Abstract

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.
