Abstract
Introduction: The interleukin (IL)-23 and IL-17 pathway is closely related to the pathogenesis of psoriasis. This pathway is considered to be an important target for treating psoriasis. Risankizumab can selectively inhibit IL-23p19 subunit and for the treatment of psoriasis. This article aims to review risankizumab and provides reference for clinicians. Areas covered: The chemical property, mechanism of action, pharmacokinetics, clinical efficacy, safety of risankizumab was introduced in this paper. A PubMed search using the terms 'risankizumab,' 'IL-23,' 'p19 subunit,' and 'psoriasis,' was performed, and the results were screened for the most relevant English language publications. Expert opinion: Risankizumab is a humanized IgG monoclonal antibody that binds to the p19 subunit of IL-23 and inhibits its interaction with the IL-23 receptor. Clinical trials showed that risankizumab was significantly more effective than ustekinumab. Risankizumab was well tolerated, upper respiratory tract infection was the common adverse reactions. Therefore, the market of risankizumab provides an important therapeutic means for psoriasis.

[PMID: 31212138 DOI: 10.1016/j.colsurfb.2019.06.018] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 06/07/2019] [Accepted: 06/08/2019] [Indexed: 01/10/2023]
Abstract
Supramolecular hydrogels were synthesized using a bis-imidazolium based amphiphile, and incorporating chemically diverse drugs, such as the cytostatics gemcitabine hydrochloride and methotrexate sodium salt, the immunosuppressive drug tacrolimus, as well as the corticoid drugs betamethasone 17-valerate and triamcinolone acetonide, and their potential as drug delivery agents in the dermal treatment of Psoriasis was evaluated. The rheological behavior of gels was studied, showing in all cases suitable viscoelastic properties for topical drug delivery. Scanning electron microscopy (SEM) shows that the drugs included have a great influence on the gel morphology at the microscopic level, as the incorporation of gemcitabine hydrochloride leads to slightly thicker fibers, the incorporation of tacrolimus induces flocculation and spherical precipitates, and the incorporation of methotrexate forms curled fibers. 1H NMR spectroscopy experiments show that these drugs not only remain dissolved at the interstitial space, but up to 72% of either gemcitabine or methotrexate, and up to 38% of tacrolimus, is retained within the gel fibers in gels formed with a 1:1 gelator:drug molar ratio. This unique fiber incorporation not only protects the drug from degradation, but also importantly induces a Two Phase Exponential drug release, where the first phase corresponds to the drug dissolved in the interstitial space, while the second phase corresponds to the drug exiting from the gel fibers, and where the speed in each phase is in accordance with the physicochemical properties of the drugs, opening perspectives for controlled delivery. Skin permeation ex vivo tests show how these gels successfully promote the drug permeation and retention inside the skin for reaching their therapeutic target, while in vivo experiments demonstrate that they decrease the hyperplasia and reduce the macroscopic tissue damage typically observed in psoriatic skin, significantly more than the drugs in solution. All these characteristics, beside the spontaneous and easy preparation (room temperature and soft stirring), make these gels a good alternative to other routes of administration for Psoriasis treatment, increasing the drug concentration at the target tissue, and minimizing side effects.

Abstract
INTRODUCTION Topical, systemic, oral disease modifying, and biologic agents are part of the armamentarium to manage psoriatic disease. The choice of therapy depends upon disease severity, relevant co-morbidities and patient preference. There is great variability in patient response with these agents, and there is still no clear method of selecting the preferred therapeutic agent for efficacy or lack of adverse events. AREAS COVERED This article will review the pharmacogenetic and pharmacogenomic targets that are currently known with respect to psoriasis vulgaris, and the most frequent co-morbidity of psoriasis, psoriatic arthritis. EXPERT OPINION Presently, no clinically actionable biomarker exists for any therapeutic agent used to treat psoriasis or psoriatic arthritis. The lack of validated outcome measures and conflicting results of open-label studies conducted may be attributed to a multitude of issues that confound discovery. Consequently, studies have been underpowered to identify genes or genetic variants worth translating to clinical practice. In order to achieve a pharmacogenetic/pharmacogenomic signature, improvements in study design of future investigations are required, including carefully designed prospective studies. It is imperative to combine known clinical, serological, and molecular markers with consistent outcomes and an adequate health economic evaluation before they can be adopted widely in clinical practice.

