Medication adherence to inflammatory bowel disease medications in Aotearoa New Zealand and correlation with health outcomes: A nationwide database analysis. Br J Clin Pharmacol 2024; 90:1911-1920. [PMID: 38689379 DOI: 10.1111/bcp.16069] [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: 08/09/2023] [Revised: 01/30/2024] [Accepted: 03/18/2024] [Indexed: 05/02/2024] Open
Abstract
AIMS Inflammatory bowel disease (IBD) management entails long-term medication therapy. Worse disease outcomes and reduced quality of life might arise from poor medication adherence (MA). This study is the first to investigate patients with IBD's adherence across Aotearoa New Zealand and its relationship with disease outcomes. METHODS Dispensing claims data (Pharmaceutical Collection) were used to calculate (3- and 5-year) adherence, using daily polypharmacy possession ratio. Using hospitalization data (National Minimum Dataset), the relationship between adherence and the numbers of hospitalizations and corticosteroid dispensings was investigated. RESULTS In total, 4654 patients (53% female; 55% Crohn's disease [CD], 45% ulcerative colitis [UC]; median age-at-first-dispensing, 43 years) and 3148 patients (54% female; 55% CD, 44% UC; median age-at-first-dispensing, 44 years) were in the 3- and 5-year cohorts, respectively. The 3- and 5-year cohorts had mean 4.6 and 4.2 IBD-related hospitalizations and 6.9 and 9.2 corticosteroid dispensings, respectively. Average adherence estimates were 77.4% (95% confidence interval: 76.9-78.0%) and 74.9% (95% confidence interval: 74.1-75.6%; 3 and 5 years), while 54% and 51% of patients, respectively, had good adherence (MA ≥ 80%). There was no correlation between adherence and the numbers of hospitalizations (Pearson's R = -.0007; P = .65 and R = -.04; P = .02 [3 and 5 years]) and corticosteroid dispensings (R = .08; P = <.0001 and R = .08; P = <.0001, respectively). CONCLUSION MA of Aotearoa New Zealand patients with IBD is moderately high but just over half of patients meet the adherent threshold. There was no correlation between adherence and hospitalizations or corticosteroid dispensings; hence, research into longitudinal adherence patterns and associated factors is needed.

Inflammatory bowel disease (IBD) patients with impaired quality of life on biologic therapy benefit from the support of an IBD nurse specialist: Results of a randomised controlled trial in Germany (IBD BIO-ASSIST study). Aliment Pharmacol Ther 2024; 59:1082-1095. [PMID: 38429885 DOI: 10.1111/apt.17926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 11/16/2024] [Accepted: 02/15/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND IBDBIO-ASSIST was a randomised controlled trial assessing the efficacy of care provided by IBD nurse specialists in Germany in improving health-related quality of life (QoL) in IBD patients on biologic therapy. AIM To evaluate patient-related outcomes and economic consequences associated with integrating IBD nurses into usual care. METHODS We randomly assigned 1086 patients with IBD on biologic therapy to a control group (CG) receiving usual care or an intervention group (IG) receiving additional care from an IBD nurse specialist. The primary outcome was disease-specific QoL (sIBDQ) assessed at 6, 12 and 18 months. RESULTS At baseline, patients in both groups were highly satisfied with their treatment situation and had relatively high sIBDQ values (range: 1-7; CG: 5.12; IG: 4.92). In the intention-to-treat (ITT) analysis of the overall sample, there was no significant difference in sIBDQ between groups at the assessment time points. However, a per-protocol analysis of patients with impaired QoL at baseline (EQ-VAS < 75 [median]), showed improvement in sIBDQ over 6 months that became significant at month 12 and remained significant through month 18 (baseline: IG 4.24; CG 4.31; 18 months: IG 5.02; CG 4.76; p = 0.017). CONCLUSION High baseline satisfaction of IBD patients with treatment and the relatively high baseline sIBDQ values may have contributed to the lack of significant difference in sIBDQ scores for the overall sample. However, patients with impaired QoL derived significant benefit from additional care provided by an IBD nurse specialist, leading to meaningful improvements in sIBDQ over the long term.

Abstract
Inflammatory bowel disease (IBD) management is typified by a long-term medication regimen which can comprise multiple medications prescribed in different combinations, doses, frequencies, and with various administration routes. This complexity can make medication adherence (MA) - patients taking their medications per the prescription - for patients with IBD a challenge. The research corpus contains diverse interventions aimed at improving MA in patients with IBD. Therefore, to condense the evidenced strategies for ease of reference, this narrative evidence-based review broadly outlines the patient-level interventions reported. The interventions are grouped as educational, behavioural, cognitive-behavioural, and multicomponent. They, however, present mixed results as to their efficacy at improving MA, with those employing combined approaches being the most promising. This reflects the reality that MA is impacted by multiple factors encompassing those pertaining to the patient, disease, therapy, patients' socioeconomic status, and health system. Hence, the most ideal interventions would likely be multifaceted patient-level interventions alongside policy/system-level strategies, to maximise the potential for successfully improving patients' MA. These findings might have been impacted by the heterogeneity of the studies in terms of the method of MA assessment, duration of interventions, and more besides.

