Abstract

BACKGROUND AND AIM: Re-induction with intravenous ustekinumab after secondary loss of response in Crohn's disease is a relatively new strategy to regain efficacy. This real-world cohort study aimed to evaluate its effectiveness and safety. METHODS: Crohn's disease patients with loss of response after initial response to ustekinumab and treated with a second intravenous dose of ustekinumab were included. Clinical, biochemical and endoscopic data were collected. Primary outcome was drug survival. Secondary effectiveness outcomes included clinical remission, primary nonresponse and adverse events. RESULTS: In total, 31 Crohn's disease patients were included after re-induction with intravenous ustekinumab. All patients had failed prior biologic therapy, that is 77% were exposed to two or more antitumor necrosis factor agents and 65% were exposed to vedolizumab prior to initiation of ustekinumab treatment. Median treatment duration between initial treatment and re-induction with intravenous ustekinumab was 11.1 months (interquartile range 6.9-19.5). Ustekinumab therapy after a second dose of intravenous ustekinumab was maintained in 74 and 71% of the patients at weeks 20 and 52. Clinical remission rates after re-induction at weeks 8, 20 and 52 were 37, 56 and 45%, respectively. Nonresponse occurred in 16% of the patients. Adverse events were reported in four patients. CONCLUSIONS: Re-induction with intravenous ustekinumab after secondary loss of response results in continuation of ustekinumab treatment for at least 1 year in almost three-quarters of patients and in clinical remission in half of patients after 1 year. Therefore, ustekinumab re-induction may be considered an important rescue treatment option in patients with refractory Crohn's disease.
