Abstract
INTRODUCTION Biologic therapy is an effective treatment for inflammatory bowel disease [IBD]. However due to cost and safety concerns, dose de-escalation strategies after achieving remission have been suggested. AIM To critically review available data on dose de-escalation of biologics [or other advanced therapies] in IBD. We will focus on studies evaluating de-escalation to standard dosing in patients initially optimised, and also on studies assessing de-escalation from standard dosing. METHODS A systematic bibliographic search was performed. RESULTS The mean frequency of de-escalation after previous dose intensification [12 studies, 1,474 patients] was 34%. The corresponding frequency of de-escalation from standard dosing [five studies, 3,842 patients] was 4.2%. The relapse rate of IBD following anti-tumour necrosis factor [TNF] de-escalation to standard dosing in patients initially dose-escalated [10 studies, 301 patients] was 30%. The corresponding relapse rate following anti-TNF de-escalation from standard dosing [nine studies, 494 patients] was 38%. The risk of relapse was lower for patients in clinical, biologic, and endoscopic/radiological remission at the time of de-escalation. A role of anti-TNF therapeutic drug monitoring in the decision to dose de-escalate has been demonstrated. In patients relapsing after de-escalation, re-escalation is generally effective. De-escalation is not consistently associated with a better safety profile. The cost-effectiveness of the de-escalation strategy remains uncertain. Finally, there is not enough evidence to recommend dose de-escalation of biologics different from anti-TNFs or small molecules. CONCLUSIONS Any consideration for de-escalation of biologic therapy in IBD must be tailored, taking into account the risks and consequences of a flare and patients' preferences.

Abstract
PURPOSE Many patients treated for ulcerative colitis (UC) do not achieve clinical remission. This real-world study assessed clinical remission and inadequate response rates among patients with UC in Germany treated with advanced therapies. METHODS This retrospective chart review included patients with UC newly initiating advanced (index) therapy (anti-TNFα agents, vedolizumab, tofacitinib) from January 2017-September 2019 (index date). Included patients had data for ≥ 12 months before (baseline period) and after the index date (follow-up period). Remission was defined as a partial Mayo score ≤ 1. Indicators of inadequate response were: index therapy discontinuation; therapy adjustments (index therapy dose escalation; augmentation with non-advanced therapies; corticosteroid [CS] use during maintenance therapy); CS dependency (use for ≥ 12 weeks); and UC-related hospitalisation, surgery or emergency department visit. Time to first remission and inadequate response were analyzed using Kaplan-Meier analyses. RESULTS Among 149 patients with UC (median age: 40 years), 96 (64.4%) were biologic-naïve and 42 (28.2%) received CS at the index date. Within 12 months, 52 patients (47.2%) were in remission; of these, 13 patients (25.0%) received ≥ 1 therapy adjustment. At 12 months, 55 patients (37.6%) had ≥ 1 indicator of an inadequate response. Median time to remission was longer among biologic-experienced vs biologic-naïve patients (24 vs 7 months; p = 0.012). CONCLUSION Over half of the patients were not in clinical remission after 12 months and more than one-third experienced inadequate response. One-quarter of patients in remission required therapy adjustments. Patients with UC require therapies that are more effective than those currently available to achieve better treatment outcomes.

