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

BackgroundThe 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.AimTo provide real-world evidence on treatment effectiveness, tolerability and preferences of physicians and patients regarding various advanced therapies for IBD.MethodsWe 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.ResultsAmong 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).ConclusionThis 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. This systematic review and meta-analysis of 63 observational studies found that ustekinumab and vedolizumab had the highest 1-year persistence rates in Crohn's disease and ulcerative colitis, respectively. They outperformed traditional TNFi drugs like infliximab and adalimumab. However, certolizumab had the lowest persistence rates at 1 and 2 years.image
