Background: With the increasing use of biological agents for the treatment of psoriasis, the numbers of patients with interstitial lung disease (ILD) associated with biologics have also increased. Many of these cases were associated with tumour necrosis factor (TNF)-α inhibitors, but cases associated with other families of biologics have also been reported in Japan., Aim: To analyse the background factors of patients who developed ILD, and to discuss better management of biological treatment., Method: We reviewed 246 patients with psoriasis who were treated with biological agents in our department to identify any pulmonary adverse events (AEs). Data on patients who developed ILD were extracted to analyse background factors, clinical type of psoriasis, time to onset of ILD, pre-existing ILD, smoking habit and prescribed drugs., Results: Pulmonary AEs were seen in 22 cases, of which 11 were diagnosed as drug-induced ILD. The causative drugs were mainly TNF-α inhibitors, accounting for eight cases (six treated with infliximab, two with adalimumab). The remaining three cases were associated with secukinumab, ustekinumab and ixekizumab (n = 1 each). Notably, these three cases also had a history of drug-induced ILD., Conclusion: Patients with a history of drug-induced ILD seem to be more susceptible to developing another ILD induced by biologics, even if treated with interleukin-17 inhibitors. Thorough screening of risk factors and evaluation for eligibility, and careful monitoring during treatment are the best solutions to avoid serious pulmonary AE. Early detection and precise diagnosis of pulmonary AEs, especially differentiation from infectious diseases, is essential for managing biological treatment., (© 2020 British Association of Dermatologists.)

Background & Aims: The efficacy of antibody-based therapeutics depends on their pharmacokinetics. The pharmacokinetic and exposure response profiles of ustekinumab, a monoclonal antibody against interleukin 12/interleukin 23, are known in patients with Crohn's disease, yet there are few data from patients with ulcerative colitis. We characterized ustekinumab's pharmacokinetics, exposure response, and optimal serum concentrations in patients with ulcerative colitis., Methods: We collected data from 2 phase 3 trials (1 induction and 1 maintenance), in which patients with moderate to severe ulcerative colitis received an intravenous induction dose of ustekinumab (130 mg, n = 320; or approximately 6 mg/kg, n = 322). Responders were assigned randomly to groups that received subcutaneous maintenance ustekinumab (90 mg) every 8 weeks (n = 176) or 12 weeks (n = 172), or placebo (n = 175). We evaluated the association between ustekinumab concentration and efficacy, serum based on clinical effects (Mayo score), histologic features, and inflammation (measurement of C-reactive protein, fecal calprotectin, and fecal lactoferrin), as well as safety (infections, serious infections, and serious adverse events), during induction and maintenance therapy. Optimal serum concentrations of ustekinumab were identified using receiver operating characteristic curve analyses., Results: In patients with ulcerative colitis, dose-proportional serum concentrations of ustekinumab, unaffected by prior biologic or concomitant immunomodulator therapy, reached steady state by the second maintenance dose; the median trough concentration for dosing every 8 weeks was approximately 3-fold that of dosing every 12 weeks. Serum concentrations were associated with clinical and histologic features of efficacy and normalization of inflammation markers. The week-8 concentration threshold for induction of response was 3.7 μg/mL. A steady-state trough serum concentration of 1.3 μg/mL or higher was associated with a higher rate of clinical remission compared with patients who had lower serum concentrations. Serum concentrations of ustekinumab were not associated with infections, serious infections, or serious adverse events., Conclusions: In an analysis of data from 2 phase 3 trials of patients with ulcerative colitis, we found that serum concentrations of ustekinumab were proportional to dose, unaffected by prior biologic or concomitant immunomodulator therapies, associated with clinical and histologic efficacy and markers of inflammation, and were not associated with safety events at doses evaluated. Ustekinumab pharmacokinetics are consistent between patients with Crohn's disease vs ulcerative colitis., (Copyright © 2020 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Objectives: The objectives of this study were to describe the demographic profile and baseline disease characteristics of patients with psoriatic arthritis (PsA) treated with either infliximab (IFX), subcutaneous golimumab (GLM) or ustekinumab (UST) treatment in Canadian routine care setting along with assessing long-term effectiveness and safety., Methods: Patients with PsA were enrolled into the Biologic Treatment Registry Across Canada registry (ClinicalTrials.gov Identifier: NCT00741793) from 2005 to 2017. The study visits occurred at study enrolment (baseline) and every 6 months thereafter. Effectiveness was assessed by changes in disease parameters (joint counts, Psoriasis Area Severity Index (PASI), Health Assessment Questionnaire, patient/physician global, minimal disease activity, enthesitis, dactylitis, erythrocyte sedimentation rate, C reactive protein). Improvements from baseline were explored with the paired t-test and the McNemar's test. Safety was evaluated by assessing the incidence of adverse events (AEs) and drug survival rates., Results: A total of 111 IFX-treated, 281 GLM-treated and 70 UST-treated patients were enrolled. Most baseline disease parameters remained similar over time in all three cohorts. UST-treated patients had lower mean baseline Disease Activity Score in 28 joints CRP, swollen joint based on 28 joints and higher PASI compared with patients treated with GLM. Treatment with IFX, GLM and UST was associated with significant improvements in all disease parameters over time (p<0.001) from baseline up to 84, 84 and 40 months, respectively.AEs were reported for 74.8%, 69.8% and 52.9% (138, 114 and 115 events/100 patient-years (PYs)) covering 325, 567 and 87 years of exposure for IFX-treated, GLM-treated and UST-treated patients, respectively. Severe AEs were reported in 19.8%, 8.5% and 5.7% (8.8, 7.2 and 8.0 events/100 PYs) in IFX-treated, GLM-treated and UST-treated patients, respectively. The proportion of patients who discontinued treatment were 63.1%, 50.9% and 50.0%, respectively., Conclusions: IFX, GLM and UST treatment significantly reduced disease activity and improved functionality in patients with PsA followed by routine clinical practice and had a safety profile similar to that previously reported in the literature., Trial Registration Number: NCT00741793., Competing Interests: Competing interests: PR has received consulting fees for Abbott, AbbVie, Amgen, BMS, Celgene, Janssen, Novartis, Pfizer and Roche; and received research grant from Janssen.

Nodular lichen myxoedematosus is a localised form of lichen myxoedematosus, a chronic idiopathic cutaneous mucinosis of known aetiology. Ustekinumab is a human interleukin-12/23 monoclonal antibody that could directly or indirectly increase mucin production. Herein, we report for the first time a case of nodular lichen myxoedematosus associated with ustekinumab., (© 2020 The Australasian College of Dermatologists.)

