427 Long-term 4-year safety of upadacitinib in moderate-to-severe atopic dermatitis: results of an integrated analysis of phase 3 studies

Abstract Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by intense itch and eczematous skin lesions that can impact individuals at any age across any area of the body. There is a need for safe treatments for AD that provide rapid itch relief and skin clearance and that are suitable for long-term use. Upadacitinib is a selective, reversible oral Janus kinase 1 (JAK1) inhibitor, which is approved in multiple countries for the treatment of adolescents and adults with moderate-to-severe AD. The current analysis assessed the long-term safety for up to 4 years of upadacitinib 15 and 30 mg in adolescents and adults with moderate-to-severe AD, using integrated data from three ongoing global pivotal phase 3 studies. The Measure Up 1, Measure Up 2, and AD Up studies are ongoing pivotal phase 3, randomized, placebo-controlled, multicenter studies evaluating the safety and efficacy of upadacitinib 15 mg and upadacitinib 30 mg in adolescents and adults with moderate-to-severe AD. Patients were randomized 1 : 1 : 1 to receive oral upadacitinib 15 mg, upadacitinib 30 mg or placebo once daily alone (Measure Up 1 and Measure Up 2) or with concomitant topical corticosteroids (AD Up). At Week 16, patients receiving upadacitinib 15 or 30 mg during the double-blinded period continued their assigned treatment in the blinded extension (BE) period, whereas patients receiving placebo were re-randomized 1 : 1 to receive either upadacitinib 15 or 30 mg in the BE period (upadacitinib treatment for up to 260 weeks). A total of 2693 adults and adolescents (upadacitinib 15 mg, 1340; upadacitinib 30 mg, 1353) who received at least one dose of upadacitinib were included in the integrated analysis. Treatment-emergent adverse events of special interest (AESI) were analysed as exposure-adjusted rates per 100 patient-years (PY) for the entire treatment period to adjust for potentially different durations of follow-up. Upadacitinib was well tolerated by both adults and adolescents. For all patients, rates of AESIs were similar at the 1-year analysis and up to 4-year analysis for upadacitinib (15 mg/30 mg) for: serious infections, 2.3 and 2.2/2.8 and 2.8; opportunistic infections, 1.6 and 1.8/1.9 and 2.4; active tuberculosis, <0.1/<0.1 at both time points; herpes zoster, 3.5 and 3.1/5.2 and 5.8; nonmelanoma skin cancer (NMSC), 0.3 and 0.4/0.4 and 0.3; malignancy excluding NMSC, 0.1 and 0.4/0.5 and 0.3; and adverse events leading to death, 0 and 0/<0.1 and <0.1. Rates of adjudicated major adverse cardiovascular events (MACE) were 0.1 and <0.1/<0.1 and <0.1, and for venous thromboembolic events (VTE) were <0.1 for both doses at the 1-year analysis and up to 4-year analysis. Rates of gastrointestinal perforations were 0 for both doses at both timepoint analyses. Rates of serious infections remain low (<3.0 E/100 PY). Based on the integrated analysis of long-term safety data for up to 4 years, rates of AESIs remained low throughout a longer duration of treatment with upadacitinib 15 or 30 mg among adults and adolescents with moderate-to-severe AD. No new safety risks were observed. Findings of the current safety analysis continue to support a favorable benefit-risk profile of upadacitinib in the treatment of adults and adolescents with moderate-to-severe AD for up to 4 years of treatment.

Early infection risk in patients with systemic lupus erythematosus treated with rituximab or belimumab from the British Isles Lupus Assessment Group Biologics Register (BILAG-BR): a prospective longitudinal study.

