Abstract
This study investigated the pharmacokinetics of tofacitinib in rats and the effects of first-pass metabolism on tofacitinib pharmacokinetics. Intravenous administration of 5, 10, 20, and 50 mg/kg tofacitinib showed that the dose-normalized area under the plasma concentration-time curve from time zero to infinity (AUC) was significantly higher at 50 mg/kg than at lower doses, a difference possibly due to saturation of the hepatic metabolism of tofacitinib. Oral administration of 10, 20, 50, and 100 mg/kg tofacitinib showed that the dose-normalized AUC was significantly higher at 100 mg/kg than at lower doses, a difference possibly due to saturation of the intestinal metabolism of tofacitinib. Following oral administration of 10 mg/kg tofacitinib, the unabsorbed fraction from the rat intestine was 3.16% and the bioavailability (F) was 29.1%. The AUC was significantly lower (49.3%) after intraduodenal, compared to intraportal, administration, but did not differ between intragastric and intraduodenal administration, suggesting that approximately 46.1% of orally administered tofacitinib was metabolized through an intestinal first-pass effect. The AUC was also significantly lower (42%) after intraportal, compared to intravenous, administration, suggesting that the hepatic first-pass effect on tofacitinib after entering the portal vein was approximately 21.3% of the oral dose. Taken together, these findings suggest that the low F of tofacitinib is due primarily to intestinal first-pass metabolism.

Abstract
INTRODUCTION Psoriasis and psoriatic arthritis (PsA) are inflammatory immune-mediated conditions which can cause considerable disability and reduced quality of life. Management can be complex as clinical heterogeneity may lead to different treatment pathways. Tofacitinib is a novel, oral Janus Kinase (JAK) inhibitor with proven efficacy in rheumatoid arthritis. Areas covered: This review analyzes recent studies of tofacitinib in psoriatic disease treatment. The relevant literature was identified using clinicaltrials.gov, PubMed, and Google Scholar. Tofacitinib efficacy was demonstrated in PsA by the OPAL Broaden and OPAL Beyond phase-III studies, and received FDA and EMA approval. Tofacitinib was superior to placebo for the treatment of moderate-to-severe plaque psoriasis in the OPT Pivotal 1 and 2, OPT Retreatment studies, but FDA approval was declined for this indication based on issues of clinical efficacy and long-term safety. Expert commentary: Tofacitinib is an important oral drug for the treatment of PsA. However, the long-term safety data require further evaluation. Tofacitinib and other JAK inhibitors show potential to broaden the treatment options in PsA and other inflammatory conditions.

Abstract
BACKGROUND Knee osteoarthritis (KOA) is a common chronic musculoskeletal disorder that seriously affects quality of life. Patients with KOA frequently develop one or more of the following typical symptoms: joint pain, stiffness, joint friction noise and impaired functionality. Traditional Chinese medicine (TCM) has been shown to have a superior effect and a particular advantage in the treatment of KOA; among TCM, the Tong-luo Qu-tong plaster is the convenient and most commonly used method in China to improve symptoms including pain, stiffness and limited mobility in patients with KOA, as it causes few adverse effects. But there is a lack of high-quality clinical evidences to support the therapeutic effect that Chinese adhesive plaster can have in relieving pain and stiffness. The purpose of this study will be to evaluate the efficacy and safety of Tong-luo Qu-tong plaster in patients with KOA. METHODS/DESIGN This study will be a randomized, double-blind, parallel positive controlled, multi-center clinical trial, a non-inferiority trial design was adopted. A total of 2000 participants older than 40 years, with KOA, will be randomly allocated into an experimental group (n = 1500) and a control group (n = 500). All participants will receive a conventional conservative treatment lasting for 14 days as two courses, once daily. Tong-luo Qu-tong plaster will be administered externally to participants in the experimental group, while the control group will receive a Qi-zheng Xiao-tong plaster. The outcome of the total Western Ontario and McMaster Universities Arthritis Index scores, TCM syndrome quantitative score and visual analog scale scores will be measured during the assessment visits (baseline and 1-week and 2-week follow up). In addition, adverse events related to clinical symptoms and signs and results of laboratory tests will be documented during the clinical trials. DISCUSSION This study will provide reliable evidence of the effectiveness and safety of Tong-luo Qutong plaster in patients with KOA. If the results are favorable, it is expected that the patients with KOA will benefit from this study, many patients may have a good alternative treatment for KOA.

Abstract
BACKGROUND Several different Physician Global Assessment (PGA) versions have been used in clinical studies as a co-primary end point to evaluate psoriasis severity. Tofacitinib is an oral Janus kinase inhibitor. We performed an analysis of the PGA using data from studies of tofacitinib in moderate to severe chronic plaque psoriasis. METHODS Data from 3641 patients with moderate to severe chronic plaque psoriasis, enrolled in one of four phase III tofacitinib studies (OPT Pivotal 1 and 2, OPT Compare and OPT Retreatment), were used to evaluate a three-item PGA scale. RESULTS Confirmatory Factor Analyses showed that equal weighting of the three items (erythema, induration and scaling) was appropriate. The PGA demonstrated acceptable test-retest reliability (Intraclass Correlation Coefficient, 0.7) and internal consistency (Cronbach's Coefficient Alpha ≥ 0.9 at primary time points). The Clinically Important Difference was estimated as 0.55 (95% confidence interval: 0.546-0.563). Known-group validity was shown by demonstrating that PGA scores could discriminate between different degrees of disease severity. The PGA was significantly correlated with other clinical end points in the studies (Psoriasis Area and Severity Index, r = 0.75-0.79; Dermatology Life Quality Index, r = 0.44-0.57; Patient Global Assessment, r = 0.66-0.72). CONCLUSIONS Consistent with previous findings from a phase II study, these results indicate that this PGA is a valid, reliable instrument for evaluating disease severity in clinical studies of psoriasis.

