was 69.6%. CONCLUSIONS Immunogenicity was assessed and all the subjects in this study were Anti-drug antibody (ADA)-negative, which means no subjects appeared to develop immunogenicity to QX002N. All the results testify to the safety of QX002N injection, which is satisfactory after IV or SC dosing in healthy subjects. TRIAL REGISTRATION www.chinadrugtirals.org.cn , CTR20220430.

Abstract
BACKGROUND Secukinumab is effective against a range of psoriatic manifestations. Investigating psoriasis (PsO) relapse following secukinumab discontinuation could provide insights into long-term PsO remission. OBJECTIVES To examine PsO relapse rates on treatment discontinuation following 1 year of secukinumab treatment. METHODS This study (clinical trial number: NCT01544595) is an extension of the phase III ERASURE/FIXTURE studies in patients with moderate-to-severe plaque PsO. After 1 year of secukinumab 300 mg or 150 mg treatment, participants who had responded to treatment with a ≥ 75% reduction in Psoriasis Area and Severity Index (PASI 75) at week 52 were randomly assigned to receive placebo (n = 120 and n = 100, respectively). On relapse, patients receiving placebo were switched to their previous secukinumab dose. The study primary outcome was the nonrelapse rate after secukinumab withdrawal. RESULTS Following the last dose of secukinumab 300 mg, 20.8% (25/120) and 10.0% (12/120) of patients who switched to placebo did not relapse at 1 and 2 years after discontinuation, respectively. Patients who received secukinumab 150 mg for 1 year showed a lower proportion of nonrelapse following treatment discontinuation [14% (14/100) and 6% (6/100)] at 1 and 2 years, respectively. Patients who did not relapse maintained low mean PASI (2.8) at 1 year drug free vs. baseline (20.9); 1.7 at 2 years drug free vs. baseline (19.2), following an initial 52-week treatment with secukinumab 300 mg. Disease duration (P = 0.02) and severity (P = 0.02) were significantly associated with time to relapse in patients initially treated with secukinumab 300 mg; patients with shorter disease duration and lower baseline PASI remained relapse-free for longer. CONCLUSIONS Following discontinuation of secukinumab, a proportion of patients stayed relapse-free. Further, patients with shorter disease duration remained relapse-free for longer, suggesting that earlier treatment with secukinumab may result in long-term clinical control of moderate-to-severe PsO.

Abstract
INTRODUCTION The aim of this work is to evaluate secukinumab vs. placebo in a challenging-to-treat and smaller US patient subpopulation of the international FUTURE 2-5 studies in patients with psoriatic arthritis (PsA). METHODS Data were pooled from US patients enrolled in the phase 3 FUTURE 2-5 studies (NCT01752634, NCT01989468, NCT02294227, and NCT02404350). Patients received secukinumab 300 or 150 mg with subcutaneous loading dose, secukinumab 150 mg without subcutaneous loading dose, or placebo. Categorical efficacy and health-related quality-of-life (QoL) outcomes and safety were evaluated at week 16. Subgroup analyses were performed based on tumor necrosis factor inhibitor (TNFi) status and body mass index (BMI). For hypothesis generation, odds ratios (ORs) for American College of Rheumatology (ACR) 20/50/70 and Psoriasis Area and Severity Index (PASI) 75/90/100 responses by treatment were estimated using logistic regression without adjustment for multiple comparisons. RESULTS Of 2148 international patients originally randomized, 279 US patients were included in this pooled analysis. Mean BMI was > 30 kg/m2 and 55.2% had prior TNFi treatment. ORs for ACR20/50/70 significantly favored patients receiving secukinumab 300 mg and 150 mg with loading dose vs. placebo (P < 0.05), but not those receiving secukinumab 150 mg without loading dose vs. placebo. For PASI75, ORs favored all secukinumab groups over placebo (P < 0.05); for PASI90 and PASI100, only the secukinumab 300-mg group was significantly favored over placebo (P < 0.05). CONCLUSIONS In this challenging sub-population of US patients with PsA, secukinumab provided rapid improvements in disease activity and QoL. Patients with PsA and active psoriasis might benefit more from secukinumab 300 mg than 150 mg.

Abstract
INTRODUCTION Until recently, biological therapy for hidradenitis suppurativa was limited to anti-tumor necrosis factor (TNF) blockade with adalimumab (ADA). However, not all patients respond to treatment with ADA. This highlighted the need for more therapeutic options. Interleukin (IL)-17/T-helper 17 (Th17) axis may play an important role in the pathophysiology of HS. Recently, the IL-17A inhibitor secukinumab, which targets IL-17A specifically and prevents it from interacting with the IL-17 receptor, has been FDA-approved for HS. AREAS COVERED Secukinumab, represents a novel therapeutic strategy in HS management. An overview of structural and pharmacological characteristics is provided. Described efficacy in clinical trials and case reports and safety data from is presented. EXPERT OPINION As response to anti-TNFas is lost over time, secukinumab has provided an alternative HS treatment option in clinical practice. Overall, secukinumab has shown good efficacy and a favorable side effect profile in HS clinical trials but may be avoided in patients with inflammatory bowel disease. Long-term and real-life data on the use of secukinumab are essential for improving decision-making in HS therapy.

Abstract
Psoriasis is a common inflammatory immune disorder due to chronic activation of the adaptive and innate immune responses. Therapies for psoriasis target reducing inflammatory cytokines such as tumor necrosis factor-alpha, interleukin-17, and interleukin-22. Patients with inflammatory disorders have reduced metabolism by cytochrome P450 enzymes in the liver. The pharmacokinetic and pharmacodynamic changes due to psoriasis also have an impact on reaching therapeutic concentrations of the drug. Pharmacokinetic and pharmacodynamic data help determine the safety and clinical considerations necessary when utilizing drugs for plaque psoriasis. A literature search was performed on PubMed and Ovid MEDLINE for the pharmacokinetic and pharmacodynamic data of oral therapies and biologics utilized for moderate-to-severe plaque psoriasis. The findings from the literature search were organized into two sections: oral therapies and biologics. The pharmacokinetic and pharmacodynamic parameters in healthy patients, patients with psoriasis, and special populations are discussed in each section. The oral therapies described in this review include methotrexate, cyclosporine, apremilast, tofacitinib, and deucravacitinib. Biologics include tumor necrosis factor-alpha inhibitors, interleukin-17 inhibitors, ustekinumab, and interleukin-23 inhibitors. Clinical considerations for these therapies include drug toxicities, dosing frequency, and anti-drug antibodies. Methotrexate and cyclosporine have a risk for hepatoxicity and renal impairment, respectively. Moreover, drugs metabolized via cytochrome P450, including tofacitinib and apremilast have decreased clearance in patients with psoriasis, requiring dose adjustments. Patients treated with therapies such as adalimumab can develop anti-drug antibodies that reduce the long-term efficacy of the drug. Additionally, overweight patients benefit from more frequent dosing to achieve better psoriasis clearance.