Patients with systemic lupus erythematosus (SLE) are at an increased risk of infection relative to the general population. We aimed to describe the frequency and risk factors for serious infections in patients with moderate-to-severe SLE treated with rituximab, belimumab, and standard of care therapies in a large national observational cohort. The British Isles Lupus Assessment Group Biologics Register (BILAG-BR) is a UK-based prospective register of patients with SLE. Patients were recruited by their treating physician as part of their scheduled care from 64 centres across the UK by use of a standardised case report form. Inclusion criteria for the BILAG-BR included age older than 5 years, ability to provide informed consent, a diagnosis of SLE, and starting a new biological therapy within the last 12 months or a new standard of care drug within the last month. The primary outcome for this study was the rate of serious infections within the first 12 months of therapy. Serious infections were defined as those requiring intravenous antibiotic treatment, hospital admission, or resulting in morbidity or death. Infection and mortality data were collected from study centres and further mortality data were collected from the UK Office for National Statistics. The relationship between serious infection and drug type was analysed using a multiple-failure Cox proportional hazards model. Between July 1, 2010, and Feb 23, 2021, 1383 individuals were recruited to the BILAG-BR. 335 patients were excluded from this analysis. The remaining 1048 participants contributed 1002·7 person-years of follow-up and included 746 (71%) participants on rituximab, 119 (11%) participants on belimumab, and 183 (17%) participants on standard of care. The median age of the cohort was 39 years (IQR 30-50), 942 (90%) of 1048 patients were women and 106 (10%) were men. Of the patients with available ethnicity data, 514 (56%) of 911 were White, 169 (19%) were Asian, 161 (18%) were Black, and 67 (7%) were of multiple-mixed or other ethnic backgrounds. 118 serious infections occurred in 76 individuals during the 12-month study period, which included 92 serious infections in 58 individuals on rituximab, eight serious infections in five individuals receiving belimumab, and 18 serious infections in 13 individuals on standard of care. The overall crude incidence rate of serious infection was 117·7 (95% CI 98·3-141·0) per 1000 person-years. Compared with standard of care, the serious infection risk was similar in the rituximab (adjusted hazard ratio [HR] 1·68 [0·60-4·68]) and belimumab groups (1·01 [0·21-4·80]). Across the whole cohort in multivariate analysis, serious infection risk was associated with prednisolone dose (>10 mg; 2·38 [95%CI 1·47-3·84]), hypogammaglobulinaemia (<6 g/L; 2·16 [1·38-3·37]), and multimorbidity (1·45 [1·17-1·80]). Additional concomitant immunosuppressive use appeared to be associated with a reduced risk (0·60 [0·41-0·90]). We found no significant safety signals regarding atypical infections. Six infection-related deaths occurred at a median of 121 days (IQR 60-151) days from cohort entry. In patients with moderate-to-severe SLE, rituximab, belimumab, and standard immunosuppressive therapy have similar serious infection risks. Key risk factors for serious infections included multimorbidity, hypogammaglobulinaemia, and increased glucocorticoid doses. When considering the risk of serious infection, we propose that immunosupppressives, rituximab, and belimumab should be prioritised as mainstay therapies to optimise SLE management and support proactive minimisation of glucocorticoid use. None.

An observational and Mendelian randomisation study on iron status and sepsis

Iron deficiency is associated with a substantial burden of morbidity. However, supplementation of iron has been linked to increased rates of serious infection in randomised trials of children in sub-Saharan Africa. Randomised trials in other settings have been inconclusive and it is unknown if changes in levels of iron biomarkers are linked to sepsis in these other settings. We used genetic variants associated with levels of iron biomarkers as instrumental variables in a Mendelian randomisation (MR) analysis to test the hypothesis that increasing levels of iron biomarkers increase the risk of sepsis. In observational and MR analyses we found that increases in iron biomarkers increase the odds of sepsis. In stratified analyses, we show that this risk may be larger in those with iron deficiency and/or anaemia. Taken together, results here suggest a required caution in supplementation of iron and underline the role of iron homeostasis in severe infection.

A Review on the Safety of Using JAK Inhibitors in Dermatology: Clinical and Laboratory Monitoring.

