Abstract Background Adalimumab (ADA) is efficacious and well tolerated in adult patients with ulcerative colitis (UC).1,2 SERENE-UC (NCT02065622) is a study evaluating higher ADA dosing regimens from which induction study results have previously been reported3; here, we report data from the maintenance study. Methods This Phase 3, double-blind, randomised, multicentre study evaluated higher vs. standard ADA dosing regimens for induction and maintenance therapy in adult patients with moderately to severely active UC. Following completion of the induction study at Week 8, all patients were re-randomised 2:2:1 to ADA 40 mg every week (40 EW), ADA 40 mg every other week (40 EOW), or exploratory ADA 40 mg with therapeutic drug monitoring (TDM) regimens, stratified by induction treatment regimen, clinical response status at Week 8, and clinical remission (CRem) status at Week 8 among Week 8 responders. Efficacy endpoints were evaluated in Week 8 responders (ITT-RP) unless indicated differently. The primary efficacy endpoint was proportion of patients achieving CRem (full Mayo Score ≤2 with no subscore >1) at Week 52. The endoscopic component of the Mayo Score was scored via central reading. Non-responder imputation was used for missing values. Comparisons between 40 EW and 40 EOW dosing regimens used the Cochran–Mantel–Haenszel test adjusted for stratification. Safety assessment included a collection of adverse events (AEs), vital signs, and laboratory data. Results Of 852 patients in the Global (ex-Japan) induction study, 757 were re-randomised at Week 8 and 371 were included in the ITT-RP. In the ITT-RP, induction baseline demographics and disease characteristics were generally balanced across the 3 treatment arms; range across arms for mean UC disease duration was 6.2–7.8 years, 6.8–11.7% had prior infliximab use, and 62.5–63.5% were receiving corticosteroids. The overall mean ADA exposure was 252.2 days. The table displays results for efficacy endpoints. The observed safety profile was similar between maintenance treatment arms, including AEs of special interest (generally <1% across arms). Conclusion In the Global (ex-Japan) study of SERENE-UC, CRem at Week 52 was numerically higher among Week 8 responders in patients receiving ADA 40 EW compared with 40 EOW maintenance regimens (∆ = 10.5%), but not statistically significant. Higher maintenance treatment with 40 EW was generally safe and well tolerated with a similar safety profile to 40 EOW. No new long-term safety concerns were observed. References

INTRODUCTION: An unmet need exists to find effective therapy in more severe ulcerative colitis (UC) patients, especially those who have failed multiple therapies. The efficacy and safety of upadacitinib, a selective Janus Kinase 1 inhibitor, has been assessed in an 8-week double-blind, placebo-controlled, dose-ranging, phase 2b induction study in adult patients with moderately-to-severely active UC (U-ACHIEVE). 1,2 METHODS: In U-ACHIEVE, adult patients with moderately-to-severely active UC as determined by the Adapted Mayo Score (5-9 points and centrally-read endoscopy subscore 2-3) were randomized to receive extended-release upadacitinib 7.5, 15, 30, 45 mg once daily (QD) or placebo for 8 weeks. In the current sub-analysis, the efficacy of upadacitinib in more severe and/or more refractory patient populations was assessed. Patients who at baseline had failed ≥2 prior biologic agents, had pancolitis, and/or an Adapted Mayo score >7, were included. Pairwise comparisons between upadacitinib doses and placebo for the primary endpoint, clinical remission per Adapted Mayo Score at Week 8 (defined as stool frequency subscore ≤1, rectal bleeding subscore = 0, and endoscopic subscore ≤1) and secondary endpoints were conducted using the Fisher's Exact test and no multiplicity adjustments were applied. Non-responder imputation was utilized for missing values. RESULTS: At baseline, 142 (56.8% of the total study population) patients had failed ≥2 prior biologics, 135 (54.0%) patients had pancolitis, and 90 (36.0%) patients had an Adapted Mayo score >7. The proportions of patients achieving endoscopic improvement, clinical response per Adapted Mayo score, and clinical response per Partial Mayo score were significantly higher (nominal P -value < 0.05) with upadacitinib doses ≥30 mg QD versus the placebo group in patients who failed ≥2 biologics or had pancolitis at baseline (Table 1). Trends of higher proportions of patients achieving clinical remission per Adapted Mayo score, endoscopic improvement, clinical response per Adapted Mayo score, and clinical response per Partial Mayo score were observed with all upadacitinib groups versus placebo in all the sub-analyses. CONCLUSION: In this dose-ranging induction study, upadacitinib demonstrated greater efficacy compared to placebo with dose response in the more severe and refractory population; significantly greater efficacy was demonstrated with upadacitinib at doses ≥30 mg QD for most of the endpoints evaluated.