The reversible cerebral vasoconstriction syndrome (RCVS) is a common cause of thunderclap headache. Many trigger factors, such as the intake of vasoactive and less commonly immunosuppressive medication have previously been described. This article reports the first case of the occurrence of RCVS after the intake of ustekinumab in a female patient with a history of Crohn's disease.

A variety of interleukin-23 targeted drugs have been used to treat moderate to severe psoriasis, but it is not clear which is most effective. This network meta-analysis compared and summarized the short-term efficacy and safety of interleukin-23 (IL-23) targeted drugs in the treatment of moderate to severe psoriasis. PubMed, Embase, Web of Science, and Cochrane Library were used to search randomized controlled trials (RCTs) about the treatment of moderate to severe psoriasis with ustekinumab (Ust), guselkumab (Gus), tildrakizumab (Til), and risankizumab (Ris). Bayesian Network Meta-analysis (NMA) was used to calculate Psoriasis Area and Severity Index 75%, 90%; Physician Global Assessment score of 0 or 1 (PGA 0/1); Dermatology Life Quality Index of 0 or 1 (DLQI 0/1), and safety (adverse events [AEs]) effect estimates (odds ratio OR) and 95% confidence intervals. Direct, indirect, and network meta-analysis estimates were calculated using a random-effects model. The GRADE method was used to assess the quality of evidence for each pair-wise comparison. In addition, the surface under the cumulative ranking curve (SUCRA) analysis was used to rank the treatment level for each outcome indicator. This network meta-analysis included 14 RCTs with 8402 patients. The results indicate that the curative effect of the IL-23 targeted drugs is better than that of a placebo. Network meta-analysis showed that Ris90 mg and Ris180 mg were significantly more effective than Til (5, 25, 100, and 200 mg), Ust (45 mg, 90 mg, body weight-based administration), Gus 100 mg and Ris (75 and 150 mg). Regarding safety, there is no significant difference in the risk of adverse events between drugs targeting IL-23 and placebo. In addition, according to the ranking of SUCRA, Ris 90 mg has the best efficacy index for PASI 75 and PGA 0/1, with SUCRA values of 97.6% and 97.1%, respectively. Ris 180 mg ranked first in PASI 90 (91.1%), while Ris 75 mg performed best in DLQI 0/1 (73.7%). In this network meta-analysis, risankizumab showed the best curative effect in the short-term treatment of moderate to severe psoriasis, and the risk of adverse events was not significantly different from placebo. However, more research data are needed for further study in the field of cost to evaluate which drug strikes the most favorable balance among efficacy, safety, and cost of access., (© 2020 Wiley Periodicals LLC.)

A change of pricing policy in Spain have made both doses of ustekinumab (UST), 45 and 90 mg, recently available at the same price. Our primary objective was to evaluate effectiveness of UST 90 mg at 52 and 104 weeks in psoriasis patients in clinical practice; secondary objectives were to study the reasons for using this dose and to delineate its efficacy in patients previously treated with anti-IL17 drugs. 91.8% of the 141 patients treated with UST 90 started with 45 mg and later increased their dose. Clinicians changed dose due to weight over 100 kg in 20.6% of the cases and all the other dose changes were off-label to improve partial cutaneous or articular response or due to a previous failure of anti-IL17 therapy. After 12 months of UST 90 treatment, absolute PASI was lower than 3 in 87.5% of patients and lower than 1 in 72.2%. Efficacy data were even better for patients with body mass index (BMI) <25. UST 90 can be effective in patients with previous use of anti-IL17 drugs. It appears to be an alternative treatment option not only for high BMI patients, but also to increase the cutaneous or articular efficacy of the drug in patients with normal BMI., (© 2020 Wiley Periodicals LLC.)

Background: Both vedolizumab and ustekinumab can be considered for the treatment of Crohn's disease (CD) when anti-TNF treatment fails. However, head-to-head trials are currently not available or planned., Aim: To compare vedolizumab and ustekinumab in Crohn´s disease patients in a prospective registry specifically developed for comparative studies with correction for confounders., Methods: Crohn´s disease patients, who failed anti-TNF treatment and started vedolizumab or ustekinumab in standard care as second-line biological, were identified in the observational prospective Dutch Initiative on Crohn and Colitis Registry. Corticosteroid-free clinical remission (Harvey Bradshaw Index ≤4), biochemical remission (C-reactive protein ≤5 mg/L and fecal calprotectin ≤250 µg/g), combined corticosteroid-free clinical and biochemical remission, and safety outcomes were compared after 52 weeks of treatment. To adjust for confounding and selection bias, we used multiple logistic regression and propensity score matching., Results: In total, 128 vedolizumab- and 85 ustekinumab-treated patients fulfilled the inclusion criteria. After adjusting for confounders, ustekinumab-treated patients were more likely to achieve corticosteroid-free clinical remission (odds ratio [OR]: 2.58, 95% CI: 1.36-4.90, P = 0.004), biochemical remission (OR: 2.34, 95% CI: 1.10-4.96, P = 0.027), and combined corticosteroid-free clinical and biochemical remission (OR: 2.74, 95% CI: 1.23-6.09, P = 0.014), while safety outcomes (infections: OR: 1.26, 95% CI: 0.63-2.54, P = 0.517; adverse events: OR: 1.33, 95% CI: 0.62-2.81, P = 0.464; hospitalisations: OR: 0.67, 95% CI: 0.32-1.39, P = 0.282) were comparable between the two groups. The propensity score matched cohort with sensitivity analyses showed comparable results., Conclusions: Ustekinumab was associated with superior effectiveness outcomes when compared to vedolizumab, while safety outcomes were comparable after 52 weeks of treatment in CD patients who have failed anti-TNF treatment., (© 2020 The Authors.

Background: Brodalumab is a fully human anti-interleukin-17 receptor A monoclonal antibody efficacious for the treatment of adults with moderate-to-severe plaque psoriasis., Objective: This study summarizes malignancy rates in psoriasis clinical studies of brodalumab., Methods: Data were pooled from one phase II study and three large, multicenter, phase III randomized studies of brodalumab for the treatment of psoriasis, including two studies with randomization to brodalumab, ustekinumab, or placebo. Data from the 52-week (brodalumab and ustekinumab) and long-term (brodalumab) pools were summarized as exposure-adjusted or follow-up time-adjusted event rates per 100 patient-years (PY)., Results: Exposure-adjusted event rates per 100 PY at 52 weeks were lower with brodalumab (n = 4019; 3446 total PY of exposure) than with ustekinumab (n = 613; 495 total PY of exposure), including adjudicated malignancies (0.9 vs 2.6) and Surveillance, Epidemiology, and End Results (SEER)-adjudicated malignancies (0.3 vs 0.4). The exposure-adjusted event rate of adjudicated malignancies in the brodalumab group remained stable in the long-term analysis (0.9 [82 events])., Conclusions: Rates of malignancy among brodalumab-treated patients with psoriasis were generally low., Trial Registry: ClinicalTrials.gov identifier NCT00975637; NCT01101100; NCT01708590 (AMAGINE-1); NCT01708603 (AMAGINE-2); NCT01708629 (AMAGINE-3).

