Background & Aims: We examined treatment patterns and clinical outcomes in a contemporary cohort of children with newly diagnosed inflammatory bowel disease (IBD) in a large, commercially insured U.S. population. Methods: Using the OptumLabs® Data Warehouse, we created an inception cohort of physician-diagnosed IBD in children aged 6–17 years between 2007–23. We examined cumulative incidence of hospitalization, surgery, safety events, and medication use in patients with Crohn's disease (CD) and ulcerative colitis (UC), overall and stratified by diagnostic era, race and ethnicity, sex, and age at diagnosis. Results: Among 787 children with newly diagnosed CD (age at diagnosis, 13.4±2.9y; 57% male; 82% White, 5% Black, 7% Hispanic) followed over mean 4.6±3.0y, 5-year risk of IBD-related hospitalization and major surgery was 30% and 10%, respectively. In children diagnosed in 2019–23, 1-year cumulative use of corticosteroids and advanced therapy was 46% and 75%, respectively; advanced therapy use increased significantly over time (aHR, 3.43 [95% CI, 2.71–4.32] for 2019–23 vs. 2007–12), while corticosteroid use declined (0.67 [0.53–0.84]). Risk of IBD-related hospitalization was lower in children diagnosed between 2019–23 (0.65 [0.43–0.97]) compared with those diagnosed between 2007-12; surgical risk did not decline significantly, with confidence intervals compatible with a clinically meaningful reduction. Among 399 children with newly diagnosed UC (age at diagnosis, 14.0±3.0y; 53% male; 78% White, 5% Black, 7% Hispanic) followed over 4.5±3.0y, 5-year risk of IBD-related hospitalization and colectomy was 36% and 8%, respectively. Advanced therapy use increased significantly over time (4.46 [2.85–6.98] for 2019–23 vs. 2007–12), with no significant change in hospitalization or surgical risk across eras. No consistent racial and ethnic, age, or sex differences in advanced therapy use or clinical outcomes were identified in either CD or UC. Conclusions: In a contemporary cohort of commercially insured children with newly diagnosed IBD, early advanced therapy use has increased markedly over time. Surgical risk did not decline significantly in either disease; however, the study was not powered to exclude a clinically meaningful reduction, and these findings are hypothesis-generating rather than conclusive.

Abstract Introduction Despite regulatory mandates for advanced therapy (AT) washout periods of up to 5 drug half-lives before enrolling patients in inflammatory bowel disease (IBD) trials, the evidence base for these requirements is largely empirical, and whether shorter intervals independently increase the risk of serious infections in real-world practice remains unknown. Methods Using the OptumLabs Data Warehouse, we identified adult patients with IBD who initiated a new AT (tumor necrosis factor antagonists, vedolizumab, interleukin (IL)-12/23 or IL-23 antagonists, or Janus kinase inhibitors) between 2018 and 2023 using a class-specific new-user design. We examined whether exposure to AT within the preceding 12 months (vs no exposure to AT within that window) and timing of discontinuation (≤1 month, 1-<3 months, or 3-12 months) were associated with risk of serious infections using multivariable Cox proportional hazards regression. Results Among 21 564 AT initiators (47 ± 18 years; 52% female; 57% Crohn’s disease), 7490 (34.7%) had AT exposure within the preceding 12 months. Over a mean follow-up of 1.6 ± 0.9 y, 1955 (9.1%) experienced a serious infection. Prior AT exposure was associated with higher infection risk (hazard ratio [HR]: 1.19, 95% confidence interval [CI]: 1.07-1.33), consistent in inverse probability of treatment-weighted analyses (HR, 1.20 [1.06-1.37]). Among patients with prior exposure, timing of discontinuation was not associated with infection risk (HR, 1.17 [0.95-1.43] for ≤1 month vs 3-12 months; HR, 1.01 [0.83-1.22] for 1-<3 months), with no dose–response relationship on continuous modeling. Discussion AT exposure within the preceding 12 months is associated with modestly higher risk of serious infection after initiating a new AT in IBD, but timing of discontinuation does not independently influence this risk.