Abstract
Purpose To describe real-world persistence in bio-naïve and bio-experienced adults with ulcerative colitis (UC) treated with ustekinumab, a recently approved anti-interleukin 12/23 antibody, or adalimumab, an anti-TNF biologic. Methods This is a descriptive, retrospective cohort study. Patients initiating ustekinumab or adalimumab (index date, between 10/21/2019 and 08/13/2021) were selected from the Komodo Health comprehensive dataset and stratified into bio-naïve and bio-experienced subgroups based on biologic use 12 months pre-index date. Endpoints evaluated at 12-months after maintenance phase start using Kaplan-Meier analysis included 1) persistence; 2) persistence while being corticosteroid-free (<14 consecutive days of corticosteroid supply after day 90 post-index); and, 3) persistence while on monotherapy (no immunomodulators/non-index biologics/advanced therapies). Results Ustekinumab cohort included 778 patients (236 bio-naïve, 542 bio-experienced) and adalimumab cohort included 1693 patients (1517 bio-naive, 176 bio-experienced). At 12 months after maintenance phase start, 75.5% and 50.5% of bio-naïve patients persisted on ustekinumab and adalimumab and 72.3% and 56.9% of bio-experienced patients persisted on ustekinumab and adalimumab, respectively. Further, 55.1% and 38.2% of bio-naïve patients were persistent and corticosteroid-free with ustekinumab and adalimumab; 43.7% and 33.4% of bio-experienced patients were persistent and corticosteroid-free with ustekinumab and adalimumab, respectively. Moreover, 68.1% and 44.5% of bio-naïve patients were persistent and on monotherapy with ustekinumab and adalimumab; 61.6% and 47.9% of bio-experienced patients were persistent and on monotherapy with ustekinumab and adalimumab, respectively. Conclusion At 12 months after maintenance phase start, patients with UC treated with ustekinumab had numerically higher persistence, including persistence while corticosteroid-free and persistence while on monotherapy, than patients treated with adalimumab.

The economic impact of suboptimal treatment and treatment switch among patients with Crohn's disease treated with a first-line biologic - A US retrospective claims database study. J Med Econ 2024; 27:931-940. [PMID: 38965985 DOI: 10.1080/13696998.2024.2374645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Accepted: 06/27/2024] [Indexed: 07/06/2024]
Abstract
AIMS Suboptimal treatment indicators, including treatment switch, are common among patients with Crohn's disease (CD), but little is known about their associated healthcare resource utilization (HRU) and costs. This study assessed the impact of suboptimal treatment indicators on HRU and costs among adults with CD newly treated with a first-line biologic. METHODS Adult patients with CD were identified in the IBM MarketScan Commercial Subset (10/01/2015-03/31/2020). The index date was defined as initiation of the first-line biologic, and the study period was defined as the 12 months following the index date. Patients were classified into Suboptimal Treatment and Optimal Treatment cohorts based on observed indicators of suboptimal treatment during the study period. Patients in the Suboptimal Treatment Cohort with a treatment switch were classified into the Treatment Switch Cohort and compared to patients with no treatment switch. All-cause HRU and costs were measured during the study period and assessed for patients with suboptimal vs optimal treatment and patients with vs without a treatment switch. RESULTS The study included 4,006 patients (Suboptimal Treatment: 2,091, Optimal Treatment: 1,915). Treatment switch was a common indicator of suboptimal treatment (Treatment Switch: 640, No Treatment Switch: 3,366). HRU and costs were significantly higher among patients with suboptimal treatment than those with optimal treatment (annual costs: $92,043 vs $73,764; p < 0.01), and among those with a treatment switch than those with no treatment switch (annual costs: $95,689 vs $81,027; p < 0.01). Increases in the number of suboptimal treatment indicators were associated with increased costs. LIMITATIONS Claims data were used to identify suboptimal treatment indicators based on observed treatment patterns; reasons for treatment decisions could not be assessed. CONCLUSION This study demonstrates that patients with suboptimal treatment indicators, including treatment switch, incur substantially higher HRU and costs compared to patients receiving optimal treatment and those that do not switch treatments.

Abstract
Adsorptive cytapheresis proves effective in a proportion of patients affected by ulcerative colitis. Relatively high cost and the need for apheresis facilities, prevented the widespread use of this therapeutic approach. More so following the introduction of anti-TNFα biosimilars which proved both effective and inexpensive. Anti-TNFα agents, however, are burdened by high rate of primary and secondary non-response and prompt switching to new, high-cost biologics, and small molecules. The present review analyzes advantages and disadvantages of adsorptive cytapheresis in the present clinical scenario and suggests its repositioning in the therapeutic workup of selected subgroups of ulcerative colitis patients. The extremely favorable safety profile makes adsorptive cytapheresis a viable therapeutic option in elderly and high-risk UC patients, as well as potential second-line treatment in corticosteroid-dependent patients and poor responders to first-line biologics.

Abstract
Background A careful, often life-long, medication regimen is central to therapy for Inflammatory Bowel Disease (IBD) - a chronic gut disorder. Hence, medication adherence (MA) - patients taking medications in line with prescription - is important. Previous research indicates that a third of patients with IBD in southern New Zealand have poor medication adherence (MA). Objective This study investigated these patients' experiences to determine factors that influence their MA, for the first time. Methods Two focus group discussions (FGDs) were held with IBD patients in Otago, New Zealand. Reflexive thematic analysis from a 'direct realist' viewpoint was used to analyse the data. Results Data were analysed in three segments: perceptions, experiences and support. Participants perceived MA as a "duty" that was very important to their wellbeing. The participants' MA was centred around a routine requiring proactivity to maintain. MA was negatively impacted by side effects and regimen factors including (high) pill numbers/dose frequency, and getting refills was framed as challenging; whilst healthcare professionals were presented as major MA facilitators. Lastly, the support structures identified included family, friends and colleagues as well as targeted health system factors e.g. medication subsidies. Conclusions Factors spanning those related to the patients, their socioeconomic status, the disease, IBD therapy and the health system were presented as influencing IBD patients' MA in southern NZ. Thus, multifaceted interventions are needed across the health system to overcome the inhibiting and promote the facilitating elements.