Background: Phase III trials have demonstrated the efficacy and safety of ustekinumab in moderate-to-severe ulcerative colitis (UC), but few real-world data are currently available., Aim: To assess short-term effectiveness and safety of ustekinumab in patients with UC., Methods: From January to September 2019, all patients with UC treated with ustekinumab in 20 French GETAID centres were retrospectively included. The primary outcome was steroid-free clinical remission (partial Mayo Clinic score ≤2) at weeks 12-16 without a rectal bleeding subscore >1., Results: Among the 103 patients included, 70% had been previously exposed to ≥2 anti-TNF agents and 85% to vedolizumab. At weeks 12-16, steroid-free clinical remission and clinical remission rates were 35.0% and 39.8% respectively; the absence of rectal bleeding with normal stool frequency was noted in 19.4% of patients. Two patients discontinued ustekinumab before the week 12-16 visit and underwent surgery. In multivariable analysis, a partial Mayo Clinic score >6 at inclusion (18.6% vs 46.7%, P = 0.003) and a history of both exposure to anti-TNF and vedolizumab therapies (27.3% vs 80.0%, P = 0.001) were negatively associated with steroid-free clinical remission at weeks 12-16. Adverse events occurred in 7.8% of patients and serious adverse events in 3.9% of patients., Conclusion: In a cohort of highly refractory patients with UC with multiple prior drug failures, ustekinumab provided steroid-free clinical remission in one-third of cases at weeks 12-16. Clinical severity and previous use of anti-TNF and vedolizumab therapies were associated with ustekinumab failure at weeks 12-16., (© 2020 John Wiley & Sons Ltd.)

Background: Biologic therapies in patients with Crohn's disease often yield low clinical and endoscopic remission rates. After multiple failed therapies, combining two biologic therapies is possibly the sole medical alternative to recurrent surgery. However, data on this approach are limited., Aims: To assess the efficacy and safety of concomitant use of two biologic therapies in the largest cohort to date of refractory Crohn's disease patients., Methods: Data were extracted from Crohn's disease patients started on dual biologic therapy at two referral centres. Biologics utilised include infliximab, adalimumab, vedolizumab, ustekinumab, certolizumab and golimumab. The primary outcome was endoscopic improvement (>50% reduction in Simplified Endoscopic Score-Crohn's disease [SES-CD] or explicitly stated). Endoscopic remission (SES-CD < 3 or stated), clinical response (Crohn's disease-patient-reported outcome-2 score [PRO2] reduced by 8), clinical remission (PRO2 < 8), and C-reactive protein (CRP) were also assessed., Results: A total of 22 patients with 24 therapeutic trials of dual biologic therapy were identified. The majority of patients had prior surgical resections (91%), stricturing (59%) or penetrating (36%) phenotype, and perianal fistulas (50%). Median number of prior failed biologics was 4. Endoscopic improvement occurred in 43% of trials and 26% achieved endoscopic remission. Fifty per cent had clinical response and 41% achieved clinical remission. There were significant post-treatment reductions in median SES-CD (14.0 [12.0-17.5] to 6.0 [2.5-8.0], P = 0.0005], PRO-2 (24.1 [20.3-27.0] to 13.4 [4.6-21.8], P = 0.002] and CRP (17.0 [11.0-24.0] to 9.0 [4.0-14.0], P = 0.02). Presence of perianal fistulas decreased from 50% to 33%. Adverse events occurred in 13% of trials., Conclusion: Dual biologic therapy was associated with clinical, biomarker and endoscopic improvements in selected patients with refractory Crohn's disease who failed multiple biologics. Further studies are needed to validate this approach., (© 2020 John Wiley & Sons Ltd.)

Rationale: Ustekinumab is a biological agent that inhibits interleukin 12 and 23 and has been approved for the treatment of moderate and severe plaque psoriasis. There have been case reports that raise concerns about its oncogenic potential. We are the first authors to report a case of Hodgkin lymphoma in a psoriatic patient receiving ustekinumab., Patient Concerns: A 22-year-old asymptomatic female patient presented to our department to investigate an enlarged cervical lymph node. Her past history was unremarkable, except for psoriasis since age 13. Two months before presentation the decision to administer Ustekinumab was taken and the patient had already received 3 doses., Diagnoses: During workup a Stage IV Hodgkin lymphoma was discovered., Interventions: Ustekinumab administration was discontinued. The patient received treatment with the ABVD regimen., Outcomes: The patient's disease was refractory to the above-mentioned treatment. Therefore, a more aggressive regimen (BEACOPP escalated) was administered., Lessons: Growing postmarketing surveillance data and case reports indicate that further research is warranted in order to elucidate a potential association between Ustekinumab and malignancy.

Alopecia areata (AA) is an autoimmune condition that affects up to 2% of the general population. Currently available treatment options for AA are of limited efficacy and can be associated with adverse effects. The advancement in understanding of the genetic and molecular mechanisms of AA has led to the development of novel treatment options, with the Janus kinase (JAK) inhibitor class of drugs at the forefront of ongoing clinical trials. Platelet-rich plasma, fecal transplants, and cytokine-targeted therapy with ustekinumab and dupilumab have also been shown to regrow hair in patients with AA in individual case reports or small studies. Several other novel therapies have preliminary data or are being tested in clinical trials.

Objective: To evaluate the efficacy and safety of ustekinumab through 1 year in a phase II trial in patients with systemic lupus erythematosus (SLE)., Methods: Eligible patients were diagnosed as having clinically active SLE (based on Systemic Lupus International Collaborating Clinics criteria), despite standard background therapy. Active disease was defined by an SLE Disease Activity Index 2000 (SLEDAI-2K) score of ≥6 as well as having ≥1 British Isles Lupus Assessment Group (BILAG) A organ domain score and/or ≥2 BILAG B organ domain scores present at screening. Patients (n = 102) were randomized (3:2) to receive either ustekinumab (~6 mg/kg of single intravenous infusion at week 0, then 90-mg subcutaneous injections every 8 weeks beginning at week 8) or a matching placebo added to standard therapy. At week 24, the placebo group crossed over to receive a subcutaneous 90-mg dose of ustekinumab every 8 weeks, and the original ustekinumab group continued to receive therapy through week 40. Maintenance of efficacy was assessed using the SLEDAI-2K, the SLE Responder Index 4 (SRI-4), physician global assessment, and mucocutaneous and joint disease measures in a modified intent-to-treat population., Results: SRI-4 response rates were significantly greater in the ustekinumab group (62%) versus the placebo group (33%) in the week 24 primary end point analysis (P = 0.006) and were maintained at week 48 (63.3%) in the ustekinumab group. In the ustekinumab group, response rates across other disease measures were also maintained through week 48. Among patients in the placebo group who crossed over to ustekinumab treatment (n = 33), increased response rates across efficacy measures were noted. Among all ustekinumab-treated patients, 81.7% had ≥1 adverse event (AE), and 15.1% had ≥1 serious AE through week 56. No deaths, malignancies, opportunistic infections, or tuberculosis cases were observed., Conclusion: Ustekinumab provided sustained clinical benefit in patients with SLE through 1 year, with a safety profile consistent with other indications., (© 2019, American College of Rheumatology.)