Abstract
Psoriasis is a complex genetic disease, which has previously been associated with numerous single nucleotide polymorphisms (SNPs) that are implicated in various processes, including skin barrier functions and in the regulation of inflammatory and immune responses. The present study aimed to investigate the genotypic and allelic frequencies of 32 SNPs at 24 genetic loci, and their association with psoriasis in a Mexican population. These SNPs, which were associated with psoriasis in previous studies, included the following genes: Major histocompatibility complex class I-C (HLA-C), interleukin (IL)-12B, IL-23R, IL-23A, IL-28RA, tumor necrosis factor (TNF)-α, ring finger protein-114 (RNF114), cyclin-dependent kinase 5 regulatory subunit-associated protein 1-like 1, late cornified envelope 3B/3C, signal transducer and activator of transcription 4, LINC01185, interferon induced with helicase C domain 1, IL-13, TNF-α-induced protein 3 (TNFAIP3), TNFAIP3 interacting protein 1, endoplasmic reticulum aminopeptidase 1, TNF receptor-associated factor interacting protein 2, Leptin, nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha, F-box and leucine-rich repeat protein 19, nitric oxide synthase 2, cluster of differentiation 40, nuclear receptor coactivator 5, and ADAM metallopeptidase domain 33. A total of 32 male and 14 female subjects with a clinical diagnosis of chronic plaque psoriasis, as well as 103 control subjects, were analyzed. Molecular analyses were performed using TaqMan® assays in a TaqMan® OpenArray® Genotyping system. Results were analyzed using the Golden Helix SNP and Variation Suite 7 program. Of the 32 SNPs, six were associated with an increased risk of developing psoriasis, including: HLA-C rs10484554 [allele T: odds ratio (OR) 3.51], IL-12B rs3212227 (allele T: OR 1.88), IL-12B rs3213094 (allele C: OR 1.94), HLA complex group 27 rs1265181 (allele C: OR 2.83), annexin A6 rs17728338 (allele A: OR 2.41), and RNF114 rs6125829 (allele G: OR 1.98). Fisher's exact test detected statistical significance; however, following false discovery rate and Bonferroni correction, this association was no longer significant (threshold for genome-wide significance, P<1.56×10−3). SNPs that were associated with an increased risk of psoriasis in the present study have previously been associated with psoriasis in European, American, and Asian populations. In order to establish genome-wide significance, future studies must analyze a greater sample size. To the best of our knowledge, the present pilot study is the first to investigate the association between these 32 SNPs and psoriasis in a Mexican Mestizo population.

Abstract
BACKGROUND Blocking the activity of IL-12/23 can inhibit autoimmune diseases such as psoriasis. OBJECTIVE We examined whether an antibody against IL-12/23, ustekinumab (UTZ) (Stelera®), used clinically in psoriasis would have similar anti-inflammatory effects in EAE after oral administration. DESIGN/METHODS B6 mice were immunized with MOG peptide 35-55 and gavaged with isotype IgG control or UTZ during ongoing disease. Splenocytes, CD4(+) T cells or macrophages/monocyte lineage cells (CD11b(+)) from control fed or UTZ fed mice were adoptively transferred into active MOG peptide 35-55 immunized recipient mice during ongoing disease. Actively fed and recipient mice were examined for disease inhibition, inflammation, and cytokine responses. RESULTS Ingested (oral) UTZ inhibited ongoing disease and decreased inflammation. Adoptively transferred cells from UTZ fed donors protected against actively induced disease and decreased inflammation. Oral UTZ decreased pro-inflammatory cytokines Th1-like cytokines IL-2, IL-12, IFN-γ, IL-17 (Teff) and TNF-α in UTZ fed mice and increased counter-regulatory cytokines IL-4, IL-10 and IL-13 in recipients of donor cells from UTZ fed mice. CONCLUSIONS Ingested (orally administered) UTZ can inhibit disease, CNS inflammation, decrease pro-inflammatory Th1-like and Th17 cytokines and increase Th2-like anti-inflammatory cytokines.

