Patients in the liso-cel plus ibrutinib cohort of the phase 1/2, open-label TRANSCEND CLL 004 study had relapsed/refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) and received liso-cel (50×106 [dose level (DL)1] or 100×106 [DL2] chimeric antigen receptor-positive T cells) with concurrent ibrutinib from enrollment through 90 days after liso-cel infusion or longer per investigator discretion. Primary end point was complete response/remission (CR)/CR with incomplete marrow recovery (CRi) by investigator assessment. Among 56 patients who received ibrutinib plus liso-cel (DL1, n=5; DL2, n=51), median (range) age was 64.5 years (44‒77), 98% had high-risk cytogenetics, 55% had progression on Bruton tyrosine kinase inhibitor and venetoclax failure, and median (range) number of prior therapies was 5 (1‒13). Median (range) follow-up was 24.8 months (3.1‒51.8). At DL2, CR/CRi rate was 45% (95% confidence interval [CI], 31‒60) and overall response rate was 86% (95% CI, 74‒94). Median (95% CI) duration of response was not reached (NR; 28.7‒NR) for patients with CR/CRi and 41.4 months (23.3‒NR) for all responders. Median (95% CI) progression-free survival was 31.4 months (20.1‒NR). In DL1+DL2, most common grade ≥3 treatment-emergent adverse events (TEAE) were neutropenia (52%) and anemia (41%). Cytokine release syndrome was reported in 80% of patients (grade 3, 4%; no grade 4/5), and neurological events in 41% (grade 3/4, 11%; no grade 5). Ibrutinib-related TEAEs were reported in 68% of patients (grade 3/4, 43%; no grade 5). Liso-cel plus ibrutinib demonstrated notable efficacy in patients with relapsed/refractory CLL/SLL with predictable and manageable safety. Clinicaltrials.gov: NCT03331198; NCT03435796.

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.

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 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.

7037 Background: TRANSCEND CLL 004 (NCT03331198) is a phase 1/2, open-label, nonrandomized, multicohort study in adult patients (pt) with R/R chronic lymphocytic leukemia/small lymphocytic lymphoma with liso-cel mono and liso-cel + ibrutinib combo cohorts. Given the study design, we performed PS matching/weighting to adjust for differences in key covariates between cohorts to compare efficacy and safety. Methods: Here, PS is the probability of receiving combo given the covariates and estimated by logistic regression. Covariates were hemoglobin, LDH, number of prior therapies, platelets, prior BTKi + venetoclax exposure, R/R on prior BTKi, and bulky disease for efficacy; and ALC, bulky disease, CRP, ferritin, and number of prior therapies for safety. PS balancing methods were optimal 1:1 matching, average treatment effect for treated pts (ATT) full matching, and ATT inverse probability of treatment weighting (IPTW). Efficacy endpoints were response (CR rate, ORR) and time to event endpoints (DOR, PFS, OS). Safety endpoints were proportions of pts with any-grade (gr)/gr ≥ 3 cytokine release syndrome (CRS) and investigator-identified neurological events (NE). Results: Fifty-one and 88 efficacy-evaluable pts were treated at dose level 2 (100 × 10 6 CAR + T cells) in the combo and mono cohorts, respectively. Before matching/weighting on PS, odds of achieving CR and overall response were statistically significantly higher for combo (Table). DOR did not differ between cohorts. For PFS and OS, HRs were lower with combo vs mono (not statistically significant [NS]). Odds of gr ≥ 3 CRS/NE were lower with combo vs mono (NS). After matching/weighting, odds of CR (except IPTW ATT) and overall response remained statistically significantly higher in combo. HRs for PFS and OS and ORs for gr ≥ 3 CRS/NE were numerically lower with combo vs mono (NS, except IPTW ATT for PFS). HRs for DOR were less but close to HR of 1. Conclusions: The liso-cel + ibrutinib combo demonstrated a trend for better efficacy and safety vs liso-cel mono, with statistically significant differences for CR rate and ORR.