Abstract
OBJECTIVE Although dosing regimens of targeted therapies (TT) for ulcerative colitis (UC) and Crohn's disease (CD) are guided by market authorizations and clinical guidelines, little is known about clinical guideline adherence or outcomes in patients receiving escalated doses of TT due to lack of response. This real-world study explored the prevalence of dose escalation and compared outcomes between patients receiving standard and escalated TT doses. METHODS Data were from the 2020-2021 Adelphi Disease Specific Programme for inflammatory bowel disease, a cross-sectional survey of gastroenterologists and their UC and CD patients across five European countries and the US. Physicians provided retrospective data collection of patient demographics, clinical characteristics, treatment history, and satisfaction; patients reported quality-of-life and work productivity. Patients were grouped by TT maintenance dose; standard and escalated dose groups were compared. Outcomes were adjusted for time on current TT and severity at current TT initiation using regression analyses. RESULTS Of 1,241 UC and 1,477 CD patients, 19.1% and 24.1%, respectively, received escalated TT doses. Despite escalation, a substantial proportion of patients had not achieved remission, had moderate or severe disease activity, or were flaring. Most physicians were not fully satisfied with treatment in the escalated dose group and were more likely to switch patients to another treatment regimen than patients on standard dose. CONCLUSION Dose escalation is not always an effective approach to resolve inadequate or loss of response in UC and CD, highlighting a need for more therapeutic options or alternative treatment strategies in patients unresponsive to TT.

Abstract
Background: There is limited real-world evidence on treatment patterns of patients with Crohn's disease (CD) initiating biologics with an extensive follow-up period. This study describes persistence and dose titration among CD patients with 3 years of follow-up. Methods: This retrospective observational study was conducted using the STATinMED RWD Insights all-payer medical and pharmacy data. Adult patients with at least 1 CD medical claim and at least 1 medical/pharmacy claim for a biologic (adalimumab [ADA], certolizumab pegol (CZP), infliximab [IFX] and its biosimilar products [IFX-BS], ustekinumab [UST], and vedolizumab [VDZ]) between September 2016 and October 2018 were identified. Commercially insured patients with continuous capture for at least 12 months before and at least 36 months after biologics initiation were selected. Confirmed CD patients were included in the final cohort. Baseline patient characteristics and treatment patterns over the 3-year follow-up period were evaluated. Results were summarized using means and SD or counts and percentages. Results: A total of 2309 confirmed patients with CD were identified (847 [36.7%] IFX, 534 [23.1%] ADA, 486 [21.1%] VDZ, 394 [17.1%] UST, 85 [3.7%] CZP, and 72 [3.1%] IFX-BS). CZP and IFX-BS were excluded due to small sample sizes. Approximately half of CD patients were between ages 35 and 54. Patients on UST had a higher Charlson Comorbidity Index score. Common comorbidities (>10%) included anemia, anxiety, depression, and hypertension. Persistence over 3 years' follow-up was highest for UST (61.4%) patients, followed by VDZ (58.0% ), ADA (52.1% , and IFX (48.1%). The discontinuation rate without switch or restart was highest for ADA (37.3%), followed by UST (30.7%), IFX (28.1%), and VDZ (25.3%). Over the 3 years of follow-up, the dose titration rate was highest for IFX (76.5%) and lowest for UST (50.8%). In particular, UST had the lowest dose escalation rate (35.5%) and highest dose-reduction rate (16.5%). Conclusions: Patients with CD on UST had the highest persistence and lowest dose escalation across different biologic users over the 3-year follow-up period, possibly suggesting a better clinical response of UST. Future studies with longer follow-up adjusting for confounders are needed to better understand treatment patterns among biologics users.

Abstract
OBJECTIVE To estimate long-term persistence among bio-naïve patients with CD initiated on ustekinumab or adalimumab. METHODS Adults with CD initiating ustekinumab or adalimumab (index date, between September 23, 2016 and August 1, 2019) were sampled from the IBM MarketScan Commercial Database. Patients without CD-indicated biologics (bio-naïve) and with no diagnoses for other autoimmune diseases 12 months pre-index date (baseline) were included. Cohorts were balanced on baseline characteristics with inverse probability of treatment weighting. Persistence was defined as the absence of therapy exposure gaps >120 days (ustekinumab) or >60 (adalimumab) between days of supply. Composite endpoints were persistence and being corticosteroid-free (no corticosteroids >14 days of supply after day 90 post-index) and persistence while on monotherapy (no immunomodulators/non-index biologics). Persistence was analyzed using Kaplan-Meier and Cox's models. RESULTS Ustekinumab and adalimumab cohorts included 671 and 2,975 patients. At 12 months post-index, ustekinumab patients were significantly more persistent (hazard ratio [HR] = 1.60; 95% confidence interval [CI] = 1.33-1.93), persistent while on monotherapy (HR = 1.43; 95% CI = 1.24-1.65), and trended toward being more persistent and corticosteroid-free (HR = 1.14; 95% CI = 0.99-1.30) vs adalimumab. At 24 months post-index, ustekinumab patients were significantly more persistent (HR = 1.66; 95% CI = 1.40-1.97), persistent while on monotherapy (HR = 1.44; 95% CI = 1.26-1.64), and persistent and corticosteroid-free (HR = 1.15; 95% CI = 1.01-1.31) vs adalimumab. CONCLUSIONS Bio-naïve patients with CD initiated on ustekinumab demonstrated significantly more persistence than patients initiated on adalimumab at 12 and 24 months of treatment. Long-term persistence is a measure of a drug's real-world performance and findings may aid clinical decision-making.