Abstract
There is a strong familial component to psoriatic disease as well as a complex array of genetic, immunologic, and environmental factors. The dominant genetic effect is located on chromosome 6p21.3 within the major histocompatibility complex region, accounting for one-third of genetic contribution. Genome-wide association studies (GWAS) identified additional genes, including skin barrier function, innate immune response, and adaptive immune response genes. To better understand disease susceptibility and progression requires replication in larger cohorts, fine-mapping efforts, new technologies, and functional studies of genetic variants, gene-gene interactions and gene-environmental interactions. New technologies available include next-generation sequencing, copy number variation analysis, and epigenetics.

Abstract
The authors describe the results of a study aimed at searching for new molecular targets for anticytokine therapy of patients with psoriasis. The authors examined 26 patients with psoriasis who were treated with such immune biologic substances as infliximab, ustekinumab, adalimumab and 10 healthy volunteers. They performed a quality and quantity analysis of the spectrum of protein molecules of cytokines (L-4, IL-6, IL-17, TNF-α and IL-20, IL-22, IL-31, IL-12, IL-11, IL-18) аs well as VEGF and ICAM-1 molecules in patients receiving the therapy with immune biologic substances before and after treatment using the methodology of the immune enzyme analysis and xMAP multiplex technology. The authors studied the correlation between the level of cytokine expression, on the one hand, and the occurrence and limitation of the disease, on the other hand. The obtained data are sufficient to conclude that the spectrum of molecules of IL6, IL20, IL22 anti-inflammatory cytokines аs well as VEGF and ICAM-1 molecules, for which pathogenic importance in case of psoriasis was revealed as a result of the study , may serve as a potential (new, additional) molecular target for anticytokine therapy of patients suffering with such an immune-dependent skin disease as psoriasis.

Abstract
BACKGROUND The purpose of this study was to estimate the annual and per-patient budget impact of the treatment of moderate to severe psoriasis in Greece before and after the introduction of ustekinumab. METHODS A budget impact model was constructed from a national health system perspective to depict the clinical and economic aspects of psoriasis treatment over 5 years. The model included drug acquisition, monitoring, and administration costs for both the induction and maintenance years for patients in a treatment mix with etanercept, adalimumab, infliximab, with or without ustekinumab. It also considered the resource utilization for non-responders. Greek treatment patterns and resource utilization data were derived from 110 interviews with dermatologists conducted in February 2009 and evaluated by an expert panel of 18 key opinion leaders. Officially published sources were used to derive the unit costs. Costs of adverse events and indirect costs were excluded from the analysis. Treatment response was defined as the probability of achieving a PASI 50, PASI 75, or PASI 90 response, based on published clinical trial data. RESULTS The inclusion of ustekinumab in the biological treatment mix for moderate to severe psoriasis is predicted to lead to total per-patient savings of €443 and €900 in years 1 and 5 of its introduction, respectively. The cost savings were attributed to reduced administration costs, reduced hospitalizations for non-responders, and improved efficacy. These results were mainly driven by the low number of administrations required with ustekinumab over a 5 year treatment period (22 for ustekinumab, compared with 272 for etanercept, 131 for adalimumab, and 36 for infliximab). CONCLUSIONS The inclusion of ustekinumab in the treatment of moderate to severe psoriasis in Greece is anticipated to have short- and long-term health and economic benefits, both on an annual and per-patient basis.

Abstract
Chronic plaque psoriasis is a systemic disease affecting over 3% of the population, and many patients are unsatisfied with their current treatment regimen. With advances in understanding of the pathophysiology of psoriasis, new therapeutic options are being developed. The newest of these agents, ustekinumab, offers patients rapid results and the convenience of four annual subcutaneous doses, with efficacy and safety profiles comparable with those of other biologics. However, ustekinumab has been on the market in the US for less than 2 years and will require years of extensive use before the full adverse event profile is fully understood. The purpose of this paper is to summarize the treatment options currently available for psoriasis, with an emphasis on ustekinumab in order to give prescribers an overview of the available data and allow them to make educated and informed prescribing decisions.

