Abstract
BACKGROUND AND AIM: Vedolizumab (VDZ) has been used in inflammatory bowel disease (IBD) patients who failed anti-tumor necrosis factor (TNF) therapy. This study was to examine long-term outcome of IBD patients switching to VDZ from anti-TNF agents for reasons other than failure of therapy.
METHODS: IBD patients at the University of Chicago IBD center who were in clinical remission with anti-TNF therapy and then electively changed to VDZ due to reasons other than loss of response were retrospectively analyzed. The primary outcome was the durability of clinical remission maintained by VDZ as assessed by Kaplan-Meier survival analysis. The proportion of patients in clinical and endoscopic remission at 6-12 months after switching to VDZ therapy was analyzed.
RESULTS: A total of 41 patients (36 with Crohn’s disease and 5 with ulcerative colitis) met the inclusion criteria and were in clinical remission at the time of switch. The majority of patients switched therapy due to adverse effects (56.1%) or infections (14.6%). During a median duration of 30 months (range 7-52) of VDZ therapy, 34 (82.9%) were in VDZ-maintained clinical remission. One (2.4%) and 4 (9.8%) patients discontinued VDZ due to flare and adverse effects, respectively. Endoscopic remission was present in 25 of 30 patients (83.3%) who had a follow-up colonoscopy.
CONCLUSIONS: VDZ was effective and safe in maintaining remission in IBD patients who switched from anti-TNF agents due to reasons other than failure of therapy. Our results suggest that switching anti-TNF remitters to VDZ treatment is a safe practice in specific patient populations.
