Background
“Real-life” data of retention rate and persistence of adalimumab in inflammatory bowel disease are still limited.
Aims
To analyze retention rate, persistence, and safety of adalimumab in a 9-year real-life cohort of inflammatory bowel disease patients.
Methods
In this observational, retrospective single-center study, all adult patients treated with adalimumab as the first- and second-line biological treatment for steroid-dependent or refractory inflammatory bowel disease between March 2008 and March 2017 were included. Primary outcomes were persistence, retention rate, and adverse events; the secondary outcome was the identification of predictors of withdrawal.
Results
Ninety-six out of 181 patients (53%) withdrew their first course of adalimumab. The retention rate was 47% and 46.9% in Crohn’s disease and ulcerative colitis patients, respectively; median persistence was 26 and 24 months in CD and UC patients, respectively. The cumulative probability of treatment persistence was 80.2%, 54.5%, and 29.6% and 69.6%, 40.4%, and 21.5% in CD and UC patients, respectively. The incidence rate of any adverse event was 12.5/100 patients-year; severe adverse events were 1.7/100 patients-year. The Cox regression revealed that CD patients with baseline disease duration > 72 months have a higher likelihood for withdrawal due to failure and/or adverse events (HR 1.62, 95% CI 1–2.62, p = 0.04); no predictors of discontinuation were found in UC.
Conclusions
Adalimumab showed a great persistence in the first 12 months of therapy and excellent safety profile. Early treatment of CD patients could increase efficacy and reduce the adverse event rate.
