Ustekinumab in psoriatic arthritis and related phenotypes.

ABSTRACT: Psoriatic arthritis (PsA) is an inflammatory arthritis that commonly occurs with psoriasis and is attributed to genetic, immunologic and environmental factors. The T-helper (Th)-17 pathway and the interleukin (IL)-23/IL-17 axis have become prominent players in PsA and considerably increased our understanding of disease pathogenesis. In this review article, we will focus on the emerging role of IL-12/23 and its blockade, in the pathogenesis and management of PsA as well as of psoriasis and inflammatory bowel disease. Ustekinumab, is a fully human monoclonal immunoglobulin (Ig)G1 antibody that binds specifically to the p40 subunit of IL-12 and IL-23, primarily inhibiting downstream Th-17 signalling pathways. Ustekinumab produced consistent and sustained clinical efficacy in two phase III clinical trials in PsA, PSUMMIT-1 and PSUMMIT-2, with data out to 52 weeks, and no new safety signals. PSUMMIT-1 included patients with active PsA despite conventional therapy who were all naïve to anti-tumour necrosis factor (TNF) agents, whereas PSUMMIT-2 also included anti-TNF experienced patients. Similarly, ustekinumab produced consistent clinical efficacy in two phase III clinical trials in psoriasis, PHOENIX-1 and PHOENIX-2, and in both induction and maintenance of moderate-to-severe Crohn's disease, UNITI-1, UNITI-2 and IM-UNITI, without an increased safety signal. Currently, ustekinumab is used in the treatment of PsA following the failure of nonsteroidal anti-inflammatory drugs (NSAIDs) and conventional disease-modifying antirheumatic drugs (DMARDs), and as an alternative to, or after failure of an anti-TNF agent.

Project description:To assess the comparative effectiveness and safety of novel biologic therapies in psoriatic arthritis (PsA) and to establish the position of the non-anti-tumor necrosis factor ? (TNF-?) biologic drugs in the treatment regimen of the disease. A systematic review and network meta-analysis (NMA) was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) requirements. Two investigators identified the studies, abstracted data, and assessed the risk of bias independently. The NMA was conducted for efficacy [American College of Rheumatology (ACR) criteria, ACR20 and ACR50; psoriasis area and severity index (PASI), PASI75] and safety outcomes [any adverse events (AEs) and serious adverse events (SAEs)]; treatments were ranked using the P score for each outcome. The PROSPERO registration number was 42017072200. MEDLINE/PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched from the inception of each database to July 10, 2017. Randomized controlled trials (RCTs) for abatacept, apremilast, secukinumab or ustekinumab in adults with moderate and severe PsA were included. The overall PsA population and anti-TNF-?-naive, anti-TNF-?-failure, or anti-TNF-?-experienced subpopulations were considered. We identified eight eligible RCTs and included them in the systematic review and NMA. Significant differences in ACR20 response rate were revealed between secukinumab 150 mg and apremilast 20 mg [relative risk; RR?=?2.55 (CI-confidence interval; 1.24, 5.23)] and between secukinumab 300 mg and apremilast 20 or 30 mg [RR?=?3.57 CI (1.48, 8.64) and RR?=?2.84 CI (1.18, 6.86), respectively]. Any AEs occurred more often in apremilast 20 and 30 mg compared with placebo [RR?=?0.58 CI (0.45, 0.74) and RR?=?0.58 CI (0.45, 0.75), respectively] but also compared with secukinumab 150 mg [RR?=?0.54 CI (0.35, 0.81) and RR?=?0.45 CI (0.35, 0.82), respectively]. No significant differences were revealed for SAEs among biologics and between biologics and placebo. In the overall population, as well as in the anti-TNF-?-naive subpopulation, secukinumab at a dose of 300 and 150 mg was ranked the highest for the ACR20 endpoint, while in the anti-TNF-?-experienced subpopulation, secukinumab 300 mg and apremilast 30 mg revealed the highest rank. Secukinumab 75 mg was the safest drug in terms of any AEs, but for SEAs the safest was ustekinumab 90 mg. Our study revealed no significant differences among non-anti-TNF-? biologics in the treatment of PsA in the comparisons performed with regards to the highest efficacy and safety. Both in the overall population and in the analyzed subpopulations, secukinumab 300 mg was ranked the highest for the ACR20 response rate. Secukinumab 300 mg was the safest drug in terms of any AEs, and ustekinumab 90 mg presented the lowest overall risk of SAEs. Head-to-head trials and evaluation of comparative efficacy and safety between non-TNF-? biologics are warranted to inform clinical decision making with a relevant treatment paradigm.

