AbstractBackgroundPYRAMID was an international post‐marketing registry that aimed to collect data on the long‐term safety and effectiveness of adalimumab treatment per local standard of care in patients with moderately to severely active Crohn's disease (CD). Here, we present post hoc analyses of observational data from patients who became pregnant while participating in this registry and receiving adalimumab.MethodsFrom the subpopulation of patients receiving adalimumab who became pregnant while taking part in PYRAMID, data on patient characteristics, pregnancy outcomes, and complications of pregnancy were analysed retrospectively.ResultsAcross the PYRAMID registry, 293 pregnancies occurred in patients who had gestational adalimumab exposure (average disease duration at last menstrual period: 8.6 years), resulting in 300 pregnancy outcomes. A total of 197 pregnancies (67.2%) were exposed to adalimumab in all trimesters per physician's decision. Of the known reported outcomes (96.3%), 81.7% (236/289) were live births, 10.4% (30/289) were spontaneous abortions, 4.8% (14/289) elective terminations, 2.8% (8/289) ectopic pregnancies, and 0.3% (1/289) was a stillbirth. Congenital malformations (pulmonary valve stenosis and tricuspid valve incompetence) were reported in one infant. In addition to the pregnancy outcomes described above, 23 complications of pregnancy were reported in 20 patients.ConclusionsThis analysis showed that adalimumab treatment in patients with CD, who became pregnant whilst participating in the PYRAMID registry, contributed no additional adverse effects during the pregnancy course or on pregnancy outcomes.

Abstract Background Upadacitinib (UPA), an oral selective and reversible JAK inhibitor, demonstrated significantly greater efficacy compared with placebo (PBO) for induction of remission in patients with moderately to severely active ulcerative colitis (UC) in two phase 3 induction trials. Aims Evaluate safety and efficacy of 52 weeks of UPA 15 mg QD (UPA15) and 30mg QD (UPA30) compared to placebo in patients achieving clinical response following UPA 45 mg treatment in the induction trials. Methods The primary analysis (n=451) evaluated efficacy and safety of UPA15 and UPA30 compared to PBO as maintenance therapy. The primary endpoint was clinical remission via adapted Mayo score at wk 52. Ranked secondary endpoints included endoscopic improvement, maintenance of clinical remission, corticosteroid-free clinical remission, maintenance of endoscopic improvement, endoscopic remission, maintenance of clinical response and Histologic-endoscopic mucosal improvement (HEMI). Results Baseline characteristics were similar between all treatment groups. Both UPA15 and UPA30 met the primary endpoint, and all secondary endpoints. Significantly greater percentages of patients receiving UPA15 and UPA30 vs. PBO achieved clinical remission (42.3% and 51.7%, vs. 12.1%), endoscopic improvement (48.7% and 61.6%, vs. 14.5%), maintenance of clinical remission (59.2% and 69.7%, vs. 22.2%), corticosteroid-free clinical remission (57.1% and 68.0%, vs. 22.2%), maintenance of endoscopic improvement (61.6% and 69.5%, vs. 18.9%), endoscopic remission, (24.2% and 25.9%, vs. 5.6%) and HEMI (34.8% and 49.3%, vs. 11.8%) (p<0.001 for all endpoints). UPA15 and UPA30 were both well-tolerated and no new safety signals were observed. Rates for serious adverse events (AEs) and AEs leading to treatment discontinuation were similar between UPA15 and UPA30 groups and lower compared to the PBO group. Most common AEs were nasopharyngitis and creatine phosphokinase elevation among UPA groups and UC exacerbation within the PBO group (30.2%). Herpes zoster was only reported in UPA groups (3.9%-4.1%). Similar rates of malignancy excluding NMSC were seen within all groups (0.7%-1.3%). MACE were only reported among patients receiving PBO (0.7%), while VTE were only found with UPA30 (1.3%). Conclusions In patients responding to UPA induction therapy, both UPA15 and UPA30 were safe and effective as maintenance treatment at 52 wk for all primary and secondary endpoints. Patients receiving UPA30 responded approximately 10% better for most endpoints compared to those receiving UPA15. Both doses were well-tolerated, with no new safety signals observed.