Abstract
Interleukin (IL)-23 is an important regulator of T helper-17 lymphocytes, which influence the cutaneous immune system by production of IL-17 and several other proinflammatory cytokines. This pathway has been recently linked to the pathogenesis of psoriasis and numerous other skin diseases. A newly developed biologic drug, ustekinumab (CNTO-1275), which targets the p40 subunit of IL-12 and IL-23, was approved by the US FDA and the European Medicines Agency in 2009 for the treatment of moderate to severe psoriasis. Administered as subcutaneous injections of 45 mg at weeks 0 and 4, and then every 12 weeks, ustekinumab produces a 75% improvement in the Psoriasis Area and Severity Index (PASI) in 66.4-75.7% of patients and a Dermatology Life Quality Index (DLQI) score of 0 or 1 in 55-56% of patients after 12 weeks of therapy. A recent clinical trial also indicates the possible efficacy of ustekinumab in psoriatic arthritis. The proportion of patients who had at least one adverse event through 12 weeks in clinical studies was 51.6-57.6% in the ustekinumab group and 50.4% in the placebo group. Serious adverse events were observed in 1.4-1.6% of patients treated with ustekinumab and in 1.4% of patients receiving placebo. Injection-site reactions occurred in 1-2% of patients and 5% of patients developed anti-ustekinumab antibodies. Further studies are needed to evaluate the long-term efficacy and safety of ustekinumab. Another biologic drug that targets the same molecules, briakinumab (ABT-874), has recently had its approval application withdrawn in the US and Europe to conduct further analysis and clinical trials. The company plans resubmission at a later date. Other IL-23 pathway inhibitors in the pipeline include anti-p19 monoclonal antibody and apilimod (STA-5326), which interfere with IL-23 activity, as well as secukinumab (AIN-457), LY-2439821, and AMG-827, which exhibit their activity at other targets of the IL-23 pathway.

Abstract
Psoriasis is an inflammatory hyperproliferative skin disorder with a strong genetic predisposition. While many effective modalities are currently available for treating psoriasis, response to therapy is quite variable among patients. The genetic component underlying the response to pharmacotherapy in psoriasis is slowly beginning to emerge and represents a specialized field of genetics referred to as pharmacogenetics. The identification of genetic variants has the potential to improve the management of patient care by identifying which patients should avoid a specific drug and which patients should be administered a modified dose. A suitable approach in implementing such a strategy could potentially reduce medical costs and improve success of drug therapy. This article summarizes the clinical aspects of psoriasis, its genetic susceptibility and highlights the current landscape of genetic targets for psoriasis pharmacotherapy.

Abstract
The choice of therapeutic agents for patients with moderate-to-severe psoriasis has expanded significantly in the past decade. With new understanding of the immunologic basis of psoriasis, multiple new potential targets for therapy have been identified. It is likely that a series of new medications to focus on the newly identified pathways is on the horizon. The first pathway targeted by new medications focuses on the p40 subunit that is shared by interleukin (IL)-12 and IL-23. Two human anti-p40 antibodies have been used therapeutically in psoriasis to date, ustekinumab (CNTO-1275, Stelara, Centocor, Horsham, PA) and briakinumab (ABT-874, Abbott, Abbott Park, IL). Ustekinumab was recently approved by the United States Food and Drug Administration, making it the first medication approved in the United States to work by this pathway while briakinumab is currently in phase III clinical trials.

Abstract
Treating multiple sclerosis (MS) with monoclonal antibodies (mAbs) has been marked by both progress and setbacks in the past 2 years, which are reviewed here. The natalizumab section of the article centers around progressive multifocal leukoencephalopathy (PML), and discusses PML risk in relation to treatment duration, bioassays for individual risk prediction, the concept of drug holidays, clinical course and treatment of PML, as well as safety-related regulatory actions. The rituximab section critically analyzes recent clinical trial results, discusses the clinical relevance of anti-idiotypic mAbs and makes a short excursion to neuromyelitis optica. Following this, the newer anti-CD20 mAbs ocrelizumab and ofatumumab, which are currently being tested in Phase II for MS, are reviewed and compared. The alemtuzumab section highlights novel data on mechanisms of action, potentially allowing individual risk prediction, and new results from the CAMMS223 trial, as well as the current status of the pivotal MS studies. The daclizumab section summarizes new open-label data, shedding more light on the adverse-effect profile of the drug in MS patients, and reports on its Phase III status. Subsequently, a failed ustekinumab trial and LY2127399 are reviewed. Taking into account late Phase II and III data on novel oral agents, the final section attempts to provide a detailed perspective on disease-modifying MS therapy in the medium term.

