Project description:During the 28th Congress of the European Academy of Dermatology and Venereology (EADV) held in Madrid in October 2019, an industry hub was dedicated to the long-term management of psoriasis. Psoriasis is a systemic inflammatory disease primarily involving the skin that affects up to 4% of the European population, the majority of whom present with chronic plaque psoriasis. Topical therapies are well established in the first-line treatment of psoriatic plaque flares. Nevertheless, as psoriasis is a chronic disease, long-term control should be considered. The aim of the session was to provide expert opinion on the benefit of long-term maintenance therapy in chronic plaque psoriasis and introduce the concept of pro-active management to decrease the number of relapses and improve patient quality of life. The current guidelines and recommendations were reviewed, as well as the available data on published clinical trials. There is still an important role for topical therapy in psoriasis and current recommendations suggest a maintenance regimen for psoriasis. Adherence optimization and proactive management of relapse can be key factors for obtaining clinical outcomes in topical long-term therapy. Calcipotriol/betamethasone dipropionate foam is the only topical formulation with long-term data as a twice-weekly proactive treatment approach for up to 52 weeks for chronic plaque psoriasis.

Project description:BackgroundTranscription factor retinoic acid-related orphan receptor 2 (RORC2/ROR?T) mediates interleukin (IL)-17A and IL-17F expression. IL-17A plays a central role in the pathogenesis of several inflammatory disorders, including psoriasis. The RORC2 inhibitor PF-06763809 has been hypothesized to inhibit IL-17A production in T-helper 17 (Th17) cells, thereby reducing psoriasis symptoms.AimTo assess the safety, tolerability and effect on skin infiltrate thickness of PF-06763809 in participants with mild/moderate chronic plaque psoriasis.MethodsThis was a randomized, double-blind, first-in-human study (trial registration: ClinicalTrials.gov NCT03469336). Participants received each of the following six treatments once daily for 18 days: three topical doses (2.3%, 0.8%, 0.23%) of PF-06763809, a vehicle and two active comparators (betamethasone and calcipotriol). Primary endpoints included change from baseline in psoriatic skin infiltrate thickness [echo-poor band (EPB) on ultrasonography] at Day 19, and safety. Change in psoriasis-associated gene expression (Day 19), evaluated by real-time reverse transcription PCR of skin biopsies, was an exploratory endpoint.ResultsIn total, 17 participants completed the study. Change from baseline in the EPB on Day 19 for all three doses of PF-06763809 was not significantly different from that of vehicle (P > 0.05). A significant reduction in EPB from baseline was observed with betamethasone on Day 19 relative to all other treatments (P < 0.0001). Treatment-related adverse events were mild/moderate. There were no significant differences in gene expression on Day 19 between vehicle and PF-06763809-treated skin lesions.ConclusionUsing a psoriasis plaque test design, PF-06763809 was found to be well tolerated with an acceptable safety profile in participants with psoriasis, but without reduction in skin infiltrate thickness or disease biomarkers.

Project description:Tofacitinib (CP-690,550) is a novel Janus kinase inhibitor in development as an oral formulation for the treatment of several inflammatory diseases including psoriasis.This phase 2a study aimed to assess the efficacy, systemic safety, local tolerability and systemic pharmacokinetics of topical tofacitinib in mild-to-moderate plaque psoriasis.Two tofacitinib ointment formulations were evaluated in this multicentre, double-blind, vehicle-controlled trial (NCT01246583). Seventy-one patients were randomized 2 : 1 : 2 : 1 to 2% tofacitinib ointment 1, vehicle 1, 2% tofacitinib ointment 2 and vehicle 2, each administered twice daily for 4 weeks to a single fixed 300 cm(2) treatment area containing a target plaque with or without one or more nontarget plaques and normal skin.The primary endpoint of percentage change from baseline in the Target Plaque Severity Score at week 4 demonstrated statistically significant improvement for ointment 1 [least squares mean (LSM) -54.4%] vs. vehicle 1 (LSM -41.5%), but not ointment 2 (LSM -24.2%) vs. vehicle 2 (LSM -17.2%). Secondary endpoints (target plaque area and Itch Severity Item) improved similarly for tofacitinib ointment vs. corresponding vehicle. Adverse event (AE) occurrence was similar across treatment groups. All AEs were mild or moderate and none were serious or led to subject discontinuation. One application-site AE (erythema) was reported. Tofacitinib mean systemic exposure was minimal and was greater for ointment 1 than for ointment 2.Tofacitinib ointment 1 was well tolerated and efficacious compared with vehicle for the treatment of plaque psoriasis. Further study of topical tofacitinib for psoriasis treatment is warranted.