There is still scope for the development of affordable treatments for PsO. OBJECTIVES To assess, in a phase Ia study, the safety, tolerability and pharmacokinetics (PK) of HB0017, a humanized monoclonal antibody that targets IL-17A, in healthy participants and patients with moderate-to-severe plaque PsO; and, in a phase Ib study, to assess the efficacy of HB0017 in patients with moderate-to-severe plaque PsO. METHODS The phase Ia study (NCT04505033) was a randomized double-blind placebo-controlled dose-escalation study in healthy participants. Each cohort of 10 volunteers was randomly assigned to receive either a single dose of HB0017 (50 mg, 150 mg, 300 mg or 450 mg) or the matching placebo at a ratio of 4 : 1. The phase Ib study (NCT05442788) was a randomized double-blind placebo-controlled dose-escalation study in enrolled patients with moderate-to-severe plaque PsO. Each cohort of 10 patients was randomly assigned to receive either multiple doses of HB0017 (150 mg, 300 mg or 450 mg) or the matching placebo at a ratio of 4 : 1. RESULTS HB0017 demonstrated dose-proportional linear PK and was tolerated across the dose range assessed. In the phase Ia and Ib studies, participants in both the HB0017 and placebo groups experienced treatment-emergent adverse events (69% vs. 87%, 96% vs. 100%, respectively). HB0017 demonstrated clinically meaningful effects in patients with moderate-to-severe plaque PsO. PASI 75 [≥ 75% improvement in Psoriasis Area and Severity Index (PASI)], PASI 90 (≥ 90% improvement in PASI) and static Physician Global Assessment (sPGA) 0/1 (i.e. 'clear' or 'almost clear') responses were 100% for the HB0017 300-mg group, with maximal improvements (100% or near 100% reductions from baseline) in PASI score observed at week 12, while the duration of effect was evident up to week 20. There was no clinical response in any participant in the placebo group in the phase Ib study. CONCLUSIONS Overall, HB0017 showed acceptable safety and tolerability in both healthy participants and patients with moderate-to-severe plaque PsO. An encouraging signal of efficacy with a longer half-life provides HB0017 with the potential to be added to the currently available range of biologics targeting IL-17A.

Abstract
The IL-17 pathways are involved in the pathophysiology of many inflammatory skin conditions, including hidradenitis suppurativa. Secukinumab, an IL-17A inhibitor, has been used for years in inflammatory skin disorders such as psoriasis. To date, the only US FDA-approved medication for hidradenitis suppurativa is adalimumab, a TNF-α inhibitor. Recently, secukinumab has demonstrated promising results in the treatment of hidradenitis suppurativa in the phase III SUNSHINE and SUNRISE clinical trials. This article reviews the mechanism of action of secukinumab and summarizes the available clinical efficacy and safety data regarding secukinumab in the management of hidradenitis suppurativa.

Abstract
BACKGROUND Few studies have explored the immunology and genetic risk of paradoxical eczema occurring as an adverse event of biologic therapy in patients with psoriasis. OBJECTIVES We sought to describe the systemic inflammatory signature of paradoxical eczema using proteomics and explore whether this is genetically mediated. METHODS This study used the Olink Target 96 Inflammation panel on 256 serum samples from 71 patients with psoriasis and paradoxical eczema, and 75 controls with psoriasis to identify differentially expressed proteins and enriched gene sets. Case samples from 1 or more time points (T1 prebiologic, T2 postbiologic, and T3 postparadoxical eczema) were matched 1:1 with control samples. Genes contributing to enriched gene sets were selected, and functional single nucleotide polymorphisms used to create polygenic risk scores in a genotyped cohort of 88 paradoxical eczema cases and 3124 psoriasis controls. RESULTS STAMBP expression was lower in cases at T1 than in controls (log-fold change: -0.44; adjusted P = .022); no other proteins reached statistical significance at equivalent time points. Eleven gene sets including cytokine and chemokine pathways were enriched in cases at T2 and 10 at T3. Of the 39 proteins contributing to enriched gene sets, the majority are associated with the atopic dermatitis serum proteome. A polygenic risk score including 38 functional single nucleotide polymorphisms linked to enriched gene sets was associated with paradoxical eczema (adjusted P = .046). CONCLUSIONS The paradoxical eczema systemic inflammatory proteome trends toward atopic dermatitis at a gene-set level and is detectable before onset of the phenotype. This signature could be genetically determined.

Abstract
BACKGROUND Further dose optimization is required for patients with moderate-to-severe plaque psoriasis who do not benefit from the approved secukinumab dose regimen. This study aimed to develop an exposure-response model for secukinumab to recommend dose regimens for patients of different body weights. METHODS We searched the PubMed and Cochrane Library databases for randomized controlled trials using PASI 75 and PASI 90 response rates as primary outcomes. A model-based meta-analysis was developed to quantitatively analyze the distribution of six secukinumab dose regimens in patients weighing 50-120 kg. RESULTS Sixteen trials involving 6,197 subjects were included in the analysis. The established model accurately described the time-course characteristics of PASI 75 and PASI 90 response rates over 52 weeks. Simulations indicated that maintenance doses could be reduced to 150 mg every 4 weeks and to 150 mg every 3 weeks for patients weighing 50 and 60 kg, respectively. In contrast, maintenance doses of 300 mg every 3 weeks should be selected for patients weighing 120 kg. Patients weighing 70-110 kg remained on approved maintenance doses of 300 mg every 4 weeks. CONCLUSIONS Based on patient body weights, the exposure-response model recommends efficacious and economical dose regimens for patients with moderate-to-severe plaque psoriasis.

