Ustekinumab and Vedolizumab Are Equally Safe and Effective in Elderly Crohn's Disease Patients

Vedolizumab versus ustekinumab in Crohn's disease with prior anti-tumor necrosis factor failure: an updated meta-analysis

Ustekinumab and vedolizumab are key treatment options for Crohn's disease patients who fail anti-tumor necrosis factor (TNF) therapy. This updated meta-analysis aims to compare the efficacy and safety of these two drugs. We performed a systematic review in PubMed, Embase , and Cochrane databases searching for randomized and nonrandomized studies comparing vedolizumab versus ustekinumab in patients with Crohn's disease with previous anti-TNF failure or intolerance. The primary outcome was steroid-free clinical remission (SFR) at the pos-induction (12-16 weeks) and maintenance period (48-52 weeks). The odds ratio (OR) was used for binary outcomes with their respective 95% confidence interval (CI). Heterogeneity was assessed using the Cochran Q test and I2 statistics. This meta-analysis included 11 studies and 2724 patients. There was a significant difference favoring ustekinumab in SFR at pos-induction (OR, 1.44; 95% CI, 1.11-1.88; P  = 0.006; I2  = 27%) and maintenance periods (OR, 1.86; 95% CI, 1.23-2.82; P  = 0.003; I2  = 80%), in clinical remission at pos-induction period (OR, 2.04; 95% CI, 1.58-2.63; P  < 0.001; I2  = 3%), and in treatment discontinuation due to adverse events (OR, 0.31; 95% CI, 0.16-0.60; P  < 0.001; I2  = 0%). In patients with Crohn's disease with prior anti-TNF failure, ustekinumab showed higher SFR during both the pos-induction and maintenance period and a lower rate of treatment discontinuation due to adverse events.

Meta-analysis: Persistence of advanced therapies in the treatment of inflammatory bowel disease

BACKGROUND

The expanding options in advanced therapies for ulcerative colitis (UC) and Crohn's disease (CD) present challenges in treatment selection. Persistence analysis assesses drug durability in real-world settings, acting as a surrogate marker for medication efficacy and tolerance. Unlike traditional comparative studies, persistence analysis provides insights extending beyond the initial year of treatment.

AIM

To provide real-world evidence on treatment effectiveness, tolerability and preferences of physicians and patients regarding various advanced therapies for IBD.

METHODS

We conducted a systematic review of observational studies up to March 2023 assessing advanced therapies' persistence in UC and CD. Advanced therapies under examination included infliximab, adalimumab, vedolizumab, ustekinumab, golimumab, certolizumab and tofacitinib. We pooled the persistence of each agent and conducted a meta-analysis to compare the persistence of newer agents with traditional TNF inhibitors (TNFi)-specifically infliximab and adalimumab.

RESULTS

Among 63 observational studies, vedolizumab had the highest 1-year persistence in UC (73.8%, 95% CI: 70.0%-77.6%) and ustekinumab in CD (77.5%, 95% CI: 72.9%-82.1%). Compared to TNFi, vedolizumab demonstrated increased persistence with a relative risk (RR) of 1.30 (95% CI: 1.19-1.41) for UC and 1.14 (95% CI: 1.09-1.20) for CD at 1 year, while ustekinumab demonstrated a RR of 1.15 (95% CI: 1.07-1.23) for CD at 1 year. Vedolizumab exhibited sustained increased persistence in UC over 2 years compared to TNFi (RR: 1.33, 95% CI 1.14-1.54).

CONCLUSION

This meta-analysis highlights the superior persistence of ustekinumab and vedolizumab over TNFi, and offers valuable insights for clinicians navigating the challenging landscape of UC and CD therapeutic choices.

Inflammatory Bowel Diseases in the Elderly: A Focus on Disease Characteristics and Biological Therapy Patterns