Abstract
INTRODUCTION Dose escalation is one of the treatment approaches studied and suggested in advanced therapies for Crohn's disease (CD) and ulcerative colitis (UC). This study aimed to identify and characterize the dosing escalation patterns of advanced therapies in CD and UC. METHODS Two systematic literature reviews (SLRs) were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE®, Embase®, and Cochrane Library were searched for articles published between January 2011 and October 2021 and limited to non-interventional studies in English language. Congress and bibliographic searches were also conducted. Articles were screened by two independent researchers. Dose escalation patterns were described and summarized considering the regional regulatory label recommendation (in North America [NA] or outside of North America [ONA]). RESULTS Among 3190 CD and 2116 UC articles identified in the Ovid searches, 100 CD and 54 UC studies were included in the SLR, with more studies conducted ONA. Most studies reported an initial maintenance dose pattern aligned with the lower starting dose per local regulatory label; however, several ONA studies (n = 13 out of 14) reported ustekinumab every 8 weeks as starting maintenance pattern in CD. In ONA studies, the median within-guideline escalation rates in CD and UC were 43% in ustekinumab (CD only), 33% and 32% for vedolizumab; 29% and 39% for adalimumab; and 14% and 10% for infliximab. Evidence regarding dose escalation patterns for tofacitinib, certolizumab pegol, and golimumab was limited. Some dose escalation patterns outside of label recommendations were observed including ustekinumab every 8 weeks to every 4 weeks and vedolizumab every 8 weeks to every 6 weeks. CONCLUSION Dose escalation strategies are widely documented in the literature. The reported dose escalation patterns and escalation rates vary by region and by CD and UC. Most escalation patterns reported were aligned with regulatory recommendations while some reported more diverse or aggressive dose escalation. PROSPERO REGISTRATION CRD42021289251.

A Systematic Review of the Economic and Health-Related Quality of Life Impact of Advanced Therapies Used to Treat Moderate-to-Severe Ulcerative Colitis. Adv Ther 2023; 40:2116-2146. [PMID: 37000363 PMCID: PMC10130125 DOI: 10.1007/s12325-023-02488-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 03/06/2023] [Indexed: 04/01/2023]
Abstract
INTRODUCTION The clinical benefits of advanced therapies (i.e., biologics and small-molecule drugs) in the treatment of moderate-to-severe ulcerative colitis (UC) have been demonstrated; however, there is less clarity regarding the economic and health-related quality of life (HRQoL) impact of these treatments. We conducted a systematic literature review to synthesize data on cost, healthcare resource utilization (HCRU), and HRQoL for patients who received approved advanced therapies for moderate-to-severe UC in the United States and Europe. METHODS Databases including MEDLINE, Embase, the Database of Abstracts of Reviews of Effects (DARE), the National Health Service Economic Evaluation Database (NHS EED), and EconLit were searched systematically to identify observational studies published between January 1, 2010 and October 14, 2021 that assessed the impact of advanced therapies on cost, HCRU, and/or HRQoL in adults with moderate-to-severe UC. Supplementary gray literature searches of conference proceedings from the past 4 years (January 2018 to October 2021) were also performed. RESULTS 47 publications of 40 unique cost/HCRU studies and 13 publications of nine unique HRQoL studies were included. Findings demonstrated that biologics have a positive impact on indirect costs (i.e., productivity, presenteeism, and absenteeism) and HRQoL. High costs of biologics were not always fully offset by reductions in cost and HCRU associated with disease management. For many patients, treatment switching and dose escalations were required, thus increasing drug costs, particularly when switching across treatment classes. CONCLUSION These findings highlight a high unmet need for therapies for moderate-to-severe UC that can reduce the healthcare burden and impact on society. Further research is warranted, as the reported evidence was limited by the small sample sizes of some treatment groups within a study.

Abstract
Background Currently approved biologic therapies for moderate-to-severe ulcerative colitis have well-established efficacy. However, many patients fail to respond or lose response, leading to dose escalation or treatment switching. Objective We sought to identify real-world evidence on dose escalation and treatment switching and associated clinical and economic outcomes among adults with ulcerative colitis treated with infliximab, adalimumab, golimumab, vedolizumab, ustekinumab, or tofacitinib. Methods We conducted a systematic search of Embase, MEDLINE (up to 26 August 2020), and conference proceedings (2017-2020) for studies in adults with ulcerative colitis to assess clinical response and remission, colectomy, adverse events, and economic outcomes related to dose escalation and treatment switching. Results In 56 studies, dose escalation and treatment switching involving infliximab and/or adalimumab were most frequently investigated. Rates of clinical response after dose escalation were 20-95% (1.8-36 months), clinical remission rates were 10-94% (1.8-36 months), colectomy rates were 0-33% (12-38 months), and adverse event rates were 0-18%. Treatment switching rates in 21 studies were 4-70% over 3-62 months, with switch due to loss of response rates of 4-35% over 12-62 months (7 studies). Up to 35% of patients underwent colectomy 12-120 weeks after switching, and 13-38% experienced adverse events. Data relating to economic outcomes were limited to tumor necrosis factor inhibitors, but demonstrated increased direct costs associated with both dose escalation and treatment switching. Conclusion Dose escalation and treatment switching are common with existing therapies. However, clinical response and remission rates vary, and a proportion of patients fail to achieve optimal clinical and economic outcomes. This highlights the need for more efficacious and durable treatments for patients with moderate-to-severe ulcerative colitis.