Abstract
Dysregulation of the alternative complement pathway predisposes individuals to a number of diseases. It can either be evoked by genetic alterations in or by stabilizing antibodies to important pathway components and typically leads to severe diseases such as paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, C3 glomerulopathy, and age-related macular degeneration. In addition, the alternative pathway may also be involved in many other diseases where its amplifying function for all complement pathways might play a role. To identify specific alternative pathway inhibitors that qualify as therapeutics for these diseases, drug discovery efforts have focused on the two central proteases of the pathway, factor B and factor D. Although drug discovery has been challenging for a number of reasons, potent and selective low-molecular weight (LMW) oral inhibitors have now been discovered for both proteases and several molecules are in clinical development for multiple complement-mediated diseases. While the clinical development of these inhibitors initially focuses on diseases with systemic and/or peripheral tissue complement activation, the availability of LMW inhibitors may also open up the prospect of inhibiting complement in the central nervous system where its activation may also play an important role in several neurodegenerative diseases.

Utility of in silico prediction of target suppression for antibodies against soluble targets: static versus dynamic models. Eur J Clin Pharmacol 2023; 79:137-147.

Abstract
PURPOSE Antibodies that bind soluble targets such as cytokines belong to an important class of immunotherapies. Target levels can significantly accumulate after antibody administration due to formation of antibody-target complex, accompanied with suppression in free target which is often difficult to measure. Being a surrogate for pharmacodynamic activity, free target suppression is often predicted using in silico tools. The objective of this work is to illustrate the utility of modelling and to compare static versus dynamic models in the prediction of free target suppression. METHODS Using binding principles, we have derived a static equation to predict free target suppression at steady state (FTSS). This equation operates with five input parameters and accounts for target accumulation over time. Its predictivity was compared to a dynamic model and to other existing metrics in literature via simulations and assumptions were illustrated. RESULTS We demonstrated the utility of in silico tools in prediction of free target suppression using static and dynamic models and clarified the assumptions in key input parameters and their limitations. Predicted values using the FTSS equation correlate very well with those from the dynamic model at level > 20% target suppression, relevant for antagonistic antibodies. CONCLUSION In silico tools are needed to predict target suppression by antibody drugs. Static or dynamic models can be used dependant on the scope, available data and undertaken assumptions. These tools can be used to guide discovery and development of antibodies and has the potential to reduce clinical failure.

Abstract
The endocannabinoid system has been shown to be involved in various skin functions, such as melanogenesis and the maintenance of redox balance in skin cells exposed to UV radiation, as well as barrier functions, sebaceous gland activity, wound healing and the skin's immune response. In addition to the potential use of cannabinoids in the treatment and prevention of skin cancer, cannabinoid compounds and derivatives are of interest as potential systemic and topical applications for the treatment of various inflammatory, fibrotic and pruritic skin conditions. In this context, cannabinoid compounds have been successfully tested as a therapeutic option for the treatment of androgenetic alopecia, atopic and seborrhoeic dermatitis, dermatomyositis, asteatotic and atopic eczema, uraemic pruritis, scalp psoriasis, systemic sclerosis and venous leg ulcers. This review provides an insight into the current literature on cannabinoid compounds as potential medicines for the treatment of skin diseases.

Abstract
Abstract
Background
Generalized pustular psoriasis (GPP) usually presents with fever, generalized flushing, and multiple sterile pustules on the skin, which histopathologically form subcorneal pustules characterized by Kogoj spongiform pustules. Granulocyte/monocyte adsorption apheresis (GMA) was approved in Japan in 2012. The use of biologics for psoriasis treatment is increasing. Several case reports have evaluated the combination of GMA and cyclosporine (CyA) for GPP. However, very few English reports on combining biologics and GMA in treating GPP exist.
Case presentation
A 79-year-old man with a history of hypertension, diabetes mellitus, chronic kidney disease, and atrial fibrillation was admitted. He had been consulting a dermatologist for psoriasis vulgaris (PV) since the age of 44. The patient was diagnosed with severe GPP and treated with 300 mg secukinumab (SEC) on day 3. SEC is a fully human monoclonal IgG1 antibody that targets IL-17A. Five doses were administered. In addition, GMA was administered once a week, three times from day 4. After the first administration of GMA, the inflammatory response and skin condition improved markedly. The patient was discharged from the hospital on day 34.
Conclusions
The present study is the first English-written report on the combined administration of SEC and GMA both instituted since admission for severe GPP, with immediate patient response to treatment. Notably, IL-17A plays a vital role in the pathogenesis of GPP. GMA can eliminate activated leukocytes, and the early introduction of combined IL-17 monoclonal antibody and GMA may allow disease suppression in patients with severe GPP, thus avoiding progression to multiorgan failure. Further studies may verify the effects of IL-17 monoclonal antibodies and GMA on severe GPP.

Population pharmacokinetic/pharmacodynamic analysis of AK111, an IL-17A monoclonal antibody, in subjects with moderate-to-severe plaque psoriasis. Front Pharmacol 2022; 13:966176.

Abstract
AK111 is an innovative IL-17A antibody, presenting high affinity to IL-17A and showing similar pharmacokinetic (PK) characteristics to those of typical immunoglobulin (Ig) G1 antibodies. To optimize the dosage regimen for phase 2/3 clinical trials, PK and pharmacodynamics (PD) of AK111 were first characterized in Chinese moderate-to-severe plaque psoriasis patients in a phase 1b study. AK111 PK serum sample and Psoriasis Area and Severity Index (PASI) score data were collected from 48 moderate-to-severe psoriasis patients in this study. Non-linear mixed-effects modeling was used for the population PK/PD analysis. A one-compartment model with a first-order absorption and a first-order elimination best described the PK behavior of AK111. The apparent systemic clearance was 0.182 L/day, and the central volume was 6.65 L. The exposure–response relationship was characterized using an indirect response model. The pharmacological effect of AK111 was described in the form of inhibiting the formation of psoriatic plaque, whereas placebo was quantified in the form of promoting the degradation of psoriatic skin lesions. The maximum effect of drug effect (Imax) and placebo effect (PLBmax) was 1 and 0.429, respectively. The rate constant for psoriatic plaque production (Kin) was 0.474 PASI/day and psoriatic plaque loss (Kout) was 0.024 day−1. The body surface area (BSA) affected by psoriasis was identified as a significant covariate on Kout. The simulation results confirmed that all of the predicted PASI90 response rates at week 12 were higher than 60% at 150 and 300 mg dose levels with different regimens and could reach higher than 80% at week 24. We hope this first PK/PD study of AK111 in Chinese moderate-to-severe plaque psoriasis patients will be of help in the further clinical development of AK111 and provide a reference to the dosage optimization for similar antibodies with a long half-life.

