Abstract

Background & aims: Comparative effectiveness has become increasingly important to help position therapies for inflammatory bowel disease. We compared the efficacy and rapidity of onset of action of infliximab vs ustekinumab induction therapy for moderate to severe biologic-naïve Crohn's disease (CD) using patient-level data from randomized controlled trials.

Methods: This was a post hoc analysis of 2 large CD clinical trial programs that included data on 420 biologic-naïve CD patients. Differences in proportions of patients achieving week 6 clinical remission, clinical response, and normalization of calprotectin were compared. Multivariate logistic regression was used to adjust for confounders. Sensitivity analysis was conducted using propensity scores to create a cohort of matched participants with similar distribution of baseline covariates.

Results: At week 6, a comparable number of patients achieved clinical remission with infliximab compared with patients treated with ustekinumab (44.9% vs 37.9%; adjusted odds ratio [aOR], 1.22; 95% CI, 0.79-1.89). Similarly, at week 6 the clinical response rates were not significantly different (58.4% infliximab vs 54.9% ustekinumab; aOR, 1.25; 95% CI, 0.82-1.90). No significant difference was observed between treatment groups for achieving a week 6 fecal calprotectin level less than 250 mcg/L in those with increased values at baseline (42.3% infliximab vs 34.7% ustekinumab; aOR, 1.34; 95% CI, 0.79-2.28). Similar results were seen for all analyses performed within the propensity matched cohort.

Conclusions: Based on this post hoc analysis, infliximab and ustekinumab appear to have similar efficacy and speed of onset in patients with CD who are biologic-naïve.
