This study seeks to compare the persistence of biologic drugs among patients with inflammatory bowel disease (IBD). METHODS:Patients with newly diagnosed IBD were included in a retrospective study using Truven MarketScan database. Treatment persistence and switching was compared among biologic medications including infliximab, adalimumab, certolizumab, golimumab, and vedolizumab. Predictors for discontinuation and switching were evaluated using time-dependent propor