BACKGROUND: Ozanimod, an oral sphingosine 1-phosphate (S1P) receptor modulator selectively targeting S1P 1 and S1P 5 , demonstrated superior efficacy and safety vs placebo for up to 52 weeks in adults with moderately to severely active ulcerative colitis (UC) in a phase 3 study (True North). In this post-hoc analysis, we evaluated the impact of prior biologic exposure on response to ozanimod. METHODS: True North consisted of two cohorts. In cohort 1, patients with UC received double-blind treatment with once-daily ozanimod 0.92 mg (equivalent to ozanimod HCl 1 mg) or placebo. In cohort 2, patients received open-label once daily ozanimod 0.92 mg. Ozanimod responders after a 10-week induction were re-randomized to double-blind maintenance with ozanimod 0.92 mg or placebo through week 52. Outcomes based on prior biologic exposure (biologic-naïve, 1 biologic, and 2+ biologics) and prior biologic type (anti-tumor necrosis factor [TNF] agents, vedolizumab, or both) were analyzed for clinical remission, clinical response, endoscopic improvement, and mucosal healing. Patients exposed to only a JAK inhibitor were excluded from the analysis. RESULTS: A total of 992 patients (n = 213 placebo and n = 426 ozanimod in cohort 1, n = 353 ozanimod in cohort 2) were included in the analysis for induction; 616 were biologic-naïve, 162 had exposure to 1 biologic, and 214 were exposed to 2 or more biologics. At baseline, biologic-exposed patients had more prior corticosteroid use, longer disease duration, and more extensive disease than biologic-naïve patients. During induction, greater therapeutic effects of ozanimod were generally seen in biologic-naïve vs biologic-exposed patients, and ozanimod-treated patients had greater responses on nearly all reported endpoints at week 10 (cohort 1). Clinical remission was achieved in 23% vs 6.6% of patients on ozanimod vs placebo who were biologic naïve, 17.2% vs 8.3% on 1 prior biologic, and 3.7% vs 2.5% on 2 or more biologics. Clinical response was reached in 53% vs 28% of patients on ozanimod vs placebo who were biologic naïve, 50% vs 33% on 1 biologic, and 27% vs 15% on 2 or more biologics. During maintenance, ozanimod-treated patients had greater responses on all endpoints versus placebo, with similar proportions of patients achieving clinical response to ozanimod regardless of prior biologic exposure (61% for biologic naïve, 60% for 1 biologic, and 55% for 2 or more biologics). At week 52, the proportion of patients on ozanimod with clinical remission was similar in the 1-biologic and 2+-biologic exposure groups (28% and 26%, respectively), and proportions of patients on ozanimod with endoscopic improvement and mucosal healing were similar for the 1-biologic and biologic-naïve groups (47% and 50%, 30%, and 33%, respectively). Among patients with inadequate response to prior anti-TNF agents, vedolizumab, or both at baseline, treatment effects favored ozanimod vs placebo on these endpoints in all three groups during both induction and maintenance. CONCLUSION: Ozanimod improved clinical, endoscopic, and histologic outcomes in both biologic-exposed and -naïve patients. Patients with prior biologic use may require additional time to respond to treatment. Outcomes were improved with ozanimod regardless of prior use of anti-TNF agents and vedolizumab.