Janus kinase (JAK) inhibitors are disease-modifying agents with efficacy in treating a spectrum of burdensome dermatologic conditions. The US Food and Drug Administration (FDA) recently placed a black box warning on this class of medications due to safety concerns based on data from studies investigating tofacitinib in patients with rheumatoid arthritis. Here we provide an overview of the timeline of FDA approval of JAK inhibitors in dermatology. We also discuss the available safety profiles of approved oral JAK1 inhibitors, namely abrocitinib and upadacitinib, oral baricitinib, a JAK1/2 inhibitor, deucravacitinib, a Tyk2 inhibitor, and the topical JAK1/2 inhibitor ruxolitinib in dermatology patients. Additionally, we offer suggestions for initial screening and laboratory monitoring for patients receiving JAK inhibitors. We found that the rates of venous thromboembolism reported in trials ranged from no events to 0.1-0.5% in dermatology-specific phase 3 clinical trials compared with no events in the placebo. The rates of cardiovascular events ranged from no events to 0.4-1.2% compared with no events to 0.5-1.2% in the placebo. The rates of serious infections were 0.4-4.8% compared with no events to 0.5-1.3% in the placebo. The rates of nonmelanoma skin cancer (NMSC) ranged from no event to 0.6-0.9% compared with no events in the placebo. The rates of non-NMSC ranged from no event to 0.2-0.7% compared with no event to 0.6% in the placebo. Most patients who developed these adverse events had risk factors for the specific event. The most common adverse events of oral JAK inhibitors included upper respiratory infections, nasopharyngitis, nausea, headache, and acne. Dermatologists should consider patients' baseline risk factors for developing serious complications when prescribing oral JAK inhibitors.

Risk of Infection in Children With Psoriasis Receiving Treatment With Ustekinumab, Etanercept, or Methotrexate Before and After Labeling Expansion

Psoriasis in children is increasingly treated with systemic medications, yet their risk of serious infection is not well characterized in clinical practice. Pediatric clinical trials for these medications were often small and placebo controlled. To estimate the 6-month rate of infections among children with psoriasis who started treatment with ustekinumab, etanercept, or methotrexate. This cohort study used insurance claims data from clinical practices across the US on children aged 17 years or younger with psoriasis who were receiving treatment with a topical medication for psoriasis and started new treatment with ustekinumab, etanercept, or methotrexate. The analysis was stratified by the time before pediatric labeling (2009-2015) and after pediatric approval (2016-2021). Patient follow-up started 1 day after initiating treatment and ended at 6 months. New treatment with ustekinumab, etanercept, and methotrexate. During follow-up, the frequency of inpatient serious infections and outpatient infections requiring treatment was compared. Event rates and rate ratios were estimated after propensity score decile stratification. After exclusions, we identified 2338 patients (1368 girls [57.8%]) who initiated new treatment with a targeted immunomodulating agent. In all, 379 patients started treatment with ustekinumab, 779 patients started treatment with etanercept, and 1180 patients started treatment with methotrexate from 2009 through 2021. The propensity score-adjusted incidence rate of serious infection was 18.4 per 1000 person-years (3 events) for ustekinumab users, 25.6 per 1000 person-years (9 events) for etanercept users, and 14.9 per 1000 person-years (8 events) for methotrexate users. The adjusted rate of outpatient infections was 254.9 per 1000 person-years (39 events) for ustekinumab users, 435.7 per 1000 person-years (139 events) for etanercept users, and 433.6 per 1000 person-years (209 events) for methotrexate users. The adjusted rate ratio of outpatient infections was 0.58 (95% CI, 0.41-0.83) for ustekinumab vs etanercept, 0.66 (95% CI, 0.48-0.91) for ustekinumab vs methotrexate, and 0.95 (95% CI, 0.75-1.21) for etanercept vs methotrexate. Rate ratios were similar during the off-label use era and after pediatric labeling. Among children with psoriasis who started treatment with immunomodulating agents, serious infections were infrequent. This cohort study suggests that there was no increase in the risk of outpatient infections for children who started treatment with ustekinumab compared with etanercept or methotrexate.

