Abstract
BACKGROUND: Our goal was to investigate the 3-year persistence rates with second-line vedolizumab and tumor necrosis factor-α (TNF-α) inhibitors (i.e., adalimumab, golimumab, infliximab) in patients with inflammatory bowel disease (IBD) who were followed in gastroenterology practices in Germany. METHODS: This study included patients aged ≥18 years who had received prescriptions for second-line biological drugs in Germany between 2014 and 2017 (n = 5,150) retrieved from the longitudinal prescription database. Vedolizumab users were matched to adalimumab, golimumab, and infliximab users based on age, sex, and index year. The primary outcome of the study was the rate of persistence with vedolizumab compared with the rate of persistence with adalimumab, golimumab, and infliximab within 3 years of second-line therapy initiation in IBD patients. Persistence was estimated as therapy time without discontinuation, with discontinuation being defined as at least 90 days without any prescription for the biological drug of interest. RESULTS: After matching patients who had received vedolizumab with those who had received adalimumab, the rate of persistence after 3 therapy years was 30.3% for vedolizumab and 27.9% for adalimumab (log-rank p = 0.005). The corresponding figures were 27.8 and 20.8% in the vedolizumab-golimumab matched-pair analysis (log-rank p < 0.001) and 29.5 and 25.2% in the vedolizumab-infliximab matched-pair analysis (log-rank p value = 0.008). Vedolizumab was associated with a significant 0.85-, 0.72-, and 0.86-fold decrease in the risk of discontinuation within 3 years of therapy initiation compared to adalimumab, golimumab, and infliximab, respectively. CONCLUSIONS: Treatment persistence was higher for vedolizumab than for TNF-α inhibitors up to 3 years after initiating second-line biological therapy.
