Adalimumab vs Infliximab in Pediatric Patients With Crohn's Disease: A Propensity Score Analysis and Predictors of Treatment Escalation. Clin Transl Gastroenterol 2022; 13:e00490. [PMID: 35363628 PMCID: PMC9132518 DOI: 10.14309/ctg.0000000000000490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 03/04/2022] [Indexed: 11/21/2022] Open
Abstract
INTRODUCTION Two antitumor necrosis factor therapies (infliximab [IFX] and adalimumab [ADA]) have been approved for the treatment of pediatric Crohn's disease (CD) but have not been compared in head-to-head trials. The aim of this study was to compare the efficacy and safety of ADA and IFX by propensity score matching in a prospective cohort of pediatric patients with luminal CD and at least a 24-month follow-up. METHODS Among 100 patients, 75 met the inclusion criteria, and 62 were matched by propensity score. We evaluated time to treatment escalation as the primary outcome and primary nonresponse, predictors of treatment escalation and relapse, serious adverse events, pharmacokinetics, and effect of concomitant immunomodulators as secondary outcomes. RESULTS There was no difference between ADA and IFX in time to treatment escalation (HR = 0.63 [95% CI 0.31-1.28] P = 0.20), primary nonresponse (P = 0.95), or serious adverse events. The median (interquartile range) trough levels at the primary outcome were 14.05 (10.88-15.40) and 6.15 (2.08-6.58) µg/mL in the ADA and IFX groups, respectively. On a multivariate analysis, the combination of anti-Saccharomyces cerevisiae antibody negativity and antineutrophil cytoplasmic antibody positivity was a strong independent predictor of treatment escalation (HR 5.19, [95% CI 2.41-11.18], P < 0.0001). The simple endoscopic score for CD, L3 disease phenotype, and use of concomitant immunomodulators for at least the first 6 months revealed a trend toward significance on a univariate analysis. DISCUSSION Propensity score matching did not reveal substantial differences in efficacy or safety between ADA and IFX. The anti-S. cerevisiae antibody negativity and antineutrophil cytoplasmic antibody positivity combination is a strong predictor of treatment escalation.

J Clin Med 2021; 10:2132. [PMID: 34069295 PMCID: PMC8156358 DOI: 10.3390/jcm10102132] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 05/07/2021] [Accepted: 05/07/2021] [Indexed: 02/06/2023] Open
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
AIMS This study's objectives were to examine and compare the cost-effectiveness of biologic and non-biologic therapies in the improvement of the health-related quality of life (HRQoL) of patients with inflammatory bowel disease (IBD) in Saudi Arabia. MATERIALS AND METHODS This retrospective cohort study analyzed data from the medical records of patients with IBD treated at a tertiary-care hospital in Riyadh, Saudi Arabia. Drug utilization costs and HRQoL scores were evaluated at baseline and after six months of treatment. Patients' HRQoL was measured using the Arabic version of the standardized EuroQol 5 Dimensional 3 Level (EQ-5D-3L) questionnaire with a visual analog scale (VAS). RESULTS Eighty-seven patients with Crohn's disease (CD) and 69 patients with ulcerative colitis (UC) were included in the study (N = 156), and 59 (37.82%) were treated with biologics. Similar effects of both types of medications were found on the HRQoL domains of mobility, usual activities, and pain and discomfort, while biologics outperformed non-biologics on the self-care domain. The mean utilization cost of a biologic-based treatment over a six-month period was SAR 25,690.46 (USD 6,850.79) higher than that of the non-biologic treatment (95% confidence interval (CI): 24,548.55-27,465.11), and the change in the ED-5D-3L VAS score from baseline to follow-up was 4.78 points (95% CI: 1.96-14.00). A probabilistic sensitivity analysis demonstrated that IBD therapy with biologic-based treatment is always more expensive, but also more effective in improving HRQoL 99.45% of the time. Adalimumab was found to be less cost effective than infliximab in the management of CD. LIMITATIONS Information bias cannot be ruled out, as this investigation was a retrospective cohort study with a relatively small sample that was not randomized. CONCLUSIONS The results of this analysis can serve as a foundation to introduce HRQoL-based recommendations for the use of biologics in the management of IBD in Saudi Arabia.