P596 Ustekinumab and anti-TNF agents are equally safe and effective in elderly Crohn's disease patients: A propensity adjusted multi-centre cohort study

Abstract Background Anti-tumour necrosis factor (anti-TNF) agents are associated with increased infection risk among elderly inflammatory bowel disease (IBD) patients and thus alternative biologics may be preferable. Previous cohort studies have demonstrated a superior safety profile for vedolizumab compared to anti-TNF agents in the elderly. However, there is limited comparative data on the safety and effectiveness of ustekinumab in elderly IBD patients. We aimed to compare the safety and effectiveness of ustekinumab and anti-TNF agents in elderly Crohn’s disease (CD) patients. Methods Patients ≥60 years old who commenced ustekinumab or an anti-TNF agent for CD were included in this multi-centre retrospective cohort study. The primary outcome was time to development of any infection. Secondary outcomes included incidence of serious infections, defined as requiring hospitalisation and effectiveness assessed by treatment persistence and clinical response rates. We appropriately adjusted for confounders using propensity score matched analysis weighted by the inverse predicted probability of treatment weighting and performed a logistic regression analysis to assess factors associated with infections and treatment persistence. Results 83 patients treated with ustekinumab and 124 patients (30 infliximab and 94 adalimumab) treated with anti-TNF therapy were included. A greater proportion of patients treated with ustekinumab were on concomitant steroids at baseline (37% vs 7.3%, p&amp;lt;0.001). After propensity adjustment, the infection free survival at 12 months was comparable between ustekinumab and anti-TNF agents (HR 0.79, 95% CI 0.58-1.07, p=0.128). Serious infection rate for ustekinumab was 7.55/100 patient years and 5.30/100 for anti-TNFs (p=0.3). None of the variables including Charlson co-morbidity index were associated with infection risk in a multi-variable model. Unadjusted treatment persistence rates at 12 months were lower for ustekinumab compared to anti-TNF agents (68.1% vs 82.8% respectively, p=0.020). After propensity adjustment, there was no difference in treatment persistence at 6 months (OR 1.23, 95% CI 0.37-4.10, p=0.741) and 12 months (OR 1.07, 95% CI 0.45-2.55, p=0.9). There was a significant reduction in HBI at 6 and 12 months compared to baseline in both groups (p&amp;lt;0.001). In a multivariable model, only concomitant thiopurine use was associated with treatment persistence at 12 months (OR 4.6, 95% CI 1.2-30.3, p=0.049). Conclusion We observed comparable safety and effectiveness in a propensity score adjusted comparison of ustekinumab and anti-TNF treated elderly CD patients. The rates of serious infections were comparable between the two groups.

Risk of severe and opportunistic infections and the impact of SARS-COV-2 on this risk in a nationwide cohort of patients with inflammatory bowel disease.

The Inflammatory Bowel Disease (IBD) patients have adopted lifestyle modifications to prevent infection via SARS COV-2. This study aims to examine rate of serious infections and opportunistic infections in the pre-pandemic and pandemic period, and to analyse if the risk associated with medications used to treat IBD were potentially modified by associated change in lifestyle. We conducted a retrospective cohort study of patients from the US national Veteran Affairs Healthcare System (VAHS). Patients were stratified into two groups: pre-pandemic (prior to SARS COV-2 pandemic) and pandemic (during SARS COV-2 pandemic) and outcomes were measured in these groups. Primary outcome was occurrence of any serious infection. Secondary outcome was occurrence of any opportunistic infection. There were 17,202 IBD patients in the pre-pandemic era and 15,903 patients in the pandemic era. The pre-pandemic era had a significantly higher proportion of serious infections relative to the pandemic era (5.1% vs. 4.4%, p=0.002). The proportion of opportunistic infections were similar between pre-pandemic and pandemic eras (0.3% vs. 0.3%, p=0.82). Relative to 5-ASA, patients taking anti-TNF (HR=1.50 (1.31-1.72)), anti-TNF+TP (HR=1.56 (1.24-1.95)) or vedolizumab (HR=1.81 (1.49-2.20)) had an increased hazard of serious infection (p > 0.001). In a nationwide cohort of IBD patients, we found that risk of serious infections could possibly be affected by behavioural modifications due to SARS-COV-2 pandemic.

Ustekinumab and Vedolizumab Are Equally Safe and Effective in Elderly Crohn's Disease Patients.