Abstract
Background Tofacitinib is an oral Janus kinase (JAK) inhibitor that targets JAK1 and JAK3, and thus regulates immune response. Therefore, tofacitinib is used to treat immune-mediated inflammatory diseases such as chronic plaque psoriasis. The objective of this study was to systematically assess the efficacy and safety of tofacitinib in treating chronic plaque psoriasis. Objective To systematically review the efficacy and safety of tofacitinib in the treatment of chronic plaque psoriasis, we performed a meta-analysis to evaluate the efficacy and safety of tofacitinib in patients with chronic plaque psoriasis. Methods Databases including PubMed, Embase, and The Cochrane Library were searched for randomized controlled trials about the efficacy and safety of tofacitinib in treating chronic plaque psoriasis from inception to August 2017 (PROSPERO Code No: CRD42017076587). Results Six articles (seven randomized controlled trial studies) involving 3743 patients were included. The meta-analysis results showed that for efficacy, tofacitinib (5 mg or 10 mg) compared with placebo can significantly improve the Physician’s Global Assessment response, PASI75, and PASI90 after treatment. For safety, the incidence of adverse reactions was statistically significantly higher for tofacitinib compared with placebo. Conclusion Treatment of chronic plaque psoriasis with tofacitinib is effective, but there may be more adverse reactions.

Abstract
Psoriasis has historically been considered a nonpruritic dermatosis, in contrast with atopic dermatitis. Thus, itch has often been underappreciated and overlooked in psoriasis. However, increasing evidence over the past decade has shown that itch can be one of the most prevalent and burdensome symptoms associated with psoriasis, affecting almost every patient to some degree. Itch can involve the entire body, although it predominantly affects the legs, hands, back, body and especially the scalp. Uncontrolled itch can significantly impact all aspects of the well-being and quality of life of the patient. While there has been some progress in trying to better understand the pathophysiology of itch in psoriasis, more research effort and interest are needed. This under-recognition of itch in psoriasis is clearly reflected in the dearth of treatment options targeting itch despite significant advancement in treating the lesions themselves. Recently, however, clinical studies have begun to include itch as a study outcome. The resulting data have demonstrated concomitant antipruritic benefits and improved Psoriasis Area and Severity Index (PASI) scores with mainstay treatments for psoriasis, such as topical corticosteroids and vitamin D analogs, phototherapies, and various systemics and biologics. This article takes a closer look at this debilitating symptom, reviewing the available epidemiology data for psoriatic itch, presenting the current understanding of psoriatic itch pathophysiology and highlighting important clinical data for various treatment options for itch. Practical considerations for increasing the recognition of itch as well as improving its management in psoriasis are also provided.

Abstract
Atopic dermatitis (AD) is one of the most common inflammatory skin diseases. AD is driven by barrier dysfunction and abnormal immune activation of T helper (Th) 2, Th22, and varying degrees of Th1 and Th17 among various subtypes. The Janus kinase (JAK)-signal transducer and activator of transcription (STAT) and spleen tyrosine kinase (SYK) pathways are involved in signaling of several AD-related cytokines, such as IFN-γ, IL-4, IL-13, IL-31, IL-33, IL-23, IL-22, and IL-17, mediating downstream inflammation and barrier alterations. While AD is primarily Th2-driven, the clinical and molecular heterogeneity of AD endotypes highlights the unmet need for effective therapeutic options that target more than one immune axis and are safe for long-term use. The JAK inhibitors, which target different combinations of kinases, have overlapping but distinct mechanisms of action and safety profiles. Several topical and oral JAK inhibitors have been shown to decrease AD severity and symptoms. A review of the JAK and SYK inhibitors that are currently undergoing evaluation for efficacy and safety in the treatment of AD summarizes available data on a promising area of therapeutics and further elucidates the complex molecular interactions that drive AD.

Abstract
Obesity and hyperlipidemia are the most prevalent independent risk factors of chronic kidney disease (CKD), suggesting that lipid accumulation in the renal parenchyma is detrimental to renal function. Non-esterified fatty acids (also known as free fatty acids, FFA) are especially harmful to the kidneys. A concerted, increased FFA uptake due to high fat diets, overexpression of fatty acid uptake systems such as the CD36 scavenger receptor and the fatty acid transport proteins, and a reduced β-oxidation rate underlie the intracellular lipid accumulation in non-adipose tissues. FFAs in excess can damage podocytes, proximal tubular epithelial cells and the tubulointerstitial tissue through various mechanisms, in particular by boosting the production of reactive oxygen species (ROS) and lipid peroxidation, promoting mitochondrial damage and tissue inflammation, which result in glomerular and tubular lesions. Not all lipids are bad for the kidneys: polyunsaturated fatty acids (PUFA) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) seem to help lag the progression of chronic kidney disease (CKD). Lifestyle interventions, especially dietary adjustments, and lipid-lowering drugs can contribute to improve the clinical outcome of patients with CKD.

