Abstract
Background
To present the real-world evidence on the safety and effectiveness of ustekinumab (UST) through 52-week treatment for Crohn's disease (CD) under an analysis of post-market surveillance data in Japan.
Methods
This prospective, post-marketing surveillance study was conducted in 341 patients from 91 medical facilities in Japan. Patients received UST 90 mg injected subcutaneously once every 12 weeks (or every 8 weeks if patients show weak effectiveness) after an induction dose given intravenously. Clinical response (100-point decrease in Crohn's Disease Activity Index [CDAI] score), clinical remission (CDAI score of <150), steroid-free clinical remission, C-reactive protein, endoscopy, physician global assessment, and adverse drug reactions (ADRs) were evaluated through 52 weeks.
Results
The overall rate of clinical remission was 49.2% at week 8 and 56.0% at week 52. The rate of clinical remission in biologic-naive patients was 75.9% and 66.7% at weeks 8 and 52, respectively, whereas the rate in biologic-experienced patients was 41.4% and 52.6% at weeks 8 and 52, respectively. For 52 weeks, the overall incidence of ADRs and serious adverse drug reactions (SADRs) was 11.7% and 6.7%, respectively. The most frequently reported SADRs was worsening of CD (1.8%). In multivariate analysis, ADRs incidence was significantly lower in patients with ileal involvement of CD (odds ratio = 0.25, 95% CI 0.07-0.85, P = .026), although disease location has no association with effectiveness of UST.
Conclusions
The present study identified no new safety concerns and effectiveness for CD in Japanese patients treated with UST.