[PMID: 36520519 PMCID: PMC9801266 DOI: 10.2196/40382] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 10/26/2022] [Accepted: 10/28/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Inflammatory bowel diseases (IBDs) are chronic inflammatory conditions of the gastrointestinal tract. Although adherence to IBD therapies is associated with improved clinical outcomes, overall adherence is poor. Consequently, there is a critical need to develop interventions that monitor adherence in real time and identify reasons for nonadherence to support clinical teams in initiating effective interventions. Recently, electronic- and web-based platforms have been developed to monitor adherence and guide interventions. A novel remote therapy monitoring (RTM) technology, the Tappt digital health system, has been developed to monitor real-time medication adherence patterns through smart label technologies, capture patient-reported outcomes and barriers to care, and process patient data through algorithms that trigger personalized digital and human touch points between clinical visits. Such a digital health solution enables care teams to proactively identify and mitigate nonadherence and worsening clinical outcomes. OBJECTIVE We propose a 12-month multicenter randomized controlled trial to assess the effectiveness of the Tappt digital health system on adherence, clinical outcomes, and health care use among patients diagnosed with IBD starting a new oral or subcutaneous therapy. METHODS The digital health system intervention will provide automatic measurement of medication adherence via smart labels for pill bottles or injectors as well as a monitoring platform for providers. The system will prompt patients to complete a two-item assessment of symptoms monthly using the PRO-2 scales for UC and Crohn disease, from which increased symptoms will be alerted to providers. Participants will be randomized 2:1 to the intervention group or the control group, which will receive standard of care. All participants are required to complete questionnaires at baseline as well as at 12, 26, and 52 weeks. Assuming an adherence rate of 0.65 and 0.9 among control and intervention participants, respectively, we will need to enroll 123 participants: 82 (66.7%) in the intervention group and 41 (33.3%) controls. We will compare adherence as measured by the medication possession ratio, defined as the number of days of supply of medication obtained during the observation period out of the total number of days in the observation period, in participants using the RTM versus those receiving standard of care. We will also compare clinical outcomes and health care use in participants using the RTM versus those receiving standard of care. RESULTS We anticipate starting recruitment in December 2022. CONCLUSIONS Effective medication adherence monitoring and intervention programs need to be cost-efficient, pose little or no burden to the patient, record reliable data in real time, and provide actionable insights to the health care team. We anticipate the Tappt digital health system to improve the medication possession ratio, clinical outcomes, and health care use compared with standard of care.

Front Med (Lausanne) 2022; 9:897936. [PMID: 35783628 PMCID: PMC9241563 DOI: 10.3389/fmed.2022.897936] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 05/25/2022] [Indexed: 11/30/2022] Open
Abstract
Anti-tumor necrosis factor (anti-TNF) therapy has been successfully used as first-line biologic treatment for moderate-to-severe inflammatory bowel disease (IBD), in both “step-up” and “top-down” approaches, and has become a cornerstone of IBD management. However, in a proportion of patients the effectiveness of anti-TNF therapy is sub-optimal. Either patients do not achieve adequate initial response (primary non-response) or they lose response after initial success (loss of response). Therapeutic drug monitoring determines drug serum concentrations and the presence of anti-drug antibodies (ADAbs) and can help guide treatment optimization to improve patient outcomes. For patients with low drug concentrations who are ADAb-negative or display low levels of ADAbs, dose escalation is recommended. Should response remain unchanged following dose optimization the question whether to switch within class (anti-TNF) or out of class (different mechanism of action) arises. If ADAb levels are high and the patient has previously benefited from anti-TNF therapy, then switching within class is a viable option as ADAbs are molecule specific. Addition of an immunomodulator may lead to a decrease in ADAbs and a regaining of response in a proportion of patients. If a patient does not achieve a robust therapeutic response with an initial anti-TNF despite adequate drug levels, then switching out of class is appropriate. In conjunction with the guidance above, other factors including patient preference, age, comorbidities, disease phenotype, extra-intestinal manifestations, and treatment costs need to be factored into the treatment decision. In this review we discuss current evidence in this field and provide guidance on therapeutic decision-making in clinical situations.

Abstract
Despite the large number of biologics currently available for moderate-to-severe psoriasis, poor adherence and persistence to therapy represent the main issues for both the clinical and economic management of psoriasis. However, the data about adherence and persistence to biologics in psoriasis patients are conflicting. Our aim was to produce summary estimates of adherence and persistence to biologics in adult patients with psoriasis. We performed a systematic review and meta-analysis of observational studies, searching two databases (PubMed and Embase). Sixty-two records met the inclusion criteria, and a meta-analysis was conducted on fifty-five studies. Overall, the proportion of adherent and persistent patients to biological therapy was 0.61 (95% confidence interval: 0.48–0.73) and 0.63 (0.57–0.68), respectively. The highest proportions were found for ustekinumab, while the lowest ones were found for etanercept. The proportions of adherence and persistence to biological drugs in psoriasis patients are sub-optimal. Notably, both proportions largely differ between drugs, suggesting that a more rational use of biologics might ensure better management of psoriasis.