Abstract
Despite the great success in the diagnosis and treatment of immuno-inflammatory rheumatic diseases (IIRD), which led to a significant improvement in the prognosis in many patients, the fundamental medical problems of this pathology – the restoration of quality of life and reduction of mortality to the population level – are far from solution. This served as a powerful impetus to the study of new approaches to pharmacotherapy of IIRD, one of which is associated with the use of low-molecular synthetic drugs that inhibit intracellular "signal" molecules-Janus kinase (JAK), the socalled Jakinibs. The current achievements and trends concerning the use of JAK inhibitors in the treatment of IIRD are considered.

Abstract
BACKGROUND Herpes zoster (HZ) incidence is linked to immunosuppression. Patients with psoriasis or psoriatic arthritis (PsA) on systemic therapy might be at an increased risk for HZ. OBJECTIVE To assess HZ risk in patients with psoriasis and PsA by systemic treatment and provide recommendations regarding HZ vaccination. METHODS A systematic literature search was performed for HZ in patients with psoriasis and PsA. HZ vaccination guidelines were reviewed, and the medical board of the National Psoriasis Foundation made consensus recommendations in psoriasis and PsA patients using graded evidence. RESULTS In total, 41 studies met inclusion criteria. Systemic corticosteroids (strong, 1), tofacitinib (strong, 1), and combination therapy with biologic and conventional synthetic disease-modifying antirheumatic drugs (weak, 2a) carry increased HZ risk while monotherapy does not. There is insufficient evidence to determine risk with interleukin 12/23, 17, and 23 inhibitors or apremilast (weak, 2a). Recombinant zoster vaccine is recommended for all psoriasis and PsA patients >50 years old and patients <50 years old on tofacitinib, systemic steroids, or combination systemic treatment. Vaccination of patients <50 years old on other systemic therapies may be considered on a case-by-case basis. LIMITATIONS There was significant heterogeneity between studies. CONCLUSION HZ risk depends on disease severity and treatment class. Recombinant zoster vaccine should be given to all psoriasis and PsA patients >50 years old and younger patients at increased risk.

Abstract
Cytokines, many of which signal through the JAK-STAT (Janus kinase-Signal Transducers and Activators of Transcription) pathway, play a central role in the pathogenesis of inflammatory and autoimmune diseases. Currently three JAK inhibitors have been approved for clinical use in USA and/or Europe: tofacitinib for rheumatoid arthritis, psoriatic arthritis and ulcerative colitis, baricitinib for rheumatoid arthritis, and ruxolitinib for myeloproliferative neoplasms. The clinical JAK inhibitors target multiple JAKs at high potency and current research has focused on more selective JAK inhibitors, almost a dozen of which currently are being evaluated in clinical trials. In this narrative review, we summarize the status of the pan-JAK and selective JAK inhibitors approved or in clinical trials, and discuss the rationale for selective targeting of JAKs in inflammatory and autoimmune diseases.

Abstract
Objective The objective was to investigate the short-term risk of major adverse cardiovascular events (MACEs) or congestive heart failure (CHF) in patients with psoriatic arthritis (PsA) or psoriasis initiating a biological therapy. Methods Screening for the study was carried out using MEDLINE, Cochrane and Embase, from the inception of the database to December 2017. Randomised controlled trials (RCTs) of anti-tumour necrosis factor (TNF), anti-interleukin (IL)12/23, anti-IL23 and anti-IL17 agents for the treatment of PsA or psoriasis were included. Two investigators independently extracted MACEs or CHF data reported during the placebo-controlled phase. The primary outcome measures were the incidence of MACEs or CHF. Results Of 753 references screened, 62 articles were selected, and 12 articles were added by manual searches. Accordingly 77 RCTs were included in the meta-analysis (MA) (10 174 patient-years (P-Y)). No significant difference was observed in MACE incidences in patients receiving anti-TNF, anti-IL12/23, anti-IL23 or anti-IL17 agents in comparison to the placebo. However, 10 MACEs were observed in the anti-IL12/23 group (1150 P-Y) compared with 1 in the placebo group (652 P-Y), with 0.01 -0.00 to 0.02 event/P-Y risk difference, which is not statistically significant. This trend was not observed in the anti-IL23 group. No significant difference was observed in CHF incidence in patients receiving biological agents in comparison to placebo. Conclusion This MA of 77 RCTs did not reveal any significant change in the short-term risk of MACE or CHF in patients with PsA or psoriasis initiating a biological therapy.