Introduction: Ustekinumab is an effective treatment of Crohn's disease (CD). Real-world data addressing the efficacy and safety of ustekinumab are scarce., Aim: Our aim was to assess the safety and efficacy of ustekinumab in a large national patient cohort., Methods: A prospective multicenter study, in which we followed patients with active CD treated with ustekinumab for 24 weeks. Induction dose was intravenous ranging from 260 to 520 mg, according to body weight, followed by 90 mg doses given subcutaneously every 8 weeks. Clinical response was defined as a reduction of at least 1 severity category, as defined by Harvey-Bradshaw index (HBI). Patients with HBI < 5 were considered to be in clinical remission. Patients who stopped needing steroids at week 24 were defined as being in steroid-free clinical remission., Results: A total of 106 CD patients from eight Israeli centers were included. All patients were previously exposed to at least one biological agent. Our cohort consisted of 65 (61.3%) females. Mean age was 41 ± 14 years with an average disease duration of 12.2 ± 8 years. A total of 96 (90.5%) patients continued treatment throughout week 24. Clinical response was observed in 52% of these patients with mean HBI reduction from 8.34 ± 3.8 to 6.8 ± 4.4 at week 24 ( p  = 0.001). Clinical remission was achieved in 33 patients (31.1%). Moreover, the number of patients requiring steroid treatment was reduced by 66% at week 24. Out of 106 patients, 11 patients (10.4%) discontinued treatment: 3 due to adverse events (2.8%), 7 due to a lack of response, and 1 who was lost to follow-up. Following 24 weeks of treatment, 15 patients reported minor adverse events., Conclusions: In a large real-world Israeli cohort of non-naïve-to-biological-treatment CD patients, ustekinumab was effective and safe in induction of clinical remission with a significant reduction in the number of patients requiring steroid treatment.

Background: The cardiovascular safety profile of biologic therapies used for psoriasis is unclear., Objectives: To compare the risk of major cardiovascular events (CVEs; acute coronary syndrome, unstable angina, myocardial infarction and stroke) in patients with chronic plaque psoriasis treated with adalimumab, etanercept or ustekinumab in a large prospective cohort., Methods: Prospective cohort study examining the comparative risk of major CVEs was conducted using the British Association of Dermatologists Biologics and Immunomodulators Register. The main analysis compared adults with chronic plaque psoriasis receiving ustekinumab with tumour necrosis-α inhibitors (TNFi: etanercept and adalimumab), whilst the secondary analyses compared ustekinumab, etanercept or methotrexate against adalimumab. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using overlap weights by propensity score to balance baseline covariates among comparison groups., Results: We included 5468 biologic-naïve patients subsequently exposed (951 ustekinumab; 1313 etanercept; and 3204 adalimumab) in the main analysis. The secondary analyses also included 2189 patients receiving methotrexate. The median (p25-p75) follow-up times for patients using ustekinumab, TNFi, adalimumab, etanercept and methotrexate were as follows: 2.01 (1.16-3.21), 1.93 (1.05-3.34), 1.94 (1.09-3.32), 1.92 (0.93-3.45) and 1.43 (0.84-2.53) years, respectively. Ustekinumab, TNFi, adalimumab, etanercept and methotrexate groups had 7, 29, 23, 6 and 9 patients experiencing major CVEs, respectively. No differences in the risk of major CVEs were observed between biologic therapies [adjusted HR for ustekinumab vs. TNFi: 0.96 (95% CI 0.41-2.22); ustekinumab vs. adalimumab: 0.81 (0.30-2.17); etanercept vs. adalimumab: 0.81 (0.28-2.30)] and methotrexate against adalimumab [1.05 (0.34-3.28)]., Conclusions: In this large prospective cohort study, we found no significant differences in the risk of major CVEs between three different biologic therapies and methotrexate. Additional studies, with longer term follow-up, are needed to investigate the potential effects of biologic therapies on incidence of major CVEs., (© 2019 The Authors.

Background: Obesity is associated with psoriasis and negatively affects response to therapy., Objectives: To evaluate the efficacy and safety of brodalumab in nonobese vs. obese patients with psoriasis., Methods: This is a post hoc analysis of the prospective, phase III, multicentre, randomized, placebo- and active-comparator-controlled AMAGINE-2 and AMAGINE-3 trials, in which patients were randomized to treatment with brodalumab 210 mg every 2 weeks, ustekinumab or placebo for a 12-week induction phase. At week 12, patients who received brodalumab 210 mg every 2 weeks continued brodalumab, those treated with ustekinumab continued ustekinumab, and those who received placebo switched to brodalumab 210 mg every 2 weeks. Patients were categorized by body mass index (BMI) category (< 30 or ≥ 30 kg m -2 ) and efficacy was evaluated using the physician-rated Psoriasis Area and Severity Index and static Physician's Global Assessment instruments., Results: In total, 281 of 687 patients (40·9%) were obese. Skin clearance was comparable across BMI subgroups in brodalumab-treated patients. Psoriasis Area and Severity Index 100% improvement rates in nonobese and obese patients at week 12 were 54·1% and 49·5%, respectively, and at week 52 they were 72·6% and 64·8%, respectively. Week 12 ustekinumab responses were lower than brodalumab responses and were 6-17% lower in obese than in nonobese patients. No appreciable differences in overall safety were observed between nonobese and obese patients., Conclusions: The efficacy and safety of brodalumab did not differ between patients with moderate-to-severe psoriasis who had a BMI < 30 kg m -2 or a BMI ≥ 30 kg m -2 ., (© 2019 British Association of Dermatologists.)