Abstract
The pharmacologic effect(s) of biotherapeutics directed against soluble targets are driven by the magnitude and duration of free target suppression at the tissue site(s) of action. Interleukin (IL)-17A is an inflammatory cytokine that plays a key role in the pathogenesis of psoriasis. In this work, clinical trial data from two monoclonal antibodies (mAbs) targeting IL-17A for treatment of psoriasis (secukinumab and ixekizumab) were analyzed simultaneously to quantitatively predict their target engagement (TE) profiles in psoriatic skin. First, a model-based meta-analysis (MBMA) for clinical responses was conducted separately for each drug based on dose. Next, a minimal physiologically-based pharmacokinetic (mPBPK) model was built to assess skin site IL-17A target engagement for ixekizumab and secukinumab simultaneously. The mPBPK model captured the observed drug PK, serum total IL-17A, and skin drug concentration-time profiles reasonably well across the different dosage regimens investigated. The developed mPBPK model was then used to predict the average TE (i.e., free IL-17A suppression) in skin achieved over a 12-weeks treatment period for each drug following their respective regimens and subsequently assess the TE-efficacy response relationship. It was predicted that secukinumab achieved 98.6% average TE in the skin at 300 mg q4w SC while ixekizumab achieved 99.9% average TE under 160 mg (loading) followed by 80 mg q2w SC. While direct quantification of free IL-17A levels at the site of action is technically challenging, integrated mPBPK-MBMA approaches offer quantitative predictions of free IL-17A levels at the site of action to facilitate future drug development via IL-17A suppression in psoriasis.

Abstract
Objective To evaluate secukinumab 300 mg and 150 mg vs placebo in a US-only population of biologic-naive patients with psoriatic arthritis (PsA). Methods CHOICE was a randomized, double-blind, controlled trial conducted in the United States. Biologic-naive patients with PsA and psoriasis were randomized 2:2:1 to secukinumab 300 mg (n = 103), secukinumab 150 mg (n = 103), or placebo (n = 52). The primary objective was to show superiority of secukinumab 300 mg vs placebo in ACR20 response at week 16. Additional objectives included the effect of secukinumab on dactylitis, enthesitis, psoriasis, and safety. Results ACR20 response rates at week 16 were higher with secukinumab 300 mg than with placebo (51.5% vs 23.1%; odds ratio, 3.51 [95% CI: 1.65, 7.45]; P = .0011). Secukinumab 300 mg also led to greater ACR50/70 responses and improvements in other variables vs placebo. Responses were generally sustained over time. Patients with inadequate response to secukinumab 150 mg at weeks 16, 28, or 40 who received dose escalation to 300 mg experienced improved clinical response after uptitration. The most common adverse events were upper respiratory tract infections and diarrhea. No inflammatory bowel disease was reported or new safety signals observed. Conclusion Secukinumab 300 mg led to rapid and significant improvements over placebo in symptoms of PsA in this heavier population of US-only biologic-naive patients. Findings were consistent with previous studies and suggest that secukinumab 300 mg is a safe and efficacious first-line biologic treatment for patients with PsA.

Abstract
PURPOSE Dysregulations of key signaling pathways in metabolic syndrome are multifactorial, eventually leading to cardiovascular events. Hyperglycemia in conjunction with dyslipidemia induces insulin resistance and provokes release of proinflammatory cytokines resulting in chronic inflammation, accelerated lipid peroxidation with further development of atherosclerotic alterations and diabetes. We have proposed a novel combinatorial approach using FDA approved compounds targeting IL-17a and DPP4 to ameliorate a significant portion of the clustered clinical risks in patients with metabolic syndrome. In our current research we have modeled the outcomes of metabolic syndrome treatment using two distinct drug classes. METHODS Targets were chosen based on the clustered clinical risks in metabolic syndrome: dyslipidemia, insulin resistance, impaired glucose control, and chronic inflammation. Drug development platform, BIOiSIM™, was used to narrow down two different drug classes with distinct modes of action and modalities. Pharmacokinetic and pharmacodynamic profiles of the most promising drugs were modeling showing predicted outcomes of combinatorial therapeutic interventions. RESULTS Preliminary studies demonstrated that the most promising drugs belong to DPP-4 inhibitors and IL-17A inhibitors. Evogliptin was chosen to be a candidate for regulating glucose control with long term collateral benefit of weight loss and improved lipid profiles. Secukinumab, an IL-17A sequestering agent used in treating psoriasis, was selected as a repurposed candidate to address the sequential inflammatory disorders that follow the first metabolic insult. CONCLUSIONS Our analysis suggests this novel combinatorial therapeutic approach inducing DPP4 and Il-17a suppression has a high likelihood of ameliorating a significant portion of the clustered clinical risk in metabolic syndrome.

Impact of Pharmacokinetic and Pharmacodynamic Properties of Monoclonal Antibodies in the Management of Psoriasis. Pharmaceutics 2022; 14:pharmaceutics14030654. [PMID: 35336028 PMCID: PMC8954607 DOI: 10.3390/pharmaceutics14030654] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 02/24/2022] [Accepted: 03/11/2022] [Indexed: 12/14/2022] Open
Abstract
The treatment of psoriasis has been revolutionized by the emergence of biological therapies. Monoclonal antibodies (mAb) generally have complex pharmacokinetic (PK) properties with nonlinear distribution and elimination. In recent years, several population pharmacokinetic/pharmacodynamic (PK/PD) models capable of describing different types of mAb have been published. This study aims to summarize the findings of a literature search about population PK/PD modeling and therapeutic drug monitoring (TDM) of mAb in psoriasis. A total of 22 articles corresponding to population PK/PD models of tumor necrosis factor (TNF)-α inhibitors (adalimumab and golimumab), interleukin (IL)-23 inhibitors (guselkumab, tildrakizumab, and risankizumab), IL-23/IL-12 inhibitor (ustekinumab), and IL-17 inhibitors (secukinumab, ixekizumab, and brodalumab) were collected. A summary of the clinical trials conducted so far in psoriasis was included, together with the current structural population PK and PD models. The most significant and clinical covariates were body weight (BW) and the presence of immunogenicity on clearance (CL). The lack of consensus on PK/PD relationships has prevented establishing an adequate dosage and, therefore, accentuates the need for TDM in psoriasis.