Project description:IntroductionTheoretical risks of biologic agents remain under study.ObjectiveThe aim of this study was to integrate 1-year safety data from 12 ustekinumab registrational trials.MethodsPatients had moderate-to-severe plaque psoriasis, active psoriatic arthritis (PsA) (± methotrexate), or moderate-to-severe Crohn's disease (CD; failed/intolerant of immunomodulators/corticosteroids). Psoriatic patients received subcutaneous ustekinumab 45/90 mg or placebo, generally at week 0, week 4, then every 12 weeks thereafter, while those with CD received a single intravenous ustekinumab dose (130 mg or weight range-based dosing of approximately 6 mg/kg) or placebo induction dose at week 0, followed by subcutaneous ustekinumab 90 mg at week 8 and every 8/12 weeks thereafter. The incidence rates of a priori-defined safety events were integrated post hoc (adjusted for duration of follow-up, reported per 100 patient-years [PYs]).ResultsAmong 6280 enrolled patients, 5884 ustekinumab-treated patients (psoriasis: 3117; PsA: 1018; CD: 1749) contributed 4521 PYs versus 674 PYs in placebo-treated patients through year 1 (829 PYs and 385 PYs during 8- to 16-week controlled periods). Combined across diseases among ustekinumab- versus placebo-treated patients, respective incidences/100 PYs (95% confidence intervals) of infections were 125.4 (122.2-128.7) versus 129.4 (120.9-138.3) through year 1, and not meaningfully increased in patients who did versus those who did not receive methotrexate (92.5 [84.2-101.5] vs. 115.3 [109.9-121.0]), or significantly increased in patients who did versus those who did not receive corticosteroids (116.3 [107.3-125.9] vs. 107.3 [102.0-112.8]) at baseline. Major adverse cardiovascular events (0.5 [0.3-0.7] vs. 0.3 [0.0-1.1]), malignancies (0.4 [0.2-0.6] vs. 0.2 [0.0-0.8]), and deaths (0.1 [0.0-0.3] vs. 0.0 [0.0-0.4]) were rare across indications.ConclusionsUstekinumab demonstrated a favorable and consistent safety profile across registrational trials in approved indications.Trial registrationsClinicalTrials.gov identifier: NCT00320216, NCT00267969, NCT00307437, NCT00454584, NCT00267956, NCT01009086, NCT01077362, NCT00265122, NCT00771667, NCT01369329, NCT01369342, and NCT01369355.

Project description: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.

Project description:Importance:Accumulating evidence indicates that there is an increased risk of cardiovascular disease among patients with psoriatic disease. Although an emerging concern that the risk of atrial fibrillation (AF) may also be higher in this patient population adds to the growing support of initiating early interventions to control systemic inflammation, evidence on the comparative cardiovascular safety of current biologic treatments remains limited. Objective:To evaluate the risk of AF and major adverse cardiovascular events (MACE) associated with use of ustekinumab vs tumor necrosis factor inhibitors (TNFi) in patients with psoriasis or psoriatic arthritis. Design, Setting, and Participants:This cohort study included data from a nationwide sample of 78 162 commercially insured patients in 2 US commercial insurance databases (Optum and MarketScan) from September 25, 2009, through September 30, 2015. Patients were included if they were 18 years or older, had psoriasis or psoriatic arthritis, and initiated ustekinumab or a TNFi therapy. Exclusion criteria included history of AF or receipt of antiarrhythmic or anticoagulant therapy during the baseline period. Exposures:Initiation of ustekinumab vs TNFi therapy. Main Outcomes and Measures:Incident AF and MACE, including myocardial infarction, stroke, or coronary revascularization. Results:A total of 60 028 patients with psoriasis or psoriatic arthritis (9071 ustekinumab initiators and 50 957 TNFi initiators) were included in the analyses. The mean (SD) age was 46 (13) years in Optum and 47 (13) in MarketScan, and 29 495 (49.1%) were male. Overall crude incidence rates (reported per 1000 person-years) for AF were 5.0 (95% CI, 3.8-6.5) for ustekinumab initiators and 4.7 (95% CI, 4.2-5.2) for TNFi initiators, and for MACE were 6.2 (95% CI, 4.9-7.8) for ustekinumab initiators and 6.1 (95% CI, 5.5-6.7) for TNFi initiators. The combined adjusted hazard ratio for incident AF among ustekinumab initiators was 1.08 (95% CI, 0.76-1.54) and for MACE among ustekinumab initiators was 1.10 (95% CI, 0.80-1.52) compared with TNFi initiators. Conclusions and Relevance:No substantially different risk of incident AF or MACE after initiation of ustekinumab vs TNFi was observed in this study. This information may be helpful when weighing the risks and benefits of various systemic treatment strategies for psoriatic disease.
