BACKGROUND: We compared real-world healthcare resource utilization (HRU), Crohn's disease (CD)-related complications, and time to systemic corticosteroid discontinuation between patients with CD treated with adalimumab versus vedolizumab as initial biologic.
METHODS: Biologic-naïve adults with CD and ≥2 claims between 05/20/2014 and 09/30/2019 for adalimumab or vedolizumab were identified in the IBM MarketScan research database. Patient characteristics were assessed during the 6-month baseline period before biologic initiation (index date). Adalimumab- and vedolizumab-treated patients were propensity score-matched 1:1 on demographics, disease characteristics, and comorbidities with ≥10% prevalence that differed significantly between groups. Categorical, continuous, and time-to-event outcomes between groups during the 12-month follow-up on/after index were compared with chi-square tests, Wilcoxon rank-sum tests, and Kaplan-Meier analyses, respectively.
RESULTS: Adalimumab- and vedolizumab-treated patients were matched (n = 461 per group) and baseline characteristics balanced. Significantly fewer adalimumab- versus vedolizumab-treated patients had a CD-related emergency room visit (12-month proportion: 14.5% vs 21.0%; log-rank P < 0.01) or inpatient admission (14.9% vs 20.2%; log-rank P < 0.05). Rates of CD-related surgeries were similar (9.3% vs 11.5%; log-rank P = 0.282). Among patients without internal/perianal abscess or fistula or intestinal stricture at baseline (N ADA = 360, N VDZ = 364), numerically but not significantly fewer adalimumab- versus vedolizumab-treated patients had CD-related complications at 12 months (18.3% vs 22.3%; P = 0.171). Among patients with corticosteroid use at index (N ADA = 143, N VDZ = 139), significantly more adalimumab- versus vedolizumab-treated patients discontinued corticosteroids (12-month proportion: 90.2% vs 76.3%; log-rank P < 0.001).
CONCLUSIONS: Patients with CD treated with adalimumab as their first biologic experienced significantly lower CD-related HRU and were more likely to discontinue corticosteroids compared to vedolizumab-treated patients.