Inflamm Bowel Dis 2019; 25:1462-1473. [PMID: 30689858 DOI: 10.1093/ibd/izy399] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 12/02/2018] [Accepted: 12/20/2018] [Indexed: 12/23/2022]
Abstract
BACKGROUND Medication costs in inflammatory bowel disease (IBD) are now the principal driver of health care costs. Cost-effective strategies to optimize and rationalize treatment are therefore necessary. METHODS A systematic review until April 30, 2018, was performed to identify economic evaluations of strategies to optimize infliximab, adalimumab, and immunomodulators for the treatment of IBD in adults. A qualitative synthesis of the identified studies was performed. RESULTS Seventy articles were identified that met the inclusion criteria. Adalimumab seems cost-effective compared with infliximab as maintenance therapy for moderate to severe Crohn's disease (CD). Infusion costs are a significant additional treatment cost with infliximab. However, other studies found biosimilar infliximab more cost-effective than alternative biologics in fistulizing and moderate-severe luminal CD-although the latter did not reach a willingness-to-pay threshold of <$50,000. In moderate-severe ulcerative colitis, infliximab seems more cost-effective than adalimumab. Multiple tailored approaches to treatment based on objective markers of disease activity or efficacy have been shown to be cost-effective in CD, including following secondary loss of response to anti-TNF therapy for postoperative recurrence and in escalating treatment. For immunomodulator treatment, both thiopurine methyltransferase (TPMT) testing before commencing thiopurines and thiopurine metabolite testing for dose optimization seem cost-effective. CONCLUSION In a win-win for patients and payers, several potential avenues to achieve cost-effectiveness-but also therapeutic optimization of anti-TNF therapies-were elucidated in this review with comparatively sparse data for immunomodulators. Optimizing immunomodulator and anti-tumor necrosis factor alpha therapy to achieve objective disease control seems to be cost-effective at conventional willingness-to-pay thresholds in a number of clinical settings.

Abstract
AIMS Increasing use of biologics has led to interest in treatment components with potential for cost savings. This study was aimed at comparing administration times and associated costs of infliximab and vedolizumab infusions for inflammatory bowel disease (IBD). MATERIALS AND METHODS This study used claims data from the Symphony Health Integrated Dataverse to identify IBD patients using infliximab or vedolizumab between 20 May 2014 and 29 February 2016. Use of Current Procedural Terminology administration codes was evaluated and costs calculated using the 2016 Center for Medicare and Medicaid Services Physician Fee Schedule. Assessments included infusion times, associated costs, productivity loss using average wage estimates from the United States Bureau of Labor Statistics, and home infusion adoption. RESULTS A total of 10,051 infliximab and 3114 vedolizumab patients with first-hour claims were identified; 52.0% were female and 64.5% had Crohn's disease. There were 48,377 infliximab first-hour claims (mean 4.8 infusions per patient); 46,462 (96.0%) had a second-hour claim. In comparison, there were 14,717 vedolizumab claims (mean 4.7 infusions per patient), with only 411 (2.8%) second-hour claims, resulting in vedolizumab cost savings of approximately $1.27 million. The difference in second-hour infusions resulted in 46,051 additional hours of productivity loss with infliximab, and lost wages averaging $1.18 million (range $0.68-$1.77 million). LIMITATIONS Administration costs were inferred as charge costs and not directly assessed. Productivity loss assessed time spent on infusion only, and included a small proportion of patients beyond working age. CONCLUSIONS Second-hour infusion billing was significantly lower with vedolizumab than with infliximab, corresponding to cost savings and reduced productivity loss.