Abstract
Background: Guselkumab is an interleukin-23 inhibitor indicated for treatment of moderate-to-severe plaque psoriasis. Objective: The objective was to determine the relative efficacy and safety of guselkumab compared to other biologics. Methods: A systematic review was performed to identify randomized controlled trials (RCTs). Bayesian network meta-analyses (NMAs) were conducted using meta-regression analyses that adjusted for cross-trial differences and risk differences. The primary outcome was Psoriasis Area and Severity Index (PASI) 90 response. Other efficacy and safety outcomes were considered. Several meta-regressions were performed to account for variations in patient and study characteristics: baseline risk adjustment (ie, control group response), prior biologic use, duration of psoriasis, weight, age, race, and baseline PASI/dermatology life quality index scores. The best-fitting model using predefined criteria was selected. Results: Forty-five RCTs were identified. Patient and study characteristics differed between RCTs as reflected in variations in control group response. Both the baseline risk-adjusted NMA and the risk-difference NMA fit the data best and suggested guselkumab has one of the highest PASI 90 responses. Pairwise comparisons from the baseline risk-adjusted PASI 90 NMA suggested guselkumab has comparable efficacy with ixekizumab (relative risk [RR]: 0.999, 95% credible intervals [CrIs]: 0.89-1.13) and brodalumab (RR: 1.04, 95% CrIs: 0.91-1.17) and superior efficacy versus all other treatments in the network (RR range, 1.20 to 43.22). Guselkumab was superior or comparable to other therapies for other efficacy outcomes and had a more favorable safety profile than most. Conclusions: Guselkumab has one of the highest PASI 90 responses among psoriasis treatments; similar findings were observed for other efficacy outcomes. Guselkumab has a favorable benefit–risk balance compared to moderate-to-severe psoriasis therapies.

Abstract
Immunosuppressants have shown striking achievements in treating autoimmune diseases in recent years. It is urgent to develop more immunosuppressants to provide more options for patients. PO-296 [2-(6-chlorobenzo[d]oxazol-2-yl)-4,5,6,7-tetrahydro-2H-indazol-3-ol] was identified as a novel benzoxazole derivative. We observed that it exhibits an obvious immunosuppressive activity to T lymphocytes. PO-296 significantly inhibited the proliferation of activated human T lymphocyte without cytotoxicity. Moreover, PO-296 did not affect the expression of cluster of differentiation (CD)-25 or CD69 but induced T lymphocyte cycle arrest in the G0/G1 phase. Furthermore, PO-296 inhibited interleukin (IL)-6, IL-17, and interferon gamma expression but had no effect on IL-2, IL-4, or IL-10. Yet, importantly, PO-296 inhibited the phosphorylation of signal transducer and activator of transcription 5 (STAT5), increased the phosphorylation of p70S6K, but did not affect the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mitogen-activated protein kinase pathway. In conclusion, these findings indicate that PO-296 inhibits human activated T-lymphocyte proliferation by affecting the janus kinase 3 (JAK3)/STAT5 pathway. PO-296 possesses a potential lead compound for the design and development of new immunosuppressants for the treatment of autoimmune diseases.

Abstract
BACKGROUND Active inflammatory bowel disease increases the risk of adverse pregnancy outcomes. Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). As a small molecule, tofacitinib is likely to cross the placental barrier; however, information on the effects of tofacitinib on pregnancy outcomes is limited. We report pregnancy and newborn outcomes among patients in UC clinical studies with prenatal (maternal/paternal) exposure to tofacitinib. METHODS Pregnancies with maternal/paternal exposure to tofacitinib were identified and outcomes reported in 5 tofacitinib UC interventional studies (up to March 2017). Outcomes from tofacitinib rheumatoid arthritis (RA), psoriasis, and psoriatic arthritis interventional studies, and RA noninterventional postapproval safety studies, spontaneous adverse event reporting, and registry data are also reported. RESULTS Of 1157 patients enrolled in the UC interventional studies, 301 were women of childbearing age. Eleven cases of maternal exposure and 14 cases of paternal exposure to tofacitinib (doses of 5 mg or 10 mg twice daily) before/at the time of conception or during pregnancy were identified. Outcomes included 15 healthy newborns, no fetal deaths, no neonatal deaths, no congenital malformations, 2 spontaneous abortions, and 2 medical terminations. Outcomes across other tofacitinib studies and postmarketing cases were consistent, with a healthy newborn being the most common outcome and no fetal deaths. CONCLUSIONS Based on the limited data available, pregnancy and newborn outcomes among patients with prenatal (maternal/paternal) exposure to tofacitinib in UC studies appear similar to those reported for other tofacitinib clinical study populations and the general population.

Abstract
OBJECTIVE To develop an evidence-based guideline for the pharmacologic and nonpharmacologic treatment of psoriatic arthritis (PsA), as a collaboration between the American College of Rheumatology (ACR) and the National Psoriasis Foundation (NPF). METHODS We identified critical outcomes in PsA and clinically relevant PICO (population/intervention/comparator/outcomes) questions. A Literature Review Team performed a systematic literature review to summarize evidence supporting the benefits and harms of available pharmacologic and nonpharmacologic therapies for PsA. GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to rate the quality of the evidence. A voting panel, including rheumatologists, dermatologists, other health professionals, and patients, achieved consensus on the direction and the strength of the recommendations. RESULTS The guideline covers the management of active PsA in patients who are treatment-naive and those who continue to have active PsA despite treatment, and addresses the use of oral small molecules, tumor necrosis factor inhibitors, interleukin-12/23 inhibitors (IL-12/23i), IL-17 inhibitors, CTLA4-Ig (abatacept), and a JAK inhibitor (tofacitinib). We also developed recommendations for psoriatic spondylitis, predominant enthesitis, and treatment in the presence of concomitant inflammatory bowel disease, diabetes, or serious infections. We formulated recommendations for a treat-to-target strategy, vaccinations, and nonpharmacologic therapies. Six percent of the recommendations were strong and 94% conditional, indicating the importance of active discussion between the health care provider and the patient to choose the optimal treatment. CONCLUSION The 2018 ACR/NPF PsA guideline serves as a tool for health care providers and patients in the selection of appropriate therapy in common clinical scenarios. Best treatment decisions consider each individual patient situation. The guideline is not meant to be proscriptive and should not be used to limit treatment options for patients with PsA.