Abstract Background and Aims Patient-reported outcomes are recommended endpoints in Crohn’s disease [CD] trials. The association between patient-reported general well-being relative to symptoms of diarrhoea and abdominal pain [AP] in patients with moderate to severe CD was explored. Methods Patients from three randomized, placebo-controlled, double-blind adalimumab or upadacitinib studies with average daily very soft/liquid stool frequency [SF] ≥4 and/or AP score ≥2 at baseline were included. Using electronic diaries, patients reported general well-being [seven-point Likert scale; 1 = worst; 7 = best] in item 10 of the Inflammatory Bowel Disease Questionnaire [IBDQ]. Changes in well-being and clinical outcomes of SF and AP from baseline to week 12 or 16, and the relationship between well-being and clinical outcomes were evaluated using cumulative distribution function and probability density function curves. Results In total, 858 patients with CD were included [adalimumab, n = 695; upadacitinib, n = 163]. Patients who achieved clinical remission [SF ≤2.8, AP score ≤1.0, neither worse than baseline] were more likely than those not in clinical remission to report IBDQ item 10 response in the 6–7 group category but not IBDQ categories ≤5. Higher IBDQ score for item 10 [6–7] was associated with lower SF and AP score. Greater point increases in IBDQ item 10 were associated with a greater percentage decrease in clinical parameters; a ≥25–30% decrease in SF or AP was associated with a ≥1-point improvement in IBDQ. Conclusions An association between improvements in patient-reported general well-being and clinical remission/response was observed using outcomes of SF and AP, supporting the clinical remission/response endpoint definitions used in clinical studies of CD.

Abstract Background and Aims To report results from VISIBLE 2, a randomised, double-blind, placebo-controlled, phase 3 trial evaluating a new subcutaneous [SC] vedolizumab formulation as maintenance treatment in adults with moderately to severely active Crohn’s disease [CD]. Methods Following open-label vedolizumab 300 mg intravenous induction therapy at Weeks 0 and 2, Week 6 clinical responders (≥70-point decrease in CD Activity Index [CDAI] score from baseline) were randomised 2:1 to receive double-blind maintenance vedolizumab 108 mg SC or placebo every 2 weeks until Week 50. Assessments at Week 52 included clinical remission [primary endpoint; CDAI ≤150], enhanced clinical response [≥100-point decrease in CDAI from baseline], corticosteroid-free clinical remission among patients using a corticosteroid at baseline, clinical remission in anti-tumour necrosis factor [anti-TNF]-naïve patients, and safety. Results Following vedolizumab intravenous induction, 275 patients were randomised to vedolizumab SC and 135 to placebo maintenance. At Week 52, 48.0% of patients receiving vedolizumab SC versus 34.3% receiving placebo were in clinical remission [p = 0.008]. Enhanced clinical response at Week 52 was achieved by 52.0% versus 44.8% of patients receiving vedolizumab SC versus placebo, respectively [p = 0.167]. At Week 52, 45.3% and 18.2% of patients receiving vedolizumab SC and placebo, respectively, were in corticosteroid-free clinical remission, and 48.6% of anti-TNF-naïve patients receiving vedolizumab SC and 42.9% receiving placebo were in clinical remission. Injection site reaction was the only new safety finding observed for vedolizumab SC [2.9%]. Conclusions Vedolizumab SC is an effective and safe maintenance therapy in patients with CD who responded to two infusions of vedolizumab intravenous induction therapy.

Abstract Background Vedolizumab (VDZ), an anti-a4β7 integrin antibody that selectively blocks lymphocyte trafficking to the gut, is approved for the treatment of adult patients with moderate-to-severe Crohn’s disease (CD). This post hoc analysis of data from the VISIBLE 2 trial evaluated early patient-reported outcomes assessed within the first 14 days of VDZ induction. Methods VISIBLE 2 (NCT02611817; EudraCT 2015-000481-58) was a phase 3, multicentre, placebo-controlled study, evaluating the efficacy and safety of subcutaneous VDZ for maintenance treatment in patients with moderately to severely active CD. Efficacy was assessed based on CD Activity Index (CDAI). Patients received induction treatment with intravenous (IV) VDZ 300 mg open-label at Weeks 0 and 2. For this analysis, responses to VDZ were assessed using CDAI