Project description:Risankizumab (Skyrizi®; risankizumab-rzaa) is a humanized immunoglobulin (Ig) G1 monoclonal antibody that specifically targets the p19 subunit of interleukin (IL)-23, thereby inhibiting IL-23-dependent cell signaling. Subcutaneous risankizumab is approved for the treatment of adults with moderate to severe plaque psoriasis who are candidates for systemic therapy (in the EU), those who are candidates for systemic therapy or phototherapy (in the USA) and those who have an inadequate response to conventional therapies (in Japan). In pivotal phase III trials (UltIMMa-1, UltIMMa-2, IMMvent and IMMhance), risankizumab was more effective than placebo, ustekinumab and adalimumab with regard to the proportion of patients achieving ≥ 90% improvement from baseline in Psoriasis Area and Severity Index score (PASI 90) and a static Physician's Global Assessment score of 0 or 1 at week 16, with these benefits maintained over the longer term. In supportive head-to-head trials, risankizumab was also superior to secukinumab and fumaric acid esters in terms of PASI 90 response rate. In an ongoing open-label extension study (LIMMitless), risankizumab was associated with durable and improved efficacy after switching from ustekinumab or adalimumab, as well as durable maintenance of efficacy through > 2.5 years of continuous exposure. Treatment with risankizumab improved health-related quality of life and was generally well tolerated, both in the short- and longer-term. In conclusion, risankizumab represents a useful new treatment option for patients with moderate to severe plaque psoriasis.

Project description:Subcutaneous secukinumab (Cosentyx®) is a recombinant, fully human, immunoglobulin (Ig) G1κ monoclonal antibody targeted against interleukin (IL)-17A, a proinflammatory cytokine involved in the pathogenesis of psoriasis. Secukinumab is approved in the EU and the USA for the treatment of moderate to severe plaque psoriasis in pediatric patients aged ≥ 6 years. In pivotal phase III trials in pediatric patients aged 6 to < 18 years, both low (75-150 mg) and high (75-300 mg) doses of secukinumab were significantly better than placebo and numerically better than etanercept at week 12 in terms of the proportion of patients achieving ≥ 75% improvement from baseline in Psoriasis Area and Severity Index and significantly better than placebo and etanercept in terms of the proportion of patients achieving an Investigator's Global Assessment score of 0 or 1. The clinical efficacy of secukinumab observed during the first 12 weeks of treatment was maintained over the longer term. Treatment with secukinumab improved health-related quality of life and was generally well tolerated. In conclusion, secukinumab represents a valuable new addition to the limited treatment options available for children and adolescents with moderate to severe plaque psoriasis.

Project description:Brodalumab is a fully human monoclonal antibody targeting the IL-17 receptor A leading to an inhibition of the biological effect of IL-17A, IL-17F, IL-17A/F heterodimer, IL-17C and IL-17E isoforms. It has shown to be efficacious in the treatment of moderate to severe plaque psoriasis (210 mg administered subcutaneously at weeks 0, 1 and 2 followed by 210 mg every 2 weeks [Q2W+1]). A population pharmacokinetic model based on psoriasis patients only from six clinical trials was developed to describe the pharmacokinetics and identify sources of variability. In patients with psoriasis, Brodalumab exhibits non-linear pharmacokinetics due to target-mediated drug disposition resulting in concentration-dependent clearance. The pharmacokinetics was best described by a two-compartment model with linear absorption and combined linear and Michaelis-Menten elimination. The subcutaneous bioavailability of Brodalumab was 55%, absorption rate was 0.30 day-1 , and body-weight was found to affect the volume of distribution and clearance. For a reference patient with plaque psoriasis (body-weight of 90 kg), the estimates were 0.16 L/d for linear serum clearance, 6.1 mg/d for the maximum non-linear clearance rate, and 4.7 and 2.4 L for central and peripheral volume of distribution, respectively. For the approved dosing regimen, time to maximum concentration was 4 days and 90% of steady-state was achieved after 10 weeks for a reference patient. Following last dose at steady-state, 90% of the population of reference patients will reach serum concentrations below lower limit of quantification after 45 days.