Abstract
The human race is consistently striving for achieving good health and eliminate disease-causing factors. For the last few decades, scientists have been endeavoring to invent and innovate technologies that can substitute the conventional dosage forms and enable targeted and prolonged drug release at a particular site. The novel multi-matrix technology is a type of matrix formulation where the formulation is embraced to have a matrix system with multiple number of matrices. The MMX technology embraces with a combination of outer hydrophilic layer and amphiphilic/lipophilic core layer, within which drug is encapsulated followed by enteric coating for extended/targeted release at the required site. In comparison to conventional oral drug delivery systems and other drug delivery systems, multi-matrix (MMX) technology formulations afford many advantages. Additionally, it attributes for targeting strategy aimed at the colon and offers modified prolonged drug release. Thus, it has emerged rapidly as a potential alternative option in targeted oral drug delivery. However, the development of this MMX technology formulations is a exigent task and also has its own set of limitations. Due to its promising advantages and colon targeting strategy over the other colon targeted drug delivery systems, premier global companies are exploiting its potential. This article review deep insights into the formulation procedures, drug delivery mechanism, advantages, limitations, safety and efficacy studies of various marketed drug formulations of MMX technology including regulatory perspectives and future perspectives.

Abstract
Biologics are recommended in Japan to treat moderate to severe Crohn’s Disease (CD). Although CD is associated with high direct costs in Japan, updated information after ustekinumab’s approval is unavailable. We aimed to evaluate the healthcare resource utilization (HRU) and associated direct costs from the payer’s perspective in Japan. Claims data (2010–2018) were retrospectively analyzed to identify patients with CD. HRU and associated costs were evaluated for 12 months before and after biologic initiation and followed-up till 36 months post-initiation. Outcomes were reported using descriptive statistics. Among the included patients (n = 3,496), 1,783 were on biologics and 1,713 were on non-biologics. Mean (SD) age was 36.4 (13.2) years and patients were predominantly male (76.1%). Patients aged 18–39 years were affected with CD the most (55.3%). Biologic initiation was associated with a reduction in inpatient stay, length of stay, outpatient visits, and associated costs; and an increase in pharmacy costs and total costs after 12 months. Extended follow-up showed a decreasing trend in HRU and costs till 24 months but an increase after 36 months. These findings demonstrated reduction in clinical burden and slight increase in economic burden with biologics. However, indirect costs also need to be evaluated.

Abstract
OBJECTIVES 1)To analyze evidence about poor adherence / non-adherence including their prevalences, associated factors, and interventions in ulcerative colitis (UC) patients; 2)To provide a framework to improve poor adherence / non-adherence. METHODS A qualitative approach was applied. A literature review was performed using Medline. Primary searches were performed with Mesh and free texts to identify articles that analyzed prevalence, causes, associated factors, and interventions designed to improve poor adherence/ non-adherence in UC patients. The studies' quality was evaluated using the Oxford scale. The results were presented and discussed in a nominal group meeting, comprising a multidisciplinary committee of six gastroenterologists, one psychologist, one nurse, and one patient. Several overarching principles and recommendations were generated. A consensus procedure was implemented via a Delphi process during which each committee member produced a score ranging from 0 = totally disagree to 10 = totally agree. Agreement was considered if at least 70% of the participants voted ≥7. RESULTS The literature review included 75 articles. Non-adherence rates ranged from 7%-72%. We found a great variability in the methods employed to assess adherence, associated factors, and interventions designed to improve adherence. Overall, eight overarching principles and six recommendations were generated, all of them achieving the pre-established agreement level, including, among others, the identification, classification, and management of non-adherence. CONCLUSIONS Poor adherence / non-adherence are common in UC patients, being a relevant clinical concern. Health professionals should address this issue and actively involve the patients in implementing effective and individualized interventions to improve adherence.

Abstract
INTRODUCTION Adalimumab and golimumab are subcutaneously administered anti-tumor necrosis factor α (TNFα) biologics used in the treatment of ulcerative colitis (UC). To date, no studies have directly compared treatment patterns and healthcare resource utilization (HRU) among patients with UC receiving these therapies in a real-world setting. The objective of this study was to compare these outcomes among patients with UC treated with either adalimumab or golimumab using a US claims database. METHODS Patients with UC treated with golimumab or adalimumab were identified using the US Optum Clinformatics® Data Mart database. Outcomes of interest included treatment patterns (discontinuations, dose optimizations, persistence, and concomitant medication use) and HRU (outpatient office visits, emergency room [ER] visits, and inpatient stays). Propensity score matching (PSM) was used to account for differences in confounding variables between groups. RESULTS Overall, 990 patients were identified (golimumab: n = 277; adalimumab: n = 713). After PSM, 246 patients were included in each group. There were no significant differences between the adalimumab and golimumab groups over the full follow-up period in terms of treatment discontinuations (53.7% vs. 51.2%; P = 0.5881), dose optimizations (35.4% vs. 39.4%; P = 0.3515), or persistence (338.2 vs. 361.2 days; P = 0.4194). During the year after initiating therapy, there were no significant differences in concomitant immunosuppressant (21.9% vs. 21.7%; P = 0.9686) or corticosteroid use (74.7% vs. 78.8%; P = 0.3573) or in HRU outcomes including outpatient office visits (93.3% vs. 94.0%; P = 0.7660), ER visits (15.2% vs. 10.9%; P = 0.2238), and inpatient stays (15.2% vs. 13.6%; P = 0.6680). CONCLUSIONS In this nationwide PSM cohort study of patients with UC receiving golimumab or adalimumab, no significant differences were observed between groups for treatment patterns or HRU outcomes. High rates of concomitant corticosteroid use, treatment discontinuations, and HRU while on therapy highlight key unmet needs in the treatment of UC.