Introduction : Treatment of ulcerative colitis (UC) aims to control symptoms and to suppress intestinal inflammation. Despite considerable advances, a proportion of patients do not respond to currently available drugs. The interleukin (IL)-23 axis plays a significant role in the pathogenesis of UC and has thus become an important target for drug development. Areas covered : The review briefly summarizes the pathophysiology of the IL-12/23 axis and provides a synopsis of the available evidence for efficacy and safety of ustekinumab, mirikizumab (LY3074828), risankizumab (BI655066/ABBV066), brazikumab (MEDI2070; formerly AMG139) and guselkumab (CNTO1959) in UC. We also provide an overview of ongoing and anticipated trials in this field. Expert opinion : A Phase 2 trial with mirikizumab and a Phase 3 trial with ustekinumab have demonstrated the efficacy of anti-IL-23 agents in achieving clinical and endoscopic outcomes in UC with a favorable safety profile. Trials of other anti-IL-23 agents in UC are under way and designed to explore head-to-head efficacy with existing biologics, as well as the prospect of combination biological therapy. Apart from data on longer term efficacy and safety, future trials should also explore strategies to inform the positioning of IL-23 antagonists in therapeutic algorithms.

We report on a patient with severe psoriasis vulgaris who developed drug-induced interstitial lung disease (DILD) during treatment with ustekinumab. The diagnosis was based on coincidence with start of therapy, high-resolution computer tomography of the thorax and bronchoalveolar lavage. After discontinuation of the treatment with ustekinumab the clinical symptoms and the chest scan results improved. This case highlights a possible adverse event of ustekinumab.

Backgrounds and Aims: Fatigue is prevalent in patients with inflammatory bowel diseases [IBD]. Biologic therapy is effective in achieving symptomatic and endoscopic remission, but its impact on fatigue is less well established. Our aim is to define the longitudinal trajectory of fatigue over 1 year in patients initiating biologic therapy., Methods: This prospective cohort enrolled patients diagnosed with Crohn's disease [CD] or ulcerative colitis [UC] initiating biologic therapy with infliximab, adalimumab, ustekinumab, or vedolizumab. Fatigue was quantified using the seven-point fatigue question in the Short Inflammatory Bowel Disease Questionnaire [SIBDQ]. A score of ≤4 for this question was used to define fatigue. Multivariable regression models adjusting for relevant confounders examined the independent association between attaining clinical remission and resolution of fatigue., Results: Our study included 326 patients [206 CD, 120 UC] initiating biologic therapy [144 anti-tumour necrosis factor, 129 vedolizumab, 63 ustekinumab]. A total of 61% of the included patients reported significant fatigue at baseline. This was associated with female gender, depressive symptoms, active disease, and disturbed sleep [p < 0.001]. Among the 198 patients who were fatigued at therapy initiation, 86 [70%], 55 [63%], and 44 [61%] remained fatigued at Week 14, 30, and 54, respectively. At each of these time points, achieving clinical remission was associated with lower likelihood of persistent fatigue. However, despite achieving remission, 35%, 30%, and 28% of patients experienced persistent fatigue at Week 14, 30, and 54, respectively., Conclusions: Fatigue is common in IBD. Though biologic therapy improves fatigue parallel symptomatic improvement, a significant proportion continue to experience persistent fatigue up to 1 year., (Copyright © 2019 European Crohn’s and Colitis Organisation (ECCO).

Introduction: Ustekinumab, a monoclonal antibody that blocks interleukins 12/23, has proven in clinical trials its efficacy in inducing and maintaining clinical remission of Crohn's disease (CD). Its effectiveness and safety in actual clinical practice is less known and may differ from trials., Objective: To evaluate its effectiveness and safety in clinical practice (intravenous induction pattern essentially), such as induction and over the long term, in patients with CD refractory to biological treatment., Material and Methods: Multicentre retrospective analysis (6 hospitals in Aragón), which includes all patients (N=69) with CD undergoing treatment with ustekinumab (either with intravenous or subcutaneous induction), who had at least 16 weeks of follow-up. The clinical response or remission has been evaluated at weeks 16, 24, 32 and 48 using the Harvey-Bradshaw index., Results: A total of 69 patients have been included, mean age 42 years, 54% men. A percentage of 89.86 (95% CI [0.805, 0.949]) of the patients presented clinical improvement at week 16 (15.95% remission, 73.92% response). In the subsequent follow-up, this response has been maintained. Age (OR 0.95, P=.028) and smoking habits (OR 0.19, P=.027) have been identified by an ordinal regression model as predictors of poor treatment response while the need for biological change due to adverse effect (OR 96, P=.00017) and due to loss of secondary response (OR 7.07, P=.034) have been predictors of good response. No serious adverse effects have been reported that forced them to stop taking ustekinumab., Conclusion: Ustekinumab is effective and safe in real clinical practice to achieve induction and maintenance of the response in patients with refractory CD. Tobacco and age have been shown to be predictors of poor response, while the indication for adverse effect to previous biological and for loss of secondary response has been shown to be predictors of good response., (Copyright © 2019 Elsevier España, S.L.U.

Leukocytoclastic vasculitis is a single-organ, skin-isolated small vessel vasculitis. It can be a side effect of many common drugs, including biological agents. Unlike with other drugs, leukocytoclastic vasculitis induced by biological agents may have a prolonged latency period. We report the first case of ustekinumab-induced leukocytoclastic vasculitis in a patient with inflammatory bowel disease., (Copyright © 2019 European Crohn’s and Colitis Organisation (ECCO).

Background: Antidrug antibodies (ADAs) may change pharmacokinetic or pharmacodynamic profiles of biologic therapies, potentially decreasing efficacy., Objective: To evaluate the potential effects of brodalumab immunogenicity on safety, efficacy, and retreatment., Methods: Data from 1 phase 2 and 3 phase 3 studies of brodalumab in psoriasis were analyzed., Results: Overall, 2.7% of patients had positive test results for binding ADAs after receiving brodalumab; ADAs were transient in 1.4% of patients, and there were no neutralizing ADAs. Among ADA-positive patients, 60.0% (3/5) achieved a static physician's global assessment score of 0 or 1 at week 12 in the group receiving the brodalumab 210 mg every 2 weeks, compared with 79.1% (1131/1429) of ADA-negative patients. All patients (100%) who experienced return of disease and were retreated with brodalumab 210 mg every 2 weeks (none were ADA positive) achieved at least a 75% improvement in Psoriasis Area And Severity Index, ≥90% of whom regained response by week 8 of retreatment. Hypersensitivity reactions were less frequent with brodalumab than with placebo. Injection site reactions occurred in 1.8% of patients treated with brodalumab versus 2% of patients treated with ustekinumab., Limitations: Retreatment could be assessed in only 1 phase 3 brodalumab study., Conclusion: Brodalumab compares favorably with other biologics in terms of immunogenicity and high rates of efficacy recapture upon retreatment., (Copyright © 2019 American Academy of Dermatology, Inc.