Project description:IntroductionPsoriasis is an immune-mediated, chronic, inflammatory disease, which has a substantial humanistic and economic burden. This study aimed to assess the impact of this disease on health-related quality of life (HRQoL), work productivity, and direct and indirect costs from a societal perspective among Brazilian patients.MethodsThis is a cross-sectional, observational, multicenter study, enrolling patients with moderate to severe plaque psoriasis according to physician evaluation. Data collection was performed from December 2015 to November 2016 through face-to-face interviews using a structured questionnaire and five standardized patient-reported outcomes instruments. Direct costs were estimated by multiplying the amount of resources used (12-month recall period) by the corresponding unit cost. Indirect costs were grouped in two time horizons: annual costs (income reduction and absenteeism) and lifetime costs (demission and early retirement).ResultsA total of 188 patients with moderate to severe plaque psoriasis were included, with mean age of 48.0 (SD 13.1). "Anxiety and depression" and "pain and discomfort" were the most impaired dimensions, according to the EuroQol Five-Dimension-Three-Level (EQ-5D-3L). The highest effect was found for "symptoms and feelings" [mean (SD) 2.4 (1.7)] Dermatology Life Quality Index (DLQI) subscale. Psoriatic arthritis (PsA) presence and biologic-naïve status were associated with worse HRQoL. Presenteeism was more frequent than absenteeism, according to the Work Productivity and Activity Impairment questionnaire-General Health (WPAI-GH) [17.4% vs. 6.3%], while physical demands and time management were the most affected Work Limitations Questionnaire (WLQ) subscales [means (SD) 23.5 (28.5) and 17.7 (24.9), respectively]. The estimated annual cost per patient was USD 4034. Direct medical costs accounted for 87.7% of this estimate, direct non-medical costs for 2.4%, and indirect costs for 9.9%.ConclusionsResults evidenced that moderate to severe plaque psoriasis imposes substantial costs to society. Our data showed that this disease negatively affects both work productivity and HRQoL of Brazilian patients. Subgroups with PsA and biologic-naïve patients presented lower HRQoL, showing the impact of this comorbidity and the relevance of biologics in psoriasis treatment.FundingNovartis Biociências S.A.

Project description:IntroductionDeucravacitinib, an oral tyrosine kinase 2 (TYK2) inhibitor, is approved in the United States to treat adults with moderate-to-severe plaque psoriasis (PsO). This study compared the long-term efficacy of deucravacitinib and adalimumab using results from long-term extension (LTE) trials.MethodsOpen-label LTE trials were identified for an indirect treatment comparison (deucravacitinib: POETYK PSO-LTE [NCT04036435]; adalimumab: REVEAL extension [NCT00195676]). To ensure study design comparability, patients initially randomized to placebo and switched to deucravacitinib or adalimumab after week 16 were compared. The primary outcome was an ≥ 75% reduction in Psoriasis Area and Severity Index score (PASI 75) at week 112 postrandomization. Secondary outcomes were PASI 75 at week 52 and an ≥ 90% reduction in PASI score (PASI 90) at weeks 52 and 112. Missing PASI data were imputed. A matching-adjusted indirect comparison was conducted; individual patient-level data from POETYK PSO-LTE were reweighted to balance baseline characteristics with those from the REVEAL extension.ResultsBefore reweighting, on average, patients in the POETYK PSO-LTE (N = 329) versus the REVEAL (N = 345) extension were older, had a lower body weight, received more prior systemic treatments, and had higher baseline PASI scores and week 16 placebo PASI 75 and PASI 90 response rates. Following reweighting, adjusted week 112 PASI 75 response rates were significantly higher for deucravacitinib versus adalimumab (67.2% vs. 54.0%; mean difference [95% CI], 13.2 [4.0-22.5] percentage points). Deucravacitinib had a numerically higher adjusted week 112 PASI 90 response rate (41.3% vs. 34.0%; mean difference [95% CI], 7.3 [-2.0 to 16.7] percentage points). The treatments had similar week 52 adjusted PASI 75 and PASI 90 response rates.ConclusionIn this interim analysis, adults with moderate to severe PsO had higher long-term response rates at 2 years when treated with deucravacitinib versus adalimumab. Deucravacitinib response rates remained stable whereas adalimumab response rates declined in year 2.

Project description:New biologic agents targeting interleukin (IL)23/T-helper17 axis, such as tildrakizumab, have been developed for the treatment of plaque psoriasis. To analyze the efficacy and safety of tildrakizumab in a real life setting of patients affected by moderate-to-severe psoriasis over a 28-week treatment period. A multicentric retrospective study was conducted in patients who initiated tildrakizumab between February 2020 and March 2021. Psoriasis Area and Severity Index-PASI was measured at baseline and after 4, 16 and 28 weeks. The percentage change in PASI value from baseline to the considered time-points, proportion of patients with absolute PASI <3 at week 28 and the percentages of achieving a PASI75 or PASI90 response were assessed. Data about potential safety issues and adverse events (AEs) were collected. Statistical analysis were performed for establish clinical efficacy and for variables predicting clinical response. Fifty nine patients with psoriasis were included. Overall mean PASI percentage reduction was of 88% from baseline to week 28 and 47 out of 59 patients (79.7%) at week 28 had an absolute PASI <3. PASI75 and PASI90 responses at week 28 were achieved by 48 (81.40%) patients and 38 (64.4.0%) patients, respectively. No substantial associations between gender, body mass index - BMI, PASI at baseline and prior exposition to biological therapies and the efficacy endpoints were retrieved. No serious safety issues or discontinuations related to adverse events were reported. In our real-life study, tildrakizumab showed high efficacy and a favorable safety profile, regardless of patient- and disease-related factors.