Abstract
Objective The aim of the study was to improve understanding of adherence and persistence to biologics, and their association with health-care resource utilization (HCRU), in Japanese patients with moderate to severe ulcerative colitis (UC). Methods Data were from Medical Data Vision, a secondary care administrative database. A retrospective, longitudinal cohort analysis was conducted of data from UC patients initiating biologic therapy between August 2013 and July 2016. Data collected for 2 years prior (baseline) and 2 years after (follow-up) the index date were evaluated. Patients completing biologic induction were identified, and adherence/persistence to biologic therapy calculated. HCRU, steroid, and immunosuppressant use during baseline and follow-up were assessed. Biologic switching during the follow-up was evaluated. Descriptive statistics (e.g., means and proportions) were obtained and inferential analyses (from Student's t tests, Fisher's exact tests, χ2 tests, the Cox proportional hazard model, and negative binomial regression) were performed. Results The analysis included 649 patients (adalimumab: 265; infliximab: 384). Biologic induction was completed by 80% of patients. Adherence to adalimumab was higher than that to infliximab (p < 0.001). Persistence at 6, 12, 18, and 24 months was higher with infliximab than with adalimumab (p < 0.05). Overall, gastroenterology outpatient visits increased, and hospitalization frequency and duration decreased, from baseline to follow-up. UC-related hospitalizations were fewer and shorter, and endoscopies fewer, in persistent than in nonpersistent patients, although persistent patients made more outpatient visits than nonpersistent patients. Hospitalization duration was lower in persistent than nonpersistent patients. Approximately 50% of patients received an immunosuppressant during biologic therapy; 5% received a concomitant steroid during biologic therapy. Overall, 17% and 3% of patients, respectively, received 2nd line and 3rd line biologics. Conclusions Poor biologic persistence was associated with increased non-medication-associated HCRU. Effective treatments with high persistence levels and limited associated HCRU are needed in UC.

Abstract
:
Ulcerative colitis (UC); an inflammatory bowel disease primarily affects the mucosa of
the colon. Depending on its mode of appearance, it can affect either the entire colon or even the distal
rectum. UC can manifest in both genders and every generation, but most generally appear in people
between the ages of 15 and 30. The extracellular matrix protein-1 (ECM1) gene is an important
candidate, mutations leading to tissue damage in patients with ECM1 single-nucleotide polymorphisms
are likely to intensify tissue damage caused by Metalloproteinase9 resulting in UC. In this
analysis, approval for the synthesis of Chemical Compound was obtained from the scientific committee
of the Department of Traditional Chinese Medicine, Qilu Hospital, China. Several derivatives
used as UC therapy were selected to build the pharmacophore model, using a ligand-based pharmacophore
modeling approach and virtual screenings were done for the identification of suitable drug
compounds. The selected compound was then synthesized in-vitro and validated using the molecular
docking technique. The synthesized compound fulfills all the characteristics of the non-toxic existence
of other drug-likeness laws. The specific interactive amino acids found in the docked complex
are arginine (ARG):47, lysine (LYS):54, phenylalanine (PHE):141, aspargine (ASN):51, serine
(SER):219, histadine (HIS):144, PHE:214, valine(VAL):220, tyrosine(TYR):145, and TYR:284. The
interaction of the synthesized compound with mutated TYR:284 of ECM1 confirmed the viability
and safety of a drug molecule as a medication in Ulcerative Colitis care. In the future, its validity can
be explored in the laboratory and this synthesized compound can be used as a medication target in
clinical studies against TYR:284 mutation in the ECM1 gene.

