The Impact of Vedolizumab on COVID-19 Outcomes Among Adult IBD Patients in the SECURE-IBD Registry.

Abstract

BackgroundThe impact of immune-modifying therapies on outcomes of coronavirus disease 2019 [COVID-19] is variable. The purpose of this study was to determine the impact of vedolizumab [VDZ], a gut-selective anti-integrin, on COVID-19 outcomes in inflammatory bowel disease [IBD] patients.MethodsUsing data from the Surveillance of Coronavirus Under Research Exclusion for IBD [SECURE-IBD], an international registry of IBD patients with confirmed COVID-19, we studied the impact of VDZ on COVID-19 hospitalization and severe COVID-19 [intensive care unit stay, mechanical ventilation and/or death].ResultsOf 3647 adult patients on any IBD medication in the registry, 457 [12.5%] patients were on VDZ. On multivariable analyses using backward selection of covariates, VDZ use was not associated with hospitalization or severe COVID-19 when compared with patients on all other medications (adjusted odds ratio [aOR] 0.87; 95% confidence interval [CI] 0.71, 1.1 and aOR 0.95; 95% CI 0.53, 1.73, respectively). On comparing VDZ monotherapy to anti-tumour necrosis factor [anti-TNF] monotherapy, the odds for hospitalization, but not severe COVID-19, were higher [aOR CI 1.39; 95% CI 1.001, 1.90 and aOR 2.92; 95% CI 0.98, 8.71, respectively]. In an exploratory analysis, VDZ monotherapy, compared to anti-TNF monotherapy, was associated with new-onset gastrointestinal symptoms at the time of COVID-19, especially among patients whose IBD was in remission.ConclusionsCOVID-19 outcomes among IBD patients on VDZ are comparable to those on all other therapies. Hospitalization, but not severe COVID-19, is more likely with VDZ monotherapy than with anti-TNF monotherapy. Overall, VDZ appears to be safe in IBD patients with COVID-19.