Background: Randomized controlled trials have shown the efficacy and safety of brodalumab in patients with moderate to severe plaque psoriasis., Objective: To evaluate the efficacy and safety of brodalumab through 120 weeks of treatment in the AMAGINE-2 trial., Methods: Patients received ustekinumab through week 52 followed by brodalumab 210 mg every 2 weeks, continuous brodalumab 210 mg every 2 weeks, or any dose of brodalumab. Efficacy data were reported through 120 weeks by using observed data, last observation carried forward, and nonresponder imputation analyses., Results: Of patients who received brodalumab 210 mg every 2 weeks, 84.4%, 75.6%, and 61.1% achieved 75%, 90%, and 100% improvement from baseline in Psoriasis Area and Severity Index at 120 weeks (observed data analysis), respectively. Patients who received brodalumab 210 mg every 2 weeks after receiving ustekinumab through 52 weeks achieved a similar skin clearance response as patients who received continuous brodalumab 210 mg every 2 weeks. Safety through 120 weeks was comparable to that of the blinded study periods., Limitations: A large number of discontinuations toward the end of the study (31% in the final 6 months) were due to early termination and led to differences between observed data and nonresponder imputation results., Conclusions: Brodalumab is well tolerated and showed robust efficacy for more than 2 years., (Copyright © 2019 American Academy of Dermatology, Inc.

Background: Recently, ustekinumab a monoclonal antibody targeting interleukin-12 and -23 and successfully used in Crohn's disease also has been shown to be effective in induction and maintaining remission in patients with moderate to severe ulcerative colitis in a large phase 3 trial. However, no observational data on the use of ustekinumab in ulcerative colitis in daily clinical practice is available., Aim: The purpose of this study was to assess the clinical outcomes achieved with ustekinumab as rescue treatment in therapy-refractory or -intolerant ulcerative colitis in a real-life setting., Methods: A retrospective data analysis was performed in 19 ulcerative colitis patients who were intolerant or refractory to all of the following drugs: steroids, purine-analogues, tumour necrosis factor antibodies and vedolizumab. To all patients ustekinumab was provided as a rescue treatment (intravenous induction with 6 mg/kg, followed by week subcutaneous injection once every eight weeks of 90 mg). The primary outcome was achievement of clinical remission at one year, defined as score of ≤ 3 points in the Lichtiger score (colitis activity index). Patients were evaluated regularly and a colonoscopy was performed before the start and at the end of the observation. Ethical approval was provided by Ethikkommission Ärztekammer Hamburg (PV 5539)., Results: In five patients, therapy was stopped due to refractory disease or side effects. In all remaining 14 patients the median colitis activity index dropped from 8.5 points (range 1-12) at start to 2.0 points at one year (range 0-5.5) and Mayo endoscopy scores fell from a median of two points (range 1-3, mean of 2.3) at start to a median of one point (range 1-3, mean of 1.4) at one year. Including the five drop-outs, clinical remission was achieved in 53% of the 19 patients at one year., Conclusions: In accordance with the UNIFI (A Study to Evaluate the Safety and Efficacy of Ustekinumab Induction and Maintenance Therapy in Participants With Moderately to Severely Active Ulcerative Colitis) trial our real-life data support ustekinumab as an effective and safe treatment option in therapy refractory moderate to severe ulcerative colitis with a history of biological therapies.

Introduction : Psoriatic arthritis (PsA) is characterized by chronic inflammation mediated by pro-inflammatory cytokines, with clinical features resulting from dysfunctional integrated signaling pathways affecting different constituents of the immune system. Increased understanding of the processes responsible for enthesitis, synovial inflammation, joint erosion, and new bone formation during PsA has led to development of biologic therapies targeting these cytokines. There is an increased risk of opportunistic infections in patients with PsA, and this risk is increased further with targeted biologic therapy. Areas covered : This paper reviews the role of the interleukin (IL)-12, IL-23 and IL-17 axis in the pathogenesis of PsA. The data suggest that ustekinumab is associated with a low risk of infections in patients with PsA, including tuberculosis or hepatitis reactivation. No live vaccines can be safely administered; ustekinumab is contraindicated/cannot be given with live vaccines. However, long-term treatment with ustekinumab does not impair the immune response to these vaccines when administered after an appropriate interval. Expert opinion : Ustekinumab is associated with a low risk of serious and opportunistic infections. More research is needed to confirm these findings specifically in patients with PsA, and comparative studies are needed to investigate the relative risk of infection with different biologics.

Background: Patients recruited in randomized controlled trials (RCTs) for biologic therapies in psoriasis are not fully representative of the real-world psoriasis population., Objectives: Firstly, to investigate whether patient characteristics are associated with being included in a psoriasis RCT. Secondly, to estimate the differences in the incidence of severe adverse events (SAEs) and the response rate between RCT and real-world populations of patients on biologic therapies for psoriasis using a standardization method., Methods: Data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) were appended to individual participant-level data from two RCTs assessing ustekinumab in patients with psoriasis. Baseline variables were assessed for association of being in an RCT using a multivariable logistic regression model. Propensity score weights were derived to reweigh the registry population so that variables had the distribution of the trial population. We measured the C-statistic of the model with trial status as the dependent variable, and the risk differences in the incidence rate of SAEs in the first year and Psoriasis Area and Severity Index (PASI) after 6 months in the BADBIR cohort before and after weighting., Results: In total 6790 registry and 2021 RCT participants were included. The multivariable logistic regression model had a C-statistic of 0.82 [95% confidence interval (CI) 0.81-0.83]. The risk differences for the incidence rate of SAEs and the proportion of patients with PASI < 1.5 were 9.27 (95% CI -3.91-22.5) per 1000 person-years and 0.95 (95% CI -1.98-4.15), respectively., Conclusions: Our results suggest that RCTs of biologic therapies in patients with psoriasis are not fully representative of the real-world population, but this lack of external validity does not account for the efficacy-effectiveness gap. What's already known about this topic? Patients with psoriasis who would not be eligible for randomized controlled trials (RCTs) investigating biologic therapies have a greater risk of serious adverse events and lower treatment effectiveness than patients who would have been eligible. What does this study add? Baseline patient characteristics were shown to be predictive of whether a patient would have been eligible for enrolment in an RCT for psoriasis biologic therapy. We did not find any efficacy-effectiveness gap between the sample representative of the real-world population of patients with psoriasis and the sample representative of the RCT population. Factors outside of baseline patient characteristics, such as observer effect and higher adherence in RCTs, may be more influential in any efficacy-effectiveness gap between trial and real-world populations of patients with psoriasis., (© 2019 The Authors.