Project description:Psoriasis affects 1-3% of the population, in some people causing changes to the nails and joints in addition to skin lesions.We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of systemic drug treatments, topical drug treatments, and non-drug treatments (other than ultraviolet light) for chronic plaque psoriasis? What are the effects of ultraviolet light treatments for chronic plaque psoriasis? What are the effects of combined treatment with drugs plus ultraviolet light on chronic plaque psoriasis? What are the effects of combined systemic plus topical drug treatments for chronic plaque psoriasis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2007 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).We found 122 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, adding calcipotriol (topical) to psoralen plus ultraviolet light A or ultraviolet light B, adding oral retinoids to psoralen plus ultraviolet A (PUVA), alefacept, balneotherapy, ciclosporin, dithranol, T cell-targeted therapies, cytokine blocking agents, emollients (alone or plus ultraviolet light B), etanercept, fish oil supplementation, fumaric acid derivatives, Goeckerman treatment, heliotherapy, infliximab, Ingram regimen, keratolytics (salicylic acid, urea), leflunomide, methotrexate, oral pimecrolimus, phototherapy plus balneotherapy, psoralen plus ultraviolet A, psychotherapy, oral retinoids (alone or with ultraviolet light B), systemic drug treatments plus topical vitamin D derivatives, tars, tazarotene, topical corticosteroids (alone or plus oral retinoids), topical Vitamin D derivatives, ultraviolet light A, and ultraviolet light B.

Project description:IntroductionDose escalation and reduction of biologic treatments are frequent in clinical practice. The aim of this systematic review is to summarise evidence on dose adjustment of biologic treatments for moderate-to-severe plaque psoriasis in the real-world.MethodsA systematic review of real-world evidence on dose adjustment of biologics for plaque psoriasis was performed. Searches were conducted in BIOSIS Previews®, Embase®, International Pharmaceutical Abstracts, MEDLINE®, and SciSearch® in March 2020. Real-world studies that reported biologic dose adjustment for moderate-to-severe plaque psoriasis were included.ResultsThe search identified 162 papers, and 20 studies with 30,912 patients were included from 2014 to 2020. More studies reported on dose escalation than dose reduction. For adalimumab, 3-54% of patients had dose reduction while 0-37% had dose escalation. For infliximab, only two studies reported a dose reduction, with rates of 22-29%, while dose escalation rates varied from 14 to 67%. Dose reduction rates of 5-49% were reported for etanercept while 0-55% of patients had doses escalated. For ustekinumab, dose escalation and reduction rates ranged from 3 to 37% and 7 to 42%, respectively. Two studies reported on dose adjustment for secukinumab; in one 52% of patients initiated on 150 mg instead of the recommended 300 mg, while another reported no dose increase.ConclusionsDose adjustment of biologics for psoriasis is common, with escalation more frequently reported than reduction. Dose escalation may have economic and safety consequences, while dose reduction may impact efficacy. These aspects are important to consider when making decisions on treatment dosing.