Anti-tumour necrosis factor (anti-TNF) agents are associated with increased infection risk among elderly inflammatory bowel disease (IBD) patients, and thus, alternative biologics may be preferable. However, little comparative data exist on the safety and efficacy of vedolizumab and ustekinumab in elderly IBD patients. To compare the safety and effectiveness of ustekinumab and vedolizumab in elderly Crohn's disease patients. Patients ≥ 60years old who commenced ustekinumab or vedolizumab for Crohn's disease (CD) were included. Primary outcome was serious infections, defined as requiring hospitalisation. Efficacy was assessed by treatment persistence and clinical response rates. We appropriately adjusted for confounders using propensity score-matched analysis weighted by the inverse predicted probability of treatment weighing and performed a logistic regression analysis to assess factors associated with serious infections and treatment persistence. Eighty-three patients commencing ustekinumab and 42 commencing vedolizumab therapy were included. In a propensity adjusted cohort, the rate of serious infection and treatment persistence were comparable between ustekinumab and vedolizumab. There was a significant reduction in HBI at 6 and 12months compared to baseline in both groups. Male gender was positively associated with serious infection risk at 12months, and penetrating disease behaviour was positively associated with 12-month treatment persistence. Baseline HBI score was negatively associated with 12-month treatment persistence. Cox regression analysis showed no overall difference in treatment discontinuation-free and serious infection-free survival by 12months. We observed comparable safety and effectiveness for ustekinumab and vedolizumab in treating elderly CD patients.

Serious infections in patients with relapsing and progressive forms of multiple sclerosis: A German claims data study

BackgroundPeople with multiple sclerosis (pwMS) have a higher risk of serious infection (i.e., infection-related hospitalizations) than people without MS. Few studies have explored the risk of serious infections by MS phenotype in a real-world setting. This retrospective study compared the incidence of serious infections among people with relapse remitting MS (RRMS), primary progressive MS (PPMS), and secondary progressive MS (SPMS). MethodsAdult pwMS were selected from a German claims database, based on one inpatient or two outpatient diagnoses of MS (ICD-10 G35) by a neurologist from 01/01/2016 to 12/31/2018. Three cohorts (RRMS, PPMS, SPMS) were identified based on codes for MS subtypes included in the German Modification of the ICD-10 system. A fourth cohort of unspecified MS patients combined those with conflicting MS subtype diagnoses and multiple unspecified codes for MS. Serious infections were defined as hospitalizations for which infections were selected as the primary inpatient diagnosis. Infections were identified from a basket of ICD-10 codes distributed across 11 main categories, according to possible pathogen (e.g., other bacterial diseases [A30-A49]) or anatomical location (e.g., urinary tract infection [N39.0]). Multiple infections were counted if an interval of at least 60 days was recorded between episodes. Serious infections were counted from index (i.e., first recorded MS code) until the end of the study period or death. Incidence rates (IRs) were reported per 100 patient years (PY). ResultsA total of 4,250 pwMS (RRMS: 2,307, PPMS: 282, SPMS: 558, unspecified MS: 1,135) were included; 32 patients progressed from RRMS to SPMS during the follow-up period. Mean (SD) age at baseline was 46.6 (13.6), 61.9 (12.4), and 62.5 (11.8) years in patients with RRMS, PPMS, and SPMS, respectively. Most pwMS were female (RRMS 74.8%, PPMS 62.1%, SPMS 67.4%). Progressive pwMS were more likely to have at least 1 comorbidity (PPMS 87.2%, SPMS 87.5%) compared to those with relapsing MS (61.9%). Most RRMS patients received disease-modifying therapy during follow-up (82.1%), while less than half of progressive MS patients did (PPMS 23.8%, SPMS 31.4%). Over a mean (SD) follow-up period of 3.5 (0.8) years, the IR of serious infections per 100 PY was higher in progressive MS cohorts (PPMS 13.5 [11.3–16.1], SPMS 13.6 [12.0–15.3]) than in the RRMS group (3.4 [3.0–3.7]). Yearly IRs remained stable over time in each cohort. Where anatomical location was specified, respiratory (2.0 per 100 PY) and genitourinary (1.9 per 100 PY) infections were most common. Across all subtypes, higher rates of serious infections were observed in men and older patients. ConclusionProgressive MS, older age and male sex are associated with an increased risk of serious infections. Overall, respiratory and genitourinary infections were the most commonly reported serious infections.