Background: The evidence regarding the association of preoperative biologic exposure and postoperative outcomes remains controversial for both antitumor necrosis factor agents and vedolizumab and largely unknown for ustekinumab., Objective: The purpose of this study was to determine differences in the rates of 30-day postoperative overall infectious complications and intra-abdominal septic complications among the 3 classes of biologic therapies as compared with no biologic therapy., Design: This was a retrospective review., Settings: The study was conducted at an IBD referral center., Patients: Adult patients with Crohn's disease who received an antitumor necrosis factor, vedolizumab, ustekinumab, or no biologic therapy within 12 weeks of a major abdominal operation between May 20, 2014, and December 31, 2017, were included., Main Outcomes Measures: Thirty-day overall postoperative infectious complications and intra-abdominal septic complications were measured., Results: A total of 712 patients with Crohn's disease were included; 272 patients were exposed to an antitumor necrosis factor agents, 127 to vedolizumab, 38 to ustekinumab, and 275 to no biologic therapy within the 12 weeks before an abdominal operation. Patients exposed to a biologic were more likely to be taking a concurrent immunomodulator, but there was no difference in concurrent corticosteroid usage. The particular class of biologic was not independently associated with total overall infectious complications. Vedolizumab was associated with an increased rate of intra-abdominal sepsis on univariate analysis but not on multivariable analysis. Combination immunosuppression was associated with both an increased rate of overall postoperative infectious complications and intra-abdominal sepsis., Limitations: The study was limited by its retrospective design and single-center data., Conclusions: The overall rate of total infectious complications or intra-abdominal septic complications was not increased based on preoperative exposure to a particular class of biologic. Rates increased with combination immunosuppression of biologic therapy with corticosteroids and previous abdominal resection. See Video Abstract at http://links.lww.com/DCR/B24. BIOLÓGICOS Y COMPLICACIONES POSTOPERATORIAS DE 30 DÍAS DESPUÉS DE LAS OPERACIONES ABDOMINALES PARA LA ENFERMEDAD DE CROHN: ¿EXISTEN DIFERENCIAS EN LOS PERFILES DE SEGURIDAD?:: La evidencia sobre la asociación de la exposición biológica preoperatoria y los resultados postoperatorios sigue siendo controvertida controversial tanto para los agentes del factor de necrosis tumoral (anti-TNF) como para el vedolizumab, y en gran parte desconocida para el ustekinumab.Determinar las diferencias en las tasas de complicaciones infecciosas generales postoperatorias de 30 días y complicaciones sépticas intraabdominales entre las tres clases de terapias biológicas en comparación con ninguna terapia biológica.Revisión retrospectiva.centro de referencia de la enfermedad inflamatoria intestinal.Pacientes adultos con enfermedad de Crohn que recibieron un factor de necrosis antitumoral, vedolizumab, ustekinumab o ningún tratamiento biológico dentro de las 12 semanas de una operación abdominal mayor entre el 5/20/2014 y el 12/31/2017.Complicaciones infecciosas postoperatorias generales de 30 días, complicaciones sépticas intraabdominales.Se incluyeron setecientos doce pacientes con enfermedad de Crohn; 272 pacientes fueron expuestos a un anti-TNF, 127 a vedolizumab, 38 a ustekinumab y 275 a ninguna terapia biológica dentro de las 12 semanas previas a una operación abdominal. Los pacientes expuestos a un producto biológico tenían más probabilidades de tomar un inmunomodulador concurrente, pero no hubo diferencias en el uso simultáneo de corticosteroides.

Background: Three biotherapies - etanercept, adalimumab and ustekinumab - are licensed in childhood psoriasis. The few data available on their efficacy and tolerance are mainly derived from industry trials. However, biological drug survival impacts long-term performance in real-life settings., Objective: The objective of this study was to evaluate the survival rates of biological therapies in children with psoriasis in real-life conditions. Secondary objectives were to evaluate the factors associated with the choice of the biological therapy and to report severe adverse events., Materials and Methods: This study was an observational retrospective study. Data were extracted from the clinical records of 134 children. Kaplan-Meier estimates were used to analyse drug survival overall and in subgroups of plaque psoriasis, bio-naïve and non-naïve patients., Results: We analysed 184 treatment courses: 70 with etanercept, 68 with adalimumab and 46 with ustekinumab. Factors associated with the choice of first-line biological agent were age at initiation (younger for adalimumab, P < 0.0001), age at onset of psoriasis (younger for adalimumab and etanercept, P = 0.03) and baseline Psoriasis Assessment Severity Index and Physician global assessment (both higher for adalimumab, P < 0.001). Drug survival rates were higher for ustekinumab than for adalimumab and etanercept (P < 0.0001) for all treatment and all psoriasis types, plaque-type psoriasis (P = 0.0003), patients naïve for biological agents (P = 0.0007) and non-naïve patients (P = 0.007). We reported eight serious adverse events (SAEs): severe infections (n = 3), significant weight gain (n = 2), psoriasis flare (n = 1) and malaise (n = 1). Biological therapy was discontinued in three children (one with psoriasis flare and two with weight gain). Only the two cases of weight gain resulted in an unfavourable outcome., Conclusions: Our real-life comparative study found that ustekinumab had the best drug survival outcome. The profile of SAEs in children was comparable to that in adults. These results will assist dermatologists in the decision-making process when choosing treatment options for children with psoriasis in daily practice., (© 2019 European Academy of Dermatology and Venereology.)

