    Abstract:
    INTRODUCTION: Behçet's disease (BD) with intestinal, neurological (NBD), and vascular (VBD) manifestations often leads to poor outcomes. Infliximab is approved for the treatment of intestinal BD, NBD, and VBD in Japan; however, evidence regarding its safety and effectiveness in these patients is limited. We conducted a 2-year post-marketing surveillance to evaluate the safety and effectiveness of infliximab in patients with intestinal BD, NBD, and VBD in Japan. METHODS: This 2-year, multicenter, prospective, observational study included all patients with intestinal BD, NBD, or VBD, who had experienced an insufficient response to conventional therapies (e.g., glucocorticoids and immunosuppressants/immunomodulators), and initiated infliximab for the first time at participating medical institutions. The safety endpoints included adverse events and adverse drug reactions (ADRs), and the effectiveness endpoints included global improvement, and for patients with acute NBD, acute attacks. RESULTS: Between October 2015 and August 2018, 255 patients (171 intestinal BD, 49 NBD, and 51 VBD; including 16 with two disease types) were enrolled from 133 medical centers and treated with infliximab. Adverse events, ADRs, and serious ADRs occurred in 100 (39.2%), 72 (28.2%), and 38 (14.9%) patients, respectively; incidences were generally similar across intestinal BD, NBD, and VBD groups. No new safety concerns were identified. At the final evaluation, 68.8% of patients with intestinal BD showed improvement, most patients with chronic progressive NBD and VBD had not worsened (100% and 91.7%, respectively), and 93.3% of patients with acute NBD had no new acute attacks during the observation period. CONCLUSION: These results confirmed the safety and effectiveness of infliximab in clinical practice in 255 patients with intestinal BD, NBD, and VBD. There were no new safety concerns.