Efficacy and Safety of Upadacitinib in Patients with Psoriatic Arthritis: 2-Year Results from the Phase 3 SELECT-PsA 1 Study.

IntroductionEfficacy and safety of the Janus kinase (JAK) inhibitor upadacitinib (UPA) was evaluated in patients with psoriatic arthritis (PsA) through week 104 of the ongoing long-term extension of the phase 3 trial SELECT-PsA 1.MethodsExploratory analyses of all primary and secondary endpoints (non-responder imputation and as observed for binary endpoints; mixed-effect model repeated measures and as observed for continuous endpoints), and summary of treatment-emergent adverse events, in patients receiving UPA 15 mg (UPA15) or 30 mg (UPA30) once daily, or adalimumab 40 mg (ADA) every other week, through week 104 are reported.ResultsOf 1704 patients, 25.4% discontinued the study drug by week 104. Proportions of patients achieving ≥ 20%/50%/70% improvement in American College of Rheumatology criteria (ACR20/50/70), ≥ 75%/90%/100% improvement in Psoriasis Area and Severity Index (PASI75/90/100), or minimal disease activity (MDA) were maintained through week 104; greater responses by nominal P value were observed with UPA15 and UPA30 versus ADA for ACR20/50/70 and MDA. Mean change from baseline in modified total Sharp/van der Heijde Score (mTSS) was similar across groups and to week 56 results. The safety profile of UPA was generally comparable to ADA and not altered from week 56 data. Rates of serious infection, herpes zoster, anemia, neutropenia, lymphopenia, and elevated creatine phosphokinase remained numerically higher with UPA15 and/or UPA30 versus ADA. Rates of malignancies excluding non-melanoma skin cancer (NMSC), major adverse cardiovascular events, and venous thromboembolism were similar across groups; rates of NMSC were higher with UPA versus ADA. Two deaths were reported with UPA15, one with UPA30, and one with ADA.ConclusionsIn PsA patients, efficacy responses were similar or greater with UPA15 or UPA30 versus ADA through week 104, and inhibition of radiographic progression was maintained. No new safety risks were identified with exposure to UPA through 2 years (week 104).Clinical Trial RegistrationClinicalTrials.gov, NCT03104400.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40744-022-00499-w.

Maternal Exposure to Anti-TNF or Thiopurines for IBD Does Not Increase Risk of Early-life Malignancy in Children

Thiopurines and anti–tumor necrosis factor (TNF) are increasingly used during the pregnancy of women with inflammatory bowel disease (IBD). These drugs do not increase the rate of malformations and serious infections in children who have been exposed in utero. Yet, recent large-scale studies have shown that thiopurines are associated with increased rates of stillbirths, preterm births, and large for gestational age infants, whereas combination of thiopurines and anti-TNF is associated with increased rates of serious infections during the first year of life.

Upadacitinib for the Treatment of Rheumatoid Arthritis: An Extensive Review.

To review the characteristics, efficacy, safety, pharmacoeconomics, and place in therapy of upadacitinib, a Janus kinase (JAK) inhibitor, in the treatment of rheumatoid arthritis (RA). PubMed (January 2003-May 2022) was searched using upadacitinib and ABT-494. Human studies published in peer-reviewed publications in English were the primary sources for efficacy and safety data. In randomized, double-blind, controlled clinical studies, upadacitinib demonstrated statistically significant improvement in RA symptoms as monotherapy and in combination with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) when compared with csDMARD monotherapy or to adalimumab or abatacept in combination with csDMARD therapy in patients with RA. American College of Rheumatology 20% response rates were 68% to 79% for upadacitinib monotherapy and 64% to 84% for upadacitinib plus csDMARD therapy, compared with 28% to 59% for csDMARD-only therapy and 63% to 74% for biologic DMARD (bDMARD) plus csDMARD therapy. Long-term extension studies demonstrated similar findings. Upadacitinib had similar rates of serious infections, herpes zoster, major cardiovascular events, and venous thromboembolic events as other JAK inhibitors. Upadacitinib was similar in cost to tofacitinib and twice as high as baricitinib based on current estimated costs to patients, but actual costs may vary. Upadacitinib is an alternative therapy to other JAK inhibitors and bDMARDs in patients with moderate to severe RA who have had an inadequate response to a tumor necrosis factor inhibitor alone or in combination with a csDMARD. Upadacitinib is an effective JAK inhibitor for use in RA.