Abstract
OBJECTIVE To develop an evidence-based guideline for the pharmacologic and nonpharmacologic treatment of psoriatic arthritis (PsA), as a collaboration between the American College of Rheumatology (ACR) and the National Psoriasis Foundation (NPF). METHODS We identified critical outcomes in PsA and clinically relevant PICO (population/intervention/comparator/outcomes) questions. A Literature Review Team performed a systematic literature review to summarize evidence supporting the benefits and harms of available pharmacologic and nonpharmacologic therapies for PsA. GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to rate the quality of the evidence. A voting panel, including rheumatologists, dermatologists, other health professionals, and patients, achieved consensus on the direction and the strength of the recommendations. RESULTS The guideline covers the management of active PsA in patients who are treatment-naive and those who continue to have active PsA despite treatment, and addresses the use of oral small molecules, tumor necrosis factor inhibitors, interleukin-12/23 inhibitors (IL-12/23i), IL-17 inhibitors, CTLA4-Ig (abatacept), and a JAK inhibitor (tofacitinib). We also developed recommendations for psoriatic spondylitis, predominant enthesitis, and treatment in the presence of concomitant inflammatory bowel disease, diabetes, or serious infections. We formulated recommendations for a treat-to-target strategy, vaccinations, and nonpharmacologic therapies. Six percent of the recommendations were strong and 94% conditional, indicating the importance of active discussion between the health care provider and the patient to choose the optimal treatment. CONCLUSION The 2018 ACR/NPF PsA guideline serves as a tool for health care providers and patients in the selection of appropriate therapy in common clinical scenarios. Best treatment decisions consider each individual patient situation. The guideline is not meant to be proscriptive and should not be used to limit treatment options for patients with PsA.

Abstract
The skin provides both a physical barrier and an immunologic barrier to external threats. The protective machinery of the skin has evolved to provide situation-specific responses to eliminate pathogens and to provide protection against physical dangers. Dysregulation of this machinery can give rise to the initiation and propagation of inflammatory loops in the epithelial microenvironment that result in inflammatory skin diseases in susceptible people. A defective barrier and microbial dysbiosis drive an interleukin 4 (IL-4) loop that underlies atopic dermatitis, while in psoriasis, disordered keratinocyte signaling and predisposition to type 17 responses drive a pathogenic IL-17 loop. Here we discuss the pathogenesis of atopic dermatitis and psoriasis in terms of the epithelial immune microenvironment-the microbiota, keratinocytes and sensory nerves-and the resulting inflammatory loops.

Abstract
Introduction: Psoriasis is an immune-mediated skin disease amenable to targeted immunotherapy. Tildrakizumab is a humanized IgG1 monoclonal antibody targeting interleukin-23 p19 and is approved for use in moderate to severe psoriasis. Areas covered: This article reviews the mechanism of action, pharmacokinetics, safety, tolerability, and clinical efficacy of tildrakizumab, administered subcutaneously every 12 weeks, in treatment of moderate to severe psoriasis. Expert commentary: In two phase 3 clinical trials, tildrakizumab showed a consistent low occurrence of adverse events, underlining safety and tolerance. The long half-life permits subcutaneous injections every 12 weeks. Seventy eight percent of patients achieved PASI 75 (a > 75% improvement from baseline PASI) at 28 weeks, 58% achieved PASI 90, 29% achieved PASI 100 and 70% achieved a Physician's Global Assessment score of clear or almost clear. A high proportion of patients maintained PASI response after 2 years of treatment. Tildrakizumab improved Dermatology Life Quality Index, psoriasis-related personal relationship problems and sexual difficulties. Baseline PASI score, PGA, and BMI were not predictive of PASI 90 response at week 12, however achievement of PASI 50 by week 8 was predictive of a PASI 90 response at week 12.

Abstract
Aim: The importance of adjusting for cross-study heterogeneity when conducting network meta-analyses (NMAs) was demonstrated using a case study of biologic therapies for moderate-to-severe plaque psoriasis. Methods: Bayesian NMAs were conducted for Psoriasis Area and Severity Index 90 response. Several covariates were considered to account for cross-trial differences: baseline risk (i.e., placebo response), prior biologic use, body weight, psoriasis duration, age, race and baseline Psoriasis Area and Severity Index score. Model fit was evaluated. Results: The baseline risk-adjusted NMA, which adjusts for multiple observed and unobserved effect modifiers, was associated with the best model fit. Lack of adjustment for cross-trial differences led to different clinical interpretations of findings. Conclusion: Failure to adjust for cross-trial differences in NMA can have important implications for clinical interpretations when studying the comparative efficacy of healthcare interventions.

