Uncertainty exists regarding safety and efficacy of dual biological therapy (DBT) in inflammatory bowel disease. We present four cases of DBT in Crohn's disease. Three patients had refractory disease non-responsive to biological monotherapy or combination therapy with immunomodulators. One patient had concomitant ankylosing spondylitis. DBT was implemented by combining vedolizumab with an anti tumour necrosis antibody or with ustekinumab. DBT was well-tolerated, though two patients did
