Abstract

OBJECTIVE: To compare real-world treatment persistence, dose escalation, rates of opportunistic or serious infections, and healthcare costs in patients with Crohn's disease (CD) receiving vedolizumab (VDZ) vs ustekinumab (UST) in the United States.

METHODS: A retrospective observational study in adults with CD initiated on VDZ or UST on/after 26 September 2016, was performed using the IBM Truven Health MarketScan databases (1 January 2009-30 September 2018). Rates of treatment persistence, dose escalation, opportunistic or serious infection-related encounters, and healthcare costs per patient per month (PPPM) were evaluated. Entropy balancing was used to balance patient characteristics between cohorts. Event rates were assessed using weighted Kaplan-Meier analyses and compared between cohorts using log-rank tests. Healthcare costs were compared between cohorts using weighted 2-part models.

RESULTS: 589 VDZ and 599 UST patients were included (172 [29.2%] and 117 [19.5%] were bio-naïve, respectively). After weighting, baseline characteristics were comparable between cohorts. No significant difference in rates of treatment persistence (12-month: VDZ, 76.5%; UST, 82.1%;

CONCLUSIONS: In this real-world study, similar treatment persistence, dose escalation, and rates of opportunistic or serious infections were observed with VDZ- and UST-treated patients with CD. However, VDZ was associated with a significantly lower cost outlay for healthcare systems.