Abstract
Background Although many clinical trials have been conducted in treatments of Crohn’s disease (CD), whether the trial results were representative of daily practice needs to be supported by studies conducted in real-world settings. Aim This study aims to identify how CD is treated and what are the clinical effectiveness and safety of the pharmaceutical therapies of CD in real-world settings. Methods A systematic literature review was conducted based on Medline®, Embase®, and Cochrane. All publications were assessed for title/abstract and full-text according to a predefined study protocol. Data were extracted and reported. Results A total of 1,998 publications were identified. Fifty studies including six publications reporting treatment pattern and 44 studies reporting clinical effectiveness and safety of pharmaceutical therapies in CD management in Europe were included. 5-Aminosalicylic acid and corticosteroids were reported to be used among 14%–74% of CD patients. Immunomodulators were used by 14%–25% and 29%–31% of CD patients as an initial and follow-up treatment, respectively. Biological therapies were used by 25%–33% of CD patients. A trend toward an increasing use of immunomodulators and biological therapies in Europe has been reported in recent years. Approximately 50% of patients achieved remission on immunomodulator or biologic treatment, although a relapse rate of up to 23% has been reported. Conclusion There is a trend of treatment shift to immunomodulators and biologics in CD management. Clinical effectiveness of immunomodulators and biologics has been demonstrated, though with a lack of sustainability of the effectiveness.

Abstract
BACKGROUND Early initiation of tumor necrosis factor-alpha inhibitor (TNFI) therapy for children and young adults with inflammatory bowel disease (IBD) is not well described. METHODS We conducted a retrospective cohort study of children and young adults (≤24 yr) newly diagnosed with IBD using health insurance claims from 2009 to 2013. The conventional "step-up" approach was defined as TNFI initiation >30 days after first IBD medication prescription, whereas the "top-down" approach was defined as new TNFI prescription within 30 days of first IBD medication prescription. Switching rates, time to initiation, discontinuation, and adherence to TNFIs were compared between the 2 strategies. RESULTS A total of 11,962 IBD patients were identified. Among 3300 TNFI users, 1298 (39.3%) were treated with the top-down approach, whereas 2002 (60.7%) were treated with the step-up approach. Top-down approach use increased from 31.4% to 49.8% during the 5-year period, and under this approach, most patients were treated with TNFIs alone. Time to TNFI initiation was shorter for patients diagnosed in more recent years. Patients treated with the top-down strategy had lower rates of corticosteroid use (32.5% versus 94.2%) compared with step-up treatment but presented a higher rate of TNFI discontinuation. The 2 strategies both exhibited high adherence (mean proportion of days covered: 83.7%-95.4%). CONCLUSIONS Early TNFI initiation increased over time for children and young adults with IBD and was related to lower rates of corticosteroid use compared with the conventional approach. However, the higher rate of TNFI discontinuation under the top-down approach requires further examination.

Abstract
BACKGROUND & AIMS There are limited data on the effects of discontinuing infliximab therapy for Crohn's disease (CD). We investigated the long-term outcome of patients with CD who discontinued infliximab while in clinical remission, and searched for prognostic markers of continued remission after infliximab cessation. METHODS We performed a retrospective, single-center study of 100 patients with CD who discontinued infliximab upon achieving clinical remission; 84 patients continued immunomodulator therapy. Clinical and endoscopic data were retrieved from a medical database in Belgium, and patients were followed up through April 2013 (median, 9.7 y; interquartile range, 8-11.5 y). Sustained clinical remission (SCR) was defined as maintenance of disease remission, without escalation in medical therapy or CD-related surgeries, until the end of the follow-up period. We measured trough concentrations of infliximab, antibodies to microbial antigens, and circulating inflammatory markers in serum samples collected before treatment and at the time of infliximab discontinuation. RESULTS At the end of the follow-up period, 52 patients had SCR. Univariate (log-rank) analysis associated SCR with patient age at diagnosis (≥25 y; P = .012) and disease duration (<1 y; P = .017). Among factors evaluated at the time of infliximab discontinuation, infliximab trough concentrations (<6 μg/mL; P = .031), complete mucosal healing (P = .046), and serum positivity for vascular cell adhesion molecule-1 (>0.67 μg/mL; P = .024) were associated with SCR. In multiple Cox proportional hazards regression analysis, only age at diagnosis of 25 years and older was associated independently with SCR (hazard ratio, 1.83; 95% confidence interval, 1.03-3.25; P = .04). CONCLUSIONS In a large, real-life study, 52% of patients with CD who discontinued infliximab upon achieving clinical remission remained in SCR after a median period of approximately 10 years; Most patients remained on immunomodulator therapy. Although patients with CD have variable responses to infliximab, a subgroup achieved long-term remission after infliximab discontinuation.