Therapeutic drug monitoring in dermatology: the way towards dose optimization of secukinumab in chronic plaque psoriasis. Clin Exp Dermatol 2022; 47:1324-1336. [PMID: 35245966 PMCID: PMC9320967 DOI: 10.1111/ced.15157] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 02/11/2022] [Accepted: 02/27/2022] [Indexed: 12/02/2022]
Abstract
Background Despite the favourable efficacy profile of secukinumab, clinicians encounter varying clinical responses among patients potentially associated with under‐ and overdosing. As biologics are expensive, their rational use is crucial and evident. Therapeutic drug monitoring could guide clinicians in making decisions about treatment modifications. Aim In this multicentre, prospective study, we aimed to develop and validate a secukinumab immunoassay and searched for the therapeutic window in patients with psoriasis. Methods We determined secukinumab concentrations at trough in sera from 78 patients with psoriasis at multiple timepoints (Weeks 12, 24, 36, 48 and 52; after Week 52, measurements could be taken at an additional three timepoints) during maintenance phase, using an in‐house secukinumab immunoassay consisting of a combination of MA‐SEC66A2 as capture antibody and MA‐SEC67A9, conjugated to horseradish peroxidase, as detecting antibody. At each hospital visit, disease severity was assessed using the Psoriasis Area and Severity Index (PASI). Results After quantification, 121 serum samples were included for dose–response analysis. Based on a linear mixed‐effects model, secukinumab trough concentrations were found to decrease with increasing body mass index (BMI). Based on receiver operating characteristic (ROC) analysis, we concluded that the minimal effective secukinumab threshold was 39.1 mg/L in steady state, and that this was associated with a 92.7% probability of having an optimal clinical response (PASI ≤ 2 or reduction in PASI of ≥ 90%). Conclusions Monitoring and targeting a secukinumab trough concentration of 39.1 mg/L may be a viable treatment option in suboptimal responders. In patients with higher BMI, weight‐based dosing may be needed in order to prevent underdosing.

Abstract
Psoriatic arthritis is an inflammatory arthritis with heterogeneous disease presentation. The most affected clinical domain of the disease determines the therapeutic approach. We report the case of a 34-year-old man with all six crucial domains of psoriatic arthritis (psoriasis, peripheral arthritis, axial skeletal manifestations, dactylitis, nail changes, and enthesitis) treated unsuccessfully with conventional synthetic DMARDs, NSAID's, and steroids as well as topical treatment and phototherapy. With golimumab as the first line of bDMARD partial remission was achieved. After 24 months the treatment was switched to secukinumab due to secondary inefficacy. The psoriasis and psoriatic arthritis relapsed after 21 months of treatment with secukinumab. The patient was cycled to ixekizumab with an excellent result. IL-17A inhibitor cycling may be a successful treatment option in some difficult to treat psoriatic arthritis patients.

Abstract
Introduction We present certolizumab pegol (CZP) efficacy data across patient demographic and baseline disease characteristic subgroups from a phase 2/3 trial investigating CZP treatment in Japanese patients with moderate to severe plaque psoriasis (PSO; ClinicalTrials.gov identifier: NCT03051217). Methods Patients were randomised 1:2:2 to placebo once every 2 weeks (Q2W), CZP 400 mg Q2W and CZP 200 mg Q2W (400 mg weeks 0, 2 and 4) for 16 weeks. Patients who achieved ≥ 50% reduction in their baseline Psoriasis Area and Severity Index (PASI 50) score at week 16 continued therapy to week 52. PASI 75/90 (75% and 90% reduction, respectively) and Physician’s Global Assessment (PGA) 0/1 responder rates at weeks 16 and 52 were reported for patient demographic and baseline disease characteristic subgroups, including body mass index (BMI), PASI, disease duration and prior biologic use. Non-responder imputation was used. Results Of the randomised patients, 2/26 patients in the placebo group, 47/53 patients in the CZP 400 mg Q2W group and and 39/48 patients in the CZP 200 mg Q2W group completed week 52. In the subgroups evaluated, week 16 efficacy was generally maintained through week 52. At week 52, PASI 75 was achieved by 84.2, 85.7 and 80.0% of patients receiving CZP 400 mg Q2W in the low (15.0–23.7 kg/m2)/intermediate (> 23.7–27.4 kg/m2)/high (> 27.4–47.0 kg/m2) BMI subgroups, respectively, and by 77.8, 70.6 and 69.2%, respectively of patients treated with CZP 200 mg Q2W. PASI 75 at week 52 was achieved by 92.9, 75.0 and 84.2% of patients receiving CZP 400 mg Q2W in the low (12.0–18.0)/intermediate (> 18.0–27.0)/high (> 27.0–67.2) baseline PASI subgroups, respectively, and by 85.0, 58.3 and 68.8% of patients receiving CZP 200 mg Q2W, respectively. Similar responses were observed across other subgroups evaluated for both CZP doses in PASI 75/90 and PGA 0/1. Conclusion Clinically meaningful improvements in signs and symptoms of PSO were maintained through week 52 for CZP dosed at 400 mg Q2W or 200 mg Q2W, across patient subgroups. In general, a numerically greater response was observed for patients receiving CZP 400 mg Q2W versus those receiving CZP 200 mg Q2W across patient subgroups.

Abstract
BACKGROUND Psoriasis is one of the most common chronic cutaneous skin disorders, having genetic and immunological components. It is currently unknown what exactly triggers it, or how far reaching are the etiological factors, although great strides have been made in uncovering the pathophysiological cascade. Presently, there is a wide diversity of treatment methods for psoriasis, yet not all are applicable for each patient. Selection of both drug and dosage depends on both the knowledge and experience of the treating dermatologist and also on the specific characteristics of each patient. Therefore, the treating physicians should be made aware of the management possibilities, their advantages and their side effects. METHODS We have performed a non-systematic literature review on the current treatment methods for psoriasis. We have included the studies, articles, and prescription information that provided the most relevant information regarding each therapeutic agent. Afterward, we divided the treatment methods according to delivery and illustrated the management protocols for adult, paediatric, and pregnant patients. DISCUSSION AND CONCLUSIONS Current therapies are divided into topical drugs, phototherapy, systemic and biological agents. Topical therapies and phototherapy are generally the first and second line of management respectively, being typically effective in treating mild to moderate forms of psoriasis. On the other hand, the chronic moderate to severe forms usually benefit from systemic drugs, whereas biologic agents are reserved for severe or unremitting cases, especially those suffering from psoriatic arthritis. Also of importance is the understanding of the pathophysiological mechanisms in psoriasis and how the selected drugs interfere in the pathological cascade. Furthermore, physicians should be able to recommend the appropriate therapy not only for adults but also for paediatric and pregnant patients as well. In the following manuscript, we present an updated version of these management options, alongside their indications, posology and most common side effects, a guide that may be useful for every practitioner in this field.