Abstract Introduction Despite progress in understanding placebo effects in clinical trials of inflammatory bowel disease (IBD), there is a limited understanding of how socioeconomic factors of recruiting countries impact placebo rates. We investigated the association of socioeconomic factors across recruitment sites on placebo rates in IBD randomized controlled trials. Methods We examined the association of clinical and endoscopic remission and response to the weighted Gross National Index (GNI) per capita, Human Development Index (HDI), and out-of-pocket health expenditures as a percentage of current health expenditures (OOP_CHE) of identified trials using mixed effects linear regression. Results Across 76 trials (Crohn’s disease [CD]: n = 32; ulcerative colitis [UC]: n = 44), placebo response rates over time were largely stable, with a small increase across time in clinical remission for CD trials (β = 0.4% per increase in study year, 95% CI: 0.3%-0.84%, P = .04) and a small decrease across time in endoscopic response for UC trials (β = −1.39% per increase in study year, 95% CI: −1.79, −0.99, P < .001). Clinical response was most susceptible to changes in socioeconomic factors in IBD trials (β = −2.96% per 10 000 USD increase in study GNI, 95% CI: −4.98, −0.95%, P = .004; P < .05 for HDI and OOP_CHE). Across both conditions, decreases in clinical response were associated with increases in HDI and OOP_CHE (CD HDI: β = −1.15% per 0.01 increase in study HDI, 95% CI: −2.24, −0.06%, P = .04; UC HDI: β = −0.66% per 0.01 increase in study HDI, 95% CI: −1.19, −0.12%, P = .02). Discussion We found that placebo clinical response was most susceptible to influences of site-level socioeconomic wellbeing. These findings highlight that estimation of placebo rates in trial planning should account for geographic location of recruiting sites.

INTRODUCTION: Safety and effectiveness of treating to target mucosal healing in older patients with Crohn's disease (CD) is unknown. METHODS: We analyzed CD-related complications by 24 months in the randomized evaluation of an algorithm for Crohn's treatment—study 2-2 trial that randomized practices to an enhanced-care or step-care algorithm to determine whether patient age modifies the effect of treatment. Data were analyzed using marginal Cox regression and modified Poisson regression. RESULTS: There was no difference in treatment between younger and older patients in at 24 months. DISCUSSION: Enhanced-care was effective and not associated with increased risk compared with step-care in older patients with CD.

Importance With the availability of multiple classes of advanced therapies for the treatment of Crohn disease (CD), understanding the comparative safety of different therapies can inform treatment positioning. Objective To compare the risk of serious infections, venous thromboembolism (VTE), and major adverse cardiovascular events (MACE) with different advanced therapies in patients with CD. Design, Setting, and Participants This retrospective comparative effectiveness research study was conducted between January 1, 2016, and December 31, 2022, with a mean (SD) follow-up of 26.9 (2.4) months until July 1, 2024. Using an administrative claims database (OptumLabs Data Warehouse), commercially insured patients with CD, who initiated treatment with tumor necrosis factor-α (TNF) antagonists, anti-integrin agents (vedolizumab), interleukin (IL)-12/23p40 antagonists (ustekinumab), IL-23p19 antagonists (primarily risankizumab), or Janus kinase inhibitors (upadacitinib) between 2016 and 2022 and had follow-up for at least 1 year before and after treatment initiation, were included. Exposure TNF antagonists vs anti-integrin agents (vedolizumab) vs IL-12/23p40 antagonists (ustekinumab) vs IL-23p19 antagonists (risankizumab) vs Janus kinase inhibitors (upadacitinib). Main Outcomes and Measures The risk of serious infections, VTE, and MACE was compared with various advanced therapies through multinomial propensity score-based inverse probability treatment weighting, with propensity scores estimated through generalized boosted models, accounting for disease characteristics, health care utilization, comorbidities, and prior and concomitant medications, and through competing risk of mortality. Cause-specific hazard ratios (HRs) and 95% CIs for multiple treatment comparisons were calculated. Results This study included 12 245 patients with CD (mean [SD] age, 46.5 [17.5] years; 6642 females [54.2%]), who were treated with TNF antagonists (n = 5274), vedolizumab (n = 2716), ustekinumab (n = 3544), risankizumab (n = 559), or upadacitinib (n = 152). Serious infection incidence rates ranged from 5.46 (95% CI, 4.86-6.07) to 9.02 (95% CI, 6.38-11.89) per 100 person-years across therapies. After adjusting for confounding variables, there were no statistically significant differences in the risk of serious infections across different agents, including between risankizumab and ustekinumab (HR, 1.14 [95% CI, 0.78-1.67]), risankizumab and TNF antagonists (HR, 1.00 [95% CI, 0.68-1.47]), or ustekinumab and TNF antagonists (HR, 0.88 [95% CI, 0.74-1.04]). The incidence of VTE (incidence rate, 0.90 [95% CI, 0.71-1.10] to 2.33 [95% CI, 1.06-3.82] per 100 person-years) and MACE (0.68 [95% CI, 0.51-0.85] to 1.49 [95% CI, 0.43-2.76] per 100 person-years) was low, without any significant differences across agents. Conclusions and Relevance In this comparative effectiveness research study of patients with CD, no significant differences in the risks of serious infections, VTE, or MACE across various advanced therapies were found. These findings support clinical decision-making on choice of advanced therapies for most individual patients with CD to be driven primarily by comparative treatment effectiveness rather than driven by concerns of serious adverse events.