Introduction Targeted immunomodulators (eg, advanced therapies) effectively achieve symptomatic remission in patients with inflammatory bowel disease (IBD). However, ~25%–50% of patients with IBD achieving symptomatic remission with an advanced therapy may have continued endoscopically/radiologically active bowel inflammation, and it is uncertain whether changing alternative advanced therapies in asymptomatic patients with IBD will reduce bowel inflammation and achieve durable deep remission. Methods and analysis The QUality Outcomes Treating IBD to Target (QUOTIENT) study is an open-label, multicentre, pragmatic, randomised, controlled trial that aims to compare the efficacy and safety of switching to an alternative advanced therapy targeting endoscopic/radiological remission (treat-to-target) versus continuing the initial, or index, advanced therapy, in asymptomatic patients with IBD with moderate-to-severe endoscopic/radiological bowel inflammation. Enrolment is planned for ~250 participants in Canada/USA, randomised 1:1 to switching to alternative advanced therapy or continuing index advanced therapy, and then followed 104 weeks within routine clinical practice. Patient-reported outcomes measure efficacy and quality of life/treatment burden/safety. Primary endpoint is the time from randomisation to treatment failure. Ethics and dissemination The study is conducted in compliance with the protocol, ICH Good Clinical Practice, applicable regulatory requirements and appropriate review boards/independent ethics committees (approval numbers: Pro00077486; Pro00061437; STUDY00002062; 22-004171; i22-01269; IRB22-0890; IRB_00154397; 2000032384; SHIRB#2022.095-2; STUDY00007146; MMC#2024-18; REB#125290; 17784; Pro00142214; 20240660-01H), with documented written informed consent. Findings will be disseminated through peer-reviewed journals, scientific presentations, and publicly available Patient-Centered Outcomes Research Institute (PCORI) websites, including lay summaries. The Crohn’s & Colitis Foundation Education, Support, and Advocacy Department, and our patient advocacy stakeholder, will develop educational and marketing resources to communicate findings to a broad audience (>250 000 patients/caregivers/healthcare professionals). Trial registration number NCT05230173 .

Data indicate that earlier initiation of anti-tumor necrosis factor alpha (anti-TNF-α) biologic medicines may prevent progression to irreversible bowel damage and improve outcomes for patients with inflammatory bowel disease (IBD), particularly Crohn’s disease. However, the high cost of such therapies may restrict access and prevent timely treatment of IBD. Biosimilar anti-TNF-α medicines may represent a valuable opportunity for cost savings and optimized patient outcomes by improving access to advanced therapies and allowing earlier anti-TNF-α treatment initiation. Biosimilar anti-TNF-α medicines have been shown to offer consistent therapeutic outcomes to their reference medicines, yet despite entering the IBD treatment armamentarium over 10 years ago, their implementation in clinical practice remains suboptimal. Factors limiting the ‘real’ use of biosimilar anti-TNF-α medicines may include an ongoing lack of understanding and acceptance of biosimilars by both healthcare professionals (HCPs) and patients, as well as systemic factors such as formulary decisions outside of the control of the prescriber. In this review, an expert panel of gastroenterologists discusses HCP-level considerations to improve biosimilar anti-TNF-α utilization in IBD in order to support early anti-TNF-α initiation and maximize patient outcomes.

Abstract Asthma is a heterogeneous disease with variable presentation and characteristics. There is a critical need to identify underlying molecular endotypes of asthma. We performed the largest transcriptomic analysis of 808 bronchial epithelial cell samples across 11 independent cohorts, including 3 cohorts from the Severe Asthma Research Program. Using seven datasets (218 patients with asthma, 148 healthy control subjects) as discovery cohorts, we identified 505 differentially expressed genes, which we validated in the remaining four datasets. Unsupervised clustering using the 505 differentially expressed genes identified four reproducible clusters of patients with asthma across all datasets, corresponding to healthy control subjects, patients with mild/moderate asthma, and patients with severe asthma with significant differences in several clinical markers of severity, including pulmonary function, Type 2 inflammation, fractional exhaled nitric oxide, and maximum bronchodilator reversibility. Importantly, we found the same clusters in pediatric patients using nasal lavage fluid cells, demonstrating the gene signature and clusters are not confounded by age and are conserved in both lower and upper airways. The four asthma clusters may represent a unifying framework for understanding the molecular heterogeneity of asthma. Further study could potentially enable a precision medicine approach of matching therapies with patients with asthma most likely to benefit.