METHODS We retrospectively compared three different regimens adopted in our outpatient infusion unit from 2010 to 2013: Group 1, a standard procedure with two-hour infusions, preceded by hydrocortisone medication (87 patients, 311 infusions); Group 2, a similar regimen without physician supervision (130 patients, 464 infusions); Group 3, a one-hour nurse-led procedure without routine premedication (176 patients, 1356 infusions). Disease characteristics, infusion reactions, infusions per month and patients' satisfaction were recorded. RESULTS There were significantly fewer infusion reactions in Group 3 than Group 1 (2.2% versus 5.8% respectively; p=0.001). The only significant risk factor for side effects was premedication (odds ratio 4.71, 95% confidence interval 2.21-10.02, p<0.001) which was related to the presence of previous side effects. Number of infusions per month increased by 27% (83 versus 61, p<0.001) without increasing nurses' workload and patients were satisfied. CONCLUSIONS Our fast nurse-led procedure was well tolerated, effective and satisfactory for patients.

Pariente B, Laharie D. Review article: why, when and how to de-escalate therapy in inflammatory bowel diseases. Aliment Pharmacol Ther 2014; 40:338-53. [PMID: 24957164 DOI: 10.1111/apt.12838] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2013] [Revised: 12/01/2013] [Accepted: 05/25/2014] [Indexed: 02/06/2023]
Abstract
BACKGROUND Therapeutic objectives are currently evolving in inflammatory bowel diseases (IBD) from control of symptoms towards improvement of long-term disease outcomes. In patients achieving remission, safety concerns - infections or neoplasia - and economic issues are prompting de-escalation strategies. AIM To give a complete overview of studies on de-escalating therapy in IBD. METHODS A structured search in Pubmed, the Cochrane Library and EMBASE was performed using defined key words (inflammatory bowel diseases, Crohn's disease, ulcerative colitis, immunosuppressants, azathioprine, methotrexate, anti-TNF, infliximab, adalimumab, de-escalation, dose reduction, cessation, stopping, withdrawal), including full text articles and abstracts in English language. RESULTS Eleven studies were identified, investigating cessation of immunosuppressants (IS) and/or anti-TNF treatments. Patients exposed to a combination of IS and anti-TNF have an increased risk for infections, especially due to opportunistic agent, without any clear signal for associated cancers when compared to those receiving single therapy. In patients receiving IS alone, relapse rate at 12 months following IS cessation is close to 20% and 30% in Crohn's disease (CD) and ulcerative colitis (UC) respectively. There is no study specifically evaluating anti-TNF treatment withdrawal in case of scheduled anti-TNF monotherapy in IBD. In patients receiving combination therapy with IS and infliximab (IFX) for at least 6 months, relapse rate of IFX failure following IS cessation is near to 20% at 24 months and seems to be similar in patients who maintained combination therapy. In case of anti-TNF therapy, cessation in CD patients in combo-therapy proportion of relapse is high, close to 40% and 50% over 1 year and 2 years respectively. Regarding higher risk of adverse events, some special situations - young males, pregnancy and elderly - should be managed specifically and de-escalating treatment considered. CONCLUSIONS De-escalating treatment strategy should be mainly considered in patients with high risk of severe adverse events and low relapse risk (patients in deep remission) after drug withdrawal. For these reasons, cessation of anti-TNF treatment and/or immunosuppressants should be a case by case decision in highly selected patients.