INTRODUCTION: We conducted a retrospective cohort study comparing the safety of advanced therapies in patients with ulcerative colitis (UC). METHODS: Using an administrative claims database (OptumLabs Data Warehouse), we identified patients with UC who initiated treatment with tumor necrosis factor-α (TNF) antagonists, anti-integrin agents, anti-interleukin, Janus kinase inhibitors (JAK), or sphingosine-1 phosphate receptor modulators between 2016 and 2022 and had followed up for at least 1 year before and after treatment initiation. We compared the risk of serious infections, venous thromboembolism, and major adverse cardiovascular events through multinomial propensity score-based inverse probability weighting, with propensity scores estimated through generalized boosted models that accounted for disease characteristics, healthcare utilization, comorbidities, and previous and concomitant medications, and the competing risk of mortality. We calculated cause-specific hazard ratios (HR) and 95% confidence intervals for multiple treatment comparisons. RESULTS: We included 9,430 patients with UC treated with TNF antagonists (n = 4,111), anti-integrins (n = 3,165), anti-ILs (n = 1,342), JAK inhibitors (n = 701), or sphingosine-1 phosphate receptor modulators (n = 111), followed over median 27 months. After adjusting for confounding variables, anti-ILs were associated with a lower risk of serious infections compared with TNF antagonists (HR, 0.66 [95% confidence interval, 0.51–0.87]) and anti-integrins (HR, 0.75 [0.57–0.98]). JAK inhibitors were associated with a lower risk of serious infections compared with TNF antagonists (HR, 0.66 [0.46–0.94]). The incidence of venous thromboembolism (incidence rate, 1.4–2.0 per 100 py) and major adverse cardiovascular event (0.5–1.0 per 100 py) was very low, without any significant differences across agents. DISCUSSION: In a real-world cohort of patients with UC, anti-ILs and JAK inhibitors were associated with a lower risk of serious infections and may offer net benefit, especially in patients with previous TNF antagonist exposure.

Abstract Background and Aims Seven new advanced therapies, belonging to three new classes, have been approved for the treatment of inflammatory bowel diseases (IBD) since 2021. We examined trends in utilization of advanced therapies in the USA since 2021. Methods Using de-identified electronic health record data from 71 US health systems, we examined quarterly trends in utilization of different advanced therapies in patients with ulcerative colitis and Crohn’s disease between 2021 and 2025, using interrupted time-series analysis utilizing Prais–Winsten regression. Results In 11 093 patients with ulcerative colitis treated with advanced therapies, we observed an increase in use of upadacitinib (12.1% in Q2/2025; P < .001, compared with first quarter of prescription), interleukin-23p19 (IL23p19) antagonists (5.5%; P = .03), and ustekinumab (9.5%; P = .04), decline in use of tumor necrosis factor (TNF) antagonists (34.5%; P = .003), and stable use of vedolizumab (33.6%; P = .17) and sphingosine-1 phosphate receptor modulators (1.6%; P = .28). In 15 951 patients with Crohn’s disease treated with advanced therapies, we observed an increase in use of IL23p19 antagonists (15.0% in Q1/2025; P = .003) and upadacitinib (5.9%; P < .001) and decline in use of TNF antagonists (50.2%; P = .001) and ustekinumab (13.5%; P < .001). Conclusions Contemporary trends in advanced therapy utilization in patients with IBD suggest an increased utilization of upadacitinib and anti-interleukins, accompanied by a decline in use of TNF antagonists in the USA.

ABSTRACT Background Advanced therapies increase the risk of shingles in inflammatory bowel diseases (IBD). Aim To compare the risk of shingles with different advanced therapies in patients with IBD. Methods We identified patients with IBD who initiated treatment with tumour necrosis factor (TNF) antagonists, anti‐integrins, anti‐interleukins, Janus kinase (JAK) inhibitors, or sphingosine‐1 phosphate receptor (S1PR) modulators between 2016 and 2022 and had follow‐up for at least 1 year before and after treatment initiation. We estimated the incidence rate (IR per 100 person‐year [PY]) of shingles (overall and complicated) and compared the risk with different advanced therapies through multinomial propensity score‐based inverse probability of treatment weighting (IPTW), with propensity scores estimated through generalised boosted models, accounting for disease characteristics, healthcare utilisation, comorbidities and prior and concomitant medications. Weighted Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for multiple treatment comparisons. Results We included 21,675 patients followed over 27 months. IRs per 100 PY of shingles and complicated shingles were: TNF antagonists 1.0/0.3, anti‐integrin agents 1.4/0.4, anti‐interleukins 1.2/0.5, JAK inhibitors 3.3/0.9 and S1PR modulators 2.0/1.0. After adjusting for confounding variables, JAK inhibitors were associated with higher risks of shingles than TNF antagonists (HR 2.19; 1.28–3.75), anti‐integrins (HR 1.87; 1.12–3.14) and anti‐interleukins (HR 1.70; 0.98–2.96). Conclusions JAK inhibitors were associated with 1.7–2.2‐fold higher risk of shingles than other advanced therapies.