Abstract
BACKGROUND Inflammatory bowel diseases (IBD) are chronic, relapsing-remitting inflammatory conditions with a substantial negative impact on health-related quality of life and work productivity. Treatment of IBD has been revolutionized by the advent of biologic therapies, initially with anti-TNF agents and more recently with multiple alternatives targets, and yet more under development. OBJECTIVES Approximatively one third of patients do not respond to biologic therapy and more importantly a significant proportion experiences partial response or loss of response during treatment. The latter are common clinical situations and paradoxically are not addressed in the commercial drug labels and available guidelines. There is therefore a clinical need for physicians to understand when and how eventually to optimize the biologic therapy. DESIGN This consensus using a Delphi methodology was promoted and supported by the Emirates Society of Gastroenterology and Hepatology to close this gap. DATA SOURCES AND METHODS Following an extensive systematic review of over 60,000 studies, 81 studies with dose escalation and five addressing drug monitoring were selected and in addition five systematic reviews and three guidelines. RESULTS AND CONCLUSION after three rounds of voting 18 statements were selected with agreement ranging from of 80% to 100.

Abstract
Loss of response to antitumor necrosis factor (anti-TNF) therapies in inflammatory bowel disease occurs in a high proportion of patients. Our aim was to evaluate the loss of response to anti-TNF therapy, considered as the need for dose intensification (DI), DI effectiveness and the possible variables influencing its requirements. Bibliographical searches were performed. SELECTION prospective and retrospective studies assessing DI in Crohn's disease and ulcerative colitis patients treated for at least 12 weeks with an anti-TNF drug. EXCLUSION CRITERIA studies using anti-TNF as a prophylaxis for the postoperative recurrence in Crohn's disease or those where DI was based on therapeutic drug monitoring. DATA SYNTHESIS effectiveness by intention-to-treat (random effects model). Data were stratified by medical condition (ulcerative colitis vs. Crohn's disease), anti-TNF drug and follow-up. RESULTS One hundred and seventy-three studies (33,241 patients) were included. Overall rate of the DI requirement after 12 months was 28% (95% CI 24-32, I2 = 96%, 41 studies) in naïve patients and 39% (95% CI 31-47, I2 = 86%, 18 studies) in non-naïve patients. The DI requirement rate was higher both in those with prior anti-TNF exposure (p = 0.01) and with ulcerative colitis (p = 0.02). The DI requirement rate in naïve patients after 36 months was 35% (95% CI 28-43%; I2 = 98%; 18 studies). The overall short-term response and remission rates of empirical DI in naïve patients were 63% (95% CI 48-78%; I2 = 99%; 32 studies) and 48% (95% CI: 39-58%; I2 = 92%; 25 studies), respectively. The loss of response to anti-TNF agents-and, consequently, DI-occurred frequently in inflammatory bowel disease (approximately in one-fourth at one year and in one-third at 3 years). Empirical DI was a relatively effective therapeutic option.

Abstract
The incidence of ulcerative colitis (UC) is high. Despite the availability of various therapeutic agents for the treatment of UC, the routine treatment has limitations and serious side effects. Therefore, a new drug that safely and effectively treats UC is urgently needed. Polysaccharides from natural resources have recently become a hot topic of study for their therapeutic effects on UC. These effects are associated with the regulation of inflammatory cytokines, intestinal flora, and immune system and protection of the intestinal mucosa. This review focuses on the recent advances of polysaccharides from natural resources in the treatment of UC. The mechanisms and practicability of polysaccharides, including pectin, guar gum, rhamnogalacturonan, chitosan, fructan, psyllium, glycosaminoglycan, algal polysaccharides, polysaccharides from fungi and traditional Chinese medicine, and polysaccharide derivatives, are discussed in detail. The good efficacy and safety of polysaccharides make them promising drugs for treating UC.