Abstract
Introduction Real-world treatment persistence to ustekinumab for Crohn’s disease (CD) was studied using Australian Pharmaceutical Benefits Scheme (PBS) data. Demographic and treatment pattern characteristics were also investigated. Methods Our retrospective cohort analysis included PBS 10% sample data for ustekinumab from September 2017 to March 2020, and for other biologics from October 2007 to capture earlier line(s) of therapy. Included patients received ustekinumab for CD prescribed by a gastroenterologist. Treatment persistence overall and by prior biologic experience, mono- or combination therapy, sex and age were estimated using Kaplan–Meier methods. A Cox proportional hazards regression analysis was performed to assess the effect of age, sex and line of therapy on persistence. Results Data were available for 301 patients. Of these, 58.8% were female and 76.7% were aged 26–65 years. Median follow-up from first ustekinumab dispense was 16 months. Median persistence to ustekinumab had not been reached. Twelve-month persistence to ustekinumab was 82.6% (95% CI 78.1–87.5%). Patients receiving ustekinumab as their first biologic therapy had 12-month persistence of 88.0% (80.8–95.9%) compared to 80.6% (75.0–86.6%) for patients who had previously received other biologic therapies (p=0.059). The adjusted analysis showed a trend to longer persistence for patients receiving ustekinumab as their first biologic therapy compared to biologic experienced patients (HR 1.86 (95% CI 0.95–3.63), p=0.070). Males had higher persistence to ustekinumab than females (HR 0.36 (0.20–0.66), p<0.001). Receiving ustekinumab as a monotherapy or in combination with azathioprine, mercaptopurine, 5ASAs, methotrexate, or corticosteroids had no effect on persistence (p=0.22). Conclusion In an Australian real-world setting, persistence to ustekinumab was demonstrated to be over 80% at 12 months. Use as monotherapy or in combination with other therapy for CD did not affect persistence. Differences in treatment persistence by gender and previous biologic use warrant further investigation as further long-term data becomes available. ![]()

Abstract
Background Real-world evidence for how US Crohn’s disease (CD) patients use ustekinumab is limited. Objectives The aim of this study was to describe the persistence, maintenance dosing, and pre-post corticosteroid and opioid use for CD patients in the USA treated with ustekinumab and those treated with adalimumab as a commonly used descriptive reference product. Methods CD patients aged ≥ 18 years with ≥2 CD diagnoses between 1 October 2012 and 31 May 2018 and ≥ 1 new (i.e., no claim for at least 1 year) outpatient pharmacy claim for ustekinumab or adalimumab (first claim date = index date) on or after 26 September 2016 were selected from Symphony Health database. McNemar’s tests were used to derive the p-values for pre-post changes in corticosteroid and opioid use within each treatment cohort. Results A total of 1073 ustekinumab and 2904 adalimumab patients met analysis criteria. Using a 90-day rule for discontinuation, persistence at 1 year post-index was 69.8% for ustekinumab and 65.1% for adalimumab. The majority received doses within ±30% of the approved labeling (ustekinumab 81.1%; adalimumab 78.8%). Doses higher than US package insert (PI) recommended maintenance dose were 7.0% for ustekinumab and 13.6% for adalimumab for 30% above PI, respectively; and 4.0% versus 9.4% for 50% above PI, respectively. Rates of pre-index biologic use suggest that patients treated with ustekinumab may have greater CD severity based on a greater percentage being biologic-experienced (ustekinumab 51.5% and adalimumab 8.4%). From pre- to post-index, the relative proportion of ustekinumab patients with ≥ 1 pharmacy claim for corticosteroids decreased by 25.5% (p < 0.0001) and opioids decreased by 8.4% (p = 0.0030). Results for adalimumab (a commonly used descriptive reference product in CD) showed generally similar trends. Conclusions In this real-world study, persistence for ustekinumab remained high at 1 year. The majority of the patients in the ustekinumab cohort followed US PI recommended dosing. The percentage of patients with average dose above PI recommendations over 1 year were low for ustekinumab. Reductions in the proportion of patients with claims for corticosteroids or opioids were observed in patients using ustekinumab.

Abstract
Background Ulcerative colitis (UC) is one of the most challenging human diseases. Natural shikonin (SK) and its derivatives (with have higher accumulation) isolated from the root of Lithospermum erythrorhizon have numerous beneficial effects, such as wound healing and anti-inflammatory activities. Some researchers have reported that hydroxynaphthoquinone mixture (HM) and SK attenuate the acute UC induced by dextran sulfate sodium (DSS). However, no existing study has systemically investigated the effectiveness of SK and other hydroxynaphthoquinone natural derivative monomers on UC. Methods In this study, mice were treated with SK and its derivatives (25 mg/kg) and mesalazine (200 mg/kg) after DSS administration daily for one week. Disease progression was monitored daily by observing the changes in clinical signs and body weight. Results Intragastric administration natural single naphthoquinone attenuated the malignant symptoms induced by DSS. SK or its derivatives remarkably suppressed the serum levels of pro-inflammatory cytokines while increasing the inflammatory cytokine interleukin (IL)-10 . Additionally, both SK and alkanin restrained the activities of cyclooxygenase-2 (COX-2), myeloperoxidase (MPO) and inducible nitric oxide synthase (iNOS) in serum and colonic tissues. SK and its derivatives inhibited the activation of nucleotide binding oligomerization domain-like receptors (NLRP3) inflammasome and NF-κB signaling pathway, thereby relieving the DSS-induced disruption of epithelial tight junction (TJ) in colonic tissues. Conclusions Our findings shed more lights on the pharmacological efficacy of SK and its derivatives in UC against inflammation and mucosal barrier damage.