Abstract
Introduction Plaque psoriasis (PsO), characterized by demarcated, erythematous, scaly skin, can have a substantial negative impact on patients’ quality of life. This observational (non-interventional) retrospective study was conducted to characterize treatment patterns and response among patients with plaque PsO treated with secukinumab under routine medical practice in Vietnam. Methods Patient medical records from the specialized clinic of the Ho Chi Minh City Hospital of Dermato-Venereology (N = 236) were collected. Patients (male or female) aged ≥ 18 years with moderate-to-severe chronic plaque PsO, defined as > 10% involvement of the body surface area (BSA > 10) or a Psoriasis Area and Severity Index (PASI) score > 10 and a Dermatology Life Quality Index (DLQI) score > 10, were included. Results In total, 230 patients met the inclusion criteria and were included in the intention-to-treat (ITT) population, the majority of whom were men (66.1%). At baseline, the mean ± standard deviation (SD) age of the ITT population was 41.46 ± 14.29 years, mean disease duration was 7.91 ± 7.91 years, and 27% (n = 62) were obese. More than 90% of the patients were biologic naïve prior to initiation of secukinumab therapy. At week 4, 54.6% patients (n = 124) achieved ≥ 75% reduction in PASI scores from baseline (PASI 75). By week 16, 81.1, 68.9, and 36.5% of the overall population (n = 180, 153, and 81) achieved PASI scores of 75, 90, and 100, respectively; 66.1% of the overall population (n = 154) reported DLQI scores of 0/1 by week 16. The effectiveness of secukinumab was validated in subgroups of patients with or without obesity, concomitant conditions (hepatitis B virus, hepatitis C virus, diabetes, high blood pressure, gout, and/or obesity [body mass index ≥ 30 kg/m2]), and concomitant psoriatic arthritis (PsA). Conclusion The study validated the real-world effectiveness of secukinumab in Vietnamese patients irrespective of obesity, concomitant conditions, and concomitant PsA status.

Secukinumab for the treatment of psoriasis, psoriatic arthritis, and axial spondyloarthritis: Physical and pharmacological properties underlie the observed clinical efficacy and safety. Pharmacol Ther 2021; 229:107925. [PMID: 34171337 DOI: 10.1016/j.pharmthera.2021.107925] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 05/19/2021] [Accepted: 05/24/2021] [Indexed: 12/14/2022]
Abstract
Psoriasis, psoriatic arthritis, and axial spondyloarthritis are systemic inflammatory diseases, each commonly manifesting as a spectrum of symptoms, complications, and comorbidities that arise differently in individual patients. Drugs targeting inflammatory cytokines common to the pathogenesis of each of these conditions have been developed, although their specific actions in the different tissues involved are variable. For a drug to be effective, it must be efficiently delivered to and locally bioactive in disease-relevant tissues. Detailed clinical data shed light on the therapeutic effects of individual biologics on specific domains or clinical manifestations of disease and assist in guiding treatment decisions. Pharmacologic, molecular, and functional properties of drugs strongly impact their observed safety and efficacy, and an understanding of these properties provides complementary insight. Secukinumab, a fully human monoclonal IgG1/κ antibody selectively targeting interleukin (IL)-17A, has been in clinical use for >6 years in the treatment of moderate to severe psoriasis, psoriatic arthritis, and both radiographic (also known as ankylosing spondylitis) and nonradiographic axial spondyloarthritis. In this review, we discuss pharmacokinetic and pharmacodynamic data for secukinumab to introduce clinicians to the pharmacological properties of this widely used drug. Understanding how these properties affect the observed clinical efficacy, safety, and tolerability of this drug in the treatment of IL-17A-mediated systemic inflammatory diseases is important for all physicians treating these conditions.

Abstract
Background Patients with severe autosomal recessive congenital ichthyosis (ARCI) show a T helper 17/interleukin 17 (Th17/IL17) skewing in their skin and serum, resembling the inflammatory profile of psoriatic patients. Secukinumab, an IL-17A inhibitor, has shown clinical efficacy in patients with moderate-to-severe plaque psoriasis. Aims To test the clinical efficacy and safety of secukinumab in a paediatric patient with ATP-binding cassette subfamily A member 12 deficiency-related severe erythrodermic ARCI. Materials & Methods 6-months therapeutic trial. During the first 4-weeks induction period, the patient received weekly subcutaneous injections of 150 mg secukinumab (five injections in total). During the following 20-weeks maintenance period, the patient was given a subcutaneous injection of 150 mg secukinumab every 4 weeks. Result & Discussion After the 6-months therapy period, there was a 48% reduction from the baseline Ichthyosis-Area-Severity-Index (-Erythema/-Scaling) score. The treatment was well tolerated. Moreover, cytokine analysis revealed a reduction of keratinocyte-derived proinflammatory cytokines and an abrogation of Th17-skewing during therapy. Conclusion Further studies are needed to evaluate the effects of the use of IL-17A inhibition in ARCI patients.