Systematic review with network meta-analysis: the efficacy of anti-TNF agents for the treatment of Crohn's disease. Aliment Pharmacol Ther 2014; 39:1349-62. [PMID: 24749763 PMCID: PMC7006346 DOI: 10.1111/apt.12749] [Citation(s) in RCA: 148] [Impact Index Per Article: 14.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2014] [Revised: 03/12/2014] [Accepted: 03/24/2014] [Indexed: 12/12/2022]
Abstract
BACKGROUND Anti-tumour necrosis factor-alpha agents (anti-TNF) are effective therapies for the treatment of Crohn's disease (CD), but their comparative efficacy is unknown. AIM To perform a network meta-analysis comparing the efficacy of anti-TNF therapies in CD. METHODS After screening 506 studies, reviewers extracted information on 10 studies. Traditional meta-analysis (TMA) was used to compare each anti-TNF agent to placebo. Bayesian network meta-analysis (NMA) was performed to compare the effects of anti-TNF agents to placebo. In addition, sample sizes for comparative efficacy trials were calculated. RESULTS Compared to placebo, TMA revealed that anti-TNF agents result in a higher likelihood of induction of remission and response (RR: 1.66, 95% CI: 1.17-2.36 and RR: 1.43, 95% CI: 1.17-1.73, respectively) as well as maintenance of remission and response (RR: 1.78, 95% CI: 1.51-2.09 and RR: 1.68, 95% CI: 1.46-1.93, respectively). NMA found nonsignificant trends between infliximab and adalimumab or certolizumab pegol. Among subcutaneous therapies, NMA demonstrated superiority of adalimumab to certolizumab pegol for induction of remission (RR: 2.93, 95% CrI: 1.21-7.75). Sample size calculations suggest that adequately powered head-to-head comparative efficacy trials would require greater than 3000 patients. CONCLUSIONS All anti-TNF agents are effective for induction and maintenance of response and remission in the treatment of CD. Although adalimumab is superior to certolizumab pegol for induction of remission, there is no evidence of clinical superiority among anti-TNF agents. Head-to-head trials among the anti-TNF agents are impractical in terms of size and cost.

Systematic review with network meta-analysis: the efficacy of anti-tumour necrosis factor-alpha agents for the treatment of ulcerative colitis. Aliment Pharmacol Ther 2014; 39:660-71. [PMID: 24506179 PMCID: PMC6979320 DOI: 10.1111/apt.12644] [Citation(s) in RCA: 91] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2013] [Revised: 12/22/2013] [Accepted: 01/11/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND Antibodies against tumour necrosis factor-alpha (anti-TNF) are effective therapies in the treatment of ulcerative colitis (UC), but their comparative efficacy is unknown. AIM To perform a network meta-analysis comparing the efficacy of anti-TNF agents in UC. METHODS After screening 506 studies, reviewers extracted information on seven studies. Traditional meta-analysis (TMA) was used to compare each anti-TNF agent to placebo. Bayesian network meta-analysis (NMA) was performed to compare the effects of anti-TNF agents to placebo. In addition, sample sizes for comparative efficacy trials were calculated. RESULTS Compared to placebo, TMA revealed that anti-TNF agents result in a higher likelihood of induction of remission and response (RR: 2.45, 95% CI: 1.72-3.47 and RR: 1.65, 95% CI: 1.37-1.99 respectively) as well as maintenance of remission and response (RR: 2.00, 95% CI: 1.52-2.62 and RR: 1.76, 95% CI: 1.46-2.14 respectively). Individually, infliximab, adalimumab and goliumumab resulted in a higher likelihood of induction and maintenance for both remission and response. NMA found nonsignificant trends in comparisons of the individual agents. The required sample sizes for direct head-to-head trials between infliximab and adalimumab for induction and maintenance are 174 and 204 subjects respectively. CONCLUSIONS This study demonstrates that, compared to placebo, infliximab, adalimumab and golimumab are all effective for the induction and maintenance of remission in ulcerative colitis. However, network meta-analysis demonstrates that no single agent is clinically superior to the others and therefore, other factors such as cost, safety, route of administration and patient preference should dictate our choice of anti-TNF agents. A randomised comparative efficacy trial between infliximab and adalimumab in UC is of practical size and should be performed.