Abstract
WHAT IS KNOWN AND OBJECTIVE Every prescriber knows that patients often do not take their medicines as prescribed. Hippocrates, the wise man of Kos, knew over two millennia ago. Our objective is to comment on the types of studies aimed at understanding and optimizing drug usage and to draw attention to the need to seek approval before using or citing the Morisky adherence scale. COMMENT The study of prescribing and how patients use their medicines is important. As part of this effort, the results of investigations of how patients adhere to drug prescriptions can be informative. However, the results are meaningful only if the methods used for doing the measurements are valid and made explicit. We were surprised when a team of our authors were threatened with legal action for citing the Morisky Adherence Scale and explaining how some authors had obtained their adherence scores. Adherence studies are but one facet of the study of prescribing aimed at improving clinical outcomes. Other aspects include investigating the quality of prescribing, and how unnecessary medicines can be deprescribed to improve the quality of care and reduce the risk of adverse effects. WHAT IS NEW AND CONCLUSION The study of optimal prescribing is an important endeavour and adherence studies are but one aspect. We report that using and citing the Morisky Adherence scale in any detail is a risky business. Prior approval is required unless one is prepared to pay up, retrospectively. We require all authors to certify they have no conflicts of interest with respect to the scale.

Treatment persistence and colectomy-free outcomes in patients with ulcerative colitis receiving golimumab or adalimumab: a UK experience. BMJ Open Gastroenterol 2020; 7:bmjgast-2020-000476. [PMID: 33199269 PMCID: PMC7670853 DOI: 10.1136/bmjgast-2020-000476] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 10/07/2020] [Accepted: 10/24/2020] [Indexed: 12/28/2022] Open
Abstract
Objective To examine real-world treatment persistence, colectomy-free survival and treatment switching patterns in UK patients with ulcerative colitis (UC) prescribed golimumab or adalimumab. Design This was a retrospective chart review study in adult patients diagnosed with UC using data from 16 National Health Service sites in the UK. Patient records were included in the study if they had initiated first or second-line adalimumab or golimumab between 1 March 2016 and 30 September 2017 (index date). Subjects were required for ≥6 months post treatment initiation. Demographics, clinical characteristics, treatment-related data and colectomy data were extracted over a follow-up period of 6–12 months. Treatment persistence rate was the primary outcome. Colectomy-free survival and treatment switching were secondary outcomes. Outcomes were compared between treatments using χ2 tests and Fisher’s exact test for categorical variables. The t-tests were used for continuous variables. Time-to-event variables were evaluated using Kaplan-Meier curves and log-rank tests. Results The study included a total of 183 patients (96 (52.5%) prescribed adalimumab; 87 (47.5%) golimumab), and patients were mostly first line (79.8%). Demographic and clinical characteristics were generally similar between treatment groups. Persistence rates within 12 months were 64.6% for adalimumab and 64.4% for golimumab (p=0.681). Overall, 20.2% switched to other therapy within 1 year, with 8.2% golimumab and 12.0% adalimumab switching to another biologic. Of patients prescribed adalimumab, 14.6% had ≥1 dose change, mainly dose escalations. In the 12 months post treatment initiation, 8.2% of patients underwent colectomy, with no significant difference in colectomy-free survival by treatment, p=0.73. Conclusion This study provides evidence of clinical outcomes and real-world persistence for adalimumab and golimumab in UC. The persistence rates of both therapies were above 64.0% at 12 months following treatment initiation. In addition, the 1-year colectomy-free survival was relatively similar between the two treatments.

Abstract
Golimumab has demonstrated its long-term efficacy and safety in ulcerative colitis in clinical trials, but no data of long-term persistence has been published from real world. To estimate long-term persistence of golimumab, as well as factors associated with longer persistence, in patients with ulcerative colitis in real life. Observational multicentre study including adult patients with ulcerative colitis treated with golimumab and with at least twelve months of follow-up. We included 190 patients, 105 (55.26%) naive to anti-TNF, with mean disease duration of 9.32 ± 8.09 years. Probability of persistence was 63%, 46%, 39% and 27% at 1, 2, 3 and 4 years, respectively. Persistence was lower in patients with primary failure to previous anti-TNF. Eighty-two (43.16%) patients needed dose intensification during follow-up, with a mean time until intensification of 8.03 ± 8.64 months. Dose intensification and lower disease duration predicted higher persistence with golimumab (p = 0.037 and p = 0.008, respectively). During a follow-up of 17.25 ± 15.83 months, 32 (16.5%) patients needed hospitalisation and 11 (6%) underwent colectomy. No unexpected adverse events were reported. Golimumab has demonstrated good persistence and safety profile for long treatment in ulcerative colitis patients.

Abstract
Immune-mediated inflammatory diseases (IMIDs) are chronic conditions that create a significant disease burden on millions of patients while adding a major financial burden to societies and healthcare systems. The introduction of biologic medicines has contributed majorly to improving the clinical outcomes of IMIDs and as such these modalities have gained first- or second-line positions in a wide range of treatment guidelines from different international clinical societies. However, the high cost of these biologics traditionally limited their accessibility and delayed their initiation, leaving millions of patients with unmet medical needs for a more affordable and sustainable solution. The introduction of cost-efficient biosimilar anti-TNFs within Europe since 2013 has allowed more patients with IMIDs to access biologic therapies earlier and for longer, potentially altering the course of the disease into a milder phenotype and reducing the long-term disease burden. This review provides the latest evidence for the impact of biosimilars on patient outcomes and demonstrates their clinical value beyond a reduction in price.