First-in-human study demonstrating the safety and clinical efficacy of novel anti-IL-17A monoclonal antibody CJM112 in moderate to severe plaque psoriasis. J Eur Acad Dermatol Venereol 2021; 35:1143-1151. [PMID: 33617042 PMCID: PMC8246720 DOI: 10.1111/jdv.17071] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 11/13/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND AND OBJECTIVE Anti-IL-17A IgG/κ monoclonal antibody CJM112 binds both IL-17A and IL-17AF. The purpose of this First-in-Human study was to assess CJM112 effects on safety and efficacy in patients with moderate to severe plaque psoriasis. METHODS This study had two parts: single ascending doses of 5-450 mg subcutaneous (s.c.) CJM112 (SAD) and multi-dose parallel groups of CJM112 15 mg, 50 mg and 150 mg s.c. low frequency or high frequency (MD). SAD/MD were double-blind, randomized and placebo-controlled; MD also included a secukinumab 150 mg s.c. arm as an active comparator. Patients 18-65 years with moderate to severe psoriasis were included in this study. The efficacy outcome was the change in Psoriasis Area Severity Index (PASI) from baseline to Week 4 in the SAD part of the study, and from baseline to Week 12 in the MD part. RESULTS 96 patients were enrolled in this study (SAD, n = 42; MD, n = 54). In SAD, CJM112 doses from 15 mg and above demonstrated higher PASI responses compared with placebo at Week 12. CJM112 450 mg did not add further efficacy, but efficacy duration was prolonged compared with CJM112 150 mg. CJM112 MD resulted in a dose-dependent decrease in PASI over time to Week 12. CJM112 150 mg high frequency did not exceed the effect of CJM112 150 mg low frequency and had similar efficacy to secukinumab 150 mg. The safety profile of CJM112 was as expected for an antibody targeting IL-17A/IL-17AF. CONCLUSIONS CJM112 had clinical efficacy in moderate to severe psoriasis and was generally safe and well tolerated in the doses tested. Additional neutralization of IL-17AF did not translate to increased clinical efficacy compared with secukinumab.

Abstract
Background: Psoriasis is a chronic disorder with increasing new treatments targeting the T-helper cell (Th)-1/Th17 axis. There remains a subset of patients who experience a primary or secondary failure to biologic treatments.Methods: We present ten patients with psoriasis who failed biologic therapy with measurement of serum drug levels and anti-drug antibody levels (ADAs) with review of the current literature. Our objective was to identify demographic factors, disease status, drug level and ADAs which might correlate with primary and secondary failure.Results: There are a number of factors affecting drug levels in patients with psoriasis on biologics including the presence of ADAs, patient adherence to treatment regimes, pharmacogenetics and the pharmacokinetic properties of the drug following subcutaneous injection. Our results demonstrate that biologic failure is related to low serum drug levels subtherapeutic in 80% of our cohort. Primary failure may correlate with the presence of ADAs but not with serum drug levels. All patients were ANA negative and there remains considerable debate on the utility of routine ANA testing.Conclusions: The role of therapeutic drug monitoring in dermatology remains uncertain and requires further study. We aim to promote debate in the dermatology community as to the utility of therapeutic drug monitoring in routine practice.

Abstract
Background and Objectives Risankizumab is a humanized anti-interleukin-23 monoclonal antibody in development for the treatment of several inflammatory diseases. This work characterized the pharmacokinetics of risankizumab and evaluated covariates that may affect its exposures using phase I and II trial data in subjects with psoriasis and Crohn’s disease. Methods Plasma concentration measurements from a phase I study and a phase II study in subjects with psoriasis (n = 157; single doses of 0.01–5 mg/kg intravenously, 0.25–1 mg/kg subcutaneously, and 18 mg subcutaneously, and multiple doses of 90 and 180 mg subcutaneously), and a phase II study in subjects with Crohn’s disease (n = 115; doses of 200 or 600 mg intravenously every 4 weeks followed by 180 mg subcutaneously every 8 weeks) were analyzed using non-linear mixed-effects modeling. The model was qualified using bootstrap and simulation-based diagnostics. Results A two-compartment model with first-order absorption and elimination described the pharmacokinetics of risankizumab. Considering the body weight and baseline albumin central tendency differences between disease populations, risankizumab clearance, steady-state volume of distribution, and terminal-phase elimination half-life were estimated to be approximately 0.35 L/day, 11.7 L, and 27 days, respectively, for a typical 90-kg subject with psoriasis with an albumin level of 42 g/L, and 0.31 L/day, 8.45 L, and 22 days, respectively, for a typical 65-kg subject with Crohn’s disease with an albumin level of 37 g/L. Risankizumab absolute subcutaneous bioavailability and absorption rate constant were 72% and 0.18 day−1, respectively. Inter-individual variability for clearance was 37%. Conclusions Risankizumab displayed pharmacokinetic characteristics typical for an IgG1 monoclonal antibody with no apparent target-mediated disposition. Accounting for the effects of body weight and baseline albumin explained the small differences in the pharmacokinetics of risankizumab between psoriasis and Crohn’s disease, with no further differences between the patient populations.

Abstract
The molecular basis of interleukin (IL)‐17A in driving psoriasis pathogenesis is not fully elucidated yet. To investigate the underlying mechanisms and biomarkers associated with IL‐17A and the role in psoriasis pathogenesis, over 30 serum proteins were evaluated in a study assessing the effectiveness and safety of secukinumab, where treatment was directly switched from cyclosporin A to secukinumab. Serum β‐defensin 2 (BD‐2) levels rapidly and robustly reduced following secukinumab treatment. BD‐2 levels were well‐correlated with Psoriasis Area and Severity Index (PASI) score; changes in BD‐2 levels preceded change in PASI score. Serum BD‐2, an easily measurable protein, can possibly be used as a suitable surrogate biomarker to monitor responses to IL‐17A‐targeted therapies for psoriasis in clinical practice.

Abstract
AIMS The aim of the study was to compare the pharmacokinetics (PK), safety and tolerability of secukinumab with different devices for subcutaneous (s.c.) administration of 2 mL. METHODS A phase 1 study in healthy subjects with 6 devices to administer 2 mL injection volumes was conducted to evaluate the serum PK, safety and tolerability of secukinumab following single s.c. injection of 300 mg in the abdomen (either side) or in the thigh (either leg). Primary PK endpoints were maximum observed serum concentration and area under the serum concentration-time curve. The impact of device, site and side of injection on serum exposure was evaluated. In a phase 3 study in psoriasis patients, PK of secukinumab was evaluated following multiple s.c. injections of 300 mg by either 2 × 1-mL prefilled syringe or 1 × 2-mL prefilled syringe. RESULTS Mean serum concentration-time profiles for administration as 2 × 1 mL injections or as 1 × 2 mL injections were similar. With an injection volume of 2 mL, perceived injection pain was not different from 2 × 1 mL injections. A nonclinically significant difference in PK endpoints was observed between thigh and abdomen. Results with a 2 mL prefilled syringe in a 1-year phase 3 study in patients confirmed PK results observed in the phase 1 study. CONCLUSION Collective evidence from both studies demonstrated that 2-mL injections of secukinumab into the abdomen or thigh using different devices resulted in comparable PK characteristics and were all well tolerated without noticeable local reactions.

