“…Almost half of patients with UC experience disease progression that necessitates the use of immunosuppressive therapies with steroids, thiopurines, and biologics (such as tumor necrosis factor inhibitors [TNFi], human interleukin-12/23 antagonist ustekinumab, or antiintegrin vedolizumab). [3,7] The effectiveness of biologics, predominantly anti-TNF agents, may wane over time as some patients may develop a neutralizing anti-drug antibody, necessitating an increase in dosage and/or frequency of administration, at the risk of more adverse events (AE).