Project description:AIMS:The use of biologic therapy has increased over the past decade well beyond primary autoimmune diseases. Indeed, a recent trial using an anti-IL-1beta antibody reduced second myocardial infarction (MI) in those who have had MI. Psoriasis is a chronic inflammatory disease often treated with biologics when severe, is associated with increased risk of MI, in part driven by high-risk coronary plaque phenotypes by coronary computed tomography angiography (CCTA). We hypothesized that we would observe a reduction in inflammatory-driven phenotypes of coronary plaque, including non-calcified coronary plaque burden and lipid-rich necrotic core in those treated with biologic therapy after one-year compared with non-biologic therapy. METHODS AND RESULTS:In a prospective, observational study, 290 participants were recruited from 1 January 2013 through 31 October 2018 with 215 completing one-year follow-up. Of the 238, 121 consecutive participants who were biologic treatment naïve at baseline were included. A blinded reader (blinded to patient demographics, visit and treatment) quantified total coronary plaque burden and plaque subcomponents (calcified and non-calcified) in the three main coronary vessels >2 mm using dedicated software (QAngio, Medis, Netherlands). Psoriasis patients were middle-aged [mean (standard deviation) age, 50.5 (12.1) years], mostly male (n = 70, 58%) with low cardiovascular risk by Framingham score [median (interquartile range, IQR), 3 (1-6)] and had moderate to severe skin disease at baseline [median (IQR) Psoriasis Area Severity Index, PASI, 8.6 (5.3-14.0)]. Biologic therapy was associated with a 6% reduction in non-calcified plaque burden (P = 0.005) reduction in necrotic core (P = 0.03), with no effect on fibrous burden (P = 0.71). Decrease in non-calcified plaque burden in the biologic treated group was significant compared with slow plaque progression in non-biologic treated (Δ, -0.07 mm2 vs. 0.06 mm2; P = 0.02) and associated with biologic treatment beyond adjustment for traditional cardiovascular risk factors (β = 0.20, P = 0.02). CONCLUSION:In this observational study, we demonstrate that biologic therapy in severe psoriasis was associated with favourable modulation of coronary plaque indices by CCTA. These findings highlight the importance of systemic inflammation in coronary artery disease and support the conduct of larger, randomized trials.

Project description:ObjectivesWhile off-label dosing of biologic treatments may be necessary in selected psoriasis patients, no systematic review exists to date that synthesizes the efficacy and safety of these off-label dosing regimens. The aim of this systematic review is to evaluate efficacy and safety of off-label dosing regimens (dose escalation, dose reduction, and interrupted treatment) with etanercept, adalimumab, infliximab, ustekinumab, and alefacept for psoriasis treatment.Data sources and study selectionWe searched OVID Medline from January 1, 1990 through August 1, 2011 for prospective clinical trials that studied biologic therapy for psoriasis treatment in adults. Individual articles were screened for studies that examined escalated, reduced, or interrupted therapy with etanercept, adalimumab, infliximab, ustekinumab, or alefacept.Data synthesisA total of 23 articles with 12,617 patients matched the inclusion and exclusion criteria for the systematic review. Data were examined for primary and secondary efficacy outcomes and adverse events including infections, malignancies, cardiovascular events, and anti-drug antibodies. The preponderance of data suggests that continuous treatment with anti-TNF agents and anti-IL12/23 agent was necessary for maintenance of disease control. Among non-responders, dose escalation with etanercept, adalimumab, ustekinumab, and alefacept typically resulted in greater efficacy than standard dosing. Dose reduction with etanercept and alefacept resulted in reduced efficacy. Withdrawal of the examined biologics led to an increase in disease activity; efficacy from retreatment did not result in equivalent initial response rates for most biologics. Safety data on off-label dosing regimens are limited.ConclusionDose escalation in non-responders generally resulted in increased efficacy in the examined biologics used to treat moderate-to-severe psoriasis. Continuous treatment with anti-TNF agents and anti-IL12/23 agent results in superior efficacy over interrupted therapy. The decision to use off-label dosing needs to account for both benefits and risks and be individualized to patients' disease severity, quality of life, and existence of comorbidities.