Abstract
Objective Tumor necrosis factor-alpha (TNF-α), checkpoint inhibitors, and interleukin-17 (IL-17) are critical targets in
inflammation and autoimmune diseases. Monoclonal antibodies (mAbs) have a successful portfolio in the treatment of chronic
diseases. With the current progress in stem cells and gene therapy technologies, there is the promise of replacing costly mAbs
production in bioreactors with a more direct and cost-effective production method inside the patient’s cells. In this paper we
examine the results of an investigational assessment of secukinumab gene therapy.
Materials and Methods In this experimental study, the DNA sequence of the heavy and light chains of secukinumab
antibodies were cloned in a lentiviral vector. Human chorionic villous mesenchymal stem cells (CMSCs) were isolated and
characterized. After lentiviral packaging and titration, part of the recombinant viruses was used for transduction of the CMSCs
and the other part were applied for systemic gene therapy. The engineered stem cells and recombinant viruses were applied
for ex vivo and in vivo gene therapy, respectively, in different groups of rat models. In vitro and in vivo secukinumab expression
was confirmed with quantitative real-time polymerase chain reaction (qRT-PCR), western blot, and ELISA by considering the
approved secukinumab as the standard reference.
Results Cell differentiation assays and flow cytometry of standard biomarkers confirmed the multipotency of the
CMSCs. Western blot and qRT-PCR confirmed in vitro gene expression of secukinumab at both the mRNA and protein
level. ELISA testing of serum from treated rat models confirmed mAb overexpression for both in vivo and ex vivo gene
therapies.
Conclusion In this study, a lentiviral-mediated ex vivo and in vivo gene therapy was developed to provide a moderate dose
of secukinumab in rat models. Biosimilar gene therapy is an attractive approach for the treatment of autoimmune disorders,
cancers and other chronic diseases.

Abstract
This open‐label disease‐drug–drug interaction study assessed whether blockade of the interleukin (IL)‐17A pathway by secukinumab and subsequent downregulation of inflammatory cytokines like IL‐6 or high‐sensitivity C‐reactive protein affects the pharmacokinetics (PKs) of a sensitive probe substrate of the cytochrome P450 3A4 isoform (CYP3A4). The PKs of midazolam, metabolized by CYP3A4, was evaluated before and after 7 and 35 days of treatment initiation of subcutaneous secukinumab at a dose of 300 mg weekly in 24 patients with moderate‐to‐severe psoriasis. Although demonstrating the expected decrease in downstream inflammatory cytokines, secukinumab had no clinically relevant effects on the PKs of midazolam, provided substantial clinical benefit, and was generally well tolerated. In summary, blockade of IL‐17A signaling in patients with moderate‐to‐severe psoriasis does not significantly affect CYP3A4 enzyme activities and, therefore, the use of secukinumab is unlikely to influence the PKs of CYP3A4 substrates.

Abstract
Psoriasis is a common, chronic, immune-mediated disease occurring more frequently in association with comorbid metabolic disorders. The management of patients with multiple organ dysfunction is challenging since the use of all conventional systemic agents is limited or contraindicated. In the last two decades, the introduction of biological drugs has revolutionized treatment paradigms of psoriasis and enabled numerous patients to achieve disease control with an acceptable safety profile. We reported for the first time the case of a 66-year-old female psoriatic patient affected by myocardial infarction, hypertension, chronic renal failure, hyperthyroidsm and morbid obesity, who experienced remarkable improvement in skin and joint synthoms and metabolic parameters after 48 weeks of secukinumab monotherapy. In our patient, secukinumab was well tolerated and no side effects have been observed. Our observation suggests that secukinumab could be a safe therapeutic option in patients with organ impairment or failure in which the majority of conventional systemic agents are contraindicated.

Abstract
INTRODUCTION The number of solid organ transplants completed annually continues to trend upwards each year. Despite this, maintenance immunosuppression available on the market has remained relatively stagnant. Standard triple immunosuppression, composed typically of tacrolimus, mycophenolate, and steroids, lead to many side effects that limit the use of these medications. Tacrolimus, specifically, causes nephrotoxicity that can lead to renal dysfunction requiring a kidney transplant down the road. Alternative therapies for the management of immunosuppression need to be identified to try to mitigate these adverse effects. BODY: Cytokines are responsible for facilitating T cell differentiation and lead to the activation of inflammatory mediators that can contribute to graft damage and ultimately rejection. IL-4, IL-6, IL-12/23, and IL-15 are attractive targets for medications to try to ameliorate graft rejection. Various cytokine-targeted medications are currently available on the market for the treatment of inflammatory and autoimmune conditions such as rheumatoid arthritis, psoriatic arthritis, Crohn's, and multiple sclerosis. CONCLUSION This article reviews cytokine involvement in alloimmunity and the potential role cytokine-targeted therapy may play in prevention of allograft rejection in solid organ transplant recipients.

Abstract
Atopic dermatitis is the most common chronic skin disease, and it primarily affects children. Although atopic dermatitis (AD) has the highest effect on burden of skin disease, no high-level studies have defined optimal therapy for severe disease. Corticosteroids have been used to treat AD since the 1950s and remain the only systemic medication with Food and Drug Administration approval for this indication in children, despite published guidelines of care that recommend against this option. Several clinical trials with level 1 evidence have supported the use of topical treatments for mild to moderate atopic dermatitis in adults and children, but these trials have had little consistency in protocol design. Consensus recommendations will help standardize clinical development and trial design for children. The Food and Drug Administration issues guidance documents for industry as a source for "the Agency's current thinking on a particular subject." Although they are nonbinding, industry considers these documents to be the standard for clinical development and trial design. Our consensus group is the first to specifically address clinical trial design in this population. We developed a draft guidance document for industry, Developing Drugs for Treatment of Atopic Dermatitis in Children (≥3 months to <18 years of age). This draft guidance has been submitted to the Food and Drug Administration based on a provision in the Federal Register (Good Guidance Practices).