Abstract
The pathogenesis of psoriasis is unknown, although it is generally accepted that this chronic inflammatory skin disorder is a complex autoimmune condition similar to other T-cell mediated disorders. Psoriasis imposes a heavy burden on the lifestyle of those affected due to the psychological, arthritic, and cutaneous morbidities; thus significant research has focused on the genetic and immunologic features of psoriasis in anticipation of more targeted, efficacious, and safe therapies. Recently, CD4(+) T helper (Th) 17 cells and interleukins (IL)-12 and -23 have been important in the pathogenesis of T-cell mediated disorders such as psoriasis and has influenced the development of medications that specifically target these key immunological players. Ustekinumab is a monoclonal antibody belonging to a newly developed class of biological, anti-cytokine medications that notably targets the p40 subunit of both IL-12 and -23, both naturally occurring proteins that are important in regulating the immune system and are understood to play a role in immune-mediated inflammatory disorders. Ustekinumab's safety and efficacy has been evaluated for the treatment of moderate-to-severe plaque psoriasis in 3 phase III clinical trials, 2 placebo-controlled (PHOENIX 1 and 2), and 1 comparator-controlled (ACCEPT) study which proved advantageous in patients who were treatment-naive, previously failed other immunosuppressive medications including cyclosporine or methotrexate, were unresponsive to phototherapy, or were unable to use or tolerate other therapies. Ustekinumab has also been investigated for other indications such as psoriatic arthritis, Crohn's disease, and relapsing/remitting multiple sclerosis. We present a concise review evaluating the evidence that supports the use of ustekinumab in the treatment of plaque psoriasis and other conditions.

Abstract
BACKGROUND AND PURPOSE Apremilast is an orally administered phosphodiesterase-4 inhibitor, currently in phase 2 clinical studies of psoriasis and other chronic inflammatory diseases. The inhibitory effects of apremilast on pro-inflammatory responses of human primary peripheral blood mononuclear cells (PBMC), polymorphonuclear cells, natural killer (NK) cells and epidermal keratinocytes were explored in vitro, and in a preclinical model of psoriasis. EXPERIMENTAL APPROACH Apremilast was tested in vitro against endotoxin- and superantigen-stimulated PBMC, bacterial peptide and zymosan-stimulated polymorphonuclear cells, immunonoglobulin and cytokine-stimulated NK cells, and ultraviolet B light-activated keratinocytes. Apremilast was orally administered to beige-severe combined immunodeficient mice, xenotransplanted with normal human skin and triggered with human psoriatic NK cells. Epidermal skin thickness, proliferation index and inflammation markers were analysed. KEY RESULTS Apremilast inhibited PBMC production of the chemokines CXCL9 and CXCL10, cytokines interferon-gamma and tumour necrosis factor (TNF)-alpha, and interleukins (IL)-2, IL-12 and IL-23. Production of TNF-alpha by NK cells and keratinocytes was also inhibited. In vivo, apremilast significantly reduced epidermal thickness and proliferation, decreased the general histopathological appearance of psoriasiform features and reduced expression of TNF-alpha, human leukocyte antigen-DR and intercellular adhesion molecule-1 in the lesioned skin. CONCLUSIONS AND IMPLICATIONS Apremilast displayed a broad pattern of anti-inflammatory activity in a variety of cell types and decreased the incidence and severity of a psoriasiform response in vivo. Inhibition of TNF-alpha, IL-12 and IL-23 production, as well as NK and keratinocyte responses by this phosphodiesterase-4 inhibitor suggests a novel approach to the treatment of psoriasis.