Abstract
BACKGROUND There is a significant need for novel, safe, and efficacious topical treatments for psoriasis. OBJECTIVE We assessed the safety and efficacy of tapinarof in a new cream formulation at 2 concentrations and with 2 application frequencies in adults with psoriasis. METHODS Double-blind, vehicle-controlled, randomized, 6-arm trial (1:1:1:1:1:1) in adults, with psoriasis with body surface involvement ≥1% and ≤15% and Physician Global Assessment (PGA) score ≥2 at baseline. Primary endpoint included PGA of 0 or 1 at week 12 and a 2-grade improvement from baseline. Additional analyses included assessment of ≥75% improvement of Psoriasis Area and Severity Index and mean percent change in Psoriasis Area and Severity Index and body surface area involvement. RESULTS Treatment success defined by PGA 0 or 1 and a 2-grade improvement at week 12 was statistically significantly higher (at a .05 significance level) in the tapinarof groups (65% [1% twice daily], 56% [1% once daily], 46% [0.5% twice daily], and 36% [0.5% once daily]) than in the vehicle groups (11% [twice daily] and 5% [once daily]) and was maintained for 4 weeks posttreatment. Treatment-emergent adverse events were more frequent in patients treated with tapinarof (85/152, 56%) than vehicle (19/75, 25%) and mild-to-moderate in intensity. Severe treatment-emergent adverse events were reported in all tapinarof groups except the 0.5% once daily group. LIMITATIONS Large confirmation trials are needed. CONCLUSIONS Tapinarof cream is efficacious and well tolerated in adult patients with psoriasis.

Abstract
Background Although existing psoriasis treatments are effective and well tolerated in many patients, there is still a need for new effective targeted treatment options. Tofacitinib is an oral Janus kinase inhibitor that has been investigated in patients with moderate‐to‐severe chronic plaque psoriasis. Objectives To consider the benefits and risks of tofacitinib in patients with moderate‐to‐severe psoriasis. Methods Data were pooled from one phase II, four phase III and one long‐term extension study comprising 5204 patient‐years of tofacitinib treatment. Efficacy end points included patients achieving Physician's Global Assessments of ‘clear’ or ‘almost clear’, ≥ 75% and ≥ 90% reduction in Psoriasis Area and Severity Index (coprimary end points) and improvements in Dermatology Life Quality Index score, Hospital Anxiety and Depression Scale depression score and Itch Severity Item score, at weeks 16 and 52. Safety data were summarized for 3 years of tofacitinib exposure. Results Tofacitinib 5 and 10 mg twice daily (BID) showed superiority over placebo for all efficacy end points at week 16, with response maintained for 52 weeks of continued treatment. Tofacitinib improved patients’ quality of life and was well tolerated. Rates of safety events of interest (except herpes zoster) were similar to those in the published literature and healthcare databases for other systemic psoriasis therapies. Tofacitinib 10 mg BID demonstrated greater efficacy than 5 mg BID. Conclusions Tofacitinib has a benefit–risk profile in moderate‐to‐severe psoriasis consistent with that of other systemic treatments. What's already known about this topic? Psoriasis is a chronic, systemic inflammatory disease, which has a significant impact on patients’ health‐related quality of life. Although several existing psoriasis treatments are efficacious and well tolerated in many patients, some patients require treatment switching, and a proportion of patients remain untreated or undertreated. Potential challenges to the use of existing therapies include safety issues and limited efficacy in some patients with conventional oral psoriasis treatments, inconvenience of topical treatments and the requirement for parenteral administration of biologics.
What does this study add? Consistent efficacy and a safety profile consistent with that seen in rheumatoid arthritis, psoriatic arthritis and ulcerative colitis were demonstrated for oral tofacitinib in patients with moderate‐to‐severe psoriasis. Tofacitinib has a benefit–risk profile in patients with moderate‐to‐severe psoriasis that is consistent with that of other systemic psoriasis treatments.

Abstract
IL-6 is implicated in the development and progression of autoimmune diseases in part by influencing CD4 T cell lineage and regulation. Elevated IL-6 levels drive inflammation in a wide range of autoimmune diseases, some of which are also characterized by enhanced T cell responses to IL-6. Notably, the impact of IL-6 on inflammation is contextual in nature and dependent on the cell type, cytokine milieu and tissue. Targeting the IL-6/IL-6R axis in humans has been shown to successfully ameliorate a subset of autoimmune conditions. In this review, we discuss recent studies investigating how IL-6 regulates the CD4 T cell response in the context of autoimmune disease and highlight how blocking different aspects of the IL-6 pathway is advantageous in the treatment of disease.

Abstract
PURPOSE OF REVIEW Biologics and small molecules are key therapeutic options in the treatment of chronic immunologic and allergic skin conditions. By directly targeting innate and inflammatory responses within the skin, including pro-inflammatory cytokines and cellular signaling pathways, these new agents have the potential to counteract the inflammatory cascade responsible for various conditions, including psoriasis and atopic dermatitis. Over the past decade, groundbreaking research identifying key cytokines and receptors involved in the pathogenesis of these diseases has allowed for the development of highly efficacious biologics and small molecules that are associated with unprecedented rates of skin clearance and favorable adverse event profiles. RECENT FINDINGS This narrative review evaluates new and upcoming biologic and small molecule agents for the treatment of two allergic/immunologic skin diseases-atopic dermatitis and psoriasis. Numerous small molecules and biologics targeting TNF-α, IL-12/23, IL-17 and IL-17R, and IL-23 are commercially available for the treatment of psoriasis, and newer agents are in various stages of development. Currently, dupilumab, a monoclonal antibody that blocks IL-4R∝, is the only approved biologic for atopic dermatitis. Antibodies targeting IL-13 and IL-31 and small molecules that inhibit Janus kinase and pruritus-mediating receptors are currently being studied in clinical trials. Further investigations into the pathophysiology of atopic dermatitis will likely yield additional therapeutic options in the future. This article reviews recent literature on small molecules and biologics for the treatment of atopic dermatitis and psoriasis.