Abstract Background & Aims Crohn’s disease (CD) is a lifelong illness with substantial morbidity, although new therapies and treatment paradigms have been developed. We provide guidance for treatment of ambulatory patients with mild to severe active luminal CD. Methods We performed a systematic review to identify published studies of the management of CD. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an iterative online platform and then finalized and voted on by a group of specialists. Results The consensus includes 41 statements focused on 6 main drug classes: antibiotics, 5-aminosalicylate, corticosteroids, immunosuppressants, biologic therapies, and other therapies. The group suggested against the use of antibiotics or 5-aminosalicylate as induction or maintenance therapies. Corticosteroid therapies (including budesonide) can be used as induction, but not maintenance therapies. Among immunosuppressants, thiopurines should not be used for induction, but can be used for maintenance therapy for selected low-risk patients. Parenteral methotrexate was proposed for induction and maintenance therapy in patients with corticosteroid-dependent CD. Biologic agents, including tumor necrosis factor antagonists, vedolizumab, and ustekinumab, were recommended for patients failed by conventional induction therapies and as maintenance therapy. The consensus group was unable to clearly define the role of concomitant immunosuppressant therapies in initiation of treatment with a biologic agent. Conclusions Optimal management of CD requires careful patient assessment, acknowledgement of patient preferences, evidence-based use of existing therapies, and thorough assessment to define treatment success.

Abstract Background PYRAMID was an international multicenter, noninterventional, postmarketing registry assessing long-term safety and effectiveness of adalimumab (Humira), as used in routine clinical practice. Methods Adult patients with moderately to severely active Crohn’s disease with or without prior adalimumab experience were enrolled in the registry and followed for up to 6 years. Effectiveness measurements included the Physician’s Global Assessment (PGA, a composite of Harvey Bradshaw Index [HBI] and rectal bleeding score), clinical remission (HBI < 5), Short Inflammatory Bowel Disease Questionnaire (SIBDQ), and Work Productivity and Activity Impairment (WPAI) questionnaire. Data were reported for adalimumab-naïve patients and analyzed by baseline immunomodulator use and disease duration. Results This study evaluated 2057 adalimumab-naïve patients. Mean PGA improved from 7.5 (baseline) to 3.9 (year 1) and 3.3 (year 6). The proportion of patients in HBI remission increased from 29% (573 of 1969; baseline) to 68% (900 of 1331; year 1) and 75% (625 of 831; year 6). Patients stratified by baseline immunomodulator use had similar HBI remission rates; patients with disease duration <2 years achieved numerically higher HBI remission rates than patients with longer disease duration. Patient-reported SIBDQ and WPAI scores improved at year 1; all WPAI subscore improvements were clinically meaningful (≥7% point change) at year 1 and maintained through year 6. Serious infections were reported in 11.1% of patients; incidence rates of malignancies, lymphoma, and demyelinating disorders were low. Conclusion Adalimumab therapy, as used in routine clinical practice, improved physician-reported and patient-reported disease outcomes and remission rates for up to 6 years. No new safety signals were observed.

Background: Vedolizumab (VDZ) is a gut-specific α4-β7 integrin antagonist that has demonstrated efficacy in Crohn’s disease (CD) and ulcerative colitis (UC). The safety of VDZ in the perioperative period remains unclear. The aim of this study was to evaluate postoperative complications and perioperative safety in VDZ-treated patients undergoing nonintestinal operations. Methods: A case-matched study was performed at two inflammatory bowel disease (IBD) referral centers. Adult patients with CD and UC who underwent a nonintestinal surgical procedure during treatment with VDZ were included. Patients who had their last VDZ infusion up to 12 weeks before the procedure were considered exposed and were matched in a 1:1 ratio to patients without VDZ therapy, according to type of surgical procedure, age, and sex. The primary outcome was overall risk of early postoperative infectious complications (up to 30 days after surgery), readmissions, reoperations, surgical site infections, and other infections. The VDZ and control groups were subsequently compared using the Pearson χ2 test and Wilcoxon rank sum. Results: We identified 34 patients treated with VDZ who underwent 36 nonintestinal surgical procedures. These patients were matched with 36 control procedures. Postoperative complications were not different between the VDZ-treated and control cohorts for all outcomes analyzed: infectious complications occurred in 14% versus 8% ( p = 0.45), superficial surgical site infections 6% versus 0% ( p = 0.15), reoperations 6% versus 3% ( p = 0.56) and readmissions 11% versus 6% ( p = 0.37). Conclusions: VDZ-treated patients with IBD undergoing nonintestinal procedures did not have an increased risk of overall postoperative infections or other complications compared with matched controls.