Project description:Psoriasis is a chronic inflammatory skin disease affecting about 1-3% of the general population. Moderate-to-severe psoriasis is commonly associated with various comorbidities, including psoriatic arthritis (PsA) and cardio-metabolic disorders such as obesity, hypertension, diabetes, and metabolic syndrome. There is increasing recognition that systemic inflammation accompanies severe skin disease. Abnormal innate and adaptive immune responses in the skin are involved in pathogenesis. The cytokine interleukin (IL)-17A is produced by T helper 17 (Th17) cells, neutrophils, mast cells, and T cytotoxic 17 cells. IL-17 plays a key role in host defense against extracellular bacteria and fungi. IL-17A acts on keratinocytes to increase expression of chemokines involved in recruiting myeloid dendritic cells, Th17 cells, and neutrophils to the lesion site. IL-17A also induces the production of antimicrobial peptides and pro-inflammatory cytokines that, in turn, may amplify and sustain immune responses in the skin. Blocking IL-17A improved psoriasis-like pathology in experimental models, and reduction in IL-17 signaling is part of the mechanism of action of tumor necrosis factor-α blockers. Three agents neutralizing IL-17 (i.e., secukinumab and ixekizumab) or antagonizing its receptor (i.e., brodalumab) are currently being tested for efficacy and safety in the treatment of plaque psoriasis and PsA. Secukinumab is a fully human IgG1 monoclonal antibody that selectively binds and neutralizes IL-17A whose efficacy in the therapy of chronic plaque psoriasis has been demonstrated in different phase II clinical trial. No new safety signals have emerged so far.

Project description:The development of several highly effective biologic drugs in the past decade has revolutionized the treatment of moderate-to-severe plaque psoriasis. With increased understanding of the immunopathogenesis of psoriasis, the emphasis has turned toward more specific targets for psoriasis drugs. Although the complex immunological pathway of psoriasis is not yet completely understood, current models emphasize the significant importance of interleukin (IL)-23 and IL-17. Several biologic drugs targeting these cytokines are now in various stages of drug development. Drugs targeting IL-23 include BI-655066, briakinumab, guselkumab, tildrakizumab, and ustekinumab. Drugs targeting IL-17 include brodalumab, ixekizumab, and secukinumab. While many of these have shown safety and good efficacy in clinical trials of moderate-to-severe plaque psoriasis, long-term safety is still to be established.

Project description:Psoriasis is an inflammatory and chronic skin disorder associated with physical and psychological burden impairing patients' quality of life. In the last decade, biologic drugs have widely changed treatment of moderate-severe psoriasis and their number is increasing overtime. To early identify expected/unexpected adverse events (AEs) with biologic treatments, pharmacovigilance programs are needed. We designed a post-marketing active pharmacovigilance program to monitor and analyse AEs and/or serious adverse events (SAEs) reports. All consecutive patients treated with one biologic drug during a two-years period and satisfying inclusion criteria have been enrolled in five Dermatology tertiary units. Demographic and clinical features of patients, type of treatment used, therapy discontinuation, failures, switch/swap to another biologic, and possible onset of AEs were collected. Overall, 512 patients with a diagnosis of psoriasis (286; 55.9%) or arthropathic psoriasis (226; 44.1%) have been enrolled. Eighty-two (16%) patients with AEs and 5 (1%) with SAEs have been identified. Further, 59 (11.5%) had a primary/secondary failure (mainly on infliximab and etanercept). The adverse events and SAEs were reported with golimumab (4/12), adalimumab (32/167), infliximab (9/48), etanercept (31/175) and ustekinumab (11/73), no adverse events have occurred with secukinumab (0/37). Infliximab and etanercept were significantly associated with primary/secondary failures, whereas no differences have been highlighted for AEs insurgence. On the other hand, ustekinumab seems to be associated with a low rate of AEs (p = 0.01) and no adverse events or failures have been reported with secukinumab (p = 0.04 and 0.03, respectively). Our study, even though limited by a small sample size and a brief follow-up period, provide useful data on widely used biologic drugs and their tolerability, discontinuation rate and the incurrence of severe adverse events. Further studies are necessary to include the recently approved biologic drugs and to increase the sample size for more detailed analysis.