Background: The incidence of inflammatory bowel diseases (IBDs) in elderly patients is constantly increasing. It results from the combination of an aging population with compounding prevalence of IBD, as well as the growing burden of elderly-onset IBD. The clinical characteristics of elderly patients differ from young subjects with IBD due to the multimorbidity or polypharmacy, affecting the choice of adequate therapeutic options. The aim of this study was to determine the clinical aspects and biological therapy safety in elderly Polish IBD patients. Methods: We conducted a retrospective study aimed at describing the demographic, clinical, and management characteristics of IBD patients treated with a biological therapy in two referral centers within the National Drug Program in Poland. Results: Out of the entire group of 366 studied patients, 51 (13.9%) were aged over 60-32 with ulcerative colitis (UC) and 19 with Crohn's disease (CD). The disease location was predominantly ileocolonic (57.89%) in patients with CD and pancolitis for patients with UC (56.25%). Most of the elderly IBD subjects were characterized by significant comorbidities, with Charlson Comorbidity Index (CCI) ≥ 1 in 66.67% patients. The probability of stopping biological therapy due to adverse events had the tendency to be higher in the CCI ≥ 1 group (20.58% vs. 5.88% in CCI = 0; p = 0.087). The main reasons for the therapy discontinuation included hypersensitivity reactions and liver enzyme abnormalities. Conclusions: In conclusion, our results underline the importance of assessing the comorbidity status instead of the age prior to initiating biological therapy, analyzing additional safety risks, and close monitoring in IBD patients with multiple comorbidities.

Comparing clinical trial population representativeness to real-world users of 17 biologics approved for immune-mediated inflammatory diseases: An external validity analysis of 66,639 biologic users from the Italian VALORE project

To date, no population-based studies have specifically explored the external validity of pivotal randomized clinical trials (RCTs) of biologics simultaneously for a broad spectrum of immuno-mediated inflammatory diseases (IMIDs). The aims of this study were, firstly, to compare the patients' characteristics and median treatment duration of biologics approved for IMIDs between RCTs' and real-world setting (RW); secondly, to assess the extent of biologic users treated for IMIDs in the real-world setting that would not have been eligible for inclusion into pivotal RCT for each indication of use. Using the Italian VALORE distributed database (66,639 incident biologic users), adult patients with IMIDs treated with biologics in the Italian real-world setting were substantially older (mean age ± SD: 50 ± 15 years) compared to those enrolled in pivotal RCTs (45 ± 15 years). In the real-world setting, certolizumab pegol was more commonly used by adult women with psoriasis/ankylosing spondylitis (F/M ratio: 1.8-1.9) compared to RCTs (F/M ratio: 0.5-0.6). The median treatment duration (weeks) of incident biologic users in RW was significantly higher than the duration of pivotal RCTs in almost all indications for use and most biologics (4-100 vs. 6-167). Furthermore, almost half (46.4%) of biologic users from RW settings would have been ineligible for inclusion in the respective indication-specific pivotal RCTs. The main reasons were: advanced age, recent history of cancer and presence of other concomitant IMIDs. These findings suggest that post-marketing surveillance of biologics should be prioritized for those patients.

Efficacy and Safety of Biological Therapies and JAK Inhibitors in Older Patients with Inflammatory Bowel Disease

With the introduction of more and more monoclonal antibodies selectively targeting various mediators of the immune system, together with Janus-Kinase (JAK)-inhibitors with variable affinities towards different JAK subtypes, the available therapeutic options for the treatment of inflammatory bowel diseases (IBD) have undergone an acceleration in the last five years. On the other hand, the prevalence of IBD patients over 65-years-old is steadily increasing, and, with this, there is a large population of patients that presents more comorbidities, polypharmacy, and, more frequently, frailty compared to younger patients, exposing them to potentially major risks for adverse events deriving from newer therapies, e.g., infections, cardiovascular risks, and malignancies. Unfortunately, pivotal trials for the commercialization of new therapies rarely include older IBD patients, and those with serious comorbidities are virtually excluded. In the present review, we focus on existing literature from pivotal trials and real-world studies, analyzing data on efficacy/effectiveness and safety of newer therapies in older IBD patients with special emphasis on comorbidities and frailty, two distinct but intercorrelated aspects of the older population since age by itself seems to be of minor importance.

Clinical characteristics of elderly-onset inflammatory bowel disease

Inflammatory bowel disease (IBD) is a group of chronic non-specific intestinal inflammatory diseases whose etiology has not been elucidated. The prevalence of elderly-onset IBD is increasing; however, its disease phenotype, pathophysiology, and clinical characteristics are different from those of adult-onset IBD. In order to better manage elderly IBD patients, it is becoming increasingly important to accurately describe the unique characteristics of elderly-onset IBD. Therefore, this article, based on the domestic and foreign literature reports from 2017 to now, describes the characteristics of elderly-onset IBD with regard to pathogenesis, epidemiological characteristics, clinical features, and treatment.