sub-scores for patient-reported abdominal pain (AP) and stool frequency (SF) collected daily via electronic diary in the first 14 days of VDZ treatment (Day 1 to 15) in all patients receiving ≥1 VDZ dose at induction. Descriptive statistics were used. Results The analysis included 611 patients (mean [SD] age 37.6 [13.4] years; CD duration 9.0 [8.1] years); 323 (53%) were male; 228 (37%) had severe disease (CDAI >330) at baseline; and 350 (57%) were anti-TNF-experienced. In the first 14 days of VDZ IV induction, the rate of patients with daily SF≤3 increased from 30% at baseline (Day 1) to 47.7% on Day 15. Increases were similar in both anti-TNF-naïve vs. anti-TNF-experienced patients and in patients with severe vs. moderate disease (Figure 1). Mean baseline SF was reduced from 6.4 to 5.0 at Day 15 in patients with severe disease and from 4.3 to 3.5 in patients with moderate disease. Overall, the proportion of patients rating AP as severe/moderate declined from baseline to Day 15 of induction (from 14.6% to 8.2% for severe AP and from 60.7% to 40.6% for moderate AP). Similar Day 1-to-15 reductions were reported in both anti-TNF-naïve (severe AP: 14.2% to 9.2%; moderate AP: 62.6% to 44.6%) and anti-TNF-experienced patients (severe AP: 14.8% to 7.4%; moderate AP: 59.3% to 37.7%), respectively. Although a minority of patients (6.3%) in the sub-group with moderate AP at baseline had worse pain at Day 15, there were early improvements in AP ratings for most patients reporting severe or moderate AP at baseline (Figure 2). Conclusion This post hoc analysis of daily patient-reported SF and AP in the VISIBLE 2 CD study indicates an early onset of response to VDZ IV induction within the first 14 days of treatment.

Abstract Background Upadacitinib (UPA) is a selective and reversible Janus kinase inhibitor.U-ACCOMPLISH is one of two phase 3 induction trials that evaluated the safety and efficacy of UPA 45 mg once daily (QD) in adults with ulcerative colitis (UC). Methods U-ACCOMPLISH was a multicentre, randomized, double-blind, placebo-controlled trial (NCT03653026) that enrolled patients with moderate-to-severe UC (defined as adapted Mayo score 5–9 with centrally read endoscopic score 2–3) who had inadequate response, loss of response, or intolerance to aminosalicylates, immunosuppressants, corticosteroids and/or biologics. Patients were randomized 2:1 to UPA 45 mg QD or placebo (PBO) for 8 weeks. At week 8, responders entered the maintenance phase and non-responders entered the extended treatment period to receive open-label UPA 45 mg QD for additional 8 weeks.The primary endpoint (clinical remission per adapted Mayo Score) and ranked secondary endpoints including symptomatic, endoscopic– histologic evaluations from the 8-week PBO-controlled period are reported here. Non-responder imputation incorporating multiple imputation for missing data due to COVID-19 are reported. Results 522 patients were randomized (UPA, n=345; PBO, n=177); the intent-to-treat population included 341 patients in UPA and 174 patients in PBO group. Baseline demographics and disease characteristics were similar between groups; 50.7% and 51.1% were biologic inadequate responders in UPA and PBO groups, respectively (Table 1). A significantly higher proportion of patients receiving UPA 45 mg QD (33.5%) versus PBO (4.1%) achieved the primary endpoint (adjusted treatment difference: 29.0% [23.2, 34.7]; P<0.001). A significantly higher proportion of patients receiving UPA versus PBO also achieved all ranked secondary endpoints (all P<0.001; Figure 1).Serious adverse events were reported by 3.2% and 4.5% of patients in UPA and PBO groups, respectively (Table 2). Similar rates of serious infection were observed in both groups (0.6%); 2 events each of herpes zoster and opportunistic infection were reported in UPA group. No active tuberculosis, malignancy, adjudicated major adverse cardiovascular events, or deaths were reported in the study. One patient with venous thromboembolism (deep vein thrombosis and pulmonary embolism) and 1 patient with gastrointestinal perforation were reported in the placebo group. Conclusion In U-ACCOMPLISH, 8-week UPA 45 mg QD induction treatment led to statistically significant improvements in clinical, endoscopic, and combined endoscopic-histologic endpoints. The treatment was well tolerated, and the safety profile and AE prevalence was comparable with previous studies of UPA with no new safety signals identified.