Abstract
Nowadays, it is well established a link between psoriasis and cardiovascular (CV) diseases. A series of different overlapping mechanisms including inflammation, homeostasis dysregulation, and genetic susceptibility are thought to underlie this association. Advances in understanding the molecular patterns involved in the complex scenario of psoriasis have highlighted a tight correlation with atherosclerosis. Indeed, common profiles are shared in term of inflammatory cytokines and cell types. In the last decade, the management of psoriasis patients has been revolutionized with the introduction of biological therapies, such as tumor necrosis factor-alpha (TNF-α), interleukin (IL)-12/23, and IL-17 inhibitors. In clinical setting, the effectiveness of these therapies as well as the incidence of CV events is related to the type of biologics. In particular, anti-TNF-α agents seem to reduce these events in psoriasis patients whereas anti-IL-12/23 agents related CV events reduction still remain to clarify. It has to be taken into account that IL-12/23 inhibitors have a shorter post-marketing surveillance period. An even more restricted observational time is available for anti-IL-17 agents. IL-17 is associated with psoriasis, vascular disease, and inflammation. However, IL-17 role in atherosclerosis is still debated, exerting both pro-atherogenic and anti-atherogenic effects depending on the specific context. In this review, we will discuss the differences between the onset of CV events in psoriasis patients, referred to specific biological therapy and the underlying immunological mechanism. Given the development of new therapeutic strategies, the investigation of these inhibitors impact on heart failure outcome is extremely important.

Abstract
There is increasing use of head-to-head clinical trials in dermatology when establishing the efficacy of a new treatment. Active comparator trials (ACTs) can be classified into three distinct study trial designs: non-inferiority, equivalence and superiority. A better understanding of the statistical parameters, such as acceptable treatment differences (also known as the margin or delta), is necessary to properly design and interpret findings of active comparator trials (ACTs) in the field of dermatology. Therefore, the objective of this study was to summarize the maximum acceptable treatment differences in clinical trials that examine the efficacy of an oral or biologic psoriasis therapy with an active comparator. We conducted a systematic search using MEDLINE, Scopus, EMBASE, Cochrane Central Register of Controlled Trials, LILACS, Web of Science and ClinicalTrials.gov from inception to 31 August 2017. All ACTs with adult participants that had a primary outcome of the Psoriasis Area and Severity Index score were included. Bibliographies of articles were further reviewed. Two investigators independently assessed for article inclusion and separately completed data extraction of predefined data points. When there was a disagreement, a third investigator was consulted. Of the 49 ACTs included, there were 13 superiority, eight non-inferiority and seven equivalence trials. Another 21 studies had inadequate information for classification. All of the non-inferiority trials reported the margin, one of the superiority and six of the equivalence trials stated the treatment difference explicitly. For superiority trials, acceptable treatment differences ranged from 14% to 20%. The non-inferiority studies reported lower bound margins ranging from -20% to -10%. The equivalence trials reported upper and lower bound margins ranging from ±12.5% to ±18%. The results demonstrate the need for harmonization in the conduct of dermatological clinical trials and in the approaches of reporting research parameters.

Abstract
Signal transducer and activator of transcription 3 (STAT3) is constitutively activated in psoriatic skin inflammation and acts as a key player in the pathogenesis and progression of this autoimmune disease. Although numerous inhibitors that intervene in STAT3-associated pathways have been tested, an effective, highly specific inhibitor of STAT3 has yet to be identified. Here, we evaluated the in vitro and in vivo biological activity and therapeutic efficacy of a high-affinity peptide specific for STAT3 (APTstat3) after topical treatment via intradermal and transcutaneous delivery. Using a preclinical model of psoriasis, we show that intradermal injection of APTstat3 tagged with a 9-arginine cell-penetrating peptide (APTstat3-9R) reduced disease progression and modulated psoriasis-related cytokine signaling through inhibition of STAT3 phosphorylation. Furthermore, by complexing APTstat3-9R with specific lipid formulations led to formation of discoidal lipid nanoparticles (DLNPs), we were able to achieve efficient skin penetration of the STAT3-inhibiting peptide after transcutaneous administration, thereby effectively inhibiting psoriatic skin inflammation. Collectively, these findings suggest that DLNP-assisted transcutaneous delivery of a STAT3-inhibiting peptide could be a promising strategy for treating psoriatic skin inflammation without causing adverse systemic events. Moreover, the DLNP system could be used for transdermal delivery of other therapeutic peptides.

