Abstract

Introduction

Reported rates of extraintestinal manifestations (EIMs) in patients (pts) with Crohn’s disease (CD) are 37%–55%.1,2 This post hoc exploratory analysis investigated the effect of vedolizumab (VDZ) treatment on existing and new EIMs in patients with CD enrolled in GEMINI 2 (NCT00783692).

Method

Outcomes were sustained resolution of existing EIMs (absence of symptoms, sustained to study end), worsening of existing EIMs and occurrence of new EIMs. For arthritis/arthralgia (ar/ar), Kaplan–Meier estimates were used to describe ‘time to sustained resolution’. A multivariate Cox regression adjusting for confounding factors was conducted. The effect of steroid tapering on new or worsening ar/ar was explored, using prednisone equivalent dose (≤30 mg) as a time-dependent covariate.

Results

Pts received VDZ (n=814), VDZ/placebo (VDZ/PLA: VDZ to Week 6, PLA Weeks 6–52; n=153) or PLA only (n=148). Rates of EIMs other than ar/ar were too low for further analysis. Predicted annual rates of sustained resolution of ar/ar were 51% (VDZ), 41% (VDZ/PLA) and 36% (PLA). VDZ pts were 32% more likely to achieve sustained resolution of ar/ar versus PLA pts, and 21% less likely to have a worsening/new occurrence (Table, both non-significant [NS]). In pts receiving corticosteroids (CS; n=530), adjustment for CS withdrawal resulted in an ~4% increased likelihood of new or worsening ar/ar in all groups (30 mg dose reduction hazard ratio [HR] 1.04 [95% CI: 0.67–1.60], NS). Hazard reduction for the VDZ groups versus PLA was similar (VDZ, 0.73 [95% CI: 0.44–1.22], NS; VDZ/PLA, 0.72 [95% CI: 0.37–1.39], NS).

Conclusion

In this post hoc exploratory analysis, there were trends for both a reduced incidence of new or worsening ar/ar and an increased rate of sustained resolution of ar/ar in pts receiving VDZ. CS tapering increased the probability of ar/ar in all groups.