Abstract
BACKGROUND AND AIM It is unclear how adding an anti-tumor necrosis factor alpha agent to immunomodulator (IM) treatment, as a step-up strategy, affects long-term outcomes in ulcerative colitis. This retrospective study investigated persistence associated with biologic anti-tumor necrosis factor alpha agents combined with IMs versus biologic monotherapy in patients with ulcerative colitis. METHODS This was a longitudinal cohort study of patients in the Japan Medical Data Center claims database who had been newly prescribed infliximab or adalimumab as induction (completed) and maintenance (2010-2016). Biologic persistence (i.e. no switch/discontinuation during maintenance) was compared among patients prescribed biologic monotherapy (Bio) and those prescribed a biologic combined with an IM, as step-up (Bio + prior IM) or simultaneously (Bio + IM). RESULTS Three hundred and sixty-nine eligible patients were analyzed (233, 78, and 58 in the Bio, Bio + prior IM, and Bio + IM subgroups, respectively). Multivariate analysis showed a lower probability of nonpersistence during maintenance for infliximab-treated patients in the Bio + prior IM versus Bio subgroup (hazard ratio: 0.53; 95% confidence interval: 0.29-0.99; P = 0.045). No such effect was seen in adalimumab-treated patients (P = 0.222) or in the overall population (P = 0.398). The probability of nonpersistence during maintenance in the Bio + IM subgroup was not significantly different from that in the Bio subgroup in either the biologic subpopulation or in the overall population. CONCLUSIONS Adding infliximab to an existing IM results in a lower probability of nonpersistence compared with infliximab monotherapy in ulcerative colitis patients. This effect is not seen in adalimumab-treated patients.

Abstract
OBJECTIVE Medication adherence is crucial in the management of Crohn's disease (CD), and yet the adherence remains low. This study aimed to develop machine learning models that can help predict CD patients of nonadherence to azathioprine (AZA), and thus assist caregivers to streamline the intervention process. METHODS This single-centered, cross-sectional study recruited 446 CD patients who have been prescribed AZA between Sep 2005 and Sep 2018. Questionnaires of medication adherence, anxiety and depression, beliefs of medication necessity and concerns, and medication knowledge were provided to patients, while other data were extracted from the electronic medical records. Two machine learning models of back-propagation neural network (BPNN) and support vector machine (SVM) were developed and compared with logistic regression (LR), and assessed by accuracy, recall, precision, F1 score and the area under the receiver operating characteristic curve (AUC). RESULTS The average classification accuracy and AUC of the three models were 81.6% and 0.896 for LR, 85.9% and 0.912 for BPNN, and 87.7% and 0.930 for SVM, respectively. Multivariate analysis identified four risk factors associated with AZA nonadherence: medication concern belief (OR=3.130, p<0.001), education (OR=2.199, p<0.001), anxiety (OR=1.549, p<0.001) and depression (OR=1.190, p<0.001), while medication necessity belief (OR=0.004, p<0.001) and medication knowledge (OR=0.805, p=0.013) were protective factors. CONCLUSION We developed three machine learning models and proposed an SVM model with promising accuracy in the prediction of AZA nonadherence in Chinese CD patients. The study also reconfirmed that education, psychologic distress, and medication beliefs and knowledge are correlated to AZA nonadherence.

Abstract
Background and objectives: Despite the serious concerns of patients about the role of food in triggering or ameliorating their intestinal disease, there are few studies dealing with patients’ beliefs and practices regarding diet in inflammatory bowel disease (IBD). The aim of this study was to investigate how the disease affected the dietary habits of patients with IBD, and to assess if patients’ food restrictions were responsible for low bone mineralization. Materials and Methods: For this study, 90 consecutive patients referred for IBD were interviewed regarding their dietary habits. Demographic features and clinical characteristics potentially associated with the dietary habits were collected. A validated and self-administered survey questionnaire dealing with dietary habits and patients’ beliefs and perceptions regarding food was analyzed. Multivariate logistic regression analysis was performed in order to identify risk factors for dietary restrictions among participants and to evaluate the relationship between dietary restrictions and low bone mineral density (BMD). Results: Among the 63 (70%) patients who claimed a self-prescribed dietary restriction, 84% avoided dairy products. Significant risk factors (adjusted odds ratio (OR), 95% confidence interval (CI)) for the dietary restrictions were a younger age (p = 0.02), a higher level of education (p = 0.007), and a higher visceral sensitivity index (p = 0.009). Most (80%) of the patients displayed an inadequate calcium intake, and an abnormal result at dual-energy X-ray absorptiometry (DXA) scan accounting for low BMD was reported in 46 (51%) of them. Dietary restrictions (p = 0.03), and in particular avoiding dairy products (p = 0.001), were significant risk factors for a low BMD, along with female gender (p = 0.001), smoking (p = 0.04), and steroid abuse (p = 0.03). Almost all (86%) patients changed their diet after IBD diagnosis, as 8% believed that foods could have been a trigger for IBD and 37% that a proper diet was more important than drugs in controlling disease. Although 61% of the patients claimed to have received nutritional advice, 78% of the participants showed interest in receiving more. Conclusions: Dietary habits of IBD patients should be investigated by healthcare professionals as part of the routine visit. Clinicians are invited to provide nutritional recommendations to these patients in order to avoid unnecessary self-prescribed dietary restrictions.