Background & Aims: Although ustekinumab is an effective therapy for moderate to severe Crohn's disease (CD), its effects on the microscopic manifestations of CD are unknown., Methods: We evaluated the effects of ustekinumab on histologic CD activity in an analysis of data from 251 participants in phase 3 induction and maintenance studies. Two endoscopic biopsy samples were collected at weeks 0, 8, and 44 from the ileum, splenic flexure, and rectum (18 biopsy samples from each patient). Histologic activity was assessed based on global histology activity scores (GHASs)., Results: At week 8, the mean GHAS was significantly reduced after ustekinumab induction treatment (from 10.4 ± 7.0 to 7.1 ± 5.9; P < .001) but not in patients who received placebo (from 9.2 ± 6.4 to 7.8 ± 6.2). At week 44 in the randomized maintenance therapy population, the mean GHAS remained reduced from week 8 in patients who received subcutaneous ustekinumab (90 mg every 8 weeks; from 7.4 ± 7.7 to 6.1 ± 4.7) but not every 12 weeks (from 5.3 ± 3.9 to 8.7 ± 4.1) or placebo (from 9.2 ± 3.8 to 10.9 ± 7.1). In the pooled (randomized and nonrandomized) maintenance therapy population, histologic improvement continued in patients given ustekinumab every 8 weeks (from 7.1 ± 6.2 to 5.2 ± 4.2; P < .0001) but not in those given ustekinumab every 12 weeks (from 6.1 ± 5.7 to 7.2 ± 5.1) or placebo (from 8.2 ± 4.2 to 8.9 ± 6.8). A significantly greater proportion of patients achieved histologic response (≥50% decrease in GHAS from baseline) at week 44 if they received ustekinumab every 8 weeks (50% in the randomized maintenance population and 54% in the pooled maintenance population) compared with every 12 weeks (17% and 39% in the randomized and pooled populations, respectively) or placebo (0% and 22% in the randomized and pooled populations, respectively) (P = .0137 for every 8 weeks vs placebo and P = .3529 for every 12 weeks vs placebo in the randomized population; P = .0168 for every 8 weeks vs placebo and P = .3069 for every 12 weeks vs placebo in the pooled population). Regional and overall mean GHASs correlated with the simple endoscopic score for CD (r = .6255, P < .0001). Multivariate analysis found an association between histologic improvement and endoscopic or histologic burden at baseline., Conclusions: In an analysis of data from participants in phase 3 induction and maintenance trials, we found histologic improvement in a greater proportion of patients given ustekinumab vs placebo. The largest improvements occurred in patients who received ustekinumab maintenance therapy every 8 weeks. ClinicalTrials.gov nos.

Background: The efficacy of ustekinumab, an antagonist of the p40 subunit of interleukin-12 and interleukin-23, as induction and maintenance therapy in patients with ulcerative colitis is unknown., Methods: We evaluated ustekinumab as 8-week induction therapy and 44-week maintenance therapy in patients with moderate-to-severe ulcerative colitis. A total of 961 patients were randomly assigned to receive an intravenous induction dose of ustekinumab (either 130 mg [320 patients] or a weight-range-based dose that approximated 6 mg per kilogram of body weight [322]) or placebo (319). Patients who had a response to induction therapy 8 weeks after administration of intravenous ustekinumab were randomly assigned again to receive subcutaneous maintenance injections of 90 mg of ustekinumab (either every 12 weeks [172 patients] or every 8 weeks [176]) or placebo (175). The primary end point in the induction trial (week 8) and the maintenance trial (week 44) was clinical remission (defined as a total score of ≤2 on the Mayo scale [range, 0 to 12, with higher scores indicating more severe disease] and no subscore >1 [range, 0 to 3] on any of the four Mayo scale components)., Results: The percentage of patients who had clinical remission at week 8 among patients who received intravenous ustekinumab at a dose of 130 mg (15.6%) or 6 mg per kilogram (15.5%) was significantly higher than that among patients who received placebo (5.3%) (P<0.001 for both comparisons). Among patients who had a response to induction therapy with ustekinumab and underwent a second randomization, the percentage of patients who had clinical remission at week 44 was significantly higher among patients assigned to 90 mg of subcutaneous ustekinumab every 12 weeks (38.4%) or every 8 weeks (43.8%) than among those assigned to placebo (24.0%) (P = 0.002 and P<0.001, respectively). The incidence of serious adverse events with ustekinumab was similar to that with placebo. Through 52 weeks of exposure, there were two deaths (one each from acute respiratory distress syndrome and hemorrhage from esophageal varices) and seven cases of cancer (one each of prostate, colon, renal papillary, and rectal cancer and three nonmelanoma skin cancers) among 825 patients who received ustekinumab and no deaths and one case of cancer (testicular cancer) among 319 patients who received placebo., Conclusions: Ustekinumab was more effective than placebo for inducing and maintaining remission in patients with moderate-to-severe ulcerative colitis.

The 52-week results from the CLEAR (NCT02074982) study showed high and superior efficacy of secukinumab versus ustekinumab in clearing skin and improving patient-reported outcomes, with comparable safety profile in subjects with moderate to severe psoriasis. Here, we analyzed the efficacy and safety of secukinumab in Asian subjects from the CLEAR study. In this double-blind, phase IIIb study, eligible subjects with moderate to severe plaque psoriasis were randomized (1:1) to receive s.c. injection of secukinumab 300 mg or ustekinumab as per label. Of 62 subjects included in Asian subanalyses, 23 were randomized to secukinumab and 39 to ustekinumab. A significantly higher proportion of subjects achieved 90% or more improvement in Psoriasis Area and Severity Index (PASI 90) with secukinumab versus ustekinumab at week 16 (78.3% vs 35.9%, P = 0.0010) and at week 52 (60.9% vs 33.3%, P = 0.0196). Similarly, a higher proportion of subjects achieved PASI 100 with secukinumab versus ustekinumab at week 16 (43.5% vs 10.3%, P = 0.0029) and at week 52 (30.4% vs 12.8%, P = 0.0704). The median time to achieve 50% improvement in baseline PASI was 2.8 weeks in the secukinumab group versus 6.3 weeks in the ustekinumab group. The safety profile of secukinumab was in line with the known profile and no deaths occurred. Overall, 95.7% and 84.6% of subjects remained on secukinumab and ustekinumab, respectively. Similar to the core study, secukinumab showed sustained and superior efficacy with faster response versus ustekinumab, and no new or unexpected safety concerns were identified, in Asian subjects with moderate to severe plaque psoriasis., (© 2019 Japanese Dermatological Association.)

Background: Ustekinumab [UST] is effective in Crohn's disease (CD) in the UNITI studies. Several real-world experience (RWE) studies with UST have been published to date. Our aim was to summarize the available RWE data for UST effectiveness and safety., Methods: A systematic review of the available RWE studies of UST for CD and pooled analysis of the available effectiveness and safety data was performed., Results: Eight relevant studies of 6 RWE were included for analysis. Data from 578 patients were pooled for analysis. Most patients (97.7%) were anti-TNF experienced. Pooled clinical response rate was 60%, 62%, 49% at 12, 24 and 52 weeks respectively (95% CI (0.42-0.77), (0.48-0.75), (0.37-0.62)). Pooled remission rate was 39% (95% CI (0.18-0.65)) at 24 weeks and pooled endoscopic response rate was 63% (95% CI (0.53-0.72)) after approximately one year of UST; 134 adverse events (AE) were reported in total, pooled proportion 21% (95% CI (0.12-0.35)). Serious AE were reported in 19 patients, pooled proportion 5% (95% CI (0.03-0.08)). Infections were reported in 38, pooled proportion 6% (95% CI (0.04-0.11))., Conclusion: Pooled analysis of the RWE data suggests that the real-world effectiveness and safety are comparable to that reported in the randomized control trials., (Copyright © 2019 Editrice Gastroenterologica Italiana S.r.l.