Project description:Dimethyl fumarate (DMF) is an oral systemic agent approved for the treatment of moderate-to-severe psoriasis vulgaris. It has a favourable tolerability profile, but it is associated with a high incidence of mild and reversible adverse events. The aim of the article is to describe a clinical experience aimed at increasing tolerability. A group of patients was treated with DMF with a titration schedule, according to clinical practice, although a personalization of the step-up timing was allowed. The highest dose was the minimal effective dose or the maximal tolerated doses. DMF treatment was effective in reducing the disease severity and improving the quality of life. DMF was well tolerated as only mild, mainly gastrointestinal, adverse events occurred in these patients. In addition, the up-titration schedule seemed to provide a reduced incidence of adverse events compared with the fixed dose. Our experience suggested that the recommended up-titration schedule of DMF, adjusted and personalized according to patient needs and physician opinion, provided a relevant clinical benefit and was well tolerated.

Project description:Psoriasis is a chronic immune-mediated disease involving complex interaction of T cells and keratinocytes. The comprehensive pathogenesis of psoriasis is not fully understood but the IL-23/Th17 axis is a central pathway in driving disease development. Guselkumab is the first treatment of moderate-to-severe psoriasis that specifically targets the p19 subunit of IL-23. The benefit of guselkumab has been established by a number of clinical trials including demonstration of greater long-term efficacy in recent comparator trials. This review addresses the results of head-to-head trials (ECLIPSE, IXORA-R, and POLARIS) that compared guselkumab to secukinumab, ixekizumab, and fumaric acid esters. The previously demonstrated long-term efficacy of guselkumab has been corroborated by many recently published studies. The effective and safe profile, convenient dosing, and improved quality of life in patients make gulselkumab a viable first-line treatment option for moderate-to-severe psoriasis.

Project description:IntroductionPsoriasis is a chronic, immune-mediated skin condition with significant detriments to physical/mental health. While systemic therapies are available for the treatment of moderate-to-severe psoriasis, patients can experience therapeutic failure, loss of efficacy, or medical contraindications that require other therapeutic options.ObjectiveWith the recent approval of deucravacitinib, a first-in-class TYK2 small molecule inhibitor administered orally for psoriasis patients, we reviewed data from randomized controlled trials (RCTs) to synthesize its clinical utility. To our knowledge, this is the first systematic review and meta-analysis of deucravacitinib comparing its clinical efficacy to placebo in psoriasis.MethodsA literature search was conducted in PubMed (MEDLINE), Embase, and the Cochrane Central Register of Controlled Trials to identify RCTs studying deucravacitinib in human patients with moderate-to-severe psoriasis.ResultsOne placebo-controlled Phase II RCT and two placebo-controlled/active-comparator Phase III RCTs were included for review. Patients (N=1953) treated with deucravacitinib 6 mg daily showed marked improvement in disease severity (Psoriasis Area and Severity Index (PASI), static Physician Global Assessment (sPGA) and quality-of-life outcomes compared to patients administered comparator (apremilast) and placebo. Clinical improvement given deucravacitinib was noted for scalp psoriasis but not fingernail psoriasis. Meta-analysis (deucravacitinib, n=888; placebo, n=466) comparing rates of clearance (sPGA 0/1) demonstrated superior efficacy of deucravacitinib compared to placebo (odds ratio, 12.87; 95% confidence interval, 8.97-18.48; χ2=4.08, I2=51%). Deucravacitinib was well-tolerated, with similar rate of occurrence and type of adverse events reported among patients treated with placebo or apremilast at Week 12-16. No cardiovascular events, serious infections, or lab abnormalities were noted.ConclusionDeucravacitinib possesses good efficacy, with no report of safety concerns associated with prior JAK inhibitors used for psoriasis. Meta-analysis demonstrated deucravacitinib's superiority compared to placebo, indicating its promising clinical utility. Further studies are needed to observe long-term safety and efficacy, and to compare deucravacitinib to existing treatments.