Abstract
In this era, it is axiomatic that cytokines have critical roles in cellular development and differentiation, immune homeostasis, and host defense. Equally, dysregulation of cytokines is known to contribute to diverse inflammatory and immune-mediated disorders. In fact, the past 20 years have witnessed the rapid translation of basic discoveries in cytokine biology to multiple successful biological agents (mAbs and recombinant fusion proteins) that target cytokines. These targeted therapies have not only fundamentally changed the face of multiple immune-mediated diseases but have also unequivocally established the role of specific cytokines in human disease; cytokine biologists have many times over provided remarkable basic advances with direct clinical benefit. Numerous cytokines rely on the JAK-STAT pathway for signaling, and new, safe, and effective small molecule inhibitors have been developed for a range of disorders. In this review, we will briefly summarize basic discoveries in cytokine signaling and briefly comment on some major unresolved issues. We will review clinical data pertaining to the first generation of JAK inhibitors and their clinical indications, discuss additional opportunities for targeting this pathway, and lay out some of the challenges that lie ahead.

Abstract
Psoriasis is a chronic, immune mediated disorder affecting approximately 2% of the population. Even in our days, patients with psoriasis are confronted with stigmatization and social rejection. As a result, their quality of life is significantly impaired. Biological therapies have revolutionized the treatment of moderate to severe psoriasis. The aim of this paper is to look over the most important biological therapies available for the management of plaque-type psoriasis.

Abstract
Psoriasis is a chronic inflammatory skin condition affecting diverse racial/ethnic groups throughout the world. Large population-based studies suggest that psoriasis occurs most often in individuals of European ancestry, followed by black and Hispanic individuals, although the true prevalence of psoriasis in non-white individuals is likely underestimated. Despite similarities in psoriasis between ethnic groups, there are notable differences in the presentation, quality-of-life impact, and treatment of psoriasis with important implications for the management of non-white individuals. Overall, heterogeneity in psoriasis susceptibility alleles, in combination with cultural and socioeconomic factors, may explain these differences. In this article, we review the epidemiology, clinical presentation, genetic polymorphisms, quality-of-life impact, and treatment nuances of psoriasis in patients with skin of color.

Abstract
Over the past 15 years, the spectrum of systemic antipsoriatic treatments has dramatically expanded. Until the end of the last millennium, systemic therapy had been restricted to four oral agents: methotrexate, cyclosporine, acitretin, and fumaric acid esters. Today, there are additionally seven biologics and one new oral antipsoriatic drug, as well as the first available biosimilars. Six more biologics with novel target structures and at least four biosimilars are currently being developed (phase III). This progress has been based on new insights into the pathogenesis of psoriasis, in which tumor necrosis factor and especially Th17 immune responses with their associated cytokines interleukin 23 and 17 play a key role. The development of new-generation biologics as well as immunomodulatory small molecules can be attributed to these pathophysiological findings. Phosphodiesterase 4 inhibitors, dimethyl fumarate, and Janus kinase inhibitors all interact with Th17 immune responses. Some of these drugs are in advanced clinical development and are also beneficial in psoriatic arthritis. Today, psoriasis and psoriatic arthritis therefore rank among the most readily treatable inflammatory autoimmune disorders. Dermatology is increasingly becoming a specialty of modern targeted immunotherapies.

Abstract
The IL-6/JAK/STAT3 pathway is aberrantly hyperactivated in many types of cancer, and such hyperactivation is generally associated with a poor clinical prognosis. In the tumour microenvironment, IL-6/JAK/STAT3 signalling acts to drive the proliferation, survival, invasiveness, and metastasis of tumour cells, while strongly suppressing the antitumour immune response. Thus, treatments that target the IL-6/JAK/STAT3 pathway in patients with cancer are poised to provide therapeutic benefit by directly inhibiting tumour cell growth and by stimulating antitumour immunity. Agents targeting IL-6, the IL-6 receptor, or JAKs have already received FDA approval for the treatment of inflammatory conditions or myeloproliferative neoplasms and for the management of certain adverse effects of chimeric antigen receptor T cells, and are being further evaluated in patients with haematopoietic malignancies and in those with solid tumours. Novel inhibitors of the IL-6/JAK/STAT3 pathway, including STAT3-selective inhibitors, are currently in development. Herein, we review the role of IL-6/JAK/STAT3 signalling in the tumour microenvironment and the status of preclinical and clinical investigations of agents targeting this pathway. We also discuss the potential of combining IL-6/JAK/STAT3 inhibitors with currently approved therapeutic agents directed against immune-checkpoint inhibitors.

Abstract
Generation of skin distribution profiles and reliable determination of drug molecule concentration in the target region are crucial during the development process of topical products for treatment of skin diseases like psoriasis and atopic dermatitis. Imaging techniques like mass spectrometric imaging (MSI) offer sufficient spatial resolution to generate meaningful distribution profiles of a drug molecule across a skin section. In this study, we use matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) to generate quantitative skin distribution profiles based on tissue extinction coefficient (TEC) determinations of four different molecules in cross sections of human skin explants after topical administration. The four drug molecules: roflumilast, tofacitinib, ruxolitinib, and LEO 29102 have different physicochemical properties. In addition, tofacitinib was administrated in two different formulations. The study reveals that with MALDI-MSI, we were able to observe differences in penetration profiles for both the four drug molecules and the two formulations and thereby demonstrate its applicability as a screening tool when developing a topical drug product. Furthermore, the study reveals that the sensitivity of the MALDI-MSI techniques appears to be inversely correlated to the drug molecules' ability to bind to the surrounding tissues, which can be estimated by their Log D values.
