INTRODUCTION: Ustekinumab, an interleukin-12 and interleukin-23 antagonist, is licensed for the treatment of Crohn's disease (CD) and ulcerative colitis (UC) after the phase III trial programs demonstrated efficacy over placebo. However, these findings may not be directly transferable to the real-world due to the stringent inclusion criteria of clinical trials.
METHODS: We conducted a systematic review and meta-analysis of the safety and effectiveness of ustekinumab in inflammatory bowel disease (IBD). A systematic literature search was conducted via Medline and Embase from inception to April 21, 2020. Observational studies assessing ustekinumab's safety and effectiveness by reporting response, remission and/or adverse events (AE) in either CD or UC were included. Two reviewers independently assessed risk of bias and extracted study data. Random-effects meta-analysis was performed to pool rates of clinical response, remission, and safety data.
RESULTS: Following deduplication, 2147 records were identified of which 41 studies (38 CD, 3 UC) comprising 4400 patients were included for quantitative analysis. Pooled clinical remission rates for CD were 34% (95% CI, 26%-42%) following induction and 31% (95% CI, 25%-38%) at one year. For UC, post-induction clinical remission rates were 39% (95% CI, 23%-56%). Serious AEs were reported in 5.6% of patients. Pregnancy outcomes were similar to the general population. One-third of patients with active baseline perianal disease responded or had fistula healing with ustekinumab.
CONCLUSIONS: In the most comprehensive systematic review and meta-analysis to date, and the first to include UC, ustekinumab was shown to be effective and safe in the real-world treatment of IBD.
BACKGROUND & AIMS: There is debate over whether patients with inflammatory bowel diseases (IBD) treated with biologics that are not tumor necrosis factor antagonists (such as vedolizumab or ustekinumab) should receive concomitant treatment with immunomodulators. We conducted a meta-analysis to compare the efficacy and safety of concomitant immunomodulator therapy vs vedolizumab or ustekinumab monotherapy.
METHODS: In a systematic search of publications, through July 31, 2019, we identified 33 studies (6 randomized controlled trials and 27 cohort studies) of patients with IBD treated with vedolizumab or ustekinumab. The primary outcome was clinical benefit, including clinical remission, clinical response, or physician global assessment in patients who did vs did not receive combination therapy with an immunomodulator. Secondary outcomes were endoscopic improvement and safety. We performed random-effects meta-analysis and estimated odds ratio (OR) and 95% CIs.
RESULTS: Overall, combination therapy was not associated with better clinical outcomes in patients receiving vedolizumab (16 studies: OR, 0.84; 95% CI, 0.68-1.05; I2=13.9%; Q test P=.17) or ustekinumab (15 studies: OR, 1.1; 95% CI, 0.87-1.38; I2=11%; Q test P=.28). Results were consistent in subgroup analyses, with no difference in clinical remission or response in induction vs maintenance studies or in patients with Crohn's disease vs ulcerative colitis in studies of vedolizumab. Combination therapy was not associated with better endoscopic outcomes in patients receiving vedolizumab (3 studies: OR, 1.13; 95% CI, 0.48-2.68; I2=0; Q test P=.96) or ustekinumab (2 studies: OR, 0.58; 95% CI, 0.21-1.16; I2=47%; Q test P=.17). Combination therapy was not associated with an increase in adverse events during vedolizumab therapy (4 studies: OR, 1.17; 95% CI, 0.75-1.84; I2=0; Q test P=.110).
CONCLUSIONS: In a meta-analysis of data from studies of patients with IBD, we found that combining vedolizumab or ustekinumab with an immunomodulator is no more effective than monotherapy in induction or maintenance of remission.
BACKGROUND AND AIMS: Extraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel diseases (IBD) and a challenging condition to manage. Tumor necrosis factor alpha antagonists (anti-TNFα) are recognized as the primary therapeutic option. We aimed to summarize evidence on the efficacy of ustekinumab for the treatment of EIMs.
METHODS: We searched in PubMed, Cochrane Library, and Web of Science up to October 2020 all interventional and non-interventional studies published in English assessing ustekinumab efficacy for the treatment of EIMs.
RESULTS: Nine studies (8 retrospective and 1 prospective) were included, enrolling a total of 254 patients with IBD and EIM. Ustekinumab showed its effectiveness for arthralgia and psoriatic arthritis in 152 patients through 3 high quality studies. Conversely, no efficacy was found in axial spondyloarthritis. Psoriasis, pyoderma gangrenosum and erythema nodosum were assessed in 7 studies including 65 patients and showed high response rate to ustekinumab treatment. Promising results for aphthous stomatitis and uveitis were reported, but data were limited to 20 patients from 2 studies.
CONCLUSIONS: Ustekinumab showed to be an effective option for the treatment of EIMs, especially for dermatological and rheumatological manifestations. However, more data are needed to confirm the role of ustekinumab in this setting.
