Vedolizumab use in patients with inflammatory bowel diseases undergoing surgery: clinical trials and post-marketing experience.
Ontology highlight
ABSTRACT: Background
Patients with inflammatory bowel diseases frequently require surgery, but immunotherapies used in disease management may increase the risk of post-operative complications. We investigated frequencies of post-operative complications in patients who received vedolizumab-a gut-selective antibody approved for the treatment of moderately to severely active ulcerative colitis and Crohn's disease-in clinical-trial and post-marketing settings.Methods
This post hoc analysis of safety data from GEMINI 1, GEMINI 2, and long-term safety studies included patients who had had colectomy or bowel surgery/resection. Data from the post-marketing Vedolizumab Global Safety Database were also analysed (data cutoff point: 19 May 2016). Adverse events relating to post-operative complications were identified using Medical Dictionary for Regulatory Activities preferred terms.Results
Of 58 total surgeries in patients included in GEMINI 1 and GEMINI 2, post-operative complications were reported for 3/51 vedolizumab-treated patients (5.9%) and 1/7 placebo-treated patients (14.3%). In the long-term safety study, 157/2,243 patients (7%) had colectomy or bowel surgery/resection; of these 157 patients who underwent surgery, 11 (7%) experienced a post-operative complication. Median time between last pre-operative vedolizumab dose and surgery was 23 days in GEMINI 1, 20 days in GEMINI 2, and 39‒40 days in the long-term safety study. In the post-marketing setting, based on data covering approximately 46,978 patient-years of vedolizumab exposure, post-operative complications were reported in 19 patients.Conclusions
In clinical trials, complications of colectomy and bowel surgery/resection appeared infrequent, with minimal difference between vedolizumab and placebo. The frequency of post-operative complications in the post-marketing setting appears low.