Risk of Hospitalization for Serious Infection After Initiation of Ustekinumab or Other Biologics in Patients With Psoriasis or Psoriatic Arthritis.

To compare the risk of serious infections requiring hospitalization in patients with psoriasis (PsO) or psoriatic arthritis (PsA) initiating ustekinumab versus other biologics or apremilast. In this multi-database cohort study, we identified patients with PsO/PsA who initiated therapy with adalimumab, apremilast, certolizumab, etanercept, golimumab, ixekizumab, secukinumab, or ustekinumab between 2009 and 2018. The primary outcome measure was hospitalizations due to serious infections, which included bacterial, viral, or opportunistic infections. We estimated hazard ratios (HRs) comparing each study drug to ustekinumab after applying propensity score fine stratification weights for confounding control in each database. Database-specific weighted HRs were combined by meta-analysis. We identified 123,383 patients with PsO/PsA who initiated one of the study drugs. During a total of 117,744 person-years of follow-up, 1,514 serious infections occurred with a crude incidence of 1.29 per 100 person-years. After propensity score fine stratification and weighting, the incidence rates of serious infection among ustekinumab initiators ranged from 0.59 to 0.95 per 100 person-years. Compared with ustekinumab, the combined weighted HRs (95% confidence interval [95% CI]) for serious infections were 1.66 (95% CI 1.34-2.06) for adalimumab, 1.42 (95% CI 1.02-1.96) for apremilast, 1.09 (95% CI 0.68-1.75) for certolizumab, 1.39 (95% CI 1.01-1.90) for etanercept, 1.74 (95% CI 1.00-3.03) for golimumab, 2.92 (95% CI 1.80-4.72) for infliximab, 2.98 (95% CI 1.20-7.41) for ixekizumab, and 1.84 (95% CI 1.24-2.72) for secukinumab. Other biologics and apremilast were associated with a 1.4- to 3-times higher risk of hospitalization for serious infections in PsO/PsA patients when compared to ustekinumab; this finding should be considered in the safety profile of these therapies when selecting appropriate treatment regimens in patients with PsO/PsA.

The Risk of Serious Infections Before and After Anti-TNF Therapy in Inflammatory Bowel Disease: A Retrospective Cohort Study.

Serious infections have been observed in patients with inflammatory bowel disease (IBD) on anti-TNF use-but to what extent these infections are due to anti-TNF or the disease activity per se is hard to disentangle. We aimed to describe how the rates of serious infections change over time both before and after starting anti-TNF in IBD. Inflammatory bowel disease patients naïve to anti-TNF treatment were identified at 5 centers participating in the Swedish IBD Quality Register, and their medical records examined in detail. Serious infections, defined as infections requiring in-patient care, the year before and after the start of anti-TNF treatment were evaluated. Among 980 patients who started their first anti-TNF therapy between 1999 and 2016, the incidence rate of serious infections was 2.19 (95% CI,1.43-3.36) per 100 person years the year before and 2.11 (95% CI, 1.33-3.34) per 100 person years 1 year after treatment start. This corresponded to an incidence rate ratio 1 year after anti-TNF treatment of 0.97 (95% CI, 0.51-1.84). Compared with before anti-TNF therapy, the incidence of serious infection was significantly decreased more than 1 year after treatment (incidence rate ratio 0.56; 95% CI, 0.33-0.95; P = .03). In routine clinical practice in Sweden, the incidence rate of serious infection among IBD patients did not increase with anti-TNF therapy. Instead, serious infections seemed to decrease more than 1 year after initiation of anti-TNF treatment.

Safety of sequential biological therapy in inflammatory bowel disease: results from a tertiary referral centre.

Biologicals represent the cornerstone of treatment for moderate-to-severe inflammatory bowel diseases (IBD). Many patients cycle between biologicals when encountering loss of response or adverse events. To assess the occurrence of serious infections and malignancies with exposure to several (classes of) biologicals. We performed a retrospective cohort study in a tertiary referral centre including consecutive IBD patients exposed to adalimumab, infliximab, ustekinumab or vedolizumab between 1996 and 2019. All serious infections and malignancies, as well as potential confounders, were accounted for. In total, 1575 patients were included with a median (interquartile range) follow-up of 10 (6-16) years and a duration of biological therapy of 71 (39-112) months. Incidence rates of serious infections were 3.4 per 100 patients' years (PY) in the post-biological setting. Serious infections after biological exposure were associated with systemic steroids in monotherapy (hazard ratio 2.96 [95% confidence interval 1.78-4.93], p< 0.0001), combination therapy of systemic steroids and a biological (2.44 [1.37-4.34], p= 0.002), female gender (1.25 [1.04-1.51], p= 0.02), and prior serious infections in the pre-biological setting (1.42 [1.03-1.96], p= 0.03). Malignancy rates were 1.06 per 100PY in the post-biological setting and increased with older age at biological initiation (1.04 [1.02-1.05], p< 0.0001). The risk for serious infections or malignancies was independent of type and number of biologicals to which the patient was exposed. This study shows that the sequential use of biological therapy in IBD does not seem to convey an overall higher risk of serious infections or malignancies, but that underlying more refractory disease seems to increase this risk.

Elderly Patients with Moderate-To-Severe Ulcerative Colitis Are More Likely to Have Treatment Failure and Adverse Outcome

Background and Aim: The aim of this study was to compare therapeutic responses and prognosis between elderly and nonelderly ulcerative colitis (UC) patients with moderate-to-severe activity. Methods: 148 UC patients with moderate-to-severe activity hospitalized between 2000 and 2019 were enrolled consecutively, including 74 patients with the age of diagnosis over 60 years and 74 patients diagnosed less than 60 years. Patients were matched by gender, duration (±15%), disease activity, and admission time (±1 year). They were followed up until the latest medical record or December 2019. The primary outcome was UC-related colectomy or death. Results: 148 patients were followed over median 37.5 months. For steroid use, 76.8% of elderly UC patients were responsive, lower than that in adult group (85.7%). A decreased level of clinical activity index (2.0 [−1.5 to 4.00] vs. 6.0 [3.0–8.0], p < 0.001), reduction of C-reactive protein (23.9 [3.5–65.5] vs. 27.8 [9.7–58.1] mg/L), and erythrocyte sedimentation rate (9.0 [−1.3 to 30.5] vs. 15.5 [3.8–36.5] mm/h) at 4 weeks after steroid induction was less obvious in the elderly. More elderly patients manifested steroid dependence and resistance. 28.4% of elderly UC patients took colectomy, remarkably more than adult patients (12.2%), which also occurred earlier (8.0 [0.5–44.75] vs. 39.5 [12–57.38] months, p = 0.001). Aging (hazard ratio [HR] 2.868, 95% confidence interval [CI]: 1.290–6.375, p = 0.01), male, steroid resistance, and occurrence of complications were independently related to colectomy. The rate of serious infections was significantly higher in the elderly (55.4% vs. 35.1%, p = 0.013), mainly including cytomegalovirus infection, bacterial infection, and extraintestinal infection. Aging (odds ratio [OR] 2.774, 95% CI: 1.355–5.675, p = 0.015), extensive colonic involvement, steroid resistance, and biologics usage were independently associated with a high risk of concomitant infections. Conclusion: Elderly patients with moderate-to-severe UC experienced more treatment failure and increased risk of UC-related colectomy, mortality, and severe infections, predicting demand for more strict and individualized management.
